Before you book: air source heat pump installation in Derry/Londonderry
The question for a Derry/Londonderry home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Homeowners across County Londonderry can arrange a survey in Derry/Londonderry for a room-by-room design and a written quote before committing to anything. Installers working in Derry/Londonderry 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.
- 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
What's included
- MCS registration and certificate, plus network operator notification
- Radiator and pipework changes where the design needs them
- 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 Derry/Londonderry, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in Northern Ireland

Air source heat pump installation in Derry/Londonderry: questions
How long does installation take in Derry/Londonderry?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Derry/Londonderry home states the expected time.
How soon can you survey a home in Derry/Londonderry?
Survey dates depend on how busy installers are in County Londonderry. We offer the next available dates when you enquire and confirm them in writing.
How long does a heat pump survey take in Derry/Londonderry?
A home survey in Derry/Londonderry 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.
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.
