Ofgem prepayment meter tariff rates (UK) this month
A UK-focused guide to what Ofgem’s price cap means for prepayment meters right now, how to estimate your costs, and when it’s worth comparing deals.
- See how prepayment prices are set under the Ofgem price cap (including the PPM discount)
- Estimate your monthly costs using your region and typical usage (with examples)
- Compare whole-of-market options safely (no promises, just clear next steps)
Figures on this page are estimates and depend on your region, meter type and usage. “This month” refers to the current Ofgem price cap period.
Fast answer: what are Ofgem prepayment meter tariff rates “this month”?
In the UK, most households on standard variable tariffs (SVTs) or default prepayment tariffs are priced in line with the Ofgem energy price cap. For prepayment meters (PPM), the cap is set with a slightly lower allowance than direct debit in many cases (often called the PPM discount), but your actual rates still depend on your region and whether you pay for electricity, gas, or both.
Key takeaways
- “This month” usually means the current cap period (Ofgem updates the cap on a schedule, not monthly).
- Your region matters: unit rates and standing charges vary across England, Scotland and Wales.
- PPM prices are capped on SVT/default tariffs, but fixed deals can be higher or lower.
- Standing charges still apply even if you use little energy.
What you’ll need to check your exact PPM rates
- Your postcode (for region)
- Whether you have gas, electric or dual fuel
- Your meter type (smart prepay / key / card)
- Whether you’re on SVT/default or a fixed tariff
Quick definition: “Ofgem cap” vs “your tariff”
- Ofgem price cap
- A limit on what suppliers can charge (for unit rate and standing charge) on SVT/default tariffs, set by Ofgem and varying by region and payment method.
- Your prepayment tariff rates
- The actual prices applied to your meter for each kWh used plus a daily standing charge—these should be at or below the cap if you’re on an SVT/default PPM tariff.
If you’re in a hurry
Use your postcode to compare PPM-compatible tariffs. We’ll show options across the market and what to look out for (exit fees, eligibility, meter changes).
Compare prepayment tariffsCompare prepayment options safely (whole of market)
If you’re on a prepayment meter, you may have fewer tariffs available than direct debit. Some suppliers still offer PPM-friendly tariffs, and in some cases you can switch tariff without changing meter—while other deals require a meter exchange or a move to credit billing.
What we’ll use to show accurate estimates
- Postcode to identify your electricity/gas region
- Contact details so we can send your results and help if you want to proceed
- We may ask about your meter type and typical usage next
How switching typically works for prepayment customers
- We check tariffs available for your meter/payment method in your region.
- You compare estimated costs (unit rates + standing charges) and terms.
- If you choose to switch, the new supplier handles the process (timescales vary).
- For some tariffs, you may be offered a meter change (only if you agree).

Two realistic cost scenarios (with assumptions)
These examples show how to estimate a monthly cost from unit rates + standing charges. Your actual tariff may differ by supplier, region, and cap period.
Scenario A: 1-bed flat, electricity only (PPM)
- Usage assumption: 1,800 kWh/year (typical low electricity use)
- Example tariff inputs (illustrative): 26p/kWh unit rate, 60p/day standing charge
Estimated energy cost: 1,800 × £0.26 = £468/year
Standing charge: 365 × £0.60 = £219/year
Total estimate: £687/year ˜ £57/month
Notes: electricity-only homes often feel standing charges more sharply because there’s only one fuel’s standing charge to spread across usage.
Scenario B: 3-bed house, dual fuel (PPM)
- Usage assumption: 3,100 kWh/year electricity and 12,000 kWh/year gas (medium use)
- Example tariff inputs (illustrative): Electricity 25p/kWh + 60p/day; Gas 6.5p/kWh + 32p/day
Electricity: (3,100 × £0.25) + (365 × £0.60) = £775 + £219 = £994/year
Gas: (12,000 × £0.065) + (365 × £0.32) = £780 + £117 = £897/year
Total estimate: £1,891/year ˜ £158/month
Notes: If your home uses more energy in winter (common), monthly costs can be much higher than the annual average.
Comparison: Ofgem-capped PPM (SVT) vs fixed deals vs changing payment method
Use this table to decide what to do next. Availability varies by supplier, credit checks, and meter type.
| Option | How prices are set | Pros | Watch-outs |
|---|---|---|---|
| Prepayment SVT / default tariff | Capped by Ofgem for your region and payment method. | No exit fees; prices move with the cap; widely available. | Rates can change when the cap changes; standing charges still apply; may not be the cheapest for your usage. |
| Fixed tariff that supports PPM | Supplier sets fixed unit rate/standing charge for a term (often 12–24 months). | Bill predictability; can be competitive versus future cap increases. | May have exit fees; not all suppliers offer PPM fixed deals; a fix can be higher than the capped SVT. |
| Move from PPM to credit / direct debit | You may access a wider range of tariffs; pricing varies by tariff type. | Potentially more tariff choice; easier budgeting via monthly payments. | May require eligibility checks; debt arrangements can affect options; meter exchange appointments may be needed. |
Decision checklist: switching or staying put
- Do you know your current unit rate and standing charge for gas/electric?
- Are you on a default/SVT (usually capped) or a fixed tariff?
- Do you have debt on the meter or repayment set-up?
- Would a meter change be acceptable if needed for a better tariff?
- Is your priority lowest estimated cost or price certainty?
Who PPM comparisons suit (and who they don’t)
Often suits you if:
- You’re on a default tariff and want to check alternatives
- You can provide usage or accept typical-usage estimates
- You’re open to a new supplier (and possibly a meter upgrade)
May not suit you if:
- You’re mid-fix with large exit fees
- You need short-term support—consider grants/aid first
- Your meter/paypoint set-up limits available suppliers (we’ll still check)
Costs, exclusions and common pitfalls (PPM-specific)
Prepayment is different from monthly billing. These are the most common reasons people get caught out when checking “this month’s” rates.
Standing charges are daily
Even if you use very little energy, you still pay a daily standing charge. This can make “low usage” savings smaller than expected.
Debt recovery can be built in
If you owe money, some top-ups may be split between energy and repayment. That affects how far your top-up goes—separate from tariff rates.
Not all deals support every meter
Some tariffs are only available for smart meters, or only for certain payment methods. We’ll flag any eligibility requirements.
“This month” vs cap period changes
If the price cap changes part-way through what you think of as “this month”, your supplier may apply the new rates from the cap start date. Always check the effective date on your supplier’s tariff information.
Unit rate comparisons can mislead
A lower unit rate doesn’t always mean a lower bill if the standing charge is higher (or vice versa). Compare using your estimated annual usage where possible.
FAQs: Ofgem prepayment meter tariff rates
Does Ofgem set my exact prepayment unit rate?
No. Ofgem sets a maximum allowed level for unit rates and standing charges on SVTs/default tariffs. Your supplier sets your actual rates within those limits, and they vary by region and fuel.
Are prepayment meter rates always higher than direct debit?
Not always. Under recent cap structures there has often been a PPM discount versus direct debit for the cap level, but your best option depends on your tariff availability, usage, and whether you can access credit billing.
What’s the difference between a smart prepayment meter and a key/card meter?
A smart prepayment meter can often be topped up online and may show prices in an app/in-home display. Traditional key/card meters usually require PayPoint/Payzone top-ups. Your tariff rates can be capped either way if you’re on a default/SVT PPM tariff.
Can I switch supplier if I have debt on my prepayment meter?
Sometimes, yes—but there can be rules and limits, and the debt may need to be handled as part of the switch. If you’re unsure, get guidance from Citizens Advice energy advice and ask your current supplier how repayments are set.
Do I pay VAT on prepayment energy?
Yes—domestic energy typically includes VAT at the domestic rate. Your receipts or online account may show how charges are applied. If you think VAT is incorrect, contact your supplier.
Why does my friend in another area have different PPM rates?
Electricity (and sometimes gas) costs vary by regional network area. Ofgem’s cap levels reflect these differences, so suppliers’ capped tariffs differ by postcode region.
Can my landlord force me to stay on prepayment?
Tenants’ rights and responsibilities can be nuanced. In many situations, you can choose your supplier and tariff, but there may be tenancy agreement conditions and practical constraints. If you’re renting, check your agreement and seek advice from Citizens Advice before arranging any meter changes.
How do I find my exact unit rate and standing charge on prepay?
Check your supplier’s online account/app, a tariff information page, or contact customer support. For smart prepay, the in-home display may also show tariff details. For key/card meters, your top-up receipt may include pricing info, but the supplier is the best source for current rates.
