y 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.

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.

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

5 October 2021

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

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

Customer in Essex

Repeat Customer in Hitchin

Conserv-a-Tech offered us a very professional and friendly approach right from our initial enquiry, providing us with some new ideas for our refurbishment plans to update our very dated conservatory. The whole team were all very polite and worked with confidence throughout the whole project. Keeping the work area tidy and they also cleared up at the end of each days work. Our refurbishment also included the need for an electrician and a plasterer who both provided a high class installations and finish. I would highly recommend this company to anyone

Customer in Knebworth

24 August 2017

Great team to work with - from design to installation everyone was really friendly and courteous. Good workmanship, hard working, patient, reliable and attentive, taking any issues of mine on board as we went through project. I've had loads of work done on the house over the last ten years and this was by far the best team I have dealt with. Very reliable. How often can you say that? Obviously for a project of this size there were some issues as we went along but they were all dealt with without any significant hassle or inconvenience. Delighted with finished product. Thoroughly recommended.

Customer in Stevenage

4 June 2017

After using Conservatech for our new windows and doors last year and being so impressed with them there was only one company we wanted to use for our garage conversion. Eric the owner had some excellent ideas on how we could convert the garage into two rooms and knock through into our living room. Again the quality of workmanship was excellent and the finished project looks amazing. Eric handled all building regulations and we had certification provided within a couple of weeks of the project finishing.
