Consulting Agreement Review Checklist: What to Check Before You Sign

If you're about to sign a consulting agreement, this consulting agreement review checklist for UK businesses will help you spot what matters before you commit. Consulting agreements vary wildly — some are fair, some are one-sided, and a few contain clauses that could seriously limit your business or expose you to unexpected liability. The problem is most founders and operators sign them without reading past the rate and the start date. This page walks you through the key clauses to check, the red flags that should make you pause, and the points where you genuinely need a solicitor rather than a checklist. UK-specific considerations apply throughout — including IR35 status, intellectual property ownership under UK law, and data protection obligations under UK GDPR. Whether you're the business hiring a consultant or the consultant being hired, the same risks apply from different angles. Use this as your starting point before you sign anything.

Why this matters

Most consulting agreements land in your inbox as a fait accompli — drafted by the other side, in their favour, with a tight turnaround. You're busy, the relationship feels good, and the temptation is to skim and sign. But consulting agreements regularly contain clauses that restrict your ability to work with competitors, assign your IP to the client without fair compensation, or leave payment terms dangerously vague. Getting this wrong costs real money. A poorly reviewed consulting agreement can mean unpaid invoices, disputed ownership of work you created, or unexpected tax exposure if IR35 is mishandled. This page exists to help you slow down for thirty minutes and check the things that actually matter.

The Atornee approach

Atornee lets you upload your consulting agreement and get a structured review in minutes — not days. It flags problematic clauses, explains what they mean in plain English, and tells you whether a clause is standard, negotiable, or a genuine red flag. It won't replace a solicitor for complex or high-value engagements, and it won't pretend to. What it does is get you from 'I have no idea what I'm looking at' to 'I know exactly what to push back on' before you spend money on legal advice. For UK businesses dealing with routine consulting agreements, that's often exactly what's needed.

Plain-English explanations of IP ownership, non-compete, and payment terms so you know what you're actually agreeing to
Specific red flag language to watch for — including clauses that could affect IR35 status or assign your IP by default
Guidance on which issues are worth negotiating and which require a solicitor before you proceed
A repeatable review process you can use every time a new consulting agreement comes in

Before you sign checklist

1
1. Identify who drafted the agreement — the drafting party's interests are usually baked into every clause, so read with that in mind
2
2. Check the scope of services clause — vague scope leads to scope creep disputes; it should describe deliverables, not just general activities
3
3. Review IP ownership provisions — confirm who owns work created during the engagement and whether any assignment is automatic or conditional
4
4. Examine payment terms, invoicing requirements, and late payment provisions — UK law gives you statutory interest rights under the Late Payment of Commercial Debts Act 1998, but your contract can override this
5
5. Check any non-compete, non-solicitation, or exclusivity clauses — assess how long they run, what they cover, and whether they're proportionate to the engagement
6
6. Look for termination rights on both sides — understand what notice is required, whether payment is owed on early termination, and what happens to work in progress
7
7. Upload the agreement to Atornee for a structured clause-by-clause review before you respond to the other side or sign

FAQ

What should I look for when reviewing a consulting agreement in the UK?

Focus on five areas: scope of services, IP ownership, payment and invoicing terms, termination rights, and any restrictive covenants like non-competes. These are where disputes most commonly arise. Also check whether the agreement correctly reflects the working relationship for IR35 purposes if you're a contractor operating through a limited company.

What are the biggest red flags in a consulting agreement?

Watch for automatic IP assignment with no carve-out for pre-existing materials, broad non-compete clauses that run for more than 12 months or cover an unreasonably wide market, vague scope of services that could be interpreted to include unlimited work, and payment terms that give the client sole discretion to withhold payment. Any clause that says the client can terminate immediately without payment for work already done should also be challenged.

Does a consulting agreement affect IR35 status in the UK?

Yes, significantly. The wording of your consulting agreement is one of the factors HMRC considers when assessing IR35 status. Clauses that imply personal service, control over how work is done, or an obligation to accept all work offered can push an engagement inside IR35. If IR35 is a concern for your engagement, get specific advice from a tax adviser or solicitor — this is not an area to handle on a checklist alone.

Who owns the intellectual property created during a consulting engagement?

Under UK law, IP ownership in a consulting context does not automatically transfer to the client — unlike employment, where it typically does. The agreement needs to explicitly assign IP to the client if that's the intention. If there's no assignment clause, the consultant usually retains ownership and grants a licence. Always check what the agreement says, and if you're the consultant, consider whether you need to carve out pre-existing tools, templates, or methodologies.

Can I negotiate a consulting agreement even if the other side says it's standard?

Yes. 'Standard' usually means 'standard for us' — it doesn't mean non-negotiable. Most commercial parties expect some pushback on consulting agreements, particularly around IP, payment terms, and restrictive covenants. Identify the two or three clauses that matter most to you and focus your negotiation there rather than redlining everything.

When should I get a solicitor to review my consulting agreement rather than doing it myself?

Escalate to a solicitor if the contract value is high, if there are complex IP provisions involving pre-existing technology or software, if the non-compete or exclusivity terms would materially affect your ability to work, or if there's any ambiguity around IR35 status. For routine, lower-value engagements with straightforward terms, a structured AI review followed by your own judgment is often sufficient.
