Scottish Power

Energy firm SSE is to be investigated by Ofgem over concerns it restricted competition in the electricity connections market.

Scottish Power is the latest energy provider to announce price cuts this year, but the drop doesn't take effect until 20 February and the 4.8% reduction only applies to gas.

Customers of electricity provider iSupplyEnergy will no longer be blocked from switching if they don't tell it they're moving elsewhere, following concerns flagged by both customers and MoneySavingExpert.com.

SSE, Scottish Power and energy generator GDF SUEZ/IPM are to pay penalties totalling £4.6 million to charity following their failure to deliver energy efficiency measures on time.

First Utility is the latest energy company to face a backlash from disgruntled customers over unresolved complaints and long call waiting times. But it's admitted it's at fault and says it's investing £20 million to improve its customer services.

Scottish Power is facing a ban on sales activity unless it must meet tough targets Ofgem has set to fix the firm's customer services problems, it's been announced today.

SSE has cut switching times to 17 days from today, while First Utility has confirmed it will introduce faster energy switching from 10 November ahead of the New Year's Eve deadline given by Ofgem.
