Mixed Use Property Landlord UK 2026 — SDLT Non-Residential Rates, Capital Allowances, VAT, and Planning

SDLT on mixed use property — non-residential rates and no 3% surcharge

• Non-residential SDLT rates apply to the whole price: where a property consists of both residential and non-residential parts, SDLT is charged at non-residential rates (0% up to £150,000, 2% from £150,001 to £250,000, 5% above) on the entire purchase price
• No 3% additional dwelling surcharge: the 3% additional dwelling surcharge (FA 2003 Schedule 4ZA) does not apply to mixed use properties — a property with a genuine commercial element is not solely a dwelling
• Genuine mixed use test: HMRC scrutinises SDLT returns to ensure the commercial element is real, functional, and reflected in the planning use — a derelict shop with a flat above that has been wholly residential for many years may not qualify
• Multiple dwellings relief abolished from 1 June 2024: MDR (Finance (No.2) Act 2023) cannot be combined with non-residential SDLT rates in any case — the mixed use non-residential rate is now the primary route to lower SDLT on multi-unit acquisitions

Capital allowances — commercial element qualifies, residential does not

• Plant and machinery (P&M): qualifying P&M within the commercial part — electrical systems, heating, lifts, shop fittings — qualifies for capital allowances; the annual investment allowance (AIA) allows 100% deduction of qualifying P&M up to £1m/year
• Structures and buildings allowance (SBA): 3% per year of the cost of construction or renovation of non-residential structures — applies to the commercial element only; not available for residential letting
• Integral features: electrical systems, cold water systems, heating systems, lifts within the commercial part qualify at the special rate pool (6% reducing balance per year)
• Apportionment on acquisition: the purchase price must be apportioned between residential and commercial elements; a professional surveyor's apportionment is essential — HMRC may challenge apportionments that artificially maximise the commercial element
• No capital allowances for residential: the residential element does not qualify; actual replacement furniture and fitting costs are deductible as revenue expenses under the replacement of domestic items relief

VAT — partial exemption and the option to tax

• Residential lettings — exempt from VAT: a landlord letting a flat above a shop cannot charge VAT on the residential rent and cannot recover input VAT on costs attributable to the residential element
• Commercial lettings — exempt unless option to tax exercised: the grant of an interest in commercial property is exempt from VAT unless the landlord has exercised an option to tax under VATA 1994 Schedule 10; once opted, the landlord charges 20% VAT on commercial rent and can recover input VAT on commercial costs
• Partial exemption: a mixed use landlord with opted commercial and exempt residential makes both taxable and exempt supplies; input VAT must be apportioned between taxable and exempt use — only the taxable commercial portion can be recovered
• TOGC — transfer of a going concern: transferring a mixed use property as a going concern (where the buyer is VAT registered and will continue the same economic activity) may allow VAT to be disapplied on the transaction

Planning, HMO licensing, ATED, and compliance for mixed use property

• Planning use class: the commercial element is typically within Use Class E (commercial, business, and service) covering retail, office, café, gym, health uses; converting a vacated commercial unit to residential Use Class C3 requires planning permission
• HMO licensing for upper floors: mandatory HMO licensing applies to the residential element independently of the commercial ground floor — a building with five or more persons from two or more households requires a mandatory HMO licence
• Fire safety — RRO 2005: the Regulatory Reform (Fire Safety) Order 2005 applies to all non-domestic parts; the responsible person must carry out and review a fire risk assessment; Building Safety Act 2022 imposes additional duties on higher-risk buildings
• EPC requirements: each separately let part requires its own EPC — a separate EPC for the residential flat(s) and a separate EPC for the commercial unit; MEES regulations apply to residential and commercial elements independently
• ATED: Annual Tax on Enveloped Dwellings applies to companies owning residential property worth more than £500,000; for mixed use buildings only the residential element is within ATED — the commercial element is excluded
