How to Draft a Consulting Agreement in the UK

If you need to know how to draft a consulting agreement in the UK, you are in the right place. A consulting agreement is a legally binding contract between a business and an independent consultant. It sets out the scope of work, payment terms, IP ownership, confidentiality obligations, and how either party can exit the arrangement. Getting this document right matters. Without a proper agreement, you risk disputes over deliverables, arguments about who owns the work product, and HMRC scrutiny over employment status. UK law does not require consulting agreements to follow a specific template, but several legal frameworks apply — including the Contracts Act, IR35 rules, and UK GDPR if personal data is involved. This guide walks you through every clause you need, what each one does, and where founders typically go wrong. Whether you are hiring a freelance consultant or formalising an ongoing advisory relationship, this page gives you a practical, UK-specific drafting checklist you can act on today.

Why this matters

Most founders reach for a generic template online, swap in a few names, and hope for the best. That approach creates real problems. A vague scope clause leads to scope creep and invoice disputes. Missing IP assignment language means the consultant could technically own the work they produced for you. No termination clause leaves you locked in with no clean exit. And if HMRC decides the arrangement looks like employment, the absence of a properly structured agreement makes your position much harder to defend. Writing a consulting agreement in the UK is not complicated, but it does require you to think through the relationship clearly before you sign anything.

The Atornee approach

Atornee is not a law firm and does not give legal advice. What it does is help UK founders generate a solid first draft of a consulting agreement in minutes, using prompts built around UK-specific legal requirements. You answer questions about the engagement — scope, fees, IP, termination — and Atornee produces a structured document you can review, edit, and take to a solicitor if the deal is complex enough to warrant it. For straightforward consulting arrangements, many founders find the draft is ready to use with minimal changes. For higher-stakes engagements, you go in with a document that is already 80 percent there, which cuts your legal bill significantly.

2
2. Decide whether the engagement is fixed-term or rolling, and set a clear start date and review point
3
3. Confirm the fee structure — day rate, project fee, or retainer — and specify payment terms and invoicing frequency
4
4. Include an IP assignment clause that transfers ownership of all work product to your business upon payment
5
5. Add a confidentiality clause or reference a separate NDA if sensitive business information will be shared
6
6. Check whether IR35 applies to this engagement and ensure the agreement reflects genuine self-employment indicators
7
7. Set out termination rights for both parties, including notice periods and what happens to work in progress on exit

FAQ

Does a consulting agreement need to be in writing in the UK?

No, UK law does not require a consulting agreement to be written to be enforceable. Verbal contracts can be legally binding. However, a written agreement is strongly advisable because it gives both parties a clear record of what was agreed, reduces the risk of disputes, and is essential if you ever need to enforce your rights or defend an HMRC inquiry.

What is the difference between a consulting agreement and an employment contract?

A consulting agreement covers an independent contractor relationship. The consultant is self-employed, invoices for their services, and is responsible for their own tax and National Insurance. An employment contract creates an employer-employee relationship with different legal obligations including holiday pay, sick pay, and PAYE. HMRC uses IR35 rules to assess whether a consulting arrangement is genuinely self-employed or disguised employment, so the wording and working practices both matter.

Who owns the intellectual property created during a consulting engagement?

By default under UK law, the consultant who creates the work owns the intellectual property unless the agreement says otherwise. This surprises many founders. If you want to own the deliverables — code, designs, reports, strategies — you must include an explicit IP assignment clause that transfers ownership to your business. Do not assume ownership transfers automatically just because you paid for the work.

Does a consulting agreement need to comply with UK GDPR?

If the consultant will access, process, or handle personal data on your behalf, yes. You will need a data processing agreement or appropriate data protection clauses within the consulting agreement itself. The ICO sets out the requirements for controller-processor relationships. Ignoring this creates regulatory exposure for your business, not just the consultant.

Can I use a US consulting agreement template for a UK engagement?

You can use it as a starting point, but you should not rely on it without significant revision. US templates reference US law, US tax concepts, and US employment classifications that do not map onto UK legal frameworks. Key areas that need UK-specific treatment include IR35, UK GDPR, the Contracts (Rights of Third Parties) Act 1999, and termination rights. A UK-specific template is always the safer starting point.

When should I involve a solicitor in drafting a consulting agreement?

For a straightforward short-term engagement with a clear scope and modest fees, a well-drafted template is usually sufficient. You should involve a solicitor when the engagement involves significant IP creation, access to sensitive data, a high contract value, exclusivity obligations, or any complexity around employment status. If you are unsure, a one-hour solicitor review of a solid draft is far cheaper than resolving a dispute later.
