As energy efficiency becomes a growing priority, more businesses and homeowners are turning to Air Source Heat Pumps (ASHPs) for heating and hot water solutions.
ASHPs offer an environmentally friendly and cost-effective alternative to fossil fuel systems, but one question remains top of mind: What is the ASHP installation cost?
Whether you’re planning a domestic upgrade or a full-scale commercial heating project, understanding the costs involved in ASHP installation is crucial.
Explore the key factors that impact pricing for both residential and commercial systems.
What Affects ASHP Installation Cost?
System Size and Capacity
Domestic: For residential properties, system size is based on square footage, insulation quality, and existing heating systems.
Commercial: Larger spaces require higher-capacity units or multiple heat pumps. Commercial systems are also more likely to include complex zoning requirements and custom controls, which can increase costs.
Property Type and Layout
Domestic: Bungalows, flats, and multi-storey homes all have different design needs, which impact the type and placement of the heat pump.
Commercial: Office buildings, warehouses, schools, and retail spaces each have unique layouts that can complicate installation and increase the time and labour involved.
Heating Distribution System
Domestic: Some installations require upgraded radiators or underfloor heating to accommodate the lower operating temperature of ASHPs.
Commercial: Businesses may need to integrate ASHPs with existing HVAC systems, or replace them entirely, depending on the building’s use and occupancy.
Accessibility and Site Conditions
For both settings, limited access to the building or outdoor installation space can affect the complexity, and cost, of the project.
Controls and Monitoring
Commercial installations often require advanced building management systems (BMS) for zone control and efficiency tracking, which adds to the cost. In domestic settings, simpler smart thermostats may suffice.

The Importance of a Site Survey
There’s no universal answer to your installation cost without an initial property survey. Every building is different, and a survey helps determine:
The appropriate system size
Integration with your current heating
Energy usage and insulation levels
Whether upgrades or alterations are needed
Your first step is to book a professional survey. This will give you a tailored estimate for your project and ensure maximum system efficiency once installed.
Use Our ASHP Cost Calculator to Estimate Your Savings
Before committing to a full quote, it’s worth understanding the potential savings and benefits of installing an air source heat pump. That’s where our free ASHP cost calculator comes in.
This easy-to-use tool helps both homeowners and business owners get a clear picture of what to expect financially and environmentally when making the switch to a heat pump.
For example, the calculator shows that when installing a standard ASHP in an average-sized four-bedroom detached home, you could save anywhere between £415 and £3,400 per year – a significant reduction depending on your current system and energy prices.
These savings aren’t just limited to homes. For businesses, especially those operating larger or older premises, the long-term reduction in heating bills can be even more substantial.
The calculator also estimates how much CO₂ you could cut annually, supporting sustainability initiatives and helping you make a more informed decision.
In just a few minutes, you can gain real insight into how a heat pump could impact your finances and carbon footprint, even before speaking to an installer. It’s the perfect first step if you’re exploring whether an ASHP is right for your home or commercial property.
How to Reduce ASHP Installation Cost
If you’re a homeowner in England or Wales, you may be eligible for the Boiler Upgrade Scheme. This government grant offers up to £7,500 towards your air source heat pump installation.
Key points about the BUS grant:
Available for domestic properties in England and Wales
Operates on a first-come, first-served basis
Only applies to properties with an EPC (Energy Performance Certificate) and no recent recommendations for loft or cavity wall insulation
As your installer, we’ll apply for the grant on your behalf
The £7,500 will be deducted from your upfront cost
You only pay the remaining balance of the installation
This makes ASHPs significantly more affordable for many homeowners, and it also accelerates the switch to renewable heating.
