Support is available to help you pay your energy bills, plus energy grants and offers can help cover the initial cost of installing energy efficient features in your home. Find out about the different schemes and whether you qualify.

The average household could be wasting hundreds of pounds each year because their property isn't energy efficient. You may also be spending more money than you need to if you’re eligible for help with paying your gas and electricity bills.

Making your home more efficient will make it cheaper to run over time, and the changes can help make it more cosy too.

Cut your energy bills by following our tips on saving energy at home.

Help paying your gas and electricity bills

Even if none of those apply to you, other help may be available from your supplier. Find out more about what help is available if you're struggling to pay your energy bills.

Free insulation and energy efficiency grants from energy suppliers 

The Energy Company Obligation (ECO) provides grants for energy efficiency measures such as cavity wall insulation and loft insulation

You might also be able to get help with replacing an old, inefficient boiler or other heating system.

The ECO grants are provided by energy suppliers, rather than the government. The biggest companies are obliged to help households make energy-saving improvements.

They're mainly aimed at low-income households and those in vulnerable situations. However, the eligibility criteria for ECO are quite complex. 

To find out if you could qualify, check the Simple Energy Advice website or call Home Energy Scotland on 0808 808 2282. Find out more in our ECO guide

How much money could energy efficiency measures save?

There are many ways to save energy and money in your home. Some, such as draught proofing and fitting energy-saving light bulbs, are cheap and easy to do. 

Loft insulation and cavity wall insulation are relatively straightforward to install and will yield bigger savings. Solid wall insulation is more expensive, but the long-term savings can be even greater. 

Here are the estimated savings per year for different types of insulation:


Semi-detached house
Detached house
Mid-terrace house
Bungalow
Mid-floor flat
Cavity wall insulation
£155
£255
£95
£105
£75
Loft insulation (0-270mm)
£135
£315
£125
£195

Floor insulation

Solid wall insulation
£210
£350
£130
£140
£105

Figures are estimates from the Energy Saving Trust for England, Scotland and Wales and based on a gas heated home. Last updated September 2021. 

Compare these annual savings with how much they cost to install to find out how long it will take for the insulation to pay for itself.

If your home is already well insulated, fitting a modern condensing boiler is pricey but replacing an old boiler with a modern one with heating controls could save you more than £200 a year (in a three-bedroom house).

Other ways to save money on energy

As well as getting help to install energy efficiency measures to help cut your energy use, it's worth checking that you’re on the best-value energy tariff. 

Even with high gas prices, it's worth using our free service Which? Switch to compare energy prices and check that your current deal is still good value. For better price certainty, choose a fixed deal. 

Out-of-contract and standard default gas and electricity tariffs are limited by the price cap. But they can still change price twice per year when Ofgem updates the price cap. So there's no guarantee your bills won't rise.

Earn cash for generating renewable energy

Installing energy-generating technologies, such as solar panels, is something you should only consider after you've made your home as energy efficient as possible. 

The upfront costs of installing generation at home can be high. But the Renewable Heat Incentive (RHI) helps to offset the initial expense of installing renewable heating. The Smart Export Guarantee can pay for electricity you generate at home and export.

These schemes support renewable technologies including solar panels,  ground-source heat pumps and air-source heat pumps.
