What are fixed energy tariffs for UK homes in 2026?

A fixed energy tariff is a contract where your unit rates and standing charges are locked in for a set period, typically 12–24 months. For 2026 UK home energy deals, a fixed tariff protects you from future price rises during the contract. Your monthly bill can still vary based on how much gas and electricity you use, but the price you pay per kWh stays the same until the end of the fix.

How do I choose the best fixed energy tariff for 2026?

To choose the best fixed energy tariff for 2026, start by entering your postcode and usage on EnergyPlus so we can tailor results to your home. Compare the annual estimated cost, the unit rate per kWh, standing charge, contract length and whether there are exit fees if you want to switch early. Also consider payment method (direct debit is usually cheapest), online account management, and whether the tariff includes 100% renewable electricity. Picking the lowest overall annual cost from a reputable supplier is often the best option for most households.

Are fixed energy tariffs cheaper than variable tariffs in 2026?

Whether a fixed energy tariff is cheaper than a variable tariff in 2026 depends on wholesale market conditions and your usage. Fixed tariffs can look slightly higher than the cheapest variable deals today but protect you from future price rises, which can save money over the contract term. Variable tariffs may be cheaper initially but can increase at short notice. When you compare on EnergyPlus we show the projected annual cost of both fixed and variable options so you can see which looks better for your household right now.

How long should I fix my energy tariff for 2026?

Most UK fixed energy tariffs in 2026 run for 12, 18 or 24 months. A 12-month fix offers more flexibility to switch again next year, while longer fixes can give extra price security if you are worried about bills rising. When you view deals on EnergyPlus, you can filter by contract length and see exactly when your fixed tariff will end, helping you balance stability against flexibility.

Can I switch to a 2026 fixed tariff now?

Yes, in most cases you can switch to a 2026 fixed energy tariff at any time, even if you are currently on a standard variable tariff. If you are already in a fixed contract, check for exit fees before switching early. EnergyPlus guides you through the switching process, shows any potential exit charges and helps you choose the most competitive 2026 fixed deals available for your property. The switch is handled by your new supplier with no interruption to your gas or electricity supply.

Do 2026 fixed energy tariffs have exit fees?

Many 2026 fixed energy tariffs include an exit fee if you leave before the end of the contract, typically charged per fuel. However, some suppliers offer fixed deals with low or no exit fees to give you more flexibility. When you compare tariffs on EnergyPlus, exit fees are clearly shown so you can factor them into your decision before you switch.

Are there green or renewable fixed energy tariffs for 2026?

Yes, several UK suppliers offer 2026 fixed tariffs that include 100% renewable electricity or a high percentage of green energy. These tariffs work in the same way as standard fixed deals but your supplier matches your electricity usage with power from renewable sources such as wind or solar. On EnergyPlus, you can filter by green or renewable tariffs and compare them directly with other fixed-rate offers for 2026.

How fixed home energy tariffs work in 2026

A fixed home energy tariff means your unit rate for gas and electricity, and often your standing charge, stay the same for an agreed term. In 2026, most UK suppliers will continue to offer fixed deals from 12 to 24 months, giving households certainty over their monthly bills.

Price security

Once you agree a fixed tariff, your unit rates are protected from market rises for the length of your contract, helping you budget with confidence.

Same gas & electricity, new price

The way energy reaches your home doesn’t change. You simply pay your new supplier at the agreed fixed rate for your usage.

Exit fees & flexibility

Some 2026 fixed tariffs include an exit fee if you leave early, while others are fee-free. We highlight both options in your results.

Fixed tariffs are often a smart choice when wholesale prices are expected to rise, or if you simply prefer predictable bills. However, if market prices fall significantly, you might not benefit unless you switch again. That is why comparing suppliers regularly is essential.

Best UK home energy suppliers for fixed tariffs in 2026

The best fixed-tariff energy supplier for your home in 2026 depends on where you live, your annual usage, meter type and whether you prefer green energy. Below is an overview of the main UK home energy brands expected to offer competitive fixed deals, along with the features many households look for.

Strong customer support and well-developed apps
Choice of 12-month and 24-month fixed home energy plans
Bundled services such as boiler cover or home care

What to look for in a 2026 fixed tariff

When comparing the best UK home energy suppliers for fixed tariffs in 2026, don’t just focus on the headline rate. The right deal balances price, contract length and flexibility. Use the checklist below to help choose a tariff that works for your household.

Feature	Why it matters	What to check
Unit rate (p/kWh)	The price you pay for each unit of gas or electricity used.	Compare unit rates against the price cap and other fixed deals in your region.

Contract length	How long your fixed prices are guaranteed for.	12 months for flexibility, or 24 months for long-term price security.
Exit fees	What you pay if you leave the tariff before the end date.	Look for low or zero exit fees if you want the option to switch again.
Green energy	Whether your electricity is matched with renewable generation.	Check if the tariff offers 100% renewable electricity or carbon-offset gas.
Smart meter support	Enables accurate, automatic readings and smart tariffs.	Confirm your chosen supplier can support your existing smart meter.
Customer service rating	How satisfied existing customers are with billing and support.	Look for high review scores and UK-based support where possible.

Is a fixed home energy tariff right for you in 2026?

Whether fixing is right for your household depends on your appetite for risk and how you use energy. A well-priced fixed deal can shield you from sudden price rises, but may not always be the absolute cheapest option if wholesale costs fall.
