Install solar panels or a heat pump through Octopus Energy and receive a £100 gift card — redeemable at Amazon, M&S, IKEA and more. Updated March 2026.
Octopus Energy's Smart Tech referral programme rewards new customers who install qualifying renewable technology with a £100 gift card. Here's everything you need to know.
Install a solar panel system through Octopus Energy and receive your £100 gift card once your installation is complete. Systems start from £6,163 and can save you up to 85% on electricity bills when paired with a battery and smart tariff.
Learn About Solar →Switch to an Octopus Cosy heat pump and claim your £100 gift card. With the £7,500 Boiler Upgrade Scheme grant, a heat pump could cost you as little as £500 after government support — and save you ~£465/year vs a gas boiler.
Learn About Heat Pumps →Your gift card is sent after your installation completes. Choose from a wide range of popular retailers including Amazon, M&S, IKEA, Air BnB, TK Maxx, Costa and many more. The perfect way to offset your installation costs.
