Cheapest UK fixed energy tariffs — July 2026
All of the deals below undercut the £1,663 Ofgem price cap for a typical dual-fuel direct-debit household. Figures are typical annual costs and move with the market — availability can be withdrawn quickly, so the headline rate you see today may not last.
the Ofgem price cap: what's changing
Figures are GB direct-debit averages; regional and payment-method variations apply. A fixed tariff taken out now protects you from this increase for the length of the fix.
What happens when a fixed energy deal ends in the UK?
For most UK homes, when your fixed tariff reaches its end date you'll typically be moved to your supplier's standard variable tariff (SVT), which tracks the Ofgem cap. Your supply continues as normal — the main change is the unit rate and standing charge you pay, and from 1 July that SVT is +13% higher.
You won't be cut off
Your gas and electricity keep running. Ending a fixed tariff is a pricing change, not a supply interruption.
Costs are rising from July
Key terms to know (quick glossary)
- Fixed tariff: unit rates (and sometimes standing charges) are fixed for a set period.
- SVT (standard variable tariff): price can change with the cap; the default when your fix ends.
- Standing charge: a daily charge for being connected to the network.
- Unit rate: the price per kWh of gas or electricity you use.
Why compare with EnergyPlus?
With the cap rising on 1 July, the goal is simple: lock in a tariff that fits your household before today's best fixes are withdrawn. EnergyPlus is built around that decision.

Clear, UK-specific guidance
Understand SVT vs fixed, exit fees, the current cap and what can affect prices in your region.
Designed to reduce hassle

Good to know: Switching is free and usually completes in around 5 working days — and you can switch even without a smart meter. Tariff availability can depend on payment method, meter type (including smart and prepayment), and whether you want dual fuel or electricity only.
How switching works when your fixed tariff is ending
Switching energy supplier in the UK is usually straightforward and free, typically taking around 5 working days. Your gas and electricity supply stays on; what changes is the company billing you and the tariff you're on.
- Check your end date and any exit fee window. Some fixed deals have exit fees if you leave early. Many suppliers waive the fee near the end of the contract — check your terms.
- The cheapest 12-month fixed deals on our live panel are typically priced below the £1,663 cap, several with no exit fees — run your postcode through the comparison on this page for today's exact prices.
- Choose the right structure. A fixed tariff locks your rate and protects you from the July rise; a zero-exit-fee fix like Octopus also keeps you flexible.
- Start the switch. You'll be asked for basic details. Your new supplier handles most of the process — no smart meter required.
- Take meter readings. Provide readings (or smart meter data) around the switch date to help ensure accurate final and opening bills.
What can affect which tariffs you see?
- Your postcode (regional network charges)
- Your meter type (credit, smart, prepayment)
- Payment method (e.g., Direct Debit)
- Whether you need economy/complex tariffs (where applicable)
- Any debt on your current account
- Green tariff preferences
Best time to act if your fixed deal ends soon
With the cap rising +13%, acting sooner protects more of your budget. Timing also matters because you may want to avoid early exit fees while limiting time on a higher SVT. The right moment depends on your contract terms and the deals available when you compare.
Reminder: If you're unsure about exit fees, check your welcome email, tariff terms, or your online account. If you tell us your end date, we can factor it into your options.
Common mistakes when a fixed energy tariff ends
Waiting until after 1 July
The cap rises +13% on 1 July. Today's best fixes can be withdrawn at short notice, so comparing now locks in a better rate.
Ignoring standing charges
Low unit rates can be offset by higher standing charges. Always look at both when you compare.
Assuming one tariff suits everyone
Household usage patterns differ. A tariff that works for a low-usage flat may not suit a larger home.
Forgetting meter readings
Accurate readings reduce billing issues at the switch point — especially if you don't have a smart meter.

FAQs: fixed energy tariff deals ending soon (UK)

Can I switch before my fixed tariff ends?
Often yes, but there may be an exit fee if you leave early. Check your tariff terms. Some suppliers waive exit fees near the end of a fixed deal, depending on the contract.
Is a fixed tariff always better than a variable tariff?
Does my postcode affect energy prices?
Yes. Network costs vary by region, which can affect standing charges and unit rates. That's why a tailored comparison uses your postcode.
