Landlord Licensing Explained: Mandatory, Additional and Selective Licensing, and How to Check Which Applies to You

England has three landlord licensing regimes, and the reason the subject feels confusing is that only one of them applies everywhere. Mandatory HMO licensing follows the property: a larger shared house needs a licence wherever it stands. The other two, additional HMO licensing and selective licensing, follow the map: they exist only where your council has switched them on, street by street. So the question "do I need a landlord licence?" has no national answer. It has a four-fact answer: how many people live in the property, how many households they form, which council area it sits in, and whether that council has a designation running. Below: the decision path through those four facts, the council check, real 2026 fee schedules, and the tax position.

Everything below is England, under the Housing Act 2004. Wales runs a separate national scheme (Rent Smart Wales) under which every landlord must register and be licensed, and Scotland and Northern Ireland have their own registration and HMO regimes. A licence under one nation's rules counts for nothing under another's.

This is the orientation guide. If you already know which regime catches you and want the statute in detail, the designation machinery, and the full enforcement stack section by section, our HMO and selective licensing compliance guide takes the statute apart section by section, and you will be handed over to it at the right points rather than made to read it twice.

The three licensing regimes in one screen

All three regimes live in the Housing Act 2004: HMO licensing in Part 2 (ss.55 to 78) and selective licensing in Part 3 (ss.79 to 100). Here is the whole framework in one table.

Regime	Which properties	Where it applies	Legal basis
Mandatory HMO licensing	HMOs occupied by 5 or more people forming 2 or more households	Everywhere in England, no local scheme needed	HA 2004 Part 2 plus SI 2018/221
Additional HMO licensing	HMOs outside mandatory scope, typically 3 or 4 unrelated sharers	Only in areas the council has designated	HA 2004 ss.56 to 60
Selective licensing	Every privately rented home, including single-family lets	Only in areas the council has designated	HA 2004 Part 3

The middle column carries the two facts most often got wrong. Mandatory licensing is about headcount, not location: five sharers in two or more households need a licence whether the house is in Newcastle or Truro. Selective licensing is about location, not headcount: inside a designation, a one-tenant flat needs a licence just as a shared house does.

A designation is simply the legal act by which a council switches additional or selective licensing on for a defined area, for up to five years at a time. How councils bring one in, the consultation and approval thresholds, and the section-by-section mechanics all belong to the compliance mechanics guide; all you need here is that designations exist, they are local, and they change.

The two-minute decision path

Take one property at a time and answer four questions in order. Stop at the first "yes".

1. Do five or more people live there, forming two or more households? A household is a single person or members of the same family, so a couple plus three friends is four households, while a family of six is one. If yes: mandatory HMO licensing applies, wherever the property is. You need a licence. Stop here.
2. Is it a smaller HMO? Three or four occupants forming two or more households and sharing a kitchen, bathroom or toilet is still an HMO under s.254, just not a mandatory-licensing one. If yes: check whether your council runs an additional licensing scheme covering the address. Inside a scheme, you need a licence.
3. Whatever the property type, is the address inside a selective licensing designation? This is the question single-let landlords skip because they assume licensing is an HMO subject. Check it anyway: if the address is in a designated area, you need a licence for an ordinary family let too.
4. None of the above? No licence is needed today. New designations start every year, so recheck when you buy, when tenants change, and annually across a portfolio. Licensing is also separate from the national landlord database and redress requirements arriving under the Renters' Rights Act 2025, which apply regardless of licensing; see our redress scheme enrolment guide for that parallel obligation.

Steps 1 and 2 turn on the people in the property; step 3 turns on the dot on the map. That is why one portfolio can need licences under three different regimes at once: a six-bed student house (mandatory), a three-sharer flat in a borough with an additional scheme, and a single family let that happens to sit in a selective area.

How to check your council in practice

Every step of the decision path that says "check your council" comes down to the same ten-minute workflow.

• Search the council website directly. Search the council's own site for "selective licensing", "additional licensing" or "property licensing". Almost every council with a scheme publishes a page naming the designated areas and dates. For cross-boundary streets, confirm which council the property is actually in against the council tax bill.
• Use the designation map or postcode checker. Councils with ward-level or street-level schemes usually publish an interactive map or an address checker. Enter the postcode of the let property rather than your own.
• Check the public register. Councils must keep a public register of licences granted (HA 2004 s.232). If the previous owner or a neighbouring landlord holds a licence, a scheme is probably live in the area. When buying, ask the seller for their licence and check the register as part of due diligence.
• Note the scheme dates. Additional and selective designations run for up to five years and then lapse or are re-made. A scheme that ended last year does not bind you; a scheme starting in three months does.
• If in doubt, ask in writing. Email the council's private sector housing team with the full address and the occupancy (how many people, how many households) and ask which, if any, scheme applies. "The council told me no licence was needed" is a far stronger position with the email attached.

Do this per property and per council. Properties in three boroughs mean three sets of schemes, three fee schedules, and potentially three different sets of licence conditions.

What counts as an HMO here

The gateway definition for the two HMO regimes sits in s.254 of the Housing Act 2004, and its floor sits in Schedule 14. Under the standard test, a property is an HMO where it is occupied by people who do not form a single household and two or more of those households share one or more basic amenities: a toilet, personal washing facilities or cooking facilities. A building occupied by only two people forming two households is taken out by Schedule 14, and that exclusion is where the familiar three-person threshold actually comes from. "Household" does the rest of the heavy lifting: a single person is a household, and so is a family unit, so three friends sharing a kitchen are three households and an HMO, while a couple and their two adult children are one household and not an HMO. Section 254 also carries variant tests for converted buildings and certain flats, which matter for some conversions but not for the basic decision.

Being an HMO is necessary but not sufficient for a licence. The licensing trigger comes one level up:

• Mandatory licensing bites when the HMO is occupied by five or more people forming two or more households. That threshold is set by the Licensing of Houses in Multiple Occupation (Prescribed Description) (England) Order 2018 (SI 2018/221), which since 1 October 2018 has applied the test nationwide and removed the old three-storey requirement. Bungalows and two-storey houses count just as tall townhouses do.
• Additional licensing catches HMOs below that threshold, but only where the council has designated the area. The typical scheme covers three- and four-person HMOs, though the precise scope is set by each designation.

The practical error is counting bedrooms instead of people and households. A five-bed house let to a family of five is not an HMO at all; the same house let to five nurses is a mandatory-licence HMO. The property did not change, the households did, which is also why a licence position can flip mid-tenancy when one sharer moves a partner in and the headcount crosses five.

Yes, selective licensing catches ordinary single lets

Selective licensing is the regime that surprises landlords, because it has nothing to do with sharing. Under Part 3 of the Housing Act 2004, a council can designate an area within which every privately rented dwelling must be licensed: the two-bed terrace let to a couple, the flat let to a single professional, the house you let to one family for eight years. If the address is inside the designation, the tenancy type is irrelevant.

Councils use these designations in areas with poor housing conditions, high anti-social behaviour, low demand or concentrations of poorly managed stock; some cover an entire city, others a handful of wards. Designations run in dozens of local authority areas across England, around 70 of them at the last count, and the list moves every year as schemes start, end and are renewed. That churn is why the check-your-council workflow is an annual discipline rather than a one-off: a property that needed no licence when you bought it can fall inside a new designation you will only hear about if you are looking.

Even inside a selective area, some lettings are exempt (for example, most holiday lets and lettings by registered providers), and a property already licensed as an HMO does not need a second, selective licence on top. The exemption detail sits with the council's scheme documents and the mechanics guide.

What a licence costs and how long it lasts

Fees are set locally by each council, so no national guide can quote you a single number; what follows is the verified shape of the market. The ranges are drawn from council fee schedules and licensing trackers checked on 15 August 2026. Treat them as the band a real figure should fall inside, and confirm the live fee on your own council's page before applying, because schedules are revised most years.

Licence type	Typical fee range (2026)	Term	Cost per year of term
Mandatory HMO licence	£900 to £1,900 per property	Up to 5 years	Roughly £180 to £380
Additional HMO licence	£600 to £1,900 per property	Up to 5 years	Roughly £120 to £380
Selective licence	£500 to £1,000 per property	Up to 5 years	Roughly £100 to £200

Named examples behind those ranges, each checked on 15 August 2026: Bristol charges £1,886 for a new mandatory HMO licence (£1,121 on application, £765 on grant), with renewals at £1,564, for a five-year licence. Liverpool's selective licence is £704, split £232.32 on application and £471.68 on grant, with discounts including £64 for an EPC of C or better. Camden's additional HMO licence fee is £1,531 with a £100 discount for accredited landlords (schedule current as at March 2026). Birmingham's mandatory HMO licence runs at around £1,430 for the five-year term according to licensing fee trackers. Across London boroughs generally, HMO licence fees mostly land between £600 and £1,500. Several schemes, Nottingham's selective scheme among them, also price by track record, with lower fees for accredited landlords and higher tiers where the council has compliance concerns.

Councils split the fee because a court told them to. Following R (Gaskin) v Richmond upon Thames LBC [2018] EWHC 1996 (Admin), councils may only charge up front for the cost of processing the application itself, so most now split the fee into a Part A application charge and a Part B charge on grant covering the running of the scheme; if you withdraw or are refused, Part B is not payable. The other oddity is the term: because the licence lasts up to five years (most councils grant the full term), the honest way to read a fee is per year of term: Bristol's £1,886 is £377 a year, Liverpool's £704 is £141 a year. That is the number to line up against your other recurring compliance costs, and to feed into our portfolio profitability calculator as a per-property expense line.

Budget alongside the fee for the conditions the licence carries: an annual gas safety record supplied to the council, a declaration as to the safety of electrical appliances and furniture on demand (and, under most councils' own conditions, an EICR as well), working smoke alarms, and suitability for the number of occupants. Those certificates have their own price tags, covered in our EICR cost guide and gas safety certificate cost guide, and an HMO application will often surface works the council expects done, from fire doors to amenity upgrades, which are the genuinely variable cost of licensing.

A worked example makes the arithmetic concrete. Amara and Josh let a five-bedroom house to five sharers in a borough that also runs an additional licensing scheme. The scheme is irrelevant to them: at five occupants in five households, mandatory licensing applies, and would in any borough. Their council charges £1,350 for the five-year licence, split £800 on application and £550 on grant. In their property accounts that is £270 a year against a rent roll of £32,400, under one per cent of turnover, and the whole £1,350 is deductible in the year incurred. The fee was never the real cost; the £4,200 of fire safety works the inspection flagged was. Whether that £4,200 is deductible turns on the repair-versus-improvement split, which our fire risk assessment cost guide works through line by line. Figures illustrative.

What happens if you skip it

Letting a property that needs a licence without one is a criminal offence: s.72 of the Housing Act 2004 for HMOs, s.95 for selective areas, each carrying an unlimited fine on summary conviction. In practice councils more often use the civil route: a financial penalty of up to £40,000 per offence under s.249A, imposed by the council as an alternative to prosecution. The cap rose from £30,000 to £40,000 on 1 May 2026 (SI 2026/319). On top of either route, tenants or the council can apply to the First-tier Tribunal for a rent repayment order clawing back up to two years of rent, the window having been doubled from 12 months by the Renters' Rights Act 2025 with effect from the same date, and repeat offenders face banning orders that end their letting business altogether. "Per offence" matters for portfolios: three unlicensed properties is three offences, and an otherwise immaculate landlord with one property on the wrong side of a designation boundary is exposed on that one property in full.

That is the summary. The full enforcement stack, defences, the fit-and-proper-person test and how councils run these cases are set out in the compliance mechanics guide, which is where to go if you are already in difficulty or want the statute in depth.

Buying, selling, incorporating: licences do not transfer

A licence attaches to the person, not the building. Section 68(6) of the Housing Act 2004: a licence may not be transferred to another person. Three situations where that line costs real money:

• Buying a tenanted property. The seller's licence dies with the sale. You need your own application submitted before you take over a licensable letting, so the application and its fee belong on your completion checklist, next to the deposit re-registration and the gas record. An application duly made protects your position while the council processes it.
• Death of the licence holder. The licence ceases on death, but s.68 provides a soft landing: a deemed temporary exemption for three months from the date of death, and the personal representatives can ask the council for a further three months. Executors should diarise both dates, because the estate is the person in control once they expire.
• Incorporating your portfolio. Your company is a new legal person, so moving properties into it, typically via a s.162 incorporation, means a fresh licence application for every licensable property at the council's current fee. There is no discounted "change of holder" route.

The incorporation point deserves numbers. Priya holds four houses in a city with a borough-wide selective scheme and incorporates the portfolio. Four properties means four fresh applications at, say, £750 each: £3,000 of licensing cost triggered purely by the change of legal owner, on top of the SDLT and finance costs of the move. The £3,000 is deductible for the company as a revenue expense of its rental business, but it is cash out in year one, and until each application is in, the company is in control of an unlicensed property in a selective area. Sequence the applications alongside the transfer.

The tax position: fees deductible, penalties are not

Licensing sits in your tax return in four distinct ways, and the asymmetry between them is the point.

Licence fees are deductible. A licence fee, first application or renewal, mandatory, additional or selective, is a revenue expense incurred wholly and exclusively for your rental business and is deductible against rental income under the property business rules (ITTOIA 2005 s.272 applies the trading principles). Deduct it in full in the year incurred; you do not spread it over the five-year term. The full treatment, including agents' handling fees and the company-side position, is in our licence fee deductibility guide.

Penalties are not. A s.249A civil penalty or a criminal fine is a punishment for breaking the law, and HMRC's long-standing position (BIM38500 onwards) is that such penalties are not deductible against your profits. A £40,000 penalty is therefore £40,000 of post-tax money, which for a higher-rate landlord is the profit on a great many months of rent.

A rent repayment order is repaid out of taxed income. The rent you received while unlicensed was taxable when it arrived, and repaying up to two years of it under an RRO does not unwind that. The repayment is not a deductible expense of the business. In cash terms an RRO can therefore cost you more than the rent itself: you hand back gross rent you have already paid tax on, alongside any penalty, and the tax you paid on it stays paid.

The licence holder must match the landlord entity. Deductibility does not care whether you hold property personally or through a company, but the licence does: the holder should be the person or company actually in control of the letting. A licence in your own name does not cover your company's tenancy, which is why incorporation triggers fresh applications, and why a licence held by a departed business partner or a dissolved management company is a compliance hole rather than a formality.

So: count the people and households, check the map, and treat the fee as a modest, deductible, five-year cost of doing business, because everything on the enforcement side is larger and comes out of taxed money. If your portfolio spans more than one council, or you are weighing an incorporation and have not yet priced the re-licensing round, put licensing on the agenda for your next conversation with a property tax specialist before the council, or a tribunal, prices it for you.
