Damp and mould in an HMO is usually caused by condensation, leaks or rising or penetrating damp, and often by a mix. In Portsmouth, a place of roughly 210,000 people in Hampshire, the work is planned around the HMO rules for England and the council’s written HMO standards. Portsmouth has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
