Most likely cause & what to check
The filling loop is the braided flexible hose under the boiler used to top up the pressure. Look at both ends — check whether the small valves (taps) are fully closed. If a valve handle is in line with the pipe, it's open and needs turning 90° to close.
If the hose itself is dripping or the valves won't close properly, this needs replacing — it's a simple job for a plumber.
Call a plumber. Tell them: "My boiler filling loop is leaking — I've checked the valves are closed but it's still dripping."
