What Happens to Your Business Data When You Hire an AI Consultant? A UK GDPR Guide

Your business stays in charge of your data. Under UK GDPR you are the controller, the consultant and the AI services they use are processors, and you should have a written agreement saying what they can do with it, where it is stored and how it gets deleted when the work ends.

That is the short version. Here is what it means in practice, and the questions I would expect any small business owner to ask me before handing anything over. This is a plain English guide, not legal advice. If your data is sensitive, a short chat with a data protection specialist is money well spent.

Who controls the data

UK GDPR, alongside the Data Protection Act 2018, splits the roles in two.

The controller decides why personal data is used and how. That is you. Your customers gave their details to your business.

A processor handles the data on your instructions. A consultant who builds and maintains a tool for you is a processor. So are the services the tool runs on: the AI model provider, the email service, the database host.

You keep the responsibility as controller. That is why it matters who you hire and what they set up.

The contract you need

When a processor handles personal data for you, the law expects a written contract covering it. It is usually called a data processing agreement. It should say what data is handled, for what purpose, how it is kept secure, who else is involved, and what happens to it when the work ends.

A good consultant will raise this before you do. If they look blank when you ask, that tells you something.

Where your data actually goes

Ask for a simple list. Which services will the tool use, and where does each one store data?

Many AI providers are based in the United States. Sending personal data abroad is allowed under UK rules when the right safeguards are in place, but you should know it is happening and which safeguards cover it. A consultant should be able to name each service and point you to its data terms.

Also ask whether the AI provider uses your data to train its models. Most business API plans say they do not by default, but the consumer apps can be different. Check the terms for the plan actually being used.

How I handle it on my own projects

The accounts the tool runs on are set up in your name, so the data sits in services you control and can close. I only send the AI model the parts of a record it needs for the job. A quote tool needs the job description, not the customer's full history.

Where possible, the tool drafts and you approve, so nothing personal is sent out to anyone without a person seeing it first. And when a project ends, I remove my own access. You can check that yourself, because the accounts are yours.

Deletion and the right to erasure

Your customers have the right to ask for their data to be erased in many situations. If they ask, you need to be able to remove it from everywhere it lives, including the tools a consultant built.

So before a build starts, ask: if a customer asks to be deleted, how do I do it? The answer should be a short, specific set of steps, not a shrug.

Questions to ask before you hand over any data

What personal data will the tool use, and why does it need each part? Which services will hold it, and in which countries? Will any provider use it to train models? Whose name are the accounts in? What happens to the data and to your access when the project ends? How do I delete one customer's records if they ask?

If a consultant can answer those clearly, you are in good hands. For more on what you should own at the end of a project, see what an AI consultancy project includes, and for the general vetting checklist, how to choose an AI consultant.

Quick answers

Who owns my data when I hire an AI consultant?

You remain the controller of your customers' personal data under UK GDPR. The consultant and the services the tool uses act as processors on your instructions.

Do I need a data processing agreement with an AI consultant?

If they will handle personal data for you, yes. UK GDPR expects a written contract with any processor covering what data is used, for what purpose, how it is secured and what happens at the end.

Is it legal to send customer data to US AI services?

It can be, when the right transfer safeguards are in place. Ask your consultant which services are used, where they store data and which safeguards apply.

Will AI providers train on my business data?

Most business API plans say they do not by default, but terms differ by plan and provider. Ask which plan is being used and check its data terms.

How do I delete a customer's data from an AI tool?

Ask for written steps before the build starts. Because the accounts should be in your name, you should be able to remove records yourself.
