Customer Testimonials

January 2024

Conservatech have just built us a modern, insulated extension from the kitchen to the garden. From our first meeting with Allan to the last day I cannot fault this company. The whole team are polite, respectful, professional and a pleasure to have met them all. They all worked extremely hard and cleaned up every day before leaving. We would like to thank Allan, Eric, Jack, Keenan, Leon, Ayrron, Phil, Craig and Steve for everything they have done for us. We wish you all much deserved continued success. Ellie and Nev Hinchliffe

Conservatech replaced my 30 year old leaky conservatory with a very modern and insulated 'extension' which is open-plan from the house, including an orangery-style lantern roof light and triple bifold doors. From my first meeting with Allan to the final delivered product, everyone I worked with from Conservatech (Allan, Eric, Leon, Ayrron, Craig, Steve, Ellis, Jack, Phil and Charlie) were wonderful. Three of my neighbours commented on how polite they were. They worked hard, were professional, they cleaned the site every day, they didn't cut any corners, and they delivered an amazing product

One of the few exceptional companies we have dealt with over the years. Can highly recommend them for their professionalism, friendly approach and tidiness, especially as we have dogs. Just as important their after sales service was very good. Would have no hesitation in contacting Conserv-A-Tech to carry out additional work.

Brilliant Company! Worked to budget, finished within timeframe, helpful and supportive throughout. Highly recommend with no hesitation. From the very outset we felt reasurred with Conservatech. Eric drew up plans which he submitted successfully to Planning. He project managed everything, helping with ideas and advising options. We also opted to have the whole garden excavated and paved with new fencing which looks amazing! We cannot praise highly enough Eric's team who were friendly, reliable and trustworthy. Their high quality of work and attention to detail speaks for itself. V.Happy!

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.

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.

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.

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.

Customer in Hertfordshire

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.

Customer in Cambridgeshire

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.

Customer in Hertfordshire

he 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.

Customer in Central Bedfordshire

Excellent friendly service and excellent value for money compared to large National companies. Would certainly recommend them.

Customer in Hertfordshire

10 March 2021

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.

Customer in Luton

22 December 2020

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.

Customer in Cambridgeshire

9 December 2020

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. The fitters turned up when they were expected, were polite and tidy and worked to a high standard.

Customer in Hertfordshire

We can wholeheartedly recommend Conserv-a-tec. Workmen were friendly, accommodating and efficient. They left the work very cleanly. Once started everything was done on time when they said it would be. We are delighted with our new conservatory roof.

Customer in Hertfordshire

7 November 2020

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.

Customer in Bedford

25 June 2020

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.

Customer in Hertfordshire

Excellent work and organisation from start to finish. All trades, the designer, ground workers, bricklayer, fitters, plumber, electrician, Landscaper etc. were very professional, hard working, polite and courteous. Very pleased with the end result!

Customer in Greater London

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.

Customer in Hertfordshire

17 October 2019

Conserv-a-Tech staff were very professional throughout. The team was effecient, thorough, courteous and helpful and a pleasure to have at our home. We are delighted with the finish of the new roof.

Customer in Cambridgeshire

23 May 2019

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
