Blocked toilet in Southwark? If it's the pan or the internal waste, that's us. If the blockage is in the external drains, you'll want our drainage partner — and we'll tell you honestly which it is on the phone.

Southwark water notes: Southwark shares the capital's hard water, and scale shows up early in the borough's hard-worked conversions and new-build blocks alike — descaling and inhibitor fits are routine here. Southwark runs from Peckham and Camberwell terraces through big post-war estates to the dense new stock of Elephant & Castle and Bermondsey — with communal systems and boosted supplies common in the newer blocks. Mains supply here is managed by Thames Water.

Faults we fix in one visit

The everyday list in Southwark: fill valves that no longer shut off, flush seals letting water trickle into the pan (the classic cause of a moving meter), siphons that have lost their diaphragm, leaking close-couple kits between cistern and pan, failed pan connectors at the base, and blocked pans or internal branch pipes. All standard, all fixable same-visit with stocked parts.

Blocked toilet: internal vs external

If the blockage sits in the pan, the trap or the internal soil branch, we clear it mechanically — no drain-destroying chemicals. If other fixtures are backing up too, or the problem is downstream in the external run or a shared stack, the blockage is a drainage job. We'll diagnose honestly and hand you to our drainage partner rather than charging you for the wrong trade.

Running toilets waste real money

A steadily leaking flush valve can pass 200–400 litres a day. On a metered Southwark supply, that's water and sewerage charges silently added to every bill, and on any supply it's an eventual overflow or damp problem. The dye test takes two minutes: a drop of food colouring in the cistern, wait fifteen minutes without flushing — colour in the pan means the flush seal is passing and needs replacing.

Cost of toilet repair in Southwark

Most standard repairs — a fill valve, flush valve, or internal unblock — fall in a from-£89 band in Southwark including the part, agreed before work starts. Concealed cisterns and macerator faults are quoted after inspection because access varies. No fault is invented to lift the invoice; if the honest fix is a £15 part, that's what gets fitted.

Frequently asked questions

Should I repair or replace my toilet?

If the pan and cistern are sound, repair — internals are cheap and universal. Replace when the pan is cracked, the suite is obsolete enough that spares are unavailable, or repeated repairs are chasing a fundamentally worn unit. You'll get a straight recommendation either way.

Can you unblock a toilet without chemicals?

Yes — and we'd rather. Mechanical clearing with a closet auger removes the blockage instead of dissolving a hole through it, and caustic chemicals make later work hazardous. If chemicals have been used, tell the engineer before they start.

My toilet leaks at the base — is that serious?

Yes: base leaks are usually a failed pan connector or a broken seal on the soil connection, meaning foul water into the floor. Stop using it where possible and get it reseated — the repair is routine, the untreated damage isn't.

Why does my toilet keep running?

Two usual suspects: a fill valve that no longer shuts off cleanly, or a flush valve/siphon seal letting water pass from cistern to pan. Both are inexpensive stocked parts. The food-colouring dye test tells you which within fifteen minutes.
