HMO licences: what they mean for the people actually living there
What counts as an HMO in England, when a licence is required, what conditions a licence enforces, how to check the register, and rent repayment orders worth up to two years of rent.
Most flatshares in England count as HMOs, and any with five or more people from two or more households needs a mandatory licence, with many councils licensing smaller shares too. A licence enforces minimum room sizes, fire safety and a maximum number of occupants, and every council publishes its HMO register online. If a landlord operates a licensable HMO without a licence, a tribunal can order them to repay the people living there up to two years of rent.
HMO licensing sounds like landlord admin, and mostly it is. But it quietly decides how safe your house is, how many people can legally live in it, and whether you have a claim worth thousands if your landlord skipped the rules.
What counts as an HMO
A house in multiple occupation is a property where at least three people from two or more separate households share facilities like a kitchen or bathroom. Households means families or couples, so three friends sharing a flat are three households, and most flatshares are HMOs whether anyone calls them that or not.
Being an HMO is not a problem. It simply switches on extra duties for the landlord: stricter fire safety, standards for shared facilities, and in many cases a licence.
When a licence is required
Mandatory licensing applies across England to HMOs with five or more people from two or more households. On top of that, councils can run additional licensing for smaller HMOs and selective licensing covering all rented homes in an area. Much of London is covered by one scheme or another, so a four person flatshare in Hackney may well need a licence even though national rules alone would not require one.
The licence is the council's lever. It sets a maximum number of occupants, minimum room sizes (a bedroom for one adult must be at least 6.51 square metres), fire precautions like doors and alarms, and management standards for repairs and waste. A licensed HMO is inspected. An unlicensed one is invisible until something goes wrong.
How to check yours
Every council publishes its HMO register online. Search the address before you move in, or today if you never have. If the property is licensed, the register shows the licence holder and the permitted number of occupants. If your house has seven people and a licence for five, or is not on the register at all when it should be, the landlord has a problem.
Rent repayment orders: the renter's lever
If a landlord operates a licensable HMO without a licence, the people living there can apply to the First-tier Tribunal for a rent repayment order. Since the Renters' Rights Act, a tribunal can order the landlord to repay up to two years of rent. You do not need the council to act first, you apply as the tenant, and Shelter or a housing solicitor can help you build the case. For a room at £800 a month, two years is £19,200. It is the single most underused right in shared housing.
Licensing failures can also block a landlord from recovering possession, and councils can issue fines that run into the tens of thousands.
What a licence does not do
A licence is a floor, not a guarantee of a lovely home or a decent landlord. It does not set your rent, choose your housemates, or make the shower pressure acceptable. Your other rights, on repairs, deposits, notice and privacy, sit alongside it and are covered in your rights in a shared house.
