Pay As You Go Energy Suppliers: Who is the Best in the UK?


As a nation, we’re spending way too much on our energy bills. As in, hundreds of millions too much! In a 2020 report by the National Audit Office (NAO), which you can read here, it was revealed that the British public are currently overspending by over £800 million on their energy bills. A prepayment meter can be a useful way to take control of your energy usage. But it’s important to know who the best prepayment providers are. In this article, we will cover just that so you can be more informed on how to manage your energy bills properly and, not to mention, save money!

Last update: November 2022

Why are we overpaying so spectacularly for the energy we use?

In many cases it’s because we’re on the wrong tariff for our needs. Something we need to be wary of, even with the best prepayment providers. Although the UK energy industry regulator Ofgem has placed a cap on how much suppliers can charge for energy in any given year, the simple truth is that too many of us are paying too much for our gas and electricity. When we fail to take control of our energy usage and spend, energy costs can easily escalate. Which is why many who worry about overspending on their energy prefer to use a prepayment meters. In this post we’ll take a look at some of the benefits and caveats of prepayment energy and take a look at some of the best prepayment providers and tariffs.

Are you overpaying for your energy? Let us help you out with that!When you call the number on the top of the screen, our experts can help you find the best energy deal (and possibly save you up to £400 a year!)

What is a prepayment meter?

A prepayment meter is a meter that needs to be topped up before it will supply energy to your home. Instead of paying a monthly direct debit, you pay for the energy you use on a Pay-As-You-Go basis. In essence, using a prepayment meter is just like having a mobile phone on a prepayment contract. Once your meter is set up, you’ll receive a card or key. This can be topped up at your local newsagents, corner shop, post office, petrol station or anywhere else you see the Pay Point logo. Alternatively, you can top up your account over the phone, online or using your supplier’s mobile app if they have one.

Prepayment meters can be used for both electricity and gas, and most energy suppliers in the UK have at least one prepayment tariff.

The benefits of prepayment meters

There are many energy consumers in the UK who are wary and mistrustful of direct debits. All too often, energy suppliers can bill us based on our estimated use. And this can lead to unnecessary expense. Which is why it’s so important to take monthly meter readings when you’re on a conventional credit meter. Estimated meter readings can be based on historic energy usage in your area, which may near absolutely no relation to your personal usage.

The good thing about a prepayment meter is that it puts you in the driving seat. Because you add credit to your account then spend it accordingly in energy usage, you know that you’re only ever paying for the energy you use.

Let’s take a look at some of the potential benefits of prepayment meters:

  • Much less chance of inaccurate bills or billing errors.
  • No unpleasant surprises because your energy use is capped.
  • For some, it’s easiest to top up a prepayment card or key than rummage around in the meter cupboard to check for a reading.
  • You know that you’re only paying for what you use.
  • You feel in control of your energy supply.

The potential disadvantages of prepayment meters

With the right prepayment provider and tariff, you may find that a prepayment meter is advantageous for your circumstances. However, there are also some inherent disadvantages to prepayment meters that should be factored in so that you can make a truly informed choice.

  • You will experience a loss of service if you run out of credit.
  • There are fewer tariffs available than those with credit meters enjoy.
  • Although rare, billing mishaps do happen with prepayment meters. For instance, this man woke up one morning to a £19,000 energy bill despite being on a prepayment meter.
  • You’ll almost certainly end up paying more for your energy per kilowatt hour (kWh). More on that later!

Can my supplier force me to use a prepayment meter?

It’s rare, but in some cases energy suppliers may force customers to switch to a prepayment meter if they have amassed significant energy debts. However, Ofgem discourages this practice and has banned forced installations for the most vulnerable energy consumers as of 2018.

While some genuinely find a prepayment meter easier to manage, it needs to be your choice to use one. Furthermore, some energy consumers will not be able to top up their prepayment meters as easily as most.

The Citizens Advice Bureau has some useful advice on what to do if your supplier tries to force you to use a prepayment meter against your will.

Do prepayment meters cost more?

If you’re using a prepayment meter, you may feel more in control of your usage. Unfortunately, you’re almost certainly paying more than you could be paying on a direct debit tariff with a conventional credit meter.

Energy companies are just like any other businesses. They need to ensure a steady cash flow to ease their operations. And it’s easier for them to maintain their cash flow if they know that they’re going to get a set amount from every customer every day. As such, it’s in their best interests to incentivise direct debit tariffs, offering those customers the best rates.

If we take a look at some of the best prepayment tariffs on the market at present, it would seem to corroborate this theory:

Supplier Name Tariff Name Price
Bulb Vari-Fair £1024
EDF Prepay Total Service May22 £1041
SSE Standard Pay As You Go £1065
E.On E.On Energy Plan with Prepayment £1069
SSE Standard (Variable) Prepayment £1069

The above prices are based on dual fuel prepayment tariffs with medium usage averaged out across the UK. Exact prices may vary depending on your location, energy needs and usage.

Now let’s apply the same criteria to direct debit tariffs with conventional credit meters:

Supplier Tariff Name Tariff Type Price
E.ON Fix Online Exclusive v51 Fixed for 12 months £875
Green Network Energy GNE Summer Sizzler V9 Fixed for 12 months £876
Avro Energy Simple and USelect12M Fixed for 12 months £883
OVO Energy Better Smart Fixed for 12 months £889
Shell Energy Energy January 2022 v3 Fixed until 31 Jan 2022 £890

As we can see, even the bottom tariff on this list is significantly cheaper than the top prepayment tariff from Bulb.

Which is why it’s so important to be discerning in your choice of energy supplier and tariff, no matter what kind of meter you’re using. If you choose an advantageous tariff on a prepayment meter you may still be paying much less for your energy than those with a standard credit meter who are on a standard tariff or “deemed contract” with their energy supplier.

Prepayment meters and the energy price cap

As of January 2019, Ofgem have placed an upward cap on how much energy suppliers can charge their customers in any 12 month period. As of October 2020, this cap is set at £1,042. This is actually the lowest it has been since the cap was first introduced.

However, there also exists a separate price cap for prepayment meters. This is known as the “safeguard tariff” or prepayment price cap, and restricts how much prepayment providers can charge their customers for each kWh of energy.

According to Ofgem, however, over 90% of prepayment meter customers are on tariffs that are close to this limit. Which is why it’s even more important for prepayment customers to get the best deals.

Can I change prepayment providers if I have a prepayment meter?

You can and you should.

Just like any other energy consumer, you owe it to yourself to keep changing supplier regularly and keep an eye on the markets to ensure that you’re getting the best value for money. While there are fewer prepayment tariffs on the market than direct debit tariffs, you still have a huge range of prepayment providers and tariffs to choose from.

Let’s take a closer look…

Why is prepayment more expensive?

Prepayment meters represent more risk and instability for energy suppliers. As such, they tend not to offer the kind of favourable rates that customers with direct debits enjoy when they search the market for the best tariffs.

Still, that doesn’t mean that you can’t save money on a prepayment plan. The right prepayment providers and tariff will still work out cheaper than remaining on a standard or default tariff with a conventional credit meter.

Can I change supplier with a prepayment meter?

Yes, absolutely! What’s more, you should keep checking the market to ensure that you’re always getting the best value for money. Of course, we’re always close by to scour the market on your behalf and bring you the best deals from the best prepayment providers. 

Can I change from a prepayment meter to a credit meter if I change my mind?

Assuming that you do not have outstanding debts of over £500, you will probably be able to change to a conventional credit meter of you decide that a prepayment meter isn’t for you. If you’re with one of the “Big 6” suppliers, you’ll even be able to do this for free. However, some suppliers may charge a small fee for changing your meter. Always check with your supplier as this fee may impinge on your future savings.

Who is the cheapest prepayment energy supplier?

That really depends on your usage, your location, and whether you have single or dual fuels. However, customers tend to rate the following prepayment providers highest in terms of value for money:

  • Bulb 
  • Octopus Energy
  • Ebico
  • People’s Energy
  • Pure Planet
  • SSE
