When you think of aluminium windows you often think of their slimline, contemporary aesthetics that are often seen in modern homes.   But what happens if you are have an older-style or listed building.  Can you still install aluminium windows into these types of properties?  The short answer is yes!

In many cases, aluminium windows will be your best option for listed buildings. However, unlike replacing windows in a standard, non-listed building, you will need to gain consent for the
replacement. Read on for more information about replacing windows in listed buildings – and why aluminium may be the right material for you.

The need to replace aluminium windows in listed buildings

Historic England, the public body that protects England’s historic environment, says that it is better to repair windows and doors on listed buildings rather than replace them.[1] However, sometimes it is necessary to replace windows in listed buildings. They might be beyond repair. They might need to be replaced to meet thermal efficiency requirements. They might have been replaced with historically inaccurate windows in the past and you are restoring them to their original heritage appearance.
Whatever the reason, when you do replace the windows, it is vitally important to use replacements that restore and enhance the beautiful heritage appearance.

Why aluminium windows are suitable for listed buildings

Aluminium windows have a wealth of benefits that mean they are ideal for use in listed buildings.
When you use aluminium windows, you gain modern-day thermal efficiency without compromising heritage aesthetics. This is because

aluminium windows are very strong. This means you can have double glazed windows with frames that are as slim as those on traditional, single glazed windows. This is useful if you are replacing original timber sliding sash windows. It is also useful for single glazed casement windows that need to be replaced too.
Many heritage buildings have iron or steel-framed windows. Aluminium windows are the logical material to use when replacing these because they closely reflect the aesthetics of the original material.
As well as their strength, aluminium windows are very versatile. They can be manufactured in virtually any shape, so they are suitable for most window apertures. Furthermore, they can also be coated in any colour that’s required, so they can replicate original paint finishes with no difficulty.

Gaining consent for replacing aluminium windows in listed buildings

If your house is listed, you should always seek advice before replacing windows because listed building consent may be required. The first step is to contact the planning department of your local authority. They will tell you what you need to do.
If your home is in a conservation area, restrictions may also apply. Again, speak to your local planning department before carrying out changes.
To be able to make a decision, your planning department is likely to need technical and visual information about the windows you would like to use. Your window installer will be invaluable here. You may find it useful to work with a supplier with experience of replacing windows in listed buildings. They will understand the requirements and be able to supply the relevant information.
