Key figures

Revenue not disclosed

S.i.r.s. Navigation Limited’s accounts for the year to 31 Mar 2025 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 profit & loss account — 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.

Balance-sheet signals

Year-on-year changes in filed balance-sheet items. They can hint at momentum (or investment) but are not revenue or profit and must not be read as such.

Deferred income is reported together with accruals in this filing (“accruals and deferred income”), so it is an approximate signal only.
