    Companies can hold more than one SIC code, so per-code counts can add up to more than the directory total. The website percentage shows how many companies in each code have website details on file.

    Sources & assumptions

    Sources

    • •Company records imported from the Companies House public register and refreshed on a rolling schedule.
    • •Websites, logos and profile extras added by company owners or the Construct365 editorial team.

    Assumptions & exclusions

    • •Coverage grows continuously; a firm missing today may simply not have been imported yet.
    • •Owner-supplied details are checked against Companies House where possible but are not independently audited.
