Cavity wall and loft insulation is worth up to £1,100 and can slice up to £480/year off energy bills. Energy firms are offering it for free, as long as you own your home and meet their eligibility criteria – but make sure it's right for your home first.
The Government has announced that up to £5,000 in vouchers will be issued to homeowners in England for energy efficiency improvements, such as installing loft, floor and wall insulation, or double-glazing.
Under the new Green Homes Grant scheme, which launches in September, for most homeowners the vouchers will be worth about two-thirds of the cost of the energy efficient improvements they're making, up to a maximum of £5,000 per household.
You'll be able to apply for the vouchers online from September – we'll update this guide with more info then. Details of the scheme are still limited, but see our Homeowners to receive £5,000 vouchers MSE News story for more on what we know so far.
A new boiler typically costs £2,300, according to the Energy Saving Trust, but some householders can get a grant that can slash this to just an initial £240 outlay, and, in a few cases, even free.
