HMO Licensing and Selective Licensing: What Private Landlords Actually Have to Do

If you let property in England, there are two separate licensing regimes that can catch you — and confusing them is one of the easiest ways to end up on the wrong side of a council enforcement team. HMO licensing and selective licensing sit under different parts of the same statute, cover different properties, and are triggered in different ways. This guide untangles both for the small landlord, explains what each costs, and sets out why getting it wrong now carries a bigger financial sting than it did a year ago.

TL;DR: HMO licensing and selective licensing for landlords in a nutshell

HMO licensing and selective licensing are two distinct schemes under the Housing Act 2004. A mandatory HMO licence is required nationwide for any house or flat let to five or more people forming two or more households who share a kitchen, bathroom or toilet, according to GOV.UK. Selective licensing is a local, postcode-based scheme where a council requires every private rented home in a designated area — including an ordinary family let — to be licensed. Fees typically run to several hundred pounds per property (commonly in the £600–£900 range for additional and selective licences, though they vary widely by council). Letting an unlicensed property that should be licensed is a criminal offence carrying an unlimited fine on conviction or a civil penalty of up to £30,000 — and from 1 May 2026 tenants and councils can reclaim up to two years' rent through a rent repayment order.

What is the difference between HMO licensing and selective licensing?

The Housing Act 2004 created three licensing routes, and it helps to see them side by side rather than as one blurry "do I need a licence" question.

The crucial distinction for a landlord like Dave with a handful of terraces: HMO licensing is about how many unrelated people live in the property, while selective licensing is about where the property is. A three-bed terrace let to a single family is never an HMO — but if it sits inside a selective licensing designation, it still needs a licence. That is the point most competitor guides gloss over, and it is exactly the point that generates the surprise fine.

Mandatory HMO licensing has applied without a storey threshold since 1 October 2018, so the old "three storeys or more" rule is dead — a two-storey terrace let to five sharers is a licensable large HMO. GOV.UK confirms the current test: five or more occupiers, two or more households, at least one paying rent, sharing a toilet, bathroom or kitchen.

When does a property need a mandatory HMO licence?

A property in England needs a mandatory HMO licence if all of the following apply: it is occupied by five or more people, they form more than one household, and some or all of them share a toilet, bathroom or kitchen. A "household" means a single person or members of one family living together, so five unrelated working professionals sharing a kitchen is the textbook licensable HMO. According to GOV.UK, the council must also carry out a Housing Health and Safety Rating System risk assessment within five years of your application, and can require works if it finds unacceptable hazards.

Beyond the mandatory threshold, your council may run an additional licensing scheme that pulls in smaller HMOs — typically houses shared by three or four people. These are local and time-limited, so a three-sharer house that needs no licence in one borough may need one across the boundary. There is no national register you can rely on; you have to check with the specific council.

What is selective licensing, and why does it feel like a cash grab?

Selective licensing lets a council designate an area — a few streets, a ward, or in principle the whole district — where every privately rented home must be licensed, regardless of how many people live there. The power sits in Part 3 of the Housing Act 2004, section 80, and a council can only designate an area if it can evidence problems such as low housing demand, significant anti-social behaviour, poor property conditions, high migration, high deprivation or high crime, as set out in MHCLG's selective licensing guidance.

The resentment among decent landlords is understandable: you pay a per-property fee for a scheme aimed at problems you did not cause, and the fee can feel like it buys you nothing but a certificate. It is worth knowing where the money legally has to go. The funds raised are ring-fenced to running the scheme — a council cannot use selective licensing income to plug unrelated budget gaps — and licence conditions cannot be used to control your rent.

Selective licensing is about the postcode, not the property. A perfectly ordinary family let can need a licence purely because of the street it's on.

Why selective licensing is spreading faster now

Here is the development that has genuinely changed the landscape, and that most older guidance misses. With effect from 23 December 2024, a new General Approval came into force, and MHCLG's guidance confirms that local housing authorities in England no longer need the Secretary of State's confirmation before introducing a selective licensing scheme of any size. Previously, a scheme covering more than 20% of a council's area or private rented stock needed central sign-off. That brake is gone.

In practice, this means larger, borough-wide schemes are now easier and quicker for councils to roll out. Councils must still consult for at least 10 weeks and satisfy the statutory conditions, but the political friction of getting Whitehall approval has been removed. If you let in an area with older housing stock or a history of anti-social behaviour complaints, the odds of a scheme landing on you have gone up — so watching your council's consultations is no longer optional.

How much do HMO and selective licences cost?

Licence fees are set by each council, not nationally, so there is no single number — which is precisely why landlords struggle to budget for them. As a rough guide, additional HMO and selective licences commonly fall in the £600–£900 per-property range, while mandatory HMO licences are usually higher because they scale with the number of bedrooms.

To ground that: the London Borough of Hammersmith & Fulham, as of 2026, publishes a mandatory HMO fee of £1,387 for a five-bedroom HMO plus £170 per additional bedroom, and £597.50 for an additional HMO or selective licence, with discounts for accredited landlords. Those are illustrative of one council only — your own council's fee could be materially higher or lower.

What happens if you let an unlicensed HMO or unlicensed property?

Letting a property that should be licensed — whether under HMO or selective rules — is a criminal offence. On conviction the fine is unlimited; as an alternative to prosecution, a council can impose a civil penalty of up to £30,000, and a conviction or penalty can also cost you your "fit and proper person" status, jeopardising your other licences. But the change that should focus every landlord's mind is what happens to your rent.

Under section 40 of the Housing and Planning Act 2016, a rent repayment order (RRO) can be made against a landlord who controls or manages an unlicensed HMO (section 72(1)) or an unlicensed house in a selective area (section 95(1)). The Renters' Rights Act 2025 amended these provisions with effect from 1 May 2026. According to Shelter, for offences committed on or after that date an RRO can now require repayment of up to two years' rent — double the previous 12-month cap. A tenant does not need the council to prosecute first; they can apply to the First-tier Tribunal directly, which need only be satisfied beyond reasonable doubt that the offence was committed.

A worked example of the numbers

Say a landlord lets a five-bedroom house share in a Manchester suburb, unaware the storey rule was scrapped, and runs it for 14 months without the mandatory HMO licence. The five rooms bring in £2,400 a month combined. Because the offence period is 14 months, a rent repayment order could in principle reach up to that 14 months of rent the tenants paid themselves — roughly £33,600 — with utility elements stripped out. Layer on a civil penalty of up to £30,000 and the council's own costs, and a single missed licence can wipe out several years of net profit on the property. That is the mechanism behind the headline: the penalty is designed to be larger than the rent you earned by cutting the corner.

There is one further sting. A landlord letting an unlicensed property generally cannot rely on the standard possession routes — with Section 21 abolished from 1 May 2026, unlicensed landlords are also restricted in using the Renters' Rights Act possession grounds. Being unlicensed does not just cost money; it can leave you unable to regain your own property. For how possession now works, see how to end a tenancy after Section 21 abolished, and for the wider enforcement picture, the penalties landlords face for non-compliance in 2026.

What should a landlord actually do?

1. Check the property against the HMO test. If five or more people in two or more households share facilities, it is a mandatory HMO — everywhere, no exceptions for low storeys.
2. Check the postcode with your council. Ask the private-sector housing team whether the address falls in an additional HMO or selective licensing designation. Do not assume a family let is safe.
3. Apply before you let, or immediately if a new scheme lands. An outstanding application is a defence; simply being unlicensed is not.
4. Diarise the expiry. Licences typically run five years and are not transferable. Renew before expiry and re-check on any sale or change of manager.
5. Keep the compliance file current. Gas, electrical and alarm certificates are usually licence conditions — a lapsed CP12 can breach your licence as well as safety law.

Frequently Asked Questions

Do I need a licence for a single-family house?

Only if the property sits inside a selective licensing area designated by your council. A single-family let is not an HMO and needs no HMO licence, but selective licensing under Part 3 of the Housing Act 2004 can require a licence for ordinary family lets in a designated postcode. Check the specific address with your council.

How much is a rent repayment order for an unlicensed property?

For offences committed on or after 1 May 2026, a rent repayment order can require repayment of up to two years' rent, according to Shelter's summary of the Renters' Rights Act 2025 changes. The exact amount is set by the First-tier Tribunal based on the length of the offence and the landlord's conduct, and rent paid by universal credit or housing benefit is claimed by the council rather than the tenant.

Is an HMO licence the same as a selective licence?

No. An HMO licence (mandatory or additional) is triggered by the number and make-up of the occupiers under Part 2 of the Housing Act 2004. A selective licence is triggered by the property's location in a designated area under Part 3. A property is only ever caught by one regime at a time — an HMO in a selective area needs the HMO licence, not the selective one.

How long does an HMO or selective licence last?

Both types of licence usually last up to five years, though a council can grant one for a shorter period. Selective licensing designations themselves run for up to five years before the council must review or renew the scheme. Licences are not transferable, so a new owner or manager must apply afresh.

Can a council fine me and make me repay rent for the same offence?

Yes. A civil penalty of up to £30,000 (or an unlimited fine on conviction) and a rent repayment order are separate mechanisms and can both follow from the same unlicensed letting, alongside recovery of the council's costs. This is why the total exposure from a single missed licence can far exceed the licence fee you avoided.

The bottom line

HMO licensing and selective licensing are not interchangeable, and the safe assumption for any small landlord is to check both the occupancy and the postcode before letting. The regime is not softening — the removal of central sign-off for large selective schemes and the doubling of the rent repayment order cap both point the other way. None of this is a substitute for advice on your specific property; where the facts are borderline, or a council has served a notice, speak to a solicitor or your accredited landlord body.
