This guide will walk you through everything you need to know—from material options and installation costs to ways you can save money along the way. By the end, you’ll feel confident about planning your budget and choosing the right windows for your home.
Why Double Glazing Is Worth the Investment
Double glazing has become a standard feature in most modern homes, and for good reason. Here’s why it’s worth considering:
- Save on Energy Bills
Heat escapes through windows more than any other part of your home, and single-glazed windows are notoriously bad at keeping warmth inside. With double glazing, you could save as much as £145 a year on energy bills, depending on the size of your property and the windows you replace. - A Quieter Home
Whether it’s traffic, aeroplanes, or noisy neighbours, double glazing helps block out external sounds, creating a peaceful environment inside. - Boost Your Property’s Value
Buyers love energy-efficient, low-maintenance homes. Double glazing is often a key selling point that can increase your home’s market appeal and price. - Improved Security
Double-glazed windows are harder to break than single panes, particularly if you opt for toughened or laminated glass. Add advanced locking systems, and you’ve got a much safer home.
What Affects the Cost of Double Glazing?
The price of double glazing varies significantly depending on several factors. Let’s break it down.
1. Material Types
- uPVC: Affordable, low-maintenance, and widely available. It’s the go-to choice for most homeowners, with prices ranging from £300 to £1,200 per window.
- Aluminium: Sleek and modern but more expensive. Expect to pay £500 to £1,500 per window. However, aluminium frames last longer and require little maintenance.
- Timber: Ideal for period properties, timber frames offer a classic aesthetic but come at a premium, costing £900 to £2,700 per window. They also need regular upkeep to prevent rot.
2. Window Styles
The style of window you choose will influence the cost:
- Casement Windows: A popular and relatively affordable option, costing between £300 and £800 per window.
- Sash Windows: Perfect for older or more traditional homes. These are more expensive, with prices ranging from £500 to £1,500 each.
- Tilt-and-Turn Windows: Practical and versatile, ideal for ventilation. Prices are around £400 to £900 per window.
- Bay or Bow Windows: Large, decorative windows cost significantly more, starting at £1,000 and going up to £3,000 depending on size.
3. Glass Types
- Standard Glass: Basic double glazing, usually included in most quotes.
- Low-Emissivity (Low-E) Glass: Reflects heat back into your home, improving insulation. This adds around £20–£50 per window.
- Toughened or Laminated Glass: Offers extra security and durability, costing about £100–£150 extra per window.
4. Complexity of Installation
Installing new double glazing in an existing frame is quicker and cheaper than replacing the entire unit. Custom or irregularly shaped windows, however, will cost more due to the bespoke work required.
5. Where You Live
Labour and material costs vary across the UK. Homeowners in London and the South East often pay a premium compared to those in the North or Scotland.
6. Additional Features
Upgrades such as decorative finishes, triple glazing, or advanced locking mechanisms can add £50 to £500 per window.

Tips to Save Money on Double Glazing
- Shop Around
Don’t settle for the first quote. Get at least three quotes from reputable installers to compare prices and services. - Consider Government Grants
Check if you’re eligible for schemes like ECO+ that offer funding for energy-efficient home improvements. - Opt for Standard Designs
Custom windows are beautiful but come with a hefty price tag. Stick to standard sizes and designs if you’re on a budget. - Time Your Purchase
Install during the quieter months when demand is lower, as some companies may offer discounts to fill their schedules.
Maintenance and Lifespan
Maintenance Requirements
- uPVC: Simply wipe down with soapy water to keep it looking new.
- Aluminium: Occasionally clean and polish the frames.
- Timber: Requires regular sanding, painting, or varnishing to prevent decay.
Lifespan
With proper care, most double-glazed windows will last between 20 and 35 years. Aluminium frames tend to outlast uPVC, while timber’s longevity depends on maintenance.
Environmental Benefits
Installing double glazing isn’t just good for your wallet; it’s good for the planet too. By improving insulation and reducing energy use, you’re cutting down on your home’s carbon footprint. If sustainability is a priority, consider recycled aluminium or FSC-certified timber frames.
