Leeds - Air Testing - 0113 850 0152

We offer air testing throughout Leeds and surrounding areas - our experienced assessors will be happy to offer advice on the best ways to gain your target rating.

It's important to find a reliable air testing company in Leeds early on as they can tell you how many tests you'll need to undertake per property and agree with Building Control a testing regime. Our consultants are more than capable of undertaking such tests and planning a testing schedule that's both efficient, cost-effective and won't intrude on or hinder other workers you may have on site.

When should an air test be carried out?

Once all elements of a building are sealed and the building envelope is completed (towards the end of the build process) is when an air test is usually undertaken. An air test will provide an air permeability rating that resembles the amount of uncontrolled air that's leaking from the dwelling.

The number of properties to be tested should be in accordance with the following table.

Our accredited consultants 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%

We have expert consultants that 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.

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.

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.

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

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