Air Tightness Test
What Is Air Tightness Testing?
Air Tightness Testingโalso called Air Pressure Testing or Air Permeability Testingโis a method used to detect and measure unwanted air leaks in a building through gaps, cracks, and openings.
This test reveals where warm air escapes and cold air enters, affecting comfort, energy efficiency, and heating costs. Itโs an essential step in evaluating a buildingโs thermal performance and planning energy-saving improvements.
If your home feels draughty, struggles to stay warm, or suffers from condensation or ventilation problems, air tightness testing can help identify the cause and guide effective solutions.
โ Measures how airtight your property is using professional, industry-standard techniques
โ Helps reduce heat loss, draughts, and energy bills
Why Air Tightness Testing Matters?
Air leaks can significantly impact your homeโs comfort and energy efficiency. Air Tightness Testing identifies hidden gaps where heat escapes, helping you enhance your propertyโs performance before installing insulation or upgrading your heating system.
โ
Lower Energy Bills
Sealing air leaks means your heating system works less, reducing fuel consumption and cutting energy costs.
โ
Boost Comfort & Eliminate Draughts
Testing helps address cold spots, uneven temperatures, and unwanted airflow around windows and doors, making your home more comfortable.
โ
Support Insulation & Retrofit Projects
A well-sealed home ensures insulation and ventilation upgrades are more effective and helps meet PAS 2035 retrofit standards.

How Air Tightness Testing Works?
Blower Door Testing
A calibrated fan is installed in an external door to create pressure and measure air leakage. This highly accurate method identifies draughts and is ideal for planning retrofit work.
Pulse Testing
A quick, non-invasive test using a controlled burst of air at low pressure. Perfect for occupied homes, it delivers fast results under normal living conditions without disruption.
What You Receive
You get a formal air permeability report, clear test results, and expert guidance on how to reduce air leakage and improve your homeโs energy efficiency.

What is Background Ventilation Testing (BVT)?
Background Ventilation Testing (BVT) evaluates whether a property has enough natural airflow to maintain healthy indoor air quality. The test is usually conducted room by room, measuring airflow through features like trickle vents, air bricks, and passive vents.
BVT is particularly important when improving a propertyโs airtightnessโsuch as during insulation or draught-proofingโto ensure moisture, COโ, and stale air can escape effectively. This helps prevent condensation, mould growth, and poor indoor air quality.
In retrofit projects, especially under PAS 2035, BVT is used to:
โ Avoid over-specifying mechanical ventilation systems
โ Confirm that background ventilation is sufficient in existing rooms
When Should You Get an Air Tightness Test?
Timing your air tightness test correctly ensures accurate results and helps you make informed decisions to improve energy efficiency. Tests can be carried out before, during, or after energy upgrades, depending on your goals.
Paired with Background Ventilation Testing (BVT), a well-timed test ensures insulation, ventilation, and heating systems operate efficiently and comply with regulations.
These tests are valuable whether youโre renovating, retrofitting, or completing a new build, helping verify quality and long-term performance.
Ideal Times for Testing:
โ Before installing insulation, ventilation, or new heating systems
โ During retrofit works to monitor ongoing performance
โ After renovations or new builds to meet Part L compliance
