Advisory Agreement Template for UK Startups

If you are bringing on an advisor for your UK startup, you need a proper startup advisor agreement template startup uk founders can actually rely on. A handshake deal or a generic US-style template downloaded from the internet will not protect you. UK advisor agreements need to cover equity vesting schedules, IP assignment, confidentiality, and the advisor's status as an independent contractor under UK law — not employment law. Get any of those wrong and you risk a messy dispute over who owns what, or worse, an advisor claiming worker rights they were never meant to have. This guide explains what a solid UK startup advisory agreement must include, where most founders go wrong, and how Atornee helps you generate a legally grounded document without paying solicitor rates for a first draft. If your situation involves complex equity structures or regulated activities, we will tell you when to escalate to a qualified solicitor.

Why this matters

Most UK founders bring on advisors informally, then scramble to paper the arrangement months later when something goes wrong — equity expectations clash, the advisor shares sensitive information, or they claim they contributed to core IP. Generic templates pulled from US startup communities do not account for UK contract law, HMRC's IR35 considerations, or the Companies Act implications of equity grants. Even UK-labelled free templates often miss critical clauses or use boilerplate that does not reflect how early-stage UK startups actually operate. The result is a document that looks official but leaves you exposed on the things that matter most.

The Atornee approach

Atornee is not a template library. When you use Atornee to generate a startup advisory agreement, the output is shaped by your specific situation — the type of advisor, whether equity is involved, the sensitivity of information they will access, and the scope of their role. You answer plain-English questions and get a document built around UK law, not a US precedent with the dollar signs swapped out. You can edit, download, and use it immediately. If the tool flags complexity that warrants a solicitor review, it tells you directly rather than pretending the document covers everything.

What you get

A UK-specific advisory agreement covering scope of services, time commitment, and deliverables — so both sides know exactly what is expected
Equity and compensation clauses with vesting schedules appropriate for UK startup advisor arrangements, including cliff and reverse vesting options
IP assignment language that ensures any work or introductions the advisor contributes belong to your company, not them
Confidentiality provisions drafted for UK law, protecting your trade secrets, customer data, and business strategy
Independent contractor status clauses that reduce the risk of an advisor later claiming employment or worker rights under UK legislation

Before you sign checklist

1
1. Define the advisor's role clearly before drafting — what they will do, how many hours per month, and for how long
2
2. Decide upfront whether you are offering equity, cash, or both, and confirm any equity grant is consistent with your cap table and articles of association
3
3. Check whether the advisor will have access to confidential information, customer data, or regulated materials — this affects which clauses you need
4
4. Confirm the advisor is genuinely self-employed and not working in a way that could trigger IR35 or employment status concerns
5
5. Use Atornee to generate a first draft tailored to your answers, then review the output before sending it to the advisor
6
6. Have both parties sign the agreement before the advisor starts any work or receives any confidential information
7
7. If equity is involved or your startup is in a regulated sector, have a UK solicitor review the final document before execution

FAQ

Does a UK startup advisor agreement need to be signed before the advisor starts?

Yes, and this is where most founders get caught out. If an advisor starts work, receives confidential information, or contributes ideas before signing, you may have limited ability to enforce IP assignment or confidentiality retrospectively. Get the agreement signed before any substantive engagement begins.

Can I use a US startup advisor agreement template for my UK company?

You should not. US templates reference Delaware law, US tax treatment of equity, and legal concepts that do not map onto UK company law or HMRC rules. Using one creates ambiguity at best and unenforceable clauses at worst. You need a document governed by English law and drafted with UK-specific considerations in mind.

What equity vesting terms are standard for UK startup advisors?

There is no single standard, but a common structure is a one-year cliff with monthly vesting over two years, with equity typically ranging from 0.1% to 1% depending on the advisor's seniority and involvement. The agreement should specify what happens to unvested equity if the relationship ends early. Always check with your accountant or solicitor on the tax treatment of any equity grant.

Does an advisory agreement protect my IP if the advisor contributes ideas?

Only if it includes a clear IP assignment clause. Without one, an advisor who contributes to your product, code, or creative work may have a claim to that IP under UK copyright or design law. A well-drafted agreement assigns all IP created in connection with the advisory role to your company from the outset.

Is a startup advisor an employee under UK law?

Not automatically, but the label in the contract does not determine the legal reality. If an advisor works regular hours, is integrated into your team, or is economically dependent on your startup, HMRC or an employment tribunal could view them differently. Your agreement should reflect the genuine nature of the relationship, and the working arrangement should match what the contract says.

When should I get a solicitor to review my advisor agreement instead of using a template?

If the advisor is receiving significant equity, has access to highly sensitive IP or regulated data, is operating in a sector like financial services or healthcare, or if there is any ambiguity about their employment status, a solicitor review is worth the cost. Atornee will flag these situations in the generation flow rather than letting you proceed with a document that may not be sufficient.
