Leicestershire - Air Testing - 0116 356 0136

Our air testing consultants offer constructive advice on the best way to reach your target rating.

A dwelling in Leicestershire must receive an air permeability result of 10 m³/(h.m²) to successfully pass an air leakage test in England and Wales. However, in the design stage SAP, the APR will often produce a more accurate and realistic target.

Should your test fail, the dwelling may need re-testing following some potentially costly revisions - that's why it's always a good idea to seek advice early. To restore confidence with Leicestershire Building Control, you may also need to test further properties in your group.

We provide air testing for Leicestershire - stated on the table below are the number of air tests you may require.

We have professional, accredited consultants who can help you comply with EPBD Article 9 and the Energy Performance of Buildings Regulations.

No. of Dwelling Type Instances No. of Tests Per Type
4 or less One test of each type
Greater than 4, but equal or less than 40 Two tests of each type
More than 40 At least 5% of each type, unless the first 5 units pass, when the frequency can be reduced to 2%

Our expert consultants will undertake an assessment of the efficiency of your air conditioning system, reviewing sizing / capacity and offering advice on any improvements or alternative solutions. These solutions, if implemented, can in many instances reduce costs and thus pays for the inspection in the first year.

It is a requirement under the Building Regulations 2006 Part L that new dwellings in Leicestershire must pass an air test prior to occupation; this test certificate must be produced for the dwelling to be signed off by local Leicestershire building control.

The report has all the details required by the regulations to indicate that a valid test has been performed.

To carry out such a test with accurate results, we require some general requirements to be made available at the time of the test: SAP Design air pressure test figure, an electricity supply and a water supply to enable traps to be filled.

We will seal all of the intentional leakage areas in the house prior to testing. These include:

  • Fireplaces
  • Extractor fans
  • Exhaust fans
  • Trickle vents
  • The odd uninstalled component

Everything else will have to stay 'as is' in the property.
