Commercial Heat Pump Costs UK: Installation & Running Costs
Last updated: August 2026
Commercial heat pump costs vary enormously. A relatively simple system for a small commercial property and a multi-unit installation serving a large building can differ not just in equipment capacity, but in electrical work, hydraulics, controls, emitters, hot-water storage, acoustic requirements and professional design costs.
This guide explains what makes up the cost of a UK commercial heat pump project, how to calculate running costs, how current business electricity and gas prices affect the comparison, and what to look for when comparing proposals.

Quick Answer: How Much Does a Commercial Heat Pump Cost?
There is no reliable single average price for a commercial heat pump installation in the UK.
The commercial market ranges from relatively small systems serving shops and offices to modular installations delivering hundreds of kilowatts and large industrial heat pumps serving process-heat applications.
A meaningful commercial budget therefore needs to include the whole installed system, not just the price of the heat-pump unit.
Commercial heat-pump cost = much more than equipment price
A complete project may include heat pumps, hydraulic equipment, storage, emitters, electrical upgrades, controls, building works, acoustic measures, professional design, commissioning and modifications to the existing heating system.
If you are still researching the technology itself, start with our Commercial Heat Pumps UK guide.
Why We Do Not Publish a Generic Commercial Heat Pump Price
Publishing a broad figure such as £X per commercial heat pump installation would create false precision.
Consider the difference between:
- a single heat pump serving a small office;
- four units operating together in cascade;
- a retrofit requiring every major heating coil to be changed;
- a hotel requiring large-volume domestic hot water;
- a new-build commercial property designed around low-temperature heating;
- a ground-source system requiring boreholes;
- and an industrial heat-recovery project producing several hundred kilowatts of process heat.
Even two projects with the same headline heat-pump capacity can have very different installed costs.
Instead of asking only how much a 100kW heat pump costs, ask what the complete system must include to deliver the required heat, cooling and hot water at the building’s design conditions.
What Makes Up a Commercial Heat Pump Installation Cost?
| Cost Area | What It Can Include | Why It Can Vary |
|---|---|---|
| Heat-pump equipment | Outdoor units, compressors, internal modules and manufacturer controls | Capacity, refrigerant, temperature capability and product architecture |
| Hydraulic equipment | Pumps, headers, buffer vessels, expansion equipment, valves and heat exchangers | System volume, number of circuits, flow rates and plant configuration |
| Heat emitters | Radiators, fan coils, underfloor heating and air-handling coils | Existing equipment may not deliver enough heat at the proposed water temperature |
| Hot-water system | Cylinders, calorifiers, thermal storage and heat exchangers | Peak demand, recovery rate and required storage temperature |
| Electrical works | Cabling, distribution boards, isolators and supply upgrades | Existing electrical capacity and heat-pump maximum input |
| Controls | Sequencing, weather compensation, BMS integration and energy monitoring | Building complexity and number of heat-pump modules or heating zones |
| Building works | Concrete bases, steelwork, penetrations, plant enclosures and access works | Equipment size, location and existing building constraints |
| Acoustic treatment | Screens, enclosures and specialist noise mitigation | Proximity to neighbouring properties and noise-sensitive spaces |
| Professional services | Surveys, feasibility, detailed design, planning and project management | Project size, procurement route and technical complexity |
| Commissioning | System balancing, controls setup, testing and performance verification | Number of circuits, plant complexity and monitoring requirements |
Our Commercial Heat Pump Installation, Design & Procurement Guide explains these elements in more detail.
What Affects Commercial Air Source Heat Pump Costs?
Commercial air source heat pumps avoid the boreholes or ground arrays required for ground-source systems, but the outdoor equipment still represents only one part of the cost.
Important variables include:
- Required heating capacity
- Single-unit versus cascade configuration
- Heating-only versus reversible heating and cooling
- Standard versus high-temperature heat-pump equipment
- Refrigerant, including R290 propane systems
- Existing heating-system condition
- Flow temperature
- Emitter upgrades
- Domestic hot-water demand
- Electrical capacity
- Outdoor-unit positioning
- Noise mitigation
- BMS integration
- Craneage and plant access
- Commissioning requirements
Our Commercial Heat Pump Manufacturers UK comparison also shows why equipment specifications can vary significantly between brands and product families.
Does Heat Pump Capacity Determine Installation Cost?
Capacity matters, but installed cost does not increase in a simple straight line with heat-pump output.
A larger project may achieve some economies of scale in equipment and professional costs, while other costs can jump sharply when a project triggers additional electrical infrastructure, structural work, acoustic treatment or major changes to the building’s heat-distribution system.
Two 50kW Units
May require more controls, pipework and electrical connections than one larger unit, but could offer better staging and resilience.
One 100kW Unit
May simplify some infrastructure, but the building becomes more dependent on a single item of plant unless another resilience strategy is provided.
The design decision should therefore be based on load profile, modulation, redundancy, maintenance and system performance as well as capital cost.
New-Build vs Retrofit Commercial Heat Pump Costs
A heat pump designed into a new commercial building can have a very different cost profile from one retrofitted into an existing boiler-heated property.
| New Build | Existing Building Retrofit | |
|---|---|---|
| Emitter design | Can be designed from the outset for lower water temperatures | Existing radiators or coils may need checking or replacement |
| Electrical infrastructure | Can be incorporated into original electrical design | Existing supply may require upgrading |
| Plant location | Can be planned into the building and external layout | May be constrained by existing structures and neighbours |
| Controls | BMS can be designed around the heat-pump system | New equipment may need integrating with legacy controls |
| Heating temperatures | Can often be designed lower from the outset | Existing boiler systems may have historically operated at much higher temperatures |
| Disruption | Installed during construction | Phasing and maintaining building operation can add complexity |
Retrofit does not automatically mean a heat pump is unsuitable. It simply means the existing building and heating system need to form part of the cost assessment.
How to Calculate Commercial Heat Pump Running Costs
The starting point is the amount of useful heat the building actually needs.
Commercial heat-pump running-cost formula
Electricity required = useful heat delivered ÷ seasonal performance factor
Energy cost = electricity required × electricity unit price
For example, if a building needs 100,000kWh of useful heat in a year and the complete heat-pump system achieves a seasonal performance factor of 3:
- 100,000kWh useful heat ÷ 3 = approximately 33,333kWh electricity
- The electricity cost is then calculated using the organisation’s actual contracted electricity rate
Current UK Business Electricity and Gas Prices
The Department for Energy Security and Net Zero publishes official quarterly energy-price statistics for UK non-domestic consumers.
For Quarter 1 2026, January to March, the UK-wide averages including the Climate Change Levy were:
| Energy | Q1 2026 Average Non-Domestic Price | Important Context |
|---|---|---|
| Electricity | 24.14p/kWh | UK non-domestic average including CCL and excluding VAT |
| Gas | 5.17p/kWh | UK non-domestic average including CCL and excluding VAT |
These figures are market averages, not recommended tariff assumptions for an individual project. DESNZ reports different prices across different consumption bands, and many businesses are on fixed contracts negotiated at different times.
Unlike domestic default tariffs, business energy contracts are not protected by Ofgem’s household energy price cap.
Use the organisation’s actual electricity and gas contract prices, including any relevant time-of-use structure and charges. Do not use the domestic Ofgem price-cap rate to model a normal commercial project.
Worked Example: 100,000kWh Annual Heat Demand
The following example shows how strongly seasonal efficiency affects running costs.
It uses:
- 100,000kWh annual useful heat demand
- 24.14p/kWh electricity, using the DESNZ Q1 2026 non-domestic average including CCL
- No standing charges, VAT, maintenance or other project-specific charges
| Seasonal Performance Factor | Electricity Required | Illustrative Annual Energy Cost |
|---|---|---|
| 2.5 | 40,000kWh | £9,656 |
| 3.0 | 33,333kWh | Approximately £8,047 |
| 3.5 | 28,571kWh | Approximately £6,897 |
| 4.0 | 25,000kWh | £6,035 |
| 4.5 | 22,222kWh | Approximately £5,364 |
Commercial Heat Pump vs Gas Boiler Running Costs
A commercial heat pump can be several times more efficient than a boiler at converting purchased energy into useful heat, but electricity is currently considerably more expensive per kWh than gas for the average UK non-domestic consumer.
That means efficiency needs to be considered alongside the electricity-to-gas price ratio.
Using the same Q1 2026 DESNZ averages:
- Electricity: 24.14p/kWh
- Gas: 5.17p/kWh
If an existing gas boiler were assumed to deliver 85% seasonal efficiency, producing 100,000kWh of useful heat would require approximately 117,647kWh of gas.
At 5.17p/kWh, that gives an illustrative fuel cost of approximately £6,082.
Under those particular assumptions, the heat pump would reach approximately the same fuel-only energy cost at a seasonal performance factor of around 4.0.
That does not mean every commercial heat pump needs an SPF of 4
The break-even point changes whenever electricity prices, gas prices, boiler efficiency or operating conditions change. Commercial projects may also replace cooling plant, avoid other fuel costs, recover waste heat or use different electricity contracts, all of which can materially change the comparison.
How to Calculate Your Own Break-Even Efficiency
For a basic comparison with a gas boiler, the approximate fuel-only break-even seasonal performance factor can be calculated as:
Break-even SPF
Electricity unit price × boiler seasonal efficiency ÷ gas unit price
For example:
24.14p × 0.85 ÷ 5.17p = approximately 3.97
This simple calculation is useful for initial screening, but a commercial investment case should go further.
It should also consider:
- Standing and capacity charges
- Time-of-use electricity pricing
- Maintenance costs
- Boiler replacement or avoided boiler investment
- Cooling-system replacement
- Heat recovery
- On-site electricity generation
- Electrical infrastructure
- Capital allowances or other tax treatment where applicable
- Grant support
- Equipment life and replacement assumptions
Why Flow Temperature Can Change Running Costs
Heat-pump running costs are strongly influenced by the temperature lift the refrigeration system has to achieve.
For an air-source heat pump, that means the difference between the outdoor air temperature and the water temperature required by the heating system.
A system serving low-temperature underfloor heating or appropriately sized fan coils can therefore operate under very different conditions from one producing high-temperature water for an existing radiator system.
Lower Flow Temperature
Can reduce the required temperature lift and improve efficiency when the building’s emitters can still meet demand.
Higher Flow Temperature
Can make difficult retrofits possible but may reduce efficiency, increasing electricity consumption.
If a project needs higher water temperatures, compare the engineering benefits and operating implications in our High-Temperature Heat Pumps UK guide.
How R290 Can Affect the Commercial Cost Decision
R290 propane is increasingly used in commercial heat pumps, particularly equipment designed to provide relatively high water temperatures.
The refrigerant itself should not be treated as evidence that a project will automatically be cheaper to buy or run.
The financial comparison should still consider:
- Equipment cost
- Performance at the required conditions
- System capacity
- Safety and siting requirements
- Maintenance strategy
- Expected operating life
Our R290 Heat Pumps UK guide explains propane systems across domestic, commercial and industrial applications.
Commercial Hot-Water Demand Can Change the Economics
Space heating is only one part of the energy bill in many commercial buildings.
Hotels, healthcare facilities, leisure buildings and hospitality businesses can have substantial domestic hot-water demand.
Hot water can affect running costs because it may require:
- Higher water temperatures
- Longer compressor operation
- Large storage volumes
- Legionella-control strategies
- Secondary circulation
- Supplementary heating in some designs
A project should therefore model space heating and hot water separately rather than assuming one seasonal efficiency applies perfectly to both.
Cooling Can Improve the Whole-System Cost Case
A commercial heat-pump project should not always be compared only against the gas boiler it replaces.
Many commercial buildings also operate chillers, split air conditioning or other cooling equipment.
If a reversible commercial heat pump can replace both heating and cooling plant, the investment comparison may need to consider:
- Avoided boiler replacement
- Avoided chiller or air-conditioning replacement
- Heating electricity consumption
- Cooling electricity consumption
- Maintenance of both existing systems
- Potential heat recovery between simultaneous heating and cooling loads
A heat pump providing heating and cooling is performing a different job from a gas boiler providing heating alone.
Can Time-of-Use Electricity Reduce Commercial Heat Pump Costs?
Potentially, but the opportunity depends on the organisation’s electricity contract, building demand and ability to shift heat production.
Thermal storage, building thermal mass and intelligent controls can sometimes allow heat to be produced at more favourable times, but this should be modelled against the actual tariff rather than assumed.
For larger electricity users, the financial model may also need to consider:
- Half-hourly electricity data
- Peak demand
- Capacity charges
- Contracted supply capacity
- Time-of-use rates
- On-site solar generation
- Battery storage
- Other major electrical loads
Historical annual electricity consumption alone may therefore be insufficient for a detailed commercial heat-pump business case.
Maintenance and Whole-Life Cost
Capital cost and annual electricity use are not the only financial considerations.
A whole-life comparison should also include:
- Planned heat-pump servicing
- Filters, strainers and water treatment
- Circulation pumps
- Controls and sensors
- Refrigerant-system maintenance
- Replacement components
- Remote monitoring
- Emergency call-out arrangements
- Expected equipment replacement periods
- Maintenance of retained backup plant
Different commercial heat pump manufacturers also offer different service, commissioning and support arrangements, so purchase price alone does not establish whole-life value.
Can Businesses Get a Grant Towards Commercial Heat Pump Costs?
Some smaller non-domestic properties in England and Wales can qualify for the Boiler Upgrade Scheme.
As of August 2026, the current grant values include:
- £7,500 towards qualifying air-to-water heat pumps
- £7,500 towards qualifying ground-source heat pumps, including eligible water-source systems
- £9,000 for eligible off-gas-grid properties replacing oil or LPG with a qualifying air-to-water or ground-source heat pump, available until 31 March 2027
The £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps is restricted to residential properties.
BUS is designed for homes and smaller non-domestic buildings and has system-capacity and eligibility requirements, so it should not be assumed to apply to a large commercial project.
Commercial Heat Pump Payback: What Should Be Included?
Simple payback is often calculated as:
Simple payback
Additional capital investment ÷ estimated annual financial saving
That can be useful as a screening tool, but larger commercial projects should usually consider a more complete financial assessment.
This can include:
- Capital expenditure
- Grant support
- Annual electricity use
- Fuel displaced
- Maintenance
- Replacement plant that would otherwise be required
- Energy-price assumptions
- Equipment life
- Financing costs
- Residual value
- Discount rate
Larger organisations may therefore compare net present value, internal rate of return or whole-life cost rather than relying solely on a simple payback period.
Common Costs That Can Be Missed From Commercial Heat Pump Quotes

- DNO or electrical-supply work where required
- Radiator or fan-coil upgrades
- Air-handling coil modifications
- Buffer vessels and thermal stores
- Domestic hot-water equipment

- BMS integration
- Energy meters
- Outdoor-unit bases
- Craneage or specialist lifting
- Scaffolding or access equipment
- Acoustic surveys
- Noise mitigation
- Planning work
- Removal of existing plant
- Commissioning
- Operator training
- Post-installation optimisation
Our commercial heat pump procurement guide is designed to help businesses compare these differences before choosing a proposal.
How to Compare Commercial Heat Pump Quotes
The cheapest proposal is not automatically the lowest-cost system over its operating life.
| Ask Each Supplier For | Why It Matters |
|---|---|
| Design heat load | Shows what the equipment is actually being sized to meet |
| Design outdoor temperature | Provides context for available air-source heat-pump capacity |
| Design flow temperature | Has a major influence on emitter output and heat-pump performance |
| Heat-pump output at design condition | More useful than nominal catalogue capacity |
| Annual heat demand | Forms the basis of operating-cost calculations |
| Predicted seasonal efficiency | Allows electricity consumption to be estimated |
| Electricity-price assumption | Allows you to check whether the financial model reflects your actual tariff |
| Hot-water assumptions | Can materially change annual performance |
| Included electrical work | Prevents major infrastructure costs appearing later |
| Commissioning scope | Controls and balancing affect real-world performance |
| Monitoring strategy | Allows predicted and actual performance to be compared |
Check whether both proposals use the same building heat demand, flow temperature, weather data, hot-water requirement, energy prices and system boundaries.
Commercial vs Industrial Heat Pump Costs
Industrial heat-pump economics can be fundamentally different from normal commercial building heating.
An industrial project may recover heat that would otherwise be wasted and upgrade it for use elsewhere in a manufacturing process.
Its financial case can therefore depend on:
- Available waste-heat temperature
- Required process temperature
- Annual operating hours
- Simultaneous heating and cooling value
- Production schedules
- Fuel displaced
- Plant integration
A system operating thousands of hours a year against a stable process load should not be evaluated in the same way as an office heating system with strongly seasonal demand.
See our Industrial Heat Pumps UK guide for the separate process-heat market.
Commercial Heat Pump Cost Checklist
Before approving a commercial heat-pump business case, check that it answers all of the following:
- What is the calculated annual useful heat demand?
- What is the peak design heat load?
- What flow temperature has been assumed?
- What seasonal efficiency has been modelled?
- What evidence supports that efficiency assumption?
- What electricity tariff has been used?
- Has the organisation’s actual commercial energy contract been checked?
- Has hot-water demand been modelled separately?
- Has cooling been included where relevant?
- Are electrical upgrades included?
- Are emitter upgrades included?
- Are controls and BMS integration included?
- Are design and professional fees included?
- Is commissioning included?
- Are maintenance costs included?
- Is available funding shown separately?
- Have future energy-price assumptions been sensitivity tested?
A credible cost model should be reproducible
You should be able to understand how the predicted electricity consumption and financial result were calculated. If the assumptions are hidden, it is difficult to judge whether the projected saving is realistic.

Frequently Asked Questions
How much does a commercial heat pump cost in the UK?
There is no reliable single UK average because commercial projects range from small building systems to large multi-unit and industrial installations. A credible price needs to include the complete system, including equipment, hydraulics, electrical works, controls, emitters, design and commissioning where required.
How do you calculate commercial heat pump running costs?
Divide the building’s useful annual heat requirement by the expected seasonal performance factor to estimate heat-pump electricity consumption, then multiply that electricity use by the organisation’s actual commercial electricity rate.
What is the average UK business electricity price?
DESNZ reported a UK non-domestic average electricity price of 24.14p/kWh including Climate Change Levy for January to March 2026. The figure excludes VAT and varies significantly by consumption size and energy contract, so an individual business should use its actual tariff when modelling a project.
Are commercial heat pumps cheaper to run than gas boilers?
They can be, but not automatically. The result depends particularly on heat-pump seasonal efficiency, electricity and gas prices, boiler efficiency, required flow temperature and the building’s operating profile.
What seasonal efficiency does a commercial heat pump need to beat gas?
There is no fixed number because the break-even point changes with energy prices and boiler efficiency. Using the Q1 2026 UK non-domestic average electricity and gas prices and assuming 85% gas-boiler seasonal efficiency gives a fuel-only break-even heat-pump SPF of approximately 4.0. This is an illustrative calculation rather than a project forecast.
Does a high-temperature commercial heat pump cost more to run?
Higher water temperatures generally increase the temperature lift the heat pump has to achieve, which can reduce efficiency. The actual effect should be checked using manufacturer performance data at the required source and water temperatures.
Can businesses get a grant towards a commercial heat pump?
Some eligible smaller non-domestic properties in England and Wales can use the Boiler Upgrade Scheme. Current grants include £7,500 for qualifying air-to-water or ground-source systems and £9,000 in certain eligible off-gas-grid oil or LPG replacement cases until 31 March 2027.
Is the cheapest commercial heat pump quote the best?
Not necessarily. Two quotations may contain different assumptions and scopes. Compare heat load, flow temperature, seasonal performance, equipment output at design conditions, electrical work, emitters, controls and commissioning before comparing headline price.
