    Limited Company BTL Mortgage Rates: 2026 SPV Pricing, Lenders and Real Numbers

    Limited company buy-to-let — typically structured through a Special Purpose Vehicle (SPV) — now accounts for the majority of new BTL purchases in the UK. The driver is Section 24 of the Finance Act 2015, which restricts mortgage interest tax relief for personal-name landlords to a 20% credit. Inside a limited company, mortgage interest is fully deductible. This guide walks through every aspect of 2026 limited company / ltd company BTL mortgage rates: who lends, where they price, the SPV vs trading company split, ICR stress tests, personal guarantees, director income requirements and the after-tax maths that drives the structure decision.

    2026 rate landscape

    Indicative pricing across the UK SPV BTL market in 2026 (vanilla 2-bed flat, clean credit, experienced landlord):

    • 75% LTV 5-year fix: 5.40%–5.95%
    • 75% LTV 2-year fix: 5.60%–6.20%
    • 80% LTV 5-year fix: 5.85%–6.40%
    • 85% LTV 5-year fix: 6.40%–7.00% (specialist only)
    • Tracker (75% LTV): BoE + 2.10%–2.60%

    Arrangement fees on SPV BTL products are typically 1.5%–3% of the loan, occasionally 5% on the sharpest headline rates. Use total-cost calculations over the fixed-rate term to compare like-for-like.

    SPV vs personal name: the tax driver

    Worked example: a higher-rate taxpayer with a £180,000 BTL mortgage at 5.5% (£9,900 annual interest) and £15,600 annual rent.

    Personal name (Section 24)

    • Profit before mortgage interest: £15,600 − £1,500 (other costs) = £14,100
    • Taxable profit: £14,100 (interest not deductible)
    • Tax at 40%: £5,640
    • Less 20% mortgage interest credit: £9,900 × 20% = £1,980
    • Net tax: £3,660
    • After-tax cash: £14,100 − £9,900 − £3,660 = £540

    SPV (limited company)

    • Profit after mortgage interest: £14,100 − £9,900 = £4,200
    • Corporation tax at 19%–25%: £798–£1,050
    • Net company profit: £3,150–£3,402

    The SPV retains 6× more cash for reinvestment. Dividend tax on extraction is a separate consideration — money kept in the company to acquire more stock compounds materially faster.

    Lender-by-lender SPV pricing competitiveness

    • Paragon: Sharp on portfolio landlords (4+ properties); strong on HMO and MUFB.
    • Foundation Home Loans: Competitive on first-time landlord SPVs; flexible on director income.
    • Landbay: Automated underwriting; sharp on standard SPV cases; portfolio-friendly.
    • Kent Reliance: Broad appetite — HMO, MUFB, expat, first-time landlord SPV.
    • The Mortgage Works (TMW): Strong SPV range for both vanilla and HMO; Nationwide-owned reliability.
    • Aldermore: Solid SPV BTL range; portfolio underwriting.
    • Precise: Adverse-credit-friendly SPV BTL specialist.
    • Fleet Mortgages: Sharp on HMO, MUFB and limited company.
    • Molo: Digital-first SPV BTL; fast decisions.
    • Castle Trust: Specialist on complex SPV (multi-director, complex ownership).

    SPV setup essentials

    1. Incorporate at Companies House (£50, 24 hours online).
    2. Use a SIC code restricted to letting: 68209 (other letting), 68100 (buying/selling own real estate) or 68320 (management of real estate on a fee basis).
    3. Set up a business bank account — Lloyds, NatWest, HSBC, Starling, Tide all serve SPVs.
    4. Appoint an accountant familiar with property SPVs.
    5. Apply for the BTL mortgage in the SPV name — directors personally guarantee.

    ICR (Interest Coverage Ratio) at SPV pricing

    Limited companies generally enjoy basic-rate ICR treatment: rent must cover 125% of mortgage interest stressed at 5.5%. Worked example: SPV BTL at 75% LTV on a £250,000 property → £187,500 mortgage. Stressed interest at 5.5%: £10,313 annual / £859 monthly. 125% ICR rent needed: £1,074. If actual rent is £1,200, passes comfortably.

    Director income, age and credit

    • Minimum director income: usually £25,000–£30,000 personal income required. A handful of lenders (Foundation, Landbay) accept lower or no minimum.
    • Director age: mortgage typically to age 75–80 at term end.
    • Director credit: clean credit preferred. Specialist lenders (Precise, Vida) take adverse on director.

    Pros

    • Mortgage interest fully deductible against company profits.
    • Strong long-term portfolio scalability via retained profits.
    • Wider lender pool than 2017 — sharp competition.
    • SPV structure is fast and cheap to set up.
    • Better for higher-rate taxpayers and portfolio landlords.

    Cons

    • Rate premium of 0.10%–0.30% over personal-name BTL.
    • Director personal guarantees required on virtually all SPV BTL loans.
    • Annual filing costs (£500–£1,500 accountancy) eat into low-yield deals.
    • Extracting profit via dividends incurs personal dividend tax.
    • Existing personal-name properties can't be moved to an SPV without triggering SDLT and CGT.
