Air source heat pump installation for Falmouth homes
Every property in Falmouth is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Many homes in Falmouth have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. Installers working in Falmouth plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
For older properties in Falmouth, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
Grants and rules for heat pumps in England
Homes in Falmouth can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
Air source heat pump installation costs around Falmouth
The ranges below are typical installed prices for homes in Cornwall, including VAT. A survey sets the exact figure, because two similar-looking houses in Falmouth can need quite different radiators and pipework.

How long is the heating season in Falmouth?
On the shortest day Falmouth gets about 8 hours 03 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Falmouth: questions
How soon can you survey a home in Falmouth?
Survey dates depend on how busy installers are in Cornwall. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Falmouth home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Falmouth home.
How long does installation take in Falmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Falmouth home states the expected time.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
