How Much to Double Glaze a House in the UK in 2024?

A double-glazed window, also known as a double-paned window, has two panes of glass set into a frame. The two panes have an air pocket or intervening inert gases to help protect from glare and better insulate the house.

Every home is different with a unique style and more importantly the number of windows in different sizes.

Whatever the size of your house, there are often questions about the cost of double glazing a 2 bed house, cost of double glazing a 3 bed house, and cost of double glazing a 4 bed house UK.

Before we share some approximate costs, it is important to understand the factors that affect these costs. Let’s look at these factors and how they alter the costs:

Style of the Windows

The style of your windows is a major factor that impacts the average cost of double glazing 3 bed house UK. Different styles have different installation and manufacturing nuances, which influences the cost of double-glazing.

For instance, fixed windows that don’t open or casement windows, which open from a fixed single point are the easiest and least expensive to double-glaze.

Specialised windows such as bay windows, tilt and turn windows, and sash windows have more movable units and hence cost more to double glaze.

Size of the Windows

The larger the window size, the higher will be the cost of double glazing a 3 bed house UK. The size of the window is proportional to the amount of material and glass needed to upgrade it.

Installing bigger windows also takes more time. This leads to a higher cost of labour and hence more expensive to double-glaze.

Number of Windows

The number of windows in your house that you are planning to double-glaze has a direct impact on how much you will end up paying. Although it is assumed that the higher the number of windows, the more will be the cost of double-glazing them, it is not always so. The average cost for double glazing 3 bed semi UK will be higher than the cost of double-glazing windows in a 2 bed house.

If you are getting your windows double-glazed in bulk, the cost efficiencies increase and the manufacturer can often pass on some discounts to you. This usually means that the cost per window decreases with the increase in the total number of windows.

Windows Upstairs or Downstairs

The cost of double glazing a 3 bed terraced house or a 2 or 4 bedroom house is also impacted by which windows you are planning to upgrade.

Double-glazing windows on the ground floor is much easier. All the workers need to do is stand on the ground and work on the windows. When the windows are located on an upper floor, they would need to hire scaffoldings and other equipment. This can add to the total cost of double-glazing the windows.

Type of Glass

Another important consideration while budgeting the cost of double glazing a 2 bed house UK is the type of glass that you intend to use.

Window glasses come in every range depending on the degree of insulation, noise reduction, and better energy efficiency. They may differ in terms of:

The inert gas used
Upgraded solar protection
Aesthetics such as tinted, frosted, or patterned glass.
Special upgrades like the glass being self-cleaning.

What is the Cost of Resealing Double Glazed Windows
