Before you book: heat pump radiator upgrades in Lockerbie
The question for a Lockerbie home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
We plan radiator upgrades in Lockerbie so floorboards are lifted only where pipework genuinely needs changing. In Lockerbie, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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.
- 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
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Room-by-room heat loss figures for every heated room
- Pipework checks and any agreed pipe upgrades
- 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
Radiator fitting in Lockerbie is scheduled with your heat pump installation so the system is drained only once.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Lockerbie 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 Lockerbie property at survey.
Heat pump radiators costs around Lockerbie
These are guide prices for Dumfries and Galloway, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £260–£460 |
| Upgrade of about 10 radiators | £2,050–£5,100 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,550–£3,550 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Lockerbie?
On the shortest day Lockerbie gets only about 7 hours 08 minutes of daylight and the noon sun sits around 11° 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.

- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Lockerbie: questions
Do you cover Annan as well as Lockerbie?
Yes. We arrange surveys and installation in Annan, which is about 10 miles south-east of Lockerbie, and across Dumfries and Galloway.
Do I need new radiators for a heat pump in Lockerbie?
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 Lockerbie home gives a room-by-room list.
Can you service a heat pump in Lockerbie that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lockerbie, whoever fitted them. Tell us the make and model when you book.
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.
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.
