Octopus Energy referral code for heat pump owners

If you've fitted a heat pump, your home runs on electricity for heating — which makes the tariff you're on, and the supplier behind it, matter far more than it does for a typical gas household. Switch to Octopus through a referral link and you'll pick up £50 credit on top of landing on a tariff actually designed for how a heat pump uses energy.

Why Octopus suits heat pump owners

Heat pump owners are exactly the customer Octopus has built for. Most suppliers treat a heat pump like any other appliance and leave you on a flat rate, but Octopus offers Cosy Octopus — a tariff shaped around the way heat pumps work, with cheaper "cosy" periods so you can heat your home and hot water when electricity costs least and ease off during expensive peaks. Octopus also designs and installs its own heat pumps and runs dedicated heat pump research, so the company genuinely understands the technology rather than bolting a tariff on as an afterthought. Add 100% renewable electricity (so your efficient, low-carbon heating is clean all the way to the grid), an app and support team people actually rate, a Which? Recommended record and an "Excellent" Trustpilot score, and you've got a supplier that fits a heat pump home far better than the big legacy names. The £50 referral credit is simply a bonus on top — paid automatically once you've switched, with no claiming and no catch.

• Cosy Octopus is purpose-built for heat pumps: it gives you cheaper "cosy" rate windows during the day (and overnight) so you can pre-heat your home and warm your hot water cylinder when electricity is cheapest, then coast through the pricier peak periods.
• Because a heat pump can be one of the biggest electricity users in your home, landing on the right time-of-use tariff makes a real difference — far more than it would for a gas-heated household. Octopus also lets you switch tariffs for free once you're a customer, so you can move onto Cosy (or trial Agile/Tracker) without being locked in.
• 100% renewable electricity means your low-carbon heating is genuinely low-carbon end to end — there's little sense pairing an efficient heat pump with grid power backed by fossil fuels.
• Octopus is heavily involved in the UK heat pump world (it manufactures and installs its own units and runs an R&D centre dedicated to them), so its tariffs, app and support are built by people who actually understand how heat pumps run — handy when you want help getting your settings dialled in.

The tariff tip

If you've got a heat pump, look at Cosy Octopus first — it's the tariff built specifically for them, with cheaper daytime and overnight "cosy" windows for heating your home and hot water. Compare it against Agile or Tracker for your usage pattern (rates vary by region, so check current prices on octopus.energy), and remember you can switch between Octopus tariffs for free once you've joined.
