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: ▲2%; Now £2.2m
Cash at bank: ▼24%; Now £2.4m
Headcount: ▼4%; Now 49
Deferred income: ▲72%; Now £2.9m
Fixed assets: ▲68%; Now £133k

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