The cost of double-glazing a 2-bed house in the UK can be influenced by various factors such as window frame materials, types of windows, and glass options and upgrades.

Understanding these factors will help you decide when investing in double glazing for your home.

Also, there is a range of payment methods for double-glazing a 2-bedroom house, including upfront payment and finance options, as well as government window grants in certain circumstances.

Window Frame Materials

The choice of window frame materials significantly influences the cost of double-glazing. Common materials include:

  • uPVC: the most cost-effective material, offering thermal efficiency, minimal maintenance, and a secure fit. It is available in various styles and finishes, catering to different tastes and preferences.
  • Aluminium is known for its strength and durability, but it can be more expensive than uPVC. It offers a sleek and modern look.
  • Timber: provides a traditional and natural aesthetic but requires more maintenance and can be more expensive than uPVC and aluminium.

For a 2-bed house, the approximate cost of double-glazing for uPVC casement windows ranges from £2,100 to £2,600, depending on the window size, glazing design, and the number of windows replaced.

On the other hand, timber frames and aluminium frames come with a higher price tag.

Wooden double-glazed windows cost 25% more than aluminium ones and 50% more than uPVC windows.

Strength, weather resistance, durability, and low maintenance requirements make aluminium windows popular.

Ultimately, the choice of frame material depends on your budget, preference, and the desired look for your home.

This pricing guide shows the average price you might be paying for your double-glazed window depending on its material:

 Material of Window  Average Cost of Window
 Aluminium  £950
 uPVC  £710
 Wood  £895


Types of Windows

The type of windows you choose will also impact the cost of double-glazing. Options include:

  • Casement windows: known for their robustness, safety, and energy efficiency
  • Sash windows: feature two sashes, with one stationary and the other movable, making them a popular choice for many homeowners
  • Bay windows: A bay window creates a beautiful focal point and provides panoramic views
  • Cottage windows: add charm and character to your home
  • Tilt & turn windows: offer versatility and ease of cleaning

For example, single-hung windows feature two sashes, one stationary and the other movable, making them a popular choice for many homeowners.

Casement windows are known for their robustness, safety, and energy efficiency. Sliding windows can be upgraded with energy-efficient glass and reinforced frames for increased durability and security.

Each window type comes with its unique set of features and benefits. Therefore, selecting windows that match your needs and preferences becomes a key consideration.

Remember that double-glazing costs will vary depending on the type and number of windows you opt for.

Below is a price chart that shows what new windows cost based on the style of a double-glazed window:

 Type of Window  uPVC Average Cost  Aluminium Average   Cost  Wood Average Cost
 Sash  £665  £700  £745
 Casement  £530  £645  £785
 Bay  £1,390  £1,615  £1,720

 Flush Casement  £540  £615  £675


Glass Options and Upgrades

The choice of glass options and upgrades also significantly affects the total cost of double-glazing.

Standard double-glazing consists of two glass panes with a gap between them filled with air or an inert gas such as argon for insulation.

Additional glass options include tinted glass, laminated glass, toughened glass, and acoustic double-glazing.

A Low-E coating can be applied to the glass to improve energy efficiency by reflecting heat back into the room, thus helping to reduce energy bills.

Choosing the right glass options for your double-glazing project will depend on your needs, such as security, noise reduction, and energy efficiency.

The cost of your double-glazing project may increase depending on the glass upgrades you choose.

Double-Glazing a 2-Bed House - Installation Process

If you are a homeowner interested in installing double-glazing in your house, you will want to know the process of it all and what happens.

Double-glazing a two-bedroom house involves several stages, from removing old windows and installing new double-glazed ones to making necessary adjustments.

Removal of Old Windows

Before installing your new double-glazed windows, the old windows must be removed. You may remove them to upgrade to double-glazing or have blown double-glazing in your windows.

Either way, this process typically involves:

  1. Removing any window stops or trim
  2. Unscrewing or prying off the interior wooden stops
  3. Extracting the lower and upper sashes
  4. Taking out the window frame from the opening
  5. Assisting in pulling the window out from the outside if necessary.

The cost of removing old windows will vary depending on their size and type and the complexity of the job. Generally, the cost can range from £50 to £200 per window.

Remember to factor these costs into your budget planning.

Fitting New Double-Glazed Windows in a 2-Bed House

Once the old windows have been removed, the new double-glazed windows can be installed. The window installation process involves the following:

  1. Measuring the window frame
  2. Cutting the plugs to size
  3. Inserting the plugs into the frame
  4. Securing the window frames
  5. Installing weatherstripping
  6. Caulking the edges

Professional installation is key to guaranteeing proper sealing and insulation.

The cost of double-glazing can increase if additional work or adjustments are required during the double-glazing installation process, which is why it’s important to choose experienced double-glazing installers.

Additional Work and Adjustments

In some cases, additional work and adjustments may be necessary to accommodate the new double-glazed window.

This could raise the total cost of double-glazing a 2-bed house in the UK in 2024. Necessary adjustments may include ensuring the window is properly aligned, sealed, and insulated.

Adjustments may also mean verifying that the window frames fit correctly, guaranteeing a proper seal, and ensuring sufficient insulation.

Potential additional costs should always be considered when planning your double-glazing budget.

Additional work will also be required for larger properties, which can increase the total cost of double-glazing the home.

The typical cost of double-glazing a 4-bed house will range from £6,300 to £9,700.

The amount changes depending on the size, style and material used for the double-glazed windows.

Double-Glazing a 2-Bed House Cost - Energy Efficiency

Double-glazing windows in a 2-bed house can improve energy efficiency through better insulation, noise reduction, and lower energy bills.

Here’s how these factors enhance the overall energy efficiency of your home:

Improved Insulation

Improved insulation is one of the main benefits of double-glazing. By incorporating two or more glass panes in a sealed unit, double-glazing provides better insulation than single-glazed windows.

This helps maintain a comfortable indoor temperature and reduces heat loss through windows, ultimately lowering energy costs.

The advantages of improved insulation include an all-around comfortable temperature, lower energy costs, and reduced sound levels inside the residence.

Noise Reduction

Noise reduction is another significant benefit of double-glazing. Double-glazing can significantly reduce sound levels by up to 35 decibels by having two glass panes with an air gap between them.

The greater the distance between the two panes of glass, the more effective the sound insulation. Here are some key points about noise reduction with double glazing:

  • Double glazing can reduce sound levels by up to 35 decibels.
  • The air gap between the two glass panes helps block out noise.
  • A 100-150mm gap between the panes provides optimal sound attenuation.

This feature helps create a quieter living environment, especially in areas with high noise pollution.

Lower Energy Bills

Improved insulation and reduced heat loss result in lower energy bills, making double-glazing a cost-effective investment. It is estimated that double-glazing can yield up to 20% savings on energy bills.

This is due to the increased insulation and decreased heat loss that double glazing provides, making it an ideal choice for homeowners looking to reduce their energy bills.


In conclusion, the cost of double-glazing a 2-bed house in the UK varies depending on factors such as property type, window frame materials, types of windows, and glass options and upgrades.

By understanding these factors and considering the potential energy efficiency benefits, you can make an informed decision when investing in double-glazing for your home.
