As part of Energy Saving Week, surveyors in a fleet of 23 cars are going around the country taking thermal images of homes. The initiative, sponsored by the Energy Retail Association, is adopting a door-to-door approach. It offers homeowners a thermal image of their property and advice on what can be done to reduce carbon emissions and potentially save on energy costs.
This saving could prove to be considerable. In a recent survey by B&Q more than three quarters of respondents said that they would prefer to live in a period property than a modern one despite it leaking heat, CO2 and money.
If you are not fortunate enough to come across one of these cars, then B&Q has some handy hints for you - depending on the age of your property. Understanding what period your home belongs to will help you to understand what energy-efficiency measures you may need to take.
Homes built before 1919
About 20 per cent of UK homes were built before 1919. All tend to have solid-wall construction, so cavity wall insulation is not possible. But you can insulate the loft. These homes are often over-ventilated, so draught-proofing is one of the best ways to reduce heat loss. Look at windows, doors and even letterboxes and cat flaps.
Homes built 1919-44
About 19 per cent of UK homes were built in this period. Most have cavity walls and are suitable for insulation. This is one of the most cost-effective measures for energy efficiency that you can make. Again, loft insulation is relevant. Watch out for draughts through the floors, particularly around skirting boards.
Homes built 1945-64
This was the era of the “new town”. There will most likely be cavities between the outside walls, so insulation here and in the roof will reduce heating costs. A mineral wool quilt under wooden floors is best for draught-proofing these properties.
Homes built 1965-84
The 1970s popularised larger homes with mass-produced double-glazing. Many properties will have loft insulation and only some will need cavity insulation. The best way to prevent draughts in these properties is to insulate solid floors using polystyrene, phenolic foam or cork with chipboard.
Homes built since 1985
With construction regulations and vast improvement in building materials, houses are now much more energy efficient. Lofts should have insulation and cavity wall insulation will not be required. For draught-proofing remember to fit underlay beneath carpets or laminate flooring to reduce heat loss.
