UK warehouse solar by sector
The economics of warehouse solar vary enormously by warehouse type. A 24/7 cold storage facility achieves 88-95% self-consumption and a 3.8-4.8 year payback; a single-shift cross-dock depot achieves 65-75% self-consumption and a 6-7 year payback. The customer audit requirements differ too — a retailer distribution centre faces Tesco/M&S Scope 3 mandates, while an automotive parts warehouse faces JLR/Stellantis Tier-1 requirements.
We have organised our 12 specialist warehouse sectors into four groups below. Each sector page covers system sizing, self-consumption, payback economics, customer audit programmes, and case studies specific to that warehouse type.

Why warehouse sector matters for solar economics
The single most important variable in warehouse solar economics is the self-consumption ratio — the share of generated electricity used on site rather than exported. This is determined almost entirely by the warehouse operating pattern, which is why sector matters so much. A cold storage facility running 24/7 refrigeration consumes electricity around the clock, absorbing 88-95% of its solar generation directly. A single-shift cross-dock depot operating 8am-5pm absorbs only 65-75%, exporting the rest at lower SEG rates. The same 1 MW system delivers a markedly different return depending on which warehouse it sits on.
Sector and customer Scope 3 audit requirements
Beyond economics, the customer audit landscape differs by sector. Retail distribution centres serving Tesco, M&S, Sainsbury's and Amazon face those retailers' Scope 3 supplier mandates. Automotive parts warehouses serving JLR, Stellantis and Toyota face OEM Tier-1 supplier requirements. Cold chain operators face BRCGS Storage and Distribution audit integration alongside retailer mandates. Pharmaceutical warehouses face GMP and Scope 3 requirements. Each of our sector pages covers the specific customer audit programmes relevant to that warehouse type, and our monitoring platform generates audit reports formatted for each.
