As the nights are drawing in, TV money guru Martin Lewis has revealed how to save a whopping £290 on energy bills.
Temperatures are dropping quickly across Britain as we prepare for a frosty winter.
Many Brits will be turning their heating on to stay toasty over the festive period - especially as millions are forced to stay at home during lockdown.
The Money Saving Expert revealed in his weekly newsletter that the MSE Big Energy Switch is back for a 16th year in a row.
Mr Lewis revealed that users could bag cheaper deals on energy tariffs and get a fix rate guarantee, which will lock the rate with no price hikes until January 2022.
He said: "Winter's coming and we're all set to be at home a lot more. That means higher energy bills.
"To help, we're launching our 16th MSE Big Energy Switch, where we lever our huge user base."
The finance juggernaut has bagged three fixes but unfortunately, they're not available on prepayment methods or in Northern Ireland.
The fixes guarantee your rate will be locked in, with no price hikes - not even during the colder winter months.
MSE explains Shell, at £842 per year on typical usage, is the market's cheapest deal and British Gas, at £857 per year for new customers only, is the cheapest "Big 6" deal.
On average, customers who make the switch will save a small fortune of £290 over that time, The Liverpool Echo reports.
Alternatively, if you want price certainty for longer, there's also the Green Network Energy two year fix at £913 a year, which is the cheapest two winter fix.
If you want help making the switch, you can access the deals via MSE's new whole-of-market tools.
It comes as swathes of the UK brace themselves for foggy and frosty weather this week.
Many parts of the UK will be seeing sunny spells ahead of a drop in temperature and wet weather moving in this week.
Bookies have already slashed odds on this winter to be the coldest on record in the UK.
Coral’s John Hill said: "It looks like we could be set for a long and bitter winter ahead and that is reflected in our betting as we are odds-on for it to be the coldest on record.
"The one upside for many on dropping temperatures is that the prospects of a White Christmas this year are improving with every day.”
