Top five cheapest energy deals for October: how has the new price cap affected tariffs?

The energy price cap may be at its lowest-ever level, but you can still save on your gas and electricity bills

Top five cheapest energy deals for October: how has the new price cap affected tariffs?

Have you turned your heating on yet? Chillier temperatures and darker evenings prompt a jump in your gas and electricity use at this time of year, all the more so if you’re spending more time at home than usual.

The cut to the energy price cap at the start of October should help keep your bills in check if you’re on a supplier’s standard variable default tariff. But even with the price cap at its lowest level yet, you can still save up to £221 per year by switching to a cheaper deal.

Picking a cheaper energy deal doesn’t mean turning your back on good customer service. We’ve also listed the most cost-friendly tariffs from our Which? Recommended Providers so you can have the best of both worlds.

Can I get cheaper gas and electricity than the price cap?

The energy price cap limits how much a supplier can charge you per unit of electricity and gas. It was cut to its lowest-ever level at the start of October.

This is good news if you’re on a default or out-of-contract tariff (also called standard variable), because your energy company can charge you less than it could previously. Savings are likely to be smaller if you routinely switch supplier to make sure you’re on the cheapest deal.

However, there are now fewer tariffs available that will make for big savings. We’ve found just three tariffs which would save at least £200 per year in comparison with the price cap, based on a home using a medium amount of gas and electricity. The previous time the price cap was changed, there 68 deals that would have saved the same home at least £200 per year.

We’ve highlighted those deals in our table below. Even if none of them take your fancy, our research also found 38 deals which would save our example household at least £100 per year, so it’s still well worth switching when an existing deal comes to its end.

Top five cheapest gas and electricity deals

Here, we’ve listed the five cheapest energy tariffs on sale now, based on the annual cost for a household using a medium amount of electricity and gas.

Exactly how much your bills will cost depends on how much energy your home and family uses. Prices also vary by region.

We’ve also calculated how much you would save compared with the current energy price cap (£1,042 for a medium user until April 2021).

Company Tariff Annual price (medium user) Fixed/variable Exit fee Savings compared with price cap
1 Ebico Ebico 12m Summer Saver – paperless £821 Fixed £30 per fuel £221
2 Simplicity Energy 2020 Cabbage – paperless £823 Fixed £35 per fuel £219
3 Avro Energy Simple and SuperConnect – paperless £832 Fixed None £210
4 Green Maple – paperless £854 Variable n/a £188
5 Utility Point Just Join UP 12 m fixed wk40 – paperless £866 Fixed £36 per fuel £176
Prices are based on widely available dual-fuel tariffs for a medium user (using Ofgem averages of 12,000kWh gas and 2,900kWh electricity), paying by fixed monthly direct debit with paperless bills. Prices are averages across regions, rounded to the nearest whole pound and correct on 13 October 2020. Simplicity Energy’s deal is not available in north Scotland.                  

Four out of five of this month’s cheapest deals are fixed for a year, so your prices will be set for the length of the deal. Three of them have exit fees, though, so you would have to pay at least £60 if you wanted to move to another deal before the end of your contract.

Variable deals, including the one listed from Green, don’t have exit fees. But the price you pay can change if the energy firm decides to raise or lower its prices. If it does this, you will get 30 days’ notice.

Three of this month’s cheapest deals come from firms included in our energy companies’ customer satisfaction survey – find out how Avro Energy, Ebico and Utility Point fared.
