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: ▲8%; Now £6.7m
Cash at bank: ▲5%; Now £5.6m
Headcount: 0%; Now 56
Deferred income: ▲18%; Now £131k
Fixed assets: ▼3%; Now £1.2m

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