While acknowledging that the price rises would be unwelcome news for customers, the supplier is facing rising wholesale prices, as well as higher costs to upgrade the national grid, and is also obliged to deliver the government's policies for a clean, energy-efficient Britain.

British Gas Residential profits in the second half of 2012 are expected to be around 15% lower than for the same period of 2011, British Gas said. Centrica's adjusted earnings last year totalled £1.33bn.
"We simply cannot ignore the rising costs that are largely outside our control, but which make up most of the bill," said British Gas Managing Director, Phil Bentley. Around 85% of costs behind the average dual fuel bill are largely beyond the control of British Gas, the firm claimed.
"Britain's North Sea gas supplies are running out, and British Gas has to pay the going rate for gas in a competitive global marketplace. Furthermore, the investment needed to maintain and upgrade the national grid to deliver energy to our customers' homes, and the costs of the Government's policies for a clean, energy efficient Britain are all going up," he continued.
Bentley claimed "rising prices don't have to mean rising bills" as he highlighted a number of energy saving initiatives the group is offering free to customers.
