How to Budget for Double Glazing in Your Terraced House: A Cost Breakdown

In the United Kingdom, double glazing is no longer a luxury but a necessity, especially given the stringent building regulations that have standardised this feature since April 2022. The benefits of double-glazed windows—ranging from significant reductions in carbon emissions to enhanced comfort and energy efficiency—are well-documented. However, the cost of double-glazing a 3 bed terraced house and, indeed, any home can vary widely. This guide aims to demystify these costs, helping homeowners make informed decisions when considering this crucial upgrade.

Understanding Double Glazing

Double glazing is a window technology where two panes of glass are placed in a frame with a gap between them, which can be filled with air or inert gases like argon or krypton. This gap acts as an insulating barrier that reduces heat transfer, improves energy efficiency, and enhances the acoustic properties of the window, making it an effective solution for both thermal insulation and noise reduction.

The cost of double glazed windows is influenced by various factors, making it difficult to provide a one-size-fits-all answer. The price is dependent on the dimensions and style of the windows—ranging from standard casement windows to more elaborate designs like bay or tilt-and-turn windows. The number of windows needed, their installation location (with accessibility and local labour rates playing a role), the chosen glass type, whether standard, toughened, or with special coatings for additional benefits like UV protection, also significantly affect the overall cost.

Furthermore, opting for frames made from uPVC, aluminium, or wood can impact the price due to the differing materials’ cost and durability. High-quality double glazing not only offers immediate benefits in terms of comfort and reduced energy bills but also adds to the property’s value, making it a worthwhile investment despite the initial outlay. Thus, while the cost can vary widely, the long-term savings and advantages often justify the expense.

Factors Influencing Double Glazing Costs

The cost of double glazing is influenced by several key factors, each playing a crucial role in determining the final price. Understanding these can help homeowners make informed decisions about their investment in energy-efficient windows.

1. Style of the Windows: The design and operational complexity of the windows significantly affect the cost. Basic, fixed windows are typically the most economical option due to their simplicity. In contrast, more intricate designs like bay windows, which extend outward from the wall creating additional space and light, tilt and turn windows, offering versatility in opening, and traditional sash windows, which slide vertically, are more costly. These styles involve more complex mechanisms and require more materials and labour to manufacture and install.

2. Size of the Windows: Larger windows necessitate more glass and framing material, leading to higher costs. The size not only impacts the amount of materials used but also the labour involved in handling and installing these larger units. As window size increases, so does the price, reflecting the additional resources and effort required.

3. Number of Windows: The total number of windows being installed or replaced also plays a significant role in the cost calculation. Installing multiple windows at once can lead to higher overall costs; however, bulk orders often qualify for discounts. These discounts can lower the average cost per window, offering savings that wouldn’t be available when ordering windows individually.

4. Location of Windows: The installation location affects the cost due to accessibility challenges and the need for additional equipment or labour. Ground-floor window installations are generally less expensive because they are easily accessible. However, installing windows on upper floors may require scaffolding or specialised equipment, adding to the cost. The complexity and safety measures required for higher installations can significantly impact the final price.

5. Type of Glass: The choice of glass technology influences the cost. Basic double glazing is the most affordable option, but upgrading to advanced glass types, such as solar protection glass that reduces UV light and heat entry, tinted or patterned glass for privacy and aesthetics, or self-cleaning glass, which features a surface coating that reacts with sunlight to break down dirt, can increase the price. These specialised glasses offer additional benefits but come at a premium.

The costs of double-glazed windows reflect the number of windows typically found in houses of various sizes, with a significant jump as the number of windows increases. This is because more windows not only require more materials (glass, frames, and gas for insulation) but also more labour for installation. For instance, the cost for double glazed windows in a 3-bedroom terraced house, which is estimated at £4200, assumes it has around 9 windows. This provides a ballpark figure for homeowners to start budgeting for this valuable home improvement. It’s essential to consider these estimates when inquiring, how much are double glazed windows? as they offer a realistic expectation of the investment needed to enhance a home’s energy efficiency and comfort.

Additional Costs and Considerations

Beyond the basic installation, there are other costs to consider:

Resealing Double-Glazed Windows: Over time, windows may need to be resealed to maintain their efficiency and aesthetics. Costs for resealing can range from £50 to £80 depending on the size of the window.

Double-Glazed Doors: An increasingly popular choice for enhancing home sustainability, double-glazed doors can vary in cost from £625 for basic models to upwards of £1200 for high-end options.
