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: ▲22%; Now £2.1m
Cash at bank: ▼5%; Now £871k
Headcount: ▼3%; Now 32
Deferred income: ▲8%; Now £364k
Fixed assets: ▲115%; Now £461k

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