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: ▲36%; Now £1.8m
Cash at bank: ▲113%; Now £212k
Headcount: ▼8%; Now 418
Deferred income: ▼4%; Now £973k
Fixed assets: ▲5%; Now £409k

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