Pass-through vehicle. This looks like a holding, staffing or umbrella company. Its revenue and profit may largely pass through to or from other entities, so the figures may not reflect a standalone operating business. It is excluded from our opportunity lists.

Unusual figures. Profit is higher than revenue in this filing. That usually means investment income, dividends from subsidiaries or one-off gains — or a mis-tagged figure. Check the original filing before drawing conclusions.

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: ▲3%; Now £4.4m
Cash at bank: —; Now —
Headcount: 0%; Now 2
Deferred income: ▼27%; Now £19.3k
Fixed assets: ▼1%; Now £7.9m

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