What's Included in Our Air Source Heat Pump Installation Service?

Air Source Heat Pump Installation for Existing Homes

Many homeowners install heat pumps when replacing an ageing gas boiler or other traditional heating system.

Air-to-water heat pumps work by extracting energy from the outside air and transferring it into your home's heating and hot water system. Unlike a gas boiler, a heat pump doesn't generate heat by burning fuel.

The installation may include a new heat pump unit, hot water cylinder, heating controls and radiator upgrades. Your installer checks the existing pipes and heating equipment to identify which components can be retained.

Heat Pumps for Rural and Off-Gas Properties

Many rural homes in Cornwall have no mains gas connection and rely on oil, LPG or electric heating.

Installing a heat pump can provide an alternative to these systems while reducing reliance on fossil fuels. A correctly designed system may also help lower your home's carbon footprint, although actual savings depend on electricity prices and system performance.

Older stone properties may need additional insulation or new radiators to provide efficient heating at a lower temperature.

Real-World Example: Replacing Storage Heaters in an Older Home

In our latest homeowner case study, a resident of an 1890s three-bedroom terraced house replaced expensive electric storage heaters with an air source heat pump. After five years of use, they reported a warmer, more comfortable home, lower heating costs and reliable performance even when outdoor temperatures reached -18°C.

Their experience highlights how installing a heat pump can benefit older properties, although actual performance and energy savings depend on insulation, system design and the heating being replaced.

Heat Pumps for Renovations and New Builds

Planning a renovation or building a new home? Installing a heat pump early in the project makes it easier to plan the outdoor unit location, indoor components, pipework and hot water cylinder.

Underfloor heating is particularly suitable for heat pumps because it can distribute heat efficiently at lower flow temperatures.

A new system can also work alongside solar panels and compatible smart controls, helping homeowners make better use of renewable energy generated at home.

Our Three-Step Heat Pump Installation Process

Step 1: Home Survey and Heat Loss Assessment

Before installing a heat pump, your installer needs to understand how much energy your property requires to stay warm.

A home energy assessment examines insulation, windows, existing heating equipment and hot water demand. Room-by-room heat loss calculations help determine the correct heat pump capacity and identify any necessary improvements.

The survey also considers:

  • Outdoor space for the external unit and suitable airflow.

  • Existing radiators, pipework and underfloor heating.

  • Space for a hot water cylinder.

  • Electricity supply and any electrical upgrades.

  • Noise, property boundaries and planning restrictions.

A thorough heat loss assessment is essential for selecting the right heat pump and ensuring the heating system operates efficiently.

Step 2: Installing Your New Heat Pump System

Once the design is agreed, your heat pump installer arranges the installation date and explains what to expect.

The installation process generally involves positioning the outdoor heat pump unit, connecting the heating pipework, fitting or adapting the hot water cylinder and installing suitable controls.

The external unit may be mounted on a suitable base or wall-mounted brackets, depending on the equipment and property. Existing pipes and radiators are retained where practical, with upgrades carried out where necessary.

Electrical connections are completed by appropriately qualified professionals.

How much disruption you experience will vary depending on the work required. Your installer should explain any expected interruption to heating and hot water before installation day.

Step 3: Commissioning, Certification and Handover

Once your new heat pump is installed, the system is tested and configured for efficient operation.

Commissioning includes checking flow temperatures, heating controls, hot water performance and system safety. Correct settings help ensure the heat pump operates efficiently without unnecessary electricity consumption.

The MCS-certified installer manages the relevant certification and documentation, following applicable industry standards.

You'll also receive guidance on operating your new system, adjusting heating schedules and maintaining optimal performance.


Air Source Heat Pump Installation Costs and Government Grants

The cost of installing a heat pump in Cornwall will vary depending on property size, heating requirements and any additional work needed. A quotation may include the heat pump unit, hot water cylinder, new radiators, electrical upgrades, controls and installation labour.

Boiler Upgrade Scheme Funding

Eligible homeowners in England can currently receive £7,500 towards an air-to-water heat pump through the Boiler Upgrade Scheme.

Qualifying off-gas-grid properties replacing oil or LPG heating may receive an increased grant of £9,000 for eligible applications during the current enhanced-grant period ending 31 March 2027.

Your MCS-certified installer manages the grant application, with approved funding deducted from the installation quotation.

Qualifying domestic installations also currently benefit from 0% VAT until 31 March 2027.

Heat Pump Installation: Three Useful Facts

99% of Recorded Retrofit Installations Were Air-to-Water Systems

Government figures show that air-to-water systems accounted for 99% of recorded UK retrofit heat pump installations during the first half of 2026.

This type of heat pump supplies central heating and domestic hot water, making it suitable for many properties replacing traditional boilers.

The South West Accounted for 14% of UK Retrofit Installations

During the same period, 14% of recorded UK retrofit heat pump installations took place in the South West.

This demonstrates the growing role of heat pumps in the region's transition towards more energy-efficient, low-carbon heating.

Heat Pumps Can Reduce Heating Carbon Emissions by Up to 70%

Government guidance states that heat pumps can reduce heating-related carbon emissions by up to 70% compared with gas boilers.

Actual reductions depend on electricity generation, the system being replaced and how efficiently the heat pump operates.

Preparing Your Cornwall Home for Heat Pump Installation

Insulation and Energy Efficiency

Good insulation helps your home retain heat, improving comfort and reducing the amount of energy needed for heating.

Older Cornish properties may benefit from loft insulation, draught-proofing or other improvements before installation.

Your installer can assess the property and explain which upgrades could improve efficiency.

Radiators and Underfloor Heating

Heat pumps generally work most efficiently at lower water temperatures than traditional boilers.

Some existing radiators may be suitable, while others may need replacing with larger models to provide enough heat.

Underfloor heating can also be an effective option, particularly for new builds and major renovations.

Outdoor Unit Positioning and Electrical Supply

The outdoor heat pump unit needs sufficient airflow and a suitable position that considers access, noise and neighbouring properties.

In coastal Cornwall, exposure to salt air and prevailing winds may influence equipment selection and positioning.

Your installer also checks the electricity supply and arranges any necessary network notifications or approvals.
