What changes the price
- Number of tests per visit (more tests on one visit lowers cost per test)
- Houses (airborne walls only) vs flats (airborne plus impact on floors)
- Number of dwellings and groups/sample sizes required by Approved Document E
- Travel and site location
- Accredited (UKAS/ANC) tester requirement
- Remedial work and retest after a failure, which is excluded
What a visit usually covers
Firms commonly quote a set of tests for a house (walls only) and a larger set for a block of flats, which includes both airborne and impact tests. A flat conversion with several party walls and floors sits towards the upper end of the range.
How to get a fair quote
- Prices are normally per visit rather than per home, so ask how many tests the price includes. Extra tests on the same visit are usually about £100 each.
- Book early. If a home fails, you pay for a re-test after the remedial work.
- Get at least three quotes for the same job, and compare what each includes as well as the total.
- Check the provider’s accreditation. See how we check listings.
