The care plan that does the thinking for you
Cosy Care: Our Cosy heat pump care plan (£12/month)
Traditional heating cover is simple: wait for a problem, then send an engineer.
Cosy Care does things differently.
We use smart data from your heat pump to monitor its health, optimise its performance, and catch issues early. We can even fix many problems remotely, without you needing to lift a finger.
And for even more peace of mind, we'll include an optional annual engineer visit too. Unlike traditional service plans, we don't require it to keep your warranty valid. We trust our technology to tell us far more about your heat pump than a single annual inspection ever could.
What you get
Full 8 year warranty
We match your 8 year Cosy manufacturer warranty with a full 8-year workmanship warranty.

Frequently asked questions
Right now, our Cosy Service Plan is exclusively for homes where Octopus installed the heat pump.
However, you don’t need to get your home's energy from us to sign up - though we’d absolutely love it if you did!
Nope! We use clever remote monitoring (tech-speak: telemetry) to keep a watchful eye on how your heat pump is doing.
If it's purring perfectly: Every 12 months, we’ll offer you a service. If our data shows everything is running beautifully and you choose to skip it, your warranty stays 100% intact.
The only exception: If our data spots a snag and we reach out to book a vital check-up, you do need to let us in. If you repeatedly ignore or cancel these critical visits, your warranty could be voided.
To keep your Cosy Service Plan valid, the service does need to be done by one of our own expert Octopus engineers. They know these systems inside out.
The plan runs on a 12-month term that auto-renews so you can set it and forget it. But we don't believe in trapping people:
Cancel anytime: If your circumstances change, you can cancel whenever you like. If you've already had your annual service you'll need to pay up to the end of the annual term.
Changed your mind? If you cancel but want back in, you have 90 days to rejoin. You'll just need to pay for those missed days to bring your coverage fully up to speed.
No sneaky renewals: We’ll always email you a full month before your annual renewal date to give you plenty of notice.
It all depends on whether we've already done the work:
Before your annual service: Completely free to cancel. No fees at all.
After your annual service: If we've already serviced your heat pump, you’ll just need to pay out the remainder of your 12-month term.
Yep, absolutely. Every price we quote includes VAT.
Yes, but acting fast comes with a perks! To sign up for our Cosy service plan, your heat pump just needs to be less than 2 years old from its installation date.
Bonus tip: If you sign up within the first 60 days of your installation, you’ll lock in our best-value rate.
Once you're in, we’ll keep the good times rolling and cover your system for a maximum of 8 years from that original install date.
If something needs fixing that falls outside your warranty, we will always give you a clear quote before we do any work.
We play fair, and we ask that you do too! We don’t put a cap on covered repairs, parts, or engineer call-outs for genuine heat pump glitches. However, our Fair Use rule means that if our engineers are repeatedly called out for non-issues, or if there’s clear evidence of accidental damage, neglect, or a bit of DIY tampering, we do reserve the right to cancel the plan. Let’s keep things honest and smooth.
Following your Cosy heat pump install, we'll be in touch via email to get your payment set up.
From there, you'll pay £12 a month unless you decide to cancel.
The details:
Price Promise: Whichever option you choose, your monthly cost is paid via Direct Debit and is fixed for the first 2 years (and reviewed every 12 months after that). Your first payment will leave your account 30 days after your plan officially kicks off.
Already an Octopus Energy customer? To keep life simple, we’ll just roll this into your existing energy Direct Debit so it's all in one handy place.
Not an Octopus customer? No worries at all—we’ll set up a shiny new Direct Debit just for this plan.
Yes! Think of it as keeping the lines of communication open. Because this is an active, data-led care plan, your system needs to stay connected to our smart data network. This allows our clever tech to quietly monitor its health in the background and spot any hiccups before they become real headaches. No data, no magic!
When it's time for your annual check-up, we'll pop an email into your inbox with a quick link to pick a date and time that suits you.
Lost the email? Want to chat sooner? No problem. Just drop our team a line at hello@octopus.energy or give us a ring on 0808 164 1088.
Our engineer will give your system a thorough top-to-bottom health check. Think of it as a bit of a spa day for your heating. They will:
Check water pressures and test electrical connections.
Clean out filters and clear away any debris from your outdoor unit.
Tweak your settings to ensure you're getting maximum warmth for minimum cash.
The service plan stays with the house (and the heat pump!), which is a fantastic selling point for whoever buys your home. Just let us know your moving date and we'll handle the paperwork to transfer it over to the new owners. Easy peasy.

Cosy heat pump customers on the Cosy Octopus tariff saved an average of £205 last year compared to using a gas boiler running at 85% efficiency on our standard variable tariff
This figure is based on the actual energy consumption of all Cosy heat pump customers on a Cosy Octopus tariff between 1 Oct 2025 and 1 Oct 2026 , using tariff rates at the time.
We compared this to the cost of producing the same amount of heat with a gas boiler operating at 85% efficiency, priced using our Flexible Octopus (standard variable) tariff at the same time.
Savings from gas standing charges were included only for customers who had fully removed their gas supply (less than 2% of customers). Actual savings vary depending on system design, tariff choice, home insulation and energy use.
Our typical heat pump price is £4,064, which is lower than the national average of £5,408
This is the median post-survey price from all of our heat pump quotes after the £7,500 Boiler Upgrade Scheme has been applied, between 01/06/2026 and 30/09/2026. The national average is taken from the Boiler Upgrade Scheme statistics: April 2026 – median cost of installation Q3 2026.
Cut carbon emissions by 85% with a heat pump
This is the typical reduction in heating carbon emissions using an electric powered heat pump compared to a gas boiler.
The carbon breakdown
Gas CO2 (tonnes per year) - 2.00
Electricity CO2 (tonnes per year) - 0.31
Carbon saving (tonnes per year) - 1.69
Data sources and assumptions
Gas Energy Usage (kWh) 9500 (Ofgem medium use gas usage (Oct 2026))
Heat Pump Efficiency 312% (typical seasonal coefficient of performance from a fleet of Octopus high temperature heat pumps)
Gas Boiler Efficiency 85% (The typical gas boiler efficiency from a BEIS study)
Gas fuel emissions of (gCO2/kWh) 210 (SAP 10.3)
Electricity fuel emissions of (gCO2/kWh) 119 (SAP 10.3)
Based on these sources, heat pumps typically produce lower operational emissions when heating the home than gas boilers.

We're the largest heat pump installer on the Boiler Upgrade Scheme
Based on Octopus benchmarking against Ofgem reports from 2026, and we've continued to grow since.
Our customers love their heat pumps!
93% of people say it's the same or more comfortable than their previous boiler
87% say it costs the same to run or less
83% say it's the same noise or less than the previous boiler
90% say it's just as easy or easier to maintain
We survey all our heat pump customers 3 months post-installation to see how they find their heat pump compared to their previous gas boiler. Survey results are taken from a sample of 2,837 customers:
Comfort: 93% of people say it is the same or more comfortable than their previous boiler.
Running Costs: 87% say it costs the same to run or less.
Noise: 83% say it is the same noise or less than the previous boiler.
Maintenance: 90% say it is just as easy or easier to maintain.
A heat pump is around 4x more efficient than a gas boiler
Heat pumps don't generate heat by burning fuel. Instead, they transfer existing heat into your home. This means they can deliver multiple units of heat for each unit of electricity used.
Based on performance data from a fleet of installed Octopus Cosy heat pumps, typical real-world seasonal performance (SPF or SCOP) is around 3.6. This means around 3–4 kWh of heat is delivered for every 1 kWh of electricity used (an effective efficiency of 300–400%). By comparison, typical UK domestic gas boilers operate at around 85% efficiency, delivering approximately 0.85 kWh of heat per 1 kWh of gas used. On this basis, a heat pump can be around 4× more efficient than a typical gas boiler.
All our heat pumps are independently tested by the Building Research Establishment (BRE), with SCOP values published on the Microgeneration Certification Scheme (MCS) product database. Actual efficiency will vary depending on the property, system design, and usage. For more information, explore our Octopus Cosy heat pump fleet performance dashboard.

Heat pumps give reliable, consistent heating and hot water
The heat pump user survey report by Nesta from May 2023 summarises that "users are highly satisfied with their heat pumps". It states: "People living in England, Scotland and Wales who own their home and use a heat pump to heat it are satisfied that heat pumps are safe, reliable, quiet heat sources that are effective for space heating and producing hot water." Find the full report here.
The Cosy heat pump is quiet
Heat pump sound power levels are verified by an independent, third-party laboratory as part of the testing process for inclusion on the MCS product database. The laboratory verifies the sound power on the A-weighted decibel curve, as A-weighting closely aligns to how humans perceive "loudness".
All heat pumps are measured using EN14511 standards to ensure uniformity across manufacturers and models. Our Cosy 6 heat pump has a verified sound power level lower than many other heat pumps of the same capacity.
Heat pump heating makes the air healthier in your home
Homes with a heat pump emit far less harmful nitrous oxide (NOx) emissions than those with gas boilers and cookers, significantly reducing asthma and other respiratory illnesses. According to the Sustainable Markets Initiative Cleantech Homes report.
A heat pump can add thousands to your property value
Analysis by the Department of Land Economy at the University of Cambridge suggests a 16% value uplift for new-build homes with enough solar and battery storage to eliminate energy bills. A further study of over five million existing properties indicates a 2-3% value increase for existing homes with solar panels or heat pumps (versus like-for-like gas-heated homes), according to the Sustainable Markets Initiative: Cleantech Homes report, 2024.
As of July 2026, the average house price in the UK is £272,611 according to the Land Registry. Therefore, a 2-3% value increase for an average house priced at £272,611 would be between £5,460 and £8,190.
Heat pumps typically last longer than gas boilers
The expected lifespan of a typical gas boiler is 10–15 years. A heat pump typically has a lifespan of 15–20 years, with UK government research indicating an average of around 20 years. Manufacturer Daikin reports similar ranges. Actual lifespan depends on factors such as installation quality, maintenance, usage patterns, and operating conditions.
