Typical landlords in West End
Major landlord ownership in West End: Crown Estate, Grosvenor Estate, Howard de Walden Estate, Cadogan, Shaftesbury Capital. We work with landlord asset-management teams on MEES 2030-positioned solar capex programmes — service-charge structure compliance with the RICS Code 2018, tenant communication strategy, multi-building portfolio procurement.
Major occupiers in West End
Notable occupiers in West End include Apple, Meta, Centrica, Sony Music, Universal Music, hedge funds, family offices. For occupier-led installs we manage green-lease addendum drafting with the landlord, structural and electrical assessment to BS EN 1991 / BS 7671, and Scope 2 emissions documentation for ESG reporting (SECR, TCFD, CDP, SBTi).
System sizing for West End offices
100-400 kWp on rooftop (heritage-constrained); BIPV on later additions. Capex typically £700-£1,000/kWp on rooftop installs, higher for BIPV alternatives where required by heritage context. Cash payback 4-7 years; PPA route delivers cash-flow positive month one.
Planning route — West End
Westminster, Camden, K&C LPAs. Conservation Areas everywhere (Mayfair, Marylebone, Soho). High proportion listed. Westminster has Article 4 directions across much of W1. For most West End commercial offices, solar PV up to 50 kWp on non-listed buildings is Permitted Development under Class A Part 14 GPDO 2015. Above 50 kWp requires Prior Approval (56-day determination). Listed buildings need Listed Building Consent regardless of size — our 78% approval rate across heritage settings holds for West End too.
The West End opportunity
Crown Estate net-zero commitments; Mayfair/St James's landlord net-zero strategies; Cadogan Estate sustainability programme. Combined with MEES 2030 enforcement landing 1 April 2030, the capex window for landlord and occupier action is the 2026-2028 cycle.
