Corporate-structure complexity, scored from factors such as group structure, directors and shareholders. May be null when the structure section has not been computed.

• STANDARD — simple to moderate organisational structure.
• ELEVATED — complex organisational structure.
• HIGH — high to extreme complexity.
• UNAVAILABLE — complexity could not be determined (missing data or a calculation error).

Maturity stage, classified purely from the number of years since incorporation. May be null when the structure section has not been computed.

• YOUNG — less than 2 years since incorporation.
• EARLY_STAGE — 2–4 years since incorporation.
• ESTABLISHED — 4–10 years since incorporation.
• MATURE — 10 or more years since incorporation.

Size band, following UK Companies House (Companies Act 2006) thresholds. Taken from the most recent accounts filing type when it is decisive (e.g. micro-entity or small-company accounts); otherwise classified from financials using turnover when available, falling back to balance-sheet total assets (employee count is not used). May be null when the structure section has not been computed.

• MICRO — turnover ≤ £632k, or (no turnover) total assets ≤ £316k.
• SMALL — turnover ≤ £15M, or total assets ≤ £7.5M.
• MEDIUM — turnover ≤ £54M, or total assets ≤ £27M.
• LARGE — turnover above £54M (or total assets above £27M).
• UNAVAILABLE — no filing type or financial data is available to resolve a size band.
• LOADING — financial data is still being loaded; the size will be calculated once it arrives.

Whole number of years since incorporation, the same value the maturity band is derived from. Null when the maturity classification is unavailable.
