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: ▼34%; Now £3.1m
Cash at bank: ▼12%; Now £883k
Headcount: ▼4%; Now 67
Deferred income: ▲4%; Now £7.2m
Fixed assets: ▼11%; Now £151k

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