Semi-Commercial Bridging Loans: Financing a Flat Above a Shop (UK)

Short answer: a semi-commercial bridging loan is short-term finance secured on a property that is partly commercial and partly residential, such as a shop with one or two flats above. Lenders look at both parts: the commercial unit, its lease and tenant, and the residential element. The deal stands or falls on a realistic valuation, the right tax treatment and a clear plan to repay the bridge, usually by sale or by refinancing onto a longer-term commercial mortgage.

Mixed-use buildings are common on UK high streets, and they often come up at auction or in a hurry, when a long mortgage application would be too slow. Bridging is one way to secure them quickly, but not every lender will lend on them, and those that do set their own limits. Some specialist business lenders state their position openly; ealholdings.co.uk, for example, lists residential, commercial and semi-commercial property among the types it considers for property-secured finance. Whoever you approach, the questions below will help you understand how the property will be judged.

This guide is general information for company buyers and property professionals, not advice.

What counts as semi-commercial property?

For lending, semi-commercial usually means a single title or building that combines business and residential use. Typical examples include:

a shop, café or salon with a flat or maisonette above;
an office building with residential units on upper floors;
a pub with living accommodation;
a parade of shops with several flats above.

HMRC uses a similar idea for Stamp Duty Land Tax. GOV.UK describes a "mixed" property as one that has both residential and non-residential elements, giving the example of a flat attached to a shop, doctor's surgery or office.

Why does the split between shop and flat matter to a lender?

Regulation is one reason. Under the FCA's guidance in PERG 4.4, a regulated mortgage contract involves credit to an individual or trustees, secured on land where at least 40% is used, or intended to be used, as or in connection with a dwelling. So an individual borrowing against a building that is mostly residential may fall into the regulated mortgage regime. Where a company that is not acting as a trustee borrows for its business and secures the loan on its own property, the FCA says the contract is not a regulated mortgage contract.

Valuation is the other. The residential part may be easier to sell or let, while the commercial part's value often depends on the lease: how long is left, the rent, the tenant's strength and whether the unit is empty. A long vacant shop can pull down the overall figure, and some lenders reduce the loan-to-value they will offer on properties with a large commercial element.

What does the lender usually look at?

Leases and tenants: copies of commercial and residential tenancies, rent levels and any arrears.
Title: whether the flats and shop are on one title or several, and any existing long leases of the flats.
Condition and access: separate entrances, fire separation and services, which can affect both value and lettability.
Planning use: whether the current uses are lawful, and whether any planned change of use has permission.
Energy ratings: each part may need its own Energy Performance Certificate.
Exit: sale, refinance or a mix, with evidence that it is achievable in the term.

How is Stamp Duty worked out on mixed-use property?

In England and Northern Ireland, mixed-use purchases are charged at the non-residential rates. GOV.UK sets out the bands for freehold and mixed purchases as follows.

Portion of the price	SDLT rate
Up to £150,000	Zero
£150,001 to £250,000	2%
Above £250,000	5%

For a new non-residential or mixed lease, SDLT on the rent is based on its net present value: nothing is due if the NPV is under £150,000, 1% applies between £150,001 and £5 million, and 2% on any amount above that. Whether a property is genuinely mixed-use depends on the facts, so ask your conveyancer to confirm the treatment before exchange rather than assuming. Scotland and Wales have their own land taxes.

What are the energy rules for letting each part?

Minimum energy efficiency standards apply to both sides of the building in England and Wales:

Commercial unit: since 1 April 2023, privately rented non-domestic property needs at least an EPC E rating unless a valid exemption is registered.
Flats: domestic private rented property generally cannot be let below EPC E either, unless an exemption applies, with a cost cap of £3,500 including VAT on required improvements.

If you plan to refinance onto a term loan or mortgage, a lettable building with compliant ratings is far easier to fund, so build any energy works into the bridging period.

How do you plan the exit?

Bridging is designed to be repaid within months, so the exit is the most important part of the case. Common routes include:

Refinance onto a commercial or semi-commercial mortgage once the property is let, improved or has trading history.
Sale of the whole building after works or once the commercial unit is let.
Selling or refinancing parts separately, for example granting long leases of the flats, which may need separate titles and legal work.

Model what happens if the shop takes longer to let than you hope. A vacant commercial unit can make both refinancing and sale harder, and bridging interest keeps adding up in the meantime.

Questions to ask a lender

Do you lend on semi-commercial property, and does the commercial share affect the maximum LTV?
Will the valuer value the building as one, or the parts separately?
Will you lend on a vacant commercial unit?
Is interest rolled up, retained or serviced, and what is the net amount released?
What exit evidence do you need at application?
Do you take first or second charges, and will you need personal guarantees?
What are the extension and default terms if the exit is delayed?

An example of a lender's published criteria

EAL Holdings, a business lender registered in England and Wales with its registered office in Harrow, Middlesex, states on its website that its property-secured finance covers residential, commercial and semi-commercial property, from £100k to £500k over 1 to 24 months, with up to 75% LTV and first and second charges considered. It lists auction purchases, chain breaks and refurbishment as typical uses, offers rolled-up or serviced interest, and says it currently lends to UK-registered companies only and does not lend to consumers. Published figures are maximums subject to the lender's assessment, not offers.

Frequently asked questions

Is a semi-commercial bridging loan more expensive than a residential one?

Pricing varies by lender and deal. Lenders weigh the commercial element, lease strength and condition, so get written terms and compare the total cost.

Can I get a semi-commercial bridging loan on an empty shop?

Some lenders will consider it, but a vacant unit can lower the valuation and the loan, and the exit needs to show how the unit will be let or sold.

Do I pay business rates on the shop and council tax on the flat?

Usually the commercial part is assessed for business rates and each self-contained flat for council tax, but check your own situation with the local council and the Valuation Office Agency.

Is semi-commercial lending to my company regulated?

Generally not, where a company borrows for its business on its own property, according to the FCA's PERG guidance. That means fewer protections, so read the loan terms carefully.
