Is your energy bill about to rise?

Fixed-rate energy deals ending on 30th September


Bill increases could be on the horizon when some fixed-price energy deals end this month

Household could see energy bills increase as 23 fixed-price tariffs expire at the end of this month and default to standard-rate tariffs. 

Some fixed-rate deals from British Gas, Co-operative Energy, Extra Energy, First Utility, M&S Energy and Scottish Power will end on 30 September. 

Customers’ bills will rise in most cases, as standard tariffs are nearly always more expensive.

Standard energy tariffs cost more

In most cases, standard tariffs are more expensive than fixed-term deals. 

The exceptions are British Gas’s Fix and Reward September 2015 and Scottish Power’s Platinum Fixed Energy October 2015 – where an average customer’s bill will  fall when their deal ends. 

If your tariff is on this list don’t wait to switch to a better deal. You can change suppliers or tariffs now without paying an exit fee, even if your contract says there is one. This is because exit fees no longer apply once you’ve been notified that a fixed-rate tariff is coming to an end.  

Cheapest energy deal

The cheapest dual fuel tariff currently available is Premium Energy Saver from GB Energy Supply which costs £831 a year.*
