British Gas is putting up its gas and electricity prices for domestic users.

The cost of gas will rise by 12.4% and the cost of electricity will rise by 9.4%, the company said.

The new prices take effect from 20 September and are expected to add an extra £52 a year to a typical gas bill, which is paid quarterly.

The firm blamed the rising cost of wholesale gas, which has risen sharply since last year, partly as a result of higher crude oil prices.

A typical electricity customer paying quarterly would see their bill rise by an average of £24 a year.
