Damp and mould in an HMO is usually caused by condensation, leaks or rising or penetrating damp, and often by a mix. London is in England. We price damp, mould and HHSRS repairs there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for.
