Estimates only. The price cap varies by region, payment method and meter type. Tariff availability and terms vary by supplier.
Fast answer: what is the energy price cap?
The Energy Price Cap is set by Ofgem and limits the maximum price per unit (kWh) and daily standing charge that suppliers can charge most households on standard variable tariffs (SVTs) and default tariffs. It is reviewed and reset every three months. It is not a cap on your total bill — use more energy and you pay more, even under the cap.
Current cap (July–September 2026, GB direct-debit average): electricity 26.11p/kWh with a 57.19p/day standing charge; gas 7.33p/kWh with a 29.04p/day standing charge. Ofgem confirmed these figures on 27 May 2026 and they took effect on 1 July 2026.
What it covers
Unit rates and standing charges on capped variable/default tariffs, for most domestic customers across Great Britain.
What it doesn’t do
It doesn’t cap your total bill, and it doesn’t automatically apply to fixed tariffs.
Why it matters
It is the baseline you judge every fixed deal against: a good fix in mid-2026 aims to beat these July cap unit rates.
The July 2026 (Q3) price cap rates in full
These are the headline cap unit rates and standing charges for the July to September 2026 period, on the GB average direct-debit basis Ofgem uses for its published figures. Your exact rates differ by region, payment method and meter type, but these are the benchmark every supplier’s SVT must sit at or below.
| Fuel | Unit rate (per kWh) | Standing charge (per day) |
|---|---|---|
| Electricity | 26.11p | 57.19p |
| Gas | 7.33p | 29.04p |
How this compares: the July cap electricity unit rate (26.11p) is slightly higher than the April–June 2026 cap, which sat at around 24.7p/kWh. Because the cap moves every quarter, the figure you saw earlier in 2026 will already be out of date — always check the period before you rely on a number.
What it means for a typical household bill
Ofgem also publishes an illustrative “typical annual bill” for a medium-use home that pays by direct debit. That figure is built from typical consumption values (TDCV): around 2,700 kWh of electricity and 11,500 kWh of gas per year. It is an illustration, not a maximum — your own annual cost depends on how much you actually use.
Worked through on the July rates above, a medium-use dual-fuel home is paying roughly: electricity 2,700 × 26.11p ≈ £705 plus 365 × 57.19p ≈ £209 standing; gas 11,500 × 7.33p ≈ £843 plus 365 × 29.04p ≈ £106 standing. That is around £1,860–£1,870 a year before VAT-inclusive rounding and regional variation. Treat it as a guide, not a quote.
How the price cap works (in plain English)
Ofgem sets the cap and reviews it on a fixed quarterly cycle — one level for January–March, April–June, July–September and October–December each year. Each review sets maximum allowed charges for different combinations of:
- Region (your local electricity distribution area)
- Payment method (e.g. direct debit, prepayment, standard credit)
- Meter type (single-rate, Economy 7 and other multi-rate, smart, prepayment)
Your supplier’s SVT must keep its unit rate(s) and standing charge at or below the cap level for your region and meter/payment type. When the cap changes — as it did on 1 July 2026 — suppliers update SVT rates automatically and notify you.
Important: the widely quoted “typical annual bill” you see in the news is an illustration based on typical use. Your home’s actual annual cost will differ from it.
Why does the cap change every quarter?
The cap mostly tracks wholesale gas and electricity costs, plus network and policy costs, over a recent reference window. When wholesale markets move, the next quarter’s cap moves with them. That is why the cap can rise in one quarter and fall in the next, and why the figure is dated to a specific three-month period.
Does the cap apply to fixed tariffs?
Usually no. Fixed tariffs have prices set in your contract for a period (e.g. 12 months). They can be above or below the capped SVT rates and may include exit fees if you leave early. In mid-2026 a number of suppliers are offering fixes priced around or slightly below the July cap unit rates — which is exactly when fixing can be worth a look.
Two realistic scenarios (with numbers)
These examples use the confirmed July 2026 cap rates to show how the cap shapes the rates you’re charged, not a guaranteed bill. Maths is simplified for clarity.
Scenario A: Medium-use dual fuel on SVT
Assumptions: direct debit; single-rate electricity; annual use 2,700 kWh electric + 11,500 kWh gas. July 2026 cap rates: electric 26.11p/kWh + 57.19p/day; gas 7.33p/kWh + 29.04p/day.
- Electric usage: 2,700 × £0.2611 ≈ £705
- Electric standing: 365 × £0.5719 ≈ £209
- Gas usage: 11,500 × £0.0733 ≈ £843
- Gas standing: 365 × £0.2904 ≈ £106
- Estimated total ≈ £1,863/year
Scenario B: Low-use flat, electricity only
Assumptions: single-rate electricity; annual use 1,600 kWh. July 2026 cap: 26.11p/kWh + 57.19p/day.
- Usage: 1,600 × £0.2611 ≈ £418
- Standing: 365 × £0.5719 ≈ £209
- Estimated total ≈ £627/year
In low-use homes, the standing charge is a large share of the bill — so comparing tariffs isn’t just about unit rates.
Figures use the GB average July 2026 cap. Real cap levels and supplier prices vary by region, payment method and meter type.
Should you fix, or stay on the capped variable? (and get a quote)
If you’re on a standard variable tariff, the July cap gives you consumer protection — but it doesn’t always mean it’s the best value. A fixed tariff can offer price certainty for 12–24 months, while a capped SVT keeps you flexible and tracks each quarterly review up or down. With several mid-2026 fixes priced near or just below the cap, it is worth comparing both for your postcode before deciding.
Quick guidance: when fixing tends to win
- You want predictability: a fix locks your unit rates for the term so the next cap change can’t raise them (check exit fees and end date).
- A fix is at or below the cap: if the per-kWh rate beats the July cap and the standing charge is comparable, fixing can save money and remove uncertainty.
- You’ve moved in recently: many homes default to the supplier’s SVT — worth checking and comparing.
- You have Economy 7 / multi-rate: compare like-for-like rates against your real day/night usage split.
- You’re on prepay: compare prepayment options; support and top-up methods can matter as much as price.
Caveat: if you’re in debt to your current supplier you may still be able to switch in some situations, but there can be restrictions — especially on prepayment meters. If in doubt, check with your supplier or Citizens Advice.

Tip: check your current tariff name on a recent bill or in your online account — especially whether it’s a fixed deal or a standard variable tariff — then compare it against today’s deals.
Capped variable vs fixed: side-by-side comparison
Use this to decide what to check before you switch. Individual tariffs differ, so always confirm the unit rate(s), standing charge, contract length and exit fees, and compare them against the July 2026 cap above.
| Feature | Price-capped SVT / default tariff | Fixed tariff | What to watch |
|---|---|---|---|
| Price certainty | Rates change at each quarterly cap update (next: Oct–Dec 2026) | Rates usually fixed for the contract term | When the fix ends you may move to SVT unless you choose another deal |
| Protection | Unit rates + standing charge limited by Ofgem cap | Not normally capped (contract prices apply) | Check if prices beat the July cap and whether you value certainty |
| Flexibility | Often no exit fees | May include exit fees for early leaving | If you may move home soon, check early termination charges |
| Meter types | Cap varies by meter/payment type (incl. prepay) | Availability can vary; not all suppliers offer all meter types | Economy 7: compare day/night rates and your usage split |
| Who it can suit | Those who want flexibility and a regulated ceiling on rates | Those who prefer budgeting certainty for a set term | Always compare total estimated cost, not just headline rates |
Decision checklist (quick)
- If you’re leaning towards a fixed tariff, check:
- Exit fees, contract length, what happens at the end of the fix, and whether the unit rate beats today’s July cap (26.11p elec / 7.33p gas).
- If you’re staying on a capped SVT, check:
- Your meter type and payment method, plus whether your standing charge is a big driver of costs (common in low-use homes).
- For any switch, confirm:
- Your current tariff name, whether you owe a balance, and whether you need like-for-like (e.g. Economy 7).
Who the price cap suits (and who it doesn’t)
Often suits: people who want flexibility, don’t want a long contract, or may move home soon.
May not suit: those who want stable monthly budgeting or who can access a fix priced below the July cap (after checking fees/terms).
There isn’t a single best option for every household — your region, meter, usage pattern and risk preference all matter.
Costs, exclusions and common pitfalls
A lot of confusion about the price cap comes from what it doesn’t do. These are the most common gotchas we see when households compare deals.
1) Thinking the cap limits your total bill
It doesn’t. The cap limits unit prices and standing charges — your total cost still depends on your kWh usage.
2) Using a stale cap figure
The cap resets every quarter. A rate quoted earlier in 2026 (e.g. the ~24.7p April cap) is out of date — the current figure is the July rate of 26.11p/kWh electricity.
3) Ignoring standing charges
Standing charges (57.19p/day elec, 29.04p/day gas under the July cap) can be a big share of the bill in low-use homes. Look at both the unit rate and the standing charge.
4) Not checking exit fees on fixes
Some fixed tariffs charge if you leave early. If you may move, or want freedom to switch again, read the tariff details carefully.
Does the cap apply to everyone?
It applies to most households on default/SVT tariffs in Great Britain. It won’t necessarily apply to bespoke deals, some specialist tariffs, or where a contract sets different prices (e.g. fixed deals). Northern Ireland has a separate regulatory regime.
Regional differences
The cap level varies by region. Two neighbours in different distribution regions can see different maximum standing charges and unit rates, even in the same quarter.
If you’re struggling to pay
If you’re worried about affording energy bills, you don’t have to handle it alone. Suppliers may offer payment plans and support, and there are independent organisations that can help you understand your options.

Energy price cap FAQs
What is the energy price cap for July 2026?
For July to September 2026 the GB average cap is 26.11p/kWh for electricity (57.19p/day standing charge) and 7.33p/kWh for gas (29.04p/day standing charge). Ofgem confirmed these figures on 27 May 2026 and they took effect on 1 July 2026. Your exact rates vary by region, payment method and meter type.
Is the price cap the same as the “typical annual bill” in the news?
No. The headline figure is an illustration based on typical usage (about 2,700 kWh electricity and 11,500 kWh gas a year). The actual cap is set as maximum unit rates and standing charges, which vary by region, payment method and meter type.
How often does the price cap change?
Every three months. Ofgem sets a cap for January–March, April–June, July–September and October–December. The current level is the July 2026 cap; the October–December 2026 cap has not been confirmed as of June 2026.
Should I fix my energy tariff in 2026, or stay on the cap?
It depends on your priorities. If a fixed deal’s unit rate is at or below the July cap (26.11p elec / 7.33p gas) with a comparable standing charge and acceptable exit terms, fixing can save money and remove quarterly uncertainty. If you value flexibility or may move home, the capped SVT may suit you better. Compare both for your postcode.
Can my fixed tariff be above the price cap?
Yes. The cap mainly applies to SVTs/default tariffs. Fixed deals can be priced above or below capped rates. If you’re considering a fix above the cap, weigh up price certainty versus potentially higher estimated costs.
Does the cap cover prepayment meters?
Yes. There are cap levels for prepayment customers too (including smart prepay). Your exact cap depends on region and meter/payment category, so comparing like-for-like is important.
Why are standing charges so high if there’s a cap?
The cap includes a maximum standing charge too — 57.19p/day for electricity and 29.04p/day for gas under the July 2026 cap — but that maximum can still be significant. Standing charges help cover fixed network and operating costs. Ofgem sets the cap using a defined methodology.
Do I need to contact my supplier when the cap changes?
Not usually. If you’re on an SVT, suppliers typically update rates automatically and notify you — as they did at the 1 July 2026 change. It’s still worth checking what you’re paying and comparing options if you want more certainty.
Need help working out your current rates?
You can usually find your unit rate(s) and standing charge on your bill under “Tariff information” or “About your tariff”. If you’re not sure what meter you have (single-rate vs Economy 7 vs prepay), we can help you interpret it when you request a quote.

How we assess the price cap (our method)
- We use the confirmed July 2026 (Q3) cap: 26.11p/kWh elec, 57.19p/day; 7.33p/kWh gas, 29.04p/day (GB direct-debit average).
- We explain the cap as limits on unit rates and standing charges, not a household bill limit.
- We highlight the main variables that change the cap: region, payment method and meter type.
- We use illustrative scenarios with stated assumptions to show how costs add up at the current rates.
- We focus on decision factors that affect real households: exit fees, end-of-fix reversion, multi-rate meters, and standing charge impact.
Limitations: the cap changes every quarter and varies by region. For your exact cap level, use Ofgem’s published tables and your supplier’s tariff information.
