Shower Repair London — Same-Day, Gas Safe

A shower that's dripping, running hot-then-cold, or barely trickling out is telling you something specific is wrong inside the valve or head — here's what each symptom usually means.

• Water dripping from the shower head or spout after you turn it off
• The handle is stiff, loose, or won't hold a set temperature
• Temperature swings between hot and cold mid-shower
• Weak or trickling flow that's got noticeably worse over time
• Water leaking from behind the tiles, or a stain appearing on the ceiling below
• An electric shower unit that trips the electrics, won't heat, or won't switch on
• A diverter that won't switch cleanly between shower and bath taps

If you're dealing with a leaking shower specifically, our low water pressure guide and a look at the seal around the tray or screen are good first checks while you wait for an engineer.

We repair every part of the shower system, not just the handle you can see — most faults trace back to one of a handful of components.

• Mixer valve cartridges — the most common fix for drips and temperature faults
• Thermostatic cartridges that no longer regulate hot and cold correctly
• Diverter valves that stick or won't switch between outlets
• Shower heads, hoses and risers clogged with limescale
• Electric shower elements, thermal cut-outs and control units
• Low pressure caused by a partially closed isolation valve or blocked inlet
• Leaks at the shower tray, screen seal, or where the riser meets the wall

If the fault turns out to be with the silicone seal or the shower tray rather than the valve itself, that's a slightly different job — see shower resealing for that side of things.

Most London bookings for shower repair are seen the same day, and we're usually able to offer next-day for anywhere across Tower Hamlets, Hackney, Islington, Canary Wharf, Shoreditch, Whitechapel, Bethnal Green and Mile End. Being based centrally in E1 rather than dispatched from outside the city is what makes that turnaround realistic rather than a promise on a page.

If the shower is actively leaking into a ceiling or the flat below right now, call 07460 824073 rather than booking online — a fast response limits how much damage the leak does while it's running.

A mixer shower blends hot and cold water through a single cartridge, and that cartridge is almost always the first thing we check when a shower drips, won't hold temperature, or feels weak. Limescale is the biggest cause of both low pressure and cartridge failure in London specifically, because much of the city sits on hard water — it narrows the internal waterways inside the valve over a few years of normal use.

If the whole property has weak pressure — not just the shower — the cause is more likely the incoming supply, a shared stopcock, or a combi boiler flow rate issue rather than the shower valve itself. Our guide to low water pressure walks through how to tell which one you've got before booking a repair.

From replacing a failed thermostatic cartridge in Bethnal Green to sorting a leaking mixer valve in Canary Wharf, RenoPlumb repairs showers across East and Central London every week. See more examples on our Our Work page.

It depends on the part that's failed — a cartridge, a diverter, an electric element or a full valve are all different jobs — so we always confirm with a free, no-obligation quote once we've seen the fault rather than guessing over the phone. See our pricing page for more detail on how we cost jobs.

We fix leaking and broken showers across East and Central London, including for a plumber in Hackney, a plumber in Southwark and a plumber in Newham. See our area pages for borough-specific coverage.
