Ramsgate - Air Testing - 020 3390 0301

In Ramsgate our air testing consultants will offer constructive advice on how to reach your target rating.

Prior to a test being carried out all ventilation systems must be switched off and sealed to the outside to avoid unnecessary air loss that can disrupt the results. Drainage taps, such as a toilet bowl, should be filled with water as air can also escape down here where it normally wouldn't when the property is complete. Other areas such as letter boxes, key holes, cat flaps and loft hatches should not be sealed as these will remain "open" when occupied.

What's involved in an Air Test in Ramsgate?

An air test involves placing a large fan, or several fans, to an opening within the property; usually a doorway. The fans will increase and decrease in speed that will in turn change the building's air pressure and record the results. An air test cannot be carried out if wind speed is more than 13mph; 3 metres per second is the ideal wind speed when undertaking an air test in Ramsgate.

The table below shows the number of air tests you may require./p>

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.

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

To carry out such a test with accurate results, we need some general requirements to be made available at the time of the test:

  • SAP Design air pressure test figure
  • An electricity supply
  • A water supply to enable traps to be filled

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

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.
