Best two year fixed energy deal in the UK (what to look for now)
Two-year fixed tariffs can offer bill stability, but the “best” deal depends on your payment method, meter type, region and how much energy you use. Use this guide to compare like-for-like and see if a 24‑month fix suits you.

Fast answer: what’s the best two-year fixed energy deal right now?
There isn’t one single “best” two-year fixed tariff for everyone in the UK. The best deal for you is usually the two-year fix that offers the lowest estimated annual cost for your home after accounting for:
The numbers that matter
- Unit rates (p/kWh) for electricity and/or gas
- Standing charges (p/day) in your region
- Payment method (Direct Debit is often cheaper than pay on receipt / prepayment)
- Exit fees and contract terms (important with a 24‑month fix)
When a two-year fix tends to make sense
- You value price certainty for budgeting over the next two winters
- You’re happy staying put (or the exit fees are manageable)
- Your current tariff is a standard variable and the fix is competitively priced
- You can meet eligibility (e.g., smart meter requirements for some tariffs)
Important: “Fixed” usually means the unit rate and standing charge are fixed for the tariff term. Your bills can still go up or down if your usage changes (for example, colder weather or someone working from home).

How to choose the best two‑year fix (UK checklist)
1) Compare annual cost, not just p/kWh
A tariff with a lower unit rate can still cost more if the standing charge is high for your region. Always check the estimated yearly total for your usage.
2) Check exit fees (especially if you may move)
Two-year fixes often have exit fees. If you might move, ask whether you can take the tariff with you or what you’d pay to leave early.
3) Confirm your meter type & payment method
Deals vary for credit meters, smart meters, prepayment and Economy 7. Make sure the quote matches your setup.
4) Look for fair terms (not just price)
Consider customer service, billing options, greener electricity add-ons, and whether the supplier offers flexible Direct Debit adjustments if your usage changes.
Quick rule of thumb: If the two‑year fix is only marginally cheaper than a one‑year fix, think about whether the extra commitment and exit fees are worth it for you.
Two realistic examples (with numbers)
These are illustrative to show how a two‑year fix can work out. Your quote will differ.
Scenario A: dual fuel, typical usage, Direct Debit
- Assumptions: Electricity 2,700 kWh/year; Gas 11,500 kWh/year; single-rate electricity; GB average region; Direct Debit.
- Example two‑year fix: Elec 25.0p/kWh + 50p/day; Gas 6.4p/kWh + 30p/day; exit fees £100 per fuel.
- Estimated annual cost: Elec £928 + Gas £826 ≈ £1,754/year.
- What to check: If you switch again within 24 months, exit fees could add up (e.g., £200 total).
Scenario B: electric-only flat, low usage
- Assumptions: Electricity 1,800 kWh/year; no gas; credit meter; Direct Debit.
- Example two‑year fix: Elec 27.5p/kWh + 60p/day; exit fee £100.
- Estimated annual cost: Usage £495 + standing charge £219 ≈ £714/year.
- What to check: With lower usage, the standing charge can be a bigger share of your bill—so comparing standing charges matters more.
Calculations: unit rate × annual kWh + standing charge × 365. VAT is typically included in domestic tariffs; tariff T&Cs and regional rates vary.
What “two‑year fixed” means in the UK
- Fixed unit rates & standing charges
- The price per kWh and daily charge are set for the tariff term. Your monthly Direct Debit may still change if your supplier reviews your usage.
- Contract length: usually 24 months
- Leaving early may trigger exit fees (not always, but common).
- Eligibility varies
- Some tariffs require a smart meter, certain payment methods, or may exclude prepayment meters.
- You’re protected during switching
- If you’re switching supplier, the process is regulated and you shouldn’t be left without energy during a normal switch.
Two‑year fix vs other options (quick comparison)
Use this as a decision aid. Actual prices depend on your region, meter and payment method, and can change frequently.
| Option | Price stability | Best for | Watch outs |
|---|---|---|---|
| Two‑year fixed | High (rates fixed) | Budgeting and longer-term certainty | Exit fees; may miss cheaper deals if prices fall |
| One‑year fixed | Medium–high | Some stability with less commitment | May reprice sooner; still can have exit fees |
| Standard variable tariff (SVT) | Low (can change) | Flexibility; short-term stopgap | Rates can rise; you need to keep an eye on price changes |
| Tracker / variable deal (non‑SVT) | Low–medium | People comfortable with price movement | Can be volatile; check caps, formulas, and exit terms |
Who a two‑year fix suits
- You’re likely to stay in your home for 24 months
- You prefer predictable rates for budgeting
- You want to reduce the hassle of re-shopping yearly
- You’ve found a fix with sensible exit fees (or none)
Who it may not suit
- You may move, rent short-term, or expect life changes
- You’re on (or need) a prepayment meter and options are limited
- You want maximum flexibility to switch if prices drop
- You’re unsure about your usage (e.g., major home renovation, heat pump install)
Tip: If you’re comparing tariffs, ask for (or calculate) the annual cost using your own kWh figures from bills or your online account. That’s the most reliable way to judge “best”.
Costs, exclusions and common pitfalls (UK-specific)
Exit fees
Many two‑year fixed tariffs charge a fee if you leave early (often per fuel). If you might switch again within two years, include this in your decision.
Regional standing charges
Standing charges vary by region and network area. A deal that looks great in one postcode can be less competitive in another.
Meter type restrictions
Some tariffs require a smart meter, don’t support Economy 7/Economy 10, or aren’t available for prepayment customers. Always confirm eligibility.
Direct Debit changes
Even on a fixed tariff, suppliers may change your monthly Direct Debit if your account builds up debt/credit or your usage changes.
Dual fuel discounts (less common now)
Some suppliers price dual fuel attractively, but don’t assume it’s always cheaper. Sometimes separate suppliers for gas and electricity can work out better.
Introductory rates and end dates
Check when the fixed term starts and ends, and what tariff you move to afterwards if you don’t switch again.
Don’t compare on unit rate alone: For low users (or electric-only homes), a higher standing charge can wipe out a lower unit price. Use annual cost for your kWh where possible.
FAQs: two‑year fixed energy deals in the UK
Are two‑year fixed tariffs cheaper than standard variable tariffs?
Sometimes, but not always. A fixed tariff can be priced above or below a standard variable tariff (SVT). The reliable way to tell is to compare the estimated annual cost for your usage and region, and consider exit fees.
Will my bill stay the same on a fixed deal?
Your rates stay the same, but your bill can change if your energy use changes. If you pay by Direct Debit, the supplier may also adjust your monthly amount based on meter readings and account balance.
Do two‑year fixed deals have exit fees?
Many do, but it varies by supplier and tariff. Exit fees are often charged per fuel (gas and electricity separately). Always check the tariff information before switching.
Can I switch if I have a prepayment meter?
Yes, but your options may be more limited and prices can differ. Some fixed deals may not be available to prepayment customers, and eligibility can depend on the meter type and supplier policies.
What if I have Economy 7 or another multi-rate meter?
Make sure you compare tariffs that match your meter. Economy 7 has separate day/night rates, and the “best” deal depends on how much electricity you use overnight. A single-rate fix can be worse value if you rely on off-peak usage.
Is it harder to switch suppliers than it used to be?
For most households, switching is straightforward. Timelines can vary, and there may be extra steps if there’s a meter issue, debt on the meter, or an incorrect address or MPAN/MPRN record. You won’t be left without energy during a normal switch.
Do fixed deals protect me from the Ofgem price cap changing?
A fixed tariff keeps your agreed rates for the term, regardless of changes to the price cap level. The cap applies to standard variable tariffs and some default tariffs; fixed deals can be above or below that level.
What information do I need to find the best two‑year fix?
Ideally: your postcode, whether you have gas and electricity, your meter type (smart / credit / prepayment, and single or multi-rate), your payment method, and your annual usage in kWh (from a bill or online account).
If you’re unsure: You can still compare using postcode and household details. We’ll show estimated costs based on typical usage bands, then refine if you share kWh figures.

How we assess “best” two‑year fixed deals
Because availability and prices change frequently, this page doesn’t publish a single ranked list of “today’s best tariff”. Instead, we help you identify the best deal for your household using a consistent, transparent approach:
- Like-for-like eligibility: match tariffs to your meter type (credit/smart/prepayment, single vs multi-rate), fuel type (electric-only vs dual fuel), and payment method.
- Total cost focus: compare estimated annual cost using the tariff’s unit rates and standing charges for your region, applied to either your kWh or typical usage assumptions.
- Term & risk checks: factor in exit fees, end-of-fix outcomes, and constraints (e.g., smart meter requirements).
- User fit: weigh stability vs flexibility, especially if you may move home or expect major usage changes.
Limitations: Quotes can differ by supplier underwriting, availability, and how they treat discounts or add-ons. Always confirm the tariff information label and full terms before switching.
