Energy tariffs with switching bonus credit (UK guide)
See how switching credit works, what it’s really worth after eligibility rules, and how to compare whole-of-market tariffs fairly for your home and meter.
- Understand cashback vs bill credit, and when you’ll actually receive it
- Check common exclusions (payment method, meter type, address history, debt)
- Compare bonus offers without losing sight of unit rates, standing charge and exit fees
Bonus credit varies by supplier, tariff and eligibility. Prices and offers change; always check the tariff information label and supplier terms before you switch.
Fast answer: are switching bonus credit tariffs worth it?
They can be, but only if the ongoing tariff cost is still competitive after you account for unit rates, standing charge, how/when the credit is paid, and eligibility rules. A £50–£200 switching credit looks attractive, but it may be outweighed by a higher standing charge or unit rate over 12 months.
What it usually is
A one-off bill credit (applied to your energy account) or cashback (paid to you) for new customers who switch and meet the terms.
When it can help most
If two tariffs are close on price, bonus credit can tip the balance—especially for low-to-medium usage households where small price differences matter less.
The biggest “gotcha”
Credit may be delayed (e.g., after your first Direct Debit or 90 days), and some offers exclude certain meters, regions, or customers who’ve been with that supplier recently.
How switching bonus credit works (UK)
“Switching bonus credit” is usually a promotional incentive for new domestic customers. Suppliers and comparison services may describe it differently, but the mechanics tend to fall into three types:
- 1) Bill credit (account credit)
- Applied to your energy account balance. You may see it on a bill/statement or in your online account. Often paid after a set time (e.g., 30–90 days) and sometimes after your first successful Direct Debit.
- 2) Cashback
- Paid to you (e.g., bank transfer, cheque, voucher). It may come from the supplier or a third party and can have its own claim/validation steps and timescales.
- 3) Referral or sign-up rewards
- Linked to a referral code or scheme. These can be good value, but eligibility rules can be strict (e.g., “new customer” definitions, one reward per household/address).
Typical eligibility checks (varies by supplier)
- Payment method: often Direct Debit only (monthly), not prepayment and sometimes not quarterly cash/cheque.
- Meter type: credit meters, smart meters, Economy 7, or prepay may be treated differently depending on the tariff.
- Address / customer history: “new customer” may mean you haven’t supplied with them in the last 12–24 months; some apply per household rather than per person.
- Fuel type: dual fuel vs electricity-only; the credit may differ for each.
- Region: standing charges and available tariffs vary by distribution region; some promos may be restricted.
- Account status: active supply, no blocking debt issues, and a successful switch completion.
Two realistic scenarios (with numbers)
These examples show why it’s risky to choose on bonus credit alone. Figures are illustrative estimates for comparison only.
Scenario A: Low usage flat (electricity-only)
Assumptions: 1,800 kWh/year electricity, single-rate meter, paying by monthly Direct Debit, no exit fees, same region for both tariffs.
- Tariff 1 (with £100 credit): estimated £680/year, credit paid after 60 days
- Tariff 2 (no credit): estimated £610/year
Estimated outcome: even after £100 credit, Tariff 1 is ~£580 “effective first-year” and Tariff 2 is £610. In this scenario, the credit makes Tariff 1 look better only if you qualify and receive it as expected.
Scenario B: Family home (dual fuel, higher usage)
Assumptions: 3,100 kWh/year electricity and 12,000 kWh/year gas, monthly Direct Debit, 12-month fixed, exit fees may apply, same region.
- Tariff 1 (with £150 credit): estimated £1,720/year, £75 exit fee per fuel
- Tariff 2 (no credit): estimated £1,600/year, no exit fees
Estimated outcome: Tariff 1 “effective first-year” is ~£1,570 if you receive the full credit. But if you need to leave early, up to £150 in exit fees could erase the benefit.

Compare switching credit offers the right way
Use this table to sanity-check any “bonus” tariff. The aim is to avoid paying more over the year just to receive a one-off credit.
| What to compare | Why it matters | What to look for | Common red flags |
|---|---|---|---|
| Estimated annual cost | Best single metric for comparing like-for-like (same usage, region, payment method). | A lower annual cost before incentives; then subtract any eligible credit as a separate step. | Headline credit used to distract from higher standing charges. |
| Unit rates (p/kWh) | Drives your cost the more energy you use. | Competitive rates for your meter (single-rate, Economy 7, smart time-of-use). | Very low credit paired with high unit rates on fixed usage assumptions. |
| Standing charge (p/day) | Affects everyone, especially low users. | A standing charge that makes sense relative to unit rates and your consumption. | High standing charges “paid back” with a one-off bonus. |
| Bonus credit terms | Determines if/when you get the benefit. | Clear timescale (e.g., “within 90 days”) and conditions you can meet. | “Up to” credit, unclear payout date, or complicated claim requirements. |
| Exit fees | Can wipe out the bonus if you need to leave early. | Low/none if you want flexibility; know whether fees apply per fuel. | High fees on fixed tariffs marketed with large incentives. |
Decision checklist: who switching credit often suits
- You can pay by monthly Direct Debit (often required for credit).
- You’re staying in the property long enough to meet payout timescales.
- You’ve checked you’re a new customer under the supplier’s definition.
- The tariff is still competitive on rates and standing charge without the bonus.
- You want a simple, one-off perk rather than a complex rewards scheme.
Who it may not suit (or needs extra checking)
- You’re on a prepayment meter (many credit offers exclude it).
- You might move soon, or may need to switch again before credit is paid.
- You’re switching from the same supplier group (some exclude “existing” customers).
- Your current tariff has exit fees that outweigh the bonus.
- You rely on exact budgeting and the credit would be delayed or uncertain.
Costs, exclusions and common pitfalls (UK)
Switching bonuses can be genuine value—but the terms matter. These are the most common reasons people don’t receive the credit, or end up worse off overall.
1) You don’t meet the “new customer” rule
Some suppliers define “new” by household, address, or supply history (e.g., not supplied by them in the last 12–24 months).
2) Payment method or meter type is excluded
Many offers require Direct Debit and may exclude prepay, some Economy 7 setups, or certain smart/time-of-use arrangements.
3) You switch again too soon
If the credit is paid after 60–90 days (or longer), leaving early may mean you forfeit it.
4) Exit fees erase the bonus
Fixed tariffs can charge exit fees per fuel. If you might move or re-switch, factor these in upfront.
5) “Up to” credit or split credit
Some offers are split (e.g., electricity + gas) or depend on completing both fuels. Check what applies if you’re electricity-only.
6) Budgeting surprises
Bill credit may reduce your balance but not your Direct Debit immediately. Suppliers can adjust payments based on usage and account balance.
FAQs
Are switching bonuses the same as cheaper unit rates?
No. Bonus credit is usually a one-off incentive. Unit rates and standing charges affect your bills every day. For most homes, the best approach is to choose the most suitable tariff first, then treat any bonus as an extra—only if you’ll qualify.
When do I actually receive the credit?
It depends on the supplier and offer. Common timings include after the first Direct Debit is taken, after the switch completes, or after a minimum period such as 60–90 days. Always check the specific terms on your tariff and any welcome communications.
Can I get switching credit if I’m on a prepayment meter?
Sometimes, but many bonus offers are limited to monthly Direct Debit credit meters. If you’re on prepay, focus first on tariffs available for your meter type. If you’re eligible and want to change meter/payment method, check with the supplier first as it can affect your options.
Do I lose the credit if I move house?
Potentially. Some offers are tied to the account at a specific address and require you to remain supplied for a minimum period. If you might move, prioritise tariffs with low/no exit fees and straightforward terms, and check how the supplier handles moves.
Is switching energy safe—will my supply be interrupted?
In the UK, switching supplier should not interrupt your physical energy supply. Your gas and electricity still come through the same pipes and wires. You’ll simply be billed by a different supplier once the switch completes.
Can switching credit affect my Direct Debit amount?
It might reduce your account balance, but your Direct Debit may not change immediately. Suppliers set Direct Debits based on expected annual usage and your account position. If you want a review, you can request one after your account is set up.
What if I’m on Economy 7 or a smart time-of-use tariff?
Not all bonus tariffs are available for multi-rate meters. Even when they are, the “best” tariff depends on how much electricity you use off-peak. Compare using the correct meter type and your realistic day/night split if applicable.
How do I check if a tariff has exit fees?
Look for exit fee details in your tariff information and contract summary. If you’re already in a fixed tariff, your current supplier should show any exit fees in your online account or on your latest statement.
Trust, editorial standards and transparency
How we assess switching bonus credit tariffs
Our editorial aim is to help you make a fair comparison. We treat switching credit as an incentive, not the main measure of value.
- Primary comparison metric: estimated annual cost based on unit rates and standing charges for your region, meter type and payment method.
- Incentives: assessed separately as a one-off adjustment, only when terms specify how/when it is paid.
- Eligibility focus: we highlight common conditions (e.g., Direct Debit requirement, “new customer” definitions, dual fuel requirements).
- Risk checks: we encourage you to consider exit fees, move likelihood, and whether the credit is delayed or “up to”.
Assumptions & limitations (important)
- Examples on this page are illustrative and not live quotes. Your prices depend on your postcode, meter type, usage, and payment method.
- Offers change frequently. Suppliers can amend or withdraw switching credits at short notice.
- Eligibility varies by supplier and sometimes by tariff. Always check the tariff’s contract summary and terms.
- Direct Debit changes: bill credit doesn’t guarantee your monthly payment reduces immediately.
UK sources we rely on
- Ofgem (Great Britain energy regulator) — guidance on switching, tariffs and consumer protections.
