uPVC Windows

Why Choose to change your excising windows?

Modern A-rated uPVC windows represent the gold standard in energy-efficient glazing. Independently tested and certified under the British Fenestration Rating Council (BFERC) system, an A rating (now transitioning to A++ under the latest standards) means your windows achieve the highest possible level of thermal performance, security, and durability.

Switching from old timber, aluminium, or even outdated double glazing to A-rated uPVC windows delivers immediate and long-lasting benefits to any property – whether it’s a period home, 1930s semi, new-build or flat.

1. Dramatic Energy Savings & Lower Bills

A-rated uPVC windows use advanced multi-chamber profiles, warm-edge spacer bars and low-emissivity (Low-E) glass filled with argon gas. This combination can achieve U-values as low as 1.0–1.2 W/m²K (compared to 5.0+ for single glazing or 2.0–2.8 for older double glazing).

Real-world impact:

• Reduce heat loss through windows by up to 70%
• Cut annual heating bills by £150–£300+ (Energy Saving Trust figures)
• Achieve payback on your investment in as little as 5–8 years through energy savings alone.

2. A Warmer, More Comfortable Home All Year Round.

Say goodbye to cold draughts, condensation on glass and single-glazing “cold spots”. A-rated windows keep rooms warmer in winter and cooler in summer by reflecting heat back into the room and blocking excessive solar gain.

• No more icy patches near windows in winter
• Reduced internal condensation and risk of black mould
• Even room temperatures – less reliance on heating in colder months

3. Significantly Improved Sound Insulation.

The thick, multi-chamber frames combined with laminated or acoustic glass options can reduce external noise by up to 45 dB – perfect if you live near a busy road, railway or flight path.

Turn a noisy house into a peaceful retreat.

4. Enhanced Security as Standard

Every A-rated uPVC window we supply includes:

• Multi-point locking systems
• Internally beaded frames (preventing glass removal from outside)
• Toughened or laminated safety glass
• Option to have Yale SensCheck window hardware read more on this in our services page labelled Yale SensCheck.

5. Virtually Zero Maintenance & 10-Year Guarantees.

Unlike timber that rots and needs repainting every few years, uPVC is:

• Fade-resistant and colour-fast (won’t yellow or flake)
• Simply wiped clean with a damp cloth
• Backed by comprehensive 10-year insurance-backed guarantees
• We are also a CERTASS improved installer providing self certification 

6. Increase Your Property’s Value & Market Appeal.

Estate agents consistently report that modern double glazing is one of the top features buyers look for. A-rated windows:

• Boost Energy Performance Certificate (EPC) ratings (often moving a home from D/E to B/C)
• Make your property more attractive to buyers
• Add genuine kerb appeal with slim, elegant sightlines and a range of finishes (white, woodgrain, anthracite grey, chartwell green, black, cream and more)

7. Eco-Friendly & Sustainable.

Lower energy consumption = lower carbon footprint. Many of our uPVC profiles contain recycled material and are 100% recyclable at the end of their very long life (typically 35–50 years).

Start Enjoying the Benefits Today.

Upgrading to A-rated uPVC windows is one of the most cost-effective home improvements you can make. You’ll notice the difference from the very first winter – warmer rooms, quieter living, smaller bills and a home that looks and feels brand new.
