About this service
Installation work is quoted from the layout you describe. Share what is being connected, the room, and whether walls or cabinets need to be opened.
This page is for a new or replacement run that you already want, such as a tap point, a heater connection, or a pipe that has been agreed for replacement. It is not the page for an active leak that still needs finding.
Opening a wall or a cabinet is part of the description, not an assumption. If access is uncertain, say so and the reply will treat that as unknown.
