Office Commercial Mortgages Devon

Underwriting a Devon office commercial mortgage

Devon's office market centres on Exeter, the county town and the deepest professional-services cluster in the South West outside Bristol, with Plymouth providing a second pole anchored by marine, defence and the University of Plymouth. The commercial mortgage market splits into four practical bands. Exeter Science Park and Plymouth Science Park Grade A at the top, institutional and corporate-occupied stock, larger single-asset deals rarely brokered. Marsh Barton, Sowton and Exeter Business Park in the £1M–£5M bracket, the secondary stock we work most often. Exeter Quay and central Exeter for professional and period stock. Converted heritage and creative office at £400K–£2M across Exeter Quay and the central conservation areas.

Investment underwriting tests ICR at 140–155% on let office stock. Tenant covenant carries even more weight than on retail, a five-year unbroken lease to a national professional services firm prices materially better than the same building let on three two-year leases to local independents. Multi-let assets with rolling renewals price at the wider end. Owner-occupier office routes through the EBITDA-cover product at 1.3–1.5x, the accountancy practice converting from leasehold to a Marsh Barton floor purchase, the consultancy buying its Exeter Quay townhouse, the legal firm taking the freehold of its Southernhay building.

Worked example: a Marsh Barton 6,500 sq ft office investment, £1.85M valuation, let on a 7-year FRI to a regional law firm at £125K passing rent. ICR at 145% sizes a £1.2M loan at 65% LTV; Lloyds, NatWest and Santander all price this profile at 7.5–8.0% pa on a five-year fix. Worked example two: an Exeter Quay creative-office freehold purchase by a small architectural practice, £680K, EBITDA cover 1.4x. Owner-occupier route at 70% LTV places with Allica or Shawbrook at 7.5–7.25% pa.

Post-Covid Devon office stock has carried real value-add opportunity, particularly in the central Exeter and Marsh Barton bands. Vacant or part-let assets purchased through bridge-to-let, refurbished to current EPC and amenity standards, then re-let and termed out onto investment mortgage. Shawbrook, LendInvest and Hampshire Trust Bank have been the most active on this strategy. The EPC-B requirement effective from 2030 has accelerated refurbishment activity on secondary office stock.

Finance structures for Devon office

Investment routes via commercial investment mortgage on ICR; owner-occupier via the EBITDA-cover route; vacant or value-add via bridge-to-let with an agreed term-out. Larger multi-asset office portfolios consolidate via portfolio refinance.

Lender appetite for Devon office

Strong on prime let stock with national covenants and unexpired lease term over five years. Mid-strength on secondary stock with mid-covenant tenants on shorter leases. Tighter, but still fundable, on vacant or part-let secondary office routed through bridge-to-let with a credible refurbishment story. <strong>NatWest</strong>, <strong>Lloyds</strong>, <strong>Barclays</strong> and <strong>Santander</strong> compete on prime investment at 7.0–7.75% pa for 65% LTV with strong covenants. <strong>Shawbrook</strong>, Allica, HTB and Cambridge & Counties cover mid-market at 7.75–7.5% pa. <strong>InterBay Commercial</strong>, <strong>LendInvest</strong> and <strong>Cynergy Bank</strong> handle secondary, short-lease and refurb-to-let stories at 8.25–9.25% pa. Exeter Science Park and Plymouth Science Park Grade A at the larger end routes through institutional debt outside the broker panel; below that band, our pool covers it.
