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.

Cash at bank: ▲74%; Now £1.1m
Headcount: 0%; Now 3
Deferred income: ▲17%; Now £92k
Fixed assets: ▼4%; Now £6.6m

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