British Gas summer scheme offers half-price electricity on Sundays

Use applies between 11am and 4pm and runs to 24 September for customers joining PeakSave plan

British Gas is offering its customers half-price electricity every Sunday this summer to shave millions of pounds from energy bills - but only for those willing to carefully schedule their cooking, housework and video gaming.

The UK's biggest energy supplier said it would charge electricity use between 11am and 4pm on a Sunday at half the usual rate from this Sunday to 24 September for all customers who sign up to its PeakSave scheme.
