Loan agreement template UK: what makes a personal loan enforceable

A loan agreement records money lent and the terms on which it must be repaid. Under the law of England and Wales a loan between two individuals is enforceable without any special formality — but if the terms are not written down, disputes turn into one person's word against another's about whether the money was a loan or a gift. A workable agreement sets out five things: the amount and when it is advanced, the interest, the repayment schedule, what counts as default, and any security or guarantor.

What to include

1. The parties and the amount. Full names and addresses of lender and borrower, the sum lent, and the date it is advanced. If the money has already changed hands, say so and give the date.

2. Interest — including none. State expressly whether the loan is interest-free, carries a fixed rate, or a stated APR, and how interest is calculated and applied. "Interest-free" written down prevents a later claim that interest was assumed.

3. Repayment. Three usual shapes: a lump sum on a fixed date, instalments (amount, frequency, first and final dates), or on demand. On-demand loans are simple to draft but leave the borrower without certainty, so a reasonable period after demand is worth stating.

4. Early repayment. Whether the borrower may repay early, and whether interest is adjusted. Silence causes arguments in exactly the situation everyone wants — the borrower coming into money.

5. Default and demand. What triggers default (missed payment, insolvency, breach), whether the whole balance becomes payable immediately, and whether default interest applies.

6. Security or a guarantor, if any. A guarantee must be in writing and signed by the guarantor to be enforceable. If security over an asset is intended, take advice: charges over land or company assets have registration requirements that a simple agreement will not satisfy.

7. Governing law and signatures. Law of England and Wales, dated signatures from both parties, ideally witnessed.

When your loan becomes regulated

This is the part most templates ignore. If a business lends to an individual, the agreement may be a regulated consumer credit agreement under the Consumer Credit Act 1974. Regulated lending requires FCA authorisation and prescribed pre-contract information, and an unauthorised regulated agreement can be unenforceable without a court order. A one-off loan between friends or family is not caught; lending in the course of a business is a different matter, and worth advice before the money moves.

Also relevant even outside regulated lending: a very high interest rate can be challenged as an unfair relationship under the Act. If the rate looks punitive, expect it to be tested.

Practical points that decide whether you get repaid

• Pay by bank transfer, with a reference. Cash with no trace is the hardest kind of loan to prove.
• Match the paperwork to the transfer. Same amount, same date. Mismatches are what defendants build on.
• Keep the schedule realistic. An instalment plan that exceeds what the borrower earns produces default, not repayment.
• Family loans still need documents. The awkward conversation before the money moves is shorter than the one after it does not come back.
• Consider the limitation period. A simple contract claim in England and Wales generally must be brought within six years of the cause of action. Do not leave an unpaid loan drifting indefinitely.

Generate the agreement

Our template covers loans between individuals or businesses under the law of England and Wales: amount and advance date, interest (none, fixed or APR), repayment as a lump sum, instalments or on demand, early repayment, default and demand, optional security or guarantor — with checks that flag impossible dates, instalments larger than the loan, and interest levels or business-to-consumer lending that may bring the Consumer Credit Act into play.
