London Air tightness Test

Draughts and air leakage in properties is responsible for a lot of lost energy. That’s the reason it’s a requirement for new dwellings to be designed to a specified standard and achieve specific targets of air tightness. We will arrange your air tightness test in or around London. Your sap Assessor will confirm what levels need to be achieved, or possibly a figure could be specified on the building plans. Your Sap Assessor will then let you know what target your test needs to reach compliance. This figure will depend on the construction and also other elements which have gone into the building of the dwelling.

Preparing for the test is an important factor. This will help you gain a pass the very first time, therefore preventing extra costs by having revisits. Your building envelope needs to be in a finished state (in a position to be occupied), i.e. doors, windows (any cladding if applicable) should be fitted.

Water Calculations London

Screen of sap softwareWater calculations are required under Part G of the building regulations. Under this regulation:

Reasonable provision must be made by the installation of fittings and fixed appliances that use water efficiently for the prevention of undue consumption of water.

It also states that the consumption of water per person must not exceed 125 litres per day or in certain cases, 110 litres per day if planning permission was given stating this.

To show the above, you need the water calculations.
