About

Cox Format Developments Limited is a professional building company. The majority of our work is through personal recommendations. We are always happy to show previous work and our customers are happy to let you look! We pride ourselves on quoting a good price and sticking to it. Unless you instruct us to, we never add on "extras" as some less reputable builders do as their standard practice.

Because we are professionals, we can see what work is necessary to achieve your objectives, and we price accordingly. Others may quote cheaper initially, then add on what they see as "unforeseen extras". We believe our work is cheaper for the client in the long run.

On Budget... On Time... Everytime.

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.

Rear Extension

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.

Design and Build Loft Conversion

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.

Loft Conversion. A Great Job in a Timely Manner

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.

Whole House Refurbishment

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.
