Process and cost factors
First fix in a bathroom: what it actually covers
What drives the timeline
- Pipework for hot, cold and waste is run to
- the agreed fitting positions, pressure-tested, and left capped off ready for boarding.
- Electrical cabling for lights
- extraction, shaver points and any underfloor heating mat is laid and chased in before plastering or boarding.
- Stud walls or false walls for concealed cisterns are built at this stage
- along with any noggins needed to support future grab rails or heavy fittings.
- This is the point at which moving a tap or
- socket position is straightforward; after boarding it becomes far more disruptive.

Your questions answered
Can I change the layout once first fix is done?
Only with extra work, since pipework and cabling are already routed to fixed points, changes now usually mean opening the wall back up.
Is first fix inspected before it's covered up?
It should be, either by the fitter checking their own pressure tests or by an electrician certifying the circuit, before boarding hides the work.
Rather speak to someone than fill in a form?
Ring during the working day and you will get an answer from the person who would be on site, not a call centre.
