A new-build heat pump is an air-to-water system designed into a home while it is on the drawing board or being built, rather than retrofitted later. Because walls, floors and glazing are being chosen at the same time, heat loss can be calculated from the drawings, and the emitters, pipework and cylinder can be planned for a low flow temperature from day one.
Builders working across Ayrshire can coordinate first and second fix with an installer covering Ayrshire. Plots in Ayrshire with tight boundaries benefit from fixing the outdoor unit position before landscaping is finalised. Self-builders in and around Ayrshire can bring us in at drawing stage so the heat pump, cylinder and pipe routes are designed in from the start.
Who it suits
- Self-builders planning heating alongside the structure
- Replacement dwellings and major conversions treated as new homes
- Architects and builders who want a heat loss design from the drawings
- Small builders and developers working on one-off homes or small groups
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Ayrshire 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.

New-build and self-build heat pumps questions
Where should the outdoor unit go on a new build?
Somewhere with free airflow, a solid base and drainage, away from bedroom windows and boundaries where possible, and positioned to pass the MCS noise assessment. On a new build this can be planned into the landscaping, such as a side return or screened area near the plant room, which keeps pipe runs short. Planning rules differ by nation, so we check the position at design stage.
Do new builds have to have a heat pump?
The rules depend on the nation and when your project was approved, so check with your architect or building control. New homes in England are being built to tighter carbon standards, and Wales, Scotland and Northern Ireland set their own building regulations. A heat pump is one of the main ways new homes meet these standards, and we design the heating to whichever applies.
How long does a new-build heat pump installation take?
It is split across the build. First fix typically takes a few days once the structure is up, and second fix with commissioning takes a few more days near completion. Underfloor heating in screed then follows a gradual drying-out schedule. Exact timing depends on your build programme, which we agree with your builder so trades are not left waiting on each other.
Can a self-build get the Boiler Upgrade Scheme grant?
In some cases. In England and Wales the scheme is aimed at existing homes and most new builds are not eligible, but some self-builds can qualify depending on circumstances, so check eligibility before including a grant in your budget. If the scheme can apply, the MCS-certified installer named in your quote handles the application. Scotland and Northern Ireland are outside the scheme.
