Step 1
Sign up directly with Fuse
Start your switch through the official Fuse Energy website or app. Fuse's current rules exclude referred customers who switch through a price-comparison website.
How to get the £100 Fuse Energy referral credit
Step 2
Use code MARK62998
Enter MARK62998 during sign-up while the referral campaign is live. Fuse says the referral code needs to be entered as part of sign-up.
Step 3
Pay your first full bill
Complete your switch and pay your first full month of energy supply by the bill due date. If all eligibility requirements are met, the £100 reward is applied as bill credit.
Who is eligible?
Fuse's published referral terms set several conditions. In particular, the person being referred must be a genuinely new Fuse customer and sign up with at least one eligible import electricity or gas supply.
- New Fuse Energy customer
- Signs up directly rather than via a comparison site
- Uses the referral code during the live campaign
- Has import electricity and/or gas supply
- Pays the first full month's bill by its due date
- Meets Fuse's complete current referral terms
Important: £100 is the current referral amount published by Fuse. Fuse reserves the right to amend or cancel its campaign, so check the official terms before committing to a switch.
What do you actually receive?
Under the current campaign, the referred customer receives £100 of credit and the referring customer receives £100 of credit. Fuse says the amount is the same whether the qualifying new customer takes import electricity, gas, or both.
The reward is energy bill credit rather than cash. Fuse applies it against subsequent energy charges until the credit has been used. Export-only supplies do not qualify as an eligible referred supply.
Check the tariff as well as the referral reward
A £100 referral credit can be attractive, but it should not be the only factor in choosing an energy supplier. Before switching, compare the tariff's unit rates, standing charges, payment method, contract terms and estimated annual cost using your own consumption.
The referral reward is a one-off benefit; your ongoing tariff costs can matter considerably more over time. Get a personalised quote from Fuse and compare the overall cost with your current supplier and other tariffs before deciding.
Fuse Energy referral code FAQs
What Fuse Energy referral code can I use?
You can use MARK62998 when making an eligible direct sign-up with Fuse Energy while its referral campaign is live.
How much is the Fuse Energy referral reward?
Fuse currently publishes a reward of £100 bill credit for the qualifying new customer and £100 bill credit for the referrer.
Can I use MARK62998 after I have already signed up?
Fuse says referral codes must be entered during sign-up and while the campaign is live. Enter the code during the onboarding process rather than assuming it can be added later.
Can I use a referral code if I switch through Uswitch or another comparison website?
Not under Fuse's current referral terms. The referred customer must not have switched through a price-comparison website. To participate in the referral campaign, sign up directly with Fuse.
When will I receive the £100 credit?
Eligibility includes paying the first full month of Fuse energy supply no later than the due date. Fuse then applies qualifying credit against subsequent bills.
Is the £100 paid into my bank account?
No. Fuse states that the reward is bill credit only. It is not refundable or redeemable for cash.
Do I get £200 if I switch both gas and electricity?
No. Fuse describes the £100 referral credit as a flat amount per referred customer, whether the qualifying customer has one eligible supply or both gas and import electricity.
Does an export-only electricity account qualify?
No. Fuse's current terms say export electricity supplies are not eligible supplies for the referral reward.
