Interim CMO Contract Template UK | Marketing Director Agreement
Bringing in an interim Chief Marketing Officer without a watertight contract exposes your business to scope creep, IP disputes, and costly IR35 misclassification. An interim CMO contract template establishes clear boundaries around deliverables, strategic authority, and the independent contractor relationship — all essential when a senior marketing leader is shaping brand direction on a fixed-term basis. Under Chapter 10 of ITEPA 2003, HMRC will scrutinise whether the engagement reflects genuine self-employment, making robust substitution and control clauses non-negotiable. The agreement should also protect against late payment under the Late Payment of Commercial Debts Act 1998, and assign ownership of all marketing assets and strategies created during the engagement. Whether you are a freelance marketing director or a business hiring one, generate your interim CMO contract now.

IR35 Status and Control
This clause defines the contractor's right of substitution, limits the client's day-to-day control over how work is performed, and confirms the absence of mutuality of obligation — the three key tests HMRC applies under Chapter 10 of ITEPA 2003. Without clear drafting here, an interim CMO embedded in a marketing team risks being deemed a disguised employee, triggering significant tax and National Insurance liabilities for the engaging business.
Intellectual Property Assignment
This clause explicitly transfers ownership of all marketing strategies, brand assets, campaign materials, and data insights created during the engagement from the contractor to the client upon full payment. Under the Copyright, Designs and Patents Act 1988, IP created by a self-employed contractor belongs to the contractor by default, so a written assignment is essential to ensure the business legally owns the work product.
Scope of Authority and Deliverables
This clause defines precisely what strategic and operational decisions the interim CMO is authorised to make, which budgets they can approve, and what measurable deliverables are expected within the agreed timeframe. Clear scope definition protects both parties — preventing the contractor from exceeding their mandate and protecting them from scope creep claims — and supports IR35 compliance by evidencing a project-based rather than employment-style engagement.

Does an interim CMO contract fall inside or outside IR35?
Whether an interim CMO engagement falls inside or outside IR35 depends on the specific working arrangements assessed against HMRC's status tests under Chapter 10 of ITEPA 2003, including substitution rights, control, and mutuality of obligation. For medium and large private sector clients, the responsibility for making the IR35 determination sits with the end client under off-payroll working rules introduced in April 2021. A well-drafted contract reflecting genuine self-employment practice significantly strengthens an outside-IR35 position, but the written terms must match the actual working relationship.
Can an interim CMO contract include a non-compete clause?
Yes, but any post-termination restrictive covenant in a UK contractor agreement must be reasonable in scope, duration, and geographic reach to be enforceable under common law. Courts apply a stricter test to contractor restrictions than to employment contracts, and an overly broad non-compete is likely to be struck down entirely rather than reduced. Typically, restrictions of three to six months targeting direct competitors or specific client poaching are more likely to be upheld than wide-ranging industry exclusions.
What payment terms should an interim CMO contract include?
Most interim CMO contracts operate on either a monthly retainer or milestone-based fee structure, with payment terms of 30 days being standard in the UK. Under the Late Payment of Commercial Debts Act 1998, if a business-to-business invoice is not paid on time, the contractor is entitled to claim statutory interest at 8% above the Bank of England base rate plus a fixed debt recovery charge. Including an explicit invoicing schedule and late payment interest clause in the contract makes enforcement straightforward and discourages delayed payment.
