Loft Installation Process
Once the surveyor has approved your property for installation, an approved installer will carry out your loft insulation. The work usually takes 1-2 hours depending on the size of your property.
1. Before the installer can lay insulation, you’ll need to clear
your loft area and leave it unboarded. Access to the loft
may be difficult, in which case remedial work will be carried
out. If this incurs additional costs, these will be quoted at
survey stage.
2. Rolls of mineral wool fibre are laid between and across the
joists (wooden frame) in your roof space, until the depth
reaches the recommended level of 250-270mm (10'').
3. When the weather is cold, you may find the temperature in
the loft can be significantly lower than the rest of your
house. For this reason, we also insulate the loft hatch and
the cold water pipes and tanks to prevent them from
freezing.
4. Your loft needs to breathe so the installer will ensure the
space is sufficiently ventilated.

* Installing these measures will reduce your heating bills and we calculate that this could be as much as £340 a year for a 1940’s 3 bed semi detached home with a ten year old gas boiler and a gas price of 3.407p/kWh. More modern homes save less. Your individual savings depend on a large number of factors and the £340 quoted should be treated as a guide. Also experience tells us that many customers like to have a warmer home, making it more comfortable. This reduces the saving. But even allowing for this, both forms of insulation are a worth-while investment.
