Thank you for raising this question. I’m sure that this is something that lots of people in your position worry about. You could talk to your brother’s social worker about what would happen if things need to change. Your brother’s care and support is normally the responsibility of the local council. They have a duty to meet his ‘eligible needs’, and so adult social care would normally be involved if a move was needed, unless your brother’s care is funded by health. The government says that local authorities should plan for this, “by ensuring that any potential emergency needs are identified as part of the care and support planning stage and planned for accordingly.”
Please note that, if your brother has substantial difficulty taking part in the care and support planning process, he would be entitled to have a family member, friend – you don’t have to have a formal legal status for this - or advocate to support him.
Here are some links to resources you might find useful:
Chapter three at the following link suggest ways that people can build up a network of friends and relationships, so that they are not always reliant on one person: https://www.mentalhealth.org.uk/learning-disabilities/our-work/family-friends-community/thinking-ahead. You might also find chapter six of this download useful, as it looks at the different types of housing that people with a learning disability might live in.
There will be some people with a learning disability who do not have a full enough understanding of the issues to make a major decision about moving home. In these cases, the decision needs to be made in their ‘best interests’. In this case, you should always be involved in such a decision, and the following link includes template letters to challenge such decisions if you haven’t been consulted: http://www.irwinmitchell.com/activities/best-interest-decisions-tool.
If you wanted to talk to your brother about what would be important to him in the future if he did need to move from his current home, you might find some of the ‘person-centred planning’ tools on the following site useful: http://helensandersonassociates.co.uk/person-centred-practice/.
With best wishes,
