What types of homes in Aberdeen suit solar?
Aberdeen\'s city housing is distinctive: granite tenements and villas with solid stone walls and slate roofs. The granite itself does not prevent solar installation — what matters is the condition and orientation of the roof. Many Aberdeen roofs use original slate that may need repairs or replacement before panels are fitted. Suburban developments around the city edge have standard tile roofs that are straightforward.
In rural Aberdeenshire, farms and crofts often have large barn roofs that are ideal for bigger solar arrays, and open land can suit ground-mounted systems if the roof is not suitable. These larger systems usually need a G99 application to SSEN rather than a simple G98 notification.
How does the oil-to-heat-pump transition work in Aberdeen?
Many Aberdeen and Aberdeenshire properties are off the gas grid and heated by oil, which makes a heat pump a compelling alternative. The transition starts with a room-by-room heat loss survey that checks whether your home can hold the lower flow temperatures a heat pump needs, given solid granite walls that behave differently from modern cavity construction.
The survey also shows which radiators need upgrading and whether you need a hot water cylinder, since most oil systems use one already. Once the heat pump is commissioned, the oil tank can usually be removed, freeing up outdoor space. Our heat pumps guide explains the technology in more detail.
Can heat pumps work with granite solid walls?
Yes, but solid granite walls have different insulation characteristics than cavity walls, so the heat loss survey is especially important. Some Aberdeen granite properties benefit from internal wall insulation before a heat pump is fitted, which improves efficiency and can reduce the size of heat pump needed. This is assessed honestly at survey stage — not every granite home needs insulation upgrades.
Radiator sizing is the other key factor. Heat pumps run at lower flow temperatures than oil boilers, so some rooms may need larger radiators. Underfloor heating suits heat pumps very well where it can be installed, particularly in new extensions or during renovations.
What about batteries and solar on Aberdeenshire farms?
Rural Aberdeenshire farms can benefit from larger solar arrays on barn roofs, paired with battery storage to shift daytime generation into the evening when farm buildings and farmhouse use most power. Ground-mounted arrays are an option where roof space is limited or poorly oriented. These systems usually exceed the 3.68kW G98 threshold and need a G99 application to SSEN.
Our business and farms page covers larger-scale renewable installations for agricultural and commercial properties, and our battery storage guide explains how storage works with solar and time-of-use tariffs.
What drives the cost of an Aberdeen installation?
Granite vs cavity wall
Solid granite walls affect heat pump design and may call for insulation upgrades before installation.
Oil tank removal
Removing an old oil tank and flue adds to the work when switching to a heat pump.
Slate roof condition
Original Aberdeen slate may need repairs or replacement before panels are fitted.
Rural access
Farms and remote Aberdeenshire properties can involve longer travel and logistics.
System size
Farm arrays and larger heat pumps cost more but serve bigger heat or electricity demand.
SSEN DNO
G99 applications to SSEN typically take six to eight weeks, longer than the Central Belt.
How long does an Aberdeen installation take?
For a straightforward Aberdeen house, expect roughly six to eight weeks from survey to installation, with the physical fit taking one to two days. The slightly longer timeline reflects SSEN G99 processing for systems above 3.68kW. Rural Aberdeenshire farms with larger arrays may take longer due to G99 approval and logistics. Oil-to-heat-pump transitions add time for tank removal and any insulation work.

Common questions
Can I switch from oil heating to a heat pump in Aberdeen?
Yes. Many Aberdeen and Aberdeenshire homes are off the gas grid and heated by oil, which makes a heat pump a strong alternative. A heat loss survey checks your property's insulation and radiator sizing. The oil tank can usually be removed once the switch is complete, freeing up garden space. We install through MCS-certified partners.
Which network operator covers Aberdeen?
Aberdeen and much of the north-east is served by SSE Networks (SSEN). Systems up to 3.68kW (16 amps) are notified after installation under G98. Larger systems need a G99 application submitted before work begins, which SSEN typically processes in around six to eight weeks, sometimes longer in rural parts of Aberdeenshire.
Are solar panels suitable for granite Aberdeen buildings?
Solar panels can be fitted to granite buildings, but solid granite walls mean the roof structure and slate condition matter more than the wall material itself. The key considerations are roof orientation, shading and whether the slate is sound. Granite's solid wall construction is more relevant to heat pump design than to solar installation.
Do you install renewables on Aberdeenshire farms?
Yes. We cover rural Aberdeenshire including farms and crofts. Farm installations may involve larger solar arrays on barn roofs, ground-mounted systems, and heat pumps for farmhouse heating. Rural locations can involve longer G99 timelines and access considerations. We also cover business and farm properties — see our business and farms page.
What does a heat pump cost in Aberdeen?
Heat pump costs depend on your property, heat demand, radiator upgrades and whether a hot water cylinder is needed. Off-gas Aberdeen homes heated by oil often find a heat pump competitive. Interest-free credit up to £30,000, subject to status. A no-obligation survey gives you an honest, fixed quote for your specific property.
