Corporate Loans: Legal Essentials for Companies Lending or Borrowing Funds

Almost every business - from startups to long-established companies - will find themselves on either side of a corporate loan at some stage. Maybe you’re searching for funding to take your business to the next level, or perhaps you’re considering lending surplus funds to another company as an investment opportunity. Whichever path you’re on, company in loan arrangements can unlock real growth and flexibility - but can also pose significant legal headaches if things go wrong.

So, how can you make sure your company in loan dealings are set up safely and designed to protect you from risk, now and in the future? In this guide, we’ll break down everything you need to know about company loans and provide practical, plain-English legal advice. You’ll learn how company-to-company loans work, the must-have legal documents, the regulations governing business lending in the UK, and how to sidestep common pitfalls.

Let’s make sure your business is protected and compliant from day one - keep reading for all the essentials.

What Is A Company In Loan And How Does It Work?

A company in loan is simply when one business lends money to another, rather than the loan involving a bank or traditional lending institution. It might be between group companies (for example, a parent company lending to its subsidiary), two unrelated companies, or even from a shareholder’s company to another venture.

The arrangements can vary in scale and complexity, but there are two main scenarios:

• Borrowing: Your company takes out a loan from another business and will need to repay the sum (with interest, usually) on the terms you agree. The funds might help with cash flow, expansion, new equipment, or investing in fresh opportunities.
• Lending: Your company provides a loan to another business, expecting to be repaid according to the contract. This could be an investment, a way of helping out a trading partner, or funding a related company in your group structure.

While loans between companies can be more flexible and tailored than dealing with banks, don’t make the mistake of treating them casually - legally, they’re complex and there’s a lot at stake!

Why Does Your Business Need A Properly Drafted Loan Agreement?

It’s tempting to think a handshake or a few emails is enough if you know the other business or they’re part of your group - but that’s a fast track to disputes and uncertainty.

A formal, professionally drafted loan agreement is essential because it will:

• Clearly set out the terms: how much is being loaned, interest rate, repayment schedule, and what happens if payments are missed
• Allocate responsibility for costs, fees, and tax treatment
• Include protection for the lender through security over assets (if agreed)
• Manage risk by including clauses that address default, early repayment, or disputes
• Help meet your obligations under UK laws and regulations

A robust loan agreement can mean the difference between smooth business growth and a costly legal battle. Avoid generic templates - loans need to be tailored to your company’s needs, your deal, and any agreed security. That’s where expert legal advice comes into play.

What Legal Documents Do You Need For A Company In Loan Arrangement?

The main document you’ll need - and the one you really cannot afford to skip - is the business loan agreement (sometimes called a commercial loan agreement or an intercompany loan agreement).

Depending on your arrangement, you might also need:

• Security documents - e.g., a debenture, legal charge, or fixed or floating charge over company assets, which allow the lender to recover their money if the borrower defaults.
• Board or shareholder resolutions authorising the loan (especially if you’re dealing with company directors’ duties).
• Personal guarantees if required - this is common where a lender wants extra security from the directors or shareholders of the borrowing company.
• Directors’ certificates or confirmations (sometimes needed for evidencing authority or confirming solvency).

If you’re lending to or borrowing from companies within the same group, there may be additional compliance or tax documents required - especially if you plan on writing off the loan, converting it into equity, or structuring it long-term.

It all starts with the contract, so check out our company contract management guide for more insight on the importance of getting agreements right.

What Are The Regulatory And Tax Considerations?

Loaning money between companies isn’t as simple as it sounds - there are legal hurdles, and you can quickly run into trouble with regulators and HMRC if you’re not careful.

Here are the main areas to keep on your radar:

• Regulated activities: In most straightforward company in loan arrangements (like intra-group loans or commercial deals), you don’t need FCA authorisation. But if lending becomes regular, large-scale, or looks like providing finance to consumers (as opposed to businesses), you might be conducting regulated activity and need specific permissions from the Financial Conduct Authority.
• Corporation Tax: Both the lender and borrower need to consider the tax impact of any interest charged and received, how it’s recorded, possible reliefs for bad debts, and withholding tax (if international).
• Director duties and company powers: If your company is lending or borrowing, directors must act in the best interests of the company and follow UK company law. This is especially critical where the transactions are not “arm’s length” - for example, if directors stand to benefit personally, or parent and subsidiary companies are involved. Get clear board resolutions in place and ensure compliance.
• Stamp Duty: If security is taken over assets, there could be stamp duty or filing requirements.

Tax and regulatory issues can trip up even experienced business owners, so it’s always wise to speak to a legal or tax expert before finalising a company in loan.

Are There Any Risks Or Pitfalls In Company Lending?

Yes - and they can be significant. Here are the top company in loan risks you need to watch out for, whether you’re the borrower or lender:

• Unclear or missing terms - Without a thorough loan agreement, it’s hard to enforce payment, claim interest, or pursue security if something goes wrong.
• Director liability - Company directors can be personally liable if they act outside their authority or breach their duties when making or approving loans.
• Debtor insolvency - If you’re lending funds and the borrower company goes bust, it can be hard to recover the money unless you have security. Always consider what protection is in place, and whether you’re prepared to lose the money if things don’t work out.
• Hidden conflicts or lack of approval - Lenders and borrowers within the same group, or with overlapping directors/shareholders, need to ensure all parties properly approve the deal to avoid legal or regulatory issues.

If in doubt, it’s far safer to get a contract specialist to review your deal before signing - a small investment now can save you a fortune down the line.

How Do You Structure Security For A Company In Loan?

Security is how a lender protects their position if the borrower doesn’t pay up. In company loan transactions, common security options include:

• Charges over assets - including fixed or floating charges on equipment, inventory, cash, or property
• Debenture - a broad security over all company assets, registered at Companies House
• Personal guarantee - directors or shareholders personally guarantee the repayment

Security needs to be arranged before the loan is advanced - don’t try to sort it later if you want real protection. Security agreements often need to be registered with Companies House within 21 days to ensure their enforceability against other creditors.

Why does it matter? If you don’t have registered security and the borrowing company becomes insolvent, you may be left with nothing - secured creditors get paid first, and unsecured creditors often lose out.

What Does A Commercial Loan Agreement Actually Cover?

A professionally drafted loan agreement isn’t just a formality; it’s your rulebook if things go south. Some of the key clauses include:

• Principal amount - the sum loaned
• Interest rate - fixed, variable, or zero-interest
• Repayment schedule - e.g., monthly, quarterly, lump sum, or bullet repayment
• Default and remedies - what happens if a payment is missed or late
• Security or guarantees - assets pledged as collateral or personal undertakings
• Event of default - what specific triggers (like insolvency, missed payments) allow the lender to demand immediate repayment or enforce security
• Prepayment terms - can the borrower repay early (and is there a penalty or incentive?)
• Regulatory and compliance confirmations - confirming both companies have authority, all necessary board resolutions have been passed, etc.

Getting this agreement right isn’t about box-ticking - it’s the best way to make your contract legally enforceable and avoid dead-ends in court.

Are There Alternatives To Traditional Company In Loan Structures?

Loans aren’t the only option when moving or raising funds between companies. You might consider:

• Share subscription agreements - issuing shares in exchange for capital
• SAFE notes (Simple Agreement for Future Equity) or convertible notes - loan-like instruments that convert to shares on certain triggers
• Debt-based crowdfunding - multiple entities lend small amounts to one business

Each option brings its own legal considerations around company law, regulation, and tax. It’s also possible to work with venture capital investors or enter more complex financing deals. Whatever path you pick, a legal expert can help you compare risks, pros and cons.

What Steps Should You Follow For A Legally Sound Company In Loan?

Here’s a quick checklist for setting up your company in loan the right way:

1. Plan clearly - Work out the business purpose, repayment ability, and whether a loan is the right tool.
2. Agree the terms - Interest rate, repayment, default triggers, security, and any permissions your company constitution may require.
3. Draft a proper loan agreement - Don’t rely on emails or handshake deals; get everything in writing, tailored to your needs.
4. Secure approval - Ensure all necessary board and (if applicable) shareholder approvals are properly recorded.
5. Register security - If offering or taking security, file the charge at Companies House promptly.
6. Monitor and report - Set up reminders for repayments and interest, keep records for audit and tax.
7. Review tax/regulation - Speak to an expert to make sure you don’t fall foul of HMRC or FCA rules.
