Happy Customers
Meg Welch
Great job of our new front door. They couldn’t have been more helpful and even fitted earlier than originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
Annette Clemons
Cannot recommend Britannia Windows enough! Joe & Keith, the installers were great – explained what was to be done, showed me everything I needed to know upon completion, very considerate & tidied up really nicely. Very friendly guys who are an asset to the team!!
I LOVE my new windows & door. Such an improvement.
Rachel Godfrey
We have been extremely pleased with Britannia’s service. From the initial quote through to installation they were great and really easy to communicate with. We had our conservatory roof replaced and they were by far the least pushy and most competitive in terms of pricing.
We can definitely recommend their services and will likely be returning again soon for a new front door!
Peter Burgess
Fantastic job from initial phone call through to final tidy-up.
Britannia provided great advice before purchasing my new windows and fitted them to a high standard being punctual and polite throughout.
No request was a problem and I will definitely be using them again and would recommend to friends and family.
Jerry G
Wow a fantastic job by both sales team and fitting team.
Sam provided excellent service and answered any questions that we had. Luke, Dave, Keith and Joe did a fab job at fitting the windows and doors. Never having had anything like this done before I was a little nervous but the guys were clean and tidy and the outcome is amazing.
Would highly recommend.
