Top five cheapest energy deals for October 2017

Small gas and electric suppliers could save you the most money

One of the country’s biggest energy firms has the third priciest deal this month – £1,166 a year. We’ve also uncovered 27 dual-fuel energy tariffs costing less than £900 a year for the average user. All but two are from smaller energy suppliers. 

The two exceptions are EDF Energy and First Utility, which are both currently selling tariffs costing £872 per year.

The priciest deals from big energy firms are from Npower (£1,166) and Economy Energy (£1,205). If you stay put on Economy Energy’s variable tariff, you’ll pay £385 more than you need to in a year.

Have you cut your energy use?

Energy regulator Ofgem has reduced the average energy consumption figures it uses to calculate average energy spend – and which we use to calculate energy savings.

Ofgem did this because we are all using less electricity and gas than previously, thanks mainly to more energy-efficient appliances.

This means that our savings figures might look smaller than in previous months. That’s because they’re now (from 1 October 2017) based on lower gas usage, which more accurately reflects the average amount we’re all using.

£2 coin on top of a gas ringBut if you haven’t changed energy deal over the past year (and you’re on a standard deal), then price rises will have pushed your bill up. So it’s worth shopping around for a cheaper gas and electricity deal, even if you’re careful to save energy at home.

Prices are based on a dual-fuel tariff for an average user (using 3,100kWh of electricity and 12,000kWh of gas per year), paying by monthly direct debit, with paperless bills, and are averaged across all regions.

Exact prices can vary according to region, usage and payment method. Prices are rounded to the nearest whole pound. The prices given above are correct as of 1 October 2017.)
