The agency

What data consultants do

Hiring? Brief us and we come back with a shortlist of 3–5, each with rate, availability and IR35 position set out. Looking for the work? The board below shows current data leadership roles.

A data consultant at this level owns the data strategy, governance and platform direction, leads the analysts and engineers, and tells the leadership team what the data can and cannot support. The chief data officer owns data as an asset: strategy, governance, quality, analytics and the platforms behind them.

Companies searching for a data consultant at leadership level want a fractional data consultant: a chief data officer or head of data who sets strategy and governance a few days a week. See fractional chief data officer.

Data consultants are not a firm’s junior team: each is one senior person who contracts with the company directly. Fractional Quest is the recruitment agency that finds them; the service side is on data consultancy.

The scope

What a data consultant owns

The scope. The data strategy and how data supports decisions; data governance, ownership and quality; the data platform, warehouse and analytics stack; reporting, analytics and the data team; data protection by design, working with the DPO.

Out of scope. Legal data protection compliance is the DPO’s independent remit. Product engineering and core infrastructure sit with the CTO and CIO.

The neighbouring seats. The CDO owns the value and governance of data; the DPO independently advises on its lawful use; the CTO owns the systems that store it.

The process

How does a brief become a shortlist?

Six steps, one accountable person at each. We don’t promise a shortlist by a date; the weeks below are what a well-scoped brief usually takes.

Against the alternatives

Four ways to buy data expertise fractional, project, interim or permanent

The same data problem can be bought four ways. The difference is who does the work, for how long, and who is accountable afterwards.

The decision

Which data consultant to hire

Match the shape to the work, not the title.

  • Weekly judgementA fractional data consultantA fractional chief data officer sets the strategy, governance and platform direction on a standing weekly commitment and lets the analysts and engineers deliver it.
  • Now, full-timeAn interim data leadA warehouse or platform migration needs a senior owner. An interim CDO leads it full-time to go-live.
  • For yearsA permanent hireA permanent chief data officer is right when data is a core product or revenue stream, or the data organisation needs full-time executive leadership.

Vetting

How do we vet a data consultant?

Five stages before anyone reaches a shortlist of three to five.

  1. Pedigree screen
    Tenure
    We verify prior tenure in the seat, at the scale and stage you need. No consultant presenting as an executive.
  2. Mandate fit
    Fit
    Fit to your stage, sector and the problem the seat exists to solve, not a CV keyword.
  3. Reference deep-dive
    Verify
    We take references ourselves, from recent clients and boards: what they delivered, not what they titled it.
  4. Shortlist
    Shortlist
    Three to five candidates, each with day rate, availability and IR35 position set out.
  5. Kick-off
    Start
    Scope, first-month outcomes and the contract agreed before day one.

The full process is on how we vet.

how to hire

How to hire a data consultant four steps

Write down the decisions. List the three decisions the data consultant will own in the first ninety days. That list decides the shape: weekly decisions point to fractional, a time-bound change to interim, a full-time load to permanent.

Brief us. Scope, days, start date and what success looks like. We search for your brief and assess through our five-stage vetting.

Compare a shortlist. 3–5 data consultants, each with day rate or salary, availability and IR35 position set out, so you compare like with like.

Contract directly. The data consultant contracts with you, usually through their own company for fractional and interim work. Write the contract to match how it will actually run.

what to check

What to check in data consultants before you sign

Evidence, not titles. Ask for platforms they owned to go-live and how adoption went, and check they understand UK GDPR in practice: the ICO’s guidance on AI and data protection is the reference most data leaders now need.

Professional bodies. the ICO’s guidance on AI and data protection — how UK GDPR applies to AI systems and to decisions made with AI; BCS, The Chartered Institute for IT — the chartered body for IT, whose Professional Register is a public record of technology professionals.

Status. It depends on how the engagement runs in practice — control, substitution and whether the data consultant is part and parcel of your organisation, not on the label "consultant". For medium and large private-sector clients the client makes the status determination. Every candidate on our shortlist states their IR35 position.

Capacity. A fractional data consultant holds other clients. Ask how many, which days are yours, and how urgent issues are handled between them.

for consultants

Work as a fractional data consultant what the work looks like

Fractional data leadership suits heads of data and chief data officers who have built a function and a platform and want a portfolio of clients.

Briefs arrive as fractional (days a week, ongoing), interim (full-time, fixed term) or permanent roles. The board on this page shows current data leadership roles, labelled by engagement; every fractional role is on the fractional jobs board.

Companies hire the leader, not the label: set out the decisions you have owned, the outcomes, and the days you can commit. Your IR35 position and rate go on the shortlist as you state them.

The right route

Agency, recruiter, interim or permanent?

Three taps. Say how much senior work there is, for how long, and whether it is one leader or a run of hires; the tool names the route.

Brief a fractional recruitment agency.

Senior judgement for part of the week: a fractional CFO, CTO, CMO or COO on one to three days. We come back with a shortlist of three to five, each with day rate, availability and IR35 position set out.

We recruit executives. We don’t supply embedded fractional recruiters; where that is the right route, the tool says so.
