Advisory Agreement for UK Consultants

If you're a UK consultant being brought on as a startup advisor, you need a proper consultant startup advisor agreement uk before you do a single hour of work. This document sets out what you're actually agreeing to: your scope of advice, how often you show up, what equity or fees you're getting, and critically, what you own versus what the startup owns. Without it, you're exposed. Startups often assume advisors are working for free or that IP created during advisory sessions belongs to the company by default. Neither is automatically true under UK law, but ambiguity costs you. A well-drafted advisory agreement protects your time, your intellectual property, and your reputation. It also gives the startup clarity, which makes the relationship work better in practice. This page helps UK consultants understand what should be in an advisory agreement, what to watch out for, and how to use Atornee to draft or review one without paying solicitor rates for a first pass.

Why this matters

Most UK consultants stepping into an advisory role get handed a one-sided agreement drafted by the startup's founder or their cheap template service. It's usually light on your protections and heavy on theirs. Common problems: vague scope that lets the startup demand more than you agreed to, IP assignment clauses that hand over everything you contribute, no clarity on equity vesting if the relationship ends early, and confidentiality obligations that run one way. You end up doing real strategic work with no written record of what was agreed. When things go wrong — and sometimes they do — you have nothing to stand on. That's the problem this page addresses.

The Atornee approach

Atornee lets you draft or review a consultant advisory agreement in plain English, with AI that understands UK contract law context. You're not filling in a generic template and hoping for the best. You describe your situation — the startup, the scope, the equity or fee arrangement — and Atornee helps you build a document that reflects it. It flags clauses that are weighted against you, explains what standard UK advisory terms look like, and helps you push back on language before you sign. It's not a substitute for a solicitor on a complex deal, but for most early-stage advisory arrangements, it gets you to a solid first draft or a clear review without the hourly rate.

What you get

A clear scope of services clause that defines exactly what advisory input you're committing to, so you're not on the hook for unlimited demands
IP ownership provisions that protect any pre-existing knowledge, tools, or frameworks you bring to the role
Equity or fee terms with vesting schedules and what happens if the relationship ends before the vesting period completes
Confidentiality obligations that run both ways, not just binding you to the startup's secrets
Termination rights that let either party exit cleanly, with notice periods and post-termination obligations spelled out

Before you sign checklist

1
1. Agree the basics verbally first — scope, time commitment, compensation, and duration — before drafting anything
2
2. Check whether the startup wants to assign all IP you create during the advisory role, and decide whether you're comfortable with that
3
3. Confirm whether you're being engaged as a self-employed consultant or in any other capacity, as this affects tax and IR35 considerations
4
4. Use Atornee to draft the agreement or upload the startup's draft for a clause-by-clause review
5
5. Pay particular attention to the IP assignment, non-compete, and confidentiality clauses — these are where consultants most often get caught out
6
6. If equity is involved, make sure the vesting schedule, cliff period, and good/bad leaver provisions are explicitly written in
7
7. If the deal is high value or involves significant equity, get a solicitor to review the final draft before you sign

FAQ

Does a UK consultant advisory agreement need to be in writing?

No, but you'd be taking a serious risk without one. Verbal agreements are technically enforceable in the UK, but proving what was agreed is almost impossible when things go wrong. If equity is involved, you absolutely need something in writing. Courts won't invent terms for you.

Who owns the IP I create as a startup advisor in the UK?

It depends entirely on what your agreement says. Under UK law, there's no automatic rule that hands IP to the startup just because you created it in an advisory context. But many startup agreements include broad IP assignment clauses that do exactly that. Read the clause carefully. If you're bringing pre-existing frameworks or tools, make sure they're carved out explicitly.

What's a reasonable equity stake for a UK startup advisor?

There's no fixed standard, but early-stage advisor equity in UK startups typically ranges from 0.1% to 1%, depending on the advisor's seniority, the stage of the company, and the time commitment involved. SEIS/EIS implications can also affect how equity is structured. This is worth discussing with an accountant if the numbers are meaningful.

Can I use an AI tool like Atornee to draft my advisory agreement instead of a solicitor?

For most early-stage advisory arrangements, yes — Atornee can get you to a solid, UK-appropriate draft or help you review a startup's proposed agreement. Where you should escalate to a solicitor: if significant equity is involved, if there are complex IP considerations, or if the startup is pushing back on terms and you're heading toward a negotiation.

What should a UK consultant advisory agreement always include?

At minimum: scope of services, time commitment, compensation or equity terms, IP ownership, confidentiality obligations, termination rights, and governing law (which should be England and Wales, or Scotland if applicable). Anything missing from that list is a gap that could hurt you.

Is an advisor agreement the same as a consultancy agreement in the UK?

Not exactly. A consultancy agreement typically covers a defined project or ongoing service delivery. An advisory agreement is usually lighter on deliverables and heavier on strategic input, often with equity rather than fees as compensation. The legal structure can overlap, but the commercial intent is different and the document should reflect that.
