A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. In St Helens, a place of roughly 180,000 people in Merseyside, the work is planned around the HMO rules for England and the council’s written HMO standards.

Which rules apply in St Helens?
House to HMO conversion in St Helens must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
