The UK Fenestration Industry in 2025: What the Data Tells Us

The UK fenestration industry is entering a defining phase. With market consolidation, shifting consumer demands, and energy efficiency pressures all in play, now is the time to reassess your strategy. Insight Data has released its 2025 Fenestration Market Overview – a data-led report helping suppliers, manufacturers, and installers understand the shape of the year ahead.

Key Shifts in the UK Fenestration Sector

The past few years have seen significant change:

• The number of PVCu fabricators has fallen from 1,534 in 2014 to just 1,132 in 2025.
• Aluminium fabricators have risen, reflecting demand for innovative aluminium products.
• Sliding doors and bifold doors remain strong despite a slowdown in overall market volume.

This suggests a polarising market. Premium fab companies are gaining market share while smaller firms struggle. For stakeholders, this creates both risk and opportunity.

Why This Matters for Your Business

The Bank of England predicts a modest economic recovery. That will likely support investment in home improvement, but only for businesses that align with current trends. This includes:

• Prioritising sustainability and reducing waste packaging
• Offering products that improve natural light and energy performance
• Supporting installers with live data and better marketing

Understanding where the fenestration industry is heading gives you a competitive edge. That’s where the 2025 report comes in.

What’s Inside the 2025 Fenestration Market Overview

The report is based on over 20,000 live verification calls per month. It covers:

• Aluminium and uPVC fabricator volumes
• IGU manufacturer numbers
• Frame-per-week volumes by company size

This intelligence lets you see exactly how the market is moving – from factory site activity to installer trends.

Industry Decline or New Opportunity?

Yes, overall volumes have dropped. But that’s not the full picture:

• Fabricator numbers are down, but product range diversification is up
• The rise of specialist aluminium fabricator firms is reshaping supply chains

Rather than decline, this may signal a shift towards a leaner, more responsive fenestration sector.

Why Fabricators and Installers Should Pay Attention

This report offers vital data for:

• Companies looking to target the right installer
• Marketing teams responding to business finances and business behaviour
• Business development teams are identifying new trade partner opportunities
