The Future Homes Standard 2025 will tighten Part L building regulations on energy efficiency. Learn how insulation, rendering, and upgrades affect compliance.
What Is the Future Homes Standard 2025?
The Future Homes Standard 2025 is part of the UK government’s plan to cut carbon emissions. It raises the bar on insulation, airtightness, and heating systems for new homes and significant refurbishments. While aimed mainly at new builds, the changes influence extensions, conversions, and upgrades like rendering and external wall insulation across Surrey and beyond.
How Does It Affect Part L Building Regulations?
The Future Homes Standard updates Part L building regulations, which govern conservation of fuel and power. From 2025, U-value targets for walls, roofs, and floors will be stricter, requiring better insulation and airtight detailing. Render and external wall insulation projects will play a bigger role in helping homes comply.
What Changes Should Homeowners Expect?
- Higher insulation standards: External walls will need improved U-values, achievable with external wall insulation combined with modern render systems.
- Airtightness focus: Detailing around windows, doors, and junctions must prevent draughts and cold bridges.
- Low-carbon heating: The standard phases out new gas boilers, favouring heat pumps and other renewable systems.
- Ventilation: With tighter homes, mechanical ventilation and heat recovery (MVHR) may be recommended.
Impact on Extensions and Renovations
If you’re planning an extension, loft conversion, or significant refurbishment in Surrey, your project will need to meet the revised standards. That means demonstrating compliance through updated SAP calculations and proving that insulation, airtightness, and thermal detailing meet new requirements. Early planning with your builder or energy assessor is essential to avoid rework or delays.
Government Support and Grants
To help with costs, the government offers schemes like the Boiler Upgrade Scheme, which supports replacing old boilers with heat pumps. Additional funding streams may become available as the 2025 deadline approaches.
