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: ▲24%; Now £976k
Cash at bank: —; Now —
Headcount: ▲5%; Now 20
Deferred income: ▲290%; Now £985k
Fixed assets: ▲36%; Now £18.9k

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