Key Insight: The UK window and glazing market continues to evolve rapidly, driven by energy efficiency demands, technological innovation, and regulatory changes.
With over 93% of UK homes now featuring double glazing and composite doors dominating over 50% of the entrance door market, the sector is poised for transformative growth alongside sustainability initiatives.
Key Statistics for the UK Window Industry in 2025
- Market Valuation: The UK windows and doors market is projected to surpass £3.5 billion by 2030, growing at a 5.3% CAGR. Metal door and window manufacturing alone accounts for £2.6 billion in 2025.
- Material Trends: uPVC holds 75% of the window market, but aluminium frames are rising due to slimline designs and durability. Composite doors now represent 50% of entrance door sales.
- Energy Efficiency: Double glazing reduces heat loss by up to 60%, saving detached households £120–£155 annually. Triple glazing adoption is accelerating, with a U-value of 0.8 W/m²K becoming the new benchmark.
- Market Players: 2,990 glazing businesses operate in the UK, with industry revenue growing modestly at 0.1% CAGR since 2019.
Market Trends Shaping 2025
1. Energy Efficiency Dominates Consumer Choices
With 35% of residential energy lost through windows, demand for low-emissivity (Low-E) coatings and argon-filled triple glazing has surged. The average U-value for new installations now sits at 1.3 W/m²K, down from 1.6 in 2020. Sheerwater Glass reports a 40% increase in inquiries for these products, reflecting stricter building regulations under the Future Homes Standard 2025.
2. Smart Technology Integration
Modern installations now feature integrated sensors for thermal monitoring and self-tinting electrochromic glass, which adjusts opacity based on sunlight. Over 25% of high-end conservatories include automated climate control systems, including warm roofs, solar controlled glass and low-E glazing, a area Sheerwater Glass specialises in.
3. Aluminium’s Resurgence
Though uPVC remains dominant, aluminium frames now constitute 18% of new installations—up from 12% in 2020—due to sleek aesthetics and compatibility with panoramic glazing. Guildford based projects by Sheerwater Glass show a 30% preference for aluminium in luxury home renovations.
4. Composite Doors Redefine Security
Composite doors, combining GRP skins with insulated cores, now dominate 50% of the UK entrance door market. With multi-point locking systems and 35-year warranties, they may offer a longer lifespan than traditional timber.

- Conservatories: Average £15,000+, boosting property values by 5–15%.
Technological Innovations
Materials Revolution
- Vacuum Glazing: Slimmer than triple glazing with a U-value of 0.5 W/m²K, though costs remain prohibitive (£200/m²).
- Self-Healing Glass: Nanoparticle coatings repair minor scratches, emerging in premium markets.
Sustainable Practices
- Recycled Materials: 70% of uPVC frames now use recycled content, reducing carbon footprints by 40%.
- Solar Glazing: Building-integrated PV windows generate 30W/m², piloted in Surrey homes.
Environmental Impact
- CO2 Reduction: Upgrading to double glazing cuts 4 tonnes of CO2/household annually—equivalent to 1.5 petrol cars.
- Circular Economy: 80% of window components are recyclable, with 2030 targets set at 95%.
Challenges and Solutions
Supply Chain Pressures
