Most likely cause & what to check
A standard close-coupled toilet supply and installation costs £150–£350. The toilet unit itself costs £80–£300 (budget to mid-range); labour to swap like-for-like is typically £80–£150. Close-coupled toilets are the simplest to fit — cistern sits on top of the pan.
Back-to-wall toilets (pan against the wall, cistern hidden in a frame or furniture unit) cost more to supply (£200–£600 for the unit) and more to install (£150–£300 labour) due to the frame build. Allow £400–£800+ in total.
Wall-hung toilets cost the most: the unit is £300–£800+, the concealed frame and cistern is £100–£200, and installation is £200–£400 due to the structural fixings and plastering involved. Total: £600–£1,400.
If you are only replacing the toilet pan and keeping the existing pipework, the job is straightforward. If soil pipe connections need moving or new waste connections are required, budget extra for the pipework.
Disposal of the old toilet: most plumbers will take it away for a small additional charge (£20–£50), or you can put it in a skip or take it to a household waste centre.
