Subject to paragraph (2), where the benefit cap applies, the relevant authority must reduce the amount of housing benefit to which the claimant is entitled by virtue of section 130 of the Act by the amount by which the total amount of welfare benefits exceeds the relevant amount.

Where the reduction would reduce the claimant’s housing benefit to less than the minimum amount of housing benefit provided for in regulation 75 (minimum housing benefit) , the relevant authority must reduce the claimant’s housing benefit by such amount as will leave the claimant entitled to that minimum amount.
