How Long Does an HMO Licence Take? Processing Times by Council

"How long will this take?" is usually the second question we get asked, right after cost. The honest answer is that it depends significantly on which council is processing your application — London's 33 boroughs do not operate to a shared timetable, and the gap between the fastest and slowest can be considerable.

Why processing times vary so much

Each council manages its own HMO licensing team, with its own caseload, its own inspection scheduling, and its own internal service standards. A borough running a large, well-established additional licensing scheme with high application volumes may take longer simply due to backlog, while a borough with a smaller or newer scheme may process applications faster purely because there's less queue.

The general range

Across London, published and typical processing times for a complete, correctly-submitted HMO licence application commonly run from around 8 weeks at the faster end to as long as 16 weeks at the slower end. Some councils publish a target timescale; others do not commit to one publicly at all.

What actually slows an application down

In our experience, the single biggest driver of delay isn't the council's baseline speed — it's an incomplete or incorrect application requiring back-and-forth queries, which can add weeks regardless of which borough you're in. A complete, accurate submission with all required documentation attached the first time is the most reliable way to land toward the faster end of a council's own range.

Why we recommend applying well ahead of any deadline

Because of this variance, and because a licence can't simply be rushed by asking nicely, we recommend building in a comfortable buffer — particularly for renewals (see our separate renewal timing article) where a gap in licence coverage carries the same penalties as never having applied.

We manage the timeline for you

As part of our service, we prepare a complete, fully-compliant application from the outset specifically to avoid query-driven delays, and we can tell you the typical processing time for your specific borough before you commit, so you know what to expect rather than guessing.
