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: ▼1%; Now £5.3m
Cash at bank: ▲453%; Now £492k
Headcount: ▼2%; Now 52
Deferred income: ▲1%; Now £281k
Fixed assets: ▼16%; Now £73k

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