What to Do Before the Plumber Arrives

Isolate the problem if it is safe: main stopcock for leaks and bursts; local appliance valves for toilets, washing machines and dishwashers; boiler power off for boiler faults (and National Gas 0800 111 999 if you smell gas). Open a cold tap after main isolation to drop pressure.

Clear a path to the stopcock, boiler, cylinder, loft hatch or affected bathroom. Move mats and small furniture. Keep children and pets out of wet areas. If you live in a mansion block or Chelsea Harbour apartment, arrange concierge or neighbour access and note any riser cupboards the building manages.

Photograph the leak, flood path, boiler display and any failed fittings. Note when the problem started and what you already tried. Have payment method and any insurance claim reference ready if this is an emergency make-safe for a claim.

Describe the issue clearly on the phone so we stock the van correctly — copper vs plastic, combi brand, toilet type, outdoor drain vs internal soil stack. Emergency Plumber Chelsea engineers arrive prepared for typical SW3 and SW10 housing stock, from period terraces to modern apartments.

Quick tips

• Put towels or a tray under active drips and empty bowls before they overflow.
• Do not dismantle boilers, gas fittings or sealed systems yourself.
• List building access codes or parking notes for the engineer — Chelsea streets can be tight.
• If a ceiling is bulging with water, catch drips below and avoid piercing it unless guided by a professional — sudden release can be heavy.
