Clinics with an actual Companies House filed turnover only — ranked highest to lowest, with a cumulative concentration (Lorenz) curve.
Read me: filed turnover is reported per legal entity, so a chain files one figure covering all its sites — those are tagged company · N sites. Single-site entities are single clinic. Most aesthetic clinics are micro-entities that legally omit turnover, so this is a small, self-selected subset — not the whole market. Default view = aesthetic-medicine segments only (beauty/facial studios held out).
