Key figures
Revenue not disclosed
Sos Leak Detection & Prevention Limited’s accounts for the year to 31 Mar 2026 contain a balance sheet but no profit & loss account, so its revenue and profit are not public. UK small and micro-entity companies are not required to publish a P&L — this is normal and says nothing about how the business is performing.
We never estimate revenue. Below you’ll find the balance-sheet figures that were filed — useful as indirect signals of momentum, but they are not revenue or profit.
