The good news is that many homes keep most of their existing radiators. Older houses were often fitted with radiators larger than they needed, and rooms that have since been insulated may now need less heat. The only way to know is a room-by-room calculation: the heat loss survey works out how much heat each room loses on a cold day and checks whether the radiator already there can deliver it at the chosen flow temperature.
Extensions and kitchen-diners around County Armagh with large glazed areas get their own radiator calculation. Many older houses in County Armagh still have their original single-panel radiators, so the survey checks each one against the room it heats. For period homes in County Armagh and across County Armagh, column radiators can keep the character of a room while giving enough heat at low temperatures.
Who it suits
- Homeowners who want the lowest practical flow temperature for efficiency
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
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 home in County Armagh 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 property at survey.

Heat pump radiator upgrades questions
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.
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.
Do I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
