From beginning to end service was excellent. My old system was very non-standard. This was not a problem for the Octopus team, who did the installation in a week, exactly as I wanted it. Theirs was the cheapest of three quotes I obtained. So three cheers for their efforts.

What's required to get the £7,500 Government BUS grant
To claim the BUS grant, you'll need to check off the following:
- You'll need to own your home.
- You'll need to have an EPC from the past 10 years. If you don't, no worries.
We can arrange that for you. - You'll need to check you have enough space for your new system. Check out our sizing guide here.
- If your home is undergoing renovation you'll need to wait until it's complete. In the meantime, here are some tips to help you on your way.
What is a heat pump?
A heat pump extracts heat from the air outside and brings it into the home using electricity. This means you get a bigger quantity of heat with less electrical power usage.
Air-source heat pumps give you comfortable, consistent heating and hot water. But with…
- Less energy: Heat pumps use up to 4x less energy than even the most efficient boilers to generate the same amount of heat.
- Less carbon: That efficiency means you’ll instantly slash your heat carbon footprint by around 80%. Plus, they run on electricity, which gets greener every year.
- Longer life: A heat pump can last 20 years – up to twice as long as a gas boiler.

How does a heat pump compare to a gas boiler?
From our research, we found homeowners with a heat pump are generally happier with their heating than those with a gas boiler.
We surveyed 2,300 customers to find out how satisfied they were with their heating system, including heat pump owners and gas boiler owners. The results showed that:
- 90% of heat pump owners were satisfied with how warm it kept their home, compared to 80% of gas boiler owners.
- Heat pump customers gave their heating system a 7 out of 10 rating in terms of cost-effectiveness, while gas boiler owners rated theirs at 6.
I’m planning on renovating my home or building an extension, can I still get a heat pump?
Making home improvements is really exciting, and a heat pump could be the icing on the cake! If you’re planning to make structural changes (like knocking down a wall or adding an extension), you will need to wait for the renovation to be complete before we can begin designing your heat pump.
This is because big changes will alter the overall heat loss and thermal performance of your property. We tailor your heat pump design specifically to your home, so if the layout changes, the needs of your heat pump will too. This means your heat pump may end up being too small or less efficient, and cost you more money in the long run. Your heat pump may also no longer meet MCS requirements, which is needed for the government grant.
However, there are some things you can factor into your renovation plans now to get your home heat pump ready:
- Underfloor heating/ radiators - underfloor heating is the perfect partner for heat pumps or larger, higher output radiators to accommodate the lower flow temp. Just let your contractor know you're planning to match it with a heat pump and they'll find the right emitters for you.
- Pipework - you'll need a minimum pipe size of 15mm for a conventional heat pump. If you have smaller pipes, they can still work well but you may need a more bespoke system.
- Space - think about where you'll be placing your heat pump (outside) and water cylinder (inside) - the closer together, the better!
- Insulation - renovation can be a prime time to add more insulation to your property, which will make your heating more efficient (whatever system you have)
Please get back in touch once your renovation is structurally complete and we'll be happy to give you a heat pump quote.
How much does a heat pump cost?
Our heat pumps start at £500 for a standard installation (including the £7,500 government grant). For larger or more complex homes, costs will be higher, but even with that in mind, almost all our quotes are lower than the national average of £5,565.
All we need is a few details to generate a tailored quote for your home. We’ll use the info you give, as well as your home’s energy performance certificate (EPC) from the national database, to calculate your fixed price.
We'll be able to let you know exactly what you need and how much it costs, including necessary additional works after your no obligation home survey. Find out more about potential additional costs in the Cost, grants and savings section.
Should I wait for the Cosy 6 heat pump?
In September we announced our new 'Cosy 6' heat pump- our super-smart, super-green new Octopus heat pump! We have now started to install our smallest model 'Cosy 6', alongside our current heat pump range. If you are interested please sign up as usual and we'll let you know which options are available to you once your survey is complete.
Do I need to be an Octopus Energy customer to get a heat pump installed with you?
