HMO Planning Permission in
London
London has an Article 4 direction covering small HMOs, which means converting a family home into a house in multiple occupation here almost always needs full planning permission – the usual permitted development route doesn’t apply. Our local specialists know exactly what London’s planning authority expects to see.

Article 4 directions exist specifically to give councils more control over HMO conversion in areas under particular pressure, and London is one of the places where this applies to small HMOs specifically. What would be a straightforward, permission-free conversion elsewhere needs full planning consent here.
Because this Article 4 status catches a lot of landlords and developers off guard, working with someone who already knows London’s specific requirements avoids a costly mistake.
Beyond the Article 4 requirement itself, London HMO applications still need to satisfy the same licensing rules as everywhere else – mandatory licensing kicks in at 5+ occupants from 2+ households, with national minimum room sizes applying regardless of planning status.

From there, we advise honestly on exactly what London requires for your specific project, rather than a generic HMO checklist that doesn’t account for local rules.

Why London’s Article 4 Status Matters
HMO rules genuinely vary by location and property, and London is no exception. We give you a clear, accurate picture of what’s actually required here, not generic national guidance that misses local specifics.
London’s HMO rules can shift as council policy develops, so we work from current, verified information rather than outdated assumptions about what does and doesn’t need permission.
HMO projects in London often feel more complicated than they need to be, mainly because planning, licensing, and room-size rules get conflated. We untangle exactly what applies to your specific project from the outset.
