Fast answer: compare fixed energy deals 2026
To compare fixed energy deals 2026, start by matching tariffs to your meter type and payment method (single‑rate, Economy 7, smart prepay, credit) and then compare the estimated annual cost for your postcode and usage. Check exit fees, contract length, and what happens when the fix ends before switching.
Key takeaway #1
A “good” fixed deal isn’t just the headline price—eligibility and meter fit (especially Economy 7 and prepay) often decide the real cost.
Key takeaway #2
A fix can add certainty, but may come with exit fees. If prices fall, leaving early can reduce (or remove) the benefit.
Key takeaway #3
Always compare using an estimated annual cost based on your usage, not just unit rates—standing charges and day/night splits matter.
Quick caveat: We don’t publish “best tariff” lists because prices are postcode‑specific and change frequently. Use the quote journey to see current options available to your home.
Compare fixed tariffs in 2026 (and get an accurate estimate)
Fixed deals can look similar until you account for how your home is billed. To get a like‑for‑like comparison, try to have these details ready:
1) Your postcode
UK tariffs vary by region (network costs differ). Postcode is essential for accurate pricing.
2) Meter type
Single‑rate, Economy 7 (day/night), smart meter, or prepayment can change which deals you can access.
3) Payment method
Direct Debit, receipt of bill, or prepay: prices and availability can differ by payment type.
4) Usage (kWh)
Annual kWh from bills is best. If you don’t have it, an estimate still helps rank deals sensibly.
If you’re renting: you can usually switch energy supplier if you pay the bills, but check your tenancy agreement and ensure you don’t leave debt on the meter/account.
What we’ll show you when you compare
- Estimated annual cost for your details (usage + postcode), so you can compare like‑for‑like.
- Contract length (e.g. 12/18/24 months) and key features.
- Exit fees and other important terms (where provided by suppliers).
- Options for electricity only, gas only or dual fuel (where available).

Fixed vs variable in 2026: what “fixed” really means
Fixed tariff
- Your unit rates and standing charges are typically set for the contract term (subject to the supplier’s terms).
- Often includes exit fees if you leave before the end date.
- Helps with budgeting, especially if you’re worried about future price rises.
Variable tariff
- Prices can change (for example, when a supplier updates rates).
- May have fewer penalties for leaving, but check the terms.
- Could benefit you if market prices fall, but gives less certainty month‑to‑month.
Important: The Ofgem price cap applies to certain variable tariffs (including many default tariffs) and limits what suppliers can charge per unit and standing charge in each region. It is not a cap on your total bill, and fixed tariffs can be above or below it. Read more at Ofgem: check if the price cap affects you.
Fixed deal comparison: what to look at (not just the headline)
When you compare fixed tariffs, you’ll typically see similar building blocks. This table shows what each element means and when it matters most.
| Deal detail | What it means | Why it matters in 2026 |
|---|---|---|
| Estimated annual cost | An estimate based on your usage, postcode, meter, and payment method. | Best single number for comparing. It accounts for standing charges and (if relevant) day/night splits. |
| Unit rate(s) | Price per kWh. Economy 7 has separate day and night rates. | High-usage homes are more sensitive to unit rates; Economy 7 homes must check the day/night balance. |
| Standing charge | Daily fixed cost to keep your home connected, regardless of usage. | Low-usage homes can find standing charges dominate bills; comparing by annual cost helps. |
| Exit fees | A charge if you leave a fixed contract early (often per fuel). | If you may move home, change meter type, or prefer flexibility, exit fees can be a key downside. |
| Contract length | How long the fixed rates last (e.g. 12–24 months). | Longer fixes increase price certainty but reduce your ability to respond if market prices fall. |
| End-of-fix outcome | What tariff you move to if you do nothing when the fix ends. | Many households roll onto a variable rate. Set a reminder a few weeks before your end date to review again. |
Decision checklist: who fixed deals tend to suit
A fixed deal may suit you if…
- You value predictability in monthly payments.
- You plan to stay in your home for the contract term.
- You’re happy with the trade‑off of less flexibility in return for certainty.
- You can meet eligibility (e.g. meter/payment type) for the best available options.
A fixed deal may not suit you if…
- You might move or need to change tariff/meter soon.
- You want the ability to switch quickly if prices drop.
- You’re on prepay and need maximum flexibility (some fixes exist, but terms vary).
- You’re not sure your Economy 7 day/night split will match the tariff assumptions.
Two realistic scenarios (with numbers)
These examples show how exit fees and contract length can change the outcome. They are illustrative—your quote will use your postcode and usage.
Scenario A: 12‑month fix vs staying flexible
Assumptions: dual fuel household; uses the same energy over the year; you’re comparing two deals where the fixed option’s estimated annual cost is £120 lower than the variable option at the time you switch.
If you stay the full term, the fixed deal could be cheaper by about £120 (before any changes in your usage). If you leave after 6 months and the tariff has a combined exit fee of £100, the remaining advantage could drop to around £(120 ÷ 2) − £100 = −£40 (i.e. it may not be worth it).
Scenario B: 24‑month fix with a mid‑term price drop
Assumptions: electricity‑only flat; your chosen 24‑month fix is competitive today; after 10 months, new fixed tariffs appear that are estimated to be £180/year cheaper for your details; your current fix has an exit fee of £75.
Switching early could save roughly £180 × (14/12) = £210 over the remaining 14 months, but after a £75 exit fee the net benefit might be about £135. This is why it’s worth checking exit fees and reviewing prices during the term.
Why we used “£/year” estimates: it avoids inventing unit rates and standing charges, which are postcode‑specific. Your results will show the actual figures available for your home.
Costs, exclusions and common pitfalls (UK)
These are the most common reasons a “good looking” fixed deal doesn’t work out as expected.
Exit fees (per fuel)
Many fixed deals charge to leave early. If you have both gas and electricity, fees can apply to each fuel. Always read the tariff information before committing.
Meter type mismatch
Economy 7 customers should check day/night rates and whether the quote assumes a specific split. Prepay customers should confirm the tariff is available for their meter setup.
Payment method differences
Direct Debit often prices differently to pay‑on‑receipt. When comparing, keep payment method consistent—otherwise you may compare two deals you wouldn’t actually use.
“End of fix” rollover
When a fix ends, you’ll typically move onto another tariff (often variable) unless you switch again. Put a calendar reminder for 3–6 weeks before your end date.
Moving home during the term
Some suppliers may let you transfer your tariff to a new address, others may not. If you expect to move in 2026, flexible terms could matter more than price.
Usage changes
If your household changes (working from home, EV charging, new heating), your annual kWh estimate may shift. Re‑quote using updated usage to avoid surprises.
If you’re in debt to your current supplier: you may still be able to switch, but there can be restrictions (especially for prepay). Citizens Advice explains your options: Citizens Advice: switching energy supplier.
FAQs about fixed energy deals in 2026
- Are fixed energy deals cheaper in 2026?
- Sometimes, but not always. Fixed deals can be above or below variable options depending on your postcode, meter type, payment method and when you compare. The safest approach is to compare by estimated annual cost for your home and check exit fees before you switch.
- What contract length is best for a fixed tariff in 2026?
- It depends on how long you want price certainty and how likely you are to move or switch again. Shorter fixes usually mean less commitment, while longer fixes can provide longer budgeting certainty but may reduce flexibility if prices fall.
- Do fixed energy tariffs have exit fees?
- Many do, but not all. Exit fees (also called termination fees) are typically charged if you leave before the end date, and may apply per fuel on dual fuel tariffs. Always check the tariff information and terms before you commit.
- Can I switch to a fixed deal if I have a prepayment meter?
- Often yes, but availability can be more limited and depends on your meter setup (including smart prepay) and your supplier’s eligibility rules. Compare using your postcode and select the correct meter and payment type to see what’s actually available.
- Does the Ofgem price cap apply to fixed deals in 2026?
- Not usually. The price cap limits unit rates and standing charges on certain variable tariffs (including many default tariffs), and the level varies by region and payment method. Fixed tariffs can be priced above or below the cap. See Ofgem’s overview: check if the energy price cap affects you.
- What information do I need to compare fixed tariffs accurately?
- Postcode, meter type (single‑rate or Economy 7, smart, prepay), payment method, and your annual usage in kWh (from recent bills if possible). If you don’t have kWh figures, an estimate still helps rank deals, but your results will be more accurate with real usage.
- How long does it take to switch to a fixed energy deal?
- Switching times can vary by supplier and circumstances (for example, meter type and whether there are any account issues), but many switches complete in a few working days. You’ll normally have a cooling‑off period, and your energy supply itself won’t be interrupted. For consumer help, see Citizens Advice guidance on switching.
Trust, transparency and how we assess fixed deals
Our methodology (plain English)
- Whole‑of‑market approach: we aim to show available tariffs from across the market for your inputs, rather than a hand‑picked shortlist.
- Like‑for‑like comparison: we prioritise estimated annual cost using your postcode, meter type and payment method, because unit rates alone can be misleading.
- Decision factors we highlight: contract length, exit fees (where provided), meter suitability (e.g. Economy 7), and what happens at the end of the fix.
Assumptions and limitations
- Prices change: tariffs can be withdrawn or repriced quickly. Always rely on the live quote results for your postcode.
- Usage is estimated: if you provide estimated kWh, your annual cost estimate may differ from your actual bill.
- Eligibility varies: some deals may require specific payment methods, credit checks, or meter types; terms are supplier‑set.
- No invented tariff claims: we do not publish supplier‑specific rates or “best deal” claims in this guide because they can become inaccurate and misleading.
