Best two year fixed energy deal UK (May 2026): how to compare & decide
Two-year fixed energy deals give you 24 months of certainty on your unit rates and standing charges. They suit homes that prefer predictable bills over chasing the lowest possible rate. In May 2026 the gap between cap-linked tariffs and the cheapest fixes is small but persistent — meaning a careful comparison can still pay off.

Two-year fixed deals in May 2026 — the key facts
A typical UK household using 2,700 kWh of electricity and 11,500 kWh of gas (Ofgem's median dual-fuel profile) will pay slightly more upfront on a 24-month fix than on the prevailing cap, in exchange for protection if Ofgem raises the cap in the next four quarters. The cheapest 24-month fixes are typically within 3–8% of the cap.
Quick checklist (May 2026):
- Locks unit rates and standing charges for 24 months across gas & electricity.
- Exit fees are typically £50–£75 per fuel for early termination.
- Best suited to people who value certainty and are unlikely to move home in the term.
- Cap movements over 2 years are uncertain — fixing trades upside risk for predictability.

Choosing the best UK 2-year fixed energy deal
A clear, current overview to help you choose with confidence.
When a 24-month fix wins
If you expect the cap to rise materially in the next 4 quarters, a fix at or below the current cap protects you. It also smooths budgeting for households on tight monthly cashflow.
When the cap wins
If wholesale gas keeps softening and the cap continues to drift down, a tracker or the cap itself may beat a 24-month fix. There's no certainty either way — fix only if you can live with that risk.
What to compare like-for-like
Standing charge (p/day) + unit rate (p/kWh) for both fuels, paired with your annual kWh. Two deals with identical headline rates can differ in total cost when standing charges diverge.
Exit fees and price-lock terms
Most 24-month fixes have a per-fuel exit fee waived in your final 49 days. A handful of suppliers offer no-exit-fee fixes — useful if you may move home.

How to find the best 2-year fixed energy deal in May 2026
-
1. Find your kWh
Pull last year's gas and electricity kWh from your bill — or your supplier's online account.
-
2. Decide on dual-fuel or separate
Most homes choose dual-fuel for simplicity; running separate quotes is worth it if you want to maximise savings.
-
3. Compare like-for-like
Use the form below to see fixed deals priced for your postcode. Sort on estimated annual cost, not the headline unit rate.
-
4. Check exit fees
If you may move in the term, prioritise no-exit-fee tariffs or a 12-month fix instead.
-
5. Switch and submit readings
Your new supplier handles the change. Send opening meter readings to keep billing accurate.
Common pitfalls to avoid
The most frequent issues we see when households and businesses act on what looks like a good deal.
- Locking in a 24-month deal just before a cap reduction.
- Skipping the small print on standing charges — they drive ~£200/year of difference between deals.
- Forgetting to compare 12-month fixes too — sometimes the shorter term is cheaper per year.
- Fixing in your final 49 days of an existing contract and forgetting to cancel the auto-renewal.
Frequently asked questions
Are 2-year fixed energy deals worth it in May 2026?
They can be — if you find one at or below the prevailing cap and you want budget certainty for the next 24 months. They are less attractive if you expect the cap to keep falling.
Can I switch from a 2-year fix early?
Yes, with an exit fee. Typically £50–£75 per fuel during the fix; £0 in the final 49 days. A handful of suppliers offer no-exit-fee fixes.
Do all suppliers offer 24-month fixes?
Most major suppliers offer 12-month fixes, and several offer 18- and 24-month options too. Availability and pricing varies — a whole-of-market comparison will surface what's open to your postcode.
Will my standing charge be locked too?
Yes — fixed tariffs fix both the unit rate and the standing charge for the agreed term.
Do I need a smart meter?
Most fixed tariffs welcome but don't require smart meters. Some EV or time-of-use add-ons do require a SMETS2.
What happens at the end of a 2-year fix?
You'll be rolled onto your supplier's variable tariff if you don't switch. Suppliers must notify you 42–49 days before expiry. That's the time to compare again.
Is dual-fuel cheaper than separate gas and electricity fixes?
Sometimes. Dual-fuel discounts have shrunk since 2022 but a few suppliers still bundle. Always compare both pathways.
