These named London industrial estates and business parks typically host the kind of large-roofed commercial buildings well-suited to on-site PPA — factories, warehouses, logistics centres, distribution hubs.
Sites within these estates typically qualify for 250kWp+ on-site PPAs. For mid-size buildings (100-250kWp) we recommend the standard on-site route; for mega-sheds (1MWp+) consider a behind-the-meter or corporate-PPA structure.
London Plan supports rooftop solar across commercial and residential. London Energy Efficiency Fund provides finance to public buildings. PV expected on all major new commercial development under London Plan Policy SI 2.
For commercial off-takers, the local net-zero target provides supporting context for solar PPAs in two ways: (a) planning consent for ground-mount and large rooftop solar is typically supported, and (b) tenant ESG mandates within the local supply chain are stronger than in less-ambitious regions.

Indicative 2026 tariffs for London sites range 10-18 p/kWh year 1 depending on system size, off-taker covenant, term length and DNO context. Larger systems (500kWp+) with strong covenants on 25-year contracts can achieve the lower end of the range. The Greater London Authority has a 2030 net-zero target which supports business demand for PPAs.
In London the most active PPA cohorts are typically manufacturing, logistics, hotels, schools and NHS Trusts. Named industrial estates including Park Royal, Brent Cross, Greenwich Peninsula are particularly suited to roof-mounted PPAs.
DNO context — specifically G99 connection availability and export capacity — drives the build cost (and hence tariff) of any PPA-funded system. For London, ground capacity is generally workable but the G99 application alone takes 6-12 weeks. Larger systems (250kWp+) often require additional studies.
From first call to commissioning typically 6-12 months. Indicative tariff in 2-4 weeks; site survey + heads-of-terms in 4-8 weeks; full contract in 8-12 weeks; build in 6-16 weeks. Site complexity, planning consent and DNO connection drive variations.
Sites within ~30 miles of London typically draw on the same provider network. For multi-site portfolios across neighbouring towns (Croydon, Bromley, Dartford, etc.), a sleeved-PPA or corporate-PPA structure aggregates the kWh more efficiently than separate on-site contracts.
A 60-second form gives us enough to match you to PPA providers active in London and return a 11 p/kWh-band indicative tariff.
