In an emergency
If there is any threat to life you should always call 999. The app ‘what three words’ is handy to have on your phone as it can tell an emergency service exactly where you are: https://what3words.com/products/what3words-app
If the situation is not life threatening, but due to something like extreme weather, the emergency numbers to contact are in the Water, Electricity and Gas sections.
It is strongly recommended to register with the Priority Services Register (PSR). This is a free UK service that covers gas, electricity and water supplies. It means you receive advance notice of power or water cuts, and if there is an emergency you are treated as a priority to be reconnected and also given access to alternative heating and cooking facilities. There is a range of criteria to register, but it applies if you have a child under age 5, use medical equipment reliant on electricity or water, have a disability or chronic illness, or have anxiety, depression or any mental health condition.

You should register directly with your gas, electricity and water suppliers.
