Eligibility and coverage are checked again before a provider can submit an estimate

Suitable for one accessible domestic toilet with a common cistern fault such as continuous running, weak or failed flushing, slow refilling, or a minor leak at the cistern fittings.
The plumber diagnoses the fault, repairs or replaces one suitable common cistern mechanism or seal from available standard stock, adjusts the mechanism, and performs repeated flush and leak checks.
Scope boundaries: The fixed scope assumes a standard accessible cistern and sound toilet pan, water connection, isolation valve, and waste connection. Pan removal, concealed or proprietary systems, drainage blockages, and leaks outside the cistern mechanism need a separate scope.
No fixed provider price or appointment is published here. Eligible providers define the work, milestones, price and timing in an estimate; Serproz adds no customer platform fee, and the customer chooses whether to accept it.
Only a claimed provider who passes the applicable verification and exact-job capability checks can submit an estimate. Nothing is charged when you post; after acceptance, review the provider's recorded job price before funding the agreed milestones.

Quote basis
This page does not publish a fixed provider offer. Each eligible provider estimate must state the proposed scope, milestones, price and timing before the customer chooses one.
What to confirm before you request
- Is the cistern visible and accessible, concealed in a wall, or part of a wall-hung system?
- Is the problem continuous running, poor flushing, failed refilling, a damaged control, or a visible leak?
- Where exactly is water appearing, and is wastewater overflowing?
- Can the toilet's water supply be isolated with a working accessible valve?
- Can you share the make, model, or a photo of the cistern and internal mechanism?
