Green Star Energy has launched a loyalty scheme which rewards customers for switching and staying with the firm with gift cards or energy-related products. But it's only open to those on certain tariffs – and if you're thinking of switching, you should always do a full market comparison to find your cheapest deal first.

Customers could be stuck on pricier energy tariffs for up to an extra three weeks as all gas switches are delayed while an IT system is updated.

The energy regulator has put back plans to introduce a 'switching database', which would allow suppliers to contact rival firms' customers on the most expensive standard variable energy tariffs and offer them a cheaper deal.

Theresa May has pledged to set an energy price cap on standard tariffs, in a move designed to cut gas and electricity bills by up to £100/year for those on the worst deals.

British Gas has launched its long-awaited new rewards scheme today and is offering Sky Store movie vouchers to the first 150,000 customers who sign up online, MoneySavingExpert.com can reveal.

Renewable energy supplier Bulb will be reducing its variable dual fuel tariff by about 3% next week, with the firm claiming a recent drop in wholesale costs has led to the £30/year average discount.

Renewable gas and electricity supplier Green Energy is hiking electricity prices by around 9% on average, while gas prices will fall by 5% – meaning dual fuel customers face an increase of about 1.5%.

Energy suppliers won't be able to claw back cash from customers for energy used more than 12 months ago under new proposals by Ofgem to rein in 'back-billing'.

Energy cold-calling is being sparked back into life by smaller providers that increasingly send staff to knock on doors in a bid to persuade customers to switch suppliers. But don't be pressured into switching if an energy salesperson turns up at your home – do a full market comparison in your own time.
