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 −£2.6m
Cash at bank: ▼63%; Now £402k
Headcount: ▼29%; Now 22
Deferred income: ▲41%; Now £1.1m
Fixed assets: ▼85%; Now £1.2k

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