Average costs of secondary window glazing

Secondary glazing involves adding an extra pane of glass or acrylic to existing windows. It’s a cost-effective way for you to improve thermal and acoustic insulation. Prices vary based on factors such as window size, glazing material, and customisation needs, with costs ranging from £200 to £700 per metre squared. On average, you should budget as follows:

Secondary Glazing Job	Price Range
Standard window	£200–£350 per m²
Large window	£350–£500 per m²
Custom size/shape	£500–£700 per m²

Acrylic glazing

Acrylic glazing is the more cost-effective and lightweight choice, with prices typically ranging from £150 to £250 per square metre. The installation process for acrylic glazing is relatively swift, usually taking between 1 to 2 hours per window. The advantages of opting for acrylic include its affordability and the straightforward nature of its installation. However, it's essential for you to weigh these benefits against the drawbacks, such as decreased durability and reduced noise insulation compared to glass.

Glass glazing

Glass glazing has superior noise reduction and thermal insulation qualities. You can expect the cost of glass glazing to fall within the range of £200 to £400 per square metre, with installation taking 2 to 3 hours per window. Glass glazing is more energy efficient and more durable, yet it weighs more and comes at a higher price point.

Additional costs

Beyond the initial outlay for the secondary glazing materials and their installation, you should also consider potential additional costs. These can include potential adjustments to electricals, repair or removal of existing window frames, and finishing touches such as decorating around the newly installed glazing. Each of these factors can contribute to your overall cost.

Potential Additional Work	Cost
Electrical adjustments	£50–£150
Frame repair/removal	£100–£300 per m2
Decorating	£150–£400

How long does secondary glazing take?

You can expect installation of secondary glazing to take 1–4 hours per window:

• Standard windows: Installation typically takes 1–2 hours per window
• Large or custom windows: May require 2–4 hours per window due to additional measurements and custom fittings

A professional team can install secondary glazing for an entire home within 1–3 days, depending on the number and type of windows.

How to reduce secondary glazing costs

You can reduce the costs of secondary glazing in your home, without sacrificing efficiency or safety. Here are our price-reducing tips. Compare quotes: Gathering quotes from several providers ensures you receive a competitive price for your secondary glazing. This practice allows you to understand the market rate and identify good value for your investment. Always ensure the quotes cover similar scopes of work for an accurate comparison.

DIY measurements: By measuring your windows yourself, you can potentially save on the costs associated with professional measurement services. However, it's crucial to double-check your measurements or consult with a tradesperson to avoid costly errors. Incorrect measurements can lead to purchasing the wrong size glazing, incurring additional expenses.

Bulk orders: If you're planning to install secondary glazing on multiple windows, inquire about bulk order discounts. Suppliers often offer reduced rates for larger orders, leading to significant savings. This approach is particularly cost-effective for larger projects or when upgrading glazing across several properties.

Seasonal deals: Many installers and suppliers offer discounts during their quieter periods. Keep an eye out for seasonal promotions or off-peak discounts, which can substantially lower the cost of your secondary glazing project. Planning your project to coincide with these times can offer financial benefits.

Reuse existing frames: If your existing window frames are in good condition, consider secondary glazing solutions that can utilise them. This can significantly reduce material costs and simplify installation. Ensure the compatibility of your frames with secondary glazing panels to make the most of this cost-saving tip.

Opt for simpler designs: Choosing straightforward, less complex glazing designs can also help reduce costs. Intricate designs or custom shapes often come at a premium, so opting for standard sizes and models can lead to savings. Evaluate your needs to see if a simpler design meets your requirements for insulation and noise reduction.

Self-installation: If you’re handy and confident in your DIY skills, self-installing secondary glazing may enable you to make substantial savings on labour costs. Many suppliers offer DIY kits complete with instructions. However, ensure you're fully equipped to handle the installation to avoid any mishaps that could incur additional costs.

Seek energy efficiency grants: Investigate if there are any local grants or financial assistance programs available for energy efficiency improvements that include secondary glazing. These programs can help offset the costs and make your project more affordable. Eligibility varies, so research the requirements and application process thoroughly.

Your secondary glazing cost checklist

Use this checklist to make sure you’re ready to get started on your secondary glazing project.

• Research options: Acrylic and glass options offer different benefits in terms of insulation and noise reduction. Consider the specific needs of your property, such as thermal efficiency or soundproofing. Explore the pros and cons of removable versus fixed units.
• Measure windows: Accurate measurements are essential for a good fit and optimal performance. If unsure, hire a tradesperson. Even slight inaccuracies can lead to draughts or reduced sound insulation. Taking your own measurements? Double-check them to ensure accuracy before ordering.
• Compare quotes: Getting multiple quotes allows you to compare prices and services offered by different companies. It also gives you leverage to negotiate better deals. Be cautious of quotes that seem too good to be true; they often are.
• Check feedback: Feedback from previous customers can provide insight into the installer’s dependability and quality of work. Look for comments on both the product and customer service. Pay attention to how installers handle complaints and resolve issues. Don't hesitate to ask for references or examples of previous work.
• Discuss needs: Communicate your specific requirements, such as reducing noise from a busy road or improving thermal efficiency. An installer will offer tailored advice based on your priorities and your property's characteristics. Ensure the installer is aware of any unique features of your windows that may affect the installation.
• Consider a warranty: A reputable installer should offer a warranty that covers both materials and labour. Ask about the warranty length and what it includes. Understand the process for making a claim, should you need to. Warranties can vary, so compare the terms offered by different providers.
• Plan for installation: Clear the area around windows to provide easy access for the installers. Consider covering furniture to protect against dust. Discuss with the installer how long the process will take, so you can plan accordingly. Ensure pets and children are kept away from the work area for their safety and to avoid delays.
• Budget appropriately: Ensure you have a clear understanding of all costs involved, not just the initial quote. Consider potential additional costs, such as repairing any damage or redecoration after installation. Set aside a contingency fund for unexpected expenses.
