Understand the work behind an air source heat pump price
A heat pump price only means much when you know what it includes. The outdoor unit, cylinder, radiator changes, electrical work and commissioning can all appear in one total, or be priced separately. Air Source Heat Pump Cost helps you compare quotations and ask the questions that make those differences clear.
Air Source Heat Pump Cost is a consumer matching service. One online enquiry can bring up to four quotations from independent local specialists, depending on the work, coverage and availability. We do not carry out the work or employ the specialists. Companies joining the network are asked to provide relevant insurance details and references.
Choose the help you need
- Air Source Heat Pump Installation — A first heat pump installation brings together the outdoor unit, hot water storage, heating emitters and controls. The aim is to supply each room with enough heat at the chosen water temperature, rather than simply replace a boiler with a box of similar rated output.
- Air Source Heat Pump Replacement — Replacing an existing air source heat pump starts with finding out what the old system got right and what needs changing. A new outdoor unit may be able to use the cylinder and emitters already fitted, but compatibility and condition need checking before they are retained.
- Air Source Heat Pump Servicing — A heat pump service is a planned inspection and maintenance visit following the manufacturer’s schedule. It checks the outdoor appliance, water circuit and controls, with a written record of readings and any work needed. Repairs discovered during a service may be quoted separately.
- Air Source Heat Pump Repairs — Heat pump repairs start with diagnosis. A cold house or an error code can come from the controls, water circulation, electrical supply or the refrigerant circuit. An engineer needs to identify the cause before recommending parts or deciding whether replacement makes more sense.
- Air Source Heat Pump Grants and Funding — Heat pump funding can reduce the amount a homeowner pays for an eligible installation. It does not remove the need for a suitable design or a clear quotation. The grant scheme, property circumstances and existing heating determine what help may be available.
- Air Source Heat Pump Surveys and Quotes — A heat-loss survey measures how much heat each room needs in winter and checks how a heat pump could supply it. It should lead to usable design information, rather than just a headline unit size or a sales estimate based on bedroom count.
From outdoor air to comfortable rooms
An air-to-water heat pump collects heat from outside and uses electricity to raise its temperature for a wet heating system. It can supply radiators or underfloor heating and heat stored hot water. This site’s installation and grant price guides concern these systems; air-to-air heating has different equipment, uses and funding rules.
A well-designed system needs enough emitter capacity at its chosen flow temperature. That may mean larger radiators in some rooms, better control of underfloor circuits or pipework alterations. It does not follow that every radiator must go. Ask for a room-by-room schedule showing the calculation behind each change.
Plan the indoor space as well as the outdoor unit
The outdoor position needs airflow, service access and an appropriate condensate route. Noise and neighbouring windows should be considered early. Indoors, allow for a suitable cylinder if the design needs one, its pipework and space for maintenance. The electrical supply also needs assessment.
Ask why any buffer vessel, volumiser or additional pump has been specified. The answer should relate to the system design and the manufacturer’s requirements. A smaller equipment list is not automatically better, and extra components should not be included without a reason.
Keep installation costs and running costs separate
Our first-installation budget guide is £7,000–£14,000 before grants, with complex projects potentially higher. The full cost table explains all six service ranges. Running costs depend on heat demand, seasonal performance, controls, hot water use and your electricity tariff. Lower bills compared with your current system are not guaranteed.
For a meaningful running-cost estimate, ask the installer to state the tariff and performance assumptions. Discuss insulation improvements and the effect of different design flow temperatures before choosing equipment. The Energy Saving Trust heat pump guidance provides useful background alongside a property-specific assessment.
Funding and permissions
The Boiler Upgrade Scheme in England and Wales currently offers £7,500 towards an eligible air-to-water heat pump. An additional £1,500 is available until March 2027 for eligible properties heated by oil or LPG with no mains gas connection. Check the current Boiler Upgrade Scheme grant amounts before budgeting. The installer must confirm eligibility; the grant is not available for replacing an existing low-carbon heating system.
Planning rules vary between UK nations and depend on the property and proposed unit. Do not assume an existing heat pump position or a neighbour's installation gives permission for yours. Check siting, noise, listed-building restrictions and any freeholder consent before ordering. Building Regulations and any required electrical or unvented-cylinder certification must be dealt with separately; MCS certification alone is not a blanket building-control approval. Read the Planning Portal guidance for air source heat pumps in England and confirm the position for your UK nation and property.
Have a useful first conversation
- Say what heats the house now and whether it is still working.
- Describe the property, planned alterations and any rooms that struggle to stay warm.
- For an existing heat pump, provide the model, age, service history and exact fault code if there is one.
- Ask whether a proposed visit is free, chargeable or credited against later installation.
