Should I switch energy supplier?
The energy market has been volatile lately, but you may be able to save by switching supplier.
If you’re on a variable rate tariff, the amount you pay for your energy is influenced by the energy price cap. The current price cap for a typical household is £1,849 per year, but this will drop by 7% to £1,720 from 1 July.
With the price cap set to fall, it could be a good time to assess your options and consider switching to a fixed deal, which will lock in your rate for a set period - for example 12 months. Comparing deals with Compare the Market takes just 2 minutes[1].
If you’re already on a fixed deal, the price cap change won’t have any impact on how much you’ll pay for your energy.

How to compare energy and switch supplier
It all happens in just three simple steps:
- Give us your postcode: We’ll show you an estimate of your energy spend and usage compared to your neighbours. Update anything that doesn’t look right.
- Compare deals: We’ll show you a list of deals that may be available to you. You can filter it by tariff type, fuel type and more.
- Make the switch if you want to.
If you decide the time is right to switch, just provide a few details about yourself, including your name, contact number and payment details. Your energy supplier will take care of the rest.
How do I know which supplier is right for me?
There are a few factors you might want to consider when deciding whether an energy supplier is right for you:
- Is the deal it is offering below the energy price cap?
- Do you want to switch to a fixed-rate deal?
- Does the provider have a good reputation for customer service?
- What’s the company’s record when it comes to green energy and renewables?
- Does the provider charge exit fees if you leave a tariff early?
How long will it take to switch energy suppliers?
It should take no longer than five working days to switch energy suppliers under the Energy Switch Guarantee.
What happens when I switch?
Your gas and electricity supply will carry on as normal when you switch energy suppliers. The only thing that changes is where your bills come from.
What if I change my mind about switching?
You’ll have a 14-day cooling-off period, starting from when you agree your new contract. You can cancel without a penalty during this time.

What is the energy price cap?
The energy price cap is a limit on the unit rate and standing charge that suppliers can charge for their standard variable tariffs. The cap is set by the UK’s energy regulator, Ofgem.
The price cap from 1 April to 30 June 2025 is set at:
- £1,849 for those paying by direct debit
- £1,803 for those with a prepayment meter
- £1,969 for those who pay on receipt of their bill.
From 1 July to 30 September 2025, the cap will be set at:
- £1,720 for those paying by direct debit
- £1,672 for those with a prepayment meter
- £1,855 for those who pay on receipt of their bill.
However, this doesn’t mean this is the maximum you’ll pay. The size of your bill depends on how much energy you use, where you live and how you pay. If you use more than the average household, you’ll pay more than the price cap.
The energy price cap doesn’t apply to households in Northern Ireland.
Why are energy prices so high?
Energy prices have remained high compared with pre-pandemic levels, and July's price cap decrease will still result in costs being higher than a year ago.
This can make finding the cheapest energy supplier tricky. The good news is that providers are offering more competitive deals than before, making switching more attractive.
Will energy prices go down in 2025?
From 1 July, the energy price cap will be set at £1,720, a decrease of £129 compared to the cap set between 1 April and 30 June. The new price cap will be in force until 30 September. The outlook for energy prices from October onwards is uncertain, though significant rises or falls appear unlikely.
You can see the recent history of the energy price cap in the table below:
| Quarterly update period | Price cap level |
| 1 July to 30 September 2024 | £1,568 |
| 1 October to 31 December 2024 | £1,717 |
| 1 January to 31 March 2025 | £1,738 |
| 1 April to 30 June 2025 | £1,849 |
| 1 July to 30 September 2025 | £1,720 |
One of the best ways to find the cheapest energy supplier is by shopping around. Compare energy prices with Compare the Market to see if you can get a better energy deal.
How to save on your energy bills in the home
As well as comparing energy prices and choosing a cheaper tariff, you could also lower your bills by reducing the amount of energy you use. Here are a few quick wins:
Adjust your boiler flow setting
If you have a combi boiler, the default flow temperature is normally set at around 70°C to 80°C. Reducing it to 60°C or lower could reduce your bills.
Turn down your thermostat
Lowering the temperature of your heating by just 1°C could have a real impact on your energy bills over the course of a year. But don’t go below 18°C as this could be potentially harmful to health.
Use an air fryer instead of an oven
Air fryers are compact so don’t take as long to heat up as ovens. That means cooking times are considerably reduced.
Wash clothes at lower temperatures
Today’s washing detergents are very effective at 30°C, so try to avoid washing laundry on a higher setting.
Don’t charge your phone overnight
Most smartphones charge fully in under three hours. So you’re wasting energy by keeping them plugged in while you’re asleep.
Take your appliances off standby
Turning your appliances off at the plug could save you around £45 a year in electricity. But be careful not to switch off any gadgets that need to be left plugged in, such as your digital TV box.
Keep the heat in
Draught-proof your doors and windows, and insulate pipes, radiators and your water tank.
Avoid estimated bills
If you don’t have a smart meter, send regular meter readings to your supplier. That way, your direct debit will be set at the right amount and you’ll pay for what you use.

What support is available if I’m struggling with my energy bills?
Ofgem rules state that all energy suppliers must have plans in place to help customers who can’t afford to pay their bills.
These rules mean suppliers must offer payment plans that customers can afford. And you can ask for ‘emergency credit’ if you use a prepay meter and can’t afford to top up. There are also grants available to some customers to help with energy bills.
If you’re having difficulties, contact your energy supplier as soon as possible. If you’re worried about what to say, take a look at this MoneyHelper guide to talking to your creditor.

Why switch gas and electricity providers?
There are several reasons to do an online gas and electricity comparison and consider switching your energy supplier:
Getting a better deal
Carrying out an energy price comparison and evaluating suppliers each year can potentially save you money on the cost of your gas and electricity.
Compare the Market is constantly monitoring the energy market so you can compare energy deals that might be right for you.
Better service
Even if you’re on a lower-cost contract already, you may be unhappy with your energy supplier’s service. Switching to a supplier with better customer service could fix this.
Greener energy
You might want a supplier that uses more renewable energy. With roughly 46% of the UK’s energy supply coming from renewables in 2023, green suppliers could soon offer some of the cheapest energy deals.
Which tariff is best for me?
It depends on what you want from an energy deal and your financial situation. There are several types of energy tariffs:
- Dual fuel – getting gas and electricity from the same supplier can be the cheapest option. It also means you’ll only have one bill to deal with.
- Green energy – if you want to reduce your carbon footprint, look at energy suppliers who specialise in wind, solar or other renewable sources to offset their carbon usage.
- Variable tariff – these tariffs fluctuate according to the market. So if prices go up, you’ll pay more. If they fall, you’ll save.
- Fixed rate tariff – these tariffs can make budgeting easier as the unit price of energy is fixed for a set period.
- Prepayment energy tariff – with a pay-as-you-go energy meter, you pay in advance for the gas and electricity you use.
- Economy 7 tariff – an Economy 7 tariff can give you a cheaper rate for electricity during ‘off-peak’ hours, usually at night.
- Electric vehicle (EV) energy – allows you to charge your electric car for a reduced unit rate at specific times of the day, typically for a few hours overnight
- Time-of-use tariffs (or TOUs) – you pay different amounts at different times. Electricity is cheaper when demand is lower, and pricier at more popular times
Can I compare gas and electricity prices separately from gas prices?
You can compare gas and electric quotes separately or together. While dual fuel is a popular way to keep your energy bundled together, you can also get gas and electricity from different providers.
Can I switch to a better deal?
Energy prices remain high, so it’s a good idea to compare different energy suppliers to get the cheapest energy tariff for you.
Compare energy suppliersFrequently asked questions
How often do energy prices change?
Energy prices reflect market supply and demand and constantly fluctuate as a result. They’re also affected when wholesale costs change.
The current Ofgem energy price cap is set every three months. This reflects inflation as well as other underlying costs of energy.
Ofgem caps the unit price of gas and electricity for a typical household with a dual-fuel tariff, paid by direct debit.
But the amount you pay altogether will still depend on how much energy you use.
What’s the cheapest way to pay for gas and electricity?
The cheapest way to pay your gas and electric bill is usually via direct debit.
Where can I get the cheapest gas and electric?
This depends on whether you choose a fixed tariff or a price-capped tariff. Ultimately, the best way to save on gas and electricity is to shop around for cheap energy deals.
What is the difference between fixed and variable-rate tariffs?
The difference between a fixed and variable rate tariff is the unit cost. Fixed-rate tariffs will stay the same for an agreed length of time.
With variable tariffs, the unit cost can go up or down in line with changes in the wholesale energy market.
Is it easier to switch gas and electricity together?
Switching dual fuel or switching one energy type on its own are both simple when you use Compare the Market.
The only potential complication would be if you’re on a fixed-term contract that hasn’t yet expired. In this case, you may have to pay an exit penalty.
Can I switch energy supplier if I owe money?
If you have bills that are more than 28 days old, you might find that you can’t change energy supplier until you’ve paid them. But there are some exceptions.
If you’re on a prepayment meter and you owe money, for example, the energy supplier you switch to will take on the debt and you repay them instead.
How can I switch gas and electricity when moving home?
If you’re moving house and your existing deal is a good one, your energy supplier might let you move it to your new home. Just give them your new address and the moving-in date.
On moving day, take a meter reading before you leave and give this to your supplier. This way, you can be sure your final bill will only reflect what you’ve used.
Be sure to also take a meter reading at your new home straight away too, so you won’t be paying for energy used by the previous owner.
Can I switch energy provider if I rent?
Tenants can switch energy providers if they pay the supplier directly for their gas and electricity.
If your landlord pays your energy bills then charges you, choosing the energy supplier is up to them. Although you can always ask them if it’s possible to switch to the cheapest energy supplier.
Can I get a smart meter if I switch gas and electricity?
Probably. Since January 2022 all gas and electricity suppliers have had binding annual installation targets to roll out smart and advanced meters to their remaining non-smart customers by the end of 2025. Energy companies continue to work towards this target.
You can ask your current energy supplier for a smart meter and they’ll let you know if it’s possible to get one and when. It may take a while to book an appointment as the suppliers try to meet the deadline.
Some suppliers may offer beneficial tariffs for smart meter users.
How can I find a green energy supplier?
When you compare energy suppliers with Compare the Market, you’ll be able to see tariffs for 100% renewable energy.
