Where a radiator falls short, the usual fix is a larger panel radiator, a double or triple-panel model in the same space, or a fan-assisted radiator where wall space is tight. We also check the pipework feeding each radiator, because narrow pipes can restrict the higher water flow rates heat pumps rely on. Everything is listed in a radiator schedule in your quote, so you can see exactly which radiators change and why.
Many older houses in Glasgow and Dunbartonshire still have their original single-panel radiators, so the survey checks each one against the room it heats. For period homes in Glasgow and Dunbartonshire and across Glasgow and Dunbartonshire, column radiators can keep the character of a room while giving enough heat at low temperatures. Extensions and kitchen-diners around Glasgow and Dunbartonshire with large glazed areas get their own radiator calculation.
Who it suits
- Extensions and loft conversions with large areas of glazing
- 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
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a home in Glasgow and Dunbartonshire, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
Heat pump radiators prices in Glasgow and Dunbartonshire
The ranges below are typical installed prices for homes in Glasgow and Dunbartonshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Glasgow and Dunbartonshire can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |

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.
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.
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.
