Data Protection Consultant: What They Do, When to Hire One

A data protection consultant works out what personal data your business holds, where it sits, who can see it, and what you are legally required to do about it. That can mean writing policies, running a data protection impact assessment, registering you with the ICO, or acting as your outsourced data protection officer if you are big enough to need one.

That is the straight answer. The longer answer is that "data protection consultant" covers a wide range of work, some of it legal and some of it technical, and most small businesses only need part of it.

I have also written about AI security and data governance on this blog, and the three overlap. Here is the difference. Security is about stopping something going wrong with an AI tool. Governance is about the policies and ownership that sit over your data generally. This post is about the narrower legal question: do you need a DPO, a DPIA, or just someone to look at a specific project and tell you where the line should sit.

I am not a solicitor and I do not hold a formal data protection qualification. What I do is build AI systems for small businesses in Greater Manchester and Cheshire, and most of those systems touch personal data somewhere. I have picked up a working knowledge of the practical side of this, specifically where AI and data protection meet. Where a business needs the legal side properly covered, I say so and point them elsewhere.

What a data protection consultancy actually does

Strip away the jargon and a data protection consultancy is normally doing some combination of the following.

Working out what data you hold and where. Most businesses are surprised by this exercise. Customer records in three different systems, old spreadsheets nobody has opened in years, a WhatsApp group with client phone numbers in it.

Writing or updating a privacy policy and data retention schedule, so you can say honestly what you collect, why, and how long you keep it. Getting the retention schedule right is really a data quality problem as much as a legal one. You cannot write down how long you keep something if you do not know where it lives in the first place.

Running a data protection impact assessment, usually shortened to DPIA, before you start anything new that is likely to result in high risk to individuals. That might mean processing personal data in large volumes, or in a sensitive way. This is not optional theatre. It is the document that makes you think through the risk before you build the thing, rather than after.

Handling a data breach if one happens, including whether it needs reporting to the ICO, generally within 72 hours of becoming aware of it, where that is feasible.

Training staff on what they can and cannot do with personal data day to day, which in my experience is the part that gets skipped most often and causes the most problems.

Data protection consultant versus data protection officer

These two phrases get used interchangeably and they are not the same thing.

A data protection officer, or DPO, is a specific legal role under UK GDPR. You are required to have one if you are a public authority, or if your core activities involve large scale systematic monitoring of individuals, or large scale processing of special category data such as health records. Most small businesses in Trafford and Cheshire do not meet that bar.

A data protection officer consultant is someone who takes on that formal role for you, usually part time, as an outsourced service. If you genuinely need a DPO under the law, this is a serious appointment with statutory duties attached. Appointing one does not transfer your organisation's own responsibility for compliance. It puts someone in the role whose job is to monitor and advise on it.

A general data protection consultant does advisory work without taking on the formal DPO role. Most of my clients fall here. They are not legally required to have a DPO. What they need is someone to look at a specific project, usually involving AI, and tell them honestly what the data risk is and what to do about it.

Worth checking before you hire anyone: do you actually need a DPO, or do you need advice. The government's data protection guidance sets out the thresholds, and it is worth reading the actual wording rather than relying on a consultant's summary of it, including mine.

Where this actually comes up in an AI project

I was working with a healthcare group with several clinics on a finance workflow. The finance lead spent part of every morning checking the previous day's appointments had been paid, cross referencing a booking system against an accounts package that do not talk to each other. One of her jobs ends with changing a batch of appointments in the booking system to mark them free of charge.

Could the AI have done that step as well. Technically, yes. We agreed it would not.

The AI got its own read only login. It works from reports and the diary, which is where the risk sits, so we scoped it to the reports and figures it actually needed rather than giving it open access to patient records. A data processing agreement and a data protection impact assessment were drafted before anything went near live data.

That decision, what the AI is not allowed to touch, mattered more than any of the technical build that followed. Writing it down first is what made the rest of the project possible to do responsibly.

This is the kind of data protection work that actually sits inside most AI projects. Not a compliance audit bolted on afterwards. A decision made at the start about where the line goes, which is also the starting point I use for AI consulting services more broadly.

The honest bit: when not to hire me for this

If your business is a public authority, handles large scale special category data such as health records as its core activity, or you suspect you need a legally appointed DPO, do not hire an AI consultant to cover that off. Hire a dedicated data protection consultancy or a qualified DPO who can take on the formal statutory duties. That is not false modesty. The role carries legal responsibilities that sit with a named person, and I am not the right person to hold it.

If you are already looking for that kind of specialist and not sure where to start, the ICO's own website lists what the role involves, which is a reasonable starting point before you brief anyone.

Where I do belong in this conversation is narrower and, I think, more useful for most small businesses. If you are about to connect an AI tool to customer records, a booking system, or financial data, and you want someone to look at what that tool would actually see, what it can be stopped from seeing, and whether you need a DPIA before you start, that is work I do often. It overlaps a lot with the AI security side of things, because most AI data risk in a small business is something somebody pasted into a chat window, not a sophisticated breach.

The Federation of Small Businesses found that 55% of its members now use AI, up from 20% in 2023, and that 92% are worried about the risks that come with it. That survey covers FSB's own members, who tend to be the more engaged firms, so treat the exact figures with some care. The direction is what matters. Most small firms are already using these tools, and almost all of them are uneasy about what goes into them.

What to ask before you hire a data protection consultant

A few questions worth putting to anyone offering data protection consultancy services, whether that is me or someone else.

Are you proposing to act as my formal DPO, or are you advising. These carry different levels of legal responsibility and you should know which one you are buying.

Will you write a DPIA for this specific project, or hand me a generic template. A template tells you nothing about your business.

What happens if there is a breach. Who do I call, and at what point in the first 72 hours.

If the answer to any of those is vague, that is the signal to keep looking.

Where to start

If you are planning to bring AI into a part of your business that touches personal data, the useful first step is working out what that AI tool would actually see, and where the line should sit on what it is allowed to touch. That is a conversation, not a sales pitch, and you can book one here. If it turns out you need a formally appointed DPO, I will tell you that too, and point you somewhere that can actually do it.
