Getting your home heat pump ready

The Government have just increased their heat pump grant from £5,000 to £7,500!
Heat pumps are so hot right now that wait time for a survey date is currently several months. Our team are working quickly to support everyone waiting, so we'll be with you as soon as we can.

To claim this huge saving, 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.

🔥 Your home should not have any loft or cavity wall insulation recommendations on your EPC. If you do need insulation, we can help with that too.

🔥 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 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 70%. 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.

Visit our Heat Pump Hub to find out more.

How does a heat pump compare to a gas boiler?


We surveyed 100 heat pump customers to find out how their heat pump compared to their previous gas boiler, 3 months after installation.

87% of people said their heating was just as, or more comfortable than their old boiler.

80% say their heat pump is less noisy or just as noisy compared to their old boiler.

79% said it costs the same to run or less.

To run, a heat pump differs a little from a traditional gas boiler, here’s 4 pointers explaining how:

1. Heat pumps take longer to warm up

A heat pump uses cooler water to heat your home, so it can take a little longer to warm up to your chosen temperature. That means it’s best to set a schedule for the heating to come on before you get up in the morning.

2. Heat pump controls are simple to use.

You’ll be able to set your schedule and temperature from wherever, whenever with an app on your phone. Plus, you’ll have both a digital control panel and thermostat in your home - so you’re free to use whichever works best for you. Check out our handy video on how to set up a schedule for a little insight into how it works:

3. Octopus smart tariffs can help you save money

With a smart tariff you can heat your water cylinder at the greenest times at cheaper rates, saving you money with smart energy usage. Check out our dedicated heat pump tariff, Cosy Octopus:

4. Your heat pump will adjust to the weather automatically

To help you save energy, we set your heat pump to monitor how hot or cold it is outside, and adjust the temperature accordingly.

How much does an Octopus heat pump cost?


Our standard installation costs range from as low as £500. It can cost more if you have a larger home or non standard installation but but virtually all our quotes are less than the national average of £5,500. Both of these prices include the new government grant of £7,500.

We’ve been working hard to bring heat pumps to you at the lowest price possible. 90% of our heat pump quotes are lower than the national average. (When you factor in the government grant that's a cost 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 EPC info from the national database, to calculate your price.

This online quote will be for a standard installation, which the majority of homes are. The next step after your quote is a home survey, at which point we’ll be able to see if your home requires any non-standard work to make it heat pump ready (this is rare, but it happens from time to time).

What's included in the price of a quote?


Your quote includes everything you need for a standard installation:

  • A brand new Daikin heat pump sized for your home’s heating needs
  • A new Daikin heat pump-compatible water cylinder
  • Any necessary radiators for your new system
  • Plumbing & electrical bits needed to fit your new heating system
  • Labour to complete your installation
  • 5-year warranty on your heat pump
  • 2-year warranty on all other parts
  • 5-year warranty on labour & workmanship
  • £7,500 Boiler Upgrade Scheme grant (we apply for this grant on your behalf)
    Terms & Conditions apply; labour provided based on standard installation

There may be some additional work or tests required to make your home heat pump ready at an extra cost, such as planning permission in some cases or insulation if you need it (to reduce heat loss). Following your survey, we'll be able to confirm precisely what work is necessary so that you can make an informed decision on whether you'd like to go ahead.

The Boiler Upgrade Scheme - how does the new £7,500 announcement affect me?


The Boiler Upgrade Scheme is a government grant to help support the cost of of replacing fossil fuel heating systems with a heat pump.

On the 21st September government announced they are increasing the funding to £7,500 from 23rd October 2023. Following this announcement, we've taken the decision to apply this to all of our quotes now subject to this being implemented as announced.

We'll apply this directly to your heat pump quote, so you only need to pay the net amount. If you've already received a quote with the previous funding (£5,000) that's no problem, we'll make sure this is updated in your final sales agreement.

What’s the process to get a heat pump with Octopus Energy?


Fill out our quick online form and we'll provide you with an instant quote. You can speak to our team about any questions you have, and if you choose to accept your quote, we'll take a £500 fully refundable advance payment and book in your home survey.

During the home survey, our experts will check the heat loss of your home and discuss where your heat pump will go. We’ll use this time to finalise your heating design and double check that a heat pump is suited for your home.

We’ll then send you an assessment of the home survey in a final sales agreement. Our team will be available to answer any questions you may have. If you accept the agreement, our install coordinators will be in touch to arrange and manage your install. We’ll then take your final payment after installation.

After installation, our dedicated aftercare team will be available by phone or email, 7 days a week, to help with any queries you have. Your heat pump comes with a 5 year warranty, and 2 year warranty for the other products we install (like your hot water cylinder and radiators). Find out more about our service plans.

How much space do I need?


The outside bit of a heat pump is roughly 1m x 1m x 2m (or to help you visualise - the size of a moped). It needs a space of around a meter in-front and to each side to breathe.

heat pump outside space

Inside you need space for a hot water tank - 2m x 1m x 1m (the size of a modern fridge freezer), on the ground or first floor of your home (the closer to the outside the better).

The cylinder can also be installed in a garage, outdoors in a purpose-built store, or in the loft, but this may decrease efficiency (it takes more energy to heat the water when the cylinder is exposed to the cold).

cylinder indoor space

If you don't have the room right now, new space saving technology is being developed all the time, so expect this to come down considerably in future (more on this to come 👀).

Where are you currently installing?


We’re currently installing heat pumps across most of England & Wales.

We’re working to extend our tentacles across the rest of the UK as quickly as possible. If you’re outside of our service area now, we’ll let you know as soon as we get to you.

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.

Should I wait for a Cosy 6 heat pump?


In September we announced our new 'Cosy' heat pump - our super smart, super green new Octopus heat pump! Our smallest model 'Cosy 6' will be available in the next few months alongside our current heat pump range. If you are interested, please sign up on our Octopus heat pump page, and we'll let you know which options are available to you post-survey.

90% of our heat pump quotes beat the national average:
We compared all of our heat pump quotes for July 2023 to the UK national average quote, which government
publish here every month. We found that 90% of our Octopus quotes were below the national average price of £13,065 before any grants, or £5,565 when you factor in the new government grant.

Cut carbon emissions by around 70% with a heat pump:
We've based this on the following carbon efficiency calculation:

Gas CO2 = (A/C*D) = 2.55 tonnes

Electricity CO2 = (A/B*E) = 0.78 tonnes

Carbon saving = 1.7 tonnes or 69%

Where A - E are:

A - 10 MWh typical energy demand for heating and hot water for a 3 bed property

B - 3 heat pump seasonal coefficient of performance

C - new boiler efficiency of 82.5% (BEIS study)

D - Gas fuel emissions of 210 gCO2/kWh (SAP 10)

E - Electricity fuel emissions of 233 gCO2/kWh (SAP 10)

A heat pump will keep you toasty, even at - 20°
Air source heat pumps can actually work in temperatures as low as -20 °C! In Norway, one of the world’s coldest countries, every other home has a heat pump (so they must work pretty well). When it gets very cold, the heat pump will need to use a bit more energy than usual to keep your home cosy, but fortunately we only see temperatures below -10°C a few days per year, and even then, a heat pump will still function more efficiently than a gas boiler.

A heat pump is 4x more efficient than a gas boiler
Heat pumps can deliver several units of heat for each unit of electricity. For every 1 kWh of electricity you put in, you could get up to 3.33kWh of heat out, which is an efficiency of 333%! This is because heat pumps don’t create heat, but move existing heat from nature into your home (like an air conditioner or refrigerator, but in reverse).

Alternatively, when you burn stuff to generate heat (like gas, oil, or wood), you are instead creating heat by converting matter to energy - so you can never get more than one unit of heat for each unit of energy you burn. Gas boilers in UK homes are only around 83% efficient, so for every 1 kWh of gas you put in, you get 0.83kWh of heat out, which is 4x less efficient than a heat pump (3.33/0.83 = 4.1)

Set it and forget it:
Operating a heat pump is easy. We’ll recommend an ideal temperature based on your home and budget, then help you to set the timer based around your routine and when electricity is cheapest. Once set, our customers say that maintaining a comfortable temperature is far less hassle than their old gas boiler.

Cosiness you can count on
Before installation we do a thorough home survey to ensure the heat pump system we install is optimised for your space. When surveyed, 90% of our customers said the warmth from their new heat pump was either just as comfortable or even more comfortable than their old boiler.
