Electrify your home with Octopus Smart Tech
More customers turn to heat pumps and solar since start of Iran war
With gas prices spiking, more households are investing in solar and heat pumps to gain independence from global events and a volatile market. Our founder, Greg, spoke to the BBC about the "huge jolt" in orders – and how electrification is leading the way to a smarter, greener and more resilient energy system.

Take control of your energy bills and wave goodbye to gas. With smart tech and clever tariffs, thousands of homes are already electrifying — using power when it’s cheapest and greenest. It's time for you to the reap the rewards.
Welcome to your new home set-up
Picture this. It's a sunny day, so your solar panels create electricity while you potter around the garden, and your battery stores leftover energy to use later. As you kick your feet up in front of the telly, you're kept perfectly toasty thanks to your heat pump. Overnight, your EV charger provides the juice when energy's greenest and cheapest.
Each bit of tech works brilliantly on its own, but together they become something much bigger: a home that powers itself.

Our claims explained
Heat pumps vs Gas boilers
Cost to run: Cosy heat pump customers on the Cosy Octopus tariff saved an average of £219 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 19 March 2025 and 18 March 2026, using tariff rates at the time.
We compared this to the cost of producing the same amount of heat with a typical UK 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 3% of customers).
Actual savings vary depending on system design, tariff choice, home insulation and energy use.
Efficiency: 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 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.
This comparison is based on typical real-world performance of Octopus Cosy heat pumps and typical UK domestic gas boilers. Actual efficiency will vary depending on the property, system design, and usage.

Emissions: Cut carbon emissions by around 80% with a heat pump
A typical medium-use home could reduce operational heating carbon emissions by around 85% using an electric powered Octopus Cosy heat pump compared to a typical UK domestic gas boiler, depending on factors like home efficiency, system design and usage, based on the following calculation:
Gas CO2 = (A*D) = 2.42 tonnes per year
Electricity CO2 = (A/B*C*E) = 0.37 tonnes per year
Carbon saving = 2.05 tonnes or 85%
Where A - E are:
A - 11,500 Ofgem gas consumption values for a typical medium-use home
B - 360% typical seasonal coefficient of performance from our fleet of Octopus Cosy heat pumps
C - 85% typical gas boiler efficiency from a BEIS study
D - Gas fuel emissions of 210 gCO2/kWh (SAP 10.2)
E - Electricity fuel emissions of 136 gCO2/kWh (SAP 10.2)
Based on these sources, heat pumps typically produce lower operational emissions when heating the home than gas boilers.

Ev chargers: Save 85% vs public charging when you power up at home with Intelligent Octopus Go
A slow or fast charge (<50 kWh) with one of the UK’s public charging points costs an EV driver 54p/kWh on average (last checked April 2026). With Intelligent Octopus Go, you smart charge for only 8p/kWh and save 85%.
1 - 8/54 = 0.85 or 85%
Save £820 a year on your fuel costs with an EV vs a petrol car
This is the difference in annual cost to smart charge an average electric car on our Intelligent Octopus Go tariff (£174) versus fueling the average petrol car (£994).
Annual cost to charge with Intelligent Octopus Go = A*B*C = 7,100 miles * 0.306 kwh/mile * 0.08 £/kWh = £174
Annual cost to fuel a petrol car = A*D = 7,100 miles/year * 0.14 £/mile = £994 per year
A - 7,100 average annual mileage (gov.uk)
B - 0.306 kWh/mile average electric car efficiency (EV database)
C - 8 p/kWh Intelligent Octopus smart charging rate, assuming you're smart charging for a maximum of 6 hours/day. Check if you're eligible.
D - 0.14 £/mile average cost per mile for a petrol car (gov.uk)
