Having wanted to have an extension on our house we consulted the team at Conserv-a-tech. Eric had come up with a bespoke plan that had ticked all the boxes of what we required. Jack, Leon, Ayron and the rest of the build team were simply outstanding. Every evening all tools were cleared up, all working areas were cleared and their pace of work was insane. The standards of the work completed beat our expectations. Eric had gone above and beyond in terms of helping us out and I would definitely recommend Conserv-a-tech for anyone wanting to improve their living space.

Conserv-a-tech are an extremely professional company. There was excellent communication and calls were always returned. The work was carried out with the minimum of disruption and the team were great. We did have a hitch on completion but it was fully recognised and Conser-a-tech acknowledged and dealt with it in a very professional way. The issue was completely resolved and we couldn’t be happier with the finished job which has exceeded our expectations. We would recommend this company to anyone.

We had our leaking, old conservatory roof replaced with a tiled roof and also had new windows and doors replaced. After meeting Alan and Eric everything was done on time and very professionally. They both suggested ideas for our conservatory which we're very welcome. The drawings of the design were very clear and we were kept up to speed regularly via e-mail and phone calls while the the roof etc were being made. We were given plenty of notice as to the start date. The fitters were excellent, with minimum disruption and had to work in challenging weather conditions. Everything was left secure, clean and tidy after each day. Kim, the secretary / admin assistant always informed us promptly when the company had received our staggered payments. We are really enjoying our new conservatory, it looks amazing, warmer and we spend alot of time in it already relaxing. We would thoroughly recommend the company and thank you Eric and Alan for your wonderful team, who are a credit to you.

I had a considerable amount of work carried out on my house by this super company. A 'warm roof' brick built extension on my kitchen, An amazing orrangery to replace the original, rather tired conservatory. All the windows replaced with flush casement windows (Iove them) and all external doors replaced. Extensive work carried out externally... existing patio lifted and relaid, new paving slabs laid around the garage and extension, and new fences and gates. I could go on..!! I just want to say thank you Eric. You have a fabulous, hard working and conscientious team who worked in some awful weather conditions who on a lighter note managed to go through a mountain of sugar and teabags and a leaning tower of Piza stack of coffee pods and biscuits! All work is guaranteed and I do feel confident that if any issues/problems were to arise in the future they would be dealt with accordingly.

I contacted Conservatech to fit me a new garage back door as I was very impressed with the work they did when they replaced my old conservatory a few years ago. A Very friendly and a high standard of work from all who were involved in the job. Thank you.

Conserv-A-Tech is a standout company. From start to finish, they have been exceptional: from Allan's advice on beautiful thirties-style windows and Eric's thorough structural checks for the bay window replacement to the quality installation by Craig, Steve, and Ellis. Kim, who was in the office, also kept me updated. I discovered that the old aluminium frame windows I'd lived with for 23 years had not been installed correctly, and the bay roof void needed to be insulated. I had been living in a wind tunnel—but no longer. The new windows have transformed my property. They are stunning - and I look forward to the energy savings they will bring this winter. The work was carried out as scheduled, and the team happily answered all my questions. They are true professionals who take pride in what they do. I have asked Conserv-A-Tech back to undertake more work at my home.

After a few years putting off the rebuild of our old, wooden conservatory we are delighted with the finished result. We wanted something that would not look out of place with our character property and garden and this blends in really well. it also has all the positives of a modern extension. From the beginning with Allan talking us through the plans, colours etc to Eric and his team, especially Leon and Arryon, with the actual construction, they were all very professional, polite, clean and tidy. Would 100% recommend
