We’ve had a lot of conversations lately with homeowners across Exeter and the surrounding areas who are wondering:

“Should I be switching to a heat pump?”

The government’s been pushing low-carbon heating. You’ve probably seen headlines, maybe even heard from friends or neighbours who've made the switch. But is it actually worth it? Is it even right for your home?

Here’s what you really need to know — no jargon, no sales fluff, just straight answers based on what we’re seeing in homes across Devon right now.

First, What Is a Heat Pump?

A heat pump is basically a super-efficient electric heating system. It works by extracting heat from the outside air (or ground) and using it to heat your home and hot water.

There are two main types:

• Air Source Heat Pumps (ASHP) – most common, easier to install

• Ground Source Heat Pumps (GSHP) – more efficient but need digging

Think of it as a fridge in reverse. Instead of cooling the inside, it draws in outside warmth — even when it’s cold — and pumps it into your home.

Will a Heat Pump Work in Your Home?

This is the big one. And honestly? Not every home is ready.

Here’s what typically makes a good candidate:

• Decent insulation (walls, floors, loft)

• A well-sized hot water cylinder (they don’t work with combi systems)

• Room for an outdoor unit

• Radiators large enough to run at lower temps

We’ve been to properties in Exeter where heat pumps work brilliantly — especially newer builds or well-insulated renovations. But older, draughty homes? You might struggle to keep warm unless you've upgraded your insulation first.

How Much Does a Heat Pump Cost in 2025?

Here’s the current ballpark in the UK:

System TypeTypical Installed Cost (2025)Air Source Heat Pump£7,000 – £11,000Ground Source Heat Pump£15,000 – £25,000+

📉 Government Incentives
As of April 2025, the Boiler Upgrade Scheme still offers grants of up to £7,500 for heat pump installations. But that doesn’t cover insulation, pipework changes, or new radiators — which might be needed.

And that’s the thing: the heat pump itself might be covered partly by grants, but the total upgrade could be more.

How Do Running Costs Compare?

This one really depends on your setup.

In a well-insulated home:

• Heat pumps can be cheaper than gas to run — especially with smart controls and off-peak electricity rates.

• If your home isn’t efficient, you might end up paying more than with a modern boiler.

It’s not always cheaper — but it is much better for the environment, and it future-proofs your home as gas gets phased out.

What About Servicing & Maintenance?

Heat pumps are low maintenance — but they do need annual checks to keep warranties valid and ensure efficiency.

Good news? We’re already planning service packages for both gas boilers and renewable systems, including optional add-ons for things like electrical cover. So as these systems grow in popularity, you’ll have peace of mind locally with EPM.

Common Myths We Hear Around Exeter

• “They don’t work when it’s cold” →  False. Most air source heat pumps work down to -15°C. Exeter doesn’t see that often.

• “They’re noisy” → Modern units are quiet — often no louder than a fridge.

• “They’ll heat my hot water instantly” → Not quite. You’ll need a cylinder, and reheating takes longer than a combi.

Should You Replace Your Boiler With One?

If your boiler’s on the way out, it’s worth getting a heat pump survey — but don’t feel pressured. In some homes, a high-efficiency combi or system boiler still makes more sense.

We’ve had customers try to rush the switch, only to find they’d need major insulation and radiator upgrades to make it work.

That’s why we always take a measured, no-pressure approach.

Final Thoughts from EPM

Heat pumps aren’t just a trend — they’re a key part of the UK’s long-term heating strategy. But they’re not for everyone, and certainly not one-size-fits-all.
