New Air Tightness Testing Service Launched!

We are delighted to announce that we have today launched a new service – Air Tightness Testing (otherwise known as Air Pressure Testing, or Air Permeability Testing).

Air pressure testing is a requirement of Part L1A  of the Building Regulations for newly built Domestic Properties.

Pressure testing measures the amount of uncontrolled air flow (also known as air leakage) within a property as a result of unsealed gaps or cracks within the thermal envelope.

The Building Regulations contain a maximum permitted threshold for the air pressure test, and the result of the test contributes towards SAP calculations. Air leakage testing default rates or sampling processes can be used, but it can be more cost-effective to carry out individual air pressure tests, the results of which can reduce the overall calculated energy consumption of a building.

The building pressure test result has a direct bearing on the property’s Dwelling Emission Rate (or Building Emission Rate) and therefore it’s overall compliance with Part L.

We offer an accredited testing service approved by BINDT (The British Institute of Non-Destructive Testing) and accepted by Local Authority Building Control Inspectors & Private Approved Inspectors. Our prices are £175 plus VAT for the first (or only) plot to be tested*, and every plot tested on the same site on the same day will be charged at £50 plus VAT. *within 60 miles of NP8 1LP or EX15

As the Air Pressure Testing Results feed directly into your SAP Calculations, having us undertake both results in a more streamlined process – one less thing for you to have to administer.

We can also offer on-site training to key personnel to make them more aware of the requirements and show them (through the use of smoke) where leakage paths commonly occur and how they can be easily rectified for future developments.

If you would like to discuss your requirements or book in a test, please don’t hesitate to call.
