These are all of the fixed energy tariffs set to end - will you see a price hike?

Millions of customers are at risk of seeing a hike in their energy bills at the height of winter, as fixed tariffs are set to end before the end of the year.

A total of 94 fixed term tariffs will end between now and 31 December 2019, according to new data from MoneySuperMarket.

Winter price hikes?

Ofgem's new price cap level recently came into force, setting the maximum price suppliers can charge for each unit of energy.

The cap is now set at £1,179 for the average customer on a standard or default tariff - hundreds of pounds more than the best deals on the market.

A total of 32 fixed tariffs are due to expire at the end of October, followed by 28 in November and a further 34 in December, impacting millions who may automatically roll onto a default standard variable tariff.

Big Six suppliers British Gas and EDF Energy are among those with tariffs ending by the end of December, alongside emerging suppliers including Co-operative Energy, Shell Energy and PFP Energy.

Avoiding penalty fees

Standard variable tariffs tend to be the most expensive as prices can fluctuate in line with the market, whereas fixed rate tariffs are set for a period of time.

Many of the deals set to end by 31 December include exit fees, but customers are often unaware that they are allowed to switch suppliers within six weeks of the tariff end date without being charged a penalty.

Stephen Murray, energy expert at MoneySuperMarket, said, "Make sure you don't fall into the trap of being placed onto an expensive standard variable or default tariff.

"If you're on a fixed rate tariff that's coming to an end, you should act now to lock in another fixed rate deal, so you can avoid being stung by price rises over the colder months.
