Top five cheapest energy deals for July 2018

Plus find out why which region you live in affects how much you pay for energy

Keep your cool in the heat by making savings on your energy bill. Switch away from Npower’s pricey standard tariff and you could save £433 in a year.

Exactly how much you’ll save depends on your current energy deal and where in the country you live.

Npower’s standard tariff is the most expensive Big Six variable tariff in most – but not all – areas. Those living in some areas can save £53 more a year on energy than others.

Read on to find out the priciest tariff to avoid where you live, and if you live in the region that could save the most.

What you need to know about this month’s cheapest gas and electricity deals

Although the temperatures have risen over the past month, the savings you can make on gas and electricity have remained stable.

In June’s cheapest deals we found the biggest saving you could make was £434 – and it’s almost identical (£433) this month.

But don’t assume that savings are here to stay. Last month, four of our five cheapest deals could save you more than £400. It’s only two this month.

So now is a good time to starting switching. Not sure how? Check our simple steps to switching energy suppliers.

July’s cheapest energy deals

Below, we’ve listed the five cheapest gas and electricity energy tariffs for medium users, to give you an idea of what you should be spending. You should compare prices using your own usage information to get the most accurate quote.

The prices are annual. We’ve also noted the tariff and how much each tariff will save a medium user compared with EDF Energy and Npower’s standard tariffs (respectively the cheapest and most expensive of the Big Six firms, taking into account announced price rises).

If you’re an Eon customer, be aware that it’s increasing its prices by 4.8% (£55 on average) on 16 August. Also, back in March, the supplier scrapped two discounts and increased its standing charge for some customers.

Do you live in a more expensive energy region?

Gas and electricity are supplied in 14 different regions of Great Britain (Northern Ireland is separate – find out more about Northern Ireland gas and electricity suppliers). Deals can be priced differently depending on where you live.

This means that the cheapest deal in the South West costs £65 more a year than in the East Midlands. This deal has the same name, and is from the same company (Utility Point’s Flexi Online Tracker 18 Wk24).

The biggest saving between a Big Six standard tariff and the cheapest deal is available to those living in the Midlands. Customers here could potentially save £469 a year. If you live in the South West, you’d save £416 – a difference of £53.

While Npower’s standard tariff is the priciest of the Big Six companies’ variable deals on average across the country, there are two regions in which another company’s standard tariff is more expensive:

Why do gas and electricity prices vary by region?

The prices customers pay in different regions are influenced by:

  • how much energy suppliers sell to customers in the area
  • how much energy suppliers buy from the national grid in that area
  • how much energy distributors for the region charge suppliers.

Plus energy suppliers all have their own strategies for setting prices.

Do you trust energy companies?

Our research has discovered that only car dealers are distrusted more than energy firms. A third of people (34%) say they don’t trust energy companies, compared with 54% who distrust car dealers.

It could be that the past few months of energy price rises has impacted how people feel about energy firms.

Even train companies are distrusted by slightly fewer people (32%), despite months of disruption on certain routes.
