The three meanings of 'limited company residential mortgage'
- SPV BTL mortgage — special purpose vehicle company holds residential property to let out. This is what 95% of landlords mean. Mainstream specialist product, sharp pricing.
- Commercial mortgage on residential property — a trading company (not just an SPV) buys residential property as part of its business activity. Niche, expensive, complex.
- Personal residential via a company — director wants to live in company-owned house. Effectively impossible to do tax-efficiently in the UK.
SPV BTL: the mainstream limited company route
An SPV is a freshly-incorporated UK limited company set up solely to hold property. Standard SIC codes: 68209 (other letting and operating of own or leased real estate) or 68100 (buying and selling of own real estate). Lenders require:
- SPV with no trading activity other than property.
- Personal guarantee from all directors with 20%+ shareholding.
- Standard BTL stress test: 125% ICR (corporation tax adjusted) at 5.5%–7% stressed rate.
- Director/shareholder credit checks.
2026 SPV BTL rate bands
- 60% LTV 5-year fix: 5.20%–5.60%
- 75% LTV 5-year fix: 5.50%–6.30%
- 80% LTV 5-year fix: 6.30%–7.00%
- HMO SPV: add 0.40%–0.80%
- Holiday let SPV: add 0.50%–1.00%
Arrangement fees typically 1.5%–3% of loan — higher than personal name (1%–2%).
Commercial mortgages on residential property
If your trading company (e.g. a care home operator, hotel group, hostel) needs to hold residential property as part of trade, commercial lenders apply different rules:
- Underwritten on company accounts, not rental ICR.
- 2–3 years' filed accounts required.
- LTV typically 65%–70%.
- Rate 6.50%–8.00% on 3–5 year terms.
- Personal guarantees usually required.
Lenders: Allica, Cambridge & Counties, Shawbrook, OakNorth, Together.
Why personal residential via a company fails
If a director lives in a property owned by their limited company, HMRC treats this as a benefit-in-kind (BIK). The director pays income tax on:
- The annual rateable value of the property (basic charge), plus
- Additional charge: (cost of property above £75k) × HMRC official rate (currently ~2.25%).
Worked example: £400,000 house owned by your company. Additional BIK = (£400k − £75k) × 2.25% = £7,312/year on top of rateable value. At 40% tax that's £2,925 extra income tax annually — and you still need to fund the mortgage from after-tax company money. Almost always cheaper to own personally.
SPV BTL vs personal name decision
- Use SPV when: you're a higher-rate taxpayer; you're building a portfolio of 3+ properties; you want to retain profits for further investment; you want full mortgage interest deductibility.
- Use personal name when: you're a basic-rate taxpayer; you have 1–2 properties; you need rental income to live on; you want simpler tax returns.
Pros
- Full mortgage interest deductibility against rental profit.
- Corporation tax (25%) lower than higher-rate income tax (40%/45%).
- Profits retained in the company for portfolio growth.
- Sharper after-tax returns for higher-rate landlords.
- Wide specialist SPV lender pool in 2026.
Cons
- Rates ~0.20%–0.40% above personal-name BTL.
- Arrangement fees higher (1.5%–3%).
- Annual accounts and corporation tax filing cost £500–£1,500.
- Personal guarantees required from directors.
- Extracting profits triggers dividend or salary tax.
