Cox Format Developments Limited

We used Cox Format for a rear extension and patio and are really happy with the outcome. Mark and the team were brilliant to work with, communication from start to end was great, and the build has been done to a very high standard. Would recommend.

We really enjoyed working with Mark and the building team at Cox format. Incredibly thorough, very responsive on phone/emails/whatsapp, pragmatic approach and helpful in guiding us through our decisions. They also had lots of great subcontractors to hand.

We used Cox to completely renovate our loft and some of the first floor. Our job was not at all straightforward as the old loft conversion had to be ripped out and effectively started again - but we were impressed with how quickly and professionally they completed the job, which finished on time. They are on site every morning by 730 and work solidly until 4. Communication was fantastic and we were particularly impressed with how they resolved inevitable issues that came up in the build. All their people are lovely, entirely trustworthy and very respectful - by the end of the build they felt like part of the family! Most importantly, we completely trusted them and would definitely use them again or recommend to others.

Really thorough preliminary discussions about the work required which was making improvements to a loft room i.e window seat,lighting,electrics,plastering and a new window.Started on time ,finished on time helpful through the whole process,checking with me that everything was satisfactory every day.Really clean and tidy ,I would absolutely recommend this company and have already done so.

We used Cox Format to extend and upgrade a 20 year old loft extension and also to remodel other areas including moving the kitchen into the middle of our mid terrace house. They were recommended by our architects and also by several neighbours which was a good start. After meeting Mark and Peter I was convinced that they were highly motivated to get the whole job complete in around 12 weeks which was important to us as we would be living in the property. I was extremely happy with the whole process and the end result. The Cox Site team expertly lead by James were all a pleasure to have in the house and made the whole job as stress free as possible. James does an incredible job of juggling shifting priorities, weather and people, very impressive. The subcontractors (Plumber, Electrician, Tiler, Plasterer) brought in were all equally likeable, honest and clearly part of an extended family of trades well used to working together. There were a couple of unexpected issues during the project (there always are some) and they were dealt with minimum fuss and cost. At all times I felt at ease and as a client and treated with empathy and respect. I wouldn't hesitate to work with them again in the future.

Having seen their mostly 5-star online reviews for loft builds, Cox Format were amongst the quotes solicited and were subsequently selected for what was a first major house project. The basic loft quotation was itemised professionally to an admirable level of detail, with optional additional works listed separately for any desired upgrades (e.g. Juliet balcony instead of standard dormer window). Work commenced per agreed date and proceeded quickly, with site attendance being daily (Mon-Fri) whatever the weather. Few builders would claim to deliver a quality loft build in just 6 weeks, but with Cox Format’s efficient and experienced project management team (thanks to Mark in the office and James onsite) this must be the norm as the 6-week completion was easily achieved. When issues arose, as they usually will, these were dealt with promptly. You’ll need to be proactive if wanting certain preferred finishes (e.g. valley tiles vs. more common zinc flashing for roof valleys) as most builders are creatures of habit and will go ahead with their standard practices if you don’t request otherwise. All in all, a potentially stressful experience went smoothly so am happy to recommend this company as, true to their word, they delivered the build “on budget, on time”.

I am delighted with the transformation of my home, which involved much more than a loft conversion, adding complexity to the project. Communication was excellent from the pre-contract stage to completion. I appreciate the time taken before building started, to work through the plans in detail (design as well as costs). The foreman and his team were friendly, reliable, hardworking and efficient, with the work completed on time. His communication with me, my neighbours and suppliers was always timely, relevant and helpful. I am very happy with the quality of work and would confidently entrust CFD to deliver other home improvements I am planning.

Cox Format built our single-storey ground floor extension, incorporating a new en suite and dining area and preparing the existing kitchen space for new units. As well as extensive construction, the works involved a new boiler and radiators, updating electrics and installing lantern skylights. In addition, they refurbished our upstairs bathroom, which involved re-routing drainage pipes and the digging of a new manhole. Their costing was fair for the quality of work provided and included the provision of drawings and the obtaining of planning permission. Where potential problems arose, they were proactive in recommending solutions and quick to reconsult both the architects and structural engineer to produce the desired result. Their workers were polite, punctual and skilled at their jobs, with a clear contact structure in place, involving a knowledgeable foreman and efficient, friendly project manager. I would highly recommend them.

As well as a loft conversion, Cox Format also remodelled the middle floor of our house. Communication from start to finish was excellent. James was fantastic managing the work and was always available and willing to offer time to talk through different aspects of the job. He has a great friendly and professional team who were ready to go at 0730 and worked through to 4pm. The work is of very high quality and it has transformed our house and the space we live in. Our home is our most valuable asset and we're pleased and grateful that we put our trust in Cox Format.

We are so pleased with our loft which the Cox team completed before Christmas. Overall the team were friendly and approachable, always happy to answer our questions etc. All the guys were great with our two young children and were always a pleasure to have on site - there was no bad behaviour or rudeness and they were so helpful when it came to moving furniture etc when the works were moving from room to room. Charlie and Luigi in particular were super helpful and Luigi's woodwork is excellent. We're really happy with it. We have also been super happy with the trades Cox put us in touch with: - Alan and his son did an excellent job on the tiling. - Del, the painter and decorator . But none of it would have been possible without James, the Project Manager/Foreman. We thought he was excellent and made the whole process run so smoothly. We know there were a few weeks when it was a crunch point on a few of his sites but he never made us feel rushed, always made time for us and was happy to help us understand more before we had to make any decisions. The client we met at Windsor Drive before we signed up for the works to be done gushed about him and now we can totally understand why. So professional and helpful and just generally a lovely bloke. The works were completed on time and in budget and no additional works (which we had asked for) were done without clearing costs with us first. Overall so glad we chose them. Everything worked out just how we wanted.

The whole process from start to finish was first class. Mark the project Manager was efficient and great to deal with. James the Forman was fantastic. He was very knowledgable, patient and really helped us make the right decisions. All the lads that worked on the job were highly skilled and very hard working. All in all we couldn’t be happier that we used Cox Format.

We wanted to say thank you so much for helping us renovate our house exactly the way we wanted. We have been very impressed with CFD, from our very first contact over a year ago all the way through to completion. During our initial meeting with Peter and Mark, we could see how professional, organised and honest they are, and this continued throughout our build project. Communication was clear and in writing, with no hidden costs or surprises. Any queries we had were always promptly dealt with. We had a loft conversion and extension done. All the work was done to the highest standard, and with incredible care, attention to detail and moreover respect for our home and family. They said our loft would be done in 6 weeks, and they were done bang on time. Our extension, 3 months - again right on the money. They turned up on time, every day come rain or shine and cleaned up after themselves at the end of the day. Not only did the builders do a sterling job, but so did all the subcontracted tradespeople. We have absolutely no hesitation in recommending Cox Format Developments for your building project: their slogan is they are “on budget, on time…every time” and for us they certainly lived up to that promise. Thanks to the whole team at Cox Format, what could have been a nightmare project has become our dream home. If you have a building project in mind and don’t know who to turn to, give Cox Format a call, you won’t regret it!

Thank you so much for doing such a fabulous job. It’s been a really busy few months work-wise for both me and Mas so having a team that has been totally on top of everything has been amazing. James has been totally on it from the start and Luigi and Charlie have been a pleasure to have round and really helpful. Thanks also for all your help.

We are very pleased with our decision to appoint Cox Format to undertake our kitchen extension. The whole team were a pleasure to work with – knowledgeable, helpful, extremely punctual and their work was all to a very high standard. We faced a few challenges along the way, notably having to dig the foundations down to 2.4m due to a neighbour’s tree, but the team were transparent and professional throughout the whole build. The finished result has transformed our home and we’d have absolutely no hesitation in using Cox Format for any future work we may undertake and would highly recommend them to anyone considering a building project on their home.

We approached Cox Format in October 21 for a quotation. The quotation was detailed and set everything out in a clear manner with respective coats. Right from the start they were professional, knowledgeable and showed great attention to detail. I formed this impression from day one and I was not disappointed. The work commenced in March 2022 and by the beginning of June 2022 we were done. The workmen were all highly skilled, craftsmen in their own right, professional and polite. They were; Luigi, Ash, Charlie and of course James the foreman. They always arrived every morning at 7:30am on the dot and worked throughout the day until 4pm. James who was absolutely great in coordinating all activities and informed us at every step of the way in terms of what was taking place on a daily bases. Mark, the project manager was a gem, he sorted out the work schedules and planned everything with James and Peter, the owner of the firm. We are really delighted with the finished result. The level of the finished work is the best that I have seen in a very long time and would highly recommend the firm for their work. If I need anything else I will be going to them first for advice. It was a real pleasure and not a chore to have this professional firm in my house for three months.

No hesitation in recommending Cox Format, incredible team of knowledgeable guys on site every day, working to our specific requirements at every stage of our loft conversion. We were impressed by their flexibility and responsiveness when we wanted to change a detail from our original plans, they adapted quickly, found a solution and made it happen. The team takes pride in their work, so we felt assured of a high quality finish. High quality work by a friendly, skilled team. We have already recommended them to friends and neighbours and would use them again if we did further building works. On budget and on time.

We decided to use Cox based on personal recommendation, and we are so pleased we did. Our plans weren't the most straightforward design but they were so willing to discuss options and any issues which has improved the final product. James and his team were a real pleasure to work with: always punctual and tidy with great communication throughout and the work was done to such a high standard. Despite the current supply difficulties we were always kept informed and nothing was held up significantly so the project was "on time" as per their company slogan! All their subcontractors were equally helpful and worked around the challenges that a 110-year-old house throws at you. We are so pleased with the result which has made a real difference not only to our house but the way we live in it. Thanks, James, Mark & Peter and all the team.

A very professional company, work completed on time, on a budget all done to a high standard. Highly recommended.

We cannot praise the team at Cox Format highly enough for their professionalism, efficiency and quality of work. Our loft conversion project was their first in 2020 after the national lockdown. We were naturally hesitant and we were working from home which was far from ideal with building works, yet the team ensured that we hardly knew they were there. They were so considerate of our work and our home. Every day they would brief us on the works taking place and every day they delivered. They were innovative, they were cooperative and they were so tidy. The day they broke through for the stairs we couldn't believe it hadn't always been that way - so mess free! Huge thanks to Mark, James and all the team for a hugely successful project. They finished on budget and on the exact date that they said they would complete. We would love to work with Cox Format again and we would have no hesitation in recommending them.

We used Cox Format to install a loft conversion. The whole team were extremley proffessional from start to finish. The work was carried out to an extremley high standard, the care and work ethic was outstanding, and the team were so tidy at the end of the day you would hardly know they had been there! The work was on budget and completed within 6 weeks. We are extremley pleased with the end result, which has improved our standard of living - highly recommend this builder!

Well, what can we say other than Cox Format delivered an exemplary loft extension during incredibly difficult times. The primary team, lead by James, had a work ethic we've never experienced from any other trade we've ever worked with. Come rain or shine, they were at our door at 7.30am waiting to start work. And, at the end of every day, they took the time and effort to ensure they left the house as tidy as it could possibly be. A huge thanks to James, Ash, Jack (and the rest of their team) for their enthusiasm and efforts to ensure we achieved the build we were trying to achieve. From a back office point of view, Mark (Project Manager) was always in contact ensuring we knew exactly what was going on. He was always on hand should we need anything. Did we have any minor issues? Yes, of course. What job wouldn't have any? But, were they sorted out? Absolutely. The Cox Format team take pride in owning any challenges and ensuring they are solved. Would we use Cox in the future? 100% yes. In fact, we've already contacted them to obtain a quote for our side extension! Finally, just to say a massive thank you to Cox for their work.

We had Cox Format complete our single storey rear extension. They took the project from start to end, using their in-house architect through to planning and the build. Our builders, Roy and Charlie were great. They worked incredibly well together and were quick, tidy and generally flawless in their craftsmanship. The brickwork was on point, with there not being a noticeable difference from the old build to the new. Mark was on hand to discuss any concerns, provide advice and dealt with the project throughout its entirety. We are very pleased with the finish. Thank you all at Cox Format.

Completed very professionally. Very happy with all the people involved and recomended. Finished on time and at the agreed budget. Thank you!

After several glowing recommendations from business acquaintances about work that Cox Format had undertaken for them, and finding I needed a new roof too, we booked a consultation with Peter Maton the CEO. Peter visited us with Mark Rossi who was to become our Project Manager. With both, their experience and professionalism was immediately evident and reassured us from the start. One of the things that really sets Cox Format apart is that they deal with the job from start to finish. They designed the loft along with all structural elements, and dealt with the council’s Planning and Building Control all the way through to sign-off. The other is that they have trained all their staff from an apprenticeship level and it really shows in comparison with other builders who tend to sub out a lot of work. We received a very professional quote along with information on how to notify our neighbours of Party Wall issues. Once we accepted the quote, Mark came back with James, who was our onsite Project Manager. James was exceptional – he really managed all on site elements of the job from start to finish. He kept the job on-track and to an incredibly high standard, even our neighbours couldn’t stop singing his praises. The advice, support and quality of the workmanship was superb. Cox Format had a slogan on their banner which went up on our scaffolding, “On budget, on time….every time.” They more than lived up to the promise and we wouldn’t hesitate to recommend them.

The job was to build an extension at the rear of the house for a wet room next to the small kitchen involving removal of an old toilet block which in turn would give further space to the kitchen. Plans and any queries were thoroughly talked through by the team with ourselves beforehand and throughout the job. Important to us. Payment was done as each stage of the job was completed and our satisfaction assured. The builder - professional - and crew were very hardworking, thoughtful, polite and tidied at the end if each day. The end result was a piece of craftsmanship - a creation of space one could not have imagined. We would recommend Cox for your building needs.

Well organised and good communication ensured a good job with minor issues promptly resolved. We are very pleased with the outcome and would recommend Cox Format to others.

We have had two lots of fairly minor repairs carried out by Cox Format, both were done very well by very pleasant workers - recommended.

We took our time to make a decision regarding building companies. With such a big project, we wanted to make sure we got it right. We could not be happier that we decided to go with Cox Format. The builders were all professional, courteous and respectful of ours and our neighbours' properties. They were always on time and tidied up at the end of every day. The foreman was clear in his communication and open to questions and concerns throughout the build. The project was completed on time, as projected, and we are beyond pleased with the quality of the work. No cutting corners, no "patch jobs"; they ensured that things were done right. Some companies may cost less, but you get what you pay for. I wouldn't hesitate to recommend Cox Format.

We had an L-shaped, double dormer, loft conversion on our Victorian terraced house. The work was completed on schedule in 6 weeks, despite bad weather, and was of an excellent standard. The whole team were professional and very easy to deal with. There was clear communication between all of the Cox format team, the project manager and ourselves, and queries and changes were dealt with in a timely manner. There was a clearly laid out payment plan with transparent costings. We would thoroughly recommend the company.

We recently completed an extension to the rear of our house. From the start of the design process through to the construction, Cox Format demonstrated professionalism, expertise and customer service with a clear passion for their business. It was clear from the start that their purpose was to ensure the clients expectations and satisfaction were met and put in the time and effort to ensure they met their goal. From start to finish the project went smoothly. We had regular meetings with the Project Manager to receive updates, review progress and discuss any changes. Any last minute changes were incorporated easily. The workforce turned up promptly every morning at 7AM and were respectful and trustworthy, and accomplished excellent work with paying attention to detail. Our home surroundings were protected to prevent any damage. We were impressed with the workmanship and speed with which the work progressed. The workplace was always left clean, tidy and safe at the end of the day. We've had an excellent experience with Cox Format and are very pleased with our finished product which was delivered on time and within budget. I would recommend Cox Format as our expectations were highly met and simply, quite stress free due to their organised and dedicated approach to their business.

We chose Cox Format to do our loft conversation because they're Which? Trusted Traders and we wanted a loft conversion done that required lowering some ceilings to make room. Cox's team were excellent at managing all aspects of the conversion, from completing the council paperwork, to providing detailed quotes and timelines. Mark, Project Manager, took into account all of our requirements and provided a lot of flexibility with additional tasks that we wanted done, such as custom spotlights and additional electrics. He also provided us with a timeline of work to help us manage expectation. A major plus was how quickly and professionally they built the loft, choosing additional manpower instead of sacrificing quality. We were able to see everything as it progressed, and the builders were happy to answer all of our questions. Everything was solidly built, finished, and plastered to a high degree. Both the builders and the subcontractors involved worked to a high standard while taking care of our house. Cox gave us an estimate of eight weeks to do the loft conversion. Eight weeks later the loft was complete and Cox Format delivered us the Final Certificate to show that it had passed all inspections. The build went smoothly, and we highly recommend them to anyone who wants a hassle-free loft extension.

Our project was to extend and completely remodel the back half of our terraced house. Cox format delivered the job to time and cost once our requested extras where factored in. They even managed to work around our daughters A Level revision timetable All work was professional and of high quality - we liked how tidy the work site was left each night Mark kept us informed throughout with regular updates and site meetings.

We engaged Cox Format to design and build our dormer loft conversion. They made well thought out plans with our input and took care of the planning permission and the subsequent appeal. They communicated the start date and from then on were at work solidly until they finished. Arriving everyday without fail at 0730 and getting straight to work. Starting at this time allowed us to discuss and take any decisions the team needed before leaving for work ourselves. The team were well presented, professional, polite and hard working, paid good attention to detail and always tidied up before leaving for the day. The back office staff produced a detailed quote and payment plan with an itemised list of any additional payments. I would absolutely recommend Cox Format for your loft conversion.

Cox Format have just finished an extension for us and it is excellent! When looking for a suitable builder we were seeking quality of workmanship, timeliness, cleanliness, friendliness and real value for money. Cox Format delivered all of these. They kept us well informed as the work progressed and listened when we sought any clarifications. They finished on time and to cost. We felt at ease throughout the whole build. All I can say is that I would recommend them without hesitation.

Good service and great quality of work carried out in a timely manner without cutting any corners. In the main they used there own directly employed workforce and kept a working project manager on site throughout. This was ideal as we had one point of contact and were able to build up the rapport and the trust which is essential when you have people at times working in your house unsupervised. Would definitely recommend Cox Format.

Cox Format has just completed our whole house refurbishment, including an attic conversion and a kitchen extension. They were professional, trustworthy and extremely easy to deal with throughout the project. Their project manager & foremen were excellent, and all queries and issues were dealt with promptly and effectively. Their original estimate time frame was about 4-5 months which we thought was very ambitious considering the size of our project, but they completed the whole project on time without any delays. Needless to say, the finished job was superb and we moved into our new house on time 2 weeks ago and are thrilled with all the work they have done! We can’t recommend Cox Format highly enough for their skill and professionalism.

The whole project ran like a military operation and if things fell behind due to unforeseen circumstances Cox Format caught up with things by sending in reinforcements. There were regular site visits by the Managers and constant feed back. We received helpful advice throughout. We were very pleased with the work which was finished to a high standard and on time and all of the workmen were very obliging.

Good quality work, pleasant and reliable people - recommended.

As we embarked upon our first renovation project we were excited though understandably a little apprehensive. Appointing Cox Format, we were rewarded with a definitive team lead by an efficient, highly skilled and organised foreman. Daily we were greeted with enthusiasm, reassurance and updates on each stage of the build. Astounded with the level of professionalism provided by the team, their understanding and respect gave us peace of mind and minimum disruption to our home. We couldn’t be more pleased with the completion of our loft conversion. The whole process was painless due to the competence of Cox Format. Grade A workmanship. With confidence and zero apprehension we look forward to Phase 2 of our home renovations and welcoming Cox Format back into our home. Mr & Mrs Te-Ng

This is the second time we've used Cox Format and we would definitely use them again. They are professional, polite and carried out the work within their estimated time frame and with a great finish. Thank you to the whole team. Mr and Mrs Destro

We used Cox Format for our house refurbishment and the external electrics and lighting for our garden. They had been highly recommended by several neighbours and did not disappoint. All their tradesmen were excellent, fully engaged, and reliable. Their electrician is I believe the best in the business. The few issues that appeared along the way were dealt with swiftly. They are an extremely pleasant company to deal with, and are unlike any other building firm we had come across. True professionals who really care! Peter runs a very tight ship and fully participated in the project and was on site on a very regular basis directing traffic. Mark was in charge of project management and ensured everything ran to plan with no downtime.

Using Which Trusted Traders website I chose 3 Companies to get quotes for this job. I chose Cox Format Developments Limited because they appeared competent & were able to do the complete package – design, building applications, complete build & certificates. Although a small job this was done very professionally. Once work began it continued every day until completion. It was done to a high standard & ALL the people who carried out the work were dependable, knew what they were doing and very pleasant. This was not the cheapest quote I got but you must remember your house is the biggest investment you have. So it was important to choose the correct people, you hear too many bad stories. Anyway the cost of the conversion increased the value of the house by more the cost of the build. The work was done on time and everyone at home was happy with the conversion. I would certainly recommend Cox Format for any building work. Chris 01/06/2017

We decided to appoint Cox Format for our loft conversion after considerable research, which included viewings of their work at other houses and a visit to their offices, which further instilled confidence. Their team are professional, reliable, courteous, and respectful of their customer's property and their wishes. Peter and Mark were continually visible, always addressed any slight issues we pointed out, and they ensured their contractors also worked to the same standards as their team. We have no hesitation in recommending them and their workmanship.

I had seen lots of development disaster stories on TV, hence i was slightly apprehensive when i decided to do a loft conversion. I obtained several quotes from builders but the minute i spoke with Cox format, i got the sense they were the sort of builders i had been looking for. They were thoroughly professional, specific, clear and transparent. Having viewed one of their recent projects, i proceeded with them for the build. My loft project started exactly on time, and each pre-defined stage proceeded with precision. Work was carried out on a daily basis (managed by James) and the major stages were completed ahead of schedule. Communication was superb, with almost daily updates on progress. Specifically, Mark had an unbelievably swift turnaround time when responding to my emails / texts / calls etc.. and this high standard was maintained from start to finish of the project duration...certainly exceeding my expectations. The quality of the work was excellent, and i have absolutely nothing to fault... which is really rare in my case. I would definitely use Cox format again and their number is already first on my list for any future development needs. I would recommended them in a heart beat.

I have had a loft conversion carried out recently by Cox Format ltd. Even though I had three additional quotes from other companies which were also competitive I eventually settled on Cox Format. I did this for several reasons. 1.They are an established company with a directly employed labour force. 2.The standard of their work is of the highest quality. 3.Their planning and co-ordination of material deliveries and different trades is first class. 4.They have excellent site supervision on the project from start to finish. 5.Any additional works outside the scope is clearly priced so there are no late surprises on budgets. 6.Perhaps and this is very rare despite promises they stick to their agreed programmes without comprising safety or quality. In conclusion they are a first class company who do exactly what they say and to programme.

We have now used Cox Format on 3 separate occasions over many years to carry out loft conversions and kitchen extension. They have consistently worked to a very high standard. In addition to great workmanship (with zero snagging / problems) they are timely, polite and courteous, and they respond to any queries / issues very promptly. Highly recommend.

The team were well organised and arrived on time every day. All trades were of very good standard and the finish to the build is excellent. Any small issues that we had were sorted out and the foreman was polite and made sure everything happened when it was supposed to. The job was completed on time and to a very high standard. I would recommend Cox Format.
