April 2026 Ofgem price cap unit rates by region
A UK guide to what the Ofgem price cap means in practice: how unit rates and standing charges vary by region, meter type and payment method — and how to compare tariffs using your own usage.
- See how price-cap rates differ across England, Scotland and Wales (by Ofgem region).
- Understand what changes for Direct Debit vs prepayment, and for single-rate vs Economy 7.
- Use the quick form to compare whole-of-market tariffs using your postcode and details.
Price cap figures are set by Ofgem and can change each cap period. Rates shown are explained with assumptions and limitations — always confirm your exact rates on your bill or supplier quote.
Fast answer: why April 2026 price-cap rates vary by region
Ofgem’s price cap sets a maximum that suppliers can charge for unit rates (p/kWh) and standing charges (p/day) on default tariffs (like Standard Variable Tariffs) for households in Great Britain. The cap is not a single national rate: it varies by region (the electricity distribution area / gas region), payment method (e.g., Direct Debit vs prepayment), and meter set-up (single rate vs Economy 7).
If you’re on a fixed tariff, your unit rates can be below or above the cap — because the cap mainly applies to default tariffs. Always check your tariff name and rates on your latest bill or online account.
Key takeaway 1
Your postcode influences your cap rates because network costs differ by region.
Key takeaway 2
The cap limits prices, not your total bill — your bill still depends on kWh used.
Key takeaway 3
Economy 7 has day/night rates; the cap is set separately for each.

Compare tariffs against the April 2026 cap (postcode-led)
If you tell us your postcode, meter type and contact details, we can match you to available tariffs and show estimates based on your situation. This is the quickest way to see whether a deal is likely to beat a default tariff in your region.
Before you start: have a recent bill handy if possible. The most accurate comparisons use your annual kWh for electricity and gas (or a smart meter export).
- Electricity: annual kWh (or typical monthly usage)
- Gas: annual kWh (if you have gas)
- Your current tariff end date (if fixed)
Two realistic scenarios (illustrative)
Scenario A: single-rate electricity, medium use
Assume 3,100 kWh/year electricity, single-rate meter, Direct Debit. If a tariff is 5p/kWh cheaper than your current unit rate, the unit-rate part of your bill could be about £155/year lower (3,100 × £0.05), before standing charge differences and any discounts/fees.
Why this matters: small p/kWh changes add up quickly at typical usage levels.
Scenario B: Economy 7 (night-heavy), EV charging at home
Assume 4,200 kWh/year electricity with 55% night usage (2,310 kWh) and 45% day usage (1,890 kWh), Direct Debit. If an Economy 7 tariff offers night at 12p/kWh instead of 16p/kWh, that part alone is about £92/year lower (2,310 × £0.04), but higher day rates can reduce or erase the benefit.
Why this matters: with Economy 7, the day/night split is often the deciding factor.

We’ll use your details to contact you with options and estimated costs. You can ask questions before you decide. No pressure — just clarity.
Tip: If you’re on a fixed deal, check whether there’s an exit fee before switching. Some suppliers waive exit fees in the last ~49 days of a fixed term (varies by tariff).
April 2026 price cap unit rates by region: how to read them
Ofgem publishes price cap figures per region and payment method. On this page, we focus on what changes by region and how to use those numbers to judge whether a tariff is competitive for your home.
Important: The exact April 2026 cap tables (p/kWh and p/day) are only final once Ofgem publishes them for that cap period. If you’re reading this before publication, use this page as a framework and then plug in the official figures when available.
Typical UK regions used in Ofgem cap tables
Electricity is grouped by distribution region (often matching your network area). Gas is grouped by gas region. Your supplier uses your postcode to determine the correct region.
| Region (electricity distribution) | Where it broadly covers | What to check on your bill | Why it affects rates |
|---|---|---|---|
| Northern Scotland / Southern Scotland | Scotland (split by network) | Your electricity region/network area | Network and operating costs vary |
| North West / North East / Yorkshire | Northern England regions | Standing charge + unit rate lines | Regional network charges differ |
| East Midlands / West Midlands | Midlands | Payment method (DD / prepay) | Cap differs by payment method |
| Eastern / London / South East / Southern | South & London areas | Meter set-up (single vs E7) | E7 has separate day/night caps |
| South Wales / North Wales & Mersey | Wales regions | Electricity MPAN profile / tariff | Network costs and regional adders |
A practical way to use April 2026 cap rates (once published)
1) Find your region
Use your postcode (or your bill) to identify your electricity distribution region.
2) Match your payment method
Direct Debit and prepayment caps differ — compare like with like.
3) Use your kWh
Multiply kWh by unit rates and add standing charges to estimate annual cost.
4) Compare tariffs fairly
Check if a fix has exit fees, whether rates change at renewal, and any T&Cs.
If you already know your current rates, we can help you compare them in context.
Comparison table: what to check before you use cap rates
This table helps you avoid the most common “like-for-like” mistakes when comparing a supplier quote to Ofgem cap unit rates.
| What you’re comparing | What must match | Why it matters | Quick check |
|---|---|---|---|
| Unit rate (electricity) | Region + payment method + meter type | Cap varies across those inputs | Look for “p/kWh” on bill/quote |
| Standing charge | Same fuel (elec vs gas) + region | A lower unit rate can be offset by higher standing charge | Check “p/day” in quote |
| Economy 7 | Day rate + night rate + your usage split | A “cheap night” tariff can be expensive if day use is high | Estimate night % from meter reads |
| Fixed vs variable | Tariff type + term + exit fees | Cap is for default tariffs; fixes follow their contract rates | Check your “tariff end date” |
Decision checklist: who this guide suits (and who it doesn’t)
This guide is for you if:
- You’re on a Standard Variable Tariff and want to understand the cap in your area.
- You’re considering a fix and need a sensible baseline to compare against.
- You have Economy 7 or a smart meter and want to avoid “headline rate” traps.
- You’re moving home and need to sanity-check the default tariff you’re placed on.
This guide may not be enough if:
- You’re on a complex multi-rate set-up (e.g., legacy storage heating tariffs) and need a tailored check.
- You have a business meter or business contract (this page is home-only).
- You’re in Northern Ireland (price cap rules differ).
- You need help with debt, repayment plans or disconnection risk.
Costs, exclusions and common pitfalls (UK-specific)
Most confusion about the price cap comes from how it’s described in the news. Here are the points that most often catch households out.
Pitfall: thinking the cap is your total bill
The cap limits unit rates and standing charges. If you use more energy, you pay more — even under the cap.
Pitfall: comparing the wrong region
Two neighbours can have different cap rates if they fall into different distribution areas. Always compare using your postcode.
Pitfall: ignoring standing charge changes
A fix can look cheaper on p/kWh but still cost more overall if the standing charge is higher — especially for low users.
When the cap applies (and when it doesn’t)
- Applies: most default tariffs (e.g., SVT) for domestic customers in Great Britain.
- Usually doesn’t apply: fixed tariffs (rates set by contract), many specialist tariffs, and non-domestic supply.
- Northern Ireland: different market arrangements — this guide is for Great Britain.
Costs to watch for when switching
- Exit fees: common on fixed deals; check your tariff documents.
- Payment method assumptions: some quotes assume Direct Debit discounts.
- Economy 7 timings: night hours can vary; confirm your meter’s switching times.
- Meter changes: moving from prepay to credit can involve checks and time.
If you’re struggling to pay: the right next step may be help with bills, grants, or support schemes rather than switching alone. Citizens Advice explains emergency and ongoing help options.
FAQs
What exactly is the Ofgem price cap?
It’s a limit on the unit rates and standing charges suppliers can charge most households on default tariffs in Great Britain. It changes periodically and varies by region and payment method.
Does the cap apply if I’m on a fixed tariff?
Usually, no. Fixed tariffs follow the rates in your contract. Your fix can still be compared against cap-level rates to judge competitiveness, but it isn’t restricted by the cap in the same way.
Why do unit rates differ by region?
A significant part of your bill is made up of network and regional costs. Ofgem sets cap levels that reflect these differences across electricity distribution regions and gas regions.
What’s the difference between unit rate and standing charge?
The unit rate is what you pay per kWh you use. The standing charge is a daily fixed amount that covers things like maintenance and metering costs. Both can vary by region and payment method.
I have Economy 7 — which cap rates apply?
Economy 7 is usually capped with separate day and night unit rates (and a standing charge). To compare fairly, estimate your day/night split; the “best” tariff depends on when you use electricity.
Are prepayment cap rates the same as Direct Debit?
Not necessarily. Ofgem publishes separate caps for different payment methods. If you’re on prepay (including smart prepay), compare using prepay cap tables and prepay tariffs.
Can I switch if I owe my supplier money?
Sometimes, but it depends on your balance, payment method and supplier rules. If you’re in debt or on a repayment plan, get support first and check your options with your supplier or Citizens Advice.
How do I find my current unit rate and standing charge?
Check your latest bill, app, or online account. Look for “electricity unit rate (p/kWh)”, “gas unit rate (p/kWh)” and “standing charge (p/day)”. If you have Economy 7, you’ll see separate day and night rates.
We’ll use your postcode and meter details to match the right region and tariff types.

How we assess “price cap unit rates by region”
This page is designed to help you apply Ofgem’s published cap tables correctly. We focus on the user decisions that change outcomes: region, payment method, meter type and usage.
- Region matching: we assume your applicable region is determined by your postcode (electricity distribution area; gas region where relevant).
- Usage-based comparisons: we recommend using your annual kWh; where we show examples, they are illustrative and clearly labelled as such.
- No guaranteed savings: supplier pricing, availability, and terms can change; your final costs depend on actual usage and tariff conditions.
- Limitations: this page does not replace your supplier’s tariff information label, and it does not cover every niche meter arrangement (e.g., legacy multi-rate setups).
