I Need to Hire a DPO But Don't Want to Add Headcount. What Are My Options?

It's a common dilemma for scale-ups: you've reached the point where data protection needs to be taken seriously — maybe due diligence is looming, a major customer has asked about your GDPR posture, or you've simply realised your current approach isn't going to hold up. You know you need a Data Protection Officer. But hiring one full-time feels like a significant commitment for a function that isn't your core business.

The good news is that the law is on your side here. UK GDPR explicitly permits the DPO role to be fulfilled by an external service provider. The question isn't whether you can outsource the role — you can — it's how to do it properly so that you get genuine expertise and real accountability, not just a name on a policy document.

This guide sets out your options, what the law requires, and what good looks like when appointing an external DPO.

Do I actually need a DPO?

Before exploring the options, it's worth confirming whether a formal DPO appointment is required in your situation.

Under UK GDPR Article 37, a DPO is mandatory if your organisation:

• Is a public authority or body
• Carries out large-scale, regular, and systematic monitoring of individuals (for example, behavioural advertising platforms or large-scale analytics businesses)
• Carries out large-scale processing of special category data or criminal conviction data (for example, health, biometric, or financial data at volume)

Many scale-ups don't technically fall into any of these categories — but that doesn't mean they should ignore the DPO question. If you process significant amounts of personal data, handle customer or employee data at scale, work with NHS or public sector bodies, or are preparing for due diligence, having a formally appointed DPO (or an equivalent senior privacy lead) is increasingly expected. Investors, enterprise customers, and regulators all look for evidence that someone credible owns data protection.

Even where appointment isn't strictly mandatory, the practical benefits of having an expert in the role are substantial. The ICO also makes clear that voluntary appointment still requires compliance with the full obligations set out in Articles 37–39.

What does UK GDPR say about outsourcing the DPO role?

Article 37(6) of UK GDPR is explicit: "The data protection officer may be a staff member of the controller or processor, or fulfil the tasks on the basis of a service contract."

In other words, the law is entirely comfortable with the DPO being external. What matters is not employment status, but whether the individual or service can fulfil the core obligations set out in Articles 38 and 39:

• Independence: The DPO must be able to perform their tasks without instruction on how to carry them out. They should not be dismissed or penalised for performing their role, and must report directly to the highest management level.
• Access and resources: The DPO must have sufficient access to data processing activities, systems, and staff to do the job properly.
• No conflict of interest: The DPO cannot hold a position that leads them to determine the purposes and means of processing personal data. For external providers, this is generally straightforward — but it's worth confirming that the provider has appropriate governance in place.
• Contact point for data subjects and the ICO: The DPO's contact details must be published and provided to the ICO. They must be reachable and responsive.

This framework shapes what an effective outsourced DPO arrangement looks like in practice. It's not just about having an expert on hand to answer questions — it's about genuine accountability and ongoing involvement in your compliance programme.

Your options when you don't want to add headcount

There are broadly three routes scale-ups take when they need DPO capability without a full-time hire. Here's an honest assessment of each.

Option 1: Appoint someone internally on a part-time basis

Some businesses designate an existing member of staff — typically someone in Legal, Compliance, IT, or Operations — to take on the DPO role alongside their existing responsibilities.

This can work in limited circumstances, but it comes with significant constraints. The ICO is clear that the DPO must have the expertise to carry out the role, and that they cannot be in a position of conflict of interest. Practically speaking, a COO who also determines data processing decisions, or a Head of Engineering who sets the technical architecture, is unlikely to satisfy the independence requirement.

The other challenge is that data protection is a broad and evolving discipline. Without genuine expertise, an internal appointee may end up providing a false sense of security rather than real compliance. The liability sits with your organisation either way.

Option 2: Hire a freelance privacy consultant

Privacy consultants are widely available and can be engaged on a project or retainer basis. This can provide genuine expertise, but the model has limitations that are worth understanding before committing.

Most consultancy arrangements are project-oriented — they produce documentation, run an audit, or advise on a specific question, and then disengage. The ongoing operational reality of running a data protection programme — monitoring, staff queries, incident management, DSAR handling, policy updates, regulatory changes — often falls back on an internal team that may not be equipped to handle it.

Consultants also vary widely in their expertise and sector knowledge. The DPO role requires more than legal familiarity with GDPR; it requires understanding of your specific data flows, your industry context, and the practical ability to engage across your organisation.

Option 3: Outsourced DPO service (DPO-as-a-service)

An outsourced DPO service provides a named, accountable DPO — typically supported by a broader privacy team — on an ongoing basis. This is increasingly the preferred model for scale-ups who want a serious privacy programme without the cost and commitment of a full-time hire.

The key advantages over a consultant are continuity, operational depth, and accountability. A well-structured DPO-as-a-service provider embeds themselves in your business, attends risk committee meetings, handles the regulatory and operational tasks that arise day-to-day, and maintains the ongoing documentation that makes compliance real rather than theoretical.

This is the model Trust Keith is built around. Rather than treating data protection as a periodic review, Trust Keith provides a dedicated privacy expert embedded in your team alongside an intelligent platform that operationalises compliance — handling data discovery, policy management, DSAR workflows, DPIA processes, and incident management in one place. It's the combination of people and platform that makes the difference between a programme that exists on paper and one that actually works.

What to look for in an outsourced DPO provider

If you decide that an outsourced DPO service is the right route — and for most scale-ups, it is — here's what to evaluate before making a decision.

• Genuine privacy expertise: Look for qualified professionals with recognised credentials (CIPP/E, CIPM, BCS or equivalent) and demonstrated experience in UK GDPR specifically. Post-Brexit, the UK regime has diverged from EU GDPR in meaningful ways — your DPO needs to understand the distinction.
• Sector experience: A DPO who has worked extensively with HealthTechs, FinTechs, or B2B SaaS businesses will understand the specific processing activities and regulatory pressures relevant to your context. Ask directly about their experience in your sector.
• Named, accountable individual: Your DPO should be a named person who can be registered with the ICO, who appears in your privacy notice as a contact, and who your team knows. "Access to a team of experts" is not the same as having a DPO.
• Proactive, not reactive: An effective DPO doesn't wait to be asked questions. They attend key meetings, flag emerging risks, stay across regulatory developments, and raise issues before they become problems. Ask providers how they stay across changes in ICO guidance and how they communicate these to customers.
• Platform or tooling support: Managing data protection at scale requires more than expertise — it requires a system. If your provider is working through spreadsheets and email chains, that's a red flag. Look for providers who combine expert support with structured tooling that keeps your records, workflows, and evidence organised and audit-ready.
• Availability and responsiveness: Data protection questions don't always arrive at convenient times. If a potential breach occurs on a Friday afternoon, or a DSAR lands during a busy period, your DPO needs to be reachable. Clarify response time commitments and escalation paths upfront.
• References from similar businesses: Ask for references from organisations at a similar stage and in a similar sector. How the provider performs for a 20-person tech company is quite different from how they perform for a 200-person scale-up preparing for Series B.

Red flags to watch for

Not all DPO services are equal. Here are the patterns that should prompt further scrutiny:

• Vague scope of service: If a provider can't clearly articulate what they will and won't do, how many hours are included, and what happens when issues arise outside normal scope, that's a problem. Get it in writing.
• No formal DPA: Your outsourced DPO provider will have access to significant personal data about your business and your data subjects. They should be prepared to sign a Data Processing Agreement that meets the requirements of Article 28 UK GDPR.
• Conflicts of interest: If a provider also offers services that involve determining how your data is processed — certain IT services, marketing services, or analytics functions — this can create a conflict that undermines the DPO's independence.
• One-size-fits-all approach: A template pack of policies and a quarterly check-in is not a DPO service. If the output looks identical regardless of your business, the provider hasn't understood what they're supposed to be doing.
• No accountability for outcomes: Ask what happens if the ICO investigates you. Does the provider support you through the process? Do they have professional indemnity insurance? These questions reveal a lot about how seriously they take the role.

Frequently asked questions

 

Can an outsourced DPO legally fulfil the role under UK GDPR?

Yes. Article 37(6) of UK GDPR explicitly states that the DPO may fulfil their tasks "on the basis of a service contract." There is no requirement for the DPO to be an employee. What matters is that they have the required expertise, independence, resources, and access to carry out the role as defined in Articles 38 and 39.

 

Do I need to register my DPO with the ICO?

There is no formal registration process for DPOs in the UK — the ICO does not maintain a public register. However, you are required to publish the DPO's contact details (name or role and email address) in your privacy notice, and to make them available to data subjects. Some organisations also share DPO contact details directly with the ICO as a point of contact, which is good practice. Full details are available in the ICO's DPO guidance.

 

What's the difference between a DPO and a privacy consultant?

A privacy consultant typically provides advice on specific questions or projects — they're engaged for a defined piece of work and then disengage. A DPO has an ongoing, defined legal role: advising on compliance, monitoring adherence to data protection law, cooperating with the ICO, and acting as a contact point for data subjects. A consultant can support a DPO but cannot replace one where a DPO is legally required. An outsourced DPO service provides the ongoing, accountable role — not one-off advice.

 

Can one person serve as DPO for more than one organisation?

Yes. Article 37(3) UK GDPR allows a DPO to be appointed for a group of undertakings, provided they are "easily accessible from each establishment." This is precisely the model on which most DPO-as-a-service providers operate — a named DPO with dedicated time and access for each customer, supported by a broader team. The key requirement is that the DPO can genuinely fulfil their obligations for each organisation they serve — this is worth verifying when evaluating providers.

 

What happens if I appoint an outsourced DPO and then the ICO investigates us?

Your outsourced DPO should be a material part of your response to any ICO investigation or enquiry. They are your registered contact point, they know your processing activities, and they should have the documentation and evidence to support your position. Ask any provider you're evaluating specifically what their approach is to regulatory engagement — and whether their professional indemnity insurance covers support through investigations. The strength of your DPO arrangement is tested precisely in these situations.
