Best fixed-rate energy tariff UK — how to beat the 1 July 2026 cap rise
The Ofgem price cap rose to £1,862/yr on 1 July 2026 (+£221 / +13.5%). A fixed-rate tariff locks your unit rates and standing charges for the whole term, so a rising cap can’t touch you. This guide explains how to choose the right fix — term, exit fees and unit rates — what “% below the cap” really means, and who should (and shouldn’t) fix right now.
- Why fixing now beats the rising £1,862 cap — the plain-English math
- How to compare fixes properly: term length, exit fees, unit rates vs cap
- What “up to ~10% below the cap” means — and why your number varies by region
- A clear who-should-fix / who-shouldn’t checklist, plus an 8-question FAQ
Quick answer: is fixing worth it now the July 2026 cap has risen?
For most households still on a default Standard Variable tariff, yes. From 1 July 2026 the price cap rose to £1,862/yr (typical use), an extra £221 a year (about £18 a month). The cheapest fixed deals currently sit up to roughly 10% below that new cap, and a fix freezes your rates for the whole term — so if the cap rises again at the next review (1 October 2026), you’re shielded.
The exact saving depends on your region and usage, so the only way to see your number is to compare live prices for your postcode. Enter your details in the form on this page and we’ll show the fixes available at your address, ranked by annual cost, with exit fees and any smart-meter requirement labelled.
Why fixing now beats the rising £1,862 cap
The Ofgem cap is not a maximum bill — it caps the unit rate and standing charge on a Standard Variable tariff, and it moves every three months. From 1 July 2026 it rose to £1,862/yr for a typical dual-fuel direct-debit home, up £221 (+13.5%) on the spring level of £1,641. Almost all of that increase is on the gas side: gas unit rates climb about 24% while electricity rises only around 5%.
A fixed-rate tariff does the opposite of the cap — it locks your unit rates and standing charges for the agreed term (typically 12, 18 or 24 months). Once you fix, the July rise can’t reach you, and neither can the next cap change at the 1 October 2026 review. That certainty is the whole point: you trade the chance of the cap falling for protection against it rising.
Around 40% of accounts are already on a fix and will see no change in July. The households exposed to the rise are those still sitting on a default Standard Variable rate. If that’s you, comparing a fix now is the single clearest way to limit the increase. Tip: take a meter reading on 30 June so your supplier bills usage up to that date at the cheaper current cap.

The July 2026 cap math — what a fix can save
The table below shows what a typical-usage household (Ofgem TDCV: 2,700 kWh electricity + 11,500 kWh gas, dual fuel, direct debit) would pay across a year at different positions relative to the new cap. The “below cap” figures are illustrative — the best market fixes have recently run up to around 10% under the cap, but the exact discount varies by region and supplier. Use the form above to see the real numbers for your postcode.
| Your position | Typical annual cost | Vs new £1,862 cap | Roughly per month |
|---|---|---|---|
| Standard Variable (capped) from 1 July | £1,862 | — (this is the cap) | ≈ £155 |
| Fix at ~5% below cap | ≈ £1,769 | save ≈ £93/yr | ≈ £147 |
| Fix at ~10% below cap | ≈ £1,676 | save ≈ £186/yr | ≈ £140 |
| Old spring cap (Apr–Jun, for reference) | £1,641 | £221 below the new cap | ≈ £137 |
Figures use the Ofgem typical-use benchmark and are rounded for illustration; your bill depends on actual consumption, region and payment method. Prepayment customers face a typical cap of £1,812/yr from 1 July and on-receipt (standard credit) £2,005/yr. Live fixed prices for your address appear when you run the comparison above.
How to choose a fixed-rate tariff — the three things that matter
1. Term length
A 12-month fix balances price and flexibility — you reprice in a year and can capture any later fall. An 18-month fix is the popular middle ground, covering two winters and the volatile spring. A 24-month fix is set-and-forget certainty, usually at a slightly higher rate. Pick the term that matches how long you want the certainty, not just the headline price.
2. Exit fees
Most fixes charge an exit fee per fuel (commonly £25–£50 each) if you leave early; some best-buys charge nothing. Exit fees only bite if you switch during the term — and Ofgem rules waive them in the final 49 days. If you expect to move home or re-shop soon, favour a low- or zero-exit-fee deal.
3. Unit rates, not just the headline
The annual figure assumes typical use. If you use a lot of gas, compare the p/kWh gas rate; if you’re heavy on electricity (EV, heat pump), weight the elec rate and standing charge. Two tariffs with the same “typical” cost can differ by £100+ for your actual usage — which is why the comparison form asks for your consumption.
For reference, the July 2026 capped Standard Variable unit rates are: electricity 26.11p/kWh + 57.19p/day standing charge; gas 7.33p/kWh + 29.04p/day. A good fix should beat the unit rates that matter most for your home — the form ranks deals on your real usage, not just the typical benchmark.
What “up to ~10% below the cap” actually means
When a deal is described as “X% below the cap”, the comparison is against the typical-use Standard Variable cap (£1,862/yr from 1 July). A fix at 10% below the cap implies a typical annual cost of roughly £1,676. But the cap itself varies by region (standing charges differ), and your usage may be higher or lower than typical — so your personal “% below” can be bigger or smaller than the headline.
Why your number varies by region
Ofgem sets regional standing-charge differentials, so the same fixed tariff can cost ±£25/yr or more at the typical benchmark depending on where you live. Suppliers also offer different rates in different areas. That’s why we don’t publish a single fixed price here — the only accurate figure is the live one for your postcode, which appears when you run the comparison form on this page.
Who should fix — and who probably shouldn’t
Fixing makes most sense if you…
- Are on a default Standard Variable tariff and exposed to the 1 July rise.
- Value budget certainty and want to know your rates won’t move for a year or more.
- Can find a fix priced below the £1,862 cap for your region (most can right now).
- Want protection in case the 1 October 2026 review pushes the cap higher again.
Hold off / take care if you…
- Are already on a competitive fix — your rates are protected; check the exit fee before switching.
- Are near the end of a fixed term — re-compare in the final 49 days when exit fees are waived.
- Strongly expect wholesale prices to fall sharply later — a shorter 12-month fix keeps you flexible.
- Are on a special tariff (warm home discount, EV/time-of-use) — check the fix doesn’t cost you those perks.
Looking further ahead: Cornwall Insight forecasts the cap at around £1,899/yr for the October 2026 quarter (current-TDCV basis) — a forecast, not a confirmed figure. Locking a fix now removes that uncertainty for the length of your term.
How to switch to a fixed-rate tariff — four steps
- Take a fresh gas and electricity meter reading today — ideally on or before 30 June — so your changeover uses an actual reading, not an estimate.
- Run the comparison form above with your postcode and rough usage. The live fixes available at your address appear with annual cost, exit fee and any smart-meter requirement clearly labelled.
- Pick a fix and apply online — typically 5–10 minutes including direct-debit setup. There’s no engineer visit and no break in supply.
- Your switch completes within 5 working days under the Faster Switch Guarantee. Your old supplier sends a final bill within six weeks; your fixed rates apply from day one of the new contract.
Frequently asked questions — best fixed-rate energy tariff
Should I fix my energy now the 1 July 2026 cap rise has landed?
If you’re on a default Standard Variable tariff, fixing now usually makes sense. The cap rose to £1,862/yr (+£221, about £18 a month) and the best fixes currently sit up to around 10% below it. A fix also shields you from the next cap change at the 1 October 2026 review. Enter your postcode in the form on this page to see the deals available for your address.
Does the July 2026 cap rise affect fixed-rate deals?
No. The price cap only applies to Standard Variable tariffs. If you’re on a fix, your unit rates and standing charges are locked for the whole term — the July rise (and any later cap change) doesn’t touch you. Roughly 40% of accounts are already on a fix and unaffected.
How much more will the cap cost from 1 July 2026?
For a typical dual-fuel direct-debit home the cap rose from £1,641 to £1,862/yr — an extra £221 a year, or about £18 a month. Almost all of the increase is on gas (unit rates up about 24%); electricity rises only around 5%.
What does “X% below the cap” mean on a fixed tariff?
It compares the fix to the typical-use Standard Variable cap of £1,862/yr. A fix at 10% below implies a typical annual cost of roughly £1,676. Because the cap varies by region and your usage may differ from typical, your personal “% below” can be higher or lower — the comparison form shows your real figure.
Is a 12, 18 or 24-month fix best?
It depends on how long you want certainty. A 12-month fix keeps you flexible to capture any later fall; an 18-month fix is the popular middle ground covering two winters; a 24-month fix is maximum set-and-forget certainty, usually at a slightly higher rate. Compare the actual prices for each term using the form on this page.
What are exit fees and when do they apply?
An exit fee is a charge (commonly £25–£50 per fuel) for leaving a fix early; some best-buys charge nothing. Fees only apply if you switch supplier during the term, and Ofgem rules waive them in the final 49 days. Switching to your own supplier’s new tariff at the end of the term is always free.
Why is gas rising so much more than electricity?
The July 2026 increase is driven mainly by higher wholesale gas costs, so gas unit rates climb about 24% while electricity rises only around 5%. Homes that use a lot of gas for heating therefore feel the rise most — a fix locks both fuels at today’s rates.
Will energy prices fall later in 2026?
No one can promise that. Cornwall Insight forecasts the cap at around £1,899/yr for the October 2026 quarter (a current-TDCV forecast, not confirmed), with the next official review on 1 October 2026. Fixing removes that uncertainty for the length of your term; a shorter 12-month fix keeps you flexible if you expect a later fall.
