Octopus Energy Referral Code 2025 | £50 Free Credit
Looking to ditch your gas boiler and heat your home more sustainably? Octopus Energy heat pumps are a cleaner, greener way to heat your home—and thanks to government support and Octopus’s in-house installation service, making the switch has never been easier.
A heat pump is a modern, low-carbon alternative to traditional home heating systems. Instead of burning fossil fuels, it works by extracting ambient heat from the outside air and transferring it into your home via a refrigerant cycle — even in sub-zero temperatures. Think of it like a fridge in reverse: it moves heat in rather than out.
Octopus installs air source heat pumps, the most suitable type for the majority of UK homes. These systems work efficiently with radiators or underfloor heating and can supply hot water when paired with the right cylinder.
Not only do they cut carbon emissions, but they also lower running costs when used with smart tariffs — especially Octopus’s green energy options.
Unlike gas or oil boilers, which burn fuel to generate heat, heat pumps move heat, making them dramatically more energy-efficient and climate-friendly.
Here’s a simple comparison to help you decide if heat pumps are for you:
| Feature | Heat Pump | Gas Boiler |
|---|---|---|
| Lifespan | Up to 20 years | Up to 15 years |
| Annual Heating Costs | ~£1,444 (with Cosy Octopus tariff) | ~£1,849 (on flexible Octopus tariff) |
| Efficiency | Around 330% (3.3x energy output) | Around 85% |
| Carbon Emissions | ~470 kg CO₂/year | ~2,830 kg CO₂/year |
| Energy Source | Electricity (can be 100% green) | Fossil fuel (natural gas) |
| Future-Proof | ✅ Designed for net-zero homes | ❌ Must be phased out to meet targets |
| Maintenance | Low – annual checks recommended | Medium – regular servicing required |
Conclusion: Heat pumps are the future of home heating — cleaner, more efficient, and better aligned with the UK’s move to net-zero.
Heat pumps use electricity to extract heat from the air or ground—like a reverse fridge—and work even in sub-zero temperatures. They’re up to 4x more efficient than gas boilers, and when powered by renewable electricity (like Octopus’s 100% green tariffs), they offer ultra-low carbon heating.
Heat pumps use renewable energy from the air to heat your home, significantly reducing your carbon footprint compared to gas or oil boilers.
Modern heat pumps deliver up to four times more energy than they consume, meaning you get more warmth for less energy use.
Pair your heat pump with a green energy tariff from Octopus, like Agile or Cosy, to power your heating with 100% renewable electricity.
Smart controls help heat your home when electricity is cheapest—saving you money while keeping you comfortable.
Heat pumps are a key part of the UK’s shift to net-zero. Installing one now means your home is ready for the future of low-carbon living.
