Typical simple repair range
Current UK market guidance puts a typical leak-repair range around £77–£128 and an average near £100, while burst-pipe repair examples can rise to around £150 or more depending on the work.
Hidden costs are often access costs
A cheap fitting can still become an expensive job if the plumber has to locate the leak, lift flooring, remove boxing or open a wall before reaching it.
For active leaks
• Shut off the water if safe and practical.
• Protect electrics from water and seek urgent help where needed.
• Photograph damage for your records.
• Ask what repair and making-good are included.
