Claim £100 when you install Octopus Energy solar panels and battery storage using an official referral link. The reward lands after your installation completes – as a gift card or account credit – and there’s no code to enter manually. Octopus run the solar service through their renewables team and handle everything from survey to grid paperwork.
If you’re getting solar panels and a battery installed, this is one of the easiest extras you can claim before booking. Here’s exactly how the referral works, what’s included in an Octopus solar install, who’s eligible, and how to combine it with switching to an Octopus electricity tariff for compounding savings. Last updated: June 2026.
The Octopus solar referral is a £100 reward paid out when you book a solar panel and battery installation through Octopus Energy’s tech-referrals programme. It works the same way as the standard Octopus refer-a-friend scheme, but is run separately by Octopus’s renewables team – a different division from your energy supply.
There’s no ‘code’ to copy and paste. You start your enquiry by clicking an official referral link (like the one on this page) and the £100 reward is tracked automatically against your installation.
You can read more about how Octopus referrals work in our guide to whether the Octopus referral scheme is legit, and how long credits typically take in how long the £50 referral credit takes (timing for the solar credit is similar – a few weeks after installation).
Booking through Octopus is a complete bundled install, not just panels on a roof. A typical installation includes:
The £100 referral stacks on top of all of that. It doesn’t reduce the install quote you’re shown – it lands after install completes.

The solar referral is completely separate from the £50 energy-switch referral. If you’re not already an Octopus electricity customer you can:
That’s £150 total in referral credit, plus you’ll typically benefit from Octopus’s solar-friendly Outgoing tariff once your panels are exporting – which over the system’s lifetime is worth a lot more than the initial credit.
If you also have an electric vehicle, pairing solar with an EV tariff like Intelligent Octopus Go compounds the savings: cheap overnight charging plus daytime solar generation.
Yes. Octopus runs several independent referral schemes:
Each is a different referral programme with its own link, and they don’t conflict. A new Octopus customer installing solar could realistically claim both the £50 supply credit and the £100 solar reward – £150 total. (We’re upfront that we earn a referral reward when you use our links – see our How We Make Money page.)
An Octopus solar installation is available to UK homeowners who:
You do not need to be an existing Octopus Energy customer to claim the £100 solar referral – it’s a separate purchase from your energy supply. That said, pairing the solar install with switching to Octopus (and claiming the £50 supply credit too) is the strongest combined offer, and it lets you use the Octopus Outgoing tariff to get paid for exported electricity.
The Octopus solar referral code is one of the simplest extras to claim before installing solar: £100 reward on top of a fully bundled install from a reputable supplier, with battery storage, inverter, grid paperwork and MCS certification all included. There’s no code to remember – just start your enquiry through an official referral link and the credit tracks itself.
£100 paid as a gift card or account credit when you complete a solar panel installation booked through Octopus via an official referral link.
No. Octopus’s solar referral tracks the reward automatically when you start your enquiry through a referral link – there’s nothing to type in.
Yes. The solar installation is separate from your energy supply. You can claim the £100 even if your electricity is with another supplier.
Yes. They’re two independent referral schemes – one for installing solar, one for switching your energy supply – so you can claim both if you’re doing both.
Octopus typically apply the credit within a few weeks of installation completion. If yours hasn’t arrived after 8 weeks, contact Octopus support with your installation date.
No. The system detects that the referrer and referee are the same person and won’t credit either side.
