Heat Pump Installers Edinburgh: Planning and Grants

Scottish permitted development lets most homeowners fit one air source heat pump without planning permission. But those rights do not apply inside a World Heritage Site or within the curtilage of a listed building. Edinburgh's Old and New Towns form a World Heritage Site, so homes there need planning permission for an outdoor unit.

Elsewhere, conservation areas cover large parts of the city, from Marchmont and Morningside to Portobello. In those, a heat pump stays within permitted development only if it is at ground floor level on the back of the building.

Edinburgh at a glance

Homes that are flats: 63.2% of Edinburgh households live in a flat, maisonette or apartment, against 34.4% across Scotland. Source
How homes are heated: 79.0% of Edinburgh households use mains gas central heating and 10.2% electric. 3.3% (about 7,900 homes) have no central heating, and oil heats just 0.2%. Source
Age of homes: Only 57% of Edinburgh dwellings were built after 1945, the joint lowest share in Scotland with Glasgow (72% nationally). Source
Heat pump planning: Scottish permitted development for an air source heat pump does not apply within a World Heritage Site or the curtilage of a listed building. In a conservation area the unit must be at ground floor level on the rear elevation. Source
Heat pump grant: Home Energy Scotland offers homeowners up to £7,500 in grant towards a heat pump plus an optional interest-free loan of up to £7,500. The Boiler Upgrade Scheme does not cover Scotland. Source
Energy ratings: 60% of homes in Edinburgh were rated EPC A, B or C (SAP 2012) in 2022 to 2024, so about 40% were D or below. The Scottish average was 55%. Source

Flats and tenements

With 63.2% of households in flats, many Edinburgh enquiries come from tenement owners. The outdoor unit has to go somewhere: a back green, a rear wall bracket or a flat roof. Each needs the agreement of the other owners if it touches common property, and back greens are often shared.

Some blocks are better suited to a shared system serving every flat, which needs all the owners to act together.

Old walls, bigger radiators

Only 57% of Edinburgh dwellings were built after 1945, so solid stone walls are common. A heat pump runs best at low water temperatures, which can mean larger radiators in rooms with high ceilings. Your MCS installer must base the design on a room-by-room heat loss survey.

Grants in Scotland

The Boiler Upgrade Scheme does not cover Edinburgh. Homeowners apply instead to the Home Energy Scotland Grant and Loan, which offers up to £7,500 in grant and an optional interest-free loan of up to £7,500. Insulation can be funded alongside it.

Edinburgh homes and what they need

Stone tenement flats

Planning, common property and space for a hot water cylinder are the three hurdles. Talk to neighbours early and ask the installer about compact cylinders.

Interwar and postwar suburban semis

Outside the conservation areas, these are the most straightforward heat pump homes in Edinburgh: a garden, cavity walls and room for a cylinder.

Georgian and Victorian main-door flats and townhouses

Many are listed or in the World Heritage Site, so planning permission and possibly listed building consent come first. Expect the process to take months.

Areas covered

Engineers who cover Edinburgh work across areas including Leith, Morningside, Marchmont, Bruntsfield, Stockbridge, Portobello, Corstorphine, Gorgie, Musselburgh and Dalkeith.

Questions people in Edinburgh ask

Is planning permission likely to be refused?

Not necessarily. A unit hidden at the back, away from public view, has a better chance. Ask the installer to include photos and noise data in the application.

What if my flat cannot have an outdoor unit?

Talk to your neighbours about a shared system, or look at efficient electric heating and insulation for now. Heat networks may reach parts of the city in future.
