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: ▲12%; Now £6.4m
Cash at bank: ▲45%; Now £825k
Headcount: ▼3%; Now 63
Deferred income: ▲23%; Now £596k
Fixed assets: ▼12%; Now £1.1m

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