Emergency Stopcock Isolation

What emergency stopcock isolation covers

When time matters, the priority is to regain control of the mains water supply and prevent further damage.

• Rapid attendance to isolate the incoming water supply
• Locating internal and external stopcocks and isolating valves
• Dealing with seized, leaking, or broken valves where possible
• Isolation at the most appropriate point to protect the property
• Basic checks once isolated to confirm the water is fully off
• Clear explanation of what failed and what needs doing next

When this service is the right fit

Emergency stopcock isolation is most relevant when:

• You have active flooding or a fast-growing leak
• The stopcock is stuck, rounded off, leaking, or won’t fully close
• You cannot find the correct isolation point in the property
• A tenant, neighbour, or staff member reports water escaping and you need fast action
• You need to isolate water to a section of the building to reduce disruption

How the call-out is handled

You’ll be asked a few quick questions to understand what’s happening and what access is available. On arrival, the plumber will locate the best isolation point, shut off the supply, and confirm it is holding. Where safe and appropriate, temporary measures may be used to keep things stable until a permanent repair is completed.

After the water is isolated

Once the immediate risk is controlled, you’ll be advised on the next steps. This may include replacing the stopcock, fitting serviceable isolating valves, repairing the failed pipework or fitting, and checking for any ongoing leaks when the supply is reinstated. If you need it, you can also be guided on what information to record for a landlord, managing agent, or insurer.
