A new charitable organisation has been launched called the Council of British Hajis:

The CBH is a not-for-profit voluntary charity whose aims are to work for the welfare of British Hajjis and to ensure that they are relieved of any distress and to ensure that Hajj service providers perform their obligations towards the pilgrims making the experience an enjoyable one.
