Energy supplier switching bonus deals in the UK this month
See what “switching bonuses” usually look like right now (bill credit, cashback, gift cards), who qualifies, and how to compare the total cost of the tariff—without getting tripped up by small print.
- How to judge whether a bonus is worth it (with a quick value-check method)
- Common eligibility rules: meter type, payment method, new-customer status and time limits
- Two realistic examples with numbers (and when not to switch)
Bonuses and tariffs change frequently. Always check supplier terms, eligibility and exit fees. Quotes are estimates based on the details you provide.
Fast answer: are switching bonus deals worth it?
They can be worth it—but only when the total cost of the tariff (unit rates + standing charges + any fees) still stacks up after you account for the bonus and the payout rules.
Typical bonus types
- Bill credit after a set time (e.g. 30–90 days)
- Cashback (sometimes via a third party)
- Gift cards (limited retailers, expiry possible)
Quick value-check
A simple test: Bonus value ÷ months you must stay = “bonus per month”. If the tariff costs more than that vs alternatives, the bonus may not be worth it.
Biggest gotchas
- Bonus only for new customers
- Must pay by Direct Debit
- Bonus paid after a minimum supply period
Important: EnergyPlus is whole-of-market comparison for UK homes. We can help you compare tariffs and spot bonus terms, but we can’t promise a specific bonus will be available or paid—eligibility is set by the supplier and can change quickly.
Compare switching bonuses and tariffs (without the guesswork)
A switching bonus only matters if the tariff is still competitive for your home and meter. Use the form to get an estimated quote and see what’s available for your postcode, payment method and meter setup.
What you’ll need
- Postcode and address
- Whether you pay by Direct Debit, prepay or on receipt of bill
- Smart meter (if you have one) and whether you’re Economy 7
What we’ll show
- Estimated annual cost and key tariff features
- Any advertised bonus and the main conditions
- Notes on likely exclusions (e.g. prepay, certain meters)
Tip for accuracy: If you have a recent bill, your annual kWh usage (electricity and gas) improves estimates. If not, we can still provide a comparison using typical consumption assumptions.

How energy switching bonuses work (UK rules and reality)
In the UK, “switching bonuses” are usually marketing incentives offered by suppliers to attract new household customers. The key is that the bonus is rarely instant and often has conditions.
Common eligibility conditions
- New customer only
- Often excludes existing customers, and may exclude anyone who has held an account with the supplier within a set period.
- Payment method
- Many bonuses require monthly Direct Debit. Prepayment (PAYG) tariffs can have fewer incentives available.
- Meter type
- Some deals are restricted by smart meter status, Economy 7/10, or single-rate meters.
- Time on supply
- Bonuses may be paid after 30–120 days (or after the first successful Direct Debit) and can be forfeited if you switch away too soon.
What “bonus value” really means
- Bill credit: can reduce your balance, but may not be paid if your account closes before the credit date.
- Cashback: sometimes tracked via a third party; ensure your application journey matches the terms and keep confirmation emails.
- Gift cards: check retailer list, expiry, and whether it’s per account (dual fuel) or per fuel.
- Referral bonuses: may require a referrer link and are often limited to a certain number of referrals per year.
Editorial rule of thumb: treat any bonus as a one-off and compare the tariff as if you might not receive it. If the tariff only looks good because of the bonus, it’s higher risk.
Scenario 1: bonus helps, but only just
Assumptions (illustrative): GB home, dual fuel, pays by Direct Debit, no exit fees on current deal. Supplier A offers a £50 bill credit after 60 days.
- Tariff A estimated annual cost: £1,590
- Tariff B (no bonus) estimated annual cost: £1,565
- Difference: £25 more expensive for Tariff A
- After bonus: Tariff A is £25 cheaper in year 1 (if you qualify and stay long enough)
If you might move home, change payment method, or switch again quickly, Tariff B could be the safer option.
Scenario 2: “big” bonus, but tariff costs more
Assumptions (illustrative): fixed tariff with exit fees. Supplier C advertises £100 cashback paid after 90 days.
- Tariff C estimated annual cost: £1,720 (exit fee: £75 per fuel)
- Tariff D estimated annual cost: £1,610 (exit fee: £0)
- Difference: £110 more expensive for Tariff C
- After bonus: still £10 more expensive in year 1—and you take on exit-fee risk
If you switch again before the fixed term ends, exit fees could outweigh the bonus by a wide margin.
About the numbers: These examples are for illustration only. Your actual costs depend on your rates, standing charges, usage, region and payment method.
Compare bonus deals: what to check (and what to ignore)
Use the table to sanity-check an advertised incentive. The aim is to compare like-for-like: total estimated cost first, bonus second.
| Bonus type | Typical condition | Best for | Watch-outs |
|---|---|---|---|
| Bill credit | Credited after X days / successful Direct Debit | Those likely to stay on supply for several months | Can be lost if you switch away early; may apply per account not per fuel |
| Cashback | Often via tracked journey / third party | Organised switchers who keep confirmation emails | Tracking issues; payout delays; exclusions if you change details mid-journey |
| Gift card | Delivered after X days; retailer list applies | If you’ll genuinely use that retailer | Expiry dates; partial use; not cash; value can be less “real” than stated |
| Referral credit | Requires referrer link; limits may apply | Households with friends/family also switching | Not always compatible with other offers; can be withdrawn without notice |
Decision checklist: who bonus deals suit
- You can pay by monthly Direct Debit and keep it stable
- You expect to stay in the property for the bonus payout window
- You’re comparing unit rates and standing charges, not just the headline incentive
- You’re comfortable with a one-off reward that may have conditions
Who it may not suit
- You’re on prepayment and can’t (or don’t want to) change
- You might switch again soon (e.g. chasing a tracker) and risk missing payout
- You’re on a fixed deal with exit fees and are unsure you’ll stay for the full term
- You need certainty—bonuses can be changed or withdrawn by the supplier
Quick action: If two tariffs are similarly priced, a bonus can be a tie-breaker. If one tariff is materially cheaper on rates, it usually wins over time.
Costs, exclusions and common switching pitfalls (UK)
Most “bad surprises” come from timing, eligibility or fees. These are the checks we recommend before you switch for a bonus.
Exit fees
Fixed tariffs can charge exit fees per fuel. If you switch again before the end date, the fee can outweigh any bonus.
Check: your current tariff end date and exit fee amount before starting a switch.
Payment method changes
If the bonus requires Direct Debit and your payment method changes (even temporarily), you may become ineligible.
Check: whether “monthly Direct Debit” is required throughout the qualifying period.
Meter & tariff compatibility
Economy 7, smart meters and prepayment meters can limit which tariffs (and bonuses) you can take.
Check: whether the deal is single-rate only, or if Economy 7/10 is supported.
Timing: you can’t usually “stack” offers
Some suppliers don’t allow multiple incentives at once (e.g. cashback + referral), or they restrict a bonus to a single application route.
- Stick to one clear journey from quote to application
- Save screenshots/emails showing the offer and date
Moving home during the qualifying period
If you move, the supplier may open a new account at your new address and the original bonus may not carry over.
If you expect to move soon: prioritise no-exit-fee tariffs and treat bonuses as a “nice-to-have”, not the main reason to switch.
Reminder: Under Ofgem’s switching rules, suppliers and networks manage the switch process, and you should keep paying your current supplier until your switch completes and you receive a final bill.
FAQs
1) What counts as a “switching bonus” for energy in the UK?
Usually a one-off incentive for new household customers—most often bill credit, cashback, or a gift card—paid after you’ve been on supply for a set period and met the supplier’s conditions.
2) Do I still get the bonus if I only switch electricity (not gas)?
It depends on the offer. Some bonuses are per account (so dual fuel or single fuel), while others are specifically for dual fuel. Always check the offer wording and whether it’s “per fuel” or “per account”.
3) Can prepayment (PAYG) customers get switching bonuses?
Sometimes, but there are often fewer bonus deals available for prepayment tariffs. Many incentives require monthly Direct Debit. If you’re on prepay, compare based on the tariff first and treat any bonus as secondary.
4) How long does a UK energy switch take?
Switching time can vary. You’ll usually receive updates from your new supplier. Keep paying your current supplier until the switch completes and you receive a final bill.
5) Will switching affect my credit score?
Some suppliers may run credit checks for Direct Debit tariffs. If you’re concerned, check the supplier’s sign-up process. If you’re declined for credit reasons, you may still be offered an alternative payment option.
6) What if I don’t receive the bonus after switching?
First, check the terms for the payout date and conditions (e.g. minimum time on supply, Direct Debit requirement). If you believe you met the criteria, contact the supplier with your account details and any confirmation emails. If you’re still unhappy, you can follow the supplier’s complaints process.
7) Should I switch for a bonus if I’m already on a cheap fix?
Not automatically. If you’d pay exit fees, or your current unit rates are significantly lower, a one-off bonus may not compensate. Compare the estimated annual cost and add any likely exit fees before deciding.
8) Are bonus deals available everywhere in Great Britain?
Availability can vary by region, meter type and payment method. Some tariffs and offers are limited by supplier coverage and product rules. Entering your postcode is the quickest way to see what’s available for your home.
If your situation is complex: Economy 7, multi-rate meters, smart tariffs, or recent supplier-of-last-resort moves can change what you can switch to. We’ll flag likely restrictions in your quote results.

Our methodology (transparent and practical)
When we talk about “bonus deals this month”, we focus on how UK incentives typically work and how to compare them safely. We assess a bonus by looking at:
- Total estimated cost of the tariff (unit rates + standing charges) for a given usage profile
- Bonus certainty: how clear the eligibility rules are and how long you must stay on supply
- Restrictions: payment method, smart meter requirements, Economy 7 compatibility, new customer definitions
- Risk factors: exit fees, payout delays, third-party tracking, moving home
Assumptions and limitations
- All costs are estimates and depend on your region, meter type, payment method and usage.
- Bonuses can be withdrawn or amended by suppliers; eligibility is determined by the supplier at application and payout.
- We do not assume a bonus will be paid unless the terms are met; we encourage users to compare tariffs on price first.
- Switch timing and completion can vary; always wait for confirmation and a final bill from your current supplier.
