UK Regional Directory
How companies in London, Manchester, Edinburgh, Belfast and Birmingham are performing, from 418 active filers re-aggregated every business day. London is the benchmark the others are measured against.
Side by side
Two measures, so two charts. London, the benchmark, is in red.
Birmingham's margin is not yet reportable: too many companies there file shortened accounts that leave profit out.
5 regions monitored
London leads the 2026 UK regional sample with 113 active filers, £9.6M average revenue and a 23.31% average operating margin — the strongest combination of scale and profitability in the directory, and the de-facto national benchmark against which other regions are compared.
Read the London report ›Manchester's 2026 sample posts a 0.86% average operating margin against £1.7M average revenue across 119 active filers — a margin roughly 27× below the London benchmark and the steepest compression in the regional directory.
Read the Manchester report ›Edinburgh's 2026 sample posts a 1.77% average operating margin against £5.3M average revenue, a striking gap given the regional revenue base. Sample size of 72 firms warrants caution, but the margin compression is large enough to flag.
Read the Edinburgh report ›Belfast posts the highest average revenue per firm in the 2026 directory (£14.7M across 26 active filers) at a 6.05% operating margin, small sample but profitable, and meaningfully above the regional pack outside London.
Read the Belfast report ›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.
