ScottishPower has become the last of the big six energy suppliers to cut its tariffs.

The company has cut its gas prices by an average of 5%, effective from 27 February.

Earlier in the day, E.On announced it was to cut its standard electricity prices by 6%.

But ScottishPower warned that rising demand for energy would "inevitably lead to to higher energy costs in the long-term".

It said that the 5% cut would equate to an average annual price cut of £36 for both dual fuel and gas-only customers paying monthly by direct debit.

ScottishPower's cut means that four of the six big energy suppliers have cut gas prices and the other two have cut electricity prices in recent days.

They attributed the cuts to recent falls in wholesale prices for energy.
