How do Britannia double glazing windows work?
Britannia’s double glazing windows are made with two glass panes of a U-value of around 1.2, which is quite effective in providing insulation, as the lower the U-value, the better the insulation.
The two layered glass panes create a gap that is filled with argon – a dense gas with thermal conductivity that is 67% of that of normal air, making it a poor conductor of heat. The argon gas insulates cold air from travelling between the glass planes. It also insulates against warm air inside your home from escaping, thus keeping the inside of the house warm.
The panes also make noise a barrier, keeping your home quiet.
How do Britannia double glazing windows compare to others?
Britannia double glazing windows offer all the essential features that a double-glazed window should provide at a competitive price. However, with the company’s limited service area, consumers living outside of these areas will have to look elsewhere.
Safestyle is a good alternative, serving England and Wales. The company offers competitive pricing, but it only offers uPVC windows, unlike Britannia which also produces aluminium windows. However, Safestyle advertises itself as an eco-friendly window installer and recycles material from old windows where possible, even offering a buy-back scheme to help customers save money on window replacements.
Anglian also covers much of the UK and its prices are on par with Britannia for the most part, but it offers a wider selection of materials, including uPVC, timber and aluminium. However, one downside of Anglian is its limited finance options compared to Britannia, which has multiple schemes for customers to choose from.

They also have low-cost finance options. Through these options, you can either buy through low monthly instalments, interest-free credit or buy now, pay later.
If you decide to go with interest-free credit, you’ll have to deposit 25% of the total cost and spread the rest over 10 months at 0% APR.
If you choose to buy now and pay later, you’ll deposit 25% of the total cost and repay the rest within nine months at a 0% interest rate (£29 exit fee applies) or after nine months, pay the remaining amount within 12 months at 11.9% APR.
In the low monthly repayment, you’ll have to deposit 25% of the total cost and spread the remaining cost over five or 10 years at 8.9% APR. The best part about this option is that you can make additional repayments at any time, which can help reduce the loan term and total interest payable.
Installing and maintaining Britannia double glazing windows
When you contact Britannia for a quote, they will arrange an appointment with a sales representative to go over all the options available, including styles, colours, materials and window furniture. They will also take rough measurements of your windows to set up an estimate of the cost. If you decide to go ahead, a surveyor will then come to your home to take more accurate measurements, which will be sent to the factory to make your windows. When they’re ready, the team will arrange a time that’s suitable for you to install your windows. A technician will do a quality check on the work and then demonstrate how to use your new windows. The company also offers an aftercare service should anything go wrong after your installation.
It’s advisable to do routine maintenance to the windows on your own twice a year to help them last as long as possible. That includes washing all exposed areas with warm soapy water using a soft cloth and then drying thoroughly. Wipe clean any area exposed when the window is open to remove grime, dirt, dead insects, or old lubricant. After cleaning, apply a light layer of petroleum jelly to keep the locking system in working order.
If you live near a salty environment like the coast or near construction sites with more dust and dirt in the air, you may need to schedule more than two annual cleans.

“We have had our front door replaced with a composite door and frame from Britannia Windows in Clevedon. We were so pleased with the quality and price we later purchased two new windows and a large four-panel patio door. The quality of the all the very good. All windows and doors work very effectively, the fitter was efficient and spotted a small scratch on one of the glass panes, which I had not seen, and even when pointed out to me, I was struggling to see. This page was replaced within a few weeks or so with no hassle. The salesperson, surveyor and fitters were all very good at their jobs. I will have no hesitation in using or recommending Britannia in the future.”
- MR Micheal Wood, AllChecked
“Excellent service and competitive price, and I would have no hesitation using Britannia Windows again. Very good engagement initially at the Brislington showroom, where our queries were all answered. Surveyor identified some changes which were carried through to manufacture and installation. Problems on site that demanded a non-standard fix were dealt with very effectively by the installation team. Finally, the door magnet and plastic finishing pieces (extras) were delivered to the door by Brittania. All are very satisfactory, and I am very happy to give a 5* rating.”
