HMO

My HMO might need a licence it does not have: what now?

Last updated 7 July 2026 · Reviewed by Nick Thorpe, founder

The short answer

If your Huddersfield or Leeds property has five or more people from two or more households sharing a kitchen or bathroom, it likely needs an HMO licence. Kirklees runs mandatory licensing only; Leeds adds selective schemes and Article 4 areas. Apply now rather than wait to be found: penalties and rent repayment orders both bite hard.

Count the people, then count the households

Work out whether you actually meet the test before you worry about anything else. A property needs a mandatory HMO licence once five or more people, from two or more separate households, live there and share a kitchen or bathroom. That is the national rule under the Housing Act 2004, and it applies whether you set out to run an HMO or just ended up with one.

A household is a single person, or people from the same family, and a couple counts as one. Three unrelated sharers are three households. A family of four plus a lodger is five people from two households, and that alone is enough to tip a property over the threshold, even though it does not look like the classic student house share. If you have never actually sat down and counted, do it now, before reading any further. For the full breakdown of the test, see our Huddersfield HMO licence guide.

The rules are not the same everywhere

Where the property sits changes what else applies on top of the national test.

AreaWhat runsExtra to watch for
Kirklees (Huddersfield)Mandatory licensing only, as of mid 2026None currently. Smaller HMOs (four people or fewer) need no licence
LeedsMandatory licensing, plus selective licensing in designated areasSelective licensing catches properties of any size in those areas; Article 4 controls also apply in some student neighbourhoods

That means the same headcount can land you in different places depending on the postcode. Our Leeds HMO licensing guide covers the designated areas and the Article 4 detail in full. Either way, councils change schemes without writing round to every landlord, so confirm your position with the council directly rather than assuming last year’s answer still holds.

Apply now, don’t wait to be found

If you think you meet the test and don’t hold a licence, the move is straightforward:

  1. Count properly. Occupants and households, based on who actually lives there, not who’s named on the tenancy.
  2. Apply to your council straight away. Don’t wait for a routine inspection, a neighbour complaint or a tenant referral to force the issue.
  3. Get the property up to standard. Licence conditions cover fire precautions, room sizes and enough kitchen or bathroom capacity for the headcount. Our HMO fire safety checklist covers what inspectors look at first.
  4. Ask for help if you’re not sure. A phone call is faster than guessing, and cheaper than guessing wrong.

The council does not send a thank-you card for coming forward, but it is still the queue you want to be in. Landlords who apply before anyone asks tend to have a far easier time of it than landlords who get a letter first.

What’s actually at stake if you don’t

Letting a licensable HMO without a licence is a criminal offence. Councils can prosecute through the courts, where the fine is unlimited, or issue a civil penalty of up to £40,000 instead of prosecuting. Tenants can separately apply for a rent repayment order to reclaim rent they have paid, capped at 12 months’ worth. None of that is a reason to panic; it is the reason to sort the paperwork before anyone else raises it first. “I didn’t realise it counted” is not a defence councils or tribunals accept, so the safer move is always to count, then apply.

Where we fit

If you have found out your HMO needs a licence you don’t have, or inherited one that was left unlicensed, we can take it from wherever it currently sits: licence applications, getting the property compliant, and the tenants themselves. Our HMO rescue service is built for exactly this. Call 01484 981717 and we’ll tell you where you stand before you commit to anything.

Licensing rules change, and this page reflects the position as of mid 2026. We confirm current requirements with the relevant council before every HMO we take on.

Frequently asked questions

How do I know if my HMO needs a licence?

Count how many people actually live there, not just who's named on the tenancy, then count how many separate households they form. If it comes to five or more people from two or more households sharing a kitchen or bathroom, that is a licensable HMO under the Housing Act 2004. A family of four plus a lodger already meets it.

What should I do if I've already been letting without one?

Apply to your council now rather than wait to be found. Continuing to let while unlicensed is a criminal offence, and it doesn't stop being one because nobody has noticed yet. In practice, councils generally take a more reasonable view of landlords who come forward and apply than those who are caught first.

Is the test the same in Huddersfield and Leeds?

The five-or-more, two-or-more-households test is national, so it applies everywhere. Where it differs is what else sits on top: Kirklees (Huddersfield) runs mandatory licensing only, with nothing extra. Leeds also runs selective licensing in designated areas, covering properties of any size, plus Article 4 controls in some student areas, so more Leeds properties need some form of permission.

What actually happens if I don't apply?

Letting a licensable HMO without a licence is a criminal offence. Councils can prosecute, where the fine is unlimited, or issue a civil penalty of up to £40,000 instead of going to court. Tenants can also apply for a rent repayment order, capped at 12 months' rent. None of that is a reason to panic, just a reason to apply now.

Will I be fined even if I didn't know I needed a licence?

Yes. Not realising that a family plus a lodger counts as two households, or miscounting how many people actually live there, is not a defence. The rules apply whether or not you meant to run an HMO, which is exactly why it's worth counting properly and applying the moment you're unsure.
