Press release:

3 million British Gas customers face 12.5% electricity bill hike

  • The UK’s biggest energy supplier, British Gas, is to hike electricity prices by 12.5% or £76 from 15 September[1], blaming rising policy and network costs
  • A typical dual fuel customer will see their bills rise from £1044 to £1120 a year – the equivalent of £235m across the country[1]
  • The rise follows an extended price freeze[1]
  • Customers can save up to £618[2] by switching to a competitive fixed deal.

Following an extended price freeze, British Gas has today announced that it is hiking the cost of its standard variable tariff for electricity by 12.5% or £76 a year[1] for 3.1 million customers[1].

The increase, which takes effect from 15 September[1] will add an annual total of £235.6 million to its customers’ energy bills[3]. While it remains the cheapest big six standard tariff it is still £286 more expensive than the cheapest deal available today[4]. British Gas has also announced that it will give a one-off credit £76 to the accounts of more than 200,000 vulnerable customers who receive the Warm Home Discount[1].

Commenting on the news, Claire Osborne, energy expert at, says: “With these hikes set to kick in just before the winter, this is a body blow for consumers. At a time when living costs are rising faster than wages[5], this hike could push many families into the red. Customers should not be lulled into a false sense of security. The British Gas standard tariff remains the cheapest among the big six but it is still £286 more expensive that the cheapest deal on the market today.

“It’s time to switch supplier and send a message that price rises like these just aren’t acceptable. Seven in ten households[6] are overpaying for their energy on expensive standard tariffs, yet within ten minutes they could switch and save hundreds of pounds – as well as protect themselves against further hikes by fixing their tariff.”
