How much does it cost to install new windows?

When looking into what kind of window you want installed onto your property, the price of your installation will be dependent on the size and overall design of your windows.

This also includes how many windows you want to have installed.

A single window can cost as little as £200 to install, while 10 windows can easily cost around £2,000.

Again, this heavily varies on the type of window you have chosen. Some styles will cost as much as £500+ for installation, so it is best to know what kind of windows you want installed.

How does property size affect window costs?

As the size of the window can often dictate its price, it is natural to assume that the size of your property may also affect the overall cost of the installation.

Property Number of Windows Price
Flat 4 £2,100
House 8 £4,300
House 10 £5,400
House 15 £8,000

However, it isn’t so much the size of the property that affects the price of your windows, it is more to do with how many windows in it that you want to replace.

If you are planning on getting all of your windows replaced, having a larger the house typically insinuates that you have more windows to replace than a smaller property would.

If your house has around 8 windows needing to be replaced, this can cost you around £4,500, while a house with 10 windows would cost more at around £5,450.

Typically, every window that you want to replace will gradually increase the price of your installation because of the added work and materials.

How much does it cost to double glaze windows?

Getting double glazing is highly recommended. Not only does it provide stronger protection against the elements, but also provides far better levels of insulation. This helps you to bring down your heating bills, especially during the winter months.

Window Designs

Typically, a brand-new double-glazed window costs between £200 and £500 to have installed. However, if you want to keep your old window but still want to benefit from double glazing, there is also an option to have a sheet of secondary glazing fitted over your old window for around £100 to £200 per window. These window costs will either rise or decrease depending on the installer that you choose and where you are in the UK.

Double glazing vs Triple glazing

When looking into what kind of windows to get, you may have been recommended  both double glazing and triple glazing as ‘the best choice for your windows.’

But what exactly is the difference?

Double Glazing is made with two layers of glass, separated by a vacuum sealed chamber. This adds thickness to the glass and toughens it against excessive force, as well as creating a more thermally secure seal.

double glazed window costs

Triple Glazing has three layers of glass and two separate vacuum chambers. This claims to improve the security and the thermal insulation of the window.

The real difference, however, is in the pricing. While a double-glazed window typically costs around £350, a triple-glazed window will typically cost around £100 to £200 more.

Depending on where you live in the UK, double glazing should be sufficient enough.

How much do frame materials cost?

Another factor to take into account when considering the price of your double glazing window replacement is what materials the frame is being made out of.

There are three freely available materials offered by the vast majority of installation companies, each one with its own benefits, drawbacks and cost:

uPVC – the modern and most affordable and widely available material, it is the most popular and commonly used by homeowners throughout the country for their double-glazing solutions. A hardened resin made of unplasticised polyvinyl chloride, it is extremely durable and has a lifespan of up to 30 years. The cost of uPVC-framed double glazing windows typically start at around £250.

Wood / Timber – The traditional option, timber frames are often sought out for their ornate appearance. However, they can often be harder work to maintain than other frame materials, as they often need additional sanding, varnishing and repainting in order to keep their high-end appearance. Wooden window frames typically cost the same as uPVC to install, but do end up costing you more in terms of additional upkeep costs over the years.

Aluminium – Aluminium is becoming more and more popular as an option for double glazing windows and doors, often seen as the far more modern solution. Made of sustainable, natural materials, it is not as harmful to the environment as uPVC, and is also longer lasting. However, this does often mean that aluminium windows are a bit more expensive than uPVC.

Are wooden windows cheaper than uPVC?

While wooden and timber framed windows typically cost the same as uPVC windows in terms of installation, they can end up costing you more through their need for additional upkeep. Over the years wooden windows can suffer from natural wear-and-tear, meaning that to keep their appearance they need to occasional sanding, varnishing and repainting.

uPVC on the other hand is far more durable, lasting for 25-30 years before any signs of cracking or discolouring begin to show.

How much can double glazing save you?

The real perk to getting double glazing installed onto your property is that with the added thermal insulation that these new windows give you, you can save a lot of money on your energy bills.

The extra thickness of the double glazing in your new windows provides a barrier to prevent the warm air inside your house from escaping outside, as well as blocking any cold air from coming in from the outside. This is especially beneficial in winter, as your home will remain warmer for longer and means that you will not be as reliant on your central heating.

Overtime, the amount of money that you can save on your heating means that often the windows will end up paying for themselves. While the amount of money saved often relies on the energy rating of the windows themselves, you can easily save up to £120 a year in heating bills.
