1. Breaking Down the Price Tag: What Influences Installation Costs?
Installing an air source heat pump isn’t a one-size-fits-all deal. Prices vary by:
- System type (ducted vs ductless)
- Unit capacity and efficiency
- Complexity of installation
- Additional eco-friendly upgrades
Let’s take each in turn.
1.1 System Types: Ducted vs Ductless
Ducted systems link into your home’s existing vents. They cost more in labour but spread heat evenly. Typical installed price: £8,000–£12,000 for a mid-sized house.
Ductless (mini-split) pumps go straight to wall-mounted indoor units. They’re ideal for extensions or where ducts don’t exist. You might pay £5,000–£9,000 installed, depending on how many zones you need.
1.2 Size and Capacity
Bigger homes need more kW output. A 4 kW pump suits a small flat. An 8–12 kW model handles a three-bed semidetached house. Expect unit costs between £2,500 and £6,500 before installation.
1.3 Energy Ratings: SEER and SCOP
Efficiency matters. High SEER (cooling) and SCOP (heating) ratings shave running costs. A top-rated pump with SCOP over 4.0 costs more upfront—often £1,000–£1,500 extra—but can deliver 25–30 % more savings per year.
1.4 Installation Complexity
Is your house a period property with solid walls? Budgets must cover additional drilling, pipework and specialist insulation. Tight loft spaces or funky layouts can also add to labour time. Factor in £500–£2,000 of extra labour in tricky installations.
1.5 Zero-Carbon Refrigerants
Megawave champions R290—a zero-GWP refrigerant. It’s pricier than standard options but cuts your carbon footprint to near zero. Adding R290 tech to your system tacks on around £300–£600 to the unit price. Worth it, if greener heating is your goal.
2. Government Heat Pump Grants: Your Wallet’s Best Friend
Grants transform that sticker shock into an obvious upgrade. Here’s what’s on offer in the UK right now.
2.1 Boiler Upgrade Scheme (BUS)
The BUS is a national scheme offering up to £5,000 off the cost of an air source heat pump. It’s a fixed-sum grant—no hassle, no income test. Simple.
2.2 Local Authority Top-Ups
Several councils match or top-up the BUS grant. You could secure an extra £1,000–£2,000 if your region chips in. Check with your local energy office.
2.3 Applying Step by Step
- Choose an MCS-certified installer (like Megawave).
- Complete the BUS application online with your installer’s details.
- Book a survey and final install.
- Claim the grant—paid directly to your installer.
Easy. And you pay the balance over instalments or finance plans.
Rely on expert support to tick every box and beat admin slip-ups.
Around halfway through your planning, you’ll see that grants turn a £10,000 spend into under £5,000 net. Impressive, right? Discover how government heat pump grants power your savings

Upfront cost still a hurdle? Choose a zero-interest, 84-month plan that splits what you owe after grants. Your monthly payment could be less than your old gas bill.
4. Long-Term Savings and ROI
Pump vs boiler. The numbers speak.
4.1 Running Costs vs Traditional Boilers
A gas boiler at 85 % efficiency burns about 15 kWh of gas to produce 12.75 kWh of heat. An air source heat pump at SCOP 3.5 uses just 3.6 kWh of electricity for the same output. That’s a potential 60 % cut in energy consumed.
4.2 Payback Period
Typical payback on an air source heat pump in the UK is 5–7 years, once you include:
- Lower running bills
- Government heat pump grants
- Reduced maintenance costs
Beyond payback, you’re essentially heating for free. Free-ish. Because electricity still costs. But far less than gas.
5. Is It Right for You?
Ask yourself:
- Do you want lower bills and less carbon?
- Does your property suit external units and indoor handlers?
- Are grants and finance options appealing?
If yes, you’re on track. If unsure, book a no-obligation survey.
Conclusion: Ready to Make the Switch?
Air source heat pumps can seem pricey at first. But with grants, smart finance, and eco-upgrades like R290 refrigerant, the numbers add up. You’ll cut bills, cut emissions, and enjoy even home heating—year round.
