UK business population by SIC code: where the official counts live

Datadory catalogs 15 datasets for Specialized Consumer Services - zero primary records and 15 pooled from adjacent industries - and the UK business-population question routes through one of them: UK Business Register and Employment Survey (BRES) — UK Business; Activity, Size and Location. The Office for National Statistics builds it from a point-in-time extract of the Inter-Departmental Business Register, the register of UK businesses recorded with HM Revenue and Customs for VAT and/or Pay As You Earn.

The 2025 edition works from a snapshot taken 14 March 2025. It reports 2.73 million VAT and/or PAYE based businesses, up 0.4% year on year, and 3.2 million local units, up 0.2%, tabulated across 28 numbered tables of 414+ rows each.

Editions reach back to 1994 in Datadory's catalog, with pre-2017 vintages published as separately numbered table files rather than a single consolidated release. Datadory scores it 9 out of 10, the joint-highest mark in this industry's pool.

The published tables break counts down at two depths: broad industry group and 4-digit UK SIC 2007 class. In the services territory closest to this industry that means section rows such as 81 : Services to buildings and landscape activities sitting above classes like 8010 Private security activities, 8110 Combined facilities support activities, 8121 General cleaning of buildings, 8130 Landscape service activities, 8220 Activities of call centres and 8230 Organisation of conventions and trade shows. If you need the definition behind a code before you query it, the SIC 2007 classification glossary entry unpacks the hierarchy.

Go one digit deeper through NOMIS - UK Business Register & Employment Survey by SIC, the service Durham University runs for ONS. Its BRES tabulation dimensions industry to five-digit subclass and resolves roughly 1,171 SIC industries across hundreds of geographies per year.

Each SIC figure carries five companion dimensions: geography written as ONS GSS code plus name (E12000007 : London, for instance) down to countries, English regions, counties, districts and unitary authorities and parliamentary constituencies; employment size band; turnover size band in thousands of pounds; and legal status spanning companies, sole proprietors, partnerships, public corporations, central government, local authorities and non-profit bodies. One caveat travels with every cell: figures are disclosure-controlled and rounded to base 5, so a class showing 165 enterprises in the North East is accurate only to the nearest five.

Three personas pull hardest on this dataset. Market-entry analysts use class-by-region counts as the denominator for share and penetration models; commercial real-estate teams read local-unit density by district and parliamentary constituency as a siting signal; lenders and investors screen a sector's size-band and legal-status mix before underwriting a portfolio.

A worked example shows the grain available. England counted 43,000 employees in SIC 63110 Data processing, hosting and related activities for 2024 - 0.2% of the English workforce - of whom 39,000 were full-time. The same year's enterprise count for that class stood at 2,960. Jobs and businesses move on separate axes, so pairing the two is what turns a raw count into a market picture.

Because every figure carries five companion dimensions - geography down to constituency, employment size band, turnover size band and seven legal statuses - the same tables answer 'how many', 'how big' and 'what kind' without ever leaving the dataset.

Reading the 2025 edition is a matter of crossing a class row with the geography column you need. Three classes from the 80-82 support-services belt show how the same count narrows as geography tightens:

Cleaning dominates that belt at every level of geography - 13,545 enterprises UK-wide for SIC 8121 General cleaning of buildings, roughly double private security's 6,980 - and the spread between UK and North East columns repeats across all three classes, because the same table set reprints each count for Great Britain, England and Wales, England and every region.

Enterprise counts answer how many businesses exist, not how many people they employ or where their sites sit. For jobs by SIC code, NM_189_1 adds an EMPLOYMENT_STATUS dimension splitting employees from full-time employees; for sites, the 3.2 million local units answer separately from the 2.73 million enterprises. When the question turns to births and deaths of businesses rather than the standing population, ONS publishes Business Demography alongside it.

Datadory delivers UK business-population data covering enterprises and local units by 4-digit UK SIC 2007 class, region, size band and legal status - delivered daily, weekly, or hourly, your call. Ask a sample request for the 81-support-belt rows, the North East columns or the sole-proprietor split and you get exactly those cells to test against your model.

Two caveats travel with the numbers through any channel. Figures are disclosure-controlled and rounded to base 5, so gaps smaller than ten between neighbouring cells are noise rather than signal. And confidential-flagged cells carry restrictions on onward sharing, consistent with the register's promise never to expose any specifically identified business.

That discipline is what makes register-based counts such a durable base layer for sizing a services market: the numbers reconcile across tables, regions and years because every one of them descends from the same point-in-time snapshot extract.

The UK's SIC 2007 is a national variant, so cross-border sizing means switching frameworks as well as sources. The American counterpart is NAICS. U.S. Census Bureau Data API - CBP / Economic Census / Wholesale Trade serves 1,798 catalogued datasets in JSON, JSONP or XML, including County Business Patterns annually from 1986 to 2023, reporting establishments, employment and payroll by NAICS code down to ZIP-code detail; the latest vintage, reference year 2023, was published 26 June 2025. Point-and-click analysts can reach overlapping tables through Census Data Tables & data.census.gov through ready-made tables of the same establishment counts.

Five-yearly depth comes from the Economic Census, the official measure representing over eight million business locations across nearly 21,000 geographic areas; its wholesale-trade sector 42 basic table alone runs to 442,035 rows. On the continental side, Eurostat - European Statistical Office Data Portal publishes monthly indicator series for 41 European geographies back to January 1991, organised by NACE class rather than SIC.

Treat the three as complements with one discipline: never sum counts across frameworks. An establishment in County Business Patterns, an enterprise in BRES and a local unit are different statistical animals, and mixing them quietly inflates any market-size model.

The specialized-consumer-services data guide is the pillar for this slice: it maps all 15 pooled records with the coverage, format and quality-score fields behind every source named above. When the UK register question turns into a venues question, salon barbershop spa marketplace data covers the listing side of the same market.

Two sibling clusters extend the counting exercise westward and eastward: census data api county business patterns walks the American establishment counts, and european retail and services statistics works Eurostat's monthly NACE series country by country.

Shortlists live on the industry pages too - the free specialized-consumer-services datasets list and the best specialized-consumer-services datasets roundup both index the records named above. All 15 are catalogued with coverage and quality fields in the specialized-consumer-services data hub.
