Sourcing C-suite contact data in the UK

What are the eight standard C-suite roles in UK companies?

The term "C-suite" refers to senior executives whose titles begin with "Chief". In UK business, eight roles appear with sufficient consistency to form the working standard for data targeting:

• CEO / MD (Chief Executive Officer / Managing Director): the most senior operational executive. In UK private companies the title Managing Director is still common; listed companies typically use CEO.
• CFO (Chief Financial Officer): leads all financial functions. In smaller organisations this is often a Finance Director rather than CFO, but both map to the same targeting segment.
• COO (Chief Operating Officer): owns operational delivery. More common in businesses with complex supply chains or service operations.
• CMO (Chief Marketing Officer): heads marketing strategy. Many mid-market UK firms use Marketing Director rather than CMO; treat the two as equivalent for data purposes.
• CTO / CIO (Chief Technology Officer / Chief Information Officer): technology leadership. CTO typically owns product and engineering; CIO owns IT infrastructure. In smaller companies one person holds both.
• CHRO (Chief Human Resources Officer): HR and people strategy. Often titled HR Director or People Director in UK firms below 500 staff.
• CISO (Chief Information Security Officer): information security. This role is rare below 250 employees and primarily appears in financial services, healthcare, and technology sectors.
• Chairman: leads the board rather than managing operations. In privately held companies, the Chairman is often the founder; in listed companies, independence rules apply under the UK Corporate Governance Code.

Two things are immediately clear from this list. First, not every company carries all eight roles. A 30-person accountancy firm has an MD and possibly a Finance Director; it almost certainly does not have a standalone CMO or CISO. Second, title inflation means that "Chief X Officer" appears across many UK businesses where the holder is not a board-level executive at all. This matters when you are trying to buy or build a list: the role title alone is not a reliable proxy for seniority or decision-making authority.

C-suite role presence by UK company size

The table below maps which C-suite roles are realistically present at each UK employee size band. These are generalisations across sectors; financial services, regulated healthcare, and listed companies will carry more formal titles at lower headcount thresholds than, say, a regional trade business.

The practical upshot: if you are buying a C-suite list targeting companies with fewer than 50 employees, the deliverable contact is most often the MD and FD only. Requesting a COO or CMO for that size band will yield thin results or, worse, low-seniority contacts carrying inflated titles.

Why Companies House is the identity anchor for UK C-suite data

Companies House holds the statutory record of every director at every UK registered company. Under the Companies Act 2006, a company must file a director appointment (form AP01) within 14 days and a termination (form TM01) within the same window. That filing cadence is legally mandated, which is what makes the register useful as a data source: the information is current to within a fortnight, and the names and appointment dates are authoritative in a way that many secondary sources are not.

For C-suite targeting, Companies House captures CEO, CFO, COO, and Chairman where those individuals hold statutory director status. A CEO who is also a statutory director will appear on the register with their full name, residential service address (or registered company address if they chose that option), and the date they joined the board. That identity information can then be matched against corporate website biographies, press releases, and public filings to build out contact channels.

The key limitation is that Companies House records directors, not all C-suite executives. A CMO, CISO, or CHRO who is not on the board of directors will not appear in Companies House at all. For those roles, the public sources are corporate websites (About Us and Leadership pages), trade press announcements, and regulatory news service (RNS) filings for listed companies. Annual reports often contain executive committee rosters with photographs and brief biographies.

Board member vs executive committee member: a distinction that matters for data

UK corporate governance draws a clear line between the statutory board and the executive committee (ExCo). Board members are appointed under the Companies Act and appear on Companies House. ExCo members are appointed by the CEO and hold operational titles, but many of them are not statutory directors.

At FTSE 350 companies, the ExCo typically includes roles such as Chief People Officer, Chief Digital Officer, Chief Risk Officer, and Chief Customer Officer, none of which are standard board-level positions. The CEO and CFO usually sit on both the statutory board and the ExCo; everyone else on the ExCo may or may not be a statutory director depending on the company's governance structure.

For data sourcing, the implication is straightforward. A CISO or CHRO at a listed company will not appear in Companies House unless they have been appointed to the statutory board (which is unusual). Their presence in any data file depends entirely on whether they appear in publicly available secondary sources. That is a meaningful difference in data reliability compared with a CEO or CFO, and it is one of the reasons why quality C-suite files carry a pricing premium: compiling the non-statutory titles requires more source work.

Data freshness, decay rates, and the pricing premium for C-suite

C-suite contacts move more visibly than mid-management because their appointments and departures are public events. A CEO change at a listed company triggers an RNS announcement, press coverage, and a Companies House filing within days. That transparency is helpful for identifying the move quickly, but it also means C-suite lists go stale in a measurable, documented way.

UK CEO tenure averages four to six years, with CFOs slightly shorter at three to five years. COOs, CMOs, and CISOs often serve two to four years before moving. The churn is real: at any given point, around 15-20% of records in a compiled C-suite database may have changed within the past 12 months. Compare that with a Head of Finance or IT Manager, where tenures are typically longer and departures less publicly trackable, meaning the decay rate for mid-management data is often lower, even if the individual records are harder to verify initially.

This decay pattern drives the pricing premium buyers face for C-suite data. A supplier who is actively monitoring Companies House filings, RNS announcements, and corporate web pages for C-suite changes will price that monitoring into their refresh cycle. Expect to pay 20-40% more per 1,000 records for a C-suite file with a quarterly or monthly refresh guarantee versus a mid-management file with a six-month refresh. If a supplier quotes the same price for both and offers the same refresh frequency, ask exactly how they are tracking board-level changes: if the answer is vague, the freshness claim probably is not supported by active monitoring.

The PA layer and why direct-dial accuracy drops at C-suite level

Two structural factors make telephone contact harder at C-suite level than for Head of or Manager contacts.

Personal Assistants as call gatekeepers

At organisations of 250 staff and above, most C-suite executives work with a Personal Assistant (PA) who manages the diary and screens incoming calls. The telephone number that appears in data files for these contacts frequently routes to the PA's desk, not directly to the executive. This is not a data quality failure in the traditional sense: the number is real and associated with that person's office. It simply means your outbound caller will reach a PA first, not a direct dial (DDI) for the executive themselves.

In our experience, direct-dial numbers for C-suite contacts at companies above 500 staff are genuinely rare. A good data supplier will be transparent about this, distinguishing between switchboard or PA-screened lines and confirmed DDI numbers. If a supplier claims 90% direct-dial accuracy for enterprise-level C-suite contacts, the definition of "direct dial" is worth probing.

Personal mobiles vs business lines

C-suite executives in the UK use personal mobile numbers more than mid-management contacts do, partly because the role requires availability outside normal business hours, and partly because personal mobiles tend not to change when an executive changes employer. Business DDI numbers vanish the moment they leave a company; a personal mobile follows them.

The problem for data sourcing is that personal mobiles rarely appear in public corporate sources. Companies House does not record telephone numbers. Corporate websites list switchboard numbers and sometimes PA contacts, not executive personal mobiles. That gap in publicly available information means most C-suite data files carry business lines rather than mobiles, and cold calling those lines involves the PA layer described above.

There is also a PECR implication: calls to a number registered on the Telephone Preference Service (TPS) must not proceed regardless of whether the number is a business line or a personal mobile. C-suite executives who use personal mobiles for business may well have those numbers registered on TPS. Always screen your C-suite telephone list against TPS before any outbound call campaign.

Compliance for C-suite marketing: no shortcuts

C-suite contacts are still individuals, and UK GDPR, the Privacy and Electronic Communications Regulations (PECR), and the ICO's guidance apply to them in exactly the same way as to any other business contact. There is a common misconception that senior executives are somehow less protected or that cold outreach to them is inherently less risky. The ICO does not operate that way.

For email and postal marketing to C-suite contacts, legitimate interests under Article 6(1)(f) of UK GDPR is the correct lawful basis, provided you can complete a Legitimate Interests Assessment (LIA) documenting the purpose, necessity, and balancing tests. For an introduction to this process, see our guide on legitimate interests as the lawful basis for B2B data under UK GDPR.

For telephone outreach, screen every number against TPS every 28 days. This is a legal requirement under PECR, and a C-suite title on the record provides no exemption. Where a C-suite contact is sole trader or a senior partner in an LLP, the individual's TPS registration is binding even if you believe the call to be business-to-business in nature.

When compiling or buying C-suite data sourced from publicly available information (Companies House filings, corporate websites, public press releases), the SortedIQ B2B file is compiled under legitimate interests from public sources. No record in the file is described as opt-in: that is the correct UK GDPR characterisation for B2B data compiled from public corporate information. Buyers should conduct their own LIA before use.
