Switch supplier to save money on energy without turning down your thermostat

It doesn’t pay to be a loyal energy customer, as some big energy suppliers are starting to offer cheap energy deals to new customers only. So it’s time to switch energy supplier to secure a cheaper price for gas and electricity in time for winter.

If your supplier tells you the cheapest deal for you, it may not be the cheapest deal it offers overall. This is because, as an existing customer, you’re not eligible for a new-customer deal. 

One of this month’s cheapest deals, from Eon, is a new-customer deal. So this makes it all the more important to keep an eye on how much you pay for gas and electricity, and check whether you could save money by switching to a different supplier or tariff.

This month, our research has found that you could save up to £333 by switching from one of the big six suppliers’ standard variable deals, usually among the priciest, to one of the cheapest UK-wide deals. And newly launched deals are £25 cheaper than last month.

How these prices are calculated: Prices are based on a dual-fuel tariff for an average user (using 3,100kWh of electricity and 12,500kWh of gas per year), paying by direct debit and are averaged across all regions. Exact prices can vary according to region, usage and payment method. The prices given in the table above are correct as of 12 October 2016.


If you live in north-east England, Future Energy’s Future Connect – Paper and Paperless dual fuel tariff will save you £13 more than the cheapest UK-wide deal. It’s a one-year fixed deal, and you’ll be charged £30 per fuel if you leave early.

Robin Hood Energy's Nottingham v5 – Paperless tariff could be slightly (£2) cheaper than the lowest UK-wide deal; but only if you live in the East Midlands where it’s offered. It’s also a fixed tariff but there are no exit fees if you want to switch before it finishes.
