Each city figure carries a confidence label. It tells you how much data sits behind the number.
They tell you how much data is behind a figure (as of Nov 2026).
Robust means at least 30 buildings and 100 quoted desk rates.
Indicative means 10 to 29 buildings and at least 30 rates. Treat an Indicative figure as a guide rather than a benchmark.
Below that we don't publish a median. We show only the count with the lowest and highest rates.
The same rule applies when we break a city down by office size or area. So a small area or size band may show no median even when its city does.
Check the label before you quote or compare a figure.
