A genuine Scottish Highlands self-catering case

Highland Farm Cottages, near Dingwall in the Scottish Highlands, is a five-star self-catering holiday-let business set in converted stone barns and stables. It is a real, verifiable UK example of a holiday-let owner investing in renewables to cut energy cost and carbon and to strengthen their green-tourism credentials, and it is worth studying because independently reported figures exist for it, which is rare in this sector. The details below are drawn from the Resource Efficient Scotland case study published at resourceefficientscotland.com.

What was installed, and an important honesty note

The reported outcome comes from a mixed-renewables installation, not from solar PV alone. The business installed solar PV alongside a 150 kW biomass boiler across its converted stone buildings. That combination is the important context for every figure that follows: the biomass boiler carries the heating and hot-water load that would otherwise fall to oil or LPG, while the solar PV offsets electrical demand. We present this deliberately, because it would be misleading to attribute the whole saving to the panels. The published PV system size is not stated in the source, so we do not invent one.

The reason to include a mixed-renewables case on a solar site is that it shows, with real numbers, how a self-catering holiday-let business in a remote, off-gas-grid Highland setting made renewables pay across converted heritage buildings, and how the owner treats green energy as a booking advantage rather than a cost.

The reported outcome

According to the Resource Efficient Scotland case study, the project delivered:

• Capital investment of around £110,000 across the renewables installation.
• Total energy cost saving of over £19,000 a year from the combined renewables, biomass and solar together, not solar alone.
• Around 33.5 tonnes of CO2 saved a year.
• A payback of around 6.1 years on the combined investment.

The project was funded via the Scottish Government SME Loan Scheme, a route that has historically supported holiday-let renewables in Scotland. The business went on to win the 2016 Highland Business Award for ‘Best low carbon business’, and the owner reports that guests actively prefer a green-energy provider, which is consistent with the wider pattern we see across eco-conscious self-catering and glamping guests.

Why the figures make sense for this property type

The scale of saving fits the profile of a remote, off-gas-grid Highland self-catering business. Converted stone barns and stables are heat-hungry buildings, and a five-star operation running back-to-back guests through the season carries a heavy hot-water and heating load at every changeover. In that setting the biomass boiler displaces expensive off-grid fuel for heat, and the solar PV offsets the daytime electrical load that runs alongside it. The seasonal occupancy of a Highland let, busiest and sunniest through the same months, is exactly the profile that makes solar’s contribution to a mixed system worthwhile rather than idle.

The roughly 6.1-year payback reflects the combined economics of both technologies plus the SME Loan Scheme funding. On a solar-only basis a single self-catering property typically models to a longer indicative payback, which is why our own holiday cottage and lodge pages quote solar figures separately rather than borrowing this mixed-renewables number.

What a holiday-let owner can take from it

The transferable lesson is not a copyable system size, because this is a mixed installation on heritage buildings in a specific Highland setting. It is the shape of the case: a remote, off-gas-grid self-catering business with heavy seasonal heat and power demand can cut its energy cost substantially with renewables, fund it through an available loan scheme, and turn the result into a marketing and awards advantage that guests respond to. For a solar-and-battery equivalent on a single cottage, our clearly labelled illustrative coastal cottage model sets out solar-only figures without borrowing Highland Farm’s mixed-renewables saving.

If you run a self-catering business and want your own numbers modelled honestly, solar separated from any heat measure, and no figure borrowed from a different property, request a quote. We size from your own consumption and tell you what solar alone will and will not do.
