Octopus solar referral code: the short answer
The referral offer is not a typed promotional code. It is a tracked sign-up journey: use an existing referrer's Octopus Smart Tech link before requesting a solar quote, register your contact details, and use the same email for the quote. If a qualifying solar installation completes, both the recipient and referrer receive a £100 digital gift voucher [1].
This page is for homeowners comparing an Octopus solar quote. It explains the referral step, the main choices that affect a solar proposal, and the questions worth resolving before you commit. It does not replace a property-specific design or quote.
How to keep the £100 referral on track
For a solar or heat-pump installation, the recipient and referrer each receive a £100 digital gift voucher after the installation has completed. The sequence matters: the recipient needs to use the referral link, sign up, and then obtain their quote using the same email address. Octopus states that it cannot add a referral retrospectively if the quote or purchase happened first [1].
- Register first: open the official referral page and submit the recipient's details.
- Keep one email address: use that same address for the Octopus quote and all follow-up.
- Review the design: the quote and survey determine whether the home and proposed system qualify.
- Wait for completion: vouchers are processed once the qualifying installation is finished [1].
Register before requesting a quote
That is the single rule most likely to protect eligibility. A referral link alone does not guarantee an installation, but quoting before registering can prevent the reward being applied [1].
What an Octopus solar quote should answer
A useful solar proposal is more than a panel count. Ask how the design reflects roof size, orientation, shading, household daytime consumption, export arrangements and any future plans for an electric vehicle or heat pump. Octopus says its solar packages use approximately 455W panels and provides hardware options including panel-only and solar-plus-battery systems [2].
Battery capacity changes how much generation you can use later in the day. It can be useful for households with evening demand, but it increases the upfront price. A smaller system that fits your pattern can be more sensible than buying capacity simply because it is available. Your quote should set out the equipment, warranties, scaffolding, electrical work, installation scope and any exclusions in plain language.
| Question | Why it matters |
|---|---|
| Panel-only or battery? | Determines how much solar can be used after sunset. |
| How many panels fit the roof? | Sets likely generation and system price. |
| What is included? | Clarifies equipment, installation work and exclusions before approval. |
| Can I use a smart tariff? | Helps you evaluate import and export options after installation. |
Before you accept
Confirm that the referral is attached, the installation address and email are correct, and the quote describes the agreed configuration. The current VAT relief for qualifying energy-saving materials runs to 31 March 2027, subject to the applicable rules; the installer should show how VAT is treated on the quotation. Solar payback is household-specific, so treat any savings figure as an estimate rather than a promise.
Once you are happy with the scope and timetable, keep the referral confirmation and quote together. That gives you a simple audit trail if you need to check the voucher after installation.
Keep the final decision evidence-led
A solar quote should be treated as a design proposal, not a guarantee of output or savings. Weather, shading, roof layout, electricity consumption and tariff choices all affect the result. The useful decision is whether the written configuration meets your needs at a price you understand, with the referral recorded separately.
