During the unprecedented hot weather, South East Water are asking customers to only use water for essential use to ensure supplies for everyone.
If you are a vulnerable customer (e.g. OAP, pregnant or have children under 5, have a medical condition, learning difficulties or are disabled) you can sign up for free to the Priority Services Register (PSR) so you will receive additional support in the event that your supply is interrupted. Each utility service (Gas, Water, Electric) hold a PRS register, so you would need to sign up to them all so you receive the help when needed.
If you are a South East Water customer you can sign up for their PRS here https://www.southeastwater.co.uk/help/priority-services/register-for-priority-services
