What is the Ofgem energy price cap and who does it apply to?

The Ofgem energy price cap limits the maximum unit rates (p/kWh) and daily standing charges suppliers can charge customers on standard variable tariffs (SVTs) in Great Britain. It does not cap your total bill—your total cost depends on how much energy you use. The cap also affects default tariffs, including some ‘out of contract’ deals. It typically does not apply to fixed-rate tariffs, which have their own prices and terms.

Do I pay the exact price cap rates shown for my region?

Not always. The price cap sets a maximum level; suppliers can charge less. Your actual rates also depend on factors such as your payment method (e.g., Direct Debit vs. other methods), your meter type (credit vs. prepayment), and whether you’re on a fixed tariff rather than an SVT.

How can I find my energy region to check the correct capped rates?

Your energy ‘region’ usually corresponds to your electricity distribution area. You can often find it on a recent bill (sometimes shown as a ‘GSP group’ or regional code). If you’re unsure, use the regional information on this page and match it to your bill details, or check your supplier account information.

When do the April 2026 price cap rates take effect and how often do they change?

The April 2026 price cap rates apply for the cap period beginning in April 2026. Ofgem updates the cap on a regular schedule (typically every three months). That means the capped unit rates and standing charges can change at each new cap period.

Is a fixed tariff usually cheaper than the price cap?

A fixed tariff can be cheaper, similar, or more expensive than the price cap depending on wholesale prices and supplier offers at the time you switch. Fixes can provide certainty for budgeting, while SVTs track the cap changes. Comparing the total projected annual cost for your usage is the best way to judge value.

What’s the difference between unit rates and standing charges?

Unit rates are what you pay for each unit of energy you use (electricity in kWh and gas in kWh). Standing charges are daily fixed fees covering supply and network costs, paid regardless of usage. Both are included in the Ofgem price cap and can vary by region.

How do I reduce my bill if my regional cap rates are higher?

You may be able to lower costs by comparing fixed deals, reviewing your tariff type, paying by Direct Debit (if available and suitable), and reducing usage through efficiency measures (e.g., heating controls, insulation, LED lighting). Even small reductions in kWh used can have a meaningful impact when unit rates rise.

Ofgem energy price cap rates by region (April 2026)

Q: Why are price cap rates different by region?

Price cap rates vary by region mainly because network costs (the cost to transport electricity and gas) differ across regional distribution areas. These costs are built into unit rates and standing charges, so customers in different regions can see different capped prices even under the same Ofgem price cap period.

See how the April 2026 Ofgem price cap works, why regional rates differ, and how to compare deals against the cap for your meter and payment type.

Figures on this page are explained with examples and methodology. Your bill depends on usage, meter type, tariff, and exact rates in your area.

Fast answer: what the April 2026 price cap means (by region)

Ofgem’s energy price cap sets a maximum unit rate (p/kWh) and standing charge (p/day) that suppliers can charge for default tariffs (usually Standard Variable Tariffs) in each distribution region. That’s why the cap differs across the UK.

Important: The price cap is not a cap on your total bill. Your bill still depends on how much gas/electricity you use. The cap also doesn’t apply to most fixed tariffs.

Key takeaways

Region matters: standing charges and unit rates vary by electricity & gas network area.
Payment method matters: cap levels can differ for Direct Debit vs prepayment (including smart prepay).
Meter type matters: typical rates shown are for standard single-rate electricity; Economy 7 and other multi-rate tariffs are different.
Fixes can be above or below the cap: the cap limits default tariffs, not fixed deals.

Quick way to judge a deal

To compare any tariff to the cap for your region:

Check the standing charge (p/day) and unit rate (p/kWh) on your bill or online account.
Use your annual usage (kWh) if you have it (from your bill, smart app, or annual statement).
Estimate annual cost: (unit rate × kWh) + (standing charge × 365) (do this separately for gas and electricity).

If you don’t know your usage, you can still compare tariffs using your postcode and meter details—EnergyPlus can estimate costs using typical consumption values, but your actual cost will vary.

Compare tariffs against the April 2026 cap (your postcode)

Regional cap rates are driven by local network costs. If you tell us your postcode and contact details, we can show whole-of-market options and help you compare them to the cap for your area, meter type and payment method.

We’ll never claim a tariff will definitely be cheaper. We’ll show estimated costs using the information you provide, plus tariff rates and standing charges.

Why your region changes the cap

Ofgem sets cap levels using a cost model (wholesale, networks, policy costs, operating costs and an allowed margin). Network charges vary by region, so unit rates and standing charges under the cap vary too.

In practice, two neighbours on identical usage can see different bills if they’re in different electricity distribution regions (and gas networks), or if one household uses prepayment and the other pays by Direct Debit.

Two realistic examples (with numbers)

These examples show the math used to compare tariffs. They use illustrative rates so you can follow the method—your actual cap rates depend on your region and will be confirmed from Ofgem’s published tables.

Scenario A: typical dual fuel household

Payment method: Direct Debit (illustrative)
Electricity usage: 2,900 kWh/year
Gas usage: 12,000 kWh/year
Elec unit rate: 24.0p/kWh
Elec standing charge: 55p/day
Gas unit rate: 6.2p/kWh
Gas standing charge: 31p/day

Estimated annual electricity: (2,900×£0.24) + (365×£0.55) ˜ £897
Estimated annual gas: (12,000×£0.062) + (365×£0.31) ˜ £857
Total: ˜ £1,754/year

Scenario B: low electricity use + high standing charge impact

Home type: Flat (illustrative)
Electricity usage: 1,500 kWh/year
Elec unit rate: 23.0p/kWh
Elec standing charge: 65p/day

Estimated annual electricity: (1,500×£0.23) + (365×£0.65) ˜ £582/year

This is why comparing standing charges matters: at low usage, a higher standing charge can outweigh a slightly lower unit rate.

Use these calculations to compare any tariff to your regional cap rates. If you’re on Economy 7 (two unit rates) you’ll need to split usage into day/night.

Already have your rates?

Check your latest bill or online account for the electricity unit rate, electricity standing charge, and the same for gas. We use those exact figures when comparing.

What counts as a “region” for the price cap?

For electricity, the UK is split into regional distribution network areas (often called “GSP groups” in cap tables). For gas, regional variation is typically smaller, but can still be reflected through network charges.

Your cap rates can also vary depending on:

Payment method: Direct Debit, standard credit (cash/cheque), prepayment (including smart PAYG).
Meter type: single-rate, Economy 7/multi-rate, and (in some cases) profile class differences.
Fuel: electricity-only households will be more exposed to electricity standing charges and unit rates.

Northern Ireland has separate market arrangements and is not covered by Great Britain’s Ofgem price cap in the same way. If you’re in NI, tariff comparison still applies—but cap tables and regulators differ.

April 2026 cap: what to compare (not just the headline)

Ofgem’s headline “typical annual bill” is based on typical usage values. To make a meaningful comparison, focus on the rates that drive your bill.

What you’re comparing	Why it matters	Where to find it	Common mistake
Electricity unit rate (p/kWh)	Drives most of the cost if you use lots of electric heating or have high usage.	Bill/online account; tariff information label.	Comparing a single rate to an Economy 7 tariff without splitting day/night usage.
Electricity standing charge (p/day)	Can dominate costs for low-usage homes (small flats, vacant properties).	Bill; tariff info label.	Only checking unit rate and ignoring standing charge differences by region.
Gas unit rate (p/kWh)	Big impact in winter; most homes use far more gas kWh than electricity kWh.	Bill; tariff info label.	Comparing monthly direct debit amounts instead of rates and usage.
Gas standing charge (p/day)	Smaller than electricity for many households, but still adds up over a year.	Bill; tariff info label.	Assuming zero cost in summer: standing charges still apply.
Exit fees (fixed tariffs)	Can offset any short-term saving if you leave early when cap rates change.	Tariff terms; supplier tariff page.	Switching away without checking whether fees apply to each fuel.

Decision checklist: who this suits

You’re on a standard variable tariff and want to see if a fixed deal is competitive.
You can find your kWh usage (or you’re happy with an estimate).
You’re open to checking standing charges, not just unit rates.
You want clarity on exit fees and tariff end dates before switching.

Who it may not suit (or needs extra care)

You have Economy 7 and don’t know day/night split (we can help, but it’s not a 1:1 comparison).
You’re in debt repayment arrangements—switching may be restricted for some setups.
You rely on a prepayment meter and need to confirm compatibility with a new supplier.
Your home is all-electric: small rate differences can have bigger impacts, so accuracy matters.

If you want the official “cap rates by region” tables for April 2026, we recommend checking Ofgem’s published price cap annexes (see Sources below). They list the exact standing charges and unit rates by region and payment type.

Costs, exclusions and common pitfalls (April 2026 cap)

The cap is widely reported, but the details matter. Here are the most common issues that cause confusion when comparing tariffs.

1) “The cap is my bill”

It’s a cap on rates. If you use more than the typical consumption, your bill can be higher; if you use less, it can be lower.

2) Comparing monthly Direct Debit amounts

Monthly payments can include catch-up, credit building, or repayment plans. Compare unit rates, standing charges, and kWh usage instead.

3) Economy 7 and multi-rate meters

You may see separate day/night unit rates. A “cheaper” night rate only helps if a meaningful share of your usage is overnight.

4) Exit fees and tariff end dates

Fixed deals can have exit fees per fuel. If you switch when the cap changes, fees can reduce the benefit.

5) Standing charges dominate at low usage

If your home is vacant, small, or you’re away often, standing charges can be a large part of the annual cost—region differences really show up here.

6) VAT and bill presentation

Household energy is typically shown inclusive of VAT. Always check whether rates are displayed inc. VAT when comparing sources.

If you’re struggling to pay, switching isn’t always the best first step. You may be able to access support like repayment plans, emergency credit (prepay), or help via trusted advice services. See Citizens Advice in the Sources section.

FAQs: Ofgem price cap rates by region (April 2026)

Does the price cap apply to fixed tariffs?

No. The cap limits what suppliers can charge on default tariffs (often SVT). Fixed deals can be priced above or below the cap. Always compare total estimated cost and check exit fees.

Why are price cap rates different by region?

A big driver is network costs (moving electricity/gas around safely). Those costs vary between distribution areas, which is reflected in the cap’s standing charges and unit rates.

How do I find my price cap region?

The easiest way is by postcode. Suppliers and comparison services map your address to your electricity distribution region (and relevant gas network). The official Ofgem annexes then show the rates for that region.

Are standing charges capped too?

Yes. The cap sets a maximum standing charge as well as a maximum unit rate. Standing charges can still be high, especially for electricity, and they vary by region and payment method.

Is the cap the same for prepayment meters?

Not always. Ofgem publishes separate cap levels for different payment methods, including prepayment (and smart prepayment). If you’re on prepay, compare tariffs that specifically support your meter type.

Will my supplier automatically put me on the cap?

If you’re on a supplier’s default tariff, the rates you pay should not exceed the cap for your region and payment type. If you’re on a fixed tariff, your rates are set by your contract, not the cap.

How often does the price cap change?

The cap is updated periodically (typically quarterly). That’s why a fixed deal can look good at one point but become less competitive later—especially if there are exit fees.

What if I rent—can I still switch?

Most tenants can switch supplier if they pay the bills, but check your tenancy agreement for any restrictions and confirm you’re not switching a landlord-supplied arrangement. You should not be charged for a normal supplier switch.

What should I do if I can’t afford my energy bills?

Contact your supplier as early as possible—there may be payment plans or support options. For independent help, Citizens Advice has step-by-step guidance for England, Wales and Scotland.

How we assess “price cap rates by region”

This guide focuses on the parts of the cap that change by region and affect real bills: electricity and gas unit rates and standing charges, split by payment method and (where relevant) meter type.

When we show worked examples, we:

Use the standard bill formula: (unit rate × annual kWh) + (standing charge × 365) for each fuel.
State assumptions (usage and sample rates) so you can replicate the calculation.
Explain where results may differ (Economy 7, seasonal use patterns, debt repayment plans, and VAT display differences).

Limitations: This page explains how to interpret April 2026 cap rates by region and how to compare tariffs. It does not replace the official Ofgem annex tables, and it cannot guarantee what you will pay because usage varies.
