INSULATION &
ENERGY EFFICIENCY

Global warming, CO2 emissions, rising fuel prices and ozone depletion are now topics of constant discussion, as we become more concerned to restrict energy losses and protect our environment.

Insulation standards in new housing stock have improved dramatically in the last few decades (largely through The Building Regulations) but surveyors rarely come across older properties which are insulated to their best advantage, and in many cases, money is literally being burnt!

Heat is lost from property in various ways - through the roof (about 25%), the main walls (about 35%), windows and doors (25%), floors (l5%).

It is important for homeowners to consider the relative cost of carrying out improvements compared with the likely savings - in other words there is normally a "pay-back" period. The following table provides an indication of the approximate savings, which can be achieved (for a basic type of property)

Pay Back Period

• Cavity Wall Insulation 4-5 years
• Loft Insulation 2-3 years
• Hot Water Cylinder Insulation 3 months
• Draught proofing 3 years
• Replacement High Efficiency Boiler 10-20 years

These approximate pay-back periods may well be reduced if a property has already been partly improved by upgrading insulation. Also, grant aid is available for some types of insulation making improvements a more attractive proposition and uptodate information can be obtained from environmental departments in local authorities and other Government sources.

• Energy Saving Trust
• Building Research Establishment

• The Cheshire Energy Efficiency Advice Centre is another useful source of information 0800 512 012.

Home owners can commission a standard assessment procedure (SAP) report on residential property at the same time as a survey or mortgage valuation. This report provides an energy rating assessment together with advice to upgrade insulation standards to achieve greater fuel efficiency.
