If you’ve been put off by the idea that heat pumps are too expensive, you’re not alone. But here’s the good news, switching to a low-carbon heating system might cost less than you think, especially when you compare it to replacing a gas boiler.
Heat Pumps vs Boilers
Replacing a gas boiler isn’t exactly cheap:
- A combi boiler replacement typically costs £2,000–£3,000
- A system or conventional boiler replacement usually comes in at £3,000–£4,000
Now let’s look at a standard air source heat pump installation.
A typical install (before grants) costs £7,000–£10,000, and that includes:
- Supply and installation of the air source heat pump
- Outdoor and indoor units
- A new, heat pump-compatible hot water cylinder
- Smart controls or a simple thermostat
- Full system design, pipework connections and commissioning
- MCS certification, which is required for government funding
That might sound like a big leap, but with grants available in Scotland (up to £9,000 through Home Energy Scotland), the difference in cost could be as little as £2,000 when compared to replacing a conventional boiler.
You Don't Need To Do Everything At Once
At Renewable Heat, we understand that heating upgrades are a big decision, and every home is different.
You don’t need to rip everything out and start from scratch. In fact, we can install a heat pump in your home today, and run it at slightly higher temperatures while keeping your existing radiators and pipework. You’ll still start saving money and reducing your carbon footprint from day one.
Then, over time, you can choose to:
- Upgrade your radiators to more efficient models
- Replace your hot water cylinder
- Add in solar panels and battery storage for even bigger savings
- Fine-tune your system with smart controls and better zoning
We’ll take you on the journey, step by step.

- Advise on energy tariffs that suit heat pump usage
- Help you access funding through Home Energy Scotland
