The Popular Choice
Casement windows are designed to minimise air leakage, which helps maintain a consistent indoor temperature all season. This feature is particularly beneficial in Fareham, where energy costs can be a concern for many homeowners, especially during the colder months. By reducing the need for artificial heating and cooling systems, these windows could lead to significant savings for your energy bills.
All our windows are supplied with double glazing as standard to further enhance their insulative properties. Our casement windows provide an additional layer of insulation, reducing heat loss and noise pollution, and resulting in a quieter, more comfortable living environment. For those who wish to further maximise their window’s performance, we offer the option of upgrading to triple glazing to provide an additional layer of protection to your home.
Designed For You
With their sleek design and ability to open outward, they provide beautifully unobstructed views and allow natural light to flood into your home. In Fareham, where picturesque views are abundant, our casement windows can significantly enhance the look of your property, adding a touch of elegance and modernity.
We understand that every home is unique, and windows are guaranteed to provide a perfect fit. Our vast range of customisation options allows residents to choose the size, colour, and finish that best complements their home. These windows not only enhance the aesthetic appeal but also ensure optimal performance and energy efficiency.

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.
