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…

A heat pump illustration
  • 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.

I got a call from Octopus literally a week after requesting to book a home survey. About 15 minutes after the surveyor left I received a quote and I paid the deposit within 10 minutes. It was an absolute no brainer. I would never complain for the price I paid and the product is exceptional.

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).

How is my Fixed Price Quote calculated?

×

We generate your fixed price quote using the information you provide us when you request a quote and EPC data on your home from the national database. This allows us to generate, with a high degree of accuracy, the cost of a standard installation for your property.

If your home requires any non-standard work to make it heat pump ready (this is rare, but it happens from time to time) our team will let you know after your home survey.

How does your pricing compare to other installers?

×

90% of Octopus Energy heat pump quotes are below the UK average quote, which government publish monthly here. In July 2023 for example, the average UK heat pump cost was £13,065 before any grants, while 90% of our Octopus quotes cost less than this. When you factor in the new government grant that's a cost of £5,565.

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

×

Fill out our quick online form and we'll provide you with a fixed price 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.

90% of our heat pump quotes beat the national average:
We compared all of our heat pump quotes for July 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)

2,000,000 Swedes can't be wrong
The Eco Experts claim that Sweden have 19,510 heat pumps per 100,000 people, (last updated on 26th Jan 2023).
As of 11th April 2023 the population of Sweden is 10,276,357 so 19.509% of this figure = 2,004,814 homes with heat pumps in Sweden.

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.

The £250 Daikin discount - how does it work?

×

For heat pumps installed between June 21st 2023 to March 31st 2024, heat pump manufacturer, Daikin, will be cutting £250 off the supplier price of their heat pumps. And unlike many suppliers, we will be passing that saving directly on to our customers. This £250 discount will be taken off the full price of your heat pump at payment stage.

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.

If you have a complaint, please email heat@octopus.energy, or you can find our complaints procedure here.
