Transitional Housing Benefit. Prior to April 2003, THB was the 'vehicle' to calculate the costs of the support. It was introduced in April 2000 to allow the true costs of support to be identified and funded via Housing Benefit and introduced a new category of cost to Housing Benefit, General Counselling and Support. This system ended on March 31st 2003 and in April 2003 it reverted back to Housing Benefit, which now only covers rent and housing management costs. The support element was then transferred to the 'pot' which will be used to pay for the costs of housing related support.
