Assess motorway connectivity (M55→M6), typical transit times to your top ZIP/postcode clusters, carrier densities (parcel, pallet networks, express), and proximity to seaports or rail terminals. Request lane‑specific lead times and sample carrier rates to verify modelled transit time and cost assumptions.

Prioritize a modern WMS with API connectivity, real‑time inventory visibility, scalable pick/pack throughput, returns management, and temperature‑controlled storage if required. Verify peak capacity plans, onboarding timelines, and SLA measurement/reporting capabilities.

Blackpool often offers lower occupancy and labour rates, reducing fixed warehousing cost per pallet. However, evaluate transport costs to customer clusters—southern hubs can cut last‑mile transit to London. Model landed cost per order (rent + handling + outbound carriage) for your actual SKU mix and delivery patterns.

Negotiate order cycle time, OTIF percentage, inventory accuracy, pick/pack error rate, dock‑to‑despatch time, and agreed capacity uplift terms. Include chargeback clauses for missed SLAs and clear definitions for exceptions and seasonal throughput guarantees.
