Should I Fix My Energy Tariff?

Stuck on energy tariffs? Should you fix your energy tariff? Choose a tracker or a standard variable one. And if you do fix, for how long?

Trying to figure out the best gas and electricity deals can be a bit of a headache! If you're thinking of renewing or changing your energy tariff, it's worth noting that Ofgem’s price cap from 1 April will be £1,641 a year for a typical dual‑fuel household paying by Direct Debit. This is 7% decrease from the January to March cap. But as we head into spring, you may want to look for a new energy deal.

This new lower price cap includes the Government’s £150 energy bills discount, which is applied automatically through reduced unit rates. Importantly, this discount applies regardless of whether you’re on a fixed, tracker or standard variable tariff, so you’ll benefit whichever option you choose.

31 March is National Meter Read Day, when energy companies collect readings from some customers, and falls the day before the price cap changes for those on variable energy tariffs, on 1 April.

If you're already on a fixed deal, these changes to the price cap won't affect you.

It’s still a good idea to check you’re on the best tariff for your needs and see if you could save.

What is a fixed energy tariff?

A fixed energy tariff is a type of energy plan that locks in your gas and electricity price for a defined length of time, typically one or two years. Unlike variable energy tariffs, which shift costs when the wholesale energy market changes, fixed-price tariffs give stability and price certainty. Looking to fix before a quarterly price cap change is a good idea, particularly when facing uncertainty in energy prices and predicted price rises.

With more and more UK households choosing to fix their tariff, rising from around 7 million in 2024 to roughly 21 million as of Ofgem’s latest data in February 2026, this sort of tariff is becoming increasingly common.

But is fixing your energy tariff the right choice for you?

Should I switch to a fixed energy deal?

The decision to switch energy deals depends on how you or your household use energy and money:

On a fixed tariff, your unit rate stays the same for your whole contract, so your bills only rise if you use more energy. On a variable tariff, your bills can rise both because you use more energy and because your unit rate may change with wholesale prices.
Some people like fixed-priced tariffs as it helps them budget their monthly household costs
There may be a cost difference, for example, many fixed priced tariffs are actually cheaper than the capped price; so fixing could be your cheaper option

Fixed energy tariffs

With a fixed-price tariff, or plan, you pay a set unit price over the lifetime of your gas and electric contract. It helps you budget better and gives you peace of mind because the unit price doesn't change when energy prices go up, meaning you could secure today’s lower rates and avoid potential increases, making it cheaper than our standard prices when this happens.

What are the benefits of a fixed energy tariff?

Price certainty: You know exactly how much you’ll pay per unit of electricity and gas - this helps with budgeting
Protection from price rises: If energy prices go up, your fixed-price rate won’t change during your contract period
Peace of mind: No need to worry about your bill suddenly going up due to energy market changes

Exit Fees: Will you have to pay an exit fee if you leave your contract early?
Renewable options: Some fixed tariffs offer zero carbon alternatives

Can I have a single fuel fixed energy tariff?

Yes, you're in complete control of your energy. For example, you can choose to have your electricity on a fixed-price tariff and your gas on a variable tariff. The important part is finding the right tariff to suit your household's needs.

Does it make a difference if I fix my energy if I rent, own my home, or am a student?

Yes, your housing situation (renting, owning, or being a student) can make a difference - not about the price, but more about the process of buying energy.

Fixing your energy if you rent your home

Are your bills included in your rent? If it's your landlord who is in charge of the energy bill, you won't have the right to switch tariffs as they're the energy customer, not you
Rent and pay your bills separately to your rent? As the energy customer, you've the right to switch tariffs or suppliers. Just make sure to consider the length of your tenancy agreement, as fixing for a long period, for example, an 18-month energy contract for a 12-month tenancy, might result in you paying exit fees, if you need to move out before your contract ends

Fixing your energy if you own your home

As a homeowner, you have control over your energy supply and can choose any tariff from any supplier, switch when you want (subject to exit fees and if you owe the energy company any money), and make long-term decisions about energy contracts.

Fixing your energy if you're a student

Live in halls of residence? Your energy bills are most likely included in the rent, so you'll have no control over who supplies your energy or tariff
Shared student housing: In this instance, it's the same as renting - but make sure you sort out bills as soon as possible with your housemates and get everyone's name on the bill to share legal responsibility
Get a competitive deal: Shopping around for the best deal is a priority, and fixing your tariff may be a good solution, but check how long the tariff lasts for, versus how long you'll be living in the house

What is the energy price cap?

Ofgem (the government energy regulator) introduced the energy price cap to limit the unit rates people pay in the UK for gas and electricity. The energy price cap is reviewed every three months and it's only variable or tracker tariffs which change price in line with the price cap. Prices can go up or down, depending on lots of factors such as supply and demand, global politics and supply chain problems. Fixed-rate tariffs work separately to the cap, and remain the same price for the length of contract.

When are the price cap periods?

Ofgem review their price cap every three months, there are four periods during the year:

1 January - 31 March
1 April - 30 June
1 July - 30 September
1 October - 31 December

Ofgem's April price cap is set at £ 1,641 and lasts from 1 April 2026 to 30 June 2026.

If you're not sure what the current price cap rate is, you can learn more about price cap as well as our future price cap predictions.

Should I fix my energy?

The short answer is: It depends! Prefer more flexibility and are happy to accommodate changing prices? Then a variable or tracker tariff might be right for you. Or, if price security and budgeting for the future is more important, then a fixed tariff could be your best option. If a fixed tariff isn’t the cheapest option at the time, think about whether you’d prefer to pay slightly more to guarantee your energy costs won’t go up. If you're worried, to get a better idea of energy costs, compare our tariffs against Ofgem's price cap.
