What is the smallest room I can let?
In a licensed HMO in England, a room for one person aged 10 or over must be at least 6.51 square metres, not counting floor under a ceiling lower than 1.5 metres. Councils can set larger sizes, and Wales, Scotland and Northern Ireland have their own standards. We measure every room before you commit to a layout.

In England a mandatory licence is needed when five or more people from two or more households share, and smaller HMOs can need one where the council runs additional licensing.
