Defining mixed-use property: when does semi-commercial pricing apply?
Semi-commercial finance is a single facility funding mixed-use property, typically a commercial unit on the ground floor with one or more self-contained residential flats above. Where the residential element is at least 40% of total floorspace, semi-commercial pricing applies (instead of pure commercial investment pricing). Where residential is below 40%, lenders treat it as commercial investment and price accordingly.
The lending test combines the commercial rent and the residential AST income on a blended basis, with a typical cover requirement around 145%. Lenders take comfort from the residential security: a flat above is easier to re-let than a vacant retail unit if the commercial side falls vacant, so semi-commercial routinely prices 50 to 100bps inside pure commercial investment. Loan-to-value to 75% is achievable on standard Bournemouth archetypes via specialist desks; BCP valuers can trend conservative on the commercial slice on Boscombe Christchurch Road and outer Charminster Road parades where retail rents have been volatile, which sometimes caps the achievable LTV below the headline.
Specialist lenders dominate this market. InterBay Commercial (OSB Group) and Shawbrook are the two most active named desks; LendInvest and Cynergy Bank also run active programmes for Bournemouth semi-commercial deals between £200K and £2.5M. HTB, Allica Bank, Aldermore, Foundation Home Loans, Together and Cambridge & Counties engage actively across the south coast. Limited company SPV structures are standard; individual investor and LLP variations are equally accommodated.
Regulation matters here. Most semi-commercial lending is unregulated commercial: the borrower is a limited company or investor, the residential flats are let on ASTs to third parties. The exception: where the borrower (or an immediate family member) will personally occupy one of the flats, the deal can fall into FCA-regulated mortgage rules and routes to a regulated commercial lender. Stamp duty land tax follows non-residential rates on the whole property where commercial use is genuinely incidental, which is materially cheaper than residential SDLT and is part of why investors favour the structure. Indicative case seed: a Charminster Road parade unit with three flats above at £580K, blended rent £40K pa, structured at 70% LTV (£406K facility) with InterBay Commercial or Shawbrook at around 7.0% pa.
Underwriting steps for a Bournemouth shop-and-flats deal
1. Tenancy and split review
We check residential and commercial floorspace split, leases on the commercial side, ASTs on the residential side, tenant covenant on each.
2. Indicative terms in 48 hours
Three to four specialist semi-commercial lenders quoted: interest rate, loan-to-value, term, fees.
3. Credit pack
Lease pack, AST pack, property file, borrower SPV (or individual) pack. InterBay Commercial and Shawbrook want clean tenancy evidence.
4. RICS Red Book valuation
Separates commercial value, residential value and total. Estimated rental value on the commercial unit important to the cover test. Old Christchurch Road conservation-area parades add time for heritage considerations.
5. Credit approval
Specialist desks typically approve in 1 to 2 weeks post-valuation.
6. Legal completion and SDLT
Standard mixed-use conveyancing. Stamp duty at non-residential rates applies on the whole. 3 to 5 weeks typical.

Active Bournemouth semi-commercial parades and lender behaviour
Semi-commercial is a deep, active product across Bournemouth, sharpened further by the BCP catchment's sustained Class E to mixed-use reshuffles where upper floors over retail have flipped from B-class office to C3 residential under permitted development, putting fresh semi-commercial stock on the market. The classic parades, Charminster Road in BH8, Westbourne Arcade and Poole Road in BH4, Old Christchurch Road central in BH1, and Southbourne Grove in BH6, run on shop-with-flat-above formats backed by exceptionally durable residential demand from the c. 22,500 combined Bournemouth University and Arts University Bournemouth student footprint, the JPMorgan Chase Littledown professional employment shed, the University Hospitals Dorset NHS Trust workforce, and the wider c. 400,000 BCP population. Lot sizes are typically £280K to £900K for a single parade unit, often £1.2M+ for a four-unit run with multiple flats above. Gross blended yields run wider than the regional UK average given the BCP catchment's renter-heavy stock: typically 7.0 to 8.5% blended on Charminster Road and Westbourne, slightly wider on Boscombe Christchurch Road and outer Old Christchurch Road parades. Recent change-of-use volume (Lansdowne Class E to C3 prior approval cases, Boscombe Spa Village mixed-use regeneration, Old Christchurch Road sub-division reshuffles) is typical Bournemouth semi-commercial profile. Lender appetite is strong: InterBay Commercial, Shawbrook, LendInvest and Cynergy Bank all actively quote on Bournemouth semi-commercial deals; HTB, Allica Bank, Aldermore, Foundation Home Loans, Together and Cambridge & Counties engage actively across the south coast.
