What the symptom may mean
The timing can be revealing: a change after bathing, heating or rain points towards different questions. Access above the stain may be needed to investigate properly.

Use the information you already have. You do not need to investigate the pipework yourself, collect a special set of readings or choose equipment before contacting us.
Keep clear of bulging plaster or water near electrical fittings and seek urgent help where needed.

The relevant service to explore is Ceiling leak detection.
