I have used Zen twice for double glazing. The new windows make a big difference to keeping heat in and noise out. Both times, Zen have been helpful, clear about what will happen & when, have kept their promises and treated my home with respect.

So pleased we picked Zen for our window installation. Right from the start they understood what we were looking to achieve and made our bespoke requests a reality. Nothing was too much trouble and we never felt pressured, even when we experienced delays to the start date due to separate building works. The fitters were excellent; really skilled at what they do with excellent attention to detail and good communication. The house feels warmer, is noticeably quieter and more ventilated, and it looks stunning too! I wouldn’t hesitate to recommend Zen to anyone looking for new windows and doors.

Zen sorted two windows for us and were fantastic from quote to installation… No pushy sales people, competitive quote, clear schedule and payment terms and fab installers who came on time and left the place spotless! The new windows have made a massive difference to how warm the rooms are and I have every confidence if we ever get any issues that Zen will be swift to resolve them. If we knew it was this easy we would have sorted the windows ages ago!

Tom, Bristol

Zen have been fantastic to work with from start to finish and I cannot recommend them highly enough! Ben provided our quote and advice on what options we could consider. He was polite and clear and a pleasure to talk to. Stacey arranged our installation and has been a great communicator throughout. James and Kieran completed the fitting. They were so tidy! They worked really quickly and left us with an amazing set of new windows. We’re warmer, it’s quieter and we’re delighted!

Katie, Bristol

Excellent service from this company. They installed a new sliding door and kitchen window for us, the price was good and the result top quality. The fitters were polite and very hard working. A great company.

Helen, Bristol

Excellent service from start to finish, from every member of the team. Great communication throughout, with swift responses to any queries or concerns. The workmanship is of high quality, and the workmen tidy, friendly and respectful. Highly recommended.

Naomi, Bristol

Very happy with my new windows installed by ZEN. The whole process went smoothly, from the initial no pressure visit and quote from Ben, to the fitters themselves who did a great job and were punctual, tidy and pleasant to have around. Would have no hesitation in recommending ZEN windows.

Sue, Bristol

Our front door was fitted with no fuss and earlier than expected. Our old door had large gaping holes around the sides and wasn't secure. The new door was expertly fitted by Zen, solutions were found to make sure we get the best insulation. It looks beautiful. The installer was very considerate and addressed all of our concerns.

Aisle, Bristol

All went very smoothly. Staff kept to appointments and the work was completed on time and to a good standard. Everyone was helpful and polite. I am very pleased with my new door and windows and would highly recommend this company.

Jane, Bristol

Fantastic service from start to finish. Had previous work done by this company so didn't hesitate to see them first this time round. Good time keeping, accommodated my needs very well. Workmanship is very good. Overall service I'm very happy with.

Rachael, Bristol

Matt made the whole process from the initial contact to completing the job easy. Being a landlord living abroad made it more difficult to find someone I could trust to do the work whilst I am not there. Communication with myself and the tenant was efficient, photos of the completed job were sent and my tenant was very happy with the way the work was carried out. Windows and patio door look great. I would definitely recommend ZEN!

Jane K, Bristol

Glad I choose Zen Windows to replace our old single glazed bay windows with new units and glazing. Matt came round and was very helpful in getting us a quote with no pressure whatsoever. They were well priced, easy to communicate with and then Andy and Archie did a great job - courteous, helpful and hardworking.

Tim, Bristol

We were very impressed with Zen Windows throughout the whole process. From the initial salesman to the quotation, fitting and finally invoicing was completed with the utmost professionalism. The job was finished on time and to the highest standards. I could not fault Andy and Archie on how they conducted themselves and their workmanship, going above and beyond what was expected. A great job all round and we couldn't be happier.

Philip, Bristol

Excellent service and a super professional installation team.

Raphael, Bristol

Met with 2 guys to discuss the works required - very friendly, kept everything simple and no pushy sales tactics. Once agreed to go ahead with the works, their office rang me up to arrange a suitable date to have the works completed.

The guys who completed the work were very courteous (Partner was working from home at the time) and did an amazing job from start to finish! The quality of their work was great and would 100% use ZEN again for any future works. 

Ryan, Bristol

Amazing. The service we have had from start to finish has been amazing, the whole team are lovely, communicative, respectful and friendly

Emily & Ant, Bristol

Everything was well organised from the first contacts, measuring, day of fitting to the final finishing up.

P. Whiffen, Bristol

From start to finish the communication was clear and helpful. This is not the first time I have used ZEN. The Fitters are efficient and prepare everything before they start covering the carpet and even though you know with ZEN it will be spot on they check again before they take the old windows out, which is in my view good practice. 

Thanks for another great job, no hesitation in recommending ZEN as a supplier and I will be back again to use their service, thanks guys and Stacey again!

Jackie R, Bristol

All excellent. Highly recommend this company. AlI went weII from start to finish.

H.R, Bristol

Windows were fitted late 2023 and the weather was awful. Andy and Archie worked inside and out and must have been soaked by the end of the first day. They were always cheerful and courteous and it was a pleasure to have them in the house. They cleaned as they went along and took all the rubbish away with them. 

The front door was fitted a few weeks later as there was a delay on the glass panels. I can highly recommend ZEN Windows and thank Andy and Archie for their hard work.

Wendy T, Bristol

We found the complete service from initial enquiry and quotation through to fitting and billing to be efficient and thorough The fitters themselves were very pleasant, tidy and a pleasure to have in our home. Would thoroughly recommend Zen Windows

Sally Eccles

We were very impressed with Zen Windows throughout the process. We approached them to come and quote for us after reading the many positive reviews online. The initial salesman was very good. He built a rapport and listened to what we wanted. He made some good suggestions as to what we did for some of our windows. At no point was there any pressure to buy. The team of installers were great and did an excellent job of clearing up after themselves every day. We are really pleased with the result and highly recommend Zen Windows.

Sarah Bird

The whole experience with Zen windows has been fantastic start to finish. All my questions before the job were answered quickly and comprehensively, the fitters were friendly, tidy and did a wonderful job. I wouldn't hesitate to recommend them to anyone!!

Sam Ferrins

Made the whole process so easy and straightforward, thank you for your help. I would certainly use again and will recommend to others!
