Dwellings – the contractor will need to undertake remedial work and then commission a re-test on the same unit as well as an additional test on another unit. Testing and re-testing will continue until the tests prove that the performance is satisfactory.
Non-dwellings – the contractor will need to undertake remedial work and commission a further test to confirm that the required performance is achieved.
