See which UK suppliers are offering switching credit

Some UK energy suppliers run limited-time promotions that add a bill credit (often up to £100) after you switch. These offers can be tariff-specific, may depend on direct debit, and often apply after your switch completes. The simplest way to find what’s currently open is to compare using your postcode and household details.

Whole-of-market comparison: EnergyPlus.co.uk compares home energy options across the market to help you spot eligible switching credit, while still prioritising the total cost of the tariff (not just the headline credit).

Important: a “£100 credit” headline doesn’t always mean you’re £100 better off overall. We’ll help you compare the full annual cost (rates + standing charge) and confirm when and how any credit is applied.

What does “£100 credit for switching” mean?

In the UK, switching credit typically means a supplier adds a bill credit to your account after you complete a switch. It’s not usually cash in your bank. The exact value may be a fixed amount (e.g. £100) or an equivalent promotion. Credit offers can be available for electricity-only, gas-only or dual fuel—and the terms can differ.

Bill credit (most common)

A credit is applied to your energy account, reducing future bills. Often added after your first bill, a set number of days, or once payments are taken.

New customer promotions

Limited-time offers to attract new customers. These can be capped by region, payment method, meter type, or tariff start date.

Equivalent incentives

Sometimes the headline is framed as “up to £100” or split across fuels. The real value depends on terms and how/when it’s applied.

Why people switch for credit (and how to make it worth it)

Switching credit can be useful, but the best outcome comes from comparing the total cost of the tariff. A slightly higher unit rate can wipe out the value of a £100 bill credit over the year. EnergyPlus helps you focus on the numbers that matter.

Lower overall annual cost

See estimated yearly costs including rates and standing charges, then weigh any credit against the total.

Clarity on credit terms

Understand when the credit is applied, whether it’s split across fuels, and what happens if you switch away early.

Support for home switching

If you’re unsure about meter types, payment methods or timing, we’ll help you compare the right options for your home.

How switching credit offers work (typical timeline)

Each supplier sets their own rules, but the process below reflects how many UK switching credit promotions are structured. Always check the tariff and offer terms before you apply.

  1. Compare and apply: choose a tariff that states it includes switching credit (where available) and complete the switch.
  2. Switch completes: the new supplier takes over your supply. You’ll typically provide an opening meter reading.
  3. Account set-up: direct debit is confirmed (if required) and your first bill or statement is produced.
  4. Credit applied: the credit is added to your energy account based on the offer rules (for example, after a set number of days or after an initial payment).
  5. Keep records: save the confirmation email and tariff details, and check your account around the expected date.

Tip: If two tariffs are similar, compare the standing charge carefully. Over a year, small differences can outweigh a one-off credit.

Eligibility: who can get £100 switching credit?

Eligibility varies by supplier and tariff. The points below cover common requirements for UK home energy switching credit promotions. If you’re not sure, use the form above and we’ll show what’s currently eligible for your home.

Common requirements

  • New customer to that supplier (sometimes not held an account in a set period)
  • Tariff must be applied for within the promotional window
  • Payment method restrictions (often monthly direct debit)
  • Credit is usually applied after the switch completes and/or first payment

Common exclusions

  • Business energy contracts (this page is home energy only)
  • Prepayment meters on specific tariffs (depends on supplier)
  • Switching to the same supplier (not a new acquisition)
  • Offer not valid alongside certain other promotions

Regional note: the tariffs and standing charges you can access can vary by region because of network costs. That’s why postcode-based comparison is essential when searching for switching credit.

How to compare £100 credit deals properly (avoid costly mistakes)

If you’re searching for “energy suppliers offering £100 credit for switching UK”, it’s easy to overvalue the incentive. Use this checklist to confirm you’re choosing a tariff that works for your household and budget.

1) Compare total annual cost

Look at estimated annual cost first, then subtract any eligible credit to see the net effect.

2) Check exit fees and term

Some fixed deals include exit fees. Ensure the credit doesn’t trap you in a pricier tariff.

3) Confirm how credit is applied

Is it split across fuels? Applied after first bill? Only with direct debit? Read the conditions.

4) Match to your meter & payment type

Smart, credit and prepayment meters can have different tariff availability.

5) Time your switch

If you’re in a fixed deal, check whether you can switch without fees near the end of your term.

6) Keep evidence

Save screenshots/emails showing the credit offer, tariff name and application date in case you need to query it.

FAQs: £100 energy switching credit (UK)

Is £100 switching credit guaranteed?

No. It’s only paid if you meet the supplier’s eligibility rules and complete the switch under the offer terms. Availability can change quickly.

Is the credit paid as cash or off my bill?

Most promotions are bill credit applied to your energy account, not a bank transfer. The tariff terms should confirm how it’s delivered.

How long does it take to receive the credit?

It varies by supplier. Some apply it after your first bill or once a direct debit has been collected; others specify a set number of days after supply starts.

Can I switch if I’m on a prepayment meter?

Often yes, but eligibility for specific credit promotions may be limited. The best approach is postcode-based comparison and checking tariff conditions.

Does dual fuel always get more credit?

Not always. Some offers are a single credit amount; others split credit between gas and electricity or apply only to certain combinations.

Will switching affect my supply?

Your gas and electricity supply stays on; only the billing supplier changes. A smooth switch still relies on accurate meter details and readings.
