Ofgem price cap January 2027: what will I pay?
A UK-focused guide to what the January–March 2027 Ofgem price cap could mean for your monthly bill, why it varies by home, and how to get a personalised whole-of-market quote.
- What the cap is (and isn’t), and why your bill won’t match headlines
- How to estimate your own costs using your region, meter type and usage
- When a fixed tariff may beat the cap — and the risks to check first
Figures on this page are estimates and examples. The Ofgem cap changes every quarter and your actual costs depend on usage, region, meter type and payment method.
Fast answer: January 2027 bills depend on the cap — and on you
You can’t know exactly what you’ll pay under the Ofgem price cap for January–March 2027 until Ofgem publishes it. Even then, two households under the same cap can pay very different amounts because the cap is set using unit rates (p/kWh) and a standing charge (p/day) that vary by:
- Region (distribution area)
- Payment method (Direct Debit, cash/cheque/prepayment)
- Meter type (single-rate vs multi-rate, e.g. Economy 7 where available)
- Your usage (kWh used for gas and electricity)
Important: The Ofgem price cap is not a cap on your total bill. It limits the maximum price suppliers can charge per unit and per day for standard variable tariffs in each region, not what you spend overall.
Key takeaways (what to do now)
1) Find your usage
Grab a recent bill or annual statement. You need kWh for electricity and (if you have it) gas.
2) Check your meter type & payment method
Single-rate vs Economy 7, smart meter, and whether you pay by Direct Debit can materially change rates.
3) Compare to fixed deals
The cap can rise or fall each quarter. Fixed tariffs can add certainty, but check exit fees and terms.
Estimate what you’ll pay under the January 2027 price cap
Once Ofgem publishes the January–March 2027 cap, you can estimate your annual cost with a simple formula. This helps you sanity-check supplier quotes and understand why “typical bill” headlines don’t match your home.
The calculation (what the cap actually limits)
- Electricity cost (estimated)
- (Electricity unit rate × your electricity kWh) + (electricity standing charge × 365)
- Gas cost (estimated)
- (Gas unit rate × your gas kWh) + (gas standing charge × 365)
Add the two together for an annual estimate, then divide by 12 for a rough monthly figure. (Bills are seasonal, so winter months are usually higher.)
Reality check: Ofgem’s cap applies to standard variable tariffs. If you’re on a fixed tariff or a special tariff (for example, certain tracker tariffs), the price cap doesn’t set your exact rates — though it can influence market pricing.
Two realistic scenarios (with numbers)
These examples are illustrative to show the maths. They are not a prediction of the January 2027 cap.
Scenario A: low-to-medium use flat (dual fuel)
- Electricity use: 2,000 kWh/year
- Gas use: 10,000 kWh/year
- Example capped rates used: electricity 28p/kWh, standing charge 55p/day; gas 7p/kWh, standing charge 32p/day
Electricity: (0.28×2,000) + (0.55×365) ≈ £761/year
Gas: (0.07×10,000) + (0.32×365) ≈ £817/year
Total: ≈ £1,578/year (about £132/month on average)
Assumes rates apply consistently (in reality, your unit rates can change each quarter on a variable tariff).
Scenario B: higher-use family home (dual fuel)
- Electricity use: 3,600 kWh/year
- Gas use: 15,000 kWh/year
- Same example capped rates as above (for illustration)
Electricity: (0.28×3,600) + (0.55×365) ≈ £1,209/year
Gas: (0.07×15,000) + (0.32×365) ≈ £1,167/year
Total: ≈ £2,376/year (about £198/month on average)
Higher usage increases your total far more than small changes to standing charges.
Caveat for electricity-only homes: If you don’t have mains gas (or you heat with electric), your electricity usage can be much higher than these examples — and the “typical dual fuel bill” figures you see in the news may be misleading for your situation.

Price cap vs fixed tariff: what’s the practical difference?
Many people ask “Should I wait for the January 2027 cap?” The cap can help prevent extreme pricing on standard variable tariffs, but it doesn’t guarantee the cheapest deal. A fixed tariff can be lower or higher than the cap and may include an exit fee.
| Feature | Capped SVT (price cap applies) | Fixed tariff |
|---|---|---|
| What changes your price | Rates can change when the cap changes (quarterly) and when suppliers update SVT prices | Unit rates usually fixed for the term (e.g. 12 months), subject to contract terms |
| Budget certainty | Medium: you’re protected by a cap, but quarterly movement can affect bills | Higher: rates are usually stable for the term |
| Potential to be cheapest | Sometimes, especially if fixed deals are priced above the cap | Sometimes, especially if you lock in below-cap rates and the cap rises |
| Exit fees | Typically none | Often applies (varies by supplier and product) |
| Best for | People who want flexibility and to avoid exit fees | People who prioritise predictable rates and are happy with the term |
Decision checklist: who it suits (and who it doesn’t)
A capped SVT may suit you if…
- You might move home soon (renters often prefer flexibility)
- You don’t want to risk paying an exit fee
- You’re waiting for better fixed deals and want a regulated default in the meantime
- You’re unsure whether your meter setup needs changes (e.g. E7 changes, smart meter issues)
A fixed tariff may suit you if…
- You want steadier unit rates for budgeting
- You’ve found a deal that’s competitive for your usage (not just “typical” figures)
- You’re comfortable committing for the term and understand any exit fees
- Your household uses a lot of energy and you want to reduce exposure to quarterly changes
Either option may be a poor fit if…
- You have debt with your current supplier and need an agreed repayment plan first
- You’re on a complex multi-rate or legacy meter arrangement and rates are hard to compare
- You’re on prepayment and topping up is difficult — you may need extra support options
Tip: When comparing deals, focus on unit rates and standing charges for your region and payment method, then sanity-check against your own kWh usage — not just the supplier’s “estimated annual cost”.
Costs, exclusions and common pitfalls (UK-specific)
Most confusion about the January 2027 cap comes from how it’s reported and how bills are built up. These are the biggest “gotchas” to watch.
1) Headline “typical bill” isn’t your bill
News coverage often uses a “typical household” usage figure. If you’re electricity-only, have a heat pump, an EV, work from home, or have more/less occupants, your costs can be very different.
2) Standing charges can be a big slice
Even with low usage, standing charges still apply. If you’re rarely at home or you’re trying to minimise usage, compare standing charges carefully alongside unit rates.
3) The cap varies by region & payment type
There isn’t one universal set of capped rates. Rates can differ across Great Britain’s electricity distribution regions and between Direct Debit vs prepayment.
4) Economy 7 / multi-rate tariffs need careful comparison
If you have off-peak rates (e.g. storage heaters), the split between day and night usage matters. A tariff with a very low night rate but high day rate can cost more if your usage pattern changes.
5) Fixed tariff exit fees
If you’re fixed now, check your contract end date and any exit fee. If January 2027 rates look better, leaving early could reduce or eliminate any benefit.
6) Arrears and switching
If you owe money to your supplier, switching may be restricted depending on your meter type and debt situation. Get support early and agree an affordable repayment plan.
If you’re struggling to pay: you may be eligible for help such as the Warm Home Discount (if available/eligible), supplier hardship support, or debt advice. Start with Citizens Advice guidance on energy bills and support.

FAQs: Ofgem price cap January 2027
When will the January–March 2027 price cap be announced?
Ofgem typically publishes each new cap shortly before the quarter starts. For the latest publication dates and figures, check Ofgem’s official price cap pages.
Does the price cap apply to fixed tariffs?
Not directly. Fixed tariff rates are set by your contract. The cap applies to standard variable tariffs and certain default tariffs, with specific rules. Fixed deals can be above or below the cap.
Why is my friend’s “capped” price different to mine?
Capped rates vary by region, payment method and meter type. Two people can both be “on the cap” and still see different standing charges and unit rates.
Is the price cap the same in Northern Ireland?
No. The Ofgem price cap applies to Great Britain (England, Scotland, Wales). Energy in Northern Ireland is regulated differently.
If the cap goes down in January 2027, will my direct debit drop automatically?
Not always. Suppliers set Direct Debits based on expected annual costs and your account balance. If rates fall, you can ask your supplier to review your Direct Debit — especially if you’re building credit.
What if I’m on a prepayment meter — am I covered?
Yes, there is a cap level for prepayment, but the exact rates can differ from Direct Debit. If you’re struggling to top up, seek support quickly — suppliers have obligations to help vulnerable customers.
Can I switch supplier if I’m renting?
Usually yes, if you pay the energy bills and your tenancy agreement doesn’t include energy as part of the rent. If you’re unsure, check your agreement or ask your landlord/agent.
Is it worth waiting for January 2027 before fixing?
It depends on today’s fixed deals, your usage, and whether you’d pay an exit fee to leave your current tariff. The cap is updated quarterly, so “waiting” can mean staying exposed to changes. Comparing options now gives you clarity.

How we assess “what will I pay?” (our methodology)
This guide is designed to answer a forward-looking question responsibly. We don’t guess the January 2027 cap figure. Instead, we explain how your bill is constructed and how to estimate costs once Ofgem publishes the rates.
- We focus on the components Ofgem caps: unit rates (p/kWh) and standing charges (p/day) by region, payment method and meter type.
- We use kWh-based examples: scenarios show the calculation using illustrative rates, clearly labelled as examples (not forecasts).
- We highlight variation drivers: usage differences, Economy 7 patterns, electricity-only heating, and prepayment vs Direct Debit.
- We avoid “savings claims”: fixed tariffs may be cheaper or dearer; eligibility and pricing vary by supplier and customer details.
Limitations: Your real bill includes VAT and can be affected by billing cadence, seasonal use, and account balance if you pay by Direct Debit. Some tariffs have additional terms (e.g. bundled services) that change overall value.
Want a clearer answer than a headline cap figure?
Compare whole-of-market options using your postcode and preferences — then decide whether to stay on a capped tariff or fix for peace of mind.
