Carers UK is a national charity which campaigns for carers rights as well as providing useful information and advice. There are a number of resources that will help you:

Looking After Someone guide looks at the issues you might encounter as a carer. 

Upfront is an online tool that helps you to identify your statutory rights as a carer and any benefits and entitlements you might be able to access.

About Me is an e-learning resource which guides carers to find ways to support their own health and wellbeing.  The course is currently provided by Bedford Borough Council and can be accessed here 

The Jointly App aims to help family and friends who are sharing care easier by making communication and coordination simpler.  It allows appointments to be allocated, conversations to be summarised and medications & information to be stored in one easy-to-access place.

An online Carers Forum is available so you can access peer support 24/7.
