Save money with home insulation

Installing insulation, removing draughts and turning down your thermostat will conserve energy and your bank balance.

Ways to insulate

Insulating your home as much as possible is a great way to minimise heat loss and save cash.

Loft insulation

Energy costs literally go through the roof if your loft isn’t insulated – a quarter of your heating disappears that way. Insulation traps warm air rising up through the house, lowering your heating bill by around £205 a year.

Walls

Cavity wall insulation reduces heat loss from your home by a third, saving you about £160 annually. Solid wall insulation (recommended for pre-1920 properties) gives you a saving of up to £500.

Floors

Laying mineral wool insulation can save you £50 a year on heating.

Hot water cylinder

Treating your cylinder to a new insulation ‘jacket’ can cut heat loss by more than 75% – and take up to £40 off your energy bill.

Pipes

Insulate your hot water pipes for a handy little saving of £10 a year.

Heat-saving hints

Conserving energy means more than just using insulation – changing your heating habits and banishing draughts are key cash-savers too.

Turn your heating down by just 1°C

This saves you around £60 a year on heating.

Close your curtains

Hang thick curtains and always close them at dusk – another simple way to keep the heat in.

Eliminate draughts

You lose up to one-fifth of your home’s heat just through gaps around doors, windows and letterboxes – but don’t worry, it’s easy to fix. Use fillers, sealant and tape from DIY shops to plug those gaps and save £30 on heating every year.

Fit double glazing

This will slash the amount of heat you lose through windows by half and could take about £140 off your annual bill.

Get a new boiler

Installing a high-efficiency boiler (from £400, depending on your home size) cuts an annual heating bill by £275.
