Solar PPA for care homes in London

Round-the-clock demand makes London care homes a strong PPA fit

Residential care never powers down. Overnight staffing, industrial laundry cycles, electric hot water and space heating give a London care home the kind of flat, 24/7 base load that a solar power purchase agreement converts most efficiently — every daylight unit generated on the roof is consumed on site rather than exported. Against the capital's steep commercial rates (London's average commercial energy spend of around £95,000 sits well above the national norm), a rooftop array of the 30–150kWp typical for the sector can shave a meaningful slice off the bill with no capital outlay. Under a PPA the operator simply pays for solar output at a fixed 14–18p/kWh, comfortably below imported grid power.

Where the capital's care operators sit

London's care homes cluster in the residential outer boroughs rather than on trading estates, though larger group operators run purpose-built facilities close to commercial hubs such as Park Royal, Stratford and the Greenwich Peninsula. Demand also spills into the neighbouring belt — Croydon, Bromley and out towards Watford and Slough — where land is cheaper and newer, larger homes are being developed. All of these sites connect through UK Power Networks, the DNO for London and the wider South East, whose commercial connection process shapes how quickly a PPA array can be energised.

Policy tailwind and the numbers

The Greater London Authority is targeting net zero by 2030, and the London Plan (Policy SI 2) already expects rooftop solar on major new commercial development, with the London Energy Efficiency Fund backing public-building retrofit — a supportive planning backdrop for a care operator considering panels.
