Setting Up a Ltd Company for Properties: Holding Company, Group Structure & SPV Explained

Who this is for: UK landlords and small developers deciding whether to buy in your own name, through a single limited company, or via a holding-company group with SPVs (Special Purpose Vehicles).

What you’ll get: plain-English explanations, how the structure actually works, the tax and lender bits people miss, and a simple checklist to sense-check before you incorporate.

Quick definitions (plain English)

SPV (Special Purpose Vehicle): a clean, dedicated limited company used only to hold or develop property. Many buy-to-let lenders prefer “clean” SPVs and will even ask for specific SIC codes (commonly 68100, 68201, 68209, 68320) when they underwrite limited-company BTL. themortgageworks.co.uk

Holding company / group: a parent company on top, with one or more SPV subsidiaries underneath (often one SPV per project or cluster). Benefits: ring-fencing of risk, cleaner exits (you can sell the shares of an SPV), and easier cash movement between companies. Costs: more admin, more paperwork, more to get wrong.

Limited company basics: you form the company with Companies House, then tell HMRC within 3 months when it becomes active for Corporation Tax. You file annual accounts and a confirmation statement every year. GOV.UK

When a holding company + SPVs makes sense

  • You want ring-fencing: each project sits in its own box so issues don’t leak across.
  • You want lender-friendly underwriting: clean SPV purpose + accepted SIC codes. themortgageworks.co.uk
  • You care about exit flexibility: it can be neater to sell the shares of an SPV than the property.
  • You’re planning succession: shares are easier to move around than bricks.

If you’ve got one lightly-geared rental and you’re a basic-rate taxpayer, the admin might outweigh the benefits. The section on “two number scenarios” below will help you feel the difference.

How to set up (short version)

  1. Decide the scope (single SPV now vs group from day one).
  2. Form the company or companies with Companies House. GOV.UK
  3. Choose lender-friendly SIC codes if borrowing via BTL lenders (e.g., 68100, 68201, 68209, 68320). themortgageworks.co.uk
  4. Register for Corporation Tax once active; open separate bank accounts. GOV.UK
  5. Paper the group properly: shareholders’ agreement, inter-company loan agreements, dividend policy, board minutes.
  6. Run it like a business: accounts, CT600, confirmation statement, inter-company records kept tidy. GOV.UK

Tax fundamentals you must model (before you incorporate)

  • Corporation Tax bands: as at 2025/26, small profits rate 19% up to £50k, main rate 25% above £250k, with marginal relief in between. GOV.UK
  • Mortgage interest treatment:
    • Individuals: the “Section 24” rules restrict finance-cost relief to a basic-rate tax credit (you can’t fully deduct interest from rental profit). GOV.UK
    • Companies: interest is generally a deductible expense against company profits (subject to the Corporate Interest Restriction, which only bites if group net interest exceeds £2m a year). GOV.UK
  • Transferring existing property into a company: expect SDLT charged on market value where parties are connected, and potential CGT personally. In limited cases, Incorporation Relief (TCGA s162) can defer CGT if you’re transferring a genuine property business into a company for shares. This is a facts-and-paperwork test. GOV.UK
  • Higher SDLT for companies: companies pay the higher rates for additional dwellings; and for residential purchases over £500,000 by certain corporate bodies, a flat 17% rate can apply unless a relief applies (e.g., property rental business relief). GOV.UK
  • VAT angle (commercial vs residential): most residential lets are VAT-exempt; many commercial property supplies are exempt unless you “opt to tax.” If you’re mixing assets in a group, check partial exemption and option-to-tax rules up front. GOV.UK
  • Director loans (s455): treating the company like a piggy bank can trigger a 33.75% temporary tax charge on loans to participators if not repaid on time. GOV.UK
  • ATED & “enveloped dwellings”: companies holding higher-value UK residential property should check ATED; reliefs exist for property rental businesses and developers, but you still need to file the relief declaration return. GOV.UK

🔎 Decision box: SPV vs personal ownership (quick comparison)

Use this to orient yourself, then jump into our spin-off for the full decision tree.

SPV (Ltd company)

  • Finance costs usually deductible in the company. Big for higher-rate, leveraged portfolios (CIR only bites above £2m net interest per group). GOV.UK
  • You pay Corporation Tax on profits and personal tax when you extract money (salary/dividends). Model both layers. GOV.UK
  • Often lender-friendly if your SPV has the accepted SIC codes and no mixed trading. themortgageworks.co.uk
  • More admin: accounts, CT600, confirmation statement and proper inter-company records. GOV.UK
  • Moving existing properties in can mean SDLT at market value and CGT unless reliefs apply. GOV.UK

Personal name

  • Simpler filings.
  • Section 24: finance-cost relief restricted to a basic-rate tax credit; hits higher-rate taxpayers hardest. GOV.UK
  • Mortgage products and criteria differ vs limited-company BTL.

✅ Pre-incorporation checklist (five-minute sanity pass)

  1. Your tax rate & leverage: if you’re higher-rate and using debt, company interest deductibility can move the needle; if you’re basic-rate and lightly geared, simplicity may win. GOV.UK
  2. Existing properties: model SDLT at market value and CGT for any transfers, and whether Incorporation Relief could apply (genuine business test). GOV.UK
  3. Lenders: confirm your SPV SIC codes match lender criteria before you incorporate. themortgageworks.co.uk
  4. Admin appetite: you’ll file accounts, CT600 and a yearly confirmation statement (there’s a fee), and keep inter-company paperwork tidy. GOV.UK
  5. VAT & property mix: residential rents are usually VAT-exempt; commercial may be exempt unless you opt to tax. Map this early if you’ll hold both. GOV.UK
  6. Director loans: avoid accidental s455 charges by agreeing a clear extraction plan (salary/dividends), not “temporary” loans. GOV.UK
  7. ATED & 17% SDLT check (high-value resi in companies): confirm if reliefs apply for a genuine property rental business and file the right return. GOV.UK

🏦 Lender mechanics (what underwriters actually look for)

  • Clean purpose SPV with accepted SIC codes (commonly 68100, 68201, 68209, 68320). Several major lenders publish these explicitly.
  • No mixed trading: keep other trading out of the SPV.
  • Personal guarantees & security: expect PGs and charges.
  • Evidence of separation: separate bank account, no cross-contamination with other businesses.
    (See The Mortgage Works’ limited-company criteria for accepted SIC codes; others are similar.) themortgageworks.co.uk

Compliance & costs (written out, no table)

  • Forming the company: online incorporation with Companies House; after incorporation you’ll get a UTR for tax. GOV.UK
  • Tell HMRC when active: you must register for Corporation Tax within 3 months of the company becoming active (starting its accounting period). GOV.UK
  • Annual accounts: file with Companies House within 9 months of year end (first set has a longer runway); file your Company Tax Return within 12 months of the period end; pay any Corporation Tax 9 months and 1 day after the period end. GOV.UK
  • Confirmation statement: file once a year and pay the £34 online fee; this confirms key company details and people with significant control. GOV.UK
  • Running a group: keep inter-company minutes and loan agreements in writing; record dividends and board decisions; keep separate bank accounts for each company; avoid “messy” cross-guarantees unless intended.
  • Professional costs: allow for bookkeeping, year-end accounts, CT600, and advice time (especially for SDLT/CGT modelling, VAT on property, and lender structuring).

Two quick number scenarios (sole income, 2025/26, illustrative only)

Assumes England/Wales/NI bands: Personal Allowance £12,570, 20% basic rate to £50,270, then 40%; Section 24 gives a 20% credit on finance costs (capped by HMRC rules).

Scenario A — One rental, low leverage (basic-rate overall)

  • Inputs: Rent £18,000; other costs £2,000; mortgage interest £3,000.
  • Property profit (before Section 24): £18,000 − £2,000 = £16,000.
  • Taxable income after PA: £16,000 − £12,570 = £3,430.
  • Income tax: 20% × £3,430 = £686.
  • Section 24 credit: 20% × £3,000 = £600 (applies in full). GOV.UK
  • Income tax due: £686 − £600 = £86.
  • Cash profit before tax: £18,000 − £2,000 − £3,000 = £13,000 → effective tax ≈ 0.7%.

(For comparison only: if this were inside a company and profits were retained, company profit would be £13,000 and CT at 19% ≈ £2,470; extraction taxes would then apply when you pay yourself.)

Scenario B — Growing portfolio, more leverage (nudges into higher rate)

  • Inputs: Rent £60,000; other costs £5,000; mortgage interest £20,000.
  • Property profit (before Section 24): £60,000 − £5,000 = £55,000.
  • Taxable income after PA: £55,000 − £12,570 = £42,430.
  • Income tax:
    • 20% on £37,700 = £7,540
    • 40% on £4,730 = £1,892
    • Total before credit = £9,432. GOV.UK
  • Section 24 credit: 20% × £20,000 = £4,000 (applies in full under HMRC caps). GOV.UK
  • Income tax due: £9,432 − £4,000 = £5,432.
  • Cash profit before tax: £60,000 − £5,000 − £20,000 = £35,000 → effective tax ≈ 15.5%.
  • Company profit (interest is deductible): £35,000.
  • Corporation Tax (small-profits rate 19%): £35,000 × 19% = £6,650.
  • Post-CT profit retained in the company: £28,350.
  • Then what? You decide how and when to extract (salary, dividends, or retain to fund the next deposit). For a plain-English walkthrough of the options, rates and NIC, see: How to Pay Yourself as a Limited Company Director (UK 2025/26).
  • Notes: thresholds can reduce if you have associated companies in a group, and if your group’s net interest > £2m, Corporate Interest Restriction may apply (most SMEs sit below this).

Takeaway: with sole income, Section 24 is softened by the Personal Allowance and the 20% band, so the gap to the company route narrows. The company keeps interest fully deductible (hence the clean £35k profit before CT), but remember you’ll face personal tax when you extract money (salary/dividends).

Where people go wrong (and how to avoid it)

  • Wrong or messy SIC codes / mixed trading: lenders want clean, purpose-built SPVs. Pick accepted SICs and keep other activities out. themortgageworks.co.uk
  • Assuming “company = always less tax”: you must model company tax plus your extraction taxes.
  • Transferring personally-owned properties without modelling SDLT & CGT: with connected parties, SDLT can apply on market value, even if no cash changes hands; Incorporation Relief only defers CGT if you’re truly moving a business. GOV.UK
  • Forgetting company-specific pitfalls: s455 on director loans, ATED on higher-value resi, and VAT/option-to-tax decisions on commercial. GOV.UK

FAQs

Is an SPV always better than owning in my own name?
No. If you’re basic-rate with little debt and want simplicity, personal ownership can be fine. SPVs tend to win for higher-rate taxpayers with leverage (company interest deductibility), and for those who value ring-fencing or share-sale exits. See our spin-off: Should You Hold Property in an SPV or Your Own Name? GOV.UK

What SIC codes do lenders accept for SPVs?
Commonly 68100, 68201, 68209, 68320, but check your chosen lender’s criteria before you incorporate.

If I move my rentals into a company, do I pay SDLT and CGT?
Often yes: SDLT can be due on market value (connected parties), and CGT may arise personally unless Incorporation Relief applies (business test, shares for consideration). Get tailored advice before you transfer. GOV.UK

Do companies pay the 3% SDLT surcharge and the 17% corporate rate?
Companies are generally within the higher additional-dwellings rates; and for residential purchases over £500,000 by certain corporate bodies, a 17% rate can apply unless a relief applies (for example, a qualifying property rental business). GOV.UK

Are residential rents subject to VAT?
Most residential lets are VAT-exempt. Commercial property can also be exempt unless you opt to tax which changes the VAT position and your input VAT recovery. GOV.UK
