But don’t worry, you don’t have to just yet.
The specialists at Which? have revealed a foolproof method to ensure your house remains warm throughout the chillier periods following the recent price surge.
From October 1st, the energy price cap will see a rise of over two per cent to £1,755, adding an extra £35 onto annual gas and electricity bills for those on the standard tariff.
A quarter of the average UK energy bill last year was profit for the big energy companies.
Meanwhile, almost three million households in England suffer fuel poverty.

Ofgem adjusts the cap, which is primarily based on the cost of energy on wholesale markets. However, this two per cent increase is partly due to the higher cost of transporting energy and the additional support measures that have been implemented for consumers.
Therefore, to assist you in warming your property for less this autumn and winter, the specialists at Which? have revealed a straightforward and budget-friendly trick utilising a common household item.
In an Instagram post, they said: “Energy companies hate this hack!”
Elaborating further, Which? explained that all you’ll require is a roll of radiator reflector – or tin foil, as an affordable alternative.

They said: “Maximise your heat! Putting foil behind radiators allows the heat to be reflected back into the room. This is particularly effective on external walls. You can pick up radiator reflector foil for around £8. It’s padded and usually has an adhesive backing so it’s really easy to install.
“But kitchen foil also works as a low-cost alternative. So measure the distance between the brackets on your radiators and cut the foil to size.”
Which? captioned the post: “Putting tin foil behind your radiators is a great way to heat your home for less! It’s quick, cheap and easy – a perfect hack for everyone, even if you’re not a confident DIY-er.”
