Air Tightness Testing Cost

Air tightness testing costs are from £195 but can be as much as £790 depending on the location of the property, the size and complexity of the design.

If you have multiple properties that can be tested on the same day, the costs are £195 attendance fee and additional tests can be done at a lower cost. Depending on the volume of properties to be tested there can be a substantial saving.

The fees include all the costs associated with testing, property assessment, certification and lodgement. We are not VAT registered so there will be no additional costs to pay.

What is the cost of a retest if the first test is a fail? If you are able to fix the air leakage within 30 minutes, whilst the tester is there,  then usually there is no cost for a retest. To fix an air leak you simply have to use silicon, caulk or expanding foam which is relatively straight forward. If the tester has to return on a separate day to conduct another air tightness test then additional costs will be incurred but usually less than the cost of the initial test.

What happens if you cancel? Providing you give 24 hours notice before you cancel then there is no charge for cancelling a booking.
