Heating and hot water accounts for around 80% of a households total energy bill, so don't let it go to waste! Insulating your loft and walls can dramatically reduce your heat loss and make your home feel warmer and more comfortable, whilst saving you up to £365 per year compared to an un insulated house. Grants are available to everyone for this, regardless of income or age. Those over 70 or in receipt of income or disability related benefits are entitled to free insulation, and everyone else can get funding for around 50% of the cost. Contact the Energy Saving Trust advice centre on 0800 512 012 to find out what you are eligible for.
As well as insulating your home you can cut heat loss by draught proofing your windows and doors wherever you feel cold air coming in. If you have a separate hot water tank this should be lagged with either spray foam insulation or a hot water tank jacket. These jackets cost around £15 and can save you up to £35 per year! Insulating the pipes around your home to stop heat being lost can save you a further £10 - £15 per year.
Older, single glazed windows can let the warmth escape, but changing windows can be an expensive improvement to make. If you are unable to upgrade your glazing, why not buy heavier curtains, or invest in a foil backed roller blind. Research suggests some of these alternatives can do almost as good a job as a double glazed unit, and for a fraction of the cost!
