Heat pump radiators for Derry/Londonderry homes
In Derry/Londonderry, 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.
In Derry/Londonderry, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Extensions and kitchen-diners around Derry/Londonderry with large glazed areas get their own radiator calculation.
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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
What's included
- Balancing every radiator so each room heats evenly
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
We plan radiator upgrades in Derry/Londonderry so floorboards are lifted only where pipework genuinely needs changing.
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 Derry/Londonderry 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 Derry/Londonderry property at survey.
What to budget for heat pump radiator upgrades in Derry/Londonderry
The ranges below are typical installed prices for homes in County Londonderry, including VAT. A survey sets the exact figure, because two similar-looking houses in Derry/Londonderry can need quite different radiators and pipework.

| Upgrade of about 10 radiators | £1,950–£4,850 |

Installed, inc VAT. The survey lists which radiators need changing.

Heat pump radiator upgrades in Derry/Londonderry: questions
Do I need new radiators for a heat pump in Derry/Londonderry?
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 Derry/Londonderry home gives a room-by-room list.
Where would the outdoor unit go on a Derry/Londonderry 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 Derry/Londonderry home.
How long does installation take in Derry/Londonderry?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Derry/Londonderry home states the expected time.
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.
