Npower has joined rival British Gas in announcing it is increasing gas and electricity prices in the UK.

Npower will increase the price of gas by an average of 8.8% and electricity by 9.1% from 26 November.

Earlier, British Gas, the UK's biggest energy supplier, raised its charges for both types of fuel by an average of 6%, adding £80 a year to the average dual fuel bill.

The firms both blamed the government's policies as well as wholesale prices.
