Compare fixed and variable electricity-only tariffs
If your home uses electricity rather than gas for heating, then you're likely on an electricity-only tariff.
Alternatively, if you want your gas and electricity to come from different suppliers, you can search for gas or electricity-only tariffs individually, rather than get a dual fuel deal from a single energy supplier.
You can still compare electricity-only tariffs.
If you want the convenience of a single bill, then consider switching to a dual fuel tariff instead.
Switching won't interrupt your supply, so you can change suppliers with confidence knowing you'll still be connected to the grid.
You could be with your new supplier within five working days – with no interruption to your service. Everything is handled by your new provider, so all you need to do is compare and go.
Give us your postcode and tell us about your energy usage – your most recent bill will give you the best results.
We’ll search the market and show you what you get if you switch suppliers.
Once you’ve started your switch you won’t need to do a thing – your new provider will take care of everything.

There are normally so many suppliers, tariffs and prices on the market, the choice of energy deals can sometimes be overwhelming. It’s simpler than you might expect, however. There are six main types of electricity tariff available – you can pick from the following:
A fixed-price electricity tariff has a set price for each unit of electricity you consume, so your bill only changes as your consumption does. You’ll need to sign a contract to access this tariff.
Fixed tariffs protect you from price hikes, but you’re locked in if prices fall – and there are often exit fees if you want to leave early.
Sometimes known as a standard variable tariff, this is the most popular type of electricity tariff. The cost of each unit changes with the electricity market, but there’s no contract and no exit fees.
If you’re on another tariff, most suppliers will automatically switch you over to a standard tariff when your existing contract runs out.
A dual fuel tariff means you get both your electricity and gas from a single supplier. This can be convenient, as there is only one point of contact to manage all your energy.
Dual fuel tariffs can be either fixed or variable, and suppliers may offer discounts if you choose to buy both electricity and gas from them.
Green energy tariffs guarantee that at least some – but usually most or all – of your energy comes from renewable energy sources – such as solar, wind or tidal power.
These tariffs can also be either fixed or variable, and in recent times they’ve started to become cheaper than non-green tariffs.
Prepayment tariffs let you pay for your electricity in advance. You top your meter up online, or using a card or key, making them a good way to manage the exact amount of energy you use.
You generally pay more per unit than on other tariffs – and there’s always the risk that the meter will run dry at an inconvenient time.
Economy tariffs work like standard variable tariffs, with one main difference: unit prices are cheaper at night. They reward people who are prepared to run appliances after a certain time.
The price per unit can go up or down depending on the market, but there are normally no early exit fees or contracts to sign.
To superpower efficiency and slash your bills further, you can make a few changes around the home.
The Energy Saving Trust estimates that turning appliances off at the plug will save the average household up to £80 a year. You can use cheap timer plugs to schedule when your appliances go off.
Throwing out a perfectly good appliance won’t save you money, but when it is time to swap, go for one with a high energy-efficiency rating. An A+++ fridge freezer will save around £320 in energy bills over its lifetime compared to an A+ model.
Washing at 30 degrees rather than 40 degrees can help reduce your energy usage, and if you can cut out one wash cycle per week you’ll clip £5 off your annual energy bill.
Keeping a watchful eye on your consumption levels can help you decide if and when you have to change the way you use energy. A smart meter will track your consumption with accurate information.
While waiting for the opportunity to switch to a better deal, understanding how much electricity your household is using and where you might be able to cut back could also be a way of lowering your bills. The more you understand about fixed and variable tariffs and your own energy consumption, the more informed a decision you can make when it comes to potential switches.

Most of the country’s energy comes from the Big Six, the six biggest energy suppliers in the UK. These are:
British Gas
EDF Energy
E.ON
Npower
Scottish Power
OVO
However, there are an increasing number of smaller providers, such as First Utility, Octopus Energy and Ecotricity. They may not be as well-known as the ‘Big Six’ companies, but they do offer certain advantages:
Some smaller suppliers specialise in green energy
Many also come out on top for customer service, compared to the Big Six
Yes, there are. A number are available from the government or your local council, provided you qualify – usually if you are claiming certain benefits.
These schemes include the Warm Home Discount, Cold Weather Payments, and Winter Fuel Payments for pensioners.
Some suppliers also run their own schemes for customers who are struggling, such as British Gas’ energy grants. Contact your supplier for more information on these.

Finding an energy tariff for your business is slightly different to domestic energy. You can request a call back from our energy experts, or call them yourself on 0800 088 6986, and discuss your requirements so you can find the right business energy deal for you.
If your bills are included in your rent, or if your landlord rebills you for electricity costs, then it’ll be up to them to arrange your electricity supply. You can always ask them to switch energy supplier if you have a preference, or you could ask to arrange it yourself.
Whether you’ll be able to get a smart meter will depend on your provider and when they plan to roll them out in your area – they may be available already. It’s best to contact them directly to make an enquiry.
Learn more about smart meters and how they work with our guide.
Switching energy suppliers is quick and easy thanks to the energy switch guarantee. The whole process is taken care of by your new provider, and you won’t be without energy at any point. If there are any issues, your provider will try to resolve them as soon as possible. And if you choose to fast track your switch, you should be with your new supplier in just five working days.
Comparing energy tariffs with MoneySuperMarket's energy comparison tool is the easiest way to switch suppliers. All you need to do is tell us a little about yourself, your home, and your approximate energy usage – the more accurate you can be, the more accurate your bills will be.
We’ll show you a list of quotes from the ‘Big Six’ providers, as well as smaller providers. Once you find the deal you want, just click through to the provider to finalise your switch.
You’ll be able to switch from a prepayment meter to a credit meter if you aren’t in debt to your current provider – but you might need to undergo a credit check.
Some suppliers might charge a fee to change your meter, but not all will.
Between 1stJuly and 30th September 2025, the energy price cap has been set at £1,720 per year for a typical household who are on dual fuel standard-variable tariffs and who pay by direct debit.
This represents a decrease of 7% from the last cap set between 1 April to 30 June 2025 (£1,849).

We get paid by the companies we work with, but the payment we get doesn’t have any bearing on the information we provide. We get paid in different ways, depending on the type of product or service you buy through us. Our goal is to search deals from as wide a range of companies as possible, but we only show results from our partner providers.

We don’t give recommendations or financial advice, but we give you clear information so you can choose financial products that suit your circumstances.
No, not every company can be included in our service. This is because some companies don’t want their products included on comparison sites, and some decide that they would rather not pay a fee. There are also a few smaller providers who can struggle to cope with the volume of customers that can find their products if they appear on MoneySuperMarket.
