Guildford and Surrey deliver the UK's highest-irradiance warehouse solar economics — 1,020-1,060 kWh/kWp/yr — but SSEN G99 requires early action on large systems.
SSEN G99 — plan ahead
SSEN GU-postcode G99: study 45-65 working days, connection offer 6-10 months. Among the slower UK DNOs. Submit G99 immediately after structural survey. Below 1 MW: G98 self-notification available.
M25 J10/A3 corridor
Slyfield Industrial Estate (GU1 — regional distribution, 400 kW-1.5 MW PV); Guildford Business Park (GU2 — high-tech distribution); Merrow industrial (GU4 — parcel, pharma, specialist distribution). Self-consumption logistics: 74-81%. Payback: 4.5-5.5 years.
Pharma and defence supply chain
Surrey pharma cluster (GU, KT, RH): AstraZeneca distribution, Pfizer supply chain. Aldershot/Farnborough (GU11/GU14): BAES, QinetiQ supply logistics. Manufacturing self-consumption: 82-91%. IETF: 20-35% for qualifying operations.
MEES EPC B context
Institutional landlords (Prologis, Segro, GLP hold significant GU-postcode stock) face EPC B 2030 deadline. Solar 8-14 EPC point uplift is particularly valuable in high-value Surrey market. We provide MEES pathway assessment alongside solar feasibility.
