Fast answer: what to expect for the Ofgem price cap in April 2026

The Ofgem price cap for April–June 2026 (often called the “April 2026 price cap”) applies to most households on a default tariff—typically a supplier’s Standard Variable Tariff (SVT) and some default tariffs after a fix ends. It does not set your total bill; it limits the maximum unit rates (pence per kWh) and standing charges your supplier can charge for those capped tariffs, which means your bill still depends on your usage.

Key timing: Ofgem normally publishes each new cap level around 6 weeks before it takes effect. So April 2026 rates are typically announced in mid-to-late February 2026 (exact date varies).

What’s capped

  • Unit rates (electricity and gas)
  • Standing charges
  • Different levels by region & payment method

What’s not capped

  • Your total bill (usage-driven)
  • Most fixed tariffs (suppliers set those prices)
  • Non-domestic/business energy contracts

Most useful action

If you’re on SVT, compare like-for-like with any fixes available for your postcode and meter setup—then weigh up price certainty versus flexibility.

Not sure if you’re capped? If your tariff name includes “Standard Variable”, “Flexible”, “Default”, or you’ve rolled off a fix, you’re often on a capped tariff. Your latest bill/app should show the tariff name and whether it’s fixed or variable.

How the Ofgem price cap works (in plain English)

The price cap is a consumer protection measure. It sets a limit on the maximum prices suppliers can charge for default tariffs. It’s recalculated regularly using a formula designed by Ofgem, reflecting wholesale energy costs and other allowed costs.

Important: News headlines often quote an “average annual bill” figure. That figure is an illustration based on a typical household usage value, not a promise of what you will pay.

Why your cap level can differ from someone else’s

  • Region: standing charges and network costs vary across Great Britain’s electricity regions.
  • Payment method: direct debit vs standard credit vs prepayment can have different capped rates.
  • Meter type: smart meter, traditional credit meter, or prepayment meter; some tariffs also vary by profile class.
  • Fuel: electricity-only, gas-only, or dual fuel all calculate differently.

When April 2026 changes show up on your bill

If you’re on a capped tariff, your supplier normally applies the new unit rates/standing charges from 1 April 2026. Bills that cover dates either side of 1 April are usually split (part charged at old rates, part at new rates).

If you’re on a fixed tariff, your rates typically stay the same until your fix ends (unless your contract terms say otherwise).

Quick check: are you likely on the cap?

Your tariff says “Standard Variable” / “Flexible”
Usually yes (capped).
You recently ended a fixed deal
Often moved to a default tariff (capped) unless you chose another fix.
You’re on a fixed tariff with an end date
Usually no (fixed tariffs aren’t price-capped, though they’re regulated in other ways).
You’re on an Economy 7 / multi-rate tariff
You may still be capped, but the structure is different (day/night rates). Compare carefully.

Compare tariffs for your home (and keep April 2026 in perspective)

If the April 2026 cap rises, a fix could help with price certainty. If it falls, a long fix could mean you pay more than a variable tariff for a while. The right choice depends on your usage, risk tolerance, and tariff terms (especially exit fees).

What we’ll ask for (and why)

  • Postcode (regional network costs affect rates)
  • Contact details so we can send your comparison and next steps
  • Your supplier / tariff / meter details later if needed for accuracy

Tip: Have a recent bill to hand. If you can find your unit rates and standing charges, you’ll be able to compare more precisely than with “average bill” headlines.

Two realistic scenarios (illustrative numbers)

These examples show how the same cap change can affect different homes. We use simplified assumptions and rounded figures to keep it readable.

Scenario A: low-usage flat (electricity-only)

  • Usage assumption: 2,000 kWh/year electricity
  • Standing charge assumption: 55p/day
  • Unit rate assumption (before April): 24p/kWh
  • Illustrative cap change in April 2026: +10% on unit + standing

Estimated impact: about +£55/year (roughly +£4.60/month), mainly driven by the unit rate and standing charge uplift.

Calculation: (2,000×24p + 365×55p)=£681 ? +10% ˜ £749 (+£68). Rounded and illustrative; real cap changes are not uniform like this.

Scenario B: family home (dual fuel, higher gas use)

  • Usage assumptions: 3,000 kWh/year electricity + 12,000 kWh/year gas
  • Standing charge assumptions: 55p/day elec + 30p/day gas
  • Unit rate assumptions: 24p/kWh elec + 6p/kWh gas
  • Illustrative cap change in April 2026: +10% on unit + standing

Estimated impact: about +£130/year (roughly +£11/month). Homes with more gas use can see larger swings.

Calculation: Elec £924 + Gas £829 ˜ £1,753 ? +10% ˜ £1,928 (+£175). Rounded and illustrative; actual cap changes vary by component and region.

Why these are only examples: The Ofgem cap is set using multiple cost components and differs by region and payment type. A real cap update may increase one component and reduce another.

If you’re already on a fix: check the end date and any exit fees. Many suppliers let you switch near the end of a fix without penalty, but terms vary—confirm with your supplier.

Price cap vs fixed tariff: a practical comparison

Use this table to decide what to do before April 2026. It focuses on household realities: exit fees, payment method, and how confident you are about near-term price moves.

What you care about Staying on SVT (price-capped) Switching to a fixed tariff Best for…
Price changes Can go up or down each cap period (e.g., Apr–Jun). Typically stays the same until your fix ends. People who want flexibility vs people who want certainty.
Exit fees Usually no exit fee (check tariff terms). Often has exit fees (especially longer fixes). People who may move home or want the option to change quickly.
Direct debit vs prepay Cap varies by payment method; prepay has its own cap. Not all fixes are available for every payment type/meter. Anyone who needs a tariff compatible with their meter/payment setup.
Budgeting More variable—changes at cap updates. More predictable monthly costs (usage still matters). Households who prefer stable planning.
Risk if prices fall You benefit automatically at the next cap reset. You could be stuck paying more until the fix ends (unless you pay exit fees). People who think prices may fall and want to keep options open.

Decision checklist (quick and honest)

  • Check your tariff type: SVT/variable vs fixed (look on your bill/app).
  • Note your end date (if fixed) and any exit fees.
  • Find your unit rates and standing charges (electricity + gas).
  • Confirm meter/payment type: credit, prepay, Economy 7, smart, etc.
  • Compare on total cost: not just unit rate—standing charges matter.
  • Be realistic about usage: especially gas use over winter vs summer.

Who it suits / who it doesn’t

A fixed tariff may suit you if…

  • You want predictable pricing through spring/summer 2026
  • You’re worried about a cap rise and value certainty
  • You’re happy to commit and accept possible exit fees

Staying on the capped SVT may suit you if…

  • You may move home soon
  • You want flexibility if prices fall later
  • You don’t want to risk exit fees

Note: some properties (e.g., restricted meters, certain prepayment setups) have fewer tariff options. We’ll highlight availability when you compare.

Costs, exclusions and common pitfalls (April 2026 planning)

A lot of confusion comes from mixing up the cap, fixed tariffs, and “average bill” figures. Here are the most common trip-ups we see—and how to avoid them.

1) Assuming the cap is your bill

The cap limits prices, not your total spend. If your usage is above typical levels, your bill can still be high.

2) Ignoring standing charges

Standing charges are paid regardless of use and vary by region and payment type. A lower unit rate doesn’t always mean a lower total cost.

3) Not checking meter compatibility

Economy 7 and some restricted meters can limit tariff choice. Always compare tariffs that match your exact meter setup.

4) Missing exit fees and end dates

Some fixes have exit fees per fuel. If you switch early, that cost can wipe out any benefit—check your terms first.

5) Confusing direct debit amount with tariff cost

Your direct debit can be adjusted to manage debt/credit. Compare tariffs using unit rates + standing charges, and your annual usage if possible.

6) Expecting the same cap across the UK

The cap varies by region (and by GB vs Northern Ireland arrangements). Always use postcode-based comparisons.

Households on prepayment: you’re protected by the cap too, but tariff choice can be narrower. If you’re struggling to pay, consider independent support from Citizens Advice (see sources below).

FAQs: Ofgem price cap April 2026

When will the April 2026 Ofgem price cap be announced?

Ofgem typically publishes the next cap level around 6 weeks before it starts. For April 2026, that’s usually mid-to-late February 2026. Exact timing can vary.

Does the cap apply to fixed tariffs?

Generally no. Fixed tariffs usually aren’t capped because you’re agreeing a set price for a term. The cap mainly applies to default tariffs like SVTs.

If the cap goes down in April 2026, will my bills drop?

If you’re on a capped variable tariff, your unit rates/standing charges should reduce in line with the new cap (subject to your region and payment method). Your actual bill will still depend on usage.

Why do headlines quote an “average annual bill”?

It’s a standardised illustration based on a typical annual usage figure. It helps compare cap periods, but it isn’t personalised. Two households in the same area can pay very different amounts.

Does my region affect the April 2026 cap?

Yes. The cap varies across Great Britain’s electricity regions because network costs differ. That’s why postcode-based comparisons are more reliable than national averages.

I’m on prepayment—am I covered by the cap?

In most cases, yes—there is a cap for prepayment meters. However, tariffs and switching options can differ. If you’re in difficulty, independent help is available via Citizens Advice.

Can suppliers charge more than the cap?

For tariffs that are covered by the cap, suppliers must stay within the maximum allowed unit rates and standing charges (for your region/payment type). Fixed tariffs can be priced differently because they’re not capped in the same way.

Will switching affect my supply?

Switching supplier shouldn’t interrupt your gas or electricity supply. It’s an administrative change. Timelines vary, and you should still provide meter readings if asked.

Trust, methodology and sources

Page ownership

We update this page when Ofgem publishes the cap level for April–June 2026 and when suppliers materially change tariff availability.

How we assess “what it could mean” (our assumptions)

  • Cap timing: based on Ofgem’s typical publication schedule (around 6 weeks ahead). Dates can shift.
  • Examples: we use simplified unit rates, standing charges, and a single illustrative percentage change to show sensitivity. This is not a forecast of April 2026 rates.
  • Usage: scenario usage values are rounded for clarity and may not match your home.
  • Regional variation: we highlight that the cap differs by region/payment type; exact rates require postcode and meter/payment details.
  • What we don’t do on this page: we don’t predict the cap level or guarantee savings; we focus on decision-ready guidance and the factors you can control.
