Kill Fee Freelance Contract UK | Cancellation Compensation Clause Template
When a client cancels a project after work has begun, UK freelancers are often left with nothing to show for their time. A kill fee contract solves this by establishing a clear cancellation compensation clause that triggers payment when a client pulls the plug mid-project. Without this protection, recovering lost income depends on the general principles of contract law under the Contracts Act and common law breach of contract remedies, which can be slow and uncertain. A properly drafted kill fee clause specifies the percentage or fixed sum owed at each project stage, the notice period required, and how expenses are reimbursed. This protects both parties: the freelancer gets fair compensation, and the client gets predictable exit costs.

Key clauses in a Freelance Contract
Kill Fee Trigger Conditions
This clause defines exactly what constitutes a cancellation that activates the kill fee, including client-initiated termination, scope abandonment, or indefinite project suspension. Without precise trigger conditions, disputes arise over whether a project was genuinely cancelled or merely paused, leaving the freelancer without a clear legal basis for claiming payment.
Staged Compensation Schedule
This clause sets out the specific kill fee amount or percentage payable depending on how far the project has progressed at the point of cancellation. Tiered schedules — for example, 25% if cancelled before delivery, 50% if a draft has been submitted — reflect the actual work completed and align with UK common law principles that compensation should reflect genuine loss rather than operate as a penalty, which could otherwise be challenged under the penalty rule established in Cavendish Square Holding BV v Makdessi [2015] UKSC 67.
Invoice and Payment Terms
This clause specifies when the kill fee invoice must be issued after cancellation and the payment deadline the client must meet. Linking this to the Late Payment of Commercial Debts (Interest) Act 1998 allows the freelancer to charge statutory interest at 8% above the Bank of England base rate on any kill fee that is not paid on time, providing a meaningful financial deterrent against delayed settlement.

Is a kill fee clause legally enforceable in the UK?
Yes, provided the kill fee is a genuine pre-estimate of the freelancer's loss rather than a disproportionate punishment for cancellation. UK courts following the Supreme Court ruling in Cavendish Square Holding BV v Makdessi [2015] will uphold cancellation clauses that reflect legitimate business interests. A staged kill fee tied to work completed is far more likely to be enforced than a flat penalty with no connection to actual loss.
Does accepting a kill fee affect my IR35 status?
A kill fee clause can actually support outside-IR35 status because it demonstrates financial risk on the freelancer's part, which is one of the indicators HMRC considers under the Chapter 10 ITEPA 2003 rules. Employees do not typically bear the financial risk of a project being cancelled, so this clause reinforces genuine self-employment. It is worth including it alongside other contractual indicators such as substitution rights and control provisions.
What percentage should a kill fee be in a UK freelance contract?
There is no fixed legal standard, but common practice in UK freelance markets runs from 25% to 100% depending on the project stage, with 50% being a widely used midpoint for cancellations after work has begun. The figure should reflect your actual costs and time invested at each stage to withstand scrutiny if challenged. Many freelancers also add a clause requiring reimbursement of any out-of-pocket expenses incurred before cancellation, regardless of the kill fee percentage.
