Source-of-truth, not re-licensed
We pull directly from the Companies House submission stream, typically within ~3.4 minutes of each filing. Bureaus re-license curated extracts on a quarterly cycle — they're months behind a fresh print.
Birmingham's 2026 sample of 88 active filers reports £2.7M average revenue. Operating margin is not yet reportable in the current data window, full margin readings await FY25 filing closure across the sample.
Companies House publishes the filings. We parse them — every iXBRL submission, every business day, against 41 named stability checks. The numbers on this page reflect the live UK population, not the curated extract that bureaus re-license a quarter behind.

This is the 2026 financial-stability snapshot for Birmingham. The current active sample contains 88 filers averaging £2.7M of revenue. The operating-margin figure is not yet reportable because a meaningful share of the sample has filed under abridged accounts (FRS 105) for the current FY, leaving the margin denominator partially undisclosed across enough of the population to suppress a defensible regional aggregate.
Margin will populate as the remainder of the sample lands full-form FY25 filings. Subscribers to the daily Pulse feed will see the figure populate automatically as the iXBRL tags arrive.
Birmingham’s sample is disproportionately weighted toward FRS 105 abridged filers in the current window — a structural feature of the regional mix rather than a one-off cycle quirk. The most informative early signals to monitor will be:
