Save on solar and heat pumps with cashback from your bank
Did you know you could get up to £2,000 cashback from your bank when you get a heat pump or solar and a battery?
If you’re a customer of Lloyds, Halifax, Santander and Virgin Money, read on.
If you’ve been thinking about getting solar panels or a heat pump to upgrade your home and cut your energy bills, but not sure if you can afford it, we’re here to help.
Here at Octopus we offer a range of monthly finance offers in order to help spread the cost of a heat pump, solar and battery, including 0% finance on solar.
And to help even further, many of the biggest banks and mortgage lenders are offering up to £2,000 cashback to eligible customers who install heat pumps, and £1,000 for solar and battery.
For example, if you’re an eligible Lloyds Bank or Halifax mortgage customer, you could claim up to up to £2,000 cashback and a free EPC for making an energy efficient home improvement, such as installing a heat pump. And, thanks to our partnership with Lloyds Banking Group, by choosing to get it installed with Octopus, you'll be eligible for £100 energy credit. (*Terms and Conditions apply. Offer may be withdrawn at any time.)
That means, with the addition of the government's boiler upgrade scheme taking an additional £7,500 off the cost, you could get a heat pump for less than a gas boiler!

Making green energy cheaper for everyone
Octopus are on a mission to decarbonise UK homes.
That’s why we’ve worked hard to bring down the cost of installing low carbon tech, like heat pumps, solar and battery, in homes across the UK, making it easier and more affordable to benefit. Here are some of the other ways we’re reducing the cost of installation:

Solar panels
- Pay monthly with 0% finance. This means you'll pay nothing upfront for your solar panels and pay them, back over 1, 2 or 3 years through our partnership with Zopa. Or over 5 or 7 years at a fixed interest rate of 9.9% APR.
- Cut your electricity bills by 90% on an import and export tariff. Octopus Flux is designed to give you the best rates for soaking up those sunny rays and selling them back to the grid in peak periods.

Heat pumps
- Get a heat pump installed from as little as £500, with the £7,500 government grant (we’ll apply for the grant on your behalf)
- Technology you can trust. We've become the first energy provider to make and install our own heat pump with easy controls and smart benefits.
- Affordable and accessible for all — 90% of our heat pump quotes beat the national average cost.
Once you’re heat pump is installed, you could save £264 a year on heating compared to a gas boiler with the Cosy Octopus heat pump tariff
