A loan agreement is one of the most common commercial contracts a UK business will come across, whether the company is lending money to a director, borrowing from a shareholder, or dealing with a bank facility. Get the drafting right and everyone knows where they stand on repayment, interest, and what happens when things go wrong.
Get it wrong and you can end up arguing over terms that should have been spelled out on day one. This guide walks through what a company loan agreement actually does, the clauses that matter most, and some of the practical points directors often miss.
It is written for company owners, finance managers, and anyone reviewing a loan document before signing. The aim is to help you read a loan agreement with confidence rather than glazing over the legal paragraphs.
What this document is
A company loan agreement is a written contract that sets out the terms on which one party (the lender) hands over money to another party (the borrower), on the understanding that it will be paid back. In a company context, the borrower or the lender (or both) is a limited company, and the document is usually signed by a director on the company's behalf.
The agreement records the amount being lent, how and when it must be repaid, what interest is payable, and what rights the lender has if the borrower stops paying. It can be a short one-page facility between family members and their own company, or a lengthy institutional document running to dozens of pages.
Whatever the length, the purpose is the same: to turn an informal understanding into an enforceable contract that a court would recognise. For companies, a written agreement is also important for accounting, tax treatment, and, where directors are involved, for meeting the disclosure and approval rules in the Companies Act 2006.
How to use this document
Agree the commercial terms first. Before anyone opens a template, the parties need to settle the basics: how much is being lent, for how long, at what interest rate, and whether any security is being offered. Writing these down in a short term sheet avoids drafting a document that then has to be rewritten when someone changes their mind.
Check the company's authority to borrow or lend. Directors need to make sure the company's articles allow the transaction and that any required board resolution is passed. If the loan involves a director personally, shareholder approval may be required under the Companies Act 2006. This step is often skipped and causes problems later during audits or due diligence.
Draft the agreement with the key clauses. The document should cover the loan amount, interest, repayment dates, events of default, and remedies. It should also deal with practical matters such as how notices are served, which law governs the contract, and whether the lender can transfer the loan to someone else. Each clause should reflect what the parties actually agreed.
Deal with security and registration. If the loan is secured over company assets, such as property, shares, or a debenture over the whole business, the charge normally needs to be registered at Companies House within the statutory time limit. Missing the registration deadline can make the security void against other creditors, which defeats the point of taking it.
Sign, date, and keep proper records. Both parties should sign the agreement, and the company should keep a signed copy with its statutory books. Payments in and out should be recorded against the loan account, and any changes to the terms should be documented in writing rather than agreed by email or over the phone.
Q Does a company loan agreement have to be in writing?
Legally, a simple loan can be made verbally and still be enforceable, but relying on a handshake is asking for trouble. For any company loan, a written agreement is strongly recommended. It gives both sides certainty, supports the accounting entries, and provides evidence if there is ever a dispute about what was agreed. Auditors, HMRC, and future investors will also expect to see written documentation.
Q What interest rate should a company loan charge?
The parties can agree any rate they choose, provided it is not extortionate. For loans between connected parties, such as between a director and their company, HMRC may look at whether the rate is commercial. Charging no interest or a very low rate can sometimes trigger tax consequences. If there is no commercial benchmark, many parties use the Bank of England base rate plus a margin as a starting point.
Q What is an event of default?
An event of default is a situation defined in the agreement that allows the lender to take action, usually demanding immediate repayment of the whole loan. Typical events include missing a payment, breaching another clause in the agreement, becoming insolvent, or providing false information when the loan was taken out. The agreement should list these clearly so there is no argument later about whether a default has actually occurred.
Q Do I need to register a loan at Companies House?
The loan itself is not registered, but if the borrower grants security over its assets, such as a charge or debenture, that security normally needs to be registered at Companies House. Registration must happen within the statutory time limit, which is generally 21 days from creation of the charge. Failing to register on time can mean the security is unenforceable against a liquidator or other creditors.
Q Can a company lend money to one of its directors?
Yes, but the Companies Act 2006 places restrictions on loans to directors and connected persons. Shareholder approval is usually required, and certain disclosures must be made in the company's accounts. There can also be tax consequences under the rules on loans to participators in close companies. It is worth checking the position carefully before the money moves.
Q What happens if the borrower cannot repay?
The lender's options depend on what the agreement says. Remedies may include charging default interest, demanding immediate repayment of the whole balance, enforcing any security that has been granted, and ultimately bringing a claim in court. If the borrower is insolvent, the lender may need to prove in the liquidation or administration. Taking early legal guidance often preserves more options than waiting.
Q Can the terms of a loan agreement be changed later?
Yes, but any changes should be recorded in writing and signed by both parties, usually as a formal variation or side letter. Changes agreed only by email or conversation can create uncertainty and may not bind the parties. If the loan is secured, a variation may also affect the security, so the documentation should be reviewed carefully before anything is changed.
Loan agreements pull together interest, security, default rights, and repayment terms, and small wording choices can have real consequences if things go wrong later.
