Heat pump radiators in Lisburn: what to expect
Homes around Lisburn range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Radiator fitting in Lisburn is scheduled with your heat pump installation so the system is drained only once. Many older houses in Lisburn still have their original single-panel radiators, so the survey checks each one against the room it heats.
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.
- Extensions and loft conversions with large areas of glazing
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
Extensions and kitchen-diners around Lisburn 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 Lisburn.
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 Lisburn property at survey.
Heat pump radiators prices in Lisburn
Guide prices for Lisburn and the rest of County Antrim are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £240–£440 |
| Upgrade of about 10 radiators | £1,950–£4,850 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,450–£3,400 |
Installed, inc VAT. The survey lists which radiators need changing.
Designing for Lisburn's winters
On the shortest day Lisburn gets only about 7 hours 16 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.

Heat pump radiator upgrades in Lisburn: questions
What size heat pump does a Lisburn 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 Lisburn home.
Can you service a heat pump in Lisburn that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lisburn, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Lisburn 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 Lisburn home.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
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.
