Before you book: replacing a gas boiler with a heat pump in Limavady
Every property in Limavady is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Many gas-heated homes in Limavady have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Rear gardens and side returns in Limavady usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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.
- Boilers that are old, unreliable or due for replacement
- System or regular boiler homes with an existing airing cupboard
- Households ready to give up gas entirely and drop the standing charge
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Capping of the gas pipe at the boiler position where you are giving up gas
Semi-detached and terraced houses in Limavady often have an airing cupboard that can be reused for a heat pump cylinder.
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 Limavady 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 Limavady property at survey.

Replacing a gas boiler with a heat pump in Limavady: questions
What size heat pump does a Limavady home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Limavady home.
Where would the outdoor unit go on a Limavady house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Limavady home.
How long does installation take in Limavady?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Limavady home states the expected time.
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.
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.
