Ofgem April 2027 price cap: what will I pay?
A UK-focused guide to what the Ofgem price cap can (and can’t) tell you about your likely bills in April 2027 — plus how to estimate your own costs and compare tariffs with confidence.
- Understand what the price cap covers (and what it doesn’t)
- See example costs for two realistic household scenarios
- Get a clear checklist for deciding whether to stay on SVT, fix, or switch
Estimates only. The price cap changes regularly and depends on region, meter type and payment method. Your actual bill depends on usage (kWh).
Fast answer: can you know what you’ll pay under the April 2027 price cap?
Not precisely. The Ofgem price cap for April 2027 isn’t available yet and can’t be predicted with certainty. Even when the cap is published, it’s not a cap on your total bill — it caps the unit rates (p/kWh) and standing charges (p/day) on default tariffs, which are then applied to your usage.
What you can do today: estimate your likely costs by (1) using your annual consumption in kWh, (2) applying the latest available capped unit rates for your region/meter type (as a proxy), and (3) stress-testing the result with a sensible “higher / lower” range.
Key takeaways (UK households)
- April 2027 is part of the Apr–Jun quarter (Q2). Ofgem updates the cap quarterly.
- The cap level varies by region, payment method and meter type (single-rate vs Economy 7, smart vs traditional).
- Your bill depends on how many kWh you use — two homes in the same street can pay very different amounts.
- Fixes can be above or below the cap. The right choice depends on risk tolerance, contract terms and usage patterns.
Estimate what you’ll pay in April 2027 (step-by-step)
Because April 2027 rates aren’t published, the most honest approach is to build an estimate range using the latest available cap information as a proxy and your own usage.
- Find your annual usage (kWh) for gas and electricity. Use your bill, online account, or your smart meter app. If you’ve moved recently, use a realistic estimate.
- Check your setup: region, payment method, meter type (single-rate or Economy 7), and whether you’re on a standard variable tariff (SVT) or fixed tariff.
- Apply a price assumption (unit rate + standing charge). For April 2027, treat this as a placeholder until Ofgem publishes the actual quarter’s cap.
- Stress-test the result with a higher/lower scenario (for example ±10–20%) to reflect uncertainty.
Important: the price cap applies to default tariffs (including SVTs), not to every deal. If you’re on a fixed tariff, your rates are set by your contract until it ends.
Two realistic scenarios (illustrative numbers)
These are worked examples to show the method, not a prediction of April 2027 rates. We use a simple assumption set and show the maths so you can swap in your own figures.
Scenario A: flat / small house (low–medium use)
- Assumed annual usage
- Electricity 2,000 kWh; Gas 8,000 kWh
- Assumed rates (illustrative)
- Elec 28p/kWh + 60p/day; Gas 7p/kWh + 32p/day
- Estimated annual cost (rough)
- Elec: (2,000×£0.28) + (365×£0.60) = £560 + £219 = £779
Gas: (8,000×£0.07) + (365×£0.32) = £560 + £117 = £677
Total ≈ £1,456/year (about £121/month)
Scenario B: family home (medium–high use)
- Assumed annual usage
- Electricity 3,600 kWh; Gas 12,500 kWh
- Assumed rates (illustrative)
- Elec 28p/kWh + 60p/day; Gas 7p/kWh + 32p/day
- Estimated annual cost (rough)
- Elec: (3,600×£0.28) + (365×£0.60) = £1,008 + £219 = £1,227
Gas: (12,500×£0.07) + (365×£0.32) = £875 + £117 = £992
Total ≈ £2,219/year (about £185/month)
Caveat: standing charges and unit rates vary by region and payment method. Economy 7 users have day/night rates. These examples use single-rate electricity and direct debit-style pricing for simplicity.

Tip for April 2027 planning: if your fixed deal ends near spring 2027, check the tariff end date and any exit fees now so you can time any switch.
Price cap vs fixed tariff: what’s the practical difference?
If you’re asking “what will I pay in April 2027?”, you’re usually deciding whether to remain on a capped standard variable tariff (SVT) or choose a fixed deal. This table focuses on the things that change what you actually pay.
| Feature | Price-capped SVT (default tariff) | Fixed tariff |
|---|---|---|
| How prices change | Unit rates/standing charges can change each quarter with the cap. | Rates stay the same for the fix term (unless contract allows otherwise). |
| Bill certainty | Lower certainty: your rates can change; your usage still drives the bill. | More certainty on rates; your usage still drives the bill. |
| Exit fees | Typically none on SVT (check supplier terms). | Often applies if you leave before the end date. |
| Who it can suit | People who want flexibility and don’t mind rates changing. | People who prefer predictable rates and are happy to commit for the term. |
| Key watch-outs | Standing charges differ by region; Economy 7 complexity; variable rates can rise. | Exit fees; what happens at end of term; whether it’s truly fixed for both fuels. |
Decision checklist: it may suit you to stay capped if…
- You want flexibility to switch without worrying about exit fees.
- You expect you might move home before spring/summer 2027.
- You’re comfortable with rates changing quarter to quarter.
- You prefer not to commit while you gather better usage data.
Decision checklist: it may suit you to fix if…
- You value stable unit rates more than flexibility.
- You’ve checked the exit fees and they’re acceptable for your plans.
- You have higher usage and want to reduce the risk of quarter-to-quarter increases.
- You’ve confirmed what happens when the fix ends (avoid rolling onto an expensive default).
Quick “sanity check” before you decide
- Are the rates quoted for your region (not a national headline figure)?
- Is your meter single-rate or Economy 7 (and are the right rates shown)?
- Is the tariff for direct debit or another payment method?
- Does the tariff include any bundles (e.g., boiler cover) that change value for you?
Costs, exclusions and common pitfalls (April 2027 planning)
When people ask “what will I pay under the April 2027 cap?”, the biggest surprises usually come from the details below.
1) The cap isn’t a “max bill”
It caps unit rates and standing charges for default tariffs. If you use more energy, you pay more — even under the cap.
2) Standing charges can dominate low usage
If you’re rarely home or have a very efficient property, standing charges can form a large share of your annual cost.
3) Region matters (a lot)
Ofgem sets different cap levels by electricity distribution region. Two households with the same usage can pay different amounts purely due to region and charges.
4) Payment method affects pricing
Direct debit rates can differ from standard credit or prepayment meter (PPM) pricing. Always compare like-for-like.
5) Economy 7 and smart tariffs need extra care
If you have Economy 7, your split between day/night usage heavily changes costs. Smart time-of-use tariffs can be great for some homes, but they’re not “cap-based” in the same way.
6) Exit fees and end dates
If you fix now and want to change before April 2027, check whether leaving early costs money and when the supplier can apply it.

FAQs
When will Ofgem publish the April 2027 price cap?
The April cap covers the April–June quarter. Ofgem typically publishes new cap levels ahead of the quarter starting. Until then, any “April 2027 cap” figure is a guess.
Is the price cap the same across the UK?
No. Cap rates vary by electricity distribution region, and can also vary by payment method (e.g. direct debit vs prepayment) and by meter setup.
Does the cap apply to fixed tariffs?
No. The cap mainly limits prices on default tariffs (including SVTs). Fixed tariffs are governed by contract terms, which can be above or below the capped default rates.
Why do headlines quote an “average annual bill” under the cap?
It’s a communication shortcut based on a typical household usage assumption. Your real cost depends on your kWh usage, standing charges, and your region. Treat headlines as context, not your bill.
I have a prepayment meter — will I pay the same as direct debit?
Not necessarily. Ofgem publishes separate cap levels for different payment methods. If you’re on PPM, compare tariffs and cap information specifically for prepayment where available.
What if I only use electricity (no gas)?
Your costs will depend heavily on electricity usage, standing charges, and whether you’re on single-rate, Economy 7, or a time-of-use tariff. Compare electricity-only deals carefully because standing charges still apply.
If I switch now, will it affect what I pay in April 2027?
It can. If you take a fixed tariff that runs into 2027, your April 2027 rates will usually be the fixed rates (subject to terms). If you’re on an SVT then, your rates will track whatever the cap is for that quarter.
Can my supplier charge above the cap?
On a default tariff covered by the cap, suppliers must keep unit rates and standing charges within the cap for your region/meter/payment type. On fixed or special tariffs, different rates can apply by contract.

How we assess “what will I pay?” (transparent methodology)
This page is designed to answer a forward-looking question responsibly. Because April 2027 rates are unknown today, we focus on how to estimate rather than claiming a specific figure.
- We use kWh-based maths: annual cost ≈ (electricity kWh × unit rate) + (365 × electricity standing charge) + (gas kWh × unit rate) + (365 × gas standing charge).
- We separate “cap” from “bill”: the cap limits unit rates and standing charges on default tariffs; your bill still depends on consumption.
- We call out key variables: region, payment method, meter type (including Economy 7), and tariff type (SVT vs fixed).
- We show worked examples: scenarios use illustrative rates solely to demonstrate calculation and decision-making.
- Limitations: we cannot predict wholesale prices, network costs, or policy changes that may influence future cap levels. Any estimate for April 2027 should be treated as a range.
Want a clearer idea of what you could pay?
Compare available home energy tariffs using your postcode and preferences. You’ll see rates and key terms so you can decide before April 2027 approaches.
Note: the secondary button returns you to the estimate section. Tariff availability and prices vary by region, meter type and supplier terms.
