Spending just £3 on an energy-saving home improvement could save you nearly £370 on your energy bills within five years, according to new research.

Energy price rises will impact hundreds of thousands of homeowners from April, after Ofgem confirmed that average energy bills will increase by £693, a rise of 54%. Therefore finding ways to lower your energy bills could be crucial in the months ahead.

Norton Finance has calculated that one of the most cost-effective energy-saving home improvements you can make is draught proofing your home. 

A roll of self-adhesive draught-excluding tape starts at just over £3, Norton Finance says, which can block out unwanted gaps around windows, doors and chimneys that let heat escape. 

And based on savings adjusted to April 2022 energy prices, Norton Finance says DIY draught proofing could save homes around £370 on fuel after five years. 

Don’t Let Heat Escape

Draught proofing is one of the many budget-friendly ways you can prevent heat loss in a house, which happens in a variety of ways in a number of different areas in your home, including through your walls and your roof.

Making small changes to your home’s efficiency, such as using smart light bulbs, can help reduce your bills, but in order to maximise the impact on your energy bills you’ll need to ensure your house is thermally efficient.

Installing new roof insulation can save you around £1,100 on your energy bills after five years, Norton Finance adds. It costs around £285 to insulate a loft in a mid-terrace house, and making the most of available insulation grants can help you manage the cost of installation.

We’ve put together an 8-point plan to lower your bills which can help you navigate the cost of living crisis in the coming months.
