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: ▲12%; Now £12.9m
Cash at bank: ▲46%; Now £6.4m
Headcount: ▼3%; Now 211
Deferred income: ▲36%; Now £1.3m
Fixed assets: ▼4%; Now £4.9m

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