Which energy suppliers offer new-customer switch credit?
A UK guide to switch bonuses (credit, gift cards and bill discounts): what’s available, who qualifies, and how to compare the real cost of a deal.
- See the most common types of switch credit and eligibility rules (payment method, meter type, region).
- Understand exclusions and pitfalls (exit fees, fixed-term rules, cashback timing, failed switches).
- Get a whole-of-market quote and check if a bonus is worth it versus the unit rates.
Bonuses change frequently and depend on your tariff, payment method and eligibility. Always check supplier terms before switching.
Fast answer: who offers new-customer switch credit?
In the UK, switch credit is usually offered as a limited-time promotion rather than a permanent feature of specific suppliers. That means the best approach is to compare your whole quote first (unit rates + standing charges), then treat any bonus as a secondary benefit.
Common bonus types you’ll see
- Bill credit (e.g., “£X credit” applied after your first bill or after Y days).
- Gift cards / vouchers (sent by email/post after eligibility checks).
- Cashback (often via a third-party cashback site; paid later).
- Discounted monthly payments for a set period (less common; check how it’s calculated).
Quick eligibility checks
- Payment method
- Many promos require Direct Debit (monthly). Pay-as-you-go/prepay is often excluded.
- Meter type
- Some deals exclude prepayment meters or complex meter setups (e.g., multiple meters).
- Property / region
- Most domestic tariffs cover Great Britain; Northern Ireland is a different market and often not included.
Key takeaway (what matters most)
A £50–£100 bonus can look great, but it may be outweighed by higher unit rates or a higher standing charge.
If you want, you can use EnergyPlus to check tariffs that currently include a sign-up incentive (where available) and see whether it beats the cheapest no-bonus option for your usage.
How new-customer switch credit typically works
Switch credit is usually a reward for taking out a specific tariff and staying on supply for a minimum period. The details vary by supplier and promotion, but the mechanics are often similar.
- You sign up to an eligible tariff (often fixed, sometimes variable) and choose the required payment method (commonly Direct Debit).
- Your switch completes (usually within around 5 working days under Ofgem’s switching rules, but some cases can take longer).
- You meet the ‘staying’ condition (e.g., 30/60/90 days on supply, or your first bill produced, or no missed payments).
- The bonus is applied or sent as a bill credit, voucher, or cashback. This can take weeks or months.
When a ‘good’ bonus isn’t actually good
- Higher unit rates can outweigh the bonus over 12 months.
- Exit fees on fixed tariffs can remove the benefit if you switch again.
- Cashback delays can make it hard to rely on the money for bills.
- Ineligible meter/payment can void the reward after you’ve already switched.

Compare switch credit: what to look for (beyond the headline)
Because offers change, the most reliable way to compare is to assess the value, certainty and conditions of the incentive alongside the tariff cost.
| Bonus type | Typical value range | How you receive it | Key eligibility checks | Good for… |
|---|---|---|---|---|
| Bill credit | Often £25–£100 (estimated) | Applied to your account after a trigger (e.g., first bill / X days) | Direct Debit, active supply, sometimes no missed payments | People who want a simple, predictable benefit |
| Gift card / voucher | Often £30–£120 (estimated) | Email/post after validation; sometimes third-party fulfilment | Time on supply, correct contact details, eligible tariff only | Those happy with non-cash rewards |
| Cashback (often third-party) | Often £20–£120 (estimated) | Paid later by the cashback provider (timing varies) | Tracking rules, cookie/device requirements, claim windows | Confident online users who can manage claim steps |
| Discounted payments | Varies widely | Lower payments/credit spread over a period | Can depend on usage estimates and billing schedule | Those who prefer steady monthly budgeting |
Decision checklist: is switch credit worth it for you?
- I’m eligible (tariff, payment method, meter type, “new customer” definition).
- I’ll stay long enough to trigger the reward (and I understand exit fees).
- My estimated annual cost is still competitive even if the bonus is delayed or not paid.
- I know how it’s paid (credit vs voucher vs cashback) and I’m comfortable with that.
- I have documentation (email confirmation, promo code, screenshots where relevant).
Who it suits / who it doesn’t
Often suits
- Direct Debit payers
- People happy to stay 3–12 months
- Homes with standard credit/smart meters
- Anyone comparing total annual cost, not just bonuses
Often doesn’t suit
- Those likely to move home soon
- Anyone needing prepay / pay-as-you-go
- People who frequently switch and want zero exit fees
- Anyone relying on cashback timing to cover bills
A simple way to compare two tariffs with different bonuses
Take each tariff’s estimated annual cost, then subtract the bonus value you expect to actually receive. If the “bonus tariff” is still higher, it may not be worth it.
Costs, exclusions and common pitfalls (UK-specific)
Switch incentives are real, but they’re also one of the most common sources of confusion. These are the issues we see most often when households try to claim switch credit.
Exit fees can wipe out the bonus
Many fixed tariffs have exit fees. If you might switch again (or move home), a “£75 credit” can quickly disappear if you pay a fee to leave early.
Eligibility is often narrower than the headline
Promos may exclude prepayment meters, require Direct Debit, or apply only to certain tariffs (for example, online-only fixed plans).
- “New customer” definition may include a lookback period.
- Some bonuses apply only to dual fuel, not single-fuel.
- Smart meter requirements can appear in the small print.
Timing: “up to X days” can be a long wait
Bill credits might be applied after your first bill, or after a minimum time on supply. Gift cards and cashback can take longer due to validation steps.
Scenario 1: Bonus tariff vs cheapest tariff (with assumptions)
Assumptions (illustrative): typical household on dual fuel, Direct Debit, Great Britain, no existing debt, switch completes normally.
| Option | Estimated annual cost | Bonus | Net (cost minus bonus) |
|---|---|---|---|
| Cheapest tariff (no bonus) | £1,620 | £0 | £1,620 |
| Tariff with £75 bill credit | £1,690 | £75 (if paid) | £1,615 |
In this example, the bonus just about makes the more expensive tariff competitive. If the credit is delayed or you’re ineligible, it becomes the pricier choice.
Scenario 2: Fixed tariff bonus vs exit fee risk
Assumptions (illustrative): you switch to a 12-month fixed tariff with a reward, then need to switch again after 6 months.
| Item | Amount (example) | What it means |
|---|---|---|
| Switch credit | £100 | Paid only if you meet the supplier conditions |
| Exit fees (dual fuel) | £60 electricity + £60 gas = £120 | Payable if you leave early (check tariff terms) |
| Net effect | -£20 | In this example, the fee outweighs the bonus |
This is why switch credit tends to work best when you’re comfortable staying for the required period and you’ve checked exit fees upfront.
FAQs
1) Is switch credit the same as a referral bonus?
Not always. Switch credit is usually a general sign-up incentive. Referral bonuses require a unique link or code and may have different eligibility rules and payout timings.
2) Can I get switch credit on a prepayment meter?
Sometimes, but it’s less common. Many promotions are limited to monthly Direct Debit tariffs. If you’re on a prepayment meter (including smart prepay), check the tariff and promo terms carefully before switching.
3) How long does it take to receive the credit or voucher?
It varies. Some suppliers apply bill credit after your first bill or after a minimum time on supply (e.g., 30–90 days). Vouchers/cashback can take longer due to validation. Always rely on your tariff cost first, not the bonus timing.
4) Can I switch again straight away after receiving a bonus?
You can usually switch again, but check two things: exit fees (common on fixed tariffs) and bonus clawback rules (some promotions require you to remain on supply for a minimum period).
5) Does the Energy Price Cap affect switch credit?
The Ofgem price cap limits what suppliers can charge customers on standard variable tariffs (based on typical usage), but it doesn’t guarantee the cheapest deal for you. Bonuses are separate promotional terms and can appear on fixed or variable tariffs.
6) Will I lose my Warm Home Discount if I switch?
The Warm Home Discount is administered by suppliers under government rules and eligibility can depend on your circumstances and supplier participation. If you receive support, check the latest guidance and consider contacting your current supplier before switching.
7) What if my switch fails or is delayed?
Delays can happen due to meter data issues, address mismatches, or complex setups. Keep confirmation emails and note the promo details. If a delay affects your reward, ask the supplier how they apply the promo in delayed-switch cases.
8) Do I need to give meter readings when switching?
Often yes (unless your smart meter sends readings reliably). Accurate readings help produce a correct final bill with your old supplier and start bill accuracy with the new one—important if the bonus requires your first bill to be generated.
