Despite a delay starting on site due to supply chain issues, the build progressed efficiently and has been completed to a high standard. Everyone involved was punctual, polite and tidy. There was good communication with the office throughout. I am really happy with my new conservatory and would definitely recommend Conservatech.

Contacted Conserv-a-tec to replace existing conservatory roof and join the conservatory to the house. Martin gave us a few ideas to play with and came up with a detailed drawing which we agreed best suited our needs. No pressure or false promises which made a refreshing change. All the tradesmen were polite, clean and tidy and very good at what they did. The final sign off and we are over the moon, has transformed a tired old cold conservatory into a room we cannot keep out of. Many thanks to the whole team.

Every single tradesman they sent was helpful, polite, worked efficiently and was more than happy to explain any part of the process. Our conservatory was dilapidated, so everything had to come down, leaving just a brick wall. The work began when they said it would and finished almost to the day they expected. Our biggest fear was at the beginning as we were doubtful about the number of reviews which appeared too good, but from the first visit it became obvious they weren't just salesmen. To say we are happy with their work is a massive understatement. The room has been transformed and we are grateful to all their workers for making the project such a success that we were sad to see them leave.

I cannot recommend this company highly enough - from the initial meeting we had such a good feeling about them, no pushy sales, just honest & knowledgeable and very competitively priced. The survey was really helpful and Eric came up with things I hadn't considered which I'm so grateful for now. They took away our old conservatory and it all happened so quickly, no waiting around for them to do other jobs. All the staff including all the tradesman are so polite, friendly and cleared up after each day, they were honestly a pleasure to have around and their attention to detail was second to none. Kim in the office is amazing too, so helpful, nothing is too much trouble. They have created the most beautiful space for us turning our old conservatory we rarely used into a modern extension we use every day! We could not be happier and I literally cannot say enough good things about this company. Nothing was too much trouble and they consulted us throughout. Don't look anywhere else you won't regret it.

The project was delayed by the Pandemic, but this was not an issue. The salesman was very efficient and produced excellent plans. The site visit was very good, everything was explained in detail including free removal of the old conservatory including carpet. The installers were great and clearly a good team. I would recommend Conserv-a tech if asked.

Outstanding company. Superb quality of workmanship. Attention to detail was second to none. The sales rep, surveyor, builders, installers, electrician, plasterer were all superb. The one area where they let themselves down was their communications, sometimes taking days to respond to emails and phone calls always going to voicemail. Apart from that, they were excellent. I would recommend them very highly and would most definitely use them again.

rude owner and had 3 roof glass panels implode over as many years. with kids in the house how risky is that. asked them to replace glass roof with a tiled roof so it's safer and he wants me to pay for this. nice attitude after spending £24000 on his conservatory products and can't use the conservatory as it's got glass all over the shattered panel which keeps dropping. 3 x this has happened, walk away

It is unfortunate that this customer has experienced some glass breakages initially after a year in June 2017, then again in September 2020 and again in July 2021 but on every occasion, we have responded and replaced the glass free of charge, and within a reasonable timescale corresponding with the customer at all times. The customer's request for an upgrade to a hybrid tiled roof was acknowledged and of course, this would not be done free of charge.....I am not rude, I merely advised that the tiled roof would be quoted if required. The title of his review is totally not a fair overview of Conserv-A-Tech!

We had our glass conservatory roof replaced with a livinroof which now means we can use the room all year round. The service was exceptional from quote to the finished installation. All workmen were polite and tidy using quality materials. The after service and communication has been very good and we would not hesitate to recommend this company.

An excellent job by Conservatech from the initial survey/quote to the finished result - it's like a whole new conservatory, and we're wondering why we put up with the old polycarb roof for so long! Great work by the fitters (Leon and Connor) - tidy, courteous, and hard-working in sometimes difficult weather. A couple of minor issues were sorted out quickly and efficiently by Eric and the team back at the office. We're absolutely delighted with the finished roof, and the 10-year guarantee that comes with it.

We chose this company as they were one of only a handful in our area who were able to fit the conservatory roof we wanted. In addition they replaced the windows. Aside from some delays in starting the work which we accepted were outside their control everything went very smoothly. The fitters turned up when they were expected, were polite and tidy and worked to a high standard. The one issue that arose was dealt with efficiently and without fuss.

New Ultraframe Conservatory Roof
Customer Service
Quality
Value
Our existing Ultraframe conservatory roof needed to be replaced. We did our research and chose Conserva-A-Tech over several other companies to do the work. That research paid off. Conserv-A-Tech stood out from most the other companies as a company that really knew about conservatories. Most of the other companies we contacted for quotations seemed to be in the conservatory business as a sideline to their core market of double glazed windows. With Conserv-A-Tech you got the impression that if something did go wrong they could fix it. Thankfully nothing did. Being a large roof to replace it was reassuring to have a professional conservatory company doing the work. The work they did was first class, from start to finish. We were very impressed with all aspects of the work, taking off and disposing of the old roof and installing the new one. We now have a brand new professionally designed Ultraframe roof to be proud of, all done to the agreed schedule and budget. Thank you Conserv-A-Tech.

Can't recommend this company enough. We were so fed up of our old leaky, too cold, too hot conservatory - it was a room I absolutely hated to be in. It is now my favourite room in the house. It's beautiful. Everyone we dealt with at the company so helpful and despite some issues with planning everyone so supportive and helpful at every stage, from planning, costs, build etc... Delighted with the outcome.

We were very happy and impressed with the work of the Conserv-a-tech. They replaced our conservatory roof that was leaking and also had a design problem. Eric redesigned the roof to make it technically much better and mor efficient. The whole team was extremely good, worked very well together and finished everything to our satisfaction.

Conservatech fitted a new glass roof on our conservatory to replace a failing polycarbonate roof. Working with them was a pleasure throughout. If you're in the market for a roof you'll likely be offered an Ultraframe roof- a good choice- by several companies so service is what divides them. Martin from sales was the most knowledgeable salesman we saw. Follow up was good, Eric who did detailed measurements was again informative and gave confidence in the company. The roof arrived early, another plus and the the fitting team were both charming and worked to a high standard. We've had a fair bit of work done on the house but this is probably the best all round service we've had. And they gave us the best price!

I would highly recommend Conserv-a-tech. From the initial quote through to the finished conservatory the process was smooth, professional and seemless. All the workmen were professional, tidy, polite and excellent at their jobs paying attention to detail. Any possible additional costs were communicated with us throughout so there were no nasty surprises. We love our new conservatory and have had lots of compliments on it. We would have no hesitation in using Conserv-a-tech again and recommending them to friends and family.

We had a replacement conservatory roof provided by Conserv-A-tech. We liked the company’s approach from the minute they arrived to quote for the job. Clear discussions and not hard sell. Once we placed the order we were kept informed on progress towards a fitting date. On the day the work started they protected the rest of the conservatory and kept the place tidy. The team was courteous and always on time. The workmanship is excellent and the new roof has transformed our conservatory. I would recommend this company to anyone looking to replace a conservatory roof.
