Funding in this region
South East projects benefit fully from the 100% AIA, asset finance and PPA structures. London commercial landlords often combine solar with MEES / EPC compliance work to lift building value.See UK grants & funding guide →

South East commercial solar FAQs
Are commercial solar panels worth it in the South East?
Yes — the South East has the UK's highest solar irradiance and dense commercial demand around the M25, M3, M4 and Felixstowe / Thames Gateway corridors. Combined with high commercial electricity tariffs, this typically delivers some of the strongest payback figures in the country.
Which South East areas do you cover?
London, Kent, Surrey, Sussex, Essex, Hertfordshire, Berkshire, Buckinghamshire, Hampshire and Oxfordshire — including industrial estates around Reading, Slough, Basingstoke, Dartford, Thurrock and Stansted.
How much energy will a South East rooftop system generate?
Typically 1,000–1,050 kWh per kWp installed per year — the highest UK band. A 250 kWp system can therefore produce 250,000+ kWh annually, offsetting a significant portion of a mid-sized commercial site's grid demand.
Do I need planning permission in the South East?
Most commercial rooftop solar falls under permitted development, but listed buildings, conservation areas and parts of London have stricter rules. We review every site individually before proposal.
