Compare energy deals with cashback — and switch with confidence

Some UK energy suppliers (and switching routes such as partner promotions) offer cashback for switching. It’s typically a one-off payment after your switch completes and your account is live for a qualifying period. The key is comparing the total value: the unit rates and standing charge matter more than a headline cashback figure.

EnergyPlus.co.uk is a whole-of-market comparison service for home energy. Submit your details to see what’s available for your postcode, usage and meter type.

Quick tip: If two tariffs cost about the same over 12 months, cashback can be a bonus. If the tariff is more expensive, you may pay more overall even after cashback.

What you’ll need (takes 2 minutes)

  • Your postcode (to show local availability)
  • An email and phone number so we can help you progress your switch
  • If you have it: current supplier/tariff and recent usage (optional, but improves accuracy)

Which UK energy suppliers offer cashback for switching?

Cashback offers change frequently and can be available via different routes (e.g., supplier direct promotions, partner campaigns, or comparison-led incentives). Rather than relying on an out-of-date list, the best approach is to check live availability for your postcode and meter type.

When you compare through EnergyPlus, we highlight relevant incentives where available and help you understand the real cost of the tariff over time.

Supplier-led cashback

Sometimes a supplier runs a limited promotion for new customers. These may require switching via a specific channel and meeting eligibility criteria.

Partner incentives

Cashback may be offered through partners (for example, promotional campaigns). The tariff pricing still matters most—compare the full 12-month cost.

Bill credit vs cashback

Some offers are credited to your energy account (bill credit) rather than paid to your bank. We’ll help you identify what type of incentive it is.

Good to know: If a supplier withdraws an offer, it may disappear quickly. Checking live results is more reliable than searching for “cashback switching offers” lists.

Why switch with cashback (and what to watch out for)

Reduce the net cost

If the tariff is competitive, cashback can lower your effective annual cost. Always compare the unit rate and standing charge.

Switch without disruption

Switching supplier doesn’t change your pipes or wires, and your energy supply stays on. You’ll just get bills from your new supplier.

Avoid “cashback traps”

Some offers require you to stay on supply for a set period, keep direct debit active, or avoid changing tariff before cashback is paid.

Best for you if…

  • You’re happy to switch online and keep your details consistent
  • You want an extra incentive on top of good pricing
  • You can stay with the new supplier long enough to qualify

Be cautious if…

  • You may move home very soon
  • You plan to switch again immediately
  • Your current supplier has exit fees (check your terms)

How cashback switching offers work in the UK

Cashback is usually a reward for becoming a new customer. The exact rules vary by supplier and promotion, but most follow a familiar pattern.

  1. Compare tariffs and choose a deal that suits your home (gas, electricity, or dual fuel where available).
  2. Apply to switch with accurate personal details (name, address, email and contact number).
  3. Switch completes (often within days, depending on supplier and setup). You’ll receive your welcome pack/confirmation.
  4. Qualifying period begins (e.g., you must remain on supply, keep payments up to date, and not cancel).
  5. Cashback is paid (as bank transfer, voucher, or bill credit) once terms are met.

Cashback types you may see

Cash paid to you

A one-off payment after the qualifying period. You may need to confirm details or meet specific conditions.

Bill credit

A credit applied to your energy account (reducing future bills). Often appears after a set number of months.

Vouchers & rewards

Gift cards or partner rewards. Good value for some households, but compare against the tariff cost first.

Cashback eligibility: who typically qualifies?

Eligibility depends on the supplier and the specific promotion. Common requirements include:

Typical requirements

  • New customer to that supplier (or not held an account within a set time)
  • Residential address in Great Britain (availability varies by region)
  • Direct debit set up and kept active
  • Accurate details matching your energy account (name/address)
  • Minimum time on supply before cashback is issued

Common reasons cashback fails

  • Cancelling during the cooling-off or qualifying period
  • Switching away again before the required time has passed
  • Payment issues (missed direct debit, arrears, account on hold)
  • Duplicate applications or mismatched address details
  • Applying on a different route than the one tied to the offer

When do you receive cashback after switching?

Cashback is rarely immediate. It’s normally paid after your switch has completed and you’ve remained on supply for the required period. The table below shows typical timelines so you can plan realistically.

Stage What happens Typical timing
Application submitted You choose a tariff and provide your details to start the switch. Same day
Switch completes You become live with the new supplier. You’ll receive confirmation. Often within days
Qualifying period You stay on supply and keep payments active to meet terms. Usually weeks to a few months
Cashback issued Cash paid, bill credit applied, or voucher sent depending on the offer. After qualifying period + processing time
How to protect your cashback: Keep a record of the tariff name, the offer terms, and confirmation emails. Avoid changing tariff or cancelling until the incentive has been issued.

Common mistakes when chasing cashback energy deals

Choosing a pricey tariff

A higher standing charge or unit rate can outweigh cashback quickly. Compare the full expected cost, not just the incentive.

Incorrect details

Small mismatches (name formatting, flat numbers, moving dates) can cause delays. Use the same address format as your current supplier.

Switching too soon again

Many offers require you to remain on supply. Switching away early can invalidate cashback.

FAQs: cashback for switching energy suppliers

Is cashback guaranteed when I switch?
Cashback is subject to eligibility and the offer’s terms. You typically need to complete the switch and remain on supply for a qualifying period. If cashback is available for your chosen deal, we recommend saving the confirmation details for your records.
Will switching affect my gas/electricity supply?
No—your energy supply stays on during the switch. The change is administrative (billing and customer service move to the new supplier).
What’s the difference between cashback and bill credit?
Cashback is usually paid out (e.g., to your bank or as a voucher). Bill credit is applied to your new energy account to reduce future bills. The best choice depends on whether the tariff is cost-effective overall.
Can I get cashback if I have a smart meter?
Often yes, but it depends on the supplier and tariff. Some smart meters may operate in “dumb” mode after switching until fully interoperable. We’ll help you check what’s available based on your details.
Do I have to switch both gas and electricity to get cashback?
Not always. Some offers apply to electricity-only or gas-only switches, while others may favour dual fuel. Availability varies by supplier and region.
What if I’m in debt to my current supplier?
If you owe money, switching may be restricted depending on the debt amount and payment status. It’s best to resolve arrears or agree a repayment plan before attempting to switch.
Can I switch if I’m renting?
In many cases, yes—if you pay the energy bills and have responsibility for the account. If bills are included in rent or the landlord manages the supply, you may not be able to change supplier.
How do I maximise the chance of receiving cashback?
Use consistent personal details, avoid cancelling during the qualifying period, keep direct debit active, and don’t switch away again until cashback is issued. Keep confirmation emails and note the offer’s key terms.
