Indirect — not revenue

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: ▼72%; Now £718k
Cash at bank: ▲16%; Now £1.2m
Headcount: 0%; Now 3
Deferred income: ▲134%; Now £587k
Fixed assets: ▼6%; Now £8.5m

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