Independent Contractor Agreement in the UK: Template and Key Clauses (2026)

An independent contractor agreement in the UK is the contract between a business (the client) and a self-employed person or their company (the contractor) who provides services without being an employee. The hardest part is not the drafting. It is making sure the real working relationship matches what the paper says, because in the UK a contract that calls someone self-employed does not settle the question. HMRC and employment tribunals look at how the work is actually done. This is general information, not legal advice. Employment status, tax and the enforceability of specific terms depend on your facts and can change, so confirm the current position before you rely on any clause. ## Why status is the first question The UK has three categories, not two. A person can be an employee, a worker, or genuinely self-employed. Employees get the full set of rights. Workers sit in the middle and still get holiday pay, the minimum wage and pension auto-enrolment. Only a genuinely self-employed contractor sits outside most of these rights. Tax status is a separate test again, run by HMRC. Courts and HMRC weigh a few things. Personal service: must the contractor do the work personally, or can they send a substitute? Control: who decides how, when and where the work is done? Mutuality of obligation: must the client offer work and the contractor accept it? The more the arrangement looks like an employee showing up to be told what to do, the weaker a self-employed label becomes. ## IR35 and the off-payroll working rules If the contractor works through their own company, often called a personal service company, the off-payroll working rules (known as IR35) may apply. Since April 2021, where the client is a medium or large business in the private sector, the client decides whether the engagement would be employment if the company were not there, and must issue a Status Determination Statement. If it would be employment, tax and National Insurance are deducted at source. Small clients and the public sector have their own positions. HMRC offers a tool called CEST (Check Employment Status for Tax) to help assess this. Getting IR35 wrong moves real tax liability, so name it in the contract and keep evidence of how status was decided. ## A clause by clause skeleton Use this as a structure to adapt, not a finished document. ``` INDEPENDENT CONTRACTOR AGREEMENT Parties: [Client name and registered address] and [Contractor name / company and address] Date: [date] 1. SERVICES The Contractor will provide the services set out in Schedule 1 (the Statement of Work). The Client does not control how the Contractor performs the services. 2. STATUS The Contractor is an independent contractor, not an employee or worker. The Contractor is responsible for their own income tax and National Insurance. Nothing creates a partnership or employment relationship. 3. SUBSTITUTION The Contractor may provide a suitably qualified substitute to perform the services, subject to the Client's reasonable approval. 4. OFF-PAYROLL WORKING (IR35) The parties' assessment of status for tax is recorded in Schedule 2. [Where the Client is a medium or large business, the Client will issue a Status Determination Statement.] 5. FEES AND PAYMENT The Client pays [amount] per [day / deliverable], invoiced [frequency], payable within [number] days. The Contractor bears their own expenses unless Schedule 1 says otherwise. 6. TERM AND TERMINATION This agreement runs from [date] until [date or completion]. Either party may end it on [number] days written notice, or immediately for material breach. 7. INTELLECTUAL PROPERTY All IP created in providing the services is assigned to the Client on creation. The Contractor waives moral rights so far as the law allows. 8. CONFIDENTIALITY AND DATA The Contractor keeps the Client's confidential information secret and complies with UK GDPR and the Data Protection Act 2018 for any personal data handled. 9. INSURANCE AND LIABILITY The Contractor maintains [professional indemnity / public liability] cover of [amount]. Liability is limited as set out in clause [x]. 10. GOVERNING LAW This agreement is governed by the law of [England and Wales / Scotland / Northern Ireland] and subject to the courts of that jurisdiction. Schedule 1: Statement of Work Schedule 2: Status assessment

- Ignoring IR35 when the contractor works through a company. The tax risk often sits with the client.
- Leaving out the IP assignment, so the client pays for work it does not own.
- Copying a US template with at-will termination and US tax wording that does not fit UK law.
- No data protection clause where the contractor will handle personal data. ## How jurisdiction within the UK changes things England and Wales, Scotland and Northern Ireland share employment law and tax largely, but courts, some procedures and contract interpretation differ, so name the right governing law. Rates, thresholds and the detail of the off-payroll rules change over time, so check the current HMRC guidance rather than relying on a figure in an old template. <!-- [VERIFY] current IR35 small-company thresholds and any rule changes for 2026 --> ## Keeping the agreement and its evidence together A contractor agreement is rarely one file. There is the signed contract, the status assessment, the schedules, the renewals and the invoices, and the proof of how status was decided if HMRC ever asks. When these live across email and shared drives, the one document you need is the one you cannot find. Drafting a contract like this, checking it for a clause that undercuts self-employed status, editing a term in plain language and keeping every version with its date can sit in one AI workspace tuned to how your company contracts. Adira is built on that idea, running on Claude, with per-seat pricing published up front and a 7-day trial, India-first and built to work across jurisdictions.

The point worth taking is that the contract and the evidence behind it are easier to defend when they stay in one place.
