Big six energy supplier SSE has announced an average price increase of 8.2 per cent for its gas and electricity prices.
It's expected to impact around 4.4 million customers on its electricity tariffs, and 2.9 million on its gas tariffs from 15 November. The price rise won't affect those signed up for its fixed tariffs, however.
SSE's average standard dual-fuel bill will rise to around £1,380 per year. The energy supplier has pledged, as a result of the increase, to not increase prices before next autumn (2014).
Will Morris, managing director of SSE's retail business said of the decision: "We're sorry we have to do this.
"We've done as much as we could to keep prices down, but the reality is that buying wholesale energy in global market, delivering it to customers' homes, and government-imposed levies collected through bills - endorsed by all the major parties - all cost more than they did last year," he added.
It's been forecast in that customers based in the south-east will be worst affected by the price increase - with prices rising by 9.7 per cent.
Mr Morris has stated that he expects the company to receive criticism from the government for the decision.
However, he went on to say: "But over many years, policymakers themselves have failed to highlight adequately the cost to consumers of the policies they have pursued in government.
"They can't expect to have power stations replaced with new technologies, the network to be upgraded and nationwide energy efficiency schemes all to be funded for free.
"And as an energy provider, we are in the unenviable position of having to pass this cost onto consumers through energy bills," he concluded.
Some of the United Kingdom's big six energy suppliers are partaking in the government's Green Deal. The Green Deal is an initiative that allows consumers to apply to receive financial support to install energy efficiency measures in the home - such as a gas boiler. Like a loan, the funds can be paid back in installments through energy bills.
