  • 167 fixed rate tariffs are ending in February 2021, which could affect more than 300,000 customers
  • Average increase in energy bills could hit £66 a year per household
  • Total cost to households around the country could be nearly £20 million if people do not switch and are rolled onto their supplier’s default tariff for the year

15 February 2021 – More than 300,000 households could be automatically switched onto more expensive ‘default’ energy tariffs in February if they do not switch tariff or provider when their deal comes to an end.

In February, there are 167 fixed energy tariffs coming to an end, according to new research by comparethemarket.com. The average annual cost of a fixed rate energy tariff ending in February is £918. Rolling off fixed term deals onto default tariffs could collectively cost UK households over £20 million a year compared to their current energy costs.

Analysis of the fixed tariffs ending in February finds that the average increase to energy bills could be £66 per household. comparethemarket.com’s data and analysis reveal that if customers do not switch when their fixed tariff ends, energy companies are set to benefit from a huge ‘inertia windfall’.

Households that do not switch before April face an additional increase to their bills. Ofgem, the regulator, recently announced the default energy price cap will change from its current level of £1,042, to £1,138, for dual fuel typical consumption households. The increase of £96 includes an additional £23.69 that the regulator has allowed suppliers to recuperate from unpaid bills from households that have experienced financial difficulty during the pandemic.

Peter Earl, Head of Energy at comparethemarket.com, said:

“Time and time again we see people fall into the inertia trap. If you do not switch your supplier at the end of your fixed term it is almost certain that you will end up paying more for your energy than you should be.

“With most people back at home due to coronavirus restrictions, energy consumption is likely to be much higher than usual, with bills increasing as a result. Those in a position to switch should consider doing so, as it will help reduce the overall amount you pay for energy and ensure you are getting better value for money. There is no better way to cut down on the cost of energy than by switching provider.”

All data has been secured through comparethemarket.com and data supplied by a third party Energyhelpline. The total number of households is calculated using comparethemarket.com customer numbers and extrapolated using its estimated market share. The cost to consumers is then a multiplication of the number of customers affected and the difference between the fixed tariff and the default tariff of that provider annualised. Please note, this analysis excludes a number of tariffs for which comparethemarket.com cannot currently determine a clear end date.
