Before you book: heat pump radiator upgrades in Dumbarton
Every property in Dumbarton is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Many older houses in Dumbarton still have their original single-panel radiators, so the survey checks each one against the room it heats. Radiator fitting in Dumbarton is scheduled with your heat pump installation so the system is drained only once.
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 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
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- A radiator schedule showing which radiators stay, which change and their outputs
We plan radiator upgrades in Dumbarton so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Dumbarton 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 Dumbarton property at survey.

- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Dumbarton: questions
What size heat pump does a Dumbarton home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Dumbarton home.
Do you cover Alexandria as well as Dumbarton?
Yes. We arrange surveys and installation in Alexandria, which is about 3 miles north of Dumbarton, and across Glasgow and Dunbartonshire.
How long does a heat pump survey take in Dumbarton?
A home survey in Dumbarton usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
