HUNDREDS of Huddersfield families are being hit as energy firms Npower and Scottish Power confirmed steep hikes in gas and electricity prices.

Npower said prices for gas customers would increase by an average 26%, with prices for electricity customers up by 14%, both with immediate effect.

Scottish Power followed a few hours later by announcing it would increase gas prices by an average 34% and electricity prices by 9% from Monday.

The firms have 11.8m customers between them.

Both blamed the soaring wholesale costs, saying they had made current pricing levels unsustainable.

They are the last of the country’s suppliers to hit households with increases in recent weeks, following moves by British Gas, EDF, E.On and Scottish & Southern Energy.

Npower said the average gas customer would see an average annual increase of £162 with electricity bills rising by an average £60.
