Poor energy efficiency could be adding £300 a year to your energy bills

The average household could be losing hundreds of pounds a year because of poor energy efficiency. With gas and electricity prices likely to rise in the long term, you could lose a lot more money in the future.

Energy grants and offers can help cover the initial cost of installing energy-efficient features. 

Keep reading to find out more about the different schemes and whether you qualify.

Energy efficiency grants, discounts and freebies

The Energy Company Obligation (ECO) gives out grants for energy-efficiency measures, such as wall insulation. The eligibility criteria for ECO, however, are quite complex. 

To find out if you could qualify, call the Energy Saving Advice Service on 0300 123 1234 and find out more in our guide to ECO.

Free insulation and other grants from energy suppliers

Energy suppliers have grants that help you pay for energy efficiency measures, including insulation and a free boiler if yours is broken. 

Energy efficiency measures

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 - our guide to cutting your energy costs has more advice. 

Loft insulation and cavity wall insulation are relatively straightforward to install and will yield bigger savings: 

  • Adding 270mm of loft insulation to a typical home with no loft insulation could cut heating bills by up to £140 a year. 
  • Cavity wall insulation will save you up to £160 a year.

Larger projects, such as fitting a modern condensing boiler or solid wall insulation, are more expensive. But the long-term savings can be even greater: 

  • A new boiler with modern heating controls could save you £340 a year 
  • Solid wall insulation gives you savings of up to £260 a year

(All for a three-bedroom semi-detached house.)

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 can be high. But the Feed-in Tariff (FIT) and the Renewable Heat Incentive (RHI), also known as clean-energy cashback schemes, help offset the initial expense of installing renewable energy technologies, such as solar panels, wind turbines and ground-source heat pumps

On top of money saved by not having to use traditional sources of energy, such as grid electricity or mains or tanked gas, generating electricity with solar PV also means you can sell energy back to your supplier for a guaranteed price. 

See our dedicated guides to find out more about FIT and RHI.
