What we inspect
The living area of the property must be able to reach 18 degrees with a qualifying heater.
We collect information on your living area such as
Exterior and interior wall sizes
Existing heating source (If applicable)
We then use all this information in our data audit and calculation process
This has probably already been done!
However this standard requires a minimum of 120mm of insulation.
This is more than the 70mm required as at 1st July 2019.
In short, if you had insulation recently installed chances are that you will already be compliant.
If you haven't we will give you an up-to-date insulation statement.
We also inspect insulation to get data which affects our heating calculation.
Each habitable space must be externally vented,
ie: an openable window in each bedroom
The area of the openable window must equal at least 5% of the total floor plan area of that room.
However it is recognised if there are other methods employed to ventilate the room, such as a home ventilation system.
An extractor fan is now required in all bathrooms and kitchens.
We collect data on existing fans to check whether or not they comply with the new regulations, a process which may require the use of an anemometer.
We will check the property for any significant draughts. Draughts can be caused by gaps, holes and damage etc.
Information is recorded in respect of each potential draught. This information is then reviewed in our auditing and report process.
It is then decided if the property has significant draughts which will negatively affect the heating of the house.
Moisture Ingress and Drainage
We inspect the exterior of the house for any evidence of storm water issues, surface water issues and/or drainage problems. From this information a report is drawn up.
Ground Vapor Barrier
All properties that have an enclosed sub-floor will require a ground vapor barrier. The purpose of this is to prevent moisture rising from the sub floor area.
