Services - Acoustic testing

Build Check provide a UKAS accredited Pre-completion Sound Insulation
Testing service as a means of demonstrating compliance with Approved Document Part E.

Testing is performed on properties at the same stage of completion as Airtightness testing. We are therefore able to offer a “one stop shop” with respect to Pre-completion and Airtightness testing.

Following completion of the tests, a detailed report is produced for submission to Building Control or IA/Insurance company. Accreditation by UKAS ensures our testing and reports are fully compliant with the regulations.

The requirement of Approved Document E can be summarised as follows:

• The type of tests required will depend on the type of dwelling. If there are both party walls and floors, a ‘set’ would involve six separate tests to establish the airborne wall performance between two pairs of rooms and both airborne and impact performance of the floors between two pairs of rooms. Although we provide guidance, the selection of rooms to test would be at the discretion of Building Control.


• The regulations require a sample of 10% of the properties in each development to be tested, but this is to be sub-grouped according to construction type. 10% of each type of dwelling on each site should be tested to demonstrate compliance, or otherwise, to Building Control.


• If there are any test failures, then a higher proportion will need to be tested.

For testing to take place:

• We require a complete set of GA drawings including details of construction.
• The building needs to be completed with windows, doors etc. fitted.
• Tests should be conducted in completed but unfurnished, uncarpeted rooms.
• Ensure that the floor, wall and ceilings perimeters and service ducts/boxing are fully complete/sealed.
• Only “quiet” trades can continue to work in the building during testing.
• The test equipment is powered using a standard 240V power supply, which must be available for use in each room to be tested.
• The client may wish to provide a suitable responsible person to witness the test.
