Air source heat pump installation is the full job of replacing your heating with an air-to-water system: a survey and room-by-room heat loss calculation, the outdoor unit, a hot water cylinder, controls, any radiator or pipework changes, commissioning and registration. A heat pump takes heat from the outside air using a refrigerant cycle and delivers it to your radiators or underfloor heating and to a cylinder of stored hot water. In a well-designed system it typically produces about 3–4 units of heat for every unit of electricity it uses.
In County Fermanagh, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Installers working in County Fermanagh plan the order of work so heating and hot water are off for as short a time as practical. Many homes in County Fermanagh have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Who it suits
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
Grants and rules for heat pumps in Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in County Fermanagh.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.

Air source heat pump installation questions
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.
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.
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.
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.
