Plumbing problems in the bathroom are one of the most frustrating issues faced by Londoners — whether you’re a homeowner, tenant, landlord, or property manager. From constant dripping taps and low water pressure to blocked drains and leaky toilets, these problems can quickly turn from a minor inconvenience into a major repair job.
In London, where many homes are decades old and hard water is common, bathroom plumbing issues tend to happen more often than you’d expect. Over time, limescale buildup, rusted pipes, or worn-out parts can affect the performance of your plumbing system — leading to water waste, higher bills, and potential damage to your property.
But don’t worry — this blog is here to help. We’ve put together a simple and practical guide covering the 15 most common bathroom plumbing problems in London, along with easy-to-understand solutions and what exactly needs changing to fix each issue.
