How Much Is It to Replace Windows in the UK?

Rugby Editorial 26th Sep, 2023   0

With the energy prices jumping up and down, one thing keeps growing – summer temperatures. In fact, weather watchers predict that wetter winters and stuffy 40C summers will become our new reality.

The cold hard fact is that UK homes are not designed to withstand such heatwaves (pun intended). We’re finding ourselves in a situation where we need to prepare our dwellings to both warm us up and cool us down every now and then!

While opting for a fancy air-conditioner is what might first cross your mind, there’s another way to go. Have you thought about upgrading your windows?

This is a crucial aspect of home improvement, contributing to enhanced energy efficiency, aesthetics, and overall comfort.




For homeowners in the UK, replacing windows can provide numerous benefits, ranging from reduced energy bills to bearable summer temperatures.

However, before embarking on this venture, it’s essential to have a clear understanding of the average cost associated with such a project. In this article, we delve into the factors influencing the cost of new windows for UK homes.


Why Replace Windows In Your Flat?

This one question sets you on a life- and window-changing journey. If the windows at your property cause any of these issues, they need a replacement.

  • Drafts and Energy Efficiency: If you feel drafts of cold air near your windows, or if your heating or cooling bills have been consistently high, it could indicate that your windows are not providing adequate insulation.

    Windows with vinyl frames or argon gas-filled panes effectively reduce heat transfer through the glass, contributing to a cooler home during the summer.

  • Condensation: Excessive condensation between window panes can indicate seal failure, allowing moisture to penetrate the space between the glass. This can lead to reduced visibility and decreased energy efficiency.
  • Noise and Comfort: If you can hear outside noise even when your windows are closed, it suggests that your windows are not effectively soundproofing your home.
  • Fading or Damage to Interior: If you notice that your furniture, flooring, or interior decor is fading or showing signs of damage from UV rays, it could be an indication that your windows are not providing adequate UV protection.
  • High Maintenance Requirements: Wooden windows, in particular, require regular maintenance such as painting and sealing. If you find yourself spending a lot of time and effort on window upkeep, it might be worth considering low-maintenance options like uPVC or aluminium.
  • Increased Allergies or Dust: If you notice an increase in dust or allergies, it could be due to air leakage through your windows.

So whether it’s for aesthetics, health or energy-efficiency reason, new windows in any apartment lead to a more comfortable life.

Understanding The Variables

Several factors impact the average cost of new windows for a 3-bed house in the UK. These variables can include:

  • Window Material: The choice of window material significantly influences the cost. Common materials include uPVC, timber, aluminium, and composite.
  • Window Style: Different window styles, such as casement, sash, tilt-and-turn, and bay windows, come at varying costs. The complexity of design and features affects the overall price.
  • Glazing Options: Double glazing is the norm for energy efficiency, but advanced options like triple glazing or low-emissivity coatings can increase costs.

    For example, double glazing for a 3-bed house in the UK can cost between £4,000-£7,000 on average.

  • Window Size and Quantity: Larger windows or a higher number of windows will naturally lead to a higher cost due to the increased material and installation requirements.

    An average 3-bedroom semi-detached UK house has between 8 and 12 windows.

  • Installation Costs: The labour and installation charges, including the removal of old windows and the proper fitting of new ones, contribute to the overall expenditure.
  • Location: The cost of living and availability of local window suppliers and installers in your area can impact the overall price.
  • Additional Features: Extras like window accessories, hardware, security locks, and decorative elements can also add to the total cost.

Average Cost Estimates for a 3-Bed House

As of September 2021, the average cost of new windows for a 3-bed house in the UK can range between £3,500 to £8,000 or even more, depending on the factors mentioned above. To provide a better idea, let’s break down the costs:

  • uPVC Windows: On average, uPVC windows are often the most budget-friendly option, with prices typically ranging from £3,500 to £6,000 for a 3-bedroom house.
  • Timber Windows: Timber windows, known for their traditional charm and durability, can cost between £5,000 and £8,000.
  • Aluminum Windows: Sleek and modern aluminium windows generally fall in the price range of £4,000 to £7,000.

It’s important to note that these figures are approximate and can vary based on your specific requirements and location.

Investing in new windows for a 3-bedroom house in the UK is a valuable endeavour that enhances both the aesthetics and functionality of your home.

While the cost of the project may seem significant, the benefits of improved energy efficiency, increased property value, and enhanced living comfort make it a worthwhile expense.

Considering window replacement? Don’t do it all alone! It’s highly recommended to obtain multiple quotes from reputable suppliers and installers, allowing you to make an informed decision that aligns with your budget and preferences.
