Air source heat pump installation for Larne homes
In Larne, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Terraced streets in Larne often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Installers working in Larne 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.
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
In Larne, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Larne home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your Larne property at survey.

Winter daylight and heating in Larne
On the shortest day Larne gets only about 7 hours 12 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

Air source heat pump installation in Larne: questions
How soon can you survey a home in Larne?
Survey dates depend on how busy installers are in County Antrim. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Larne?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Larne home states the expected time.
How long does a heat pump survey take in Larne?
A home survey in Larne usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
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.
