New Build Air Tightness Testing

• All new build/replacement dwellings must undergo an air tightness test on completion to comply with Part L of the UK Building Regulations.

• A pre-completion test can be completed to identify potential air leakage issues prior to the final test.

Existing Properties

• We offer air tightness testing for existing dwellings to assess the scope of proposed retrofit works and evaluate results post-completion.

• We can provide a detailed report with clear recommendations for draught-proofing and guidance on remedial work to improve airtightness and overall thermal performance.
