Northampton is geographically at the heart of the UK Golden Triangle — equidistant from London, Birmingham, and the Midlands, with excellent M1/A14/A45 road access and significant rail freight proximity. The Northampton fulfilment market includes: Daventry International Rail Freight Terminal (DIRFT — the UK's most successful rail-linked fulfilment park: Amazon, Tesco, Wincanton, DHL, CEVA national DCs all based here); Brackmills Industrial Estate; Moulton Park; and Grange Park. Irradiance (920-960 kWh/kWp/yr) is excellent for the Midlands.
Local context — Northampton
Northampton fulfilment solar is driven by DIRFT building stock quality (modern, large-format, excellent PV roofs), Western Power Distribution G99 (5-7 months), and concentrated Amazon/Tesco/major retailer Scope 3 requirements. Self-consumption at automated fulfilment (sortation, AMRs, robotics): 84-91%. DIRFT buildings average 500,000+ sqft — delivering 1-4 MW of rooftop PV per building. The Golden Triangle tax base (no specific Freeport, but standard 100% AIA) combined with high irradiance makes Northampton the highest-returning location in the UK for mainstream fulfilment solar.
