Help with air source heat pump installation in Cornwall
The outdoor appliance is only one part of a new system. Room heat losses, radiator output and hot water demand determine the equipment and alterations needed for the house.
Homeowners in Cornwall can describe the work once to request local quotations. Up to four independent specialists may provide quotations, depending on coverage and availability. You are free to decline them.
What prompts an enquiry in Cornwall
The following situations can be a useful starting point for discussing the work.
- The current boiler is becoming unreliable and you want to plan its replacement.
- You want to explore a wet heating system instead of the storage heaters already fitted.
- A renovation offers access for new pipework, larger radiators or underfloor heating.
- You need enough detail to compare a heat pump proposal with your other heating options.
Checks and tasks to include
- Measure rooms, glazing and insulation, then calculate room-by-room heat losses.
- Work out which emitters can stay and which pipes or radiators need alteration.
- Set out cylinder capacity, outdoor siting, power supply and condensate arrangements.
- Protect floors, install equipment and arrange safe removal of the redundant heating system.
- Test the completed installation, record settings and show the household how to adjust heating and hot water.
Ask why a buffer vessel or volumiser is included if one is proposed. These serve different purposes and should follow the hydraulic design. Microbore pipework needs assessment of flow and pressure loss; its presence does not automatically mean a full repipe. The cylinder must suit the heat pump and household demand, including bath use and recovery time.
Disconnection of an existing gas boiler needs a Gas Safe registered engineer competent for that work. The HSE homeowner guidance explains the registration requirement. Agree who provides electrical and cylinder certification where required.
Compare the scope and the price
The indicative UK guide is £7,000–£14,000. Before grants. Cylinder size, emitter changes, electrical upgrades, pipe runs and making good can move the price substantially; extensive retrofits may exceed the guide.
These figures are not measured local averages for Cornwall. Confirm VAT, travel, materials and any excluded work before comparing totals.
A quotation should separate the appliance from cylinder, radiator and electrical alterations.
Details worth gathering first
Give the current fuel, property type, approximate floor area, insulation improvements and number of occupants. Mention extensions, underfloor heating, cylinder space and difficult side access. Photographs of radiators and the proposed outdoor position help with initial discussions, but cannot replace the final design checks.
Rules and practical checks
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.
For property-specific local guidance, contact Cornwall Council. The council cannot confirm an individual contractor’s availability or guarantee funding.
What to confirm with your chosen firm
Agree the heating and hot water shutdown before work starts. Ask for heat-loss calculations, emitter schedules, commissioning records, applicable certificates and warranty registration. Confirm who handles first-winter adjustments and what the service schedule requires.
The site’s indicative timeframe is 2–5 days. Ask what can be completed within that period and what depends on a later visit.
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.

Questions about air source heat pump installation in Cornwall
These answers cover common decisions before a visit.
Can I request air source heat pump installation quotes in Cornwall?
You can send a free enquiry with the property postcode and the work required. Up to four independent specialists may quote, subject to coverage in Cornwall and availability. Sending the form does not book work or require you to accept a quotation.
Will every radiator need replacing?
No. The designer should compare each radiator’s output at the proposed water temperature with the room’s heat loss. Some may remain, while others need increasing or changing.
Can an older house use a heat pump?
Possibly. Building age alone does not decide suitability. Heat loss, insulation, emitter capacity, available space and the proposed running costs need to be assessed together.
Does a grant cover the whole installation?
Not necessarily. Ask for the full installed price, the confirmed grant deduction and your remaining contribution as separate figures. Additional work may sit outside the main installation price.
