Top five cheapest energy deals for August 2019

Best gas and electricity tariffs for high users, low users and holiday homes

When it's hot, don't be fooled into thinking that your energy bill is on ice. If you have an air conditioner or hot tub, your meter will be guzzling power.

But the bigger your bill, the more money you could potentially save. High energy users could cut around £562 from their bill over the next year, while low users could spend around £294 less - both compared with the current price cap on standard tariffs.

Plus if you have a holiday home, where you only spend a few weeks a year, you could be better off with a gas and electricity deal without a daily standing charge.

Our August analysis of more than 300 gas and electricity deals reveals the cheapest overall energy tariffs for households using different amounts of gas and electricity.

Cheapest gas and electricity deals

We've listed the five cheapest gas and electricity deals for this month, based on the price for a year for a household using a medium amount of energy.

You'll see the annual average price and how much you could save compared with the current price cap. At the moment this is set at £1,254 on average per year for homes using a medium amount of energy on standard or default tariffs. Many of the biggest firms are charging this amount, but it's predicted that it will be cut by around £70 from autumn.

Even so, in comparison to the price cap, you could still save over £300 by choosing the cheapest deal.

Your exact spend depends on how much gas and electricity you use.

Top five energy deals for medium users

  1. £846 - Outfox the Market, One Variable Tariff 6.0 - paperless. Variable tariff with no exit fees. £408 saving compared with the price cap.
  2. £865 - Outfox the Market, One Variable 1.0 Plus - paperless. Variable tariff with no exit fees. £389 saving compared with the price cap.
  3. £867 - Green, Oak - paperless.  Variable tariff with no exit fees. £387 saving compared with the price cap.
  4. £873 - Orbit Energy, Beat the Cap Extra, Jul19 - paperless. Variable tariff with no exit fees. £381 saving compared with the price cap.
  5. £881 - Outfox the Market, Fix'd 19 2.0 - paperless. Fixed tariff for 12 months with no exit fees. £373 saving compared with the price cap.

Three of the five cheapest deals are from Outfox the Market. Two are variable deals and so have no exit fees if you want to switch again. But the price can change if the company decides to raise or lower its prices. The fixed deal has no exit fees attached to it either.

Energy supplier Green is one of the newest on the market, while Orbit Energy is also a relative newcomer. In fact all three suppliers were too new to get a customer rating in our latest energy satisfaction survey. So we can't vouch for how good their service is.

Cheapest deals for high energy users

If you're lucky enough to have a hot tub in the garden, resort to air conditioning when temperatures spiral upwards, or have a large home or family, you're likely to use more gas and electricity than average.

The deals listed are the cheapest on sale now for high energy users. They could help you cut around £562 from your annual energy bill, in comparison with the current level of the price cap.

Top five deals for high energy users

  1. £1,177 - Outfox the Market, 1.0 Plus - paperless. Variable tariff with no exit fees. £562 saving compared with the price cap.
  2. £1,187 - Orbit Energy, Beat the Cap Extra, Jul19 - paperless. Variable tariff with no exit fees. £552 saving compared with the price cap.
  3. £1,189 - Outfox the Market, One Variable Tariff 6.0 - paperless. Variable tariff with no exit fees.  £550 saving compared with the price cap.
  4. £1,217 - Green, Oak - paperless. Variable tariff with no exit fees. £522 saving compared with the price cap.
  5. £1,230 - Outfox the Market, Fix'd 19 2.0 - paperless. Fixed tariff for 12 months with no exit fees. £509 saving compared with the price cap.

The cheapest five deals are the same as those for medium users, though not in the same order. None have exit fees, so you can leave before the end of the deal, penalty-free. Four of the deals are variable, which means the price could go up or down if the company changes its prices.

If you'd rather know that your prices will be steady, consider a fixed deal.

Cheapest deals for low energy users

Smaller homes, including flats, and households of fewer people are more likely to be low energy users. You might also fit into this bracket if you and your home are particularly energy efficient.

If so, there are potential savings of £294 per year if you choose the cheapest deal compared with a deal at the level of the price cap.

  1. £572 - Outfox the Market, One Variable Tariff 6.0 - paperless. Variable tariff with no exit fees. £294 saving compared with the price cap.
  2. £588 - Green, Oak - paperless.  Variable tariff with no exit fees. £278 saving compared with the price cap.
  3. £602 - Outfox the Market, Fix'd 19 2.0 - paperless.  Fixed tariff for 12 months with no exit fees. £264 saving compared with the price cap.
  4. £612 - Avro Energy, Simple and Supersave - paperless. Fixed tariff for 12 months with no exit fees. £254 saving compared with the price cap.
  5. £616 - Nabuh Energy, Zara Tariff - paperless. Fixed tariff for 12 months with no exit fees. £250 saving compared with the price cap.

Three of the top five cheapest deals are the same as for medium users. However, the tariffs from Avro Energy and Nabuh Energy work out relatively cheaper for low users, compared with those who use more gas and electricity.

None of the tariffs have exit fees so you're free to switch during the tariff if you find a better deal.

Only Avro Energy was big enough to be included in our most recent energy companies satisfaction survey. Find out what customers think of Avro Energy.

Energy deals for second homes and holiday homes

Most energy deals are made up of two elements:

  • Standing charge: a daily sum for being connected to the gas or electricity network
  • Unit rate: the amount payable per unit of gas or electricity you use

You'll pay the standing charge regardless of whether you use any energy. So if you have a second home or holiday home where you don't live for much of the year, it might help cut your bills to choose a tariff with no standing charge. This means you only pay when you use gas and electricity.

Few companies offer these but we've rounded up those currently on sale to help you decide whether this is the right option for you.

Energy tariffs with no standing charge

Energy firm and tariff nameElectricity unit rateGas unit rate
Ebico Zero Green Fixed v3£0.25
£0.07
Utilita Premium Energy£0.47 for the first 91.25 units, then £0.20
£0.35 for the first 91.25 units, then £0.04
Utilita Smart Energy£0.30 for the first 182.5 units, then £0.19£0.17 for the first 182,5 units, then £0.04

Data from Energylinx. Unit prices are averages across the regions in which the tariff is available and based on paying by monthly fixed direct debit. They are rounded to the nearest whole penny. Three month prices are based on a quarter of low user usage (475kWh electricity and 2,000kWh gas).

Tariffs with no standing charge often have higher unit rates, in comparison with those deals which do not have a standing charge. So if you use a larger amount of power and gas, you may well be better off with a deal with both standing charge and unit rate.

For example, Ebico's tariff above charges 25p per unit of electricity. If you live in the property for around three months of the year, it will cost you around £250 (based on a quarter of a low user's annual usage). But if you spend the whole year there, it would cost you £1,006 (again, based on a low user's annual amount) - so you'd be better off with a different deal.

So, before you switch, compare gas and electricity prices based on the amount of energy you use in the property each year. You can find this on your annual statement, latest bill or in your online account.

Winter is coming: a warning

There's a price cap currently limiting the amounts companies can charge customers who are on standard or default (or prepayment meter) deals. The level of the cap is expected to be cut next week, and come into force from 1 October.

But if you're on a price-capped tariff, it doesn't mean you're getting good value for money, as we've shown above.

Plus, if you're on a fixed deal, the price cap doesn't apply to you. This means that companies can still sell fixed deals which cost more than their price-capped tariffs.

Typically, prices increase in winter as the cost of wholesale energy is higher. So don't wait until then to look for a cheaper fixed deal.

Which? energy pricing research

Prices are based on a dual fuel tariff available in all regions in England, Scotland and Wales paying by monthly direct debit, with paperless bills.

Energy use is based on Ofgem's annual average figures for annual usage:

  • Low users: 8,000kWh gas and 1,900kWh electricity
  • Medium users: 12,000kWh gas and 3,100kWh electricity
  • High users: 17,000kWh gas and 4,600kWh electricity

Data is from Energylinx. Price given are averages across regions, rounded to the nearest whole pound and correct on 1 August 2019.
