Commercial Mortgages Cambridge Science Park

The Cambridge Science Park commercial property market

Cambridge Science Park is the flagship office and lab investment cluster in Cambridgeshire. The CSP estate carries 152 acres, around 2 million sq ft of office and lab floorspace, and is owned by Trinity College, which acts as long-term ground landlord on the majority of the estate. Tenant mix is dominated by life-sciences (Abcam, multiple lab occupiers), software and engineering (Domino Printing, Toshiba Research Europe, ARM's historical Cambridge presence) and a long tail of growth-stage Silicon Fen companies. The adjacent St John's Innovation Park, owned by St John's College, plays a similar role on the eastern flank of the same Milton Road corridor.

Pricing on CSP investment runs tight by UK standards. Prime lab rents 2026 are 55 to 65 pounds per sq ft for new and refurbished space, with office headline rents at 35 to 45 pounds. Investment yields on prime CSP lab and office stabilised stock sit at 5.5 to 6.5%, materially keener than the wider regional commercial market reflecting the depth of life-sciences occupier demand and the structural shortage of new floorspace coming forward. Commercial mortgage rates are not the same as investment yields, mortgage rates for the underlying commercial investment on CSP-adjacent stock sit in the 6.0 to 8.5% pa band depending on tenant covenant and lease length.

HM Land Registry residential transactions across CB4 confirm a structurally premium catchment supporting CSP tenant covenant assumptions. Recent files include CB4 1LL Warren Road at £665,000 and CB4 1RN Green End Road at £472,000. We use that as directional temperature on tenant covenant strength for retail and F&B serving the CSP catchment, not as a commercial comparable. Stamp duty land tax applies at the commercial rates on every freehold commercial purchase; the long-leasehold structure of much of the CSP estate changes the SDLT calculation, your conveyancer will price it.
