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: ▲3%; Now £7.2m
Cash at bank: ▲33%; Now £1.4m
Headcount: ▼12%; Now 23
Deferred income: ▲98%; Now £447k
Fixed assets: ▼55%; Now £20.2k

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