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: ▲137%; Now £1.9m
Cash at bank: ▲69%; Now £1.3m
Headcount: ▲13%; Now 27
Deferred income: ▲920%; Now £155k
Fixed assets: ▼12%; Now £380k

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