What sets Green Circle apart from other window manufacturer’s is not only their wonderful product and design but the fitting crew ; especially Steve, are first rate and nothing is overlooked or too much trouble – this has been the third company we have used and I would have no hesitation in utilising Green Circle again

I’m really pleased with the windows and doors. After having been initially surprised by the price of aluminium frames, I can honestly now say they’re worth every penny

The company make you feel a valued customer from start to finish of the process. The fitter has done a very good job at fitting the door for us and also advised us on aftercare maintenance. The doors are a fantastic addition to our renovated house, they are easy to operate and excellent value, as well as looking classy.
We’re absolutely delighted with our new doors – many thanks to the whole team for a job well done
Everything went smooth from start to finish, no problems.
Your wonderful windows will be the ‘Jewel in the Crown’ of our new extension, framing the waterside views
After 8 years of Green Circle Bi-fold usage…I thought I ought to maintain them a bit !!
I cleaned the grooves they run in, and sprayed silicon grease into the hinges, wheels and runners. There is no rust, no sign of wear, no loosening or wobble. They work as well as the day they were installed. Its a good product Kim. Thanks very much.
Interesting and reassuring to see the manufacturing process when we visited the first time
A first class company with an excellent product – designed and installed by a professional and friendly team. Please pass on our sincere thanks to all involved for making the whole experience such a pleasure
A Special Thank you for doing a Great Job, we truly appreciate your professionalism and attention to detail
Many thanks for a job well done, the finished project exceeded our expectations; we look forward to working with you in the near future on our ongoing project
Excellent customer service and a brilliant product. Expectations exceeded all round!
This is our second project with Green Circle. Once again the service has been absolutely first class from initial contact, through specification, ordering, delivery and after care. Green Circle is a truly professional company and an absolute pleasure to do business with. The product looks amazing in our house. We cannot recommend Green Circle highly enough. Many thanks to the whole team!
We would be delighted to recommend Green Circle as both their service & product was excellent
Everyone we dealt with was professional, courteous & knowledgeable. I would recommend Green Circle to anyone
Professional company with excellent fitters and a high quality product
We are so happy with our new Green Circle windows and patio doors. These were retro fitted recently to replace some UPVC units by another supplier, which were not that old but had caused us too many problems. Since getting these replaced by Green Circle windows and patio doors, we can really see and feel the quality. Condensation is no longer an issue, and they allow in much more light. They keep us warm and cosy. We would like to give Green Circle A++++++ for their service, the quality, look and smooth and easy operation of the patio doors and windows, for their excellent function and fit! We highly recommend you using this company.
Great product. Excellent service.
We are very happy with the whole process from the first contact to the final fix. Everyone has been very helpful and made us feel valued as customers on a personal level
Many thanks for a job well done. As you know we’re very exposed up here and I’m happy to report that after 2 winters our Bi-Folding doors are working perfectly and have stood up to the test of some very severe weather
Your communication was excellent throughout
Brilliant! The installation went really well and the installers cleaned up thoroughly – you’ve given the competition something to aspire to
A first rate installation throughout, from design, manufacture and install despite world wide problems with resin supply, I would not hesitate to use this company again for future projects !
Now the scaffolding has come down the windows have come into their own, the graphite frames are spectacular, ready contrasting against the stonework. It has been a pleasure working with the team at Green Circle, from the first initial visit to the last unit being fitted the help and advice has been priceless. Quality does come with a price, but it was worth every penny , a company is only as good as the staff that work there. 10/10 Green Circle. Thank you.
You were very helpful and patient with us, we appreciated your attention to detail, especially in the fitting stage. Very happy with the end product. Please pass on our thanks to the whole team
Good to work with the design team, and a very helpful site install manager
Many thanks for the installation yesterday, which was completed to a high standard. We would also like to compliment the installation team on their polite and obliging manner
We have another six windows and a door to order in the new-year and we will not consider any other supplier. I can recommend Green Circle without hesitation
Many thanks for our Sliding Doors – they look terrific and the guys who installed them worked very hard
Amazing service and everything completed on a very tight schedule – Thankyou for your help and efficiency completing the job well within time schedule !
