Why no reliable UGC marketplace total exists for England, and how to study buyers and suppliers

No official dataset reports UGC marketplaces market size in England. A creator count, social-media audience figure, advertising total or broad agency statistic would not repair that gap. Each measures a different population and none identifies eligible marketplace transactions.

What to take away

Fix the market definition

For measurement, define a UGC marketplace as a service through which a participating creator and a buyer form or administer a commission for specified creator-made brand content. The study can include marketplace charges, but it should classify managed production, agency work, creator pay, paid media and rights fees separately.

Choose one unit before collecting data. Buyer expenditure records what eligible English buying units paid for the defined service in a stated period. Supplier revenue records net consideration recognised for that service. Adoption counts eligible buyers with a verified qualifying transaction. Gross payment flow, revenue, spend and adoption cannot be added or substituted for one another.

Use official business data only as a frame

The ONS 2025 business activity dataset provides counts of enterprises and local units by industry, size and geography from the Inter-Departmental Business Register. It can support a stratified sample of registered English organisations. No SIC code identifies UGC marketplace buyers or suppliers.

The ONS quality and methodology page says the register principally covers VAT or PAYE based enterprises and generally locates an enterprise at its head office or main operating site. Unregistered activity can be absent, while a registered English address does not prove that a commission, creator, publication or audience was in England.

Companies House's company information service can confirm filed details for a named incorporated supplier. It does not verify a marketplace product, trading status, transaction value or service geography. Supplier websites are claims unless supported by contracts, invoices or structured responses.

Run two compatible studies

For buyers, define eligibility as an organisational unit with an English workplace that authorised a qualifying commission during the study window. Draw the sample before asking about use. Require a respondent able to inspect contracts and payments. Record sampled, invited, screened, eligible, responding and usable cases, along with missing invoice fields and contradictions.

For suppliers, identify legal entities through declared, reproducible routes. Screen each against the same service definition. Ask for eligible transaction count and net revenue, with creator consideration, media, tax and refunds separated. Record non-response and group relationships so the same contract is not counted through an operator, reseller and agency.

HMRC's seller guidance for digital platforms describes information that some operators collect and report about sellers and consideration. That record can shape evidence requests. It is not a public list of UGC creators, does not prove that a particular service is in scope and does not measure England's market.

Publish the boundary, not a false total

Report captured buyer expenditure or supplier revenue only for the observed frame. Any weighting needs declared strata, non-response treatment, uncertainty and a named UK statistician. Publish exclusions for unregistered suppliers, overseas contracts, missing allocations and bundled services.

The answer may remain "no defensible estimate" if compatible evidence is unavailable. That is more useful than multiplying broad business counts by an assumed adoption rate. Publication also needs qualified accounting, tax and contract review of the chosen revenue, payment and geography definitions.

What to collect next

Prepare a data dictionary, eligibility screener, invoice abstraction form and duplicate-entity rule. Test them on fictional records. Proceed to permissioned fieldwork only after sampling, privacy, commercial-confidentiality and statistical review. Until the resulting coverage and inference are defensible, the England total stays blank.

Before you act

Common questions

Why can't I use ONS business counts to estimate the UGC marketplace total?

The ONS dataset provides counts of enterprises and local units by industry, size and geography. No SIC code identifies UGC marketplace buyers or suppliers. It can support a stratified sample but does not measure eligible marketplace transactions. Unregistered activity can be absent, and a registered English address does not prove the commission was in England.

What should I do if compatible evidence for a market total is unavailable?

The answer may remain no defensible estimate. That is more useful than multiplying broad business counts by an assumed adoption rate. Report captured buyer expenditure or supplier revenue only for the observed frame. Publish exclusions for unregistered suppliers, overseas contracts, missing allocations and bundled services.

How do I avoid counting the same contract through an operator, reseller and agency?

Record non-response and group relationships so the same contract is not counted through an operator, reseller and agency. For suppliers, identify legal entities through declared, reproducible routes and screen each against the same service definition. Ask for eligible transaction count and net revenue with creator consideration, media, tax and refunds separated.
