5 Legal Risks That Quietly Scare Away UK Investors

Investors are not just backing an idea. They are backing the business behind it.

A strong pitch deck, growing revenue and a compelling product can get investors interested. But before they commit, serious investors usually look under the hood. They want to know whether the company owns its assets, has the right contracts in place, complies with the law and can scale without hidden legal problems.

For UK companies, these issues often surface during due diligence, when investors review Companies House filings, statutory registers, customer contracts, employment documents, intellectual property records and compliance materials. If the paperwork is missing, unclear or expensive to fix, it can delay a raise, reduce valuation or cause investors to walk away.

Here are five legal risks that can quietly make investors think twice.

1. Regulatory and compliance gaps

Investors want confidence that the business can operate legally as it grows.

This matters most in regulated industries such as health, financial services, food, education, childcare, employment agencies, consumer credit, cosmetics, alcohol, franchising, professional services and data-driven businesses. If the business needs licences, registrations, approvals, disclosures or industry-specific compliance processes, investors will usually want to see that these are in place.

A healthtech startup offering regulated health products, medical devices or therapeutic claims may need to consider medicines, medical devices and advertising rules. A food business selling packaged products may need to comply with food safety, labelling and consumer protection requirements. A fintech, lending, investment, cryptoasset or payments business may need to consider Financial Conduct Authority authorisation, anti-money laundering obligations, financial promotions rules or payment services regulation.

For online businesses, privacy and data protection can also become a serious issue. The UK GDPR and Data Protection Act 2018 regulate how businesses collect, use, store and disclose personal data. For the most serious infringements, the Information Commissioner’s Office can issue fines up to the higher maximum of £17.5 million or 4% of total worldwide annual turnover.

Consumer law is another major area. Under the Consumer Rights Act 2015, unfair terms in consumer contracts and notices are not binding on the consumer. The Digital Markets, Competition and Consumers Act 2024 has also updated UK consumer protection law, including unfair commercial practices rules that apply to commercial practices from 6 April 2025.

This is especially relevant for ecommerce, SaaS, marketplace, membership and online course businesses. Pricing disclosures, renewal processes, cancellation journeys, fake reviews and subscription terms are all areas investors may look at closely. The government has also consulted on the new subscription contracts regime under the DMCC Act, which is intended to strengthen consumer rights around subscription contracts.

The investor's concern is not just “has the business made a legal mistake?” It is: could this legal issue limit growth, trigger penalties, require a costly operational change or damage the brand after investment?

A business can often fix compliance gaps. But if the business model itself depends on risky claims, poor data practices or contracts that breach consumer law, investors may see that as a structural problem.

2. Weak contracts behind the business

Revenue looks much stronger when it is supported by clear contracts.

Many early-stage businesses rely on informal arrangements: email threads with customers, handshake deals with suppliers, unsigned proposals, vague contractor scopes or copied website terms. That may work in the early days, but it can become a problem when investors ask how reliable the business’s revenue and operations really are.

Investors usually want to see that key relationships are documented. This may include customer contracts, supplier agreements, contractor agreements, licence agreements, confidentiality agreements, website terms, subscription terms and service agreements.

The issue is not just whether a contract exists. It is whether the contract supports the business model.

For example, if a SaaS business has recurring revenue but no proper subscription terms, investors may ask how cancellations, refunds, liability, service outages and data use are handled. If an ecommerce business uses standard terms with broad one-sided clauses, there may be unfair contract terms risk. If an agency has major clients but no signed service agreements, revenue may look less reliable because there is no clear scope, payment obligation, termination process or limitation of liability.

Weak contracts can also create scaling problems. A business might win customers quickly, but if every deal is negotiated differently, the legal and operational burden grows. Investors often prefer businesses with repeatable, standardised contracts because they are easier to scale.

A marketplace is a good example. It might tell investors it earns commission on every transaction. But if its terms do not clearly explain the marketplace’s role, payment flow, liability position, refund obligations and user responsibilities, investors may worry that the business is taking on more risk than it realises.

Strong agreements do more than “protect” the business. They help prove that revenue, relationships and operations are commercially reliable.

3. Messy company structure or cap table

Investors need to know exactly what they are investing in.

That sounds simple, but many early-stage businesses have messy ownership histories. Founders may have split equity informally. A former founder may still hold shares. An adviser may have been promised equity over coffee. Early team members may expect options that were never documented. Companies House records may not match the company’s internal understanding.

These issues can become serious during due diligence.

Investors will usually compare the cap table in the pitch deck against the company’s statutory registers, Companies House filings, share certificates, option documents, shareholder approvals and any shareholders’ agreement. Under the Companies Act 2006, every company must keep a register of its members, so messy or inconsistent records can quickly become a due diligence issue.

If those records do not line up, investors may not know who owns the company, whether equity promises have been properly documented or whether new shares can be issued cleanly.

A messy cap table can also create uncertainty around control and dilution. Investors may ask whether there are pre-emption rights, drag-along rights, tag-along rights, consent rights or shareholder disputes that could block the investment or complicate a future exit.

For UK startups, investors may also ask about SEIS or EIS. These tax relief schemes can make early-stage investment more attractive, but eligibility depends on detailed rules about the company, the trade, the shares being issued and the investor. If a business has assumed it qualifies without checking the rules, or without seeking advance assurance where appropriate, that can create uncertainty during the raise. HMRC describes advance assurance as asking whether it agrees that an investment would meet the conditions of a venture capital scheme.

Some businesses also consider a group structure, where valuable IP or assets are held separately from the trading company. This can help manage risk in the right circumstances, but it is not necessary for every business. Investors mainly want the structure to be clear, suitable and properly documented.

The real-life consequence is straightforward: if investors cannot quickly understand who owns the company, where the key assets sit or whether the investment qualifies for expected tax relief, they may pause the deal until the structure is cleaned up. That can slow momentum at exactly the wrong time.

4. Unclear IP and asset ownership

For many businesses, intellectual property is the asset investors are really backing.

This can include trade marks, software, product designs, confidential information, website content, branding, customer materials, data, inventions, templates and creative assets. If the company does not clearly own these assets, investors may question what they are actually investing in.

One of the most common issues is contractor-created IP.

A business might pay a developer to build an app, a designer to create a logo, a photographer to take product images or a consultant to prepare key materials. But paying an invoice does not always mean the company owns all the IP outright. Ownership may depend on the contract, the circumstances and whether rights have been properly assigned.

That distinction can become critical.

If a SaaS company cannot prove it owns the code in its platform, investors may worry that the company cannot freely commercialise, modify, license or sell the product. If an ecommerce brand has built goodwill in a name but has not registered a trade mark, investors may worry about rebranding risk. If a creative business relies on course materials, templates or photography created by contractors, investors may ask whether the company has proper IP assignments.

Trade marks deserve special attention. Registering a company name at Companies House does not automatically protect the brand as a trade mark. A UK trade mark protects a brand, such as the name of a product or service, and trade marks are registered for particular goods and services.

For investors, this is not a technicality. If the business has spent years building a brand it cannot legally protect, or worse, a brand that infringes someone else’s rights, the business may face rebranding costs, disputes, lost goodwill and expansion problems.

The practical fix is usually to make sure key IP is identified, owned and documented. That may involve UK trade mark registration, IP assignment deeds, contractor agreements, developer agreements, confidentiality arrangements and clear records of who created what.

5. Employment and contractor issues

People risk can quickly become legal risk.

Investors may look at whether employees and contractors have proper written agreements, whether individuals have been classified correctly, whether key people have confidentiality and IP obligations, and whether the business has complied with employment law.

One common issue is employment status. In the UK, individuals may be employees, workers or self-employed contractors, and that status affects rights and responsibilities. GOV.UK lists the main types of employment status as worker, employee, self-employed and contractor, director and office holder. Courts and tribunals can make final decisions on employment status.

For contractors working through a personal service company or other intermediary, the off-payroll working rules, commonly known as IR35, may also be relevant. This is separate from ordinary employment status risk, but it can still matter during due diligence, especially for businesses that rely heavily on contractors.

This matters to investors because workforce risk can create hidden liabilities. A company may appear lean and efficient because it uses freelancers or contractors, but if those individuals are legally employees or workers, the business may face risks around holiday pay, National Minimum Wage, notice, tax, National Insurance and employment rights.

Employment documents also matter for IP and confidentiality. If a key developer, salesperson or product manager leaves, the company needs to know whether it owns the work they created, whether confidential information is protected, and whether there are reasonable restrictions around misuse of clients, code, strategy or trade secrets.

Another common issue is undocumented equity promises. Early team members may have been told they would “get shares later” or “receive options after the raise.” If those promises were never documented, they can create disputes at the exact moment investors are trying to clean up the cap table.

A practical example: a startup may tell investors that its platform is ready to scale. But if the main developer was engaged informally, owns parts of the code, has no confidentiality obligations and is threatening to leave, the investor may see the product as fragile.

Investors want to know the business can grow its team without creating disputes, hidden liabilities or ownership problems.

Why these risks matter

Investors are not expecting every business to be perfect. Most early-stage and growing businesses have legal gaps somewhere.

The real issue is whether those gaps are known, manageable and fixable.

Legal risk becomes a serious investor concern when it affects the core value of the business. That usually means risk around ownership, revenue, compliance, scalability or exit.

A missing low-value supplier agreement may be easy to fix. But unclear software ownership in a SaaS company, an unregistered or conflicting trade mark for a consumer brand, a messy cap table before a raise, or regulatory non-compliance in a health or financial services business can go directly to valuation.

The best time to fix these issues is before investors ask for documents. Once due diligence has started, missing agreements or unclear ownership can slow momentum and weaken negotiating power.

Before raising capital, it is worth reviewing the legal foundations of the business: company structure, cap table, key contracts, IP ownership, trade marks, employment arrangements, privacy practices and regulatory obligations.

Getting these foundations right does not just help with investment. It can also make the business easier to scale, sell, license, franchise or partner with in the future.
