Freelance contract template UK: what to include (and what most templates miss)

1. The essential clauses every UK freelance contract needs

These are the minimum provisions for any client-facing freelance agreement in the UK:

• Parties. Full legal names — not trading names. If you operate through a limited company, use the registered company name and number, not your personal name.
• Scope of work.Deliverables, not a job title. “Design and deliver five responsive page layouts to approved wireframes by 30 June” is enforceable. “Web design work” is not.
• Rate and payment terms. Day rate or fixed project fee, invoicing frequency, payment deadline (industry standard: 30 days net), and Late Payment Act interest provisions.
• Intellectual property. Who owns what you create — and when ownership transfers. Under UK law, the default is that you own it until you assign it in writing.
• Confidentiality. What information is confidential, for how long, and what is excluded (information that becomes publicly known, prior knowledge).
• Termination. Notice period, kill fee for work completed before termination, and obligations regarding delivery of work in progress.
• Governing law.England & Wales, Scottish law, or Northern Ireland. This determines which court handles disputes and which rules apply to interpretation.

Most free freelance contract templates include the first three. The last four — IP, confidentiality, termination, and governing law — are where disputes happen and where generic templates most often fall short.

2. IR35 — what your contract must say

IR35 is the legislation HMRC uses to determine whether a contractor is genuinely self-employed or is, in substance, an employee for tax purposes. For engagements with medium and large private-sector clients, the Off-Payroll Working rules (Chapter 10 ITEPA 2003) mean the client assesses IR35 status — and that assessment starts with the contract.

A freelance contract template that ignores IR35 exposes both parties: the contractor risks a tax bill, and the client risks an unexpected employer PAYE liability. Three clauses determine IR35 outcome more than any others:

All three clauses must appear explicitly — not as implied terms. A contract that says the opposite of how the engagement actually works is worse than no contract at all.

Contracto’s freelance contract generator includes all three IR35 clauses as standard, drafted in line with Ready Mixed Concrete [1968] and current HMRC CEST guidance.

3. Late Payment Act provisions

The Late Payment of Commercial Debts (Interest) Act 1998, as amended in 2013, gives every UK business the right to charge statutory interest on overdue B2B invoices. The rate is 8% above the Bank of England base rate. At the current base rate of 4.25% (May 2026), that is 12.25% per annum.

The Act applies automatically to commercial transactions. You do not need to reference it in your contract. But including an explicit Late Payment clause achieves two things:

• It puts clients on notice before the project starts that late payment has a specific, calculable cost — creating a commercial incentive to pay on time.
• It removes any ambiguity about your intention to enforce it, which matters if the matter goes to a small claims or county court.

A clean payment clause reads: “Payment is due within 30 days of invoice. Overdue amounts accrue interest at 8% above the Bank of England base rate under the Late Payment of Commercial Debts (Interest) Act 1998, together with the statutory compensation fee applicable to the invoice value.”

4. Intellectual property ownership

Under the Copyright, Designs and Patents Act 1988, the creator of a work owns the copyright by default — not the commissioner. This is the opposite of what most clients assume, and it is the most common source of post-project disputes.

Your freelance contract template must address IP explicitly. The two standard arrangements:

• Full assignment on payment. The freelancer assigns all IP rights in the deliverables to the client upon receipt of full payment. Standard for most client-commissioned creative and technical work. The assignment takes effect only on payment — giving the freelancer a form of security.
• Licence only. The freelancer retains ownership and grants the client a licence to use the work — exclusive or non-exclusive, perpetual or time-limited. Used when the freelancer produces modular work (code libraries, design systems) they intend to reuse across clients.

The IP clause should specify: what is assigned (final deliverables only, or also working files and source code), when it transfers (on payment in full — not on delivery), and whether background IP — pre-existing tools, frameworks, code — is excluded from the assignment.

Note: moral rights under s.77 CDPA 1988 (the right to be identified as author) cannot be assigned but can be waived. For commercial client work, waiver is standard.

5. Termination and kill fee clauses

A freelance contract without an explicit termination clause defaults to “reasonable notice” under common law. What is reasonable is determined by a court after the fact — not by you in advance.

A well-drafted termination clause specifies three things:

• Notice period. Typically 14 to 30 days for project-based engagements; 30 to 90 days for ongoing retainers.
• Kill fee (Cancellation Compensation). If the client terminates early, they pay for work completed to the termination date plus a cancellation compensation fee — typically 25 to 50% of the remaining contract value. Following Cavendish Square Holding BV v El Makdessi[2015] UKSC 67, this clause is enforceable in England and Wales where the amount is a genuine pre-estimate of loss, not a penalty designed to punish. The label matters: “Cancellation Compensation (Liquidated Damages)” is more defensible than “kill fee” or “penalty.”
• Work in progress. On termination, the freelancer delivers all work completed to date; the client pays for it at the agreed rate.

6. Governing law — why it matters which UK jurisdiction you choose

England and Wales, Scotland, and Northern Ireland are three separate legal systems. The differences that affect freelance contracts most:

• Consideration. English contract law requires consideration (something of value exchanged) to form a binding contract. Scottish law does not — an offer and acceptance are sufficient. For most freelance contracts this makes little practical difference, but it affects whether a contract variation without additional payment is enforceable.
• Liquidated damages. Scottish courts apply the penalty rulemore strictly than English courts since Cavendish Square. A kill fee that is enforceable in England may face more scrutiny in Scotland.
• Implied terms. The Contract (Scotland) Act 1997 affects which terms are implied into commercial contracts under Scottish law.

Your contract should include: “This agreement is governed by and construed in accordance with the laws of [England and Wales / Scotland / Northern Ireland], and the parties submit to the exclusive jurisdiction of the courts of [England and Wales / Scotland / Northern Ireland].”

If your client is in a different UK jurisdiction, agree on one upfront rather than leaving it to be determined by a court.

7. Free template vs. generated contract: the real difference

A free freelance contract template downloaded from the internet is a starting point. The practical risks:

• Out of date. Employment Rights Act 2024 introduced changes to worker status provisions. Most free templates predate it and have not been updated.
• Wrong engagement type. A day-rate contractor template is materially different from a fixed-price project template, which is different again from a retainer agreement. Generic templates try to cover all three and often cover none of them well.
• No IR35 clauses. IR35 provisions are frequently absent or drafted without reference to CEST guidance or case law.
• Wrong jurisdiction. Most free templates default to England and Wales without confirming it applies to your situation.
• No Late Payment Act clause. The Act applies automatically, but the absence of an explicit clause signals to clients that you may not enforce it.

A generated contract — built from your specific engagement details, jurisdiction, rate, deliverables, and payment terms — starts from a legally maintained base and populates the variable clauses correctly for your situation. The underlying template is updated when legislation changes; the output is specific to your engagement.
