Air pressure testing is a vital method for assessing the airtightness of a building. By measuring the air leakage rate, we can determine how effectively a building is sealed from external elements – helping to:
✔️ Improve energy efficiency
✔️ Enhance indoor comfort and air quality
✔️ Ensure compliance with building regulations
✔️ Reduce utility costs and carbon footprint
We work with contractors, developers, and architects to:
• Ensure compliance with Part L and industry standards
• Identify leakage paths before they become costly issues
• Support smoother handovers and reduce project delays
Why is this important for EPCs? 🔍
When no air pressure test is carried out, EPC assessors must use default SBEM/ SAP figures in line with EPC Conventions, which often do not reflect the true performance of the building. At LP Energy, we strongly recommend air pressure testing to ensure an accurate energy model, a stronger EPC rating, and a more sustainable building overall.
With the recent change in RDSAP to RDSAP 10, we now have the capabilities to air test existing properties as part of upgrade projects and to assist with landlords who are aiming to meet with MEES compliance.
Our reports are clear, actionable, and designed to help you hit airtightness targets with confidence.
If your next project requires testing, we’d be glad to support you.
