Effective date: enter start date above
1. Agreement Parties
Contractor: Contractor name, Contractor address. Email: [email protected].
Client: Client name, Client address. Email: [email protected].
2. Services & Deliverables
The Contractor agrees to provide services for: project title, commencing start date and concluding end date / until terminated. Services and deliverables are as set out in the project brief or statement of work agreed in writing by both parties. Any material change to scope requires a written variation signed by both parties.
3. Independent Contractor Status (IR35)
The Contractor is an independent contractor — not an employee, worker, or agent of the Client. The following employment status indicators are documented in this Agreement:
Control: The Contractor determines the method, manner, and means of performing the Services. The Client specifies what is required and by when but does not direct how work is performed.
Mutuality of Obligation: The Client is not obliged to offer further work beyond this Agreement; the Contractor is not obliged to accept further engagements. There is no ongoing expectation of work between the parties.
Substitution: The Contractor retains a genuine, unfettered right to provide a suitably qualified substitute to perform the Services. This right is not subject to Client approval except on reasonable grounds of suitability.
The Contractor is responsible for their own income tax, National Insurance Contributions (NICs), and VAT. The Client shall not deduct PAYE unless required to do so by a Status Determination Statement (SDS) under the off-payroll working rules (ITEPA 2003, Part 2 Chapters 8 and 10). From 6 April 2026, the small company exemption applies to clients with turnover ≤ £15M, balance sheet ≤ £7.5M, and ≤ 50 employees — for such clients, IR35 determination is the Contractor's responsibility.
4. Fees, Payment & Invoicing
Fee: GBP (£) amount (Fixed project fee).
Payment terms: 30 days from invoice date. The Contractor will submit invoices at agreed intervals or on completion of deliverables. The Client shall pay each invoice by the due date. Time of payment is of the essence.
If the Contractor is VAT-registered (threshold: £90,000 per rolling 12-month period, HMRC 2026/27), VAT at the prevailing rate (currently 20%) will be added to all invoices. The Contractor shall display their VAT registration number on all invoices.
5. Late Payment (Late Payment of Commercial Debts (Interest) Act 1998)
Invoices unpaid after the due date carry statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998 at 8% per annum above the Bank of England base rate on the overdue sum, together with the applicable fixed debt recovery charge (£40 for debts under £1,000; £70 for £1,000–£9,999; £100 for £10,000 or more). The Contractor reserves the right to suspend delivery of all Services and deliverables until all outstanding sums are paid in full. The UK Government's March 2026 late payment reforms (60-day cap, mandatory interest clause) are expected to strengthen these rights further from 2027.
6. Intellectual Property Assignment (CDPA 1988)
By operation of s.11 of the Copyright, Designs and Patents Act 1988, all intellectual property in deliverables created by the Contractor vests in the Contractor upon creation. Copyright is not transferred by payment of fees alone.
Upon receipt of all fees due under this Agreement, the Contractor assigns to the Client with full title guarantee all right, title, and interest (including copyright, design rights, and database rights) in all deliverables specifically created for the Client, by way of present and future assignment under CDPA 1988 s.90. This assignment is in writing and signed by the Contractor as part of this Agreement.
The Contractor waives all moral rights in the deliverables to the extent permitted by CDPA 1988 ss.80–89.
Background IP: The Contractor retains all pre-existing IP, tools, methodologies, and know-how ("Background IP"). The Client receives a royalty-free, perpetual, non-exclusive licence to use Background IP solely as embedded in or required to use the deliverables. No Background IP transfers to the Client.
7. Confidentiality & Data Protection
The Contractor shall keep all Client Confidential Information strictly confidential during and for 2 years after termination of this Agreement. Confidential Information means all non-public business, technical, financial, and commercial information disclosed by the Client. Exceptions: information already in the public domain (not through the Contractor's breach), required by law or court order, or independently developed by the Contractor without use of the Client's information.
To the extent the Contractor processes personal data on behalf of the Client, the Contractor acts as a data processor under Article 28 UK GDPR and shall: (i) process personal data only on the Client's documented instructions; (ii) implement appropriate technical and organisational security measures; (iii) not transfer personal data outside the UK without appropriate safeguards (UK IDTA or equivalent); (iv) comply with the Data (Use and Access) Act 2025 and current ICO guidance.
8. Expenses & Equipment
The Contractor supplies their own equipment, software licences, and workspace at their own cost. The Contractor is responsible for maintaining their own professional indemnity and public liability insurance in amounts appropriate for the engagement. Only expenses expressly pre-approved in writing by the Client are reimbursable; the Contractor shall provide receipts for all claimed expenses.
9. Termination
For convenience: Either party may terminate this Agreement on 30 days written notice.
For cause: Either party may terminate immediately on written notice if the other materially breaches this Agreement and fails to remedy that breach within 14 days of written notice specifying the breach.
Insolvency: Either party may terminate immediately if the other becomes insolvent, makes a voluntary arrangement with creditors, or enters administration or liquidation.
On termination: the Client shall pay for all work satisfactorily completed to the termination date; the Contractor shall promptly deliver all work product, Client materials, and data. Clauses 6 (IP), 7 (Confidentiality), and 10 (Liability) survive termination.
10. Warranties, Limitation of Liability & Governing Law
The Contractor warrants that all deliverables are original, do not infringe any third-party IP rights, and the Contractor has full right and authority to assign them. The Contractor indemnifies the Client against third-party IP claims arising from breach of this warranty. The Client warrants that all Client-supplied materials are owned or properly licensed, and the Client has authority to enter this Agreement.
Liability cap: Each party's aggregate liability is limited to the total fees paid or payable under this Agreement in the 12 months preceding the claim. Neither party is liable for indirect, consequential, or special loss, loss of profit, or loss of data. Nothing in this clause limits liability for death, personal injury caused by negligence, or fraud.
Governing law: England and Wales. The courts of England and Wales shall have exclusive jurisdiction. Any dispute shall first be referred to 30 days of good-faith negotiation, then mediation (CEDR or equivalent), before formal proceedings.
This Agreement is the entire agreement between the parties and supersedes all prior representations. Amendments are valid only if in writing and signed by both parties. If any provision is held invalid or unenforceable, the remainder continues in full force.

Frequently Asked Questions
An employee works under a contract of employment, receives PAYE deductions and NIC contributions, and holds statutory employment rights (unfair dismissal, holiday pay, sick pay). An independent contractor is self-employed, invoices for services, and handles their own tax and NICs. UK courts apply three tests: control (who decides how work is performed), mutuality of obligation (whether ongoing work must be offered and accepted), and substitution (whether the individual can send a qualified replacement). A contractual label alone does not determine status — the real working relationship governs. The Employment Rights Act 2025 (Royal Assent 18 December 2025) does not directly affect genuine independent contractors outside IR35.
A well-drafted contract is necessary but not sufficient for IR35. HMRC can look beyond the contract to the actual working practices. From 6 April 2026, the small company exemption threshold increased significantly — a client with turnover ≤ £15M (up from £10.2M), balance sheet ≤ £7.5M (up from £5.1M), and ≤ 50 employees is now exempt. Around 14,000 companies were reclassified as small, with IR35 determination reverting to the contractor's Personal Service Company (PSC). For medium and large clients, the client must issue a Status Determination Statement (SDS). This template documents all three employment status indicators (control, MOO, substitution) to support an outside-IR35 position.
Under the Copyright, Designs and Patents Act 1988 (s.11), the contractor is the automatic first owner of all IP they create — the opposite of the default for employees (where the employer owns work created in the course of employment). To transfer ownership to the client, the agreement must include an explicit written IP assignment signed by the contractor (CDPA s.90). Without this clause, the client receives only a licence to use the work, not ownership of the copyright or other IP rights. This template includes a full IP assignment clause plus a Background IP carve-out that protects the contractor's pre-existing tools and methodologies.
Yes. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge statutory interest of 8% above the Bank of England base rate on overdue B2B invoices — approximately 12.5% per annum as of mid-2026. You can also claim fixed debt recovery compensation: £40 for debts under £1,000, £70 for £1,000–£9,999, and £100 for £10,000 or more. You can also suspend work until the debt is paid. The UK Government's March 2026 late payment reforms will introduce a 60-day payment cap for large-to-small business payments, further strengthening these rights from 2027.
Yes. A written independent contractor agreement is legally binding under English, Scots, and Northern Irish law once both parties have agreed to its terms (offer, acceptance, and consideration). A written agreement is strongly recommended because it provides clear, enforceable evidence of scope, fee, IP ownership, IR35 indicators, and termination rights. Courts will enforce the agreed terms provided they are not unlawful or contrary to public policy. Verbal contracts are also binding but are much harder to enforce when a dispute arises.
Yes. A genuine self-employed contractor must register with HMRC for Self Assessment and file annual tax returns. VAT registration is required if taxable turnover exceeds the £90,000 threshold in a rolling 12-month period (2026/27, unchanged since April 2024). Contractors operating through a limited company (PSC) must also register at Companies House, pay corporation tax, and comply with PAYE and dividend obligations. HMRC's Check Employment Status for Tax (CEST) tool can help assess IR35 status, though its output is advisory and not legally binding on HMRC.
