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: ▲13%; Now £11.5m
Cash at bank: ▲18%; Now £3m
Headcount: ▼8%; Now 33
Deferred income: ▲130%; Now £1.1m
Fixed assets: ▲7%; Now £4.8m

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