25 kW PV on a 9-Room Yorkshire Dales Boutique B&B

Modelled worked example — the figures below are built from sourced 2026 UK cost and generation benchmarks for a property of this profile, not a claimed client project.

The hotel

A 9-room family-owned 4-star Gold boutique B&B in the Yorkshire Dales National Park, with a 40-cover destination restaurant, in-house laundry, and substantial year-round occupancy (88% annual average). Grade II listed Georgian conversion with later Victorian extension and unlisted stable block. Annual electricity spend £33,000.

The brief

Reduce the property’s largest controllable cost line, deploy a venue sustainability narrative for the wedding micro-segment (12-15 weddings/year), and navigate the Yorkshire Dales National Park Authority planning notification.

The modelled system

25 kW rooftop array distributed across the unlisted stable-block roof (18 kW) and the unlisted Victorian extension (7 kW). Grade II main house untouched. Yorkshire Dales NPA notified at planning stage, conservation officer pre-application meeting secured at Richmondshire DC. MCS domestic certification (single combined meter). Capital purchase with AIA shield through the trading limited company.
