Gas boiler to heat pump for Craigavon homes
Most homes can run on a heat pump if the system is designed properly, and Craigavon is no different. The key is matching the heat pump and radiators to the home's heat loss.
Semi-detached and terraced houses in Craigavon often have an airing cupboard that can be reused for a heat pump cylinder. Installers in Craigavon take out the old boiler and flue and seal the wall opening as part of the job.
Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.
- Combi owners who can find space for a hot water cylinder
- Boilers that are old, unreliable or due for replacement
- Households ready to give up gas entirely and drop the standing charge
What's included
- Removal of the gas boiler, flue and any loft tanks
- System flush and radiator upgrades where the design calls for them
- Capping of the gas pipe at the boiler position where you are giving up gas
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
Rear gardens and side returns in Craigavon usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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 Craigavon home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
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.

Replacing a gas boiler with a heat pump in Craigavon: questions
How soon can you survey a home in Craigavon?
Survey dates depend on how busy installers are in County Armagh. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Craigavon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Craigavon home states the expected time.
Do I need new radiators for a heat pump in Craigavon?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Craigavon home gives a room-by-room list.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
Is there a grant to replace a gas boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump that replaces a gas boiler, for eligible owners of existing homes. The MCS-certified installer applies to Ofgem and deducts the grant from your quote, and Ofgem contacts you to confirm. Scotland has separate Home Energy Scotland funding, and Northern Ireland has no dedicated homeowner grant at present.
