What to know about heat pump radiator upgrades in Bonnyrigg
Most homes can run on a heat pump if the system is designed properly, and Bonnyrigg is no different. The key is matching the heat pump and radiators to the home's heat loss.
Many older houses in Bonnyrigg still have their original single-panel radiators, so the survey checks each one against the room it heats. Extensions and kitchen-diners around Bonnyrigg with large glazed areas get their own radiator calculation.
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.
- 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
- Extensions and loft conversions with large areas of glazing
What's included
- 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
- Supply and fitting of new radiators, valves and brackets
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
Radiator fitting in Bonnyrigg 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 Bonnyrigg 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.
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 radiator upgrades in Bonnyrigg: questions
How long does installation take in Bonnyrigg?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Bonnyrigg home states the expected time.
Where would the outdoor unit go on a Bonnyrigg house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Bonnyrigg home.
How soon can you survey a home in Bonnyrigg?
Survey dates depend on how busy installers are in Edinburgh and the Lothians. We offer the next available dates when you enquire and confirm them in writing.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
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.
