Compare prepayment meter energy deals (whole-of-market)
If you’re on a prepayment meter (PPM), the way you pay can affect which tariffs are available and how your unit rates and standing charges are set. In 2026, Ofgem may adjust how PPM tariffs are treated under regulation — and suppliers can also change their own pricing and products.
Use EnergyPlus to compare domestic energy options across the market. We’ll help you check:
- Whether you can switch supplier while staying on PPM
- Whether you could move to a smart prepayment meter
- Whether you’re eligible to move to credit meter billing (where suitable)
Quick context: Ofgem doesn’t set one exact “tariff price” for everyone. It regulates parts of the market (including the price cap methodology) and suppliers then set tariffs within those rules.

So… will Ofgem change prepayment meter tariffs in 2026?
Possibly — but no one can guarantee the exact outcome until Ofgem publishes final decisions. What you can do is understand the areas Ofgem typically reviews and how those changes might affect prepayment meter standing charges and unit rates.
What Ofgem could look at for 2026
- Price cap methodology (how allowed costs are calculated)
- PPM vs credit pricing differentials (fairness between payment types)
- Standing charge structure and regional variation
- Debt-related PPM protections and consumer outcomes
- Smart meter/PPM rules and how quickly changes can be implemented
What may not change (or changes slowly)
- Your meter type won’t automatically change without your supplier’s process
- Regional network costs still vary around the UK
- Supplier tariffs will continue to differ by product and risk pricing
- Eligibility rules for switching can depend on debt and meter setup
If your goal is to pay less, the practical move is to keep comparing what’s available for your postcode and circumstances — and act when a better option appears.
Why prepayment meter tariffs can look different
Prepayment customers often ask why their prices can differ from direct debit or standard credit. It usually comes down to cost-to-serve, payment risk assumptions, and how tariffs are structured — all within the rules suppliers must follow.
Payment method and risk
Some tariffs price in the risk of missed payments. PPM removes ongoing billing risk, but debt recovery and top-up systems can add complexity.
Top-up and metering costs
Traditional key/card systems and certain support processes can cost more than automated billing, while smart PPM can change how service is delivered.
Standing charges
Standing charges include fixed costs such as network and policy costs. They vary by region and can be a big factor for low-usage households.
Tip: When comparing PPM tariffs, don’t focus on unit rate alone. Your standing charge, payment type, and typical usage determine what you pay overall.
Ofgem price cap vs your prepayment tariff: what’s the difference?
The Ofgem price cap (when in effect for your tariff type) limits the maximum a supplier can charge for default tariffs, based on typical consumption. It doesn’t mean everyone pays the same amount — and it doesn’t automatically make every deal cheap.
| Item | What it means for PPM customers | What you can do |
|---|---|---|
| Default tariff cap | Limits prices on certain default tariffs (including many PPM standard tariffs). Levels can change each period based on costs. | Check if you’re on a capped default tariff, then compare alternatives if switching is allowed. |
| Fixed tariffs | A fixed deal can protect you from short-term rises, but may be higher than the current cap and can have exit fees. | Compare total annual cost and check exit fees before switching. |
| Standing charge | Daily charge regardless of usage; varies by region and tariff. It can be significant for low usage. | Compare standing charges and consider usage-reducing measures to offset fixed costs. |
| Payment type | PPM, direct debit and credit tariffs can be priced differently depending on product availability and costs. | Ask whether you can move to smart PPM or credit meter billing if appropriate. |
Important: If you’re repaying energy debt via your meter, your top-ups may include deductions. Comparing tariffs can still help, but debt arrangements can affect what you feel week to week.
How to reduce prepayment meter energy costs in 2026
Regardless of whether Ofgem changes PPM tariff rules in 2026, these practical steps can help you stay in control of spending.
-
Compare your current tariff against the market
Prices can change across suppliers and tariff types. Use your postcode to check what’s available for your meter type and region.
-
Check whether smart prepayment is an option
Smart PPM can allow top-ups and meter management without visiting a shop, and may make it easier to access certain features and support.
-
Review standing charges and total cost (not just unit rates)
If your usage is low, a higher standing charge can outweigh a slightly lower unit rate. Always compare the estimated annual cost.
-
Use targeted home energy efficiency actions
Draught-proofing, thermostat schedules, radiator balancing and LED lighting can reduce usage without major renovations.
Regional differences: why your postcode matters
Energy prices aren’t identical across the UK. Even on similar tariffs, your standing charge and sometimes unit rates can differ by region due to network and distribution costs.
What this means in practice
- Two households using the same energy can have different bills in different areas.
- Comparisons are more accurate when based on your postcode and meter type.
- Standing charge changes can have a bigger impact in some regions than others.
What to check before switching
When you compare, look for:
- Estimated annual cost based on your usage (kWh)
- Standing charge (per day) and unit rates (per kWh)
- Tariff length, exit fees and payment method
Common mistakes when checking prepayment meter tariffs
Comparing by unit rate only
Unit rates matter, but standing charges and usage patterns can swing the total. Always compare estimated annual cost.
Assuming you can’t switch on PPM
Many households can switch suppliers or tariffs even on PPM. Eligibility can depend on meter type and debt status.
Missing the tariff terms
Fixed deals may include exit fees and conditions. Make sure the price certainty is worth it for your situation.
FAQs: Ofgem, prepayment meters and 2026
Does Ofgem set prepayment meter prices?
Ofgem regulates parts of the market (including the price cap methodology for default tariffs). Suppliers still set their own tariffs and decide what to offer, within the rules.
Could PPM standing charges change in 2026?
They could. Standing charges can change due to network costs, policy costs and regulatory methodology. Comparing your options helps you see the impact for your postcode.
Is it cheaper to be on direct debit than prepay?
Not always. Some direct debit deals can be cheaper, but availability depends on your circumstances and supplier criteria. The best approach is to compare total costs.
Can I switch if I have debt on my prepayment meter?
Sometimes. It can depend on the amount of debt, whether it’s being repaid through the meter, and supplier policies. If you’re unsure, submit your details and we’ll guide you through likely options.
Will a smart meter automatically lower my bills?
A smart meter doesn’t automatically make energy cheaper, but it can help with accurate billing, better visibility of usage, and may support smart prepayment features.
What information do I need to compare tariffs?
Your postcode is a great start. For best accuracy, have your current supplier, meter type (PPM/smart PPM), and approximate annual usage in kWh (if available).
