Types Of Business Acquisitions: Common Acquisition Structures For UK SMEs

Buying another business can be one of the fastest ways to grow. Instead of building everything from scratch, you can acquire customers, a team, supplier relationships, systems, intellectual property (IP), and market share in one go.

But before you jump in, it’s worth slowing down long enough to pick the right acquisition structure. The acquisition type you choose can affect tax (you should always take specialist tax advice), risk, liabilities you inherit, employee transfer obligations, and how easy it is to walk away if something doesn’t check out.

In this guide, we’ll break down the most common acquisition types UK SMEs use, what they mean in practical terms, and what legal building blocks you’ll usually need to protect your business from day one.

What Do We Mean By “Types Of Acquisition”?

When people talk about “types of acquisition”, they’re usually talking about how the deal is structured legally.

At a high level, you’re typically doing one of these things:

• Buying the shares in a company (so you take over the company itself).
• Buying the assets of a business (so you take the parts you want, and often leave the rest behind).
• Combining businesses in a way that looks more like a merger or restructure.
• Buying a portion of a company (an investment with control rights, rather than a full takeover).

There isn’t one “best” structure for every SME. The right answer depends on what you’re buying (and why), what risks are acceptable, and how clean the target business is from a legal and compliance perspective.

One more thing: terms like “business purchase” and “acquisition” are often used interchangeably. In practice, most SME acquisitions are either a share purchase or an asset purchase, with additional documents layered around them.

Asset Purchase Acquisition (Buying Assets And Goodwill)

An asset purchase is where you buy specific business assets rather than buying the company that owns them.

This is one of the most common acquisition types for SMEs, particularly when:

• you only want certain parts of the business (eg the customer list, website, brand, equipment);
• you want to reduce the chance of inheriting unknown liabilities (eg old tax debts or historic disputes); or
• the seller is a sole trader or partnership (so there aren’t “shares” to buy).

What You Can (And Can’t) Buy In An Asset Purchase

In an asset purchase, you choose what’s included, such as:

• stock and equipment;
• contracts (supplier and customer contracts, where transferable);
• the trading name and brand assets;
• domain names and websites;
• customer databases (with care around UK GDPR compliance);
• IP (copyright, trade marks, designs, know-how);
• goodwill (the reputation/value of the trading business).

You don’t usually take on the seller’s historic debts and liabilities automatically, but some liabilities can still transfer or arise depending on what’s actually transferred, how you operate the business post-completion, and what the agreement and law require.

Key Legal Issues To Watch

• TUPE risk: employees may transfer across automatically under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE) if what you’re buying amounts to a “business transfer”. TUPE is technical and can be expensive to get wrong.
• Contract transfers: many contracts can’t be “assigned” without consent, or may require a formal novation.
• Data protection: if customer or mailing-list data is part of the deal, you’ll need to make sure there’s a lawful basis for transfer and proper notices/contract terms in place under the UK GDPR and Data Protection Act 2018.

In many SME deals, an asset purchase is documented through a Business Sale Agreement, with schedules listing the assets, transfer mechanics, and seller warranties.

Share Purchase Acquisition (Buying The Company)

A share purchase is where you buy shares in a limited company from its existing shareholders. Instead of cherry-picking assets, you take over the whole company (including what it owns, what it owes, and what it’s responsible for).

This is one of the most common acquisition types where the target has:

• valuable contracts that are hard to transfer;
• licences or accreditations held by the company;
• employees you want to retain with minimal disruption;
• valuable IP already owned by the company.

The Big Trade-Off: Simpler Transfers, More Inherited Risk

The appeal of a share purchase is that the business often continues seamlessly:

• customer and supplier contracts usually stay in place (because the contracting entity doesn’t change);
• assets remain owned by the same company;
• employees remain employed by the same company (so TUPE is usually less central, though you still need to manage employment law risks).

The downside is you may inherit historic liabilities you didn’t expect. That could include:

• tax liabilities (and you should take specialist tax advice on the structure and risks);
• ongoing disputes or claims;
• regulatory issues;
• poor HR practices (eg missing right to work checks, unclear contracts, unpaid holiday risk);
• data protection non-compliance.

This is why due diligence and the warranty/indemnity package matter so much in share purchases.

Documents You’ll Commonly Need

• Share Purchase Agreement (SPA): the main deal contract.
• Disclosure letter: where the seller discloses exceptions to warranties.
• Completion deliverables: board minutes, resignation letters, updated registers, etc.
• Post-completion protections: restrictive covenants (non-compete/non-solicit), transitional services, retention arrangements.

If the company will have multiple owners after completion (for example, you buy 70% and the founder keeps 30%), you’ll usually want a Shareholders Agreement to set out voting rights, reserved matters, exit rules, and what happens if relationships break down.

Merger-Style Acquisitions (Combining Two Businesses)

In the SME world, “merger” is often a commercial description rather than a strict legal category. In practice, a merger usually happens through one of the main structures (asset purchase or share purchase), plus an agreed plan for how the two businesses will operate going forward.

A merger-style acquisition can make sense where:

• two businesses have complementary services and want to cross-sell;
• you want to combine teams and reduce overheads;
• there’s a desire to “merge as equals” (even if one party is technically acquiring the other).

Common Merger Structures For SMEs

• One company buys the shares of the other (share purchase), then integrates operations.
• A new company is formed and both parties contribute shares/assets into it (a restructure).
• Asset transfer into one existing entity, with consideration paid in cash and/or shares.

Where a merger involves rolling equity (eg the seller receives shares in your company rather than cash), you’ll want to tighten up your internal governance documents. That might include updating the Company Constitution (articles of association) so it properly reflects new share rights, transfers, and decision-making.

If the merger is being driven by founders working closely together, it can also be smart to document roles, expectations, and exit triggers early in a Founders Agreement (even if you already “get along” today).

Management Buyouts (MBOs) And Employee-Led Acquisitions

A management buyout (MBO) is where the existing management team acquires the business (usually the shares), often using external funding.

Even if you’re not the manager buying the company, MBOs matter because they can show up in two common SME scenarios:

• You’re the owner selling to your management team as a clean succession plan.
• You’re a buyer competing with an MBO (and you need to understand how their deal structure might differ from yours).

How An MBO Is Usually Structured

• Share purchase funded by a mix of savings, bank finance, investor funding, and/or vendor finance (where the seller is paid over time).
• Newco acquisition: a new company is set up by management to buy the shares (often to ring-fence risk and manage funding).

Legal Points SMEs Often Miss In MBOs

• Conflicts of interest: managers owe duties to the company, so the process needs to be handled carefully and transparently.
• Security and guarantees: lenders may require personal guarantees or security over assets.
• Employment status changes: managers become owners, which affects incentives, restraints, and decision-making.

Because MBOs can be document-heavy, it’s common to run the transaction through a structured Legal Due Diligence Package so the buyer (and funders) have confidence in what they’re taking on.

Acqui-Hires And IP-Focused Acquisitions (Buying The Team Or Tech)

Sometimes you’re not acquiring a business for its revenue at all. You’re acquiring it for its people or its IP.

This type of acquisition is common in service businesses, agencies, and tech-enabled SMEs where the real value sits in:

• the leadership team and key staff;
• software, content, or product IP;
• processes and know-how;
• a brand and audience.

Two Common Ways To Structure An Acqui-Hire

• Share purchase (simple continuity, but you inherit liabilities).
• Asset purchase (you buy IP and selected assets, then hire the people you want, subject to TUPE risk if the “business” transfers).

Key Legal Focus Areas

With team/IP-driven acquisitions, you’ll usually want to pay extra attention to:

• IP ownership: is the IP actually owned by the company, or does it sit with a founder/contractor? If it’s unclear, you may need an IP Assignment so the value you’re paying for is properly transferred.
• Retention: if the whole point is the team, you’ll likely need new incentive arrangements and clear Employment Contract terms (including confidentiality and post-termination restrictions where appropriate).
• Confidential information: make sure confidentiality obligations and handover expectations are documented (especially if the seller remains in the industry).

Where existing commercial contracts need to move to your entity (or to a new group company), you may need a Deed of Novation so the contract is properly transferred with all parties’ consent, rather than relying on informal arrangements that can unravel later.

How Do You Choose The Right Acquisition Structure As An SME?

If you’re weighing up different types of acquisition, it helps to start with your commercial goal and work backwards.

Ask Yourself These Practical Questions

• Do you want the whole business, or just parts of it? If you only want certain assets, an asset purchase might be the cleanest route.
• Are there key contracts that must stay in place? If contracts can’t be easily transferred, a share purchase might be more practical.
• How comfortable are you with inherited liability? Share purchases can carry more hidden risk unless diligence and warranties are strong.
• Are employees central to the value? You’ll need to think about TUPE, retention, and HR compliance either way.
• Is the business regulated or licence-dependent? Sometimes licences don’t transfer easily in an asset sale.
• Is the seller staying involved? If yes, you’ll likely need ongoing governance documents and clear role expectations.

A Note On Due Diligence (And Why It’s Not Just A Box-Ticking Exercise)

Due diligence is your chance to confirm the target business is what it claims to be.

For SMEs, diligence usually focuses on high-impact areas like:

• company structure and ownership;
• material customer/supplier contracts and termination rights;
• employment arrangements and potential disputes;
• IP ownership and infringement risks;
• data protection compliance (especially if personal data is a key asset);
• any litigation, complaints, or regulatory issues.

Even if you’re doing a smaller deal, it’s worth getting the key documents reviewed properly. It’s often far cheaper to negotiate protections upfront than to fight about them after completion. This is where a targeted Contract Review can make a real difference to your risk profile.

Key Takeaways

• The main types of acquisition for UK SMEs are typically asset purchases (buying selected assets and goodwill) and share purchases (buying the company itself).
• Asset purchases can reduce inherited liabilities, but you’ll need to manage contract transfers, possible TUPE issues, and data/IP transfers carefully.
• Share purchases can be operationally smoother (contracts and employees often stay in place), but you may inherit historic liabilities, so due diligence and warranties matter.
• Merger-style acquisitions often involve additional governance work, especially where consideration includes shares or the seller stays involved.
• MBOs and acqui-hires are common in the SME world, but they require careful planning around funding, conflicts, IP ownership, and retention.
• Whichever structure you choose, the right contracts and legal checks upfront will help protect your business and keep the deal on track.
