Octopus Energy Heat Pump Installation.

A grant of £5000 is now available for homeowners wanting to switch their gas boiler to a brand new air-source heat pump. Register your interest now for an Octopus heat pump.

Speaking in the House of Commons earlier this year, Energy Minister Greg Hands said: “Octopus Energy, and indeed others, have said that they think they can make heat pumps an equivalent cost to natural gas boilers by April 2022.

“I’ve got confidence in the ability of British industry and energy companies.”

Fast Forward to 14th September 2023 – The Octopus Cosy 6 Heat Pump.

Octopus launched their own heat pump. 

This week I attended the Octopus Energy Tech Summit when Octopus unveiled the Octopus Cosy 6. A heat pump designed in Ireland and set to shake up the heat pump market even further.

OCTOPUS HAS LAUNCHED ITS OWN HEAT PUMP. FOR SOME PEOPLE THIS COULD BE INSTALLED FOR FREE! (Watch the video above)

How can I get an Octopus Energy Heat Pump?

You can now apply to replace your boiler with an Octopus heat pump. ⬅︎

What do I have to do to qualify for an Octopus heat pump?

Octopus has to survey your home to make sure it’s suitable for a heat pump.

Octopus will visit your home and look at your;

  • Rooms.
  • Roof space.
  • Fuse box.
  • Boiler,
  • Hot water tank (if you have one) or space where you could have a hot water tank.
  • Outside space where the heat pump will go.

The survey will take 2 – 3 hours to complete.

They will need to ask you some questions about your hot water usage and measure all your radiators. An important part of the survey is finding out if what you have is up to the job. You may need to add some insulation or change a radiator or two.  Each home is different, that’s why the survey is so important.

The heat pump survey covers everything. Octopus will work out where all the wiring will go and where additional equipment like a hot water tank can be housed if you don’t already have one.

Outside they will find the best spot for the heat pump. They can even show you what the heat pump will look like outside. They’ll simply add the heat pump to a photograph and bingo you’ll see it on their tablet. It’ll give you a better idea of what to expect.

Within a few days, you will be sent an overview of your new heat pump system and a detailed quote which will include running costs. If you are happy to go ahead with your Octopus heat pump installation you will be asked to pay a deposit and a date will be allocated for installation.

How much does a heat pump cost in the UK? Octopus Energy aims to supply and install a heat pump for the same price as a traditional gas boiler.

In the UK according to the Energy Saving Trust, an air-to-water heat pump typically costs between £9,000 and £11,000 but Octopus aims to more than half this cost!

It looks as though this has been a long-term plan in the making. Octopus Energy intends to use the £5000 government grant to help roll out their heat pump revolution in volume. The government grant can partly fund up to 90,000 new heat pumps over the course of the next 3 years.

By having their own Octopus research centre and in-house training for Octopus energy heat pump installers all they really needed to do is bring down the cost of a heat pump.  I am guessing that by being able to manufacture their own heat pumps in bulk they can now drive down the cost. The government grant could help kick start interest and in turn, help put the wheels in motion.

How can Octopus Energy expect to bring down the price of a heat pump so dramatically? 

By being able to combine the reduced installation cost and reduced hardware cost, Octopus will significantly bring down the price of a complete heat pump installation package. 💃 Now have you stopped wondering why they have a gigantic research and training centre?  💭

If Octopus can supply their own installers and manufacture the heat pumps themselves they can determine any profit margins needed to make it viable. If Octopus is happy to focus on low-profit margins with the main vision being just to get these heat pumps into people’s homes then the customer will see the price of a heat pump drop dramatically!

How much does a heat pump cost to run in the UK? Is there going to be an Octopus Energy heat pump tariff is the big question?

Yes, in December 2022 Octopus launched a specific heat pump tariff called Cosy Octopus.  This has two discounted periods during the day so you can heat your house for less. It has been a much-anticipated tariff that has some customers divided as the discount period isn’t as cheap as either of the Octopus EV tariffs BUT you do get a double dip. The Cosy Octopus tariff gives 6 hours of off-peak electricity so it’s not to be sniffed at!

Octopus heat pump tariff

At the moment if you own a heat pump you might be feeling the pinch. The scenario is the same, however, if you have a gas boiler. The cosy Octopus tariff should help make running your system more competitive when compared to gas.

The energy crisis has seen wholesale energy prices for both gas and electricity rise significantly over the last few months.

If you would like information on other Octopus tariffs you can read my full review of all Octopus Energy tariffs including up-to-date prices on my comparisons page.  It is updated daily and keeps an eye on the wholesale energy market. Knowing if and when to switch and fix your energy tariff in the current climate is really important, I hope it helps!

Are heat pumps worth it in the UK? 

In the UK, the gas that we burn in our homes to keep us warm and to cook our food accounts for about 14% of our emissions. So in order to help the planet we really need to address this issue, and fast!

The technology involved in an air source heat pump has been around for around 160 years. A fridge, in its simplest form, is a heat pump in reverse. It takes air around it and makes it cold.  Heat pumps are greener as they use electricity instead of gas to heat your home. Now thousands of people could discover heat pumps are an option for them thanks to the government grant.

Do heat pumps save on running costs in the UK?

Heat pumps powered by renewable electricity are the way forward for many homeowners. They are:

  • Around three times more energy-efficient than a gas boiler, without the carbon emissions
  • Reduce hot and cold spots within the home by providing consistent and comfortable warmth.
  • A heat pump has fewer parts and safety concerns. (No worries about carbon monoxide)👏 So a heat pump can last longer and needs less maintenance.

Right now, our world relies on stealing energy and natural resources that we can’t give back. If you want to continue to be a part of the natural world, you have to act like nature. With heat pumps, you don’t have to burn anything, you don’t have to steal anything – we’re mimicking nature. Even when it’s cold outside, we can take some of that energy and produce something with it. – Peter Konowalczyk @Octopus Energy.

I don’t yet own a heat pump but I would love to get rid of my gas-guzzling boiler! Using fossil fuels to heat my home isn’t really what I want for the long term but sadly I have recently moved into a new build and they installed a gas boiler. 🥲 A new home builder should really be required to install a heat pump in any new build. That would make so much sense!

Here are some frequently asked questions about heat pumps. They might help you answer if air source heat pumps work in the UK.

How noisy is a heat pump?

The general consensus is that the sound level the heat pump emits is similar to the level of a whispered conversation. If your heat pump is making any more noise you really need to get your installer to revisit.

Does a heat pump get the water hot enough?

Yes, I have read one review where the homeowner was getting temperatures up to 50 degrees C. I think that’s fine for any home. You can turn up the water temperature by clicking a few buttons.

How much are the energy bills when you have a heat pump?

Similar to running a gas boiler it depends on how long you have it on for. One of the good points of going all-electric is that you can get rid of your gas meter and have no gas service charges on your bill. Up until now, gas has been significantly cheaper than electricity to heat your home BUT things are changing. It is a case of watching this space.

Do you need to change your radiators and pipes when you install a heat pump?

If your house is fairly new or you have new radiators it’s possible that you won’t have to change anything. Octopus will do a survey before installation to give you a good idea before you go ahead. If you need to change some radiators in your home this will be included in their quote.

If you are planning on doing home renovations or are simply ripping out your old boiler with the government grant it’s a good time to consider installing a heat pump.

Quite frankly Octopus Energy has such an amazing reputation they are going to be the go-to supplier in my opinion for heat pumps.

Is it true that you can only have a heat pump if your home is really well insulated?

It goes without saying that to ensure we don’t waste energy we have to ensure that our homes as well insulated. If the name of the game is to reduce your energy consumption then it really is a no-brainer BUT exactly the same argument applies to a gas boiler. It makes no sense to say it is totally fine to inefficiently heat your home with fossil fuels but completely unacceptable to do the same with a heat pump. Both waste energy BUT the gas boiler results in higher carbon emissions. 🏭

Can you have a heat pump if you live in a flat?

I follow @Richardcasson on Twitter. Richard works for Greenpeace and lives in a flat. He has recently had a heat pump fitted am quite sure from the photograph he isn’t on the ground floor. So yes you can have a heat pump installed if you live in a flat. 👏


“Octopus has already committed £10million investment to its research and development and training centre dedicated to the decarbonisation of heat and has begun training engineers at the rate of 1,000 per year. – Greg Jackson, CEO Octopus Energy “

I am delighted that Octopus Energy is my energy supplier!! Well done Greg Jackson and the team at Octopus Energy you are leading the way yet again! 👏 You make this all seem so effortless and you keep coming out so far ahead of any of the other suppliers! You should all be so proud of how Octopus Energy has scaled up and retained its core values.  Plus I have to say I love the stylish hard hats. Clem, your Director of External Affairs looks like she is having far too much fun BUT that’s why you always nail it!

Heat Geek course review – Why share the love?

Just be totally transparent I get a referral fee if you use any of the links to the Heat Geek course and sign up.  I also want to highlight that I didn’t go looking for their referral program. I have been following Heat Geeks for several months on Twitter. They are really funny and I love their content. I just spotted the link when looking at their website. Yep, I was looking at their site out of pure pleasure.

Heat Geeks are so passionate about renewables it’s infectious. That’s right, someone who has no connection with the heating installations finds their content interesting! 🤯  So if you are in the industry you are going to love it!  Get ready to help your business and the planet! (People like me will need your help so thank you!!)
