Largest companies in Northolt by net assets

Ranked by net assets (total assets less total liabilities) in each company's latest accounts on file, for periods ending in the last 30 months, as at 11 October 2026. Net assets are not turnover and do not measure size of trade. Employees are shown where the accounts state an average number.

Only companies whose latest figures balance and pass our checks, in pounds and not dormant, are ranked, so this is the largest among those we can show reliably, not every company registered in Northolt. Figures are as filed with Companies House; CompanyStack does not audit them. A registered office is not always where a company trades.
