If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

An infrequently used fixture may lose its water seal over time, allowing odours through. Persistent smells after normal use can indicate another problem. Inspection should distinguish occasional lack of use from damaged or unsuitable drainage.

Before arranging the visit

Explain how often the room is used and whether the smell returns quickly.

Choosing the appropriate plumbing visit

We check the visible fault, isolation, pipe condition and access before agreeing the repair scope. Our waste pipes & traps page explains the related work and how an assessment is arranged.
