AIR TIGHTNESS TESTING

Get 3 FREE quotes from accredited installers.

Tests for air leakage in buildings as air leakage can account for a considerable percentage of heat loss. Up to 20% of the heating bill can be saved by simply sealing up the holes of the building.

Air tightness testing, also known as a blower door test, measures how much air escapes through gaps and cracks in a building’s envelope. It’s a key part of energy efficiency assessments and is often required for new builds or major renovations.

How Does It Work?

A temporary fan is fitted into an external door to pressurize or depressurize the building.
Sensors then measure how much air is leaking.
The results help identify problem areas where insulation or sealing can be improved.

Why It Matters?

  • Reduces heat loss and energy waste
  • Improves indoor comfort
  • Supports compliance with Part L of Building Regulations
  • Essential for achieving high energy ratings (BER, EPC, etc.)
  • Helps future-proof buildings against energy price rises

Who Needs It?

  • New residential and commercial buildings
  • Retrofit and renovation projects
  • Developers aiming for low-energy or passive house standards
  • Anyone applying for BER or EPC certification
