Questions to Ask Before Signing a Consulting Contract

You have chosen a consultant, you like the proposal and the start date is close. This is exactly when people stop asking questions and sign. A few more hours on the paperwork can prevent most of the disputes that arise later. This checklist sets out the consulting contract questions worth settling before you commit, grouped by theme, with notes on why each matters.

A word of caution: this is general information, not legal advice. For anything involving significant sums, sensitive data or complex ownership of work, have the agreement reviewed by a solicitor.

1. Who is contracting?

• [ ] What is the legal name and status of the supplier? A sole trader, limited company, partnership or LLP? Check company details at Companies House where relevant.
• [ ] Who will actually do the work? Named individuals, with their roles and approximate days.
• [ ] Can the consultant substitute someone else or subcontract? If so, with your approval and on the same confidentiality terms?

Why it matters: you are buying a particular person’s judgement. If a different, less experienced person turns up, the value changes.

2. What exactly is being delivered?

• [ ] Is the objective written down? The business outcome the project is meant to support.
• [ ] Are the deliverables listed? Reports, models, workshops, training, process designs.
• [ ] How will you decide a deliverable is acceptable? Acceptance criteria and a review period.
• [ ] What is explicitly out of scope? Exclusions prevent assumptions.
• [ ] What is the timetable and who is responsible for dependencies? If the consultant is waiting on your data, the delay should not be charged as the consultant’s failure, and vice versa.

Why it matters: vague scope is the commonest source of disagreements over cost and quality.

3. How are fees and expenses handled?

• [ ] Is the fee fixed, day-rate, retainer or performance-linked? Make sure the contract states which.
• [ ] For day-rate work, what is the estimated number of days and is there a cap?
• [ ] When are invoices issued and what are the payment terms?
• [ ] Is VAT included or additional?
• [ ] Which expenses can be charged, and is approval needed beyond a limit?
• [ ] How are changes in scope priced and approved? Ideally in writing before work begins.
• [ ] What happens if you pay late? Check interest or suspension clauses.

Why it matters: clarity on money protects the relationship. Surprises rarely appear for fixed items; they appear in “extras”.

4. Who owns what is created?

• [ ] Who owns the intellectual property in the deliverables? Typically you would want ownership or a broad licence to use the finished materials.
• [ ] Does the consultant keep ownership of pre-existing tools and methods? This is common and reasonable, but you should have a right to use them as part of the deliverables.
• [ ] Can the consultant reuse your data or materials for other clients? Usually this should be limited.
• [ ] Can the consultant refer to you as a client? Agree whether and how.

Why it matters: without clear terms, you might not be able to use a model or document freely after the project ends.

5. Confidentiality and data protection

• [ ] Is there a confidentiality clause? It should cover information shared by both sides and survive the end of the contract.
• [ ] Will the consultant handle personal data? If so, what personal data, for what purpose, and where will it be stored?
• [ ] Does the contract address UK GDPR? Roles (controller or processor), security measures, sub-processors, breach notification and deletion or return of data at the end.
• [ ] Which systems will the consultant access, and under what controls?
• [ ] Will devices or cloud tools used by the consultant meet your security standards?

Why it matters: a data incident is costly and your organisation may remain responsible. The Information Commissioner’s Office publishes guidance if you need a starting point.

6. Responsibility, liability and insurance

• [ ] What standard of work is promised? Often “reasonable skill and care”.
• [ ] Does the consultant carry professional indemnity insurance? At what level, and can you see a certificate?
• [ ] Is there a cap on liability? Many contracts limit the amount a supplier can be liable for. Understand the figure and what is excluded.
• [ ] Are there any guarantees or warranties? Be sceptical about promises of outcomes the consultant cannot control, and equally careful about disclaimers that remove any accountability.
• [ ] What is your own responsibility? For example, providing accurate information and making decisions.

Why it matters: if advice proves wrong, these clauses decide what recourse you have.

7. Working arrangements

• [ ] How often will you meet and who is the point of contact on each side?
• [ ] What access does the consultant need to people, premises and systems?
• [ ] What are the working hours and location?
• [ ] How will progress be reported?
• [ ] How will disagreements be raised and resolved? An escalation route avoids drift.

Why it matters: good intentions fail without a rhythm. A simple weekly check keeps problems small.

8. Employment status and tax

• [ ] Is the consultant genuinely independent? Consider how the working relationship operates in practice, not only what the contract says.
• [ ] Could the arrangement fall within rules on off-payroll working? These rules, often referred to as IR35 when an intermediary company is used, depend on the facts. Check HMRC guidance and consult a qualified adviser if unsure.
• [ ] Does the consultant supply their own equipment and bear their own costs?

Why it matters: misclassification can lead to tax and national insurance consequences.

9. Ending the contract

• [ ] Can either side terminate, and on how much notice?
• [ ] What happens to fees for work done up to termination?
• [ ] What must the consultant hand over if the contract ends early? Work in progress, documents and access credentials.
• [ ] What happens to your data? Return or secure deletion within a stated period.
• [ ] Are there break points between project phases? They allow you to stop without penalty if results disappoint.

Why it matters: a clean exit is easier to agree before relationships become strained.

10. Other clauses to read carefully

• Non-solicitation. Can you hire the consultant, or can they hire your staff?
• Conflicts of interest. Will they earn commission from products or suppliers they recommend? It should be disclosed.
• Governing law and disputes. Which law applies and how disputes are handled.
• Entire agreement and variation. The signed document should capture everything agreed, and changes should be in writing.

Finally, read the whole contract including schedules, check that promises in the proposal appear in it, and ask for anything unclear to be explained in plain English.

Frequently asked questions

Do I need a solicitor to review a consulting contract?

Not always for small, simple engagements, but it is sensible when the fees are substantial, the work involves sensitive data or ownership of valuable materials, or the terms look unusual. A short review is often modest compared with the cost of a dispute.

What if the consultant insists on their standard terms?

Standard terms are common and not necessarily a problem. Read them, flag clauses you cannot accept, and negotiate. Reasonable consultants expect some changes, particularly on scope, data protection and termination.

Is a purchase order enough?

A purchase order may record price and quantity but rarely covers confidentiality, ownership, liability or data protection. For consulting work, a proper agreement is safer.

Can I change the scope after signing?

Yes, through a documented change process. Agree in writing what changes, what it costs and how it affects the timetable, and avoid informal verbal additions.

Conclusion

A consulting contract should make the relationship easier, not more adversarial. Settle who is doing the work, what will be delivered, how you will pay, who owns the results, how data is protected, who is liable and how either side can leave. Walk through the checklist, ask for plain-English explanations and take legal advice where the stakes justify it. A little diligence now is the cheapest protection you will buy during the project.
