What to know about heat pump radiator upgrades in Antrim
In Antrim, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
We plan radiator upgrades in Antrim so floorboards are lifted only where pipework genuinely needs changing. In Antrim, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
- Pipework checks and any agreed pipe upgrades
- Draining, refilling, cleaning and inhibitor treatment of the heating system
Extensions and kitchen-diners around Antrim with large glazed areas get their own radiator calculation.
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 Antrim.
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 Antrim property at survey.
Heat pump radiators prices in Antrim
These are guide prices for County Antrim, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £240–£440 |
| Upgrade of about 10 radiators | £1,950–£4,850 |

Installed, inc VAT. The survey lists which radiators need changing.
Designing for Antrim's winters
On the shortest day Antrim gets only about 7 hours 13 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
From survey to switch-on in Antrim
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Antrim; the surveyor measures rooms, windows and radiators and looks at cylinder space.

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Antrim: questions
Do I need new radiators for a heat pump in Antrim?
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 Antrim home gives a room-by-room list.
Do you cover Ballyclare as well as Antrim?
Yes. We arrange surveys and installation in Ballyclare, which is about 8 miles north-east of Antrim, and across County Antrim.
Where would the outdoor unit go on an Antrim 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 Antrim home.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
