Pros and cons

When shopping for windows for your home, you need to take time to consider different options and whether they are ideal for your home. To narrow down the alternatives, you can consider the benefits and downsides of installing the specific type of windows. Here are the pros and cons of Anglian double glazing windows.


  • Variety of styles and materials: You can choose between uPVC, natural wood or modern aluminium windows.

  • Security: Anglian double glazing windows are made from durable materials with tried and tested security features that are designed to withstand forced entry. 


  • Not the lowest finance rate: Although Anglian offers a 9.9% APR representative, it’s not as favourable compared to other brands like Britelite that have lower rates. 
  • There’s no fixed price: If you want to order Anglian double glazing windows, they don’t provide a fixed price. All the products are bespoke; therefore, you have to provide your specifications and requirements to get an accurate quote.

How do Anglian double glazing windows work?

Anglian double glazing windows use the latest technology to keep your house warm and safe. They consist of two panes of glass separated by a layer of trapped argon gas. This layer of argon gas has 67% of the thermal conductivity of normal air, meaning it’s a poor heat conductor. This keeps the warm air from escaping and trapped inside your home while stopping cold air from getting through to the inside pane of glass, improving the energy efficiency. The second pane of glass is important because it acts as a noise barrier. Apart from keeping your house warm, it blocks out noise and improves security.

How do Anglian double glazing windows compare with others?

Anglian double glazing windows have close competitors such as Britelite and Everest. Everest double glazing windows have an advantage over Anglian because they have a longer guarantee period. While Anglian offers 10 and 15 years, Everest has 10 or 20 years and lifetime guarantee options (for an extra cost).

Just like with Anglian, Everest windows have an A+ on uPVC casement windows and have an impressive list of accreditations, including FENSA, TrustMark, BFRC and BSI Kitemarks. Everest also offers the same range of materials as Anglian – uPVC, wood and aluminium. Everest also customises its prices depending on the customer’s needs.

Anglian double glazing windows also compete with Britelite. However, Britelite windows are only available in aluminium and uPVC. Additionally, they only have a 10-year guarantee compared to Anglian, which has a longer period for sealed units. While Britelite windows cost between £160 and £1,050, Anglian windows go up to £950. 

Both brands have an A+ rating on their double glazing windows. They are highly accredited and recognised for their high quality. Furthermore, they are made using glazing technology, making them energy efficient. They also keep your home quiet and safe.

How much do Anglian double glazing windows cost?

Anglian doesn’t provide a fixed cost for its double glazing windows because all products are made to measure. Once you get a quote from the Anglian website, the designers will arrange a home visit to take measurements and give you an exact quote. 

Since all the products are bespoke, your total cost will differ depending on the material, style, colour and any additional decorative features you will need. In addition, you need to factor in the installation costs. However, here is an estimate of how much you can expect to pay for the different types of windows:

Anglian double glazing windows are low-maintenance. You can clean them with water and soap regularly in case there’s a lot of dust. Avoid using harsh cleaning agents that could damage your windows. 

If you have uPVC windows, the frames and sills are pretty durable. These windows don’t decay like wood or aluminium. However, you need to regularly wipe them down because of dust build up. As long as you use non-abrasive materials, you don’t need a professional to help you with the maintenance.
