As well as the information available from the NHS 111 service, the Local Authority has information, advice on local services and support on their COVID 19 webpage  here  including a section on "How to ask for help":

If you are in need of help, and are not sure who to talk to, there are three ways to get in touch. 

1. If you or someone you know needs this support, please fill in our request support form and we will contact you. You can complete the form at any time.
2. If you need support from a charity in Sutton, email Community Action Sutton at enquiries@communityactionsutton.org.uk, they’ll forward you the right charity. 
3. Call us at 020 8770 5000, option 6. If you are an extremely vulnerable person, please call us in the first instance so we can provide immediate support.
