Price cap unit rates by region (April 2026): what you’ll pay
A UK-focused guide to how Ofgem’s price cap works, why unit rates can differ by region, and how to estimate your bill using your meter type and payment method.
- See what “regional unit rates” means (and what it doesn’t)
- Work out your estimated cost using unit rates + standing charges
- Compare against fixed deals safely (exit fees, meter rules, eligibility)
Figures vary by region, payment method and meter type. This page explains the method and what to check before switching.
Fast answer: what are “price cap unit rates by region” for April 2026?
Ofgem’s energy price cap (for customers on standard variable and most default tariffs) limits the maximum suppliers can charge for unit rates (p/kWh) and standing charges (p/day). Those cap levels can differ by region because some network costs vary depending on where you live.
Important: April 2026 cap figures are set by Ofgem and published close to the period. This guide explains how to find the correct regional unit rates and how to use them to estimate your costs, plus what to check before switching.
Key takeaways
- Region matters: your cap level is based on your electricity distribution region (and gas region), not your council area.
- Payment method matters: direct debit vs prepayment can have different cap levels.
- Meter type matters: single-rate vs Economy 7 (two-rate) electricity has different unit rates.
- Bills aren’t capped: your total bill changes with usage. The cap is on rates, not the total you’ll pay.
What to do next
- Identify your payment method and meter type.
- Find your region code on a bill (MPAN for electricity; or ask your supplier).
- Estimate your monthly cost using: unit rate × usage + standing charge.
- Compare against fixed deals with the same assumptions (usage, meter, region).
Estimate your cost using April 2026 capped rates (step-by-step)
To estimate what you’d pay on a price-capped tariff, you need four inputs: your region, payment method, meter type, and annual usage (kWh).
1) Find your region (electricity) and area (gas)
Your electricity “region” is your distribution network area. Often you can find it on your bill via your MPAN (the 2-digit DNO code), or by asking your supplier. Gas uses a separate “Local Distribution Zone” in Ofgem tables.
2) Confirm payment method and meter type
Typical categories are Direct Debit, standard credit (pay on receipt of bill), and prepayment (including smart prepay). Electricity may be single-rate or two-rate (Economy 7).
3) Use the correct unit rate and standing charge
Ofgem publishes the cap as maximum unit rates (p/kWh) and maximum standing charges (p/day), by region and payment method. Suppliers can set rates below the cap.
4) Do the maths (electricity and gas separately)
Estimated annual cost ˜ (unit rate × annual kWh) + (standing charge × 365). Divide by 12 for a rough monthly estimate. For Economy 7, you’ll need day and night kWh split.
Why this page doesn’t list April 2026 numbers: cap levels are published by Ofgem close to the quarter and can change. Listing predictions risks being wrong and unhelpful. Instead, we show you exactly how to locate the official table and how to use it to compare deals accurately.
Where to get the official April 2026 regional unit rates
When Ofgem publishes the cap for April–June 2026, look for the document/table that lists:
- Electricity unit rates and standing charges by region
- Gas unit rates and standing charges by region/LDZ
- Separate values for direct debit, standard credit, and prepayment

Compare whole-of-market deals for your home
If you share your postcode and a few details, we’ll show tariffs available for your region, meter and payment preference. No promises of savings—just transparent comparisons.
Two realistic examples (with numbers)
These scenarios use example rates to show the calculation. Replace with the official April 2026 regional unit rates and standing charges from Ofgem (and your supplier’s rates if you’re on a tariff below the cap).
Scenario A: 1-bed flat, electricity only (single-rate)
If your usage rises (electric heating, tumble dryer), your bill rises—even if the cap stays the same.
Scenario B: 3-bed semi, dual fuel (gas + electricity)
Your real bill depends on the April 2026 regional cap levels (or your supplier’s tariff if lower), and your actual kWh usage.
Compare your options: capped tariff vs fixed deal (April 2026)
Use the table below to decide what to do once April 2026 cap rates are published for your region. The best choice depends on your risk preference, contract terms, and whether you can access a competitive fixed tariff.
| Option | How prices change | What to watch | Who it can suit |
|---|---|---|---|
| Price-capped standard variable (SVT) | Rates can change each cap period (quarterly), up to Ofgem’s cap for your region/meter/payment type. | Budgeting uncertainty; standing charges can be a large share if usage is low. | People who want flexibility and no long-term contract (often no exit fees). |
| Fixed tariff (e.g., 12 months) | Unit rates/standing charges fixed for the term (unless contract allows changes). | Exit fees; eligibility/credit checks; check if it’s single fuel vs dual fuel; Economy 7 suitability. | People prioritising predictability and willing to accept exit fees to lock rates. |
| Tracker / variable deal (not SVT) | Rates follow a formula (e.g., wholesale index) and can move frequently. | Price volatility; read terms on how often rates change and any caps/floors. | People comfortable with changing prices and who understand the risk. |
Decision checklist (quick)
- Do you know your meter type (single-rate vs Economy 7)?
- Are you direct debit, credit, or prepay?
- Do you have your annual kWh usage for gas and electricity?
- Can you tolerate a bill change next quarter if cap rates rise/fall?
- Would an exit fee be a problem if you need to move or switch again?
Who switching tends to suit (and who it doesn’t)
Often suits: households with stable address plans (12+ months), clear usage history, and a deal where the all-in estimate (unit rate + standing charge) looks competitive for their region.
May not suit: renters likely to move soon, anyone with uncertain affordability (exit fees), or Economy 7 customers whose usage is mostly daytime (fixed single-rate deals can be worse).
Costs, exclusions and common pitfalls (UK-specific)
Most confusion comes from mixing up cap rates with bill totals, or comparing tariffs without matching the same region/meter/payment method.
1) The cap doesn’t cap your bill
If you use more kWh (cold winter, working from home, electric heating), you pay more—even if unit rates are capped.
2) Standing charges can dominate low-usage homes
For small flats or second homes, standing charges can be a big part of the bill. Comparing unit rates alone can mislead.
3) Economy 7: check your split
Two-rate tariffs can be great if a meaningful share of usage is at night. If most usage is daytime, it can cost more.
4) Prepayment differences
Prepayment (including smart prepay) has its own cap values. Make sure you’re comparing like-for-like—especially if you’re moving to/from prepay.
5) Exit fees and moving home
Many fixed deals charge exit fees per fuel. If you might move, check whether you can transfer the tariff to your new address or leave without penalty.
6) Eligibility and tariffs you can’t access
Some tariffs are limited by meter type, payment method, credit checks, or supplier policies. Always read the tariff information label and key terms.
Tip: When comparing, always use the same annual usage figures (kWh), and include both unit rates and standing charges for each fuel. If you don’t know your usage, use your last 12 months’ bills or ask your supplier.
FAQs: April 2026 price cap unit rates by region
When will the April 2026 price cap unit rates be published?
Ofgem typically publishes the next quarter’s cap shortly before it starts. For April–June 2026, expect publication in the weeks leading up to April. Always use Ofgem’s official tables for your region and payment method.
Why are unit rates different by region?
A major reason is that network charges (the cost of maintaining and operating local electricity and gas networks) vary across Great Britain. Ofgem reflects this in cap levels by region.
Does the price cap apply in Northern Ireland?
No. Ofgem’s default tariff cap applies to Great Britain (England, Scotland, Wales). Northern Ireland has a different market structure and regulators, so prices are set differently.
I’m on a fixed deal—does the cap limit my unit rates?
Usually not. The cap is mainly for default/SVT tariffs. Fixed tariffs follow your contract terms. If you’re thinking of leaving a fix, check exit fees and whether you’re within the switching window.
How do I know if I’m on a standard variable tariff?
Your bill or online account should show your tariff name and whether it’s “variable” or “fixed”. If your prices can change and you didn’t agree a fixed term recently, you’re often on an SVT/default tariff. Your supplier can confirm.
Do smart meters change the price cap rates I get?
A smart meter doesn’t automatically change cap levels. What matters is the tariff, payment method and meter configuration (e.g., prepay mode or Economy 7). Smart meters can make it easier to track usage and avoid estimated bills.
Can my supplier charge below the cap?
Yes. The cap is a maximum for default tariffs. Some suppliers may price below it, or offer fixed deals that work out lower for your usage. That’s why comparing based on your region and kWh can be worthwhile.
What if I don’t know my annual usage?
Use your last 12 months’ bills, your online account, or ask your supplier for your annual kWh. If you’ve just moved in, you can use a starting estimate, but treat any quote as indicative and adjust once you have readings.

How we assess “price cap unit rates by region”
Our approach is to help you reach the right conclusion for your household rather than quoting a single “average bill” figure.
- Inputs we prioritise: region, payment method, electricity meter type (single-rate/Economy 7), and annual kWh for each fuel.
- Calculation used: (unit rate × annual usage) + (standing charge × 365). We show this so you can replicate it with Ofgem’s April 2026 tables.
- Comparisons: we encourage comparing tariffs using the same usage assumptions, and including both unit rate and standing charge.
- Limitations: tariff availability, eligibility, and supplier-specific pricing can change; Economy 7 depends on your day/night split; VAT rules and billing periods can affect exact totals. All figures on this page are illustrative unless taken directly from Ofgem publications.
