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: ▲2%; Now £54.7m
Cash at bank: ▼42%; Now £14m
Headcount: 0%; Now 40
Deferred income: ▲109%; Now £51.2k
Fixed assets: ▲0%; Now £10m

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