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: —; Now −£1.3m
Cash at bank: ▲131%; Now £1.5m
Headcount: ▲16%; Now 66
Deferred income: ▲19%; Now £7.4m
Fixed assets: ▼43%; Now £199k

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