Prices and availability vary by region, meter type and payment method. Any figures shown are examples based on stated assumptions and should be treated as estimates.
Fast answer: what’s the best two year fixed energy deal?
There isn’t one “best” 2-year fixed tariff for everyone in the UK — the best option is the lowest total estimated annual cost for your postcode, meter type and payment method, with exit fees and terms you’re comfortable with over a 24‑month period.
Quick rule of thumb: a 2-year fix can suit you if you want price certainty and you’re unlikely to move or switch soon. If you expect to move, change usage a lot, or want flexibility, a shorter fix or a variable tariff may be safer.
Key takeaways (UK-specific)
Look beyond unit rates.
Standing charges vary by region and can change which tariff is “best” for low or high usage households.
Exit fees matter more on 2-year fixes.
Check fees per fuel and what happens if you move home or change tariff mid‑term.
Eligibility can exclude you.
Some deals are limited by meter type (e.g., Economy 7), payment method, or credit checks.
Compare two-year fixed tariffs for your home
We’ll use your postcode and contact details to help you compare available options across the market, including 2‑year fixed tariffs where eligible. You’ll see estimates based on your details — not generic averages.
- Whole-of-market comparison (where available)
- Works for renters and homeowners (domestic supply only)
- Tailored by region, meter type and payment method
Tip: Have a recent bill handy. If you can provide annual kWh for gas and electricity (or monthly spend), the estimates are more accurate.
How to choose the right 2‑year fix (in 5 checks)
- Confirm your meter type: single-rate, Economy 7, smart, or prepayment. Some tariffs won’t be available on certain meters.
- Compare total annual cost (not just rates): standing charge + unit rate × your usage, for both fuels if dual fuel.
- Check exit fees: per fuel, and whether they apply if you move home or switch supplier.
- Check payment method: Direct Debit tariffs often price differently to pay-on-receipt-of-bill or prepayment.
- Read the tariff end rules: what happens at the end of the fix, and whether you’ll be rolled onto a variable tariff if you do nothing.

2-year fixed vs other tariff types (UK comparison)
If you’re searching for the “best two year fixed energy deal”, it helps to compare the trade-offs rather than only the headline price. Use this table to decide what to shortlist.
| Tariff type | Best for | Watch-outs | What to compare |
|---|---|---|---|
| 2-year fixed | People who value stability and expect to stay put | Exit fees; moving home; being locked in if market falls | Total annual cost, exit fees per fuel, end-of-fix terms |
| 1-year (or shorter) fixed | Some price certainty with less commitment | May still have exit fees; may not be cheapest per kWh | Exit fees, standing charges, renewal options |
| Standard variable | Maximum flexibility; short-term stopgap | Prices can change; usually not the best long-term value | Current rates vs alternatives; notice period for changes |
| Tracker (where available) | Those comfortable with movement, wanting transparency | Rates can rise quickly; may have caps/limits and rules | How it tracks, caps, exit fees, volatility risk |
Decision checklist: who a 2-year fix suits (and who it doesn’t)
A 2-year fixed may suit you if…
- You expect to stay in the property for at least 12–24 months
- You want predictable budgeting and fewer price shocks
- You’re happy with the tariff rules even if cheaper deals appear later
- You can meet eligibility (meter type, payment method, credit requirements)
Consider alternatives if…
- You may move, sublet, or change supplier soon (exit fees risk)
- You’re on a prepayment meter and limited in available tariffs
- Your usage is likely to change a lot (e.g., new baby, EV charger, home working)
- You prefer flexibility to switch if prices drop
Two realistic cost scenarios (examples with assumptions)
Scenario A: medium-use dual fuel household (Direct Debit)
Assumptions (example only): England/Scotland/Wales region, single-rate electricity meter, monthly Direct Debit; annual use 2,900 kWh electricity and 12,000 kWh gas.
| Item | 2-year fix (example) | 1-year fix (example) |
|---|---|---|
| Estimated annual cost | £1,620 | £1,660 |
| Exit fees | £150 gas + £150 electricity | £75 gas + £75 electricity |
| Why the “best” differs | Slightly lower estimate, but higher commitment | More flexibility, smaller exit-fee risk |
These example totals are illustrative. Real quotes depend on your exact region and supplier pricing at the time you apply.
Scenario B: low-use electric-only flat (pay on receipt)
Assumptions (example only): electric-only property, single-rate meter; annual use 1,800 kWh electricity; paying on receipt of bill (not Direct Debit).
Why this matters: for low use, a higher standing charge can outweigh a slightly lower unit rate. Payment method can also change prices.
- Example 2-year fix estimate
- £740/year (includes standing charge)
- Example variable estimate
- £720/year (but can change)
- Exit fee risk
- If you move after 8 months, you may pay an exit fee that wipes out small differences
If you rent and might move, prioritise low/no exit fees and check moving-home rules before fixing for 2 years.
Costs, exclusions and common pitfalls (2-year fixed deals)
Two-year fixes can be a good fit, but the “best” deal on paper can disappoint if the fine print doesn’t match your situation. These are the issues we see most often for UK households.
1) Exit fees (per fuel)
Exit fees are often charged for gas and electricity separately. On dual fuel, leaving early can mean two fees. Always check the amount and when it applies.
2) Standing charges vary by region
You can’t reliably compare tariffs without your postcode. Regional standing charges and unit rates can change the ranking of “best” deals.
3) Meter type limitations
Economy 7 / multi-rate meters and some prepayment setups can have fewer fixed options. If you have a smart meter, check whether smart functionality is supported after switching.
4) Payment method pricing
Many tariffs are priced for monthly Direct Debit. If you pay on receipt of bill or use prepayment, the same named tariff may not be available or may cost more.
5) Moving home during the fix
Some suppliers let you “transfer” a tariff to a new address, but it’s not guaranteed (availability and meter compatibility matter). Ask about moving rules before you commit.
6) End-of-fix rollover
At the end of a fixed term, suppliers usually move you onto a variable tariff if you don’t choose a new deal. Set a reminder for 45–60 days before the end date.
Important: The Ofgem price cap applies to standard variable tariffs (and some default tariffs), not to fixed deals. A fixed deal can be above or below what you’d pay on a capped variable tariff.
FAQs: two-year fixed energy deals (UK)
Are two-year fixed tariffs cheaper than variable tariffs?
Sometimes, but not always. A 2-year fix can be cheaper or more expensive than a standard variable tariff. Compare the estimated annual cost for your usage and postcode, and consider the value of price certainty versus flexibility.
Will a two-year fix protect me from price rises?
A fixed tariff usually keeps the unit rates and standing charges the same for the fixed period, but always check the contract terms. It won’t necessarily protect you from changes unrelated to the tariff terms (for example, if you fall behind and move to a different payment arrangement).
Do two-year fixed deals have exit fees?
Often, yes. Exit fees can apply if you leave before the end date, and they may be charged per fuel (gas and electricity). Always check the amount, the exceptions, and whether the fee changes nearer the end of the contract.
Can I get a two-year fix with a prepayment meter?
Possibly, but choice can be more limited and eligibility depends on the supplier and meter setup (traditional vs smart prepay). If you’re considering moving from prepayment to credit, check requirements and whether a credit check is needed.
What if I have Economy 7 (or another multi-rate meter)?
You’ll need a tariff that supports multi-rate pricing. The “best” deal depends heavily on how much electricity you use overnight versus daytime. If your night use is low, a single-rate tariff may be better — but only if it’s compatible with your meter or if you’re able to change it.
Will switching disrupt my supply?
Switching supplier should not interrupt your gas or electricity supply. Your meters stay in place in most cases. There may be administrative steps (e.g., meter readings), and timelines can vary.
Is dual fuel always cheaper than separate suppliers?
Not necessarily. Some suppliers offer dual-fuel discounts, but the best value can still be from separate suppliers depending on rates and standing charges. Compare both ways if you’re flexible.
What details do I need to compare accurately?
Your postcode, meter type (single-rate/Economy 7/prepayment/smart), payment method, and ideally annual usage in kWh for gas and electricity. If you don’t know kWh, a recent bill is usually enough to estimate.

How we assess “best two-year fixed” deals
Our editorial approach is to prioritise user outcomes over headlines. “Best” means the most suitable mix of cost and terms for a typical UK household — and we encourage you to compare using your own details.
- Primary measure: estimated annual cost (unit rates + standing charges) using the customer’s postcode and usage assumptions.
- Term risk: exit fees (per fuel), moving-home rules, and contract conditions.
- Eligibility: meter type (single-rate/Economy 7/smart/prepayment), payment method (Direct Debit vs other), and any stated credit requirements.
- Service practicality: how clearly the tariff terms are presented and what happens at end of fix.
Limitations: Energy pricing can change frequently and not all tariffs are available to all customers. The example scenarios on this page use simplified assumptions to illustrate decision-making, not to predict your bill.
