Can I change to a cheaper prepayment tariff in the UK? (Updated for the July 2026 cap)

Yes — in many cases you can move to a cheaper prepayment (PAYG) tariff without changing your meter, and prepayment customers are now protected by the same Ofgem price cap as Direct Debit households. Compare whole-of-market options with EnergyPlus and see whether you could cut your top-up costs under the July–September 2026 cap.

Quick answer

Yes — you can usually change to a cheaper prepayment tariff in the UK, either by moving to a different tariff with your current supplier or by switching supplier on your existing key, card or smart PAYG meter. Since the Ofgem reforms, prepayment customers in Great Britain are no longer charged more than Direct Debit customers: the same price cap applies to both payment methods.

From 1 July 2026, the Ofgem cap sets typical prepayment and Direct Debit rates at around 26.11p/kWh for electricity (standing charge 57.19p/day) and 7.33p/kWh for gas (standing charge 29.04p/day). To pay less than the cap, look for a fixed prepayment deal at or below cap rates, switch to smart prepay for more tariff choice, and check whether moving to Direct Debit (where you’re eligible) would cut your bill further.

The fastest way to see your options is to compare whole-of-market tariffs for your postcode and meter type.

Compare cheaper prepayment tariffs (PAYG)

If you’re on a prepayment meter (key, card, or smart PAYG), you can often move to a cheaper prepayment tariff with your current supplier or by switching to a different supplier — depending on what’s available for your meter and area. EnergyPlus helps you compare whole-of-market options for home energy in Great Britain, so you can see how the deals on offer stack up against the July 2026 price cap.

Good to know before you compare

  • Prepayment is now capped at the Direct Debit level. The old prepayment premium has gone; both methods sit under the same Ofgem cap, currently confirmed to 30 September 2026.
  • Not all suppliers accept all prepayment customers. Some have extra checks, especially if there’s an outstanding balance on the meter.
  • Tariffs vary by region (your postcode matters), and prices differ between electricity and gas.
  • Smart prepayment typically offers more top-up options, better usage visibility and a wider choice of tariffs — but availability depends on your meter and supplier.

Prepayment vs Direct Debit under the July 2026 price cap

Ofgem confirmed the July–September 2026 (Q3) price cap on 27 May 2026, in effect from 1 July 2026. Crucially for PAYG households, the cap “levelises” standing charges across payment methods — so prepayment customers are no longer charged a premium for their daily standing charge. The headline unit rates below are the GB average; your exact rates depend on your region.

Cap element (1 Jul–30 Sep 2026) Electricity Gas
Unit rate (p/kWh) 26.11p 7.33p
Standing charge (p/day) 57.19p 29.04p
Applies to prepayment? Yes — same cap level as Direct Debit Yes — same cap level as Direct Debit

For context, the April–June 2026 cap was lower, at around 24.7p/kWh for electricity, so most households saw unit rates rise slightly from 1 July 2026. The cap is reviewed every three months; the October–December 2026 level has not yet been confirmed, so treat any “autumn” figures as forecasts rather than fact.

Standing-charge levelisation explained

Standing charges are the fixed daily cost you pay before using a single unit. Ofgem “levelised” these so prepayment customers pay broadly the same daily charge as Direct Debit customers, removing the historical PAYG premium. If most of your spend is the standing charge, a low-usage tariff or a switch to credit billing can make a bigger difference than the unit rate.

How to beat the cap on prepayment

The cap is a ceiling, not a target. In mid-2026, some suppliers offer fixed prepayment deals priced at or just below the cap unit rates. Smart prepay typically unlocks the widest choice. Compare available deals to see whether a fixed PAYG tariff would save you money against the July cap.

Why switching to a cheaper prepayment tariff can help

Prepayment customers historically faced fewer choices and a price premium, but the market has improved — especially with smart meters and the levelised cap. If you’re topping up more often than you’d like, switching tariff (or supplier) can reduce the amount you need to add to keep your home running.

Lower unit rates or standing charge

A cheaper tariff can mean a lower price per kWh, a lower daily standing charge, or a better balance of both — depending on how you use energy. A fixed PAYG deal can also lock in rates against future cap rises.

More convenient top-ups

Smart PAYG can allow app and online top-ups and clearer credit tracking. Most suppliers also offer emergency credit and “friendly credit” hours so your supply isn’t cut off overnight or at weekends.

Better control (without overpaying)

Prepayment helps budgeting, but not all PAYG tariffs are equal. Comparing options helps you keep control while avoiding unnecessary cost above the cap.

Tip: If you can’t find a cheaper prepayment tariff, it may still be worth asking about moving from prepayment to credit (Direct Debit) mode where you’re eligible. That’s separate from switching supplier and can depend on your payment history and circumstances — but with the cap now levelised, the saving usually comes from tariff choice rather than the payment method alone.

How to change to a cheaper prepayment tariff (UK steps)

Most prepayment switches follow the same journey as credit-meter switches, with a few extra checks. Here’s what typically happens when you compare and move to a cheaper PAYG tariff.

  1. Identify your meter and fuel: key/card prepay, or smart PAYG. If you’re unsure, your in-home display (smart) or top-up method usually gives it away.
  2. Compare whole-of-market options: tariff availability varies by postcode, payment method and meter type. Benchmark each deal against the July 2026 cap rates above.
  3. Check supplier requirements: some suppliers won’t take on certain types of debt, or may require you to repay via top-ups under an agreed rate.
  4. Start the switch: you’ll get an expected switch date and instructions for keeping the supply on during the changeover.
  5. Keep your supply topped up: ensure you have enough credit during the switch, especially over weekends or bank holidays.
  6. New top-up method: you may receive a new key/card, or instructions to top up via app/online/PayPoint depending on the supplier and meter.

Will I need a new meter?

Often no. You can usually switch on your existing prepayment meter. If you move to smart prepayment, a meter upgrade might be offered — many suppliers fit smart meters at no upfront cost — but it depends on your property and supplier rollout.

Will my supply be interrupted?

Switching supplier should not cut off your energy. The main risk is running out of credit mid-switch — keep an eye on your balance and use emergency credit if you need it.

Can I switch supplier on prepayment? Eligibility checklist

Many households can switch prepayment tariffs, but outcomes depend on meter type and supplier policy. Use this checklist to understand what might affect your options.

Outstanding balance / debt

Suppliers must let you switch with debt of up to £500 per fuel under the industry “Debt Assignment Protocol”, carrying the balance to the new supplier. Above that, you may need to repay first or agree a plan via your top-ups.

Meter type & compatibility

Key/card meters may have fewer tariff options than smart PAYG. Your supplier may need to issue a new key/card or update settings remotely.

Property & account details

Make sure the address and meter details match your account. If you’ve just moved in, you may need to register with the current supplier first.

If you’re struggling to top up

If you’re in financial difficulty, contact your supplier as early as possible. They may be able to review repayment rates, add emergency or additional support credit, or help you access schemes you’re eligible for. See the support for PAYG customers section below.

What makes a prepayment tariff “cheaper”?

When you compare PAYG tariffs, “cheaper” doesn’t always mean the lowest unit rate. Your total cost depends on how much energy you use and the tariff structure — and on how each deal compares to the July 2026 cap.

Price factor What it means for prepayment Who it often suits
Unit rate (p/kWh) How much you pay for each unit. Cap-level is 26.11p electricity / 7.33p gas from July 2026. Higher-usage homes, electric heating, larger families.
Standing charge (p/day) Daily fixed cost that applies even if you use little energy. Cap-level is 57.19p electricity / 29.04p gas. Low-usage homes may prioritise a lower standing charge.
Fixed vs variable A fixed prepayment deal locks rates for the term; a variable tariff tracks the quarterly cap. Anyone wanting price certainty against future cap changes.
Debt repayment rate If you owe money, a portion of each top-up may go towards repayments. Anyone with arrears should compare based on net top-up impact.
Top-up method & fees Most top-ups are fee-free, but convenience differs (shop, app, online). Households wanting easier payments may prefer smart PAYG.

Regional pricing (postcode)

Energy prices vary across Great Britain due to regional network costs. Two households on the same tariff name can still see different rates if they’re in different regions, so the cap figures above are GB averages.

Direct Debit vs prepayment

With standing charges now levelised, the two methods sit under the same cap. Direct Debit can still edge ahead on certain fixed deals, but if you’re staying on prepayment, comparing PAYG options is the most relevant route. See typical savings.

Support for prepayment (PAYG) customers

Prepayment customers have extra protections so a low balance never leaves you without heat or power. If a cheaper tariff isn’t available, these safeguards can still help you stay on supply and manage costs.

Emergency & friendly credit

Most meters offer emergency credit if you run low, plus “friendly credit” periods (typically overnight, at weekends and on bank holidays) so your supply isn’t disconnected when you can’t top up.

Priority Services Register

If you’re of pension age, disabled, have a long-term health condition or young children, ask your supplier to add you to the free Priority Services Register for extra support.

Hardship & debt help

Suppliers can offer additional support credit, hardship funds and affordable repayment rates. Charities such as Citizens Advice and StepChange also provide free, independent help.

Rules around forced prepayment installation were tightened across 2023–2024, with suppliers required to assess vulnerability before moving anyone to a prepayment meter and to offer support first. If you’ve been moved to PAYG and it isn’t right for you, you can ask to move back to credit billing where you’re eligible.

Common prepayment switching mistakes (and how to avoid them)

Comparing without checking meter type

Key, card and smart PAYG can have different tariff availability. If you’re unsure, choose “Not sure” in the form and we’ll help you narrow it down.

Forgetting to factor in debt repayment

If part of your top-up goes to debt, your day-to-day experience can feel “more expensive” even if the tariff rates are lower. Always check the repayment setting.

Running low during the switch window

Keep enough credit to cover the switch period. If you’re close to zero, top up before you start the switch and keep emergency credit available if your meter supports it.

Assuming prepayment is always more expensive

That used to be true, but the cap is now levelised across payment methods. Your best option depends on your usage, region, and what each supplier offers for your meter.

FAQs: cheaper prepayment tariffs in the UK (2026)

Yes. You can usually switch to a cheaper prepayment (PAYG) tariff, either with your current supplier or by switching supplier, provided your meter type is supported and any debt is handled. Since prepayment is now capped at the same level as Direct Debit, the best savings come from finding a fixed deal at or below the July 2026 cap rates (26.11p/kWh electricity, 7.33p/kWh gas). Compare options at /quote.

No. Ofgem levelised standing charges so prepayment customers in Great Britain are no longer charged a premium — both methods sit under the same price cap. Direct Debit can still win on some fixed deals, but the gap is far smaller than it used to be. Compare both to be sure.

For 1 July to 30 September 2026, the Ofgem cap (confirmed on 27 May 2026) sets typical rates at 26.11p/kWh for electricity with a 57.19p/day standing charge, and 7.33p/kWh for gas with a 29.04p/day standing charge. These cap levels apply to prepayment and Direct Debit alike; your exact rates vary by region.

Often yes. Under the industry Debt Assignment Protocol you can usually switch with debt of up to £500 per fuel, carrying the balance to your new supplier. Above that, you may need to reduce the debt first or agree a repayment plan via your top-ups. Submit the form with your meter type and we’ll guide you through what’s realistic.

Not automatically, but smart prepay usually opens up more tariff choice and convenience (app and online top-ups, usage data, remote updates). The cheapest choice still depends on supplier pricing in your area and your usage profile.

Yes. Your current supplier may offer multiple prepayment tariffs, including fixed deals. Comparing whole-of-market options also shows whether switching supplier could unlock a better price against the cap.

Your supply should stay on throughout. A switch typically takes from a few days up to a couple of weeks, and is often quicker on a smart meter. The key point is to keep enough credit on the meter during the changeover.

You’ll usually need to register with the existing supplier at the property first (even temporarily) and make sure the account is in your name. After that, you can compare and switch when you’re ready.
