As a member of ATTMA, the appointed air pressure testing organisation for the BINDT, BSRIA is a fully accredited testing body, guaranteeing certificates will be recognised by your building control officer.
Airtightness testing of new dwellings is now mandatory for developments of over two units in England and Wales. A sample of each type of dwelling must be tested and be within the air leakage rate stated in the dwelling's SAP calculations.
For one or two units, airtightness testing is not mandatory, but an 'assumed' air leakage rate above the industry norm must be made. Often, it is simpler and more cost-effective for builders to test to prove a lower air leakage rate than to find more complex ways to demonstrate energy saving.
We will provide a free testing regime, calculating how many of each type of dwelling will need to be tested. From your build plan, we can also help you decide when testing will be most cost effective and keep site disruption to a minimum.
