Find January 2026 sign-up credit deals for your home

Energy supplier sign-up credit (sometimes called bill credit, joining credit or welcome credit) can reduce your first bills after you switch. In January 2026, incentives can vary by region, payment method (e.g. monthly Direct Debit) and whether you’re switching to a fixed or variable tariff.

Use the form to request a comparison. We’ll check whole-of-market options and flag suppliers/tariffs where sign-up credit is likely to apply, alongside total cost and key tariff terms.

Tip: A headline “£X credit” isn’t always the cheapest overall. Compare unit rates, standing charges and exit fees alongside incentives.

Why supplier sign-up credit can be valuable (and when it isn’t)

Lower first bills

Joining credit is usually applied to your account balance after the switch completes. That can offset winter usage, catch-up payments, or your first Direct Debit review.

Better value if unit rates are competitive

A smaller credit on a cheaper tariff can beat a bigger credit on a higher unit rate. Comparing total cost over 12 months keeps the decision grounded.

Useful for switchers who can meet eligibility

Incentives may require monthly Direct Debit, online billing, and account set-up within a time window. We’ll help you check the typical conditions before you proceed.

When credit might not be worth it: if the tariff has high standing charges, restrictive terms, or exit fees that outweigh the incentive—especially if you expect to switch again soon.

How energy sign-up credit deals work in the UK

Energy sign-up credit is an incentive some suppliers use to encourage new customers to join. In practice, it’s rarely “cash in your bank” — it’s usually a credit applied to your energy account after your switch goes live or after your first bill. Terms vary by supplier and tariff, and can change during January 2026.

What “whole-of-market” comparison means

EnergyPlus compares tariffs across a broad range of suppliers and tariff types for UK homes. When incentives are available, we highlight them alongside the pricing and key terms so you can weigh up total value, not just the headline credit.

Why your postcode matters

Energy prices can vary by regional network area. Your postcode helps us show accurate rates and check if a supplier/tariff is available where you live.

What you’ll need to compare accurately

  • Your postcode and whether you want gas, electricity or dual fuel
  • How you pay now (e.g. monthly Direct Debit, on receipt of bill, prepayment)
  • Your typical usage (kWh) or a recent bill (helpful but not required to start)
  • Any preferences like fixed term, green tariffs, or no exit fees

Common incentive types you may see in January 2026

Suppliers describe incentives in different ways. This table explains the most common sign-up credit styles, typical conditions, and when they’re applied.

Incentive wording What it usually means Typical eligibility When you may receive it
Bill credit / account credit A credit added to your energy account balance (reduces what you owe). Often monthly Direct Debit, online account, new customers only. After switch completes or after first bill.
Welcome bonus A promotional credit or reward for joining a specific tariff. May exclude existing customers; may require a minimum term. Commonly within the first 1–3 billing cycles.
Dual fuel credit Credit offered when you take both gas and electricity with the same supplier. Must switch both fuels (where available); property must have gas supply. After both supplies are live / billed.
Referral credit A credit triggered by using a referral link/code (you and/or the referrer benefit). Requires valid referral at sign-up; may exclude some tariffs. Often after a set period or billing milestone.
Gift card / non-cash reward A voucher or reward instead of account credit. May have minimum term; may require online sign-up and no cancellation. Sometimes 30–90 days after supply start.

Important: Incentives can be withdrawn or changed at short notice. Always check final tariff terms before confirming a switch. If you request a comparison, we’ll explain what’s known about incentive timing and conditions for the options you’re considering.

Switching steps: how to maximise your chance of receiving the credit

  1. Compare like-for-like: review unit rates, standing charges, tariff length, exit fees and any sign-up credit.
  2. Check eligibility: confirm payment method requirements (often monthly Direct Debit), online billing, and “new customer” definitions.
  3. Sign up with accurate details: name and address must match your existing supply records to avoid delays.
  4. Keep records: save confirmation emails and note the advertised credit amount and conditions on the day you applied.
  5. Submit opening meter readings if requested: this helps ensure final and first bills are accurate.
  6. Watch the first bills: credit may appear as a line item or adjustment; it can take one or more billing cycles.

If you’re on a prepayment meter

Some incentives are limited to credit meters and Direct Debit tariffs. We can still compare available options, but sign-up credit may be less common. Tell us your postcode and we’ll show what’s realistically available.

If you have (or want) a smart meter

Some tariffs are smart-meter-only, while others work with traditional meters. Incentives can be linked to specific tariff types, so it’s worth noting your meter type during comparison.

Common mistakes when chasing sign-up credit (and how to avoid them)

Focusing on the headline credit only

A £50–£100 credit can be outweighed by higher standing charges or unit rates. Compare projected annual cost with and without incentives.

Missing the eligibility fine print

Credits can require monthly Direct Debit, e-billing, or specific tariffs only. If you can’t meet the conditions, the credit may not be applied.

Switching too quickly after joining

Leaving before the credit is due (or breaching minimum terms) can mean you don’t receive it—or you could face exit fees on some fixed deals.

Practical check: if two deals look similar, favour the one with clearer terms, lower ongoing rates, and fewer restrictions—then treat any sign-up credit as a bonus rather than the main reason to switch.

Eligibility checklist for UK sign-up credit deals

While every supplier’s terms differ, January 2026 sign-up credits commonly hinge on the factors below. If you’re unsure, submit the form above and we’ll help you interpret likely eligibility for your situation.

Often required

  • New customer to that supplier (definitions vary)
  • Monthly Direct Debit payment method
  • Online account and paperless billing
  • Account stays active through a minimum period

Sometimes required

  • Dual fuel switch (gas + electricity)
  • Smart meter or smart-meter readings
  • Specific tariff family or fixed term length
  • Registration within a promotional window

If you’re switching because your fix has ended, you may also want to compare standard variable tariffs vs new fixed deals and factor in how quickly an incentive would actually benefit you.

FAQs: energy supplier sign-up credit deals (UK)

Is sign-up credit guaranteed?

No. It depends on the tariff’s terms, eligibility, and whether the supplier is running the promotion at the time you apply. Credit is usually applied only once the switch is completed and conditions are met.

How long does it take to receive joining credit?

Often within the first 1–3 billing cycles after your supply start date, but it varies. Some incentives are credited after your first bill; others require your account to be active for longer.

Can I get sign-up credit if I’m already with the supplier?

Usually incentives are for new customers only, but definitions differ (for example, not having held an account with the supplier for a set period). We’ll help you sense-check eligibility when comparing.

Do I need to switch both gas and electricity to get the credit?

Not always. Some promotions apply to single-fuel switches, while others are specifically dual-fuel incentives. It depends on the tariff and supplier terms.

Will switching interrupt my supply?

No—your gas and electricity supply continues as normal. The switch is administrative, and you won’t typically experience downtime.

Is sign-up credit taxable or means-tested?

For most households, bill credit is applied to your energy account rather than paid as income. If you have a specific financial situation, check the supplier’s terms and consider seeking independent advice.
