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.
In Stirling, Falkirk and Clackmannanshire, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Many older houses in Stirling, Falkirk and Clackmannanshire still have their original single-panel radiators, so the survey checks each one against the room it heats. Radiator fitting in Stirling, Falkirk and Clackmannanshire is scheduled with your heat pump installation so the system is drained only once.
Who it suits
- Extensions and loft conversions with large areas of glazing
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Stirling, Falkirk and Clackmannanshire can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your property at survey.

Heat pump radiator upgrades questions
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.
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 radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
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.
