UK households could save an average £220 every year on their energy bills, a total nationwide annual saving of £5.9bn, by improving their insulation.
Ian Rock, author of the just-published Home Insulation Manual, bases this calculation on official Department of Energy and Climate Change and Energy Saving Trust figures (see below).
The Home Insulation Manual is subtitled How to Cut Energy Bills and Make Your Home Warm and Comfortable – a subject that the recent cold weather brings into focus.
Mr Rock, who is accredited by the Royal Institute of Chartered Surveyors, says insulating all currently un-insulated walls and lofts in Britain’s existing housing stock would yield substantial savings.
He said: “Energy prices have rocketed by up to 50% since September 2010, and look set to continue rising for the foreseeable future. But rather than passively relying on ‘top down’ schemes, such as the Green Deal, enormous numbers of UK households have DIY capabilities – and with the right guidance should be able to carry out a wide range of thermal improvement works.
“But there’s a right way and a wrong way to insulate. What’s right for one type of property can be positively damaging for another. And until now much of the available information has been either highly sales-driven, bafflingly complex, or just plain wrong.
“Mobilising Britain’s DIY armies is the key to making millions of homes energy efficient and cheaper to run. And by cutting the cost of labour and contractors’ profit margins, payback periods can be dramatically shortened.”
The Home Insulation Manual is the first book to contain comprehensive step-by-step guidance for treating all types of walls, roofs, floors, windows and doors – and each project comes with a Haynes ‘hammer rating’ showing the required skill levels.
As OFGEM prepare to levy substantial fines on several of the Big Six energy companies, for missing CESP insulation targets, Ian Rock said: “There is a strong case that resources might be better spent arming millions of homeowners and tenants with practical advice on how to cut their fuel bills.”

Facts for Editors
* DECC estimates that 34% of Britain’s 23.5 million homes with lofts have very little or no loft insulation = 8m homes.
* Energy Saving Trust estimates the approximate saving per year as £180
* £180 x 8 million = £ 1,440,000,000 ( £1.44bn)
* DECC estimates that 18.9 million homes in Britain have cavity walls, of which 69% are insulated. Therefore 5.8 million homes with cavity walls are un-insulated
* Energy Saving Trust estimates the approximate saving per year as £140
* £140 x 5.8m = £ 812m (£ 812,000,000)
* DECC estimates that 7.9 million homes (older properties) have solid walls of which only 2% are insulated. So 98% have no wall insulation and about 7.7 million homes with solid walls are un-insulated
* Energy Saving Trust estimates the approximate saving per year at £460 (insulated internally) or £490 (insulated externally), an average saving of £475 * £475 pa x 7.7m = £3,657 million £3.65bn
