uPVC Double Glazed Windows

Why choose uPVC double glazing?

Modern uPVC windows deliver exceptional thermal performance, achieving A-rated energy efficiency to keep your home warmer and reduce heating bills. With advanced multi-chambered profiles and high-performance sealed units, today's double glazing can save you hundreds of pounds per year compared to older single-glazed or early double-glazed windows.

A typical 3-bedroom home costs around £4,000–£8,500 for a complete uPVC window replacement in 2026. Unlike timber frames, uPVC requires virtually no maintenance — no painting, no staining. A simple wipe-down keeps them looking pristine for 20–30 years.

Energy efficiency and U-values explained

Energy performance in windows is measured by U-value — the lower the number, the less heat escapes. Our A-rated windows achieve U-values as low as 1.2 W/m²K, compared to 4.8 W/m²K for single glazing and 2.8–3.0 W/m²K for early 1990s double glazing.

In practical terms, replacing old single-glazed windows with modern A-rated double glazing in a typical 3-bed semi saves £100–£200 per year on heating bills. Upgrading from older double glazing saves £60–£120 per year. Over a 25-year lifespan, that's £1,500–£5,000 in energy savings — and all energy-efficient window installations qualify for 0% VAT.

• A-rated windows: U-value 1.2–1.4 W/m²K — meets and exceeds Building Regulations (Part L)
• Triple glazing available: U-value as low as 0.8 W/m²K — ideal for exposed or north-facing elevations
• Argon gas-filled sealed units reduce heat transfer by 30% compared to air-filled
• Low-emissivity (Low-E) glass reflects heat back into the room while letting light through
• Warm-edge spacer bars reduce condensation and cold spots at the glass edge

Noise reduction: how it works

Our "up to 50% quieter" claim is based on the acoustic performance of sealed double-glazed units with 28mm overall thickness (4mm glass / 20mm argon gap / 4mm glass). This configuration achieves a sound reduction of approximately 30–35 dB, compared to around 20–22 dB for single glazing — a reduction that the human ear perceives as roughly halving the volume of external noise.

For homes on busy roads, near railways, or under flight paths, we offer enhanced acoustic glazing with asymmetric glass (e.g. 6mm outer / 16mm gap / 4mm inner) or laminated glass, achieving up to 40 dB sound reduction. This makes a dramatic difference to comfort and sleep quality.

A style for every home

We offer a comprehensive range of window styles to complement any property, from period terraces to modern new-builds. Every window is available in a wide selection of colours and finishes.

• Casement windows — the UK's most popular style, from £300 per window, with over 70 configurations
• Bay & bow windows — create space, light, and stunning kerb appeal (from £1,000)
• Flush fit windows — authentic timber look for period and conservation area homes
• Tilt & turn windows — versatile ventilation, ideal for upper floors (from £490)
• Vertical sliding sash — heritage styling with modern A-rated performance (from £520)

Range of finishes and colours

Your new windows no longer have to be just white. Choose from a wide range of colours and woodgrain finishes to complete your look — from classic cream and anthracite grey to authentic oak and rosewood effects. Dual-colour options let you choose different colours for inside and outside.

All our colour options are available across the full window and door range, so you can create a beautifully coordinated look throughout your home. Colour-bonded profiles won't fade, peel, or require repainting.

Could you get funding for new windows?

If your household income is under £32,000 and you own your home in Greater Manchester or Lancashire, you may qualify for up to £2,000 towards window replacements through the Local Residents Scheme. The scheme covers draughty, damaged, or single-glazed windows — exactly the kind of upgrades that improve comfort and cut energy bills.

We handle the paperwork and coordinate the installation, so there's no hassle on your end. Check your eligibility in under a minute.

Frequently asked questions

Common questions about window replacement:

• How long does installation take? — A single window takes 1–2 hours. A full house (8–12 windows) is typically completed in 2–3 days. We fit one window at a time, so your home is never open to the elements
• Do I need planning permission? — No, for standard window replacements. If you live in a conservation area or listed building, you may need approval — particularly for changes to the front elevation or window style. Flush fit and sliding sash designs are often accepted in heritage settings
• What's the difference between A-rated and C-rated windows? — A-rated windows have a U-value of 1.2–1.4 W/m²K and use Low-E glass with argon gas. C-rated windows (U-value ~1.8 W/m²K) use standard glass and air-filled units. The cost difference is typically £20–£40 per window, but A-rated saves more on heating long term
• What happens to my old windows? — We remove and responsibly dispose of all old frames and glass. uPVC is recycled wherever possible
• Do you offer triple glazing? — Yes. Triple glazing achieves U-values as low as 0.8 W/m²K and provides superior noise reduction. It costs roughly 20–30% more than double glazing and is ideal for exposed or north-facing walls
• Are your installations FENSA registered? — Yes. Every installation is FENSA certified, which means it's automatically notified to your local council's building control department. You receive a certificate for your records — important for future property sales

Sustainability built in

We're committed to reducing environmental impact. Our window profiles incorporate recycled materials and are themselves fully recyclable at end of life. Choosing energy-efficient A-rated windows also reduces your household's carbon emissions — a smart choice for both your home and the planet.
