How the referral journey works
Check the underlying tariff first. Treat the referral credit as a bonus, not a substitute for comparing the full cost.

Fuse referral FAQs
Clear answers to the most important questions before you start a quote.
What Fuse Energy referral code should I use?
Use RCZCOL81649 if the referral campaign is available and you meet Fuse Energy’s current eligibility requirements.
Is the £100 bill credit guaranteed?
No. The credit is subject to Fuse Energy’s campaign terms and eligibility. Check the current official terms before switching.
Why do you ask for my postcode?

Is Fuse definitely cheaper than my current supplier?
No. Tariffs vary by address, usage, meter and payment method. Compare the full annual cost, unit rates, standing charges and terms before switching.
Is this the official Fuse Energy website?
No. This is an independent referral-information website. Quote buttons take you to the official Fuse Energy quote journey.
