My Fuse Energy referral code gets you £100 off (and me £100 too)

I'll save you the suspense, because that's the deal and there's no reason to bury it: if you're switching to Fuse Energy and you use my referral code, Fuse puts £100 of credit on your account - and £100 on mine. That's how their refer-a-friend campaign works: both sides get the same amount. I'd rather tell you that plainly than pretend this page exists out of generosity.

Why I switched, briefly

I moved my supply to Fuse for the tariff and the app, and stayed because the switch was painless. This page isn't a review, though - it's here for one reason: if you've already decided to join Fuse, you might as well join with a code and take the £100.

How to use the code

Sign up directly at fuseenergy.com/app/boarding. Do not go through a price comparison website - Fuse's terms exclude comparison-site switches from the referral reward.
Put your postcode in first so Fuse can quote for your home.
Near the end of signup there's a referral code box. Enter QPNCKW19454.
Make sure the £100 referral offer shows before you confirm.
Pay your first full month's bill on time. After that, the £100 lands on your account (and mine).

The small print, in plain words

The reward is credit on your Fuse account, not cash. It comes off future bills and can't be withdrawn.
It's £100 whether you take one fuel or two - no difference.
It's for new customers signing up directly, one code per signup.
The end date - 15 November 2026 - is what the Fuse app shows. Fuse doesn't publish it on the website, and its terms say it can change or cancel the campaign whenever it likes. Check the app on the day you sign up.

What I checked before publishing this

On 21 October 2026 I checked this page's claims against Fuse's own sources: the Fuse referral blog, which states "The current reward is £100 per customer referred, regardless of how many fuels", and the promotions and referrals terms (last updated by Fuse on 10 August 2026), which set out the £100-each credit and the comparison-site exclusion.

What I can't check: whether Fuse's signup accepts the code on a given day - only Fuse's own flow can confirm that. The stamp above is the date of that check; this page is a static snapshot of what was true then.

Questions people ask

What's the catch?

There isn't one beyond the terms above. Fuse budgets for referrals instead of advertising; both sides get £100 of bill credit.

How long is the code valid?

The Fuse app shows the campaign running until 15 November 2026 (checked 21 October 2026). Fuse can end it earlier.

Is the £100 cash?

No - account credit, off future bills. Same for one fuel or two.

Is the Fuse Energy refer-a-friend offer worth it?

For me, yes. It was free £100 of credit on a switch I had already decided to make. It is credit on the energy account, not cash, so it only has real value if you were switching anyway. Check the app on the day you sign up - Fuse can change or end the offer.
