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: ▲25%; Now £3.3m
Cash at bank: ▼14%; Now £271k
Headcount: ▼12%; Now 22
Deferred income: ▲108%; Now £1.7m
Fixed assets: ▼6%; Now £8.4m

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