30 Second Briefing
Railpen has secured planning consent for phase 2 of its High Wycombe X industrial and logistics park at Cressex Business Park, delivering about 145,000 sq ft across five units on a 360,000 sq ft site and targeting completion in Q2 2027. Booker has pre-let 47,300 sq ft and Activeon 25,600 sq ft, both on 20-year leases, signalling strong long-term demand for the scheme. The development is targeting BREEAM Excellent, EPC A+ and net zero carbon in construction, with a third 120,000 sq ft phase already submitted for planning.
Technical Brief
- Phase 2 adds five industrial/logistics units within the existing 360,000 sq ft Cressex Business Park footprint.
- Railpen is the developer, acting on behalf of the railway pensions scheme investment portfolio.
- Phase 1 of High Wycombe X completed in the previous year, providing proof-of-concept for the park.
- Booker’s 47,300 sq ft pre-let supports food-grade servicing requirements and associated yard/servicing infrastructure.
- Activeon’s 25,600 sq ft unit will require clear internal heights and vibration‑controlled slabs for trampoline operations.
- Both occupiers’ 20‑year lease terms support long‑horizon funding of envelope, M&E and low‑carbon fabric upgrades.
- Net zero carbon in construction will drive low‑embodied‑carbon materials selection and on‑site construction logistics planning.
- A further 120,000 sq ft third phase is already in planning, indicating a multi‑phase infrastructure delivery strategy.
Our Take
Railpen’s High Wycombe X scheme adds a logistics/industrial asset in the South East to a portfolio that, in our database, also includes urban office-led redevelopments like 12 Smithfield in London and the Mill Yard campus in Cambridge, signalling a deliberate spread across income types and geographies within the UK.
The 20‑year leases to occupiers at High Wycombe X mirror the long‑income profile Railpen has been targeting in other recent projects, which is consistent with pension‑fund strategies seeking inflation‑resilient, low‑churn cashflows from core infrastructure‑style assets.
