Kill Fee Clause Template UK — Cancellation Compensation for Freelancers

The client emails on a Wednesday: "We have decided to pause the project indefinitely. Thanks for your work so far."

You have blocked two weeks of your calendar. You turned down another lead. You have delivered wireframes and the first design round. But the project was invoiced on completion — and now there is no completion.

You know you are owed something. But your contract does not say what happens when a client cancels mid-project.

This is where a kill fee clause protects you.

A kill fee (also called cancellation compensation) is the amount a client pays when they cancel a project before completion. It compensates you for the opportunity cost — the income you could have earned if you had not blocked your calendar for their work.

This guide gives you a pasteable UK kill fee contract clause with a worked GBP stage table (0% to 100%) for designers and developers, a cancellation notice email template, kill fee invoice line items, a decision test for when you need a kill fee vs when a deposit and staged invoicing are enough, and answers to the most common questions UK freelancers have about charging kill fees.

What a kill fee is (and why freelancers confuse it with deposits)

A kill fee is compensation you receive when a client cancels a project mid-way through.

It is not the same as a deposit or an invoice for work already done.

Kill fee vs deposit vs work-done invoice

Kill fee:

✓ Applies when the client cancels mid-project
✓ Percentage of total project fee, increasing as project progresses
✓ Covers lost opportunity cost (you blocked your calendar, turned down other work)
✓ Must be written into your contract before the project starts

Deposit:

✓ Paid upfront before work starts
✓ Usually 25–50% of total project fee
✓ Protects you if the client cancels very early (filters non-serious clients)
✓ If project completes, deposit is deducted from final invoice

Work-done invoice:

✓ Invoice for deliverables already completed
✓ Based on time spent or milestones delivered
✓ No contract clause needed — you invoice for what you delivered

Example:

• You agree a £4,000 website project with a 30% deposit (£1,200) and completion invoice (£2,800)
• Client pays deposit, you start work
• Two weeks in, client cancels (wireframes done, design 50% complete)
• Without a kill fee clause: You keep the deposit and invoice for any additional work done (maybe £400 for extra hours) = £1,600 total
• With a kill fee clause (50% at this stage): You keep the deposit and invoice the kill fee (£4,000 × 50% = £2,000, minus £1,200 deposit already paid = £800) = £2,000 total

The kill fee compensates you for the cancelled project as a whole, not just the hours you spent.

Why UK freelancers do not always use kill fees

Many freelancers rely on deposits and staged invoicing instead:

✓ Invoice 30% upfront, 30% at first milestone, 40% on completion
✓ If the client cancels mid-project, you have already invoiced and been paid for most of the work

This works well for short projects (1–2 weeks) or small budgets (under £1,000).

Kill fees are more useful for longer projects (3+ weeks), larger budgets (£2,000+), or high-risk clients (new clients, agencies, industries with high cancellation rates like startups or marketing agencies).

Tip: Use both. A deposit protects you at the start. Staged invoices keep cashflow healthy. A kill fee clause protects you if they cancel mid-project before the next invoice is due.

Pasteable kill fee contract clause — cancellation compensation with stage table

Add this clause to the Payment Terms or Termination section of your freelance contract.

This clause gives the client the right to cancel at any time, but requires them to pay cancellation compensation based on how far the project has progressed.

Cancellation Compensation (Kill Fee)

Either party may terminate this contract at any time by providing written notice to the other party.

If the Client cancels this project before completion, the Client agrees to pay cancellation compensation as follows:

"Project kickoff" means the date the Freelancer begins work as agreed in the project timeline.

"Deliverable" means a milestone or deliverable as defined in the Scope of Work (Appendix A).

Cancellation compensation is due within 14 days of the cancellation notice. Any deposit or milestone payments already made will be deducted from the cancellation compensation owed.

If the Freelancer cancels the project, the Client is not required to pay cancellation compensation. Any deposit paid will be refunded, minus any costs incurred for work already completed.

How the clause works

Scenario 1 — Client cancels before you start:

• Total project fee: £3,000
• Client emails before the agreed start date: "We have decided to cancel."
• Cancellation compensation: 0% = £0
• Client pays nothing (or you refund the deposit if already paid)

Scenario 2 — Client cancels after kickoff but before first deliverable:

• Total project fee: £3,000
• Client paid 30% deposit (£900)
• You have started work (discovery call, wireframes in progress)
• Client cancels
• Cancellation compensation: 25% of £3,000 = £750
• Client already paid £900 deposit, which is more than £750, so no additional payment due
• You keep £750 of the deposit, refund £150

Scenario 3 — Client cancels after first deliverable (design round 1):

• Total project fee: £3,000
• Client paid 30% deposit (£900)
• You delivered wireframes and first design round
• Client cancels
• Cancellation compensation: 50% of £3,000 = £1,500
• Client already paid £900, so they owe £1,500 - £900 = £600
• You invoice £600 as kill fee

Scenario 4 — Client cancels near completion:

• Total project fee: £3,000
• Client paid deposit (£900) and first milestone invoice (£900) = £1,800 paid
• You delivered most of the project, final QA and handoff pending
• Client cancels
• Cancellation compensation: 75% of £3,000 = £2,250
• Client already paid £1,800, so they owe £2,250 - £1,800 = £450
• You invoice £450 as kill fee

Scenario 5 — Client cancels after final delivery:

• Total project fee: £3,000
• You delivered everything
• Client cancels (e.g. they decide not to use it)
• Cancellation compensation: 100% = £3,000
• Client owes the full project fee (minus any payments already made)

Why the 100% stage matters: Some clients try to cancel after you deliver, claiming they "changed their mind." The 100% clause prevents this. Once you deliver the final work, they owe you the full fee whether they use it or not.

GBP stage table examples — designer and developer scenarios

Here are two realistic kill fee scales for UK freelancers.

Example 1 — Brand identity designer (£2,400 project, 4 weeks)

30% deposit: Client pays £720 upfront. If they cancel in Week 2 (after logo concepts), they owe £1,200 total. They already paid £720, so you invoice £480 as kill fee.

Example 2 — Web developer (£5,000 project, 6 weeks)

25% deposit: Client pays £1,250 upfront. If they cancel after frontend build (week 3), they owe £2,500 total. They already paid £1,250, so you invoice £1,250 as kill fee.

How to adjust the percentages

More granular stages (e.g. 0%, 10%, 25%, 40%, 60%, 80%, 100%) work well for long projects (8+ weeks) or projects with many milestones.

Simpler stages (e.g. 0%, 50%, 100%) work well for short projects (1–2 weeks) or projects with only one or two clear deliverables.

Higher early percentages (e.g. 40% after kickoff) work well if you have high upfront research or discovery time (brand strategy, UX research).

Industry norms:

• Journalism/editorial: Often 25–50% kill fee (because editors cancel after commissioning but before publication)
• Photography: Often 50–100% (because photographers block a specific date)
• Design/development: Often staged as above (25% → 50% → 75% → 100%)

Tip: The earlier the client cancels, the less you have delivered — but the more opportunity cost you have incurred (you turned down other work, blocked your calendar). A 25% kill fee after kickoff compensates you for that lost opportunity even if you only spent a few hours.

Pasteable cancellation notice email — what to send when a client cancels

When a client cancels, reply immediately to confirm receipt and state the cancellation compensation due.

Worked example — cancellation notice with real numbers

Subject: Re: Project cancellation — cancellation compensation due

Hi Sophie,

Thank you for letting me know. I confirm that the Northline Studio website redesign project is cancelled as of 14 September 2026.

Under the terms of our contract (section 6 — Cancellation Compensation), cancellation compensation is due based on the project stage at the time of cancellation.

Project stage at cancellation: After first deliverable submitted (wireframes and homepage design, round 1)
Cancellation compensation: 50% of total project fee (£3,500) = £1,750

Payments made to date:

• Deposit: £1,050 (paid 28 August 2026)
• Total paid: £1,050

Balance due: £700 (£1,750 - £1,050)

I will send a formal invoice for £700 today. Payment is due within 14 days as per our contract terms.

If you have any questions about this calculation, please let me know.

Best regards,
Alex Carter

When to send this email:

✓ The client has sent written notice that they are cancelling (email or message)
✓ You have a signed contract with a kill fee clause
✓ You want to confirm the cancellation and state the amount due immediately

Why send it immediately:

If you wait days to invoice, the client may assume they owe nothing. Confirm the cancellation and the kill fee amount within 24 hours.

Pasteable kill fee invoice line items — how to invoice cancellation compensation

Invoice the kill fee as a normal invoice. State the reason clearly so the client (and their accounts team) understands what they are paying for.

Kill fee invoice template (line items and wording)

Invoice line items:

Or simpler:

Invoice footer note:

This invoice is for cancellation compensation as agreed in our contract dated [Contract Date], section [X]. The project was cancelled on [Date] at the [Stage Name] stage. Payment terms: Net 14.

Worked example — kill fee invoice with GBP amounts

Invoice INV-2026-089
Date: 14 September 2026
Due date: 28 September 2026 (Net 14)

Bill to:
Northline Studio Ltd
[Address]

From:
Alex Carter
[Address]

Payment terms: Net 14. Payment is due by 28 September 2026.

Late payment: Overdue invoices will incur statutory interest and recovery costs as permitted by law.

Why the wording matters:

Stating the contract clause and project stage makes it clear this is not a surprise charge. The client agreed to this when they signed the contract. If they query it, you refer them to the signed contract.

Tip: Attach a copy of the signed contract (or the relevant page showing the kill fee clause) to the invoice email.

What if the client refuses to pay the kill fee?

Kill fees are contractual debts. If the client signed a contract with a kill fee clause and then cancels, they owe the money.

If they refuse to pay, chase it like any unpaid invoice:

Step 1 — Polite reminder (7 days after due date)

Hi [Name],
Invoice [Invoice Number] for £[Amount] was due on [Due Date] and remains unpaid. This invoice is for cancellation compensation as agreed in our contract (section [X]).
Please confirm payment by [Deadline].
Best regards, [Your Name]

Step 2 — Statutory interest demand (14–21 days overdue)

If they ignore the first reminder, send a formal interest demand stating you will charge statutory interest under the Late Payment of Commercial Debts Act 1998.

Read our statutory interest guide for a full interest demand email template and GBP calculation examples.

Step 3 — Letter before action (21–28 days overdue)

If they still do not pay, send a formal letter before action. This warns them you will take them to small claims court if they do not pay within 7–14 days.

Read our letter before action template guide for copy-paste templates with interest and recovery cost breakdowns.

Step 4 — Small claims court

If the deadline passes and they still have not paid, file a claim via Money Claim Online.

Most clients pay when they see a letter before action. Nobody wants a county court judgment on their credit record.

Tip: If the client is a limited company, check Companies House before you file. If they have gone into liquidation, you will not recover the debt even if you win.

Decision test — when you need a kill fee vs when deposit + staged invoices are enough

Not every project needs a kill fee clause. Use this decision tree.

Use a kill fee clause if:

✓ Project budget is £1,500+ (enough money at risk to justify the clause)
✓ Project timeline is 3+ weeks (longer projects = higher cancellation risk)
✓ You are blocking significant calendar time (e.g. turning down other leads, booking out your next two weeks)
✓ Client is new or unknown (no track record, first time working together)
✓ Client is in a high-cancellation industry (startups, agencies, marketing, event-based work)
✓ You have been burned before by mid-project cancellations

Skip the kill fee clause if:

✓ Project budget is under £500 (not worth the admin)
✓ Project timeline is under 1 week (low cancellation risk, you can absorb it)
✓ You invoice in short stages (e.g. 30% upfront, 30% at day 3, 40% at day 7 — you are paid before they can cancel)
✓ Client is a repeat client with a solid payment history
✓ You prefer simple contracts and are comfortable with the risk

Alternative approach — deposit + tight staged invoicing:

Instead of a kill fee clause, invoice frequently:

• £2,000 project: Invoice £600 upfront, £700 at day 5, £700 at day 10
• If client cancels at day 6, you have already invoiced and been paid £1,300 (65%)
• No kill fee clause needed — you protect yourself with frequent invoicing

This works well for short projects or hourly/day-rate work.

Kill fees work better for milestone-based projects where you deliver in chunks (e.g. designs every 2 weeks) and invoicing is less frequent.

Tip: Use both. A deposit protects you early. Staged invoices keep cashflow healthy. A kill fee clause catches edge cases where the client cancels between invoices.

Common mistakes that weaken your kill fee clause

Calling it a "penalty." Do not write "cancellation penalty" in your contract. Courts do not enforce penalty clauses. Call it "cancellation compensation" or a "kill fee" — compensation for an express right to cancel, not a punishment.

Not defining "deliverable" or "stage." If your contract says "50% kill fee after first deliverable" but does not define what a deliverable is, the client can argue nothing was delivered yet. Define stages clearly in your Scope of Work.

Charging 100% upfront as a "kill fee." A kill fee is compensation when a client cancels, not a non-refundable deposit. If you charge 100% upfront and call it a kill fee, clients will not sign. Use a deposit + kill fee scale instead.

Adding a kill fee clause after the project starts. Kill fees must be agreed before work starts. You cannot email mid-project and say "By the way, if you cancel now you owe me 50%." It must be in the signed contract.

Using a kill fee clause for hourly work. Kill fees are for fixed-price projects. If you work hourly, you invoice for hours worked — no kill fee needed. The client is already paying for your time.

Not adjusting the scale for project length. A 2-week project and an 8-week project need different kill fee scales. Longer projects should have more granular stages (e.g. 0%, 15%, 30%, 50%, 70%, 85%, 100%).

Ignoring deposits in the kill fee calculation. If the client paid a £1,000 deposit and the kill fee is £1,200, they owe you £200, not £1,200. Always deduct payments already made.

What if the client wants to cancel because the work is not good enough?

This is a grey area.

If the client cancels because you failed to meet the agreed standard (you delivered poor work, missed deadlines, ignored the brief), the kill fee may not apply. Courts could rule the clause is unfair because you breached the contract first.

If the client cancels because they changed their mind, ran out of budget, or decided they do not need the project anymore — and your work met the agreed standard — the kill fee applies.

How to frame your clause to handle this:

Add this sentence to your kill fee clause:

Cancellation compensation applies when the Client cancels the project by choice. It does not apply if the Client cancels due to the Freelancer's failure to meet the agreed deliverable standards as defined in the Scope of Work.

This protects the client from paying a kill fee if you deliver unusable work. It protects you if they cancel for reasons unrelated to your work quality.

Tip: Document everything. If a client cancels and claims your work was poor, you need proof that your deliverables met the brief. Save all emails, design files, feedback, and approvals. If they approved the work, they cannot later claim it was not good enough.

Can I charge a kill fee if the contract does not mention it?

No.

Unlike statutory interest (which applies automatically under UK law), kill fees are contractual. If your contract does not mention cancellation compensation, you cannot invoice it.

If a client cancels and your contract is silent on cancellation, you can only invoice for work already completed.

What to do if a client cancels and you have no kill fee clause:

✓ Invoice for time spent or deliverables completed (e.g. £600 for 12 hours at £50/hour, or £400 for wireframes delivered)
✓ Keep any deposit already paid (if your contract says deposits are non-refundable)
✓ Write off the opportunity cost and move on
