Revenue not disclosed

Computer Security Technology Ltd.’s accounts for the year to 31 Dec 2024 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.

Employees: 8
Net assets: £770k

Indirect — not revenue

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.

Net assets: ▼14%; Now £770k
Cash at bank: ▼4%; Now £462k
Headcount: 0%; Now 8
Deferred income: ▲49%; Now £43.7k
Fixed assets: ▼25%; Now £307k

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