We now have a beautiful high-quality conservatory thanks to the huge amounts of skill and hard work provided by the outstanding team at Conserv-a-tech. From digging the foundations (lots of underground pipes to negotiate in our case) to final cleaning and finishing, we were so impressed. All of the installation team were a pleasure to deal with which is also a major bonus. A big thank you.

I chose Conserve-a-Tech due to the excellent reviews on the Which website. My conservatory roof had been leaking for some time, despite several visits by the original installers. I now have a wonderful new roof which looks fantastic. The service from every member of their staff I dealt with was excellent. The guys who did the job were amazing and not just the roof but the whole conservatory looks like new as they did such a wonderful job clearing up. I cannot praise them highly enough and wouldn’t hesitate to recommend them to anyone.

Fantastic conservatory

I now am the proud owner of a fantastic conservatory. Every single worker that came to put my conservatory up were polite and cleaned up after their works. They kept me updated as to who was coming next and what they would be doing. The works were tweaked because I had footing from my old conservatory which no one knew were there but Eric came out to check they would be suitable and that changed the works to be completed so it brought my works forward which pleased me as it meant the works were completed before I went on holiday. I had one sticky opener and they were out within a day just to adjust it which is not uncommon with new windows I know from experience.

Conserv-A-Tech stood out, as they were a local company. No high pressure sales from Martin Beech. Your money is registered with the Government Scheme, so both parties are protected. Eric Knappett, owner and Surveyor came and measured everything accurately, so that the order could be placed with Ultraframe. Kim in the office kept me updated. Phil, electrician made electrics safe. He found a few faults with my electrics and I had to contact my supplier to send an engineer to rectify. Leon and Ayyron, Installation Technicians were here for 3-days. Tidied as they went, so professional.

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.

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.
