The short answer
London has no single rulebook. Mandatory HMO licensing at five occupants is national, but everything above it — additional and selective schemes, fees, amenity standards, enforcement appetite — is set by each of the 33 authorities. At least 22 boroughs have Article 4 directions removing the automatic right to convert a house into a small HMO.
London is the most consequential compliance market in the sector and the one where the rules change most often. Two properties three miles apart can face different licence types, different fees, different amenity standards and different planning positions, and none of that is visible from the listing.
This page is the structural version — what applies, why it varies, and the sequence to check it in. For the borough-by-borough detail, current fee examples and the application mechanics, we keep a longer guide that we update as schemes change.
What applies in London
Mandatory HMO licence
RequiredRequired across every London borough when five or more people forming two or more households share a kitchen, bathroom or toilet. National threshold, no local variation, no coliving exemption.
- In force ·
- Since October 2018 (current threshold)
- Cost ·
- Varies by borough — Tower Hamlets £977; Westminster £1,540 plus £68 per letting above five; Camden roughly £1,300–£1,570

Additional licensing
Depends on addressBoroughs may license smaller HMOs below the mandatory threshold. Designations run up to five years and are renewed, redrawn or allowed to lapse, so a property can move in and out of scope mid-tenancy.
- Cost ·
- Tower Hamlets additional licence £1,323; other boroughs vary widely

Selective licensing
Depends on addressIn designated areas, ordinary single lets require a licence too. Separate designation from additional licensing and often covers different wards within the same borough.

Article 4 direction
Check before you buyAt least 22 London boroughs have directions removing permitted development for C3 to C4 conversion — some borough-wide including Tower Hamlets, Newham and Barnet, others ward-specific. Where one applies, converting a family house to a small HMO needs full planning permission.
Minimum sleeping room sizes
RequiredNational mandatory licence conditions set floor areas: 6.51 m² for one person over 10, 10.22 m² for two, and 4.64 m² for a child under 10. A room below the threshold cannot be licensed as sleeping accommodation.
- In force ·
- Since 1 October 2018
Large-scale purpose-built shared living
Depends on addressSchemes of 50 or more private rooms with shared facilities are sui generis under London Plan Policy H16, routed through a viability-tested process with an affordable contribution expected at the equivalent of 35% of units — 50% on public or eligible industrial land.

Local trap
The trap: buying before checking Article 4
The sequence we see repeatedly is an operator finding a well-priced family house in a strong rental ward, running the numbers on a six-bed conversion, exchanging, and then discovering the borough removed permitted development rights years ago. What was a straightforward conversion becomes a full planning application in a borough whose policy may be actively resisting HMO concentration.
The check takes minutes and has to happen before exchange. Article 4 status is published by the borough and is address-specific — a direction can cover the whole borough or only certain wards, and the boundary does not follow anything intuitive.
Before you commit capital in London
- 01Confirm the borough and check its live licensing schemes — mandatory, additional, selective — on the council's own page, not an aggregator.
- 02Check Article 4 status for the specific address, not the postcode district.
- 03Measure every intended sleeping room against the 6.51 m² / 10.22 m² thresholds before you model the bed count.
- 04Price the licence fee for that borough plus any per-letting supplement above five occupants.
- 05Budget for the borough's inspection backlog — a valid, complete application lets you operate lawfully while it is determined.
- 06If the scheme is 50+ rooms in London, take planning advice on Policy H16 before anything else.

Frequently asked questions
Do all London boroughs require an HMO licence for coliving?+
Mandatory licensing applies in every borough at five or more occupants from two or more households sharing facilities. Below that, it depends on whether the borough has an additional licensing scheme in force — many do, and designations change.
How much does a London HMO licence cost?+
It varies by borough. Verified examples: Tower Hamlets £977 mandatory and £1,323 additional; Westminster £1,540 per application plus £68 for each letting above five, with a 10% accredited-landlord discount; Camden in the region of £1,300 to £1,570. Check the borough's current schedule before applying — these change.
Which London boroughs have Article 4 directions?+
At least 22 as of 2026, including borough-wide directions in Tower Hamlets, Newham and Barnet, with others applying to specific wards. Because coverage is address-specific and directions are added over time, check the borough's planning pages for the exact property.
What happens if I operate without a licence?+
Operating a licensable HMO without a licence is a criminal offence carrying an unlimited fine on prosecution. Councils can alternatively impose civil penalties of up to £30,000 per offence, and tenants may seek a rent repayment order.

Why we publish this
We wrote this because the licence decides what your building is allowed to be before any marketing question exists — and we have had to work that out, city by city, for the operators we grow.
StartColiving is a marketing and advisory team working only in coliving — 18+ brands over 8+ years, plus a marketplace of our own. The research on this site is free and stays free; it is how we show our working rather than a lead magnet with a form in front of it.
