Frequently Asked Questions
Take a look at some of the questions previous customers have asked regarding our windows. If there’s something we haven’t covered, contact us online or over the phone to talk to our expert team today.
Can I expect energy savings with my new windows?
This depends on the windows you had before, but in most cases, yes! If you are upgrading from single to double glazing, or double to triple glazing, then you will definitely notice a difference between the amount you spend on heating over the winter. If the windows you are replacing are fairly old, it is likely that the seal in their frames isn’t as efficient, so draughts might be slipping through and further reducing the efficiency of your windows.
Installing brand new, expertly installed double or triple glazing windows is likely to result in energy savings, but you’ll notice the difference most acutely if you are upgrading from single glazing.
What type of glazing should I get?
The standard glazing offered by most window companies is double glazing, although not all double glazing is created equal. We’ve found a 28mm unit with a 20mm gap between the panes to be the most energy efficient and noise reducing, so we offer this in all our double glazed windows. Single glazing is very inefficient and causes condensation, and is rarely installed in new properties.
If you live in a very cold area and want the best thermal efficiency on the market, then contact us to talk about triple glazing; with three panes of glass and two gaps, it is ideal for exposed rural properties.
Is there a warranty?
Our products carry a written guarantee of up to 10 years. This means that we are as invested as you are in giving you the best quality products, installed to the highest standard. The guarantee may be for 10 years, but the majority will last much longer than this provided that they are cared for properly. When we install, we’ll explain the best way to maintain them.

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.
