Air source heat pump installation in Helston: what to expect
Most homes can run on a heat pump if the system is designed properly, and Helston is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers working in Helston plan the order of work so heating and hot water are off for as short a time as practical. Homeowners across Cornwall can arrange a survey in Helston for a room-by-room design and a written quote before committing to anything.
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.
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- Removal of the old boiler or heaters
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- Commissioning, handover and a walk-through of the controls
For older properties in Helston, 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
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Helston quote.
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.
What to budget for air source heat pump installation in Helston
Guide prices for Helston and the rest of Cornwall are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

Winter daylight and heating in Helston
On the shortest day Helston 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 steps for air source heat pump installation in Helston
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Helston home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Helston: questions
What size heat pump does a Helston 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 Helston home.
Do you cover Camborne as well as Helston?
Yes. We arrange surveys and installation in Camborne, which is about 8 miles north of Helston, and across Cornwall.
Where would the outdoor unit go on a Helston house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Helston home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
