Click one of our insulation spots around the Home Energy Hotline House to see how much on average you can save. Savings are based on a 3 bed semi-detached house with gas central heating. If you’re in a home heated differently, you might save even more.

Loft Insulation

How much could you save?
£175 a year by installing 270mm of insulation if you don’t already have any.
£50 a year by topping up existing insulation from 50mm to 270mm.

If your home has no insulation at the moment, 26% of heat is lost through the roof. Loft insulation is an effective way to save energy and money and a well-insulated home keeps warmth exactly where you need it – indoors. Insulating your loft will pay for itself in savings on your energy bills and could still be keeping you warm for the next forty years.

Tanks and pipes

How much could you save?
£40 a year by adding a hot water tank jacket.
£15 a year by adding primary pipe insulation.

Tank and pipe insulation keep your water hotter for longer by reducing the amount of heat that escapes. A new 75mm-thick hot water cylinder jacket will save you around £40 a year. Since you’ll spend less than half that to buy it, you can save the initial cost in less than 6 months. Insulation for hot water pipes will cost around £10 and can save you around £15 a year, which means you should recover the cost of fitting within a year.

Wall insulation

How much could you save?
£135 a year by insulating cavities inside your walls.
£475 a year by insulating the outside of your solid walls.
£445 a year by insulating the inside of your solid walls.

If your home was built from 1920 onwards, the chances are that its external walls are made of two layers with a small gap between them (called a cavity). Filling this gap can reduce the heat lost. If you have a property with solid walls you can insulate them on the inside or the outside.

Insulating cavity walls doesn't have to be expensive, as there is financial help available to many people, and with the savings made on your heating bills it can pay for itself in around two years.

Insulating solid walls is not cheap, but can make a substantial difference to your heating bills.

Solid wall insulation costs from £5,500 to £13,000 depending on what kind you have installed, and can save you around £475 a year.

Draught proofing

How much could you save?
£30 a year by installing draught-proofing measures

Using strips and excluders to draught proof around leaky door and window frames can save around £30 a year on heating bills. It simply fills gaps and decreases the amount of cold air entering your home. There are several types of materials available including brushes, foams, sealants, strips and shaped rubber or plastic.

Draught proofing is an easy and cost-effective way to reduce heating bills for owners and tenants with most materials available from DIY stores. Many of the sealant strips are self-adhesive and fitting brushes to doors or letterboxes is a simple DIY task. If you live in rented accommodation, ask permission from your landlord before doing any work.

Floor insulation

How much could you save?
£60 a year by adding floor insulation

Insulating beneath floorboards will reduce heating bills and improve the comfort of your home. You could save around £60 a year by insulating your floors.

Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. Be careful not to block under-floor airbricks in your outside walls as areas under floors require ventilation to prevent damp and condensation.
