Before you book: replacing a gas boiler with a heat pump in Donaghadee
Homes around Donaghadee range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
If your Donaghadee home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Installers in Donaghadee 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
- System or regular boiler homes with an existing airing cupboard
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- System flush and radiator upgrades where the design calls for them
- Free survey with heat loss calculation and cylinder siting
- Capping of the gas pipe at the boiler position where you are giving up gas
- Removal of the gas boiler, flue and any loft tanks
Many gas-heated homes in Donaghadee have a combi boiler in the kitchen, so the survey starts by finding the right place for a 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 Donaghadee.
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 Donaghadee property at survey.
Guide prices for replacing a gas boiler with a heat pump in Donaghadee

Replacing a gas boiler with a heat pump in Donaghadee: questions
Do you cover Bangor (County Down) as well as Donaghadee?
Yes. We arrange surveys and installation in Bangor (County Down), which is about 5 miles west of Donaghadee, and across County Down.
How soon can you survey a home in Donaghadee?
Survey dates depend on how busy installers are in County Down. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Donaghadee?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Donaghadee home states the expected time.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
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.
