Cheapest gas and electricity tariffs

Updated on 13 September 2017 | 34 Comments

British Gas is hiking energy bills for 3.1 million customers from Friday 15 September. Here are the best gas and electricity deals to switch to.

Energy giant, British Gas, is putting the cost of electricity up on its standard variable tariff by 12.5% from Friday 15 September.

The change will mean a typical household on a dual fuel tariff will pay £76 a year more for their energy, taking the average bill to £1,120.

Anyone sitting on their provider’s standard variable tariff is not only vulnerable to price hikes but is also almost certainly paying far too much for their energy. But there's no need to overpay.

If you want to save money and beat the hike you should switch to a new deal. Here’s where to find the cheapest gas and electricity tariffs on the market.

Other things to consider

Fixing your energy bills is a bit of a gamble, in much the same way as fixing your mortgage or savings.

That’s because prices could come down, which means you end up paying more than you would have done if you were on a variable or even a shorter-term fix.

Having said that, the general trend for gas and electricity prices is to only go one way and that’s upwards, certainly over the long term, although they may fluctuate within a year.

If there’s not much difference between companies, you might want to also consider how good each is when it comes to customer service.

The energy sector isn’t renowned for being brilliant when it comes to dealing with its customers.
