Advisory Agreement Template for UK Small Businesss

If you are bringing on an advisor for your UK small business, you need a startup advisor agreement template small business uk that actually reflects how these relationships work in practice. A handshake deal or a generic one-page template downloaded from a random site will leave you exposed on equity, IP ownership, confidentiality, and what happens when the relationship ends badly. UK advisory agreements have specific considerations around equity vesting, Companies Act compliance if shares are involved, and HMRC treatment of advisor compensation. Most free templates ignore all of this. This page explains what a proper UK small business advisory agreement must include, where generic templates fall short for founders at the early stage, and how Atornee helps you generate a document that is fit for purpose without paying solicitor rates for a first draft. If your situation involves complex equity structures or regulated activities, escalating to a solicitor is the right call and we will tell you when.

Why this matters

Most UK small business founders bring on advisors informally. Then six months later there is a dispute about whether the advisor owns any IP they contributed, whether their equity has vested, or whether they can walk straight to a competitor. Generic advisory agreement templates downloaded for free rarely cover UK-specific equity vesting mechanics, IR35 considerations for advisor engagements, or what happens to shares if the advisor does nothing. The result is either a document that gives you false confidence or a relationship that sours with no clear legal framework to fall back on. Founders need something built for the UK context, not a US template with the dollar signs swapped out.

The Atornee approach

Atornee generates advisory agreements built around UK legal norms, not US startup boilerplate. You answer a short set of questions about your advisor relationship — compensation type, equity or cash, IP expectations, confidentiality needs, duration — and Atornee produces a structured draft that reflects those specifics. It is not a static template you fill in manually. The output covers the clauses UK founders actually need: vesting schedules, IP assignment, termination triggers, and non-solicitation. You get a working first draft in minutes. If your situation flags complexity — regulated sectors, significant equity, or existing shareholder agreements — Atornee will tell you to take it to a solicitor before signing.

What you get

A UK-specific advisory agreement draft covering equity or cash compensation, IP assignment, confidentiality, and termination — generated from your actual inputs, not a blank template
Vesting schedule language appropriate for UK small businesses, including cliff and monthly vesting options that align with how advisors typically earn equity here
Clear IP ownership clauses so any work, introductions, or materials your advisor contributes belong to your business, not them
Termination and post-termination provisions including what happens to unvested equity and whether non-solicitation applies after the relationship ends
Plain-English explanations of each clause so you understand what you are signing before you send it to your advisor

Before you sign checklist

1
1. Decide before drafting whether your advisor is being compensated with equity, cash, or both — this shapes the entire agreement structure
2
2. Check whether any equity grant requires board approval or conflicts with your existing shareholder agreement or articles of association
3
3. Confirm the advisor's status — are they acting as an individual or through a limited company — as this affects tax treatment and IR35 considerations
4
4. Define the scope of the advisory role clearly before generating the document so the obligations clause reflects what you actually expect from them
5
5. Decide on confidentiality requirements upfront — if your advisor will access sensitive commercial information, a standalone NDA or strong confidentiality clause is non-negotiable
6
6. Review the generated draft against your existing cap table and any investor side letters before sending to the advisor
7
7. If the advisor is receiving shares rather than options, take the final document to a solicitor or accountant before execution to confirm Companies Act and HMRC compliance

FAQ

Does a UK advisor agreement need to be signed by a solicitor to be legally valid?

No. A contract between two parties is legally binding in the UK once there is offer, acceptance, consideration, and intention to create legal relations. You do not need a solicitor to draft or witness it for it to be enforceable. That said, if equity is involved or the agreement interacts with your articles of association, having a solicitor review the final version before signing is worth the cost.

What is a standard equity percentage for a startup advisor in the UK?

There is no fixed standard, but early-stage UK startups typically offer advisors between 0.1% and 1% of equity, depending on the advisor's seniority, the stage of the business, and how active the advisory role is. Equity is almost always subject to a vesting schedule — commonly a one-year cliff with monthly vesting over two years. Giving equity without vesting is a common and costly mistake.

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

You can, but you probably should not. US templates reference Delaware corporate law, use option structures that do not map cleanly to UK EMI or unapproved options, and often omit clauses that matter under English law. They also tend to ignore UK-specific tax treatment of advisor equity. Using a US template creates ambiguity that could cause real problems if the relationship breaks down.

What happens to an advisor's equity if they stop being useful or go quiet?

If your agreement has a proper vesting schedule and a termination clause, unvested equity lapses when the agreement ends. Without those clauses, an advisor who does nothing for two years may still have a claim to the equity you originally agreed. This is one of the most common and avoidable problems in early-stage advisor relationships. Always include vesting and a clear termination trigger.

Do I need a separate NDA if my advisory agreement has a confidentiality clause?

Not necessarily. A well-drafted confidentiality clause within the advisory agreement can cover the same ground as a standalone NDA. However, if you are sharing sensitive information before the advisory agreement is signed — during early conversations — a separate NDA signed upfront makes sense. You can use both without conflict.

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

They overlap but are not the same. A consultancy agreement typically covers a defined scope of work with deliverables and payment terms. An advisory agreement is usually looser — it covers ongoing strategic input, introductions, and guidance rather than specific outputs. The distinction matters for tax, IR35 assessment, and how you structure compensation. If your advisor is doing project-based work, a consultancy agreement may be more appropriate.
