Demerger Examples in the UK: Six Owner-Managed Company Scenarios

Quick answer: Typical UK demergers by owner-managed companies fall into six patterns: property moved out of a trading company, a trade separated before a sale, two businesses given to different family members, shareholders who part ways, surplus cash or investments taken out, and a risky activity ring-fenced. The route usually follows the facts. A capital reduction demerger suits most, a statutory demerger suits two genuine trades, and a liquidation demerger suits thin reserves.

Every scenario below is hypothetical and simplified. It is not a client case, and the figures are round numbers chosen to illustrate the point.

Why most demerger examples are not much use

Search for demerger examples and you find large listed groups splitting off a division. Their shares are quoted, their shareholders number in the thousands and the process is run by teams of lawyers.

Owner-managed companies are different. There may be two or three shareholders, one property, a single trade and a family relationship. The tax issues are the same in principle: capital gains tax, income tax, stamp duty and stamp duty land tax (SDLT). The practical questions are different. Who needs to agree? Is there enough in the reserves? What does the lender say?

For the three routes in detail, see our article on capital reduction, statutory or liquidation demergers. The examples below show where each tends to fit.

Example 1: The property comes out of the trading company

A manufacturing company owns its factory, which has risen in value. The owners want to protect the building from trading creditors and make the company cleaner for a future sale.

Route. A capital reduction demerger. The property moves to a new company that issues shares to the existing company, and those shares are then distributed to the shareholders. The property business is investment, so the statutory route is not available.

What decides it. Stamp duty land tax. A transfer of land between companies can create a charge based on market value. Group relief, reconstruction relief or keeping the property where it is and moving the shares are the usual ways to deal with it. Our article on SDLT traps in a property demerger explains them. Lender consent also matters, which we cover in demerging a company with mortgaged property.

Example 2: One trade is to be sold, the other kept

A company runs a building firm and a letting agency. A buyer wants only the letting agency. The owners want to keep the building firm.

Route. If both are genuine trades and the conditions are met, a statutory demerger can work. But if the sale to the buyer is already agreed, the statutory conditions are a problem, because they require that there are no arrangements for a sale. A capital reduction demerger, with the sale disclosed in the clearance application, is the more usual answer.

What decides it. The sale timetable. HMRC will look at whether the demerger is part of a sale plan. Disclose it, plan the order of steps and expect questions about the main purpose test that has applied since 26 November 2025. We cover what HMRC looks for in our clearance article.

Example 3: Two children, two businesses

A family company has a retail trade and a distribution trade. One child works in each. The parents want each child to own their business outright.

Route. A capital reduction demerger or, if the conditions are met, a statutory demerger. Where each shareholder ends up with a different company, the shareholdings will no longer be mirror images. That affects the stamp duty reliefs and needs careful planning.

What decides it. Whether the split is fair. The two businesses must be valued properly. If one is worth more than the other, an equalising payment or a different share allocation may be needed, and any cash changes the tax analysis.

Example 4: Shareholders who no longer want to work together

Two unrelated shareholders own a company that has a trade and a rental property. One wants the trade. The other wants the property.

Route. A partition demerger. The trade goes into one company, the property into another, and each shareholder ends up owning one company outright. It is a special case of the capital reduction approach, with the shares of the old company often cancelled for the departing shareholder.

What decides it. Agreement, and a fair valuation. A partition needs everyone to sign up. If they cannot agree, the alternatives are a buy-out, a sale or, in the worst case, a dispute. We cover this in more depth in our guide to splitting a company.

Example 5: Surplus cash and investments sitting in the trade

A company has built up cash and an investment portfolio alongside its main trade. The business is now worth more as a trading business than as a mixed one, and the owners would like to keep the trade looking clean.

Route. Often a capital reduction demerger into an investment company. The company is then free of the surplus assets. The alternative is to move the cash up to a holding company by dividend, which may be simpler and cheaper where there is a holding company already in place.

What decides it. Reserves, and the rules on trading status. HMRC uses a rough 20% test for non-trading activity when looking at reliefs such as Business Asset Disposal Relief and the substantial shareholding exemption. Keeping the surplus within safe limits is the purpose of the exercise.

Example 6: A risky activity ring-fenced

A company mostly does safe work, but one division takes on higher-risk contracts. The owners want a legal wall between the two.

Route. The division moves into a subsidiary under a holding company, or is demerged into a sister company. A demerger makes the companies independent. A subsidiary keeps the group together. The choice depends on whether the owners want shared ownership to continue, which is typically so.

What decides it. Whether a demerger is needed at all. A simple share exchange to insert a holding company can achieve a lot without a demerger. See our service page on corporate restructuring for the options.

What the examples have in common

• A clear commercial reason, written down.
• Enough value and reserves for the route.
• All shareholders, lenders and landlords on board.
• HMRC clearances considered before anything irreversible happens.
• A plan for what happens after the demerger, including any sale.

Example: A company is owned equally by two directors. It holds a trade worth £1.2 million and a property worth £800,000. They propose a capital reduction demerger so that each owns 50% of the trade company and 50% of the property company. If the arrangements are cleared and the steps are followed, there should be no gain on the shareholders and no charge on the company, and the position would be tax-neutral. Without the reliefs, the transfer of the property alone could trigger a corporation tax charge on the gain and SDLT on £800,000. The figures are hypothetical and the result depends on the facts.

FAQs

What is a real example of a demerger in the UK?

The best-known recent example is a listed group splitting off a division to its shareholders. For owner-managed companies, examples are normally private and confidential, which is why we describe typical patterns rather than naming clients.

Which type of demerger is most common for private companies?

The capital reduction demerger, because it can move property and investments as well as trades. A statutory demerger is limited to trading companies and has five-year conditions. A liquidation demerger is used mainly where reserves are low.

Can I demerge just one asset?

Yes. A single property or a business line can be moved to a new company and the shares distributed. The tax reliefs depend on what the asset is and how it is moved.

Does a demerger always need HMRC clearance?

No. Clearance is voluntary. But the cost of getting it wrong can be much larger than the cost of applying. The usual clearances are sections 138 and 139(5) TCGA 1992, section 701 ITA 2007 and, for a statutory demerger, section 1091 CTA 2010.

Is a demerger the same as a sale?

No. In a demerger the owners keep what they own, divided between companies. A sale gives up ownership. A demerger can also be a first step before a sale of one company.
