Knowing where utility controls are can be useful before an incident. During flooding, access and electrical hazards may make ordinary actions unsafe, so a plan must include when to stop and seek professional help.

Learn in settled conditions
Ask the landlord or a competent professional to identify the correct gas, water and electrical controls and explain any relevant instructions. Record their locations in the household plan. Do not practise by disconnecting essential care equipment or opening electrical enclosures. Anyone expected to act must understand both the task and its limits.
- Keep provider emergency numbers on paper.
- Make access routes clear before bad weather.
Never enter water to reach controls
Official guidance advises shutting supplies only if safe. Do not touch electrical switches, appliances or plugs while standing in floodwater, and do not assume an outage means every circuit is safe. If controls are inaccessible or affected, leave them and tell the appropriate service about the hazard from a safe place.
- Keep other people away from the area.
- Do not attempt improvised electrical isolation.
Treat restoration as a separate decision
After flooding, do not turn supplies or affected equipment back on simply because the water has gone. Follow utility-company and qualified engineer advice about inspection and recommissioning. Record the checks and instructions for other household members so nobody unknowingly restores an unsafe appliance or system.
- Tell contractors where flooding reached.
- Follow evacuation instructions without delaying for switches.
