Octopus heat pump referral code: what to do first
There is no code to paste into a checkout. The £100 Octopus Smart Tech reward is connected to a referral link. Open the link before requesting a heat-pump quote, register the recipient's details, then use the same email address for the quote. A completed qualifying installation triggers a £100 digital gift voucher for both people [1].
The referral reward is separate from the Boiler Upgrade Scheme. It should not be treated as a substitute for the installer’s assessment, grant application or a property-specific installation 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].
Grant, suitability and quote basics
In England and Wales, the Boiler Upgrade Scheme currently provides £7,500 towards an air-to-water or ground-source heat pump. Eligible off-gas-grid homes replacing oil or LPG heating can receive an additional £1,500 until 31 March 2027. The installer applies on the homeowner's behalf and the approved grant should appear as an upfront discount on the quote [3] [4].
A heat-pump survey matters because it checks heat loss, emitter sizes, position of the outdoor unit, cylinder space, electrical work and whether any insulation or planning issues need attention. A system works best when it is designed around the building, not when a generic size is assumed. Most homes can be assessed, but the survey is where requirements and extra works become clear.
| Check | What to ask |
|---|---|
| Grant | Is the BUS discount shown separately and is the property eligible? |
| Design | What heat loss, radiator or cylinder changes are included? |
| Planning | Does the proposed position meet permitted-development and noise requirements? |
| Referral | Was the same email used for registration and quotation? |
Make the decision on the final scope
Check the total after the grant, not a headline price. Read the proposed equipment list, warranty, installation timetable and exclusions. Octopus says its heat-pump journey moves from an initial cost exploration through an in-home survey to a detailed design and installation plan [5]. The final agreement, not an early estimate, is the point to compare against alternatives.
Keep your referral registration confirmation until the installation is complete. That is the practical way to avoid losing track of the £100 reward while the design and grant process are under way.
Keep the final decision evidence-led
The final answer on suitability comes from the property assessment. It should show how the system is sized, where equipment will be placed and whether any radiator, insulation or electrical work is needed. Review that final scope alongside the grant treatment before you decide to proceed.
