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: ▼117%; Now −£1.5m
Cash at bank: ▼14%; Now £1.8m
Headcount: ▼10%; Now 283
Deferred income: ▲3%; Now £5.5m
Fixed assets: ▲21%; Now £284k

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