Setting evidence rules for a branding-agency directory

An England branding-agency directory needs a defined supplier register, not a market total. No dataset isolates suppliers of brand strategy, naming, identity and governance, and no public release measures English client spending. The sources below can provide context or help check a lead, but cannot establish a complete list or rank agencies. Research closed on 5 September 2026. Government and regulator evidence usually covers the UK and applies in England unless stated; creative-sector figures remain UK-wide unless regionalised.

No agency supplied data or paid for inclusion, and no buyer interviews or assignments were conducted. This guide sets out how to define a supplier entry, check public evidence and record what remains unknown; it does not provide agency listings, reviews or a verified count. A credible directory should separate checkable evidence from unverified claims rather than imply completeness.

Define the directory's context and limits

DBT's estimate of 5.0 million private-sector businesses in England at the start of 2025, published on 2 October 2025, provides broad context for the business population around a directory. It combines registered firms with estimates for unregistered businesses, so it cannot identify likely branding buyers, qualifying agencies or current demand.

Geography follows head-office location, while government and not-for-profit bodies are outside the main population. The series is labelled official statistics in development. Neither a head-office total nor an estimate containing unregistered firms is a directory of potential clients or suppliers, or evidence that an included business needs brand work now.

Use registered records to check identity, not services

ONS UK Business: activity, size and location 2025 covers enterprises and local units registered for VAT or PAYE. Released on 24 September 2025, it separates records by industry, region, legal status, employment and turnover bands; ONS quality information helps explain the statistical series.

Registration combined with an industry match does not prove that a business buys agency services, can deliver branding work or has a reason to commission it. An enterprise and a local unit are distinct counting units, so a directory count must name its unit and must not substitute or combine them without explanation.

Do not treat creative-sector totals as supplier counts

The DCMS Creative Industries business-demographics report uses a March 2025 IDBR snapshot. It counted 269,655 UK creative-industry businesses, with 93.4% in the micro employment band, and 278,215 business sites, of which 33.9% were located in London.

A business is an enterprise and a site is a local unit. The creative-industry definition spans several subsectors and does not isolate branding specialists. These UK-wide figures show creative-sector scale and location; they cannot be relabelled as an England agency count or as the number of suppliers available to branding clients.

Keep broad economic measures out of directory profiles

DCMS put UK advertising and marketing GVA at £24.3 billion for 2024 in its provisional annual GVA release. Gross value added is not turnover, fee income or client expenditure, and the estimate covers a broader subsector than branding agencies.

The figure is UK-wide and partly modelled using national accounts and Annual Business Survey data. It cannot be converted into an England value by dividing by population or guessing an agency share. No official release provides England-only revenue for firms selling brand strategy, naming and identity, so a directory should not present a market total as a supplier profile or count.

Treat activity signals as leads, not endorsements

Enterprise births and deaths, trade mark filings and tenders can prompt research into a supplier or buyer, but they are not evidence of agency quality or completed work. Four demand indicators can help locate questions to investigate; general activity should not flow directly into a directory endorsement or sales claim.

ONS Business demography 2024 records births and deaths of registered enterprises and provides English regional tables based on the IDBR. Regional totals are rounded to the nearest thousand, while deaths for 2024 remain provisional. A new business might need a name and identity, keep its existing brand or never trade publicly, so a birth is not proof that a buyer commissioned branding work or that any named agency delivered it.

The IPO's 2025 facts and figures, published on 30 July 2026, records applications and registrations from UK registered-rights administration. The IPO cautions against relying on its IP statistics alone to describe innovation. Filings do not show which agency an applicant used, where creative work took place or a project's value, so they cannot verify an agency profile, client relationship or review.

A procurement notice can offer a more specific research lead because it may identify the organisation, scope and procedure. Cabinet Office central digital platform guidance, updated on 17 August 2026, says Find a Tender displays notices in one place and uses identifiers for organisations and procurements. Notices may change, close or prove unsuitable, so retain amendments and no-bid decisions and do not treat a notice alone as proof of supplier performance.

A procurement record or buyer account should be checked for the event, named organisation and authority to support the claim being made. Record the reason for change, affected audiences, approval route, deadline, purchasing mechanism and consequence of taking no action. Interest without a procurement path stays a research note, not verified evidence; buyer interviews can test the reason and authority.

Set an explicit supplier eligibility test

Set a written rule for which suppliers qualify before starting a directory count. One workable example requires public evidence of strategic positioning combined with naming or identity design, plus an implementation or governance handover. This makes inclusion inspectable rather than dependent on whether a business describes itself as a brand agency.

A production studio that only executes supplied artwork falls outside that example, as does a media agency without an identity service, even if either uses brand language. The rule also needs a counting unit: a legal entity, trading name, local office and freelance practice are not interchangeable.

One company may use several studio names, a network may contain several registered entities, and a sole trader may not appear as a company. Count each qualifying supplier once and retain deduplication evidence. State whether the result represents legal entities, trading names or another clearly specified unit.

Use industry codes as partial identity clues

UK SIC 2007 places potentially relevant activity in 73.11 advertising agencies, 70.21 public relations and communication, and 74.10 specialised design. Each class also includes activity beyond branding, so a principal register code can help locate a supplier but cannot confirm all of its services.

ONS completed SIC 2026 in April 2026. Its implementation note says official-output adoption requires staged changes to registers, survey samples and national accounts. Name the classification version and release vintage for every count. Do not join a SIC 2007 series to a later classification without a published correspondence and an explicit account of the break.

Distinguish service arrangements from supplier quality

A directory may need to distinguish four possible commissioning arrangements: a fixed project, a continuing stewardship retainer, an external team embedded for a period, and a multidisciplinary appointment combining identity with other services. These are possible buyer arrangements, not evidence of how English agencies usually operate or a rating of their quality.

A supplier profile can describe which arrangements it offers only when the information is supported by evidence. A one-off identity may be enough when the client has an internal owner and stable channels. A retainer can support repeated asset approvals, but its queue, response measure and renewal route need to be explicit.

Embedded work gives greater access while potentially blurring roles. Combining brand, campaign and digital services can reduce handovers, yet it creates additional approval gates that need separate evidence. When reviewing a profile, distinguish the arrangement described from evidence that the supplier has delivered it.

None of these arrangements supplies a fee benchmark. Ask each bidder to price the same scope, currency, VAT treatment, period, assumptions, revision limits, expenses and licence terms. Compare full economic cost, including buyer time and exit, without presenting individual bids as a general rate for England or a directory-wide rating.

Check the claims and responsibilities behind a profile

Commissioned brand assets can involve several forms of intellectual property. Government guidance says a self-employed creator usually owns commissioned work unless the contract assigns rights, and distinguishes copyright, designs and trade marks. A profile should not imply that a client owns every asset unless the relevant terms support that claim.

A project schedule should identify existing client property, agency tools, third-party licences and new work, then say what transfers and what remains licensed. These distinctions help a directory or review describe rights and handover accurately rather than treating a portfolio image as proof of ownership.

A company-name check is not a trade mark opinion. The IPO search service supports searches of UK marks by keyword, owner and other fields, but a qualified adviser should assess conflicts, classes and territory before a buyer adopts a name. Record who approved the final choice and which searches took place before describing a naming service or outcome.

Customer research, stakeholder interviews, mailing lists and campaign targeting may use personal data. ICO direct-marketing guidance was updated on 28 April 2026 for the Data (Use and Access) Act commencement schedule. It distinguishes identifying direct marketing, planning, collection and respecting objections across electronic communications; a creative brief does not grant permission to contact people. Do not present a supplier's research or marketing process as compliant without evidence.

A contract's label does not decide whether a party is a controller or processor. CAP system guidance says marketers carry principal responsibility for their communications, while agencies also have obligations around accuracy and misleading advertising. When reviewing a claim, identify who owns evidence for each objective statement and keep campaign approval distinct from identity approval.

Accessibility and security should not be sacrificed for visual consistency. WCAG 2.2 is a global web-content standard with testable success criteria, while the relevant UK legal position and target conformance level need qualified review for the service and channel. The NCSC small organisations guide offers a practical starting point for accounts, devices, backups and scam recognition. Treat these as review questions, not automatic endorsements.

A contract should identify systems, the access owner, the incident route and deletion evidence. These controls make responsibilities checkable during the engagement; a general security guide does not set the parties' specific arrangements. A directory or review should distinguish documented practices from claims that have not been checked.

Define supplier eligibility and entry evidence

Start from a dated supplier list and write the eligibility rule before counting. One workable test requires public evidence of brand strategy plus naming or visual identity, an active legal or sole-trader identity, and a stated ability to serve clients in England.

Exclude media-only agencies, production freelancers without strategic work, dormant companies and duplicate trading names. For each candidate, record:

Publish the eligible verified supplier count without extrapolation. An address does not prove current trading, and an England office does not establish England revenue. Official statistics describe the surrounding economy and classification limits, while the register counts a defined supplier set; publish the method and mark unresolved entries rather than imply certainty.

A directory count is not turnover and cannot be converted into turnover. Later, audience research can examine a defined buyer cohort, but the population and selection method still need to fit the question being asked.

Keep supplier counts separate from market claims

A verified supplier count is not a market outlook. A market outlook needs each input's unit, England geography, buyer cohort, observation period, source, retrieval date, exclusions, uncertainty and owner recorded alongside it.

qualifying suppliers with current evidence, deduplicated under the stated unit = published register count

Count only suppliers that meet the published rule, and retain the evidence for each inclusion or exclusion. Purchase incidence and spend require actual contracts or a study whose population matches the defined buyer. A directory, supplier survey or broad GVA release cannot fill those inputs because none measures relevant transactions on a matching basis.

A register can use three internal status cases without presenting them as market forecasts. A cautious case can reflect evidence loss or a narrower cohort; an active case uses entries with current evidence; and a review case flags records needing recheck. State the rule behind each status and do not turn the cases into a claim about market size.

Withdraw or recheck an entry when its source expires, the supplier definition changes or the evidence no longer supports inclusion. This stops old evidence supporting a directory claim after the underlying identity or service information has changed.

Set a publication gate for the directory

Publish a controlled register when the inclusion rule is clear, entries have traceable evidence and the team can maintain the promised scope. Give the register a defined coverage, named approvers, accessible presentation, secure record handling and a documented correction or removal route.

Hold publication if its market language depends on an untraceable total, entries mainly contain unauthorised claims, or the team cannot verify the stated service or identity. A weak evidence base or incomplete review capability should not be presented as a complete directory.

On publication day, recheck statistics, trade mark records, regulator guidance and procurement notices, and ask a named UK statistical reviewer to approve quantitative statements. Arrange qualified commercial, IP, privacy, advertising and accessibility review for relevant sections, alongside security and tax review.

The first useful target for a new register is not market share. It is a clearly defined supplier set whose identity, service evidence, inclusion decision and review status can be checked without filling gaps with an industry average.

Run the final commitment checks

Before publishing, verify that the supplier definition, evidence boundaries and counting method agree. The checks below keep broad population figures apart from verified entries, make public records traceable and ensure any commercial comparisons are based on equivalent terms.
