Service Activities Incidental To Water Transportation

Details for Service Activities Incidental To Water Transportation

SIC code 52220 is used for businesses carrying out activity in the field of service activities incidental to water transportation. In plain English, it is likely to include clinics, care providers, healthcare professionals, therapy businesses, support organisations and wellbeing services, with day-to-day activity often involving patient services, treatment, care coordination, clinical administration, appointments and regulated support. As of June 2026, 52220 ranks 386th out of 731 five-digit SIC codes, with 1,536 UK companies registered under it, making it a mid-tier classification used by a focused group of companies.

This sits within a classification system that has been used in the UK since the 1940s; Companies House filings moved from 4-digit SIC 2003 codes to the current 5-digit SIC 2007 scheme in 2008–2009, bringing the UK register into line with NACE Rev. 2. Because a UK company may register up to four SIC codes at Companies House, a business can pair this activity with other relevant codes where its operations span several markets or revenue streams.

The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as service activities incidental to water transportation services, specialist service activities incidental to water transportation providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. In practical terms, the code helps separate this kind of work from neighbouring sectors that may look similar in search results but involve different trading models, assets, customers or regulatory expectations. It is also useful for analysts, lenders, marketers and public bodies because it gives a consistent way to group companies by declared activity, even though the description is not a licence, approval or guarantee of what a company actually does day to day.

A company using this code might be newly incorporated, dormant, small and owner-managed, or part of a larger group, so the SIC entry should normally be read alongside accounts, confirmation statements, websites and other commercial signals. The classification is especially valuable when comparing suppliers, prospecting for customers, segmenting a database, reviewing competition or checking how a company presents its principal line of business on the public record.
