Air source heat pump installation in Bonnyrigg: what to expect
In Bonnyrigg, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Terraced streets in Bonnyrigg often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Installers working in Bonnyrigg plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
What's included
- Free home survey and room-by-room heat loss calculation
- Removal of the old boiler or heaters
- Commissioning, handover and a walk-through of the controls
- System design, unit sizing and a written quote
- Outdoor unit, hot water cylinder and weather compensation controls
For older properties in Bonnyrigg, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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.

Air source heat pump installation 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.
Do I need new radiators for a heat pump in Bonnyrigg?
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 Bonnyrigg home gives a room-by-room list.
What size heat pump does a Bonnyrigg 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 Bonnyrigg home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
