Methodology
How this ranking was built
Ekorrar identified active UK advertising agencies, media representation and public relations companies with filed annual accounts and ranked them by latest reported revenue.
Companies were excluded when they were inactive, outside the selected advertising industry labels, below GBP 1,000,000 latest revenue, or had unusable numeric values.
The data comes from official public registry and filing sources, including Companies House and filed annual accounts.
Data accuracy note
Ekorrar uses official public sources and normalized registry/financial data, but public filings can be delayed, incomplete, amended, inconsistently classified, or affected by extraction and normalization errors. Rankings are market-intelligence signals, not financial, legal, investment, credit, or procurement advice.
