Which Swansea districts are covered for leak detection?
Leak detection covers Swansea. The office team arranges visits and reports.
Swansea City Centre, Hafod, Landore and the Maritime Quarter use SA1. The Quadrant Shopping Centre adjoins Swansea Market, giving town-centre enquiries a useful landmark alongside the street name. For a shop or flat, identify the entrance that reaches the affected room.
- City Centre SA1
- Hafod SA1
- Landore SA1
- Maritime Quarter SA1
- Port Tennant SA1
Swansea’s SA2 localities include Brynmill, Sketty, Uplands, Killay and Dunvant. The conservation-area review records nineteenth-century houses in Ffynone and houses divided into multiple occupation. At a converted building, explain which rooms and shared spaces can be entered before a leak visit is arranged.

- Uplands SA2
- Killay SA2

Mumbles, Oystermouth and West Cross appear in the SA3 postcode district. For a water leak around this part of Swansea Bay, give the locality as well as the outward code so the affected property is clear.
- Mumbles SA3
