Incorporation & Company Structures

The essentials

When incorporation makes sense for landlords

Incorporating a property portfolio into a limited company is most beneficial for higher-rate taxpayers with significant mortgage debt. Since Section 24 removed individual landlords' ability to deduct mortgage interest, companies, which still deduct finance costs before corporation tax at 25%, can offer substantial annual savings.

Incorporation tends to work best for landlords who plan to retain profits within the company rather than extract them immediately. If you rely on rental income for day-to-day living expenses, the additional costs of extracting funds via salary or dividends may reduce the advantage. A detailed tax comparison modelling at least 10 years of projected income is essential before committing.

Limited company vs SPV structures

A special purpose vehicle (SPV) is a limited company set up solely to hold property. Most buy-to-let mortgage lenders prefer SPV structures with SIC code 68100 (buying and selling of own real estate) or 68209 (letting of own property). An SPV keeps property assets ring-fenced from other business activities, simplifying accounting and lending.

A trading limited company can also hold property, but lenders may apply stricter criteria and higher interest rates. For new purchases, an SPV is almost always the preferred route. For existing portfolios being incorporated, the choice depends on whether you have other business activities that could benefit from being combined.

Holdover relief and stamp duty on transfer

Transferring properties from personal ownership to a company is a disposal for capital gains tax purposes, triggering CGT on any gains at 18% or 24%. However, HMRC incorporation relief under TCGA 1992 s162 may apply if the portfolio qualifies as a business, typically requiring active management of multiple properties rather than passive holding.

Stamp duty land tax (SDLT) applies on the market value of the transferred properties, including the 3% additional dwelling supplement. For large portfolios this can represent a significant upfront cost. Some landlords phase incorporations or use partnership structures as an intermediate step to manage these costs.

Director loan accounts and dividend extraction

When you transfer properties to your company, the market value less any mortgages creates a director's loan account, money the company owes you. You can withdraw this balance tax-free over time, providing a useful source of income in the early years of incorporation without triggering additional tax.

Once the loan account is exhausted, profits are typically extracted via a combination of salary (up to the NIC threshold) and dividends. For the 2026/27 tax year, the dividend allowance is £500 and rates are 10.75% (basic), 35.75% (higher), and 39.35% (additional). Planning the mix of salary and dividends each year is critical to minimising the overall tax burden.

Choosing the right structure for your portfolio

The right structure depends on your portfolio size, mortgage levels, income needs, and long-term plans. Landlords building a portfolio to pass to the next generation may benefit from a family investment company (FIC), which offers flexible share classes and inheritance tax planning. Those focused on short-term cash flow may prefer to remain as individuals and use other Section 24 mitigation strategies.

There is no one-size-fits-all answer. A specialist property tax accountant can model the scenarios (personal ownership, SPV, trading company, partnership, or FIC) against your actual numbers and help you choose the structure that delivers the best outcome over the life of your portfolio.

Are Landlords Really Leaving? The Net Formation Data

Almost every article answering "are landlords selling up" runs on a survey. This one runs on the Companies House register. Over the twelve settled months to June 2026, property companies were incorporated 90,390 times and dissolved 45,622 times, a net gain of 44,768 companies. In the same window gross formations fell 2.6% year on year and the headline buy-to-let code was down 20.1% in the latest settled month alone. Both facts are true at once: fewer new companies than at the 2025 peak, and a population that is still growing. This page sets out the monthly net formation series, explains why individual landlords can be selling while the company sector expands, and states plainly what the register cannot tell you.

How to Change a SIC Code at Companies House for a Property Company

A SIC code is changed through the confirmation statement, not through a separate form or application. You can wait for the annual renewal or file an updating confirmation statement at any time to correct the codes early, and if the annual payment period is already paid for, that updating statement carries no further fee. This guide covers the filing mechanics, the £50 online and £110 paper confirmation statement fee, adding a code rather than replacing one, the four-code limit, timing around a mortgage application, and what happens on the public register once the change is accepted.

Do Landlords Incorporate When House Prices Fall? What the Data Shows

We tested our own incorporation series against the UK House Price Index across the 118 months from September 2016 to June 2026 and found essentially nothing: a correlation of 0.008 between the two year-on-year series. During the only sustained price fall in the window, from July 2023 to April 2024, incorporations were not falling with prices but accelerating, reaching more than 50 per cent year-on-year growth in April 2024. The turning points in the incorporation series line up with tax events instead. This piece sets out the method so you can reproduce it, gives the year-by-year table, and explains what actually moves the number.

How Many Buy-to-Let Limited Companies Are There in the UK?

At the Companies House bulk snapshot of 1 September 2026 there were 665,645 live companies on the UK register carrying one of the four real-estate SIC codes we track (68100, 68201, 68209 and 68320). That is the stock: every property company still registered, not the number formed last year. London holds 224,647 of them, 33.7% of the register, and roughly a third of the whole live population was incorporated within the last three years. This page sets out the count, how it splits by region, how old those companies are, and why our figure is larger than the buy-to-let company totals quoted elsewhere.

How Long Do UK Property Companies Last? The Age Profile of the Register

Sort the 665,645 live UK property companies on the register by the year each was incorporated and the shape is lopsided: this is a young population. Just under a third were incorporated in 2024 or later, roughly three quarters in the last ten calendar years, and the median company on the register dates from 2021. Only about one in seven predates 2010. This page sets out that age profile band by band, explains what it says about the population of landlord companies, and is honest about the one question the data cannot answer: a live register cannot tell you the average lifespan of a company, because every company that has already died is missing from it.

Landlord Registration for a Limited Company: Scotland and Wales

England runs no national landlord register, but Scotland and Wales both do, and neither one goes away because the property sits inside a limited company. Scotland's scheme is compulsory before letting, costs £85 plus £20 per property, runs on a 3-year cycle and carries a fine of up to £50,000 for letting unregistered. Rent Smart Wales splits the duty in two, registration and licensing, and states plainly that where a company is the landlord it is the company that gets registered, on its Companies House number, for 5 years at £60 online. This guide sets the two regimes side by side for a corporate owner, marks the points that the registers do not publish, and says where to get those confirmed.

What Section 24 Actually Did to Company Formations

Almost everything written about Section 24 argues the mechanism. This page measures the response instead. Using our own count of Companies House incorporations, landlord company formations on SIC 68209 rose from 19,733 in 2016 to 69,039 in 2025, a 3.5 times increase, while the wider four-code property union series went from 33,040 to 95,140. The steepest single jump lands inside the Section 24 phase-in window, the growth continued long after the restriction was fully in force, and the settled data through June 2026 now shows the first sustained deceleration in a decade. Figures are ours, from the UK SPV Incorporation Index, settled to 2026-06.

SPV Company Name Rules UK: What Companies House Accepts

A property SPV must end in Limited or Ltd, must not be the same as an existing registered name once Companies House strips out suffixes, punctuation and words like UK, and must not use a sensitive word without approval. Ordinary property words (property, investments, holdings, estates, portfolio) are not sensitive and are free to use. A name accepted at registration can still be ordered changed if it is too like an existing name, but only within 12 months. Changing a name later costs £20 online, £30 on paper, or £85 same-day, and is decided by a members' special resolution.

How to Cite the UK SPV Incorporation Index

The UK SPV Incorporation Index is a monthly count of UK property company incorporations built entirely from Companies House open data, published free for anyone to quote. This page is the reference card: what the index measures, the current headline figures with their period and definition, the method in plain English, the copy-paste citation line, the CSV download, the Open Government Licence terms and the monthly refresh cadence. It does not interpret the numbers. The charts, the trend commentary and the year-on-year reads live on the index page itself.

Where Property Companies Are Being Formed: The Regional Data

London accounts for 35.3% of all UK property company formations in the twelve months to August 2026, more than three times the next region. This page sets out the full regional split by share of formations, using registered-office postcodes from the Companies House bulk register, and compares each region's share in the first twelve months of a 36-month window against the last twelve so you can see who gained ground and who lost it. The movements are small but consistent: the North West, West Midlands and Scotland are taking a slightly larger slice, the South East, South West and East of England a slightly smaller one. Read every figure here as a share, not as a regional count.

Director Living in a Property Owned by a Limited Company

Yes, a director can live in a property their limited company owns, but the tax treatment is punitive unless full market rent is paid. Rent-free or below-market-rent occupation is a living-accommodation benefit in kind under ITEPA 2003 Part 3 Chapter 5 (ss.97-113), valued as the annual value of the property plus, where the property cost more than £75,000, an additional charge of the official rate of interest on the excess. The charge is reported on a P11D and carries employer Class 1A National Insurance. Occupation by a director also breaks the ATED rental-property relief, can create a section 455 charge if unpaid rent sits in the director's loan account, and is very likely to breach a buy-to-let mortgage.
