Firms showing no applications came from a trade body's own membership list; they may simply work outside the planning system. Contact details are the firm's own published ones. Decisions counted from 756 guernsey planning applications that name the agent. A rate is only shown once a firm has five decided applications — and a refusal is often a first draft, not a verdict on the firm.
