Client Cancelled Your Contract? Your Rights as a Contractor

Working Out What You Are Owed

Once you know whether the cancellation was permitted or a breach, you can work out the money. Depending on the circumstances, you may be entitled to recover:

• Payment for work already completed. If you have delivered part of the project, you are generally entitled to be paid for that portion, whether the cancellation was lawful or not.
• Payment for the notice period. Where the contract requires notice and the client did not give it, the value of that notice period is often recoverable.
• An agreed cancellation fee. If your contract specifies one, that sum becomes payable.
• Loss of profit on the remaining work. In a breach situation, you may claim the profit you would have made on the rest of the contract, reduced by anything you save in unincurred costs and by earnings from replacement work.
• Wasted expenditure. Costs you incurred specifically for the project, such as materials bought or subcontractors booked, may be recoverable if they cannot be reused or cancelled.

A word of caution on cancellation fees. If a fee is set so high that it bears no relation to your genuine loss and instead looks like a punishment for cancelling, a court may treat it as an unenforceable penalty rather than a valid pre-estimate of loss. A fee that reflects a realistic view of what a late cancellation actually costs you is far more likely to stand up.

Recovering Payment for Work Already Done

Where the dispute is really about an unpaid invoice for completed work, you have a well-trodden route. As a business supplying another business, you can rely on the Late Payment of Commercial Debts (Interest) Act 1998. This entitles you to statutory interest on overdue commercial invoices without needing a specific clause in your contract.

The statutory rate is 8% above the Bank of England base rate. For debts becoming late between 1 July and 31 December 2026, that works out at 11.75%. On top of the interest, the Act gives you automatic fixed compensation for the trouble of chasing the debt: £40 for debts under £1,000, £70 for debts between £1,000 and £9,999.99, and £100 for debts of £10,000 or more. You can read the government’s summary of your rights at GOV.UK’s guide to late commercial payments.

The steps to recover a debt

1. Send a clear reminder. A polite but firm statement of the amount due, the invoice date, and a payment deadline often prompts payment on its own.
2. Issue a Letter Before Action. If the reminder is ignored, send a formal letter setting out the debt, the interest and compensation claimed, and a deadline (commonly 14 to 30 days for a business), stating that court proceedings will follow if there is no adequate response. This is a required step under the pre-action rules and shows the court you acted reasonably.
3. Use Money Claim Online. For undisputed debts, you can start a claim through the government’s Money Claim Online service. Disputes up to £10,000 are usually dealt with on the small claims track, which is designed to be used without a solicitor.

Keep every email, quote, timesheet, and delivery note. In a small claims hearing, the contractor with a clear, dated paper trail almost always has the advantage.

How you treat a cancellation in your accounts depends on what the payment is for, and getting this wrong can create problems with HMRC.

Payment for work done or a notice period is normal trading income. It is subject to VAT if you are VAT registered, and it forms part of your taxable profit in the usual way. If you had already raised an invoice and accounted for the VAT, and the work then falls away, you may need to issue a credit note and adjust your VAT position. HMRC’s guidance on when supplies happen for VAT purposes is set out in its VAT time of supply notice.

Compensation and cancellation charges are trickier. HMRC’s position on the VAT treatment of termination and cancellation payments changed in recent years, and many such payments that were once treated as outside the scope of VAT are now treated as further consideration for the underlying supply, and therefore taxable. Because the treatment turns on the specific facts and the wording of your contract, this is an area where it pays to check rather than assume.

If you operate through a limited company, remember that any sum you recover belongs to the company, not to you personally. It is company income and follows the usual route of corporation tax on profits, with your own extraction of that money through salary or dividends taxed separately. For contractors inside IR35, the cancellation of an engagement does not by itself change your employment status determination for the work you did complete.

Practical Steps to Take Right Now

If a client has just cancelled on you, work through this checklist before firing off an angry email:

• Re-read the contract and identify the termination clause and any notice or cancellation terms.
• Establish whether the client has followed those terms or ignored them.
• Total up the work already completed and any expenses committed to the project.
• Note any other work you have turned down or can now pick up, to address the duty to mitigate.
• Gather your evidence: the contract, emails, quotes, timesheets, and delivery records.
• Communicate in writing, calmly and factually, setting out what you believe you are owed and why.
• Keep the tone professional. Many cancellations are resolved with a fair settlement, and you may want to work with this client, or their contacts, again.

How to Protect Yourself in Future

Most cancellation disputes are avoidable, or at least far less painful, when the contract deals with them properly from the outset. When agreeing your next engagement, make sure your terms include:

• A clear notice period for termination by either side.
• A cancellation charge that reflects your genuine loss if a client pulls out at short notice.
• Payment terms for completed and part-completed work.
• A deposit or upfront payment for larger projects, so you are not fully exposed if the work is cancelled midway.
• Confirmation of your right to charge statutory interest on late payments.

Simple, plain-English terms that both sides understand are worth far more than an elaborate contract nobody reads. If you use the same terms repeatedly, it is worth having them reviewed once so you can rely on them with confidence.

The Bottom Line on Contract Cancellations

When a client cancels, your rights come down to three things: what the contract permits, whether the client stayed within those terms, and what you can realistically show you have lost after making reasonable efforts to fill the gap. Payment for completed work and unserved notice is usually recoverable, and unpaid invoices carry statutory interest and compensation as of right. Keep good records, deal with the situation in writing, and treat the tax and VAT treatment of any settlement with care, because that is where avoidable mistakes are made.

The best protection, though, is the contract you sign before the work begins. Clear termination and cancellation terms turn a stressful dispute into a straightforward calculation.
