Freelance Web Developer Contract Template UK
Without a clear written agreement, UK freelance web developers risk disputes over project scope, payment timelines, and intellectual property ownership — leaving both parties exposed to costly legal conflicts. A robust freelance web developer contract establishes exactly who owns the finished code, when invoices must be paid, and how the working relationship is structured to remain compliant with IR35 legislation under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003. It also protects your right to statutory interest on overdue invoices under the Late Payment of Commercial Debts Act 1998. Whether you are a developer securing your next project or a business commissioning a bespoke website, a properly drafted contract is essential. Generate a tailored UK freelance web developer contract now and protect your position from day one.

Intellectual Property Assignment
This clause defines who owns the source code, design assets, and any other deliverables once the project is complete and payment has been received in full. Under UK copyright law governed by the Copyright, Designs and Patents Act 1988, copyright in original works created by a freelancer belongs to them by default, making an explicit written assignment critical for the client to obtain full legal ownership.
Project Scope and Deliverables
This clause sets out precisely what the developer is contracted to build, including specific features, technologies, platforms, and acceptance criteria, preventing scope creep that can erode profitability. A tightly defined scope also supports IR35 compliance by demonstrating that the engagement relates to a specific output rather than an ongoing employee-like role, as assessed under Chapter 10 of ITEPA 2003.
Payment Terms and Late Fees
This clause specifies the agreed fee, payment milestones, invoice due dates, and the statutory interest rate that applies to overdue amounts. Under the Late Payment of Commercial Debts Act 1998, freelancers are entitled to charge 8% above the Bank of England base rate on late B2B payments, along with fixed debt recovery costs, and this clause ensures those rights are clearly communicated and contractually acknowledged.

Does my freelance web developer contract need to address IR35?
Yes, your contract should include clauses that reflect a genuine business-to-business relationship, such as a substitution right, control over how work is delivered, and a defined project output. HMRC assesses IR35 status under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003 by looking at the practical reality of the engagement, but a well-drafted contract that accurately reflects working practices is an important starting point. Since April 2021, medium and large private sector clients are responsible for determining IR35 status, so both parties benefit from contractual clarity.
Who owns the website code if there is no contract in place?
Without a written agreement, copyright in original code and design assets created by a freelance developer automatically belongs to the developer under the Copyright, Designs and Patents Act 1988, not the client who commissioned the work. This means a business could pay in full for a website yet have no legal right to modify or redistribute the underlying code without the developer's permission. A signed contract with an explicit intellectual property assignment clause is the only way to transfer ownership securely.
Can a freelance web developer charge interest if a client pays late?
Yes, freelance web developers working on a business-to-business basis are legally entitled to claim statutory interest at 8% above the Bank of England base rate on overdue invoices under the Late Payment of Commercial Debts Act 1998. They can also claim fixed debt recovery costs ranging from £40 to £100 depending on the invoice value, without needing to go to court first. Including a payment terms clause in your contract that explicitly references these statutory rights reinforces your position and encourages prompt payment.
