Using these figures

Free to use in a newsletter, on a website, in a report or at an event, with attribution to Salenovo and Companies House. A ready-made line:

A different cut (a sector, a month-by-month series, these councils beside their neighbours) is usually a same-day reply: hello@salenovo.com.

How this is counted

We take every company incorporated in the UK from the Companies House public register the day after it appears and place it in a council by its registered-office postcode (ONS Postcode Directory). The figures here are the council pages' own, added together. "Own address" leaves out registrations at addresses that take 100 or more a year (formation agents and virtual offices), because those say where the agent is, not where the business is. "Expected to trade" is the historical trading rate of similar companies, summed: an estimate for the area, not a judgement on any company. The official ONS business demography arrives about fifteen months after the fact; this is the same register, counted weekly. Method and accuracy.
