Shelter is a registered charity that provides housing advice, support, and campaigns to end homelessness in England, Scotland, Wales, and Northern Ireland. It was founded in 1966 in response to overcrowded housing conditions and helps millions of people annually who are struggling with housing or homelessness. While Shelter has achieved successes such as influencing legislation protecting tenants and the homeless, it continues to campaign for more affordable housing and to help the estimated 100,000 homeless children in the UK. Shelter relies on support from partners and donors to fund its services to those in need of housing assistance.
