Could you save £313 on your energy bill?

The cheapest dual-fuel energy deal available UK-wide is £873 per year for a medium user on average. If you’re on the priciest standard deal with one of the biggest six energy firms (Npower), switching could save you up to £313 in a year.

If you’re with the UK’s biggest energy firm, British Gas, it currently has the cheapest standard tariff of the Big Six. However, you could still save up to £171 on average over a year by switching to the cheapest deal.

British Gas doesn’t offer a cheaper deal than its standard tariff at present, but it’s the exception – most energy firms’ standard tariffs are among their priciest deals.

Is UK energy expensive?

Energy regulator Ofgem recently published a comparison between electricity and gas prices in the UK and 14 other countries in Europe. It found that the UK was the second-cheapest for gas and sixth-cheapest for electricity, on average, for a medium user from July to December last year.

Bulgaria had the cheapest gas and electricity, while gas was priciest in Sweden, and electricity was priciest in Denmark.

(How our prices are calculated: Prices are based on a dual-fuel tariff for an average user (using 3,100kWh of electricity and 12,500kWh of gas per year), paying by monthly direct debit, with paperless bills and are averaged across all regions. Exact prices can vary according to region, usage and payment method. Prices are rounded to the nearest whole pound. The prices given in the table above are correct as of 1 June 2017.)
