Future Proof Your Home with Part L-Compliant Windows and Doors

At Alexander Windows, we understand the importance of investing in products that are built to last. With major updates to Part L of the UK Building Regulations coming into effect in 2025, energy efficiency and compliance are at the forefront of every homeowner’s mind. The good news? When you choose Alexander Windows, you can rest assured that our products are already ahead of the curve—fully compliant and designed to meet the new standards with ease.

What Are the Changes to Part L?

Part L of the Building Regulations focuses on reducing carbon emissions and improving energy efficiency in homes. The 2025 updates are part of the UK’s strategy to achieve net-zero carbon emissions by 2050, ensuring homes are warmer, greener, and more cost-effective to run.

Here’s a quick overview of the key changes:

• Stricter U-Values: Windows and doors will need to achieve better insulation, with lower U-values to reduce heat loss significantly.
• Minimum Energy Ratings: Replacement windows and doors must meet a Window Energy Rating (WER) of at least ‘B’ to ensure superior thermal performance.
• Improved Airtightness and Ventilation: Homes will become more airtight to prevent heat loss. To maintain indoor air quality, background ventilation features like trickle vents will also become mandatory.

These changes are great news for homeowners. Not only do they mean lower energy bills and a reduced carbon footprint, but they also ensure that homes stay comfortable and compliant for years to come.
