The UN Refugee Agency, UNHRC helps accommodating refugees in tents, and camps.
Here is the list of contact numbers of relevant departments.
IMPORTANT NOTE: When asylum seekers receive their leave to remain in the UK they are often given just 28 days to vacate their Home Office accommodation and find somewhere else to live. They get no preferential treatment regarding the allocation of social housing and have to join housing waiting lists like everybody else. However, the notice period is almost always too short for them to find alternative housing, so they inevitably have to suffer a period of homelessness. Many of them may have only been in the UK for a couple of months and therefore have no friends, little knowledge of the English language and no money to support themselves. Life on the streets is dangerous, especially for women, and makes it impossible for refugees to work and get established in the community.
