HMO Licence UK: Mandatory Licensing Rules, Penalties and Selective Licensing by Nation

Whether your property needs a mandatory HMO licence depends on which UK nation it is in, since England, Wales, Scotland and Northern Ireland each set a different threshold for what counts as a licensable house in multiple occupation, and operating one without a licence can mean an unlimited fine, a civil penalty of up to £40,000 in England, or a rent repayment order to the tenants.

England removed its old 3 storey requirement in 2018. Wales never adopted that change: its 2006 Order is still the one in force and still requires 3 or more storeys alongside the 5 person and 2 household tests. The practical effect is that an identical 2 storey house with 5 unrelated tenants in 2 households needs a mandatory HMO licence in England but does not meet Wales's mandatory licensing description, though it could still be caught by a Wales additional licensing designation in some council areas, a separate, area based mechanism.

Scotland and Northern Ireland do not run a "mandatory licensing for bigger HMOs only" tier at all. Every property that meets their lower headcount test, 3 or more people, needs a licence, regardless of how large it is.

What a licence involves

A council will not grant an HMO licence unless the landlord, or the person managing the property, passes a fit and proper person test, and the property meets required standards for fire safety and room sizes. Fees and the exact conditions attached to a licence are set locally by each council, so they vary and should be checked directly with the relevant authority rather than assumed to be a fixed national figure.

Penalties for operating without a licence

Operating an HMO that should be licensed but is not is an offence in England and Wales under the Housing Act 2004. On summary conviction the fine is unlimited, following a change that removed the previous fixed cap, commenced on 12 March 2015 (legislation.gov.uk: Housing Act 2004, section 72). In England, instead of prosecuting, a local housing authority can impose a civil penalty of up to £40,000 per offence; this power does not apply in Wales. This cap was raised from £30,000 with effect from 1 May 2026, so any source still quoting £30,000 is now out of date (legislation.gov.uk: Housing Act 2004, section 249A). The same civil penalty regime covers the equivalent selective licensing offence under section 95, failure to comply with an improvement notice, and breach of the HMO management regulations, among others.

Since 1 May 2026, the Renters' Rights Act 2025 changed who can commit the unlicensed HMO offence. It now extends liability up the ownership chain: alongside the person managing the HMO day to day, a landlord or licensor whose interest is superior to that person's, for example a head lease owner renting to a sub landlord who actually runs the unlicensed HMO, also commits the offence (legislation.gov.uk: Housing Act 2004, section 72). A superior landlord has a defence if they did not know, and had a reasonable excuse for not knowing, that the property was an HMO, took all reasonably practicable steps to get it licensed, or had some other reasonable excuse; a term in the tenancy or licence alone is not enough (same source).

Rent repayment orders

In England, a tenant or a local housing authority can apply to the First-tier Tribunal for a rent repayment order under the Housing and Planning Act 2016 against a landlord who committed certain offences, including operating an unlicensed HMO under section 72 or an unlicensed selectively licensed property under section 95. A tenant must apply within 2 years of the offence. The definition of landlord for this purpose includes a superior landlord who committed the offence, mirroring the extension described above (legislation.gov.uk: Housing and Planning Act 2016, section 40; section 41). In Wales, rent paid for an unlicensed HMO can instead be recovered through a rent repayment order under sections 73 and 74 of the Housing Act 2004, a separate scheme with its own rules (legislation.gov.uk: Housing Act 2004, section 73).

The amount is capped at the rent actually paid, over a period of up to 2 years during which the landlord was committing the offence, minus any Universal Credit paid toward that rent for the same period. The tribunal also weighs the conduct of both landlord and tenant, any rent the tenant received from subletting, the landlord's financial circumstances, and any previous convictions, financial penalties or rent repayment orders against the same landlord (legislation.gov.uk: Housing and Planning Act 2016, section 44).

Scotland: landlord registration instead of selective licensing

Scotland does not run an area based selective licensing scheme in the England and Wales sense. Instead, every private landlord in Scotland must be on the local authority's Landlord Registration Scheme, regardless of where the property is. Registration must be renewed every 3 years, and letting a property without being registered is a criminal offence carrying a fine of up to £50,000 (mygov.scot: landlord registration).

Selective licensing in England and Wales

Under Part 3 of the Housing Act 2004, a local authority in England or Wales can designate a whole area, where every private rented property, HMO or not, needs a selective licence, typically in response to poor property conditions, deprivation or anti social behaviour. This is a local, discretionary decision rather than a national rule, so whether it applies to a specific property depends entirely on whether that council has made a current designation for that area. Check directly with the relevant council rather than assuming a figure or a designation applies. Separately from HMO and selective licensing, every private landlord in Wales must register with Rent Smart Wales, and a landlord who lets or manages the property themselves also needs a Rent Smart Wales licence (legislation.gov.uk: Housing (Wales) Act 2014, section 4; Rent Smart Wales); Northern Ireland also requires every private landlord to join its Landlord Registration Scheme (nidirect: landlord registration scheme). Northern Ireland has no separate selective licensing scheme: since it already requires every qualifying HMO to be licensed, there is no additional area based tier to add.

Frequently Asked Questions

How many people trigger mandatory HMO licensing in England?

5 or more people forming 2 or more households. Unlike Wales, England removed its storey requirement in 2018, so even a 2 storey house can need a mandatory HMO licence in England if it meets the person and household test.

Do all UK nations use the same HMO licensing threshold?

No. England needs 5 or more people in 2 or more households with no storey test. Wales needs the same person and household test plus 3 or more storeys. Scotland licenses every property occupied as an only or main residence by 3 or more people from 3 or more families. Northern Ireland licenses every property with 3 or more people forming more than 2 households.

What is the penalty for operating an unlicensed HMO?

In England and Wales, an unlimited fine on summary conviction. In England only, the council can instead impose a civil penalty of up to £40,000 per offence, raised from £30,000 with effect from 1 May 2026. A tenant or council can also seek a rent repayment order.

What is a rent repayment order?

In England, an order a tenant or local housing authority can obtain from the First-tier Tribunal against a landlord, including a superior landlord, who committed an offence such as operating an unlicensed HMO. It is capped at the rent paid over a period of up to 2 years during the offence, minus any Universal Credit paid toward that rent.

Can a superior landlord be prosecuted for an unlicensed HMO they do not manage day to day?

Yes, since 1 May 2026. The Renters' Rights Act 2025 extended the unlicensed HMO offence up the ownership chain, so a landlord or licensor with a superior interest can also be liable, not only the person actually managing the property.

Does Scotland have selective licensing like England?

No, not in the same form. Scotland instead requires every private landlord to be on the local authority's Landlord Registration Scheme, renewed every 3 years, regardless of area. Letting without registration is a criminal offence carrying a fine of up to £50,000.

Does Northern Ireland have selective licensing?

No. Northern Ireland already requires every qualifying HMO to be licensed under its own 2016 Act, so there is no separate area based selective licensing scheme to add on top.
