British Gas, Npower and now Powergen have already announced lower tariffs in response to falling wholesale gas prices.  As wholesale gas prices have fallen by about 50% over the past six months.  Three of the Big Six have now announced price reductions and the others must follow.  Scottish & Southern Energy, with about seven million customers, has also said it will cut its tariffs soon to keep its prices lower than those of British Gas. We widely expect with this recent announcement that Scottish & Southern Energy the UK’s third largest energy supplier and the UK’s number one renewable supplier, will announce its reductions within days.  But this is likely to prompt swift retaliation from British Gas who are keen to remain the cheapest UK energy supplier in order to regain the one million customers lost last year.
