How this is counted
Every company incorporated in the UK is taken from the Companies House public register the day after it appears and placed 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.
