Office Commercial Mortgages Cardiff

Underwriting a Cardiff office commercial mortgage

Cardiff carries one of the deepest regional office markets in the UK outside London, anchored by the Foster + Partners-led Central Square regen at Cardiff Central station and the Capital Quarter cluster across the railway in Tyndall Street. The commercial mortgage market splits into four practical bands. Central Square Grade A at the top, anchored by BBC Cymru Wales (Three Central Square), HMRC (6 Central Square / Ty William Morgan), Cardiff School of Journalism (Two Central Square), Blake Morgan and Julian Hodge Bank (One Central Square), institutional investors only, single-asset deals £15M+, rarely brokered. Capital Quarter and mid-prime CBD in the £1M to £5M bracket, mid-prime investment that we work most often, Capital Quarter buildings 1 to 4 hold Admiral Group plc HQ, Hugh James, Deloitte and Public Health Wales. Callaghan Square, Capitol Centre and Brunel House for secondary CBD investment stock. Cardiff Business Park Llanishen CF14 and Cardiff Gate Business Park CF23 at the suburban office park end.

Investment underwriting tests ICR at 140 to 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 to 1.5x, the accountancy practice converting from leasehold to a Capital Quarter floor purchase, the consultancy buying its Cathedral Road CF11 townhouse, the legal firm taking the freehold of its Callaghan Square building.

Worked example: a Capital Quarter 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 to 8.0% pa on a five-year fix. Worked example two: a Cardiff Innovation Campus-adjacent CF24 life-sciences floor purchase by a small biomed consultancy, £680K, EBITDA cover 1.4x. Owner-occupier route at 70% LTV places with Allica or Shawbrook at 7.25 to 7.5% pa.

Post-Covid Cardiff office stock has carried real value-add opportunity, particularly in the Callaghan Square, Capitol Centre and Brunel House secondary 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 CBD stock, and the Central Quay regen pipeline on the former Brains Brewery site (Vastint UK, 11.5 acres) continues to underpin demand on the western edge of the CBD.

Finance structures for Cardiff 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 Cardiff office

Strong on prime let stock with national covenants and unexpired lease term over five years. Mid-strength on secondary CBD 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 to 7.75% pa for 65% LTV with strong covenants. <strong>Shawbrook</strong>, Allica, HTB and Cambridge & Counties cover mid-market at 7.5 to 7.75% 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 to 9.25% pa. Welsh-HQ Principality Building Society and Monmouthshire Building Society available on owner-occupier deals where the trading business is Welsh-resident. Central Square Grade A above £15M routes through institutional debt outside the broker panel; below that band, our pool covers it.
