How Much Does an Air-Source Heat Pump Cost After Grants
Introduction
Air-source heat pumps are increasingly popular in the UK as homeowners transition to renewable energy. Thanks to government schemes like the Boiler Upgrade Scheme (BUS), the upfront cost has become far more manageable. But exactly how much will you pay after grants? This guide breaks it down with realistic examples, savings calculations, and expert tips, so you can plan your installation confidently.
What Is an Air-Source Heat Pump?
Air-source heat pumps extract heat from the outside air to warm your home. They can significantly reduce energy bills compared to traditional gas boilers, especially when paired with proper insulation or renewable energy systems.
Benefits:
- Reduced carbon footprint
- Eligible for government grants
- Long-term energy savings
- Quiet and low-maintenance operation

Average Cost of Installation Before Grants
The cost of an air-source heat pump depends on your home size and system type:
| Home Size | Typical Cost (GBP) | Notes |
| Small (<80m²) | £7,000–£10,000 | Standard single-unit installation |
| Medium (80–150m²) | £10,000–£15,000 | May require multiple units |
| Large (>150m²) | £15,000–£27,500 | Complex installation or hybrid system |
Transition: While these numbers may seem high, grants can reduce the out-of-pocket expense significantly.

Example Cost Breakdown
Let’s take a medium-sized UK home with a £12,000 air-source heat pump installation:
| Item | Cost (GBP) |
| Installation | £12,000 |
| Boiler Upgrade Scheme Grant | -£7,000 |
| VAT Reduction | -£600 |
| Final Cost to Homeowner | £4,400 |
Tip: Always check with installers for exact grant eligibility — some may include application help in their quotes.
How Much Can You Save on Bills?
Average savings depend on current heating costs:
| System | Annual Energy Cost (GBP) | Annual Savings (GBP) |
| Gas Boiler | £1,800 | – |
| Air-Source Heat Pump | £900 | £900 |
Transition: Over time, the initial investment can be offset by reduced energy bills — usually within 5–8 years depending on usage.
FAQs
Q1: Are all homes eligible for the Boiler Upgrade Scheme?
A1: No, eligibility depends on existing heating type, home size, and location.
