Priced at £804.88 for someone on typical usage (as calculated using average consumption figures from Ofgem, the energy regulator), our Energy Bill Buster is streets ahead of the standard energy tariffs that most people are on. These are priced at around £1,100 a year for average energy users.
The average price of the standard tariffs from the six biggest energy firms is £1,094 a year for someone paying by monthly direct debit - so switching to the Energy Bill Buster would save a typical user almost £290 over the course of 12 months.
The average big energy firm standard tariff price for someone paying quarterly by cheque or cash is £1,173, so the savings here are even more substantial, at almost £370 for the year.
But you'll need to act quickly. This exclusive deal is only available until Wednesday 2 December.
The great news for millions of British Gas customers is that they can switch to this new tariff – and potentially chop hundreds off their annual costs – without paying any exit penalties on their current deal.
The same applies to customers of Sainsbury's Energy, which is powered by British Gas.
Cheapest since 2011
The MoneySuperMarket Energy Bill Buster is British Gas’ cheapest tariff since its Web Saver 11 deal, which was available until May 2011 (again calculated using data from Ofgem).
Our new exclusive offer is a 12-month fixed-rate dual fuel tariff, which means it includes both gas and electricity supply. And because it’s fixed, you know the rate you pay for each unit of energy you use won’t increase for the duration of the contract.
