HMO Licensing in England: What Every Landlord Must Know in 2026

Running an HMO without understanding your licensing obligations is one of the more expensive mistakes a landlord can make. Civil penalties now reach £40,000. Tenants can claim back up to 24 months' rent. And licensing expansion is accelerating, meaning obligations that did not apply to you last year may apply now.

This guide covers the three tiers of HMO licensing in England, how the rules interact with Article 4 Directions, what licence conditions require, and what has changed in 2026.

The Three Tiers of HMO Licensing

England has three types of property licensing in the private rented sector. They operate independently, and a property can be subject to more than one at the same time.

Mandatory HMO Licensing

Mandatory licensing is a national requirement under the Housing Act 2004. It applies to any property that is:

• Occupied by 5 or more people
• Forming 2 or more separate households
• Who share basic amenities such as a kitchen, bathroom, or toilet

Since October 2018, the number of storeys has not mattered. The Licensing of Houses in Multiple Occupation (Prescribed Description) (England) Order 2018 removed the former three-storey rule. Any number of storeys now triggers mandatory licensing at the five-occupant threshold. A ground-floor flat shared by five unrelated adults needs a mandatory licence. So does a bungalow, a converted warehouse, or a purpose-built block of rooms.

This catches more properties than many landlords realise. If you let a five-bedroom property to five separate individuals, each forming their own household, you need a mandatory HMO licence regardless of the building type.

Additional Licensing

Additional licensing is a discretionary scheme that councils can introduce under Section 56 of the Housing Act 2004. It extends licensing to smaller HMOs that fall below the mandatory threshold, typically properties with 3 or 4 occupants.

Councils must designate an additional licensing area by formal decision, publish notice, and give landlords time to apply. Once a scheme is in force, any HMO within the designated area that meets the scheme's definition requires a licence even if it does not hit the five-occupant mandatory trigger.

Over 70 English councils now operate additional HMO licensing schemes. Among the councils with confirmed additional schemes are Bristol, Nottingham, Brighton and Hove, Liverpool, Sheffield, Oxford, Salford, Waltham Forest, Havering (from March 2026), and Reading (from March 2026).

Before buying or letting a smaller HMO, check whether the council has an additional licensing scheme in place. The absence of mandatory licensing obligations does not mean the property is licence-free.

Selective Licensing

Selective licensing applies to all private rented properties in a designated area, regardless of occupancy level or HMO status. A single-occupancy buy-to-let in a selective zone needs a licence in the same way a three-bedroom shared house does.

Councils can designate selective licensing areas where a condition is met, such as low housing demand, significant anti-social behaviour, or poor property conditions. Schemes must be reviewed and renewed every five years.

Over 60 English councils ran selective licensing schemes by early 2026, including Rotherham (from February 2026), Havering (from March 2026), Newham, Southwark, Leeds, Salford, and others.

Since December 2024, councils no longer require central government approval for large-scale selective licensing schemes. Previously, any scheme covering more than 20% of a council's private rented stock needed Secretary of State approval. Removing that requirement has accelerated new designations, and more schemes are expected throughout 2026 and 2027.

Check the local council's housing pages for each area where you own property. The MHCLG selective licensing database is a useful starting point.

Licence Fees

Fees are not set nationally. Each council sets its own fee structure, and charges vary considerably.

As a guide based on 2026 data:

• National average for a five-year mandatory HMO licence: £700 to £900
• Typical range: approximately £500 to over £1,500 depending on council area
• London boroughs: £1,000 to £1,800 (inner London boroughs tend to be at the higher end)
• Regional city councils (Manchester, Liverpool, Birmingham, Leeds): £900 to £1,200
• Selective licensing: £350 to £900 per property for a five-year licence

Many councils split the charge into an application fee (paid on submission) and a grant fee (paid on approval). Some offer discounts for accredited landlords.

An HMO licence is valid for up to five years. Build both the initial cost and renewal into your cashflow model. HMO licensing costs are tax-deductible: HMRC treats licence fees as an allowable revenue expense under property income rules.

Penalties for Operating Without a Licence

The financial consequences of running an unlicensed HMO are significant.

Civil penalty: Local councils can impose a civil penalty of up to £40,000 per breach. The Renters Rights Act 2025 (from 1 May 2026) raised this from the previous £30,000 ceiling. GOV.UK guidance sets a national starting point of £17,000 for failure to licence an HMO, scaling to the £40,000 maximum based on culpability and harm.

Rent Repayment Order: Tenants can apply to the First-tier Tribunal for a Rent Repayment Order. For offences from 1 May 2026 onwards, the maximum award is 24 months' rent, doubled from the previous 12-month ceiling by the Renters Rights Act 2025. The application does not require a criminal conviction against the landlord.

Criminal prosecution: Operating without a licence is a criminal offence. Councils typically take the civil penalty route, but prosecution remains available.

Both routes are used by councils that actively enforce housing standards. Non-compliance with licence conditions (room sizes, fire safety, management standards) is a separate breach from operating without a licence entirely.

Licence Conditions

When a local authority grants an HMO licence, it attaches conditions. National minimum standards apply, and councils can add local conditions on top.

Room sizes: prescribed nationally. A bedroom for a single adult must be at least 6.51 square metres; for two adults, 10.22 square metres. Rooms used by children under ten have a lower threshold of 4.64 square metres.

Fire safety: interlinked smoke alarms on every floor, a heat detector in the kitchen, and carbon monoxide detectors where there is a solid fuel appliance are standard requirements. Fire doors to bedrooms and kitchens are typically required in larger HMOs.

Gas and electrical safety: a valid Gas Safety Record (GSR) must be renewed annually. An Electrical Installation Condition Report (EICR) must be renewed every five years. Both are licence conditions as well as standalone legal requirements.

Management standards: common parts must be kept clean and in good repair. Refuse facilities appropriate to the number of occupants must be provided. The landlord must respond to repairs and maintain the property in a condition fit for the number of occupants licensed.

Failing to meet conditions mid-licence is a breach even if the original application was compliant. Councils can vary or revoke licences where conditions are not met.

Article 4 Directions and Planning Permission

Licensing and planning permission are separate requirements, but they interact for anyone planning a new HMO conversion.

An Article 4 Direction is made by a local planning authority to remove a permitted development right. In the HMO context, the relevant right is the change of use from a dwellinghouse (Use Class C3) to a small HMO (Use Class C4, covering properties with 3 to 6 occupants).

Without an Article 4 Direction, converting a C3 property to a C4 HMO does not require planning permission anywhere in England. Where an Article 4 Direction is in force, planning permission is required before the conversion can happen.

Over 100 English authorities had HMO-specific Article 4 Directions in place by early 2026. In London, 22 of the 33 planning authorities have directions in place.

Recent new designations include Ealing (borough-wide, November 2025), Hillingdon (December 2025), and Merton (completed March 2026). Erewash Borough Council confirmed a new Article 4 Direction at Full Council in March 2026, with the direction coming into effect in March 2027. South Ribble approved a direction in January 2026.

For large HMOs with 7 or more occupants (sui generis use), planning permission is always required regardless of whether an Article 4 Direction is in place. There are no permitted development rights for sui generis HMO conversions.

Where an Article 4 Direction and mandatory licensing both apply, you need both planning permission for the conversion and an HMO licence for the management of the property. Satisfying one does not meet the obligation for the other.

The Application Process

HMO licences are applied for through the relevant local council. Most councils have online portals. You will typically need to supply proof of identity, a floor plan showing room sizes, current gas safety and electrical certificates, an EPC, evidence of fire safety compliance, and a declaration that you are a fit and proper person.

The fit and proper person test looks at unspent criminal convictions, previous licensing refusals or revocations, and any civil penalties in the landlord database.

Typical processing time is 4 to 12 weeks. A licence is valid for up to 5 years. Submit renewal applications before the existing licence expires.

Practical Checklist

Before letting a property as an HMO, work through the following:

1. Check whether mandatory licensing applies based on occupancy and household composition.
2. Confirm whether the council operates an additional HMO scheme covering the property.
3. Check whether a selective licensing scheme applies to the postcode.
4. If converting a C3 property, verify whether an Article 4 Direction applies before exchanging contracts.
5. Confirm room sizes meet national minimum standards before any bedroom is let.
6. Ensure gas safety, electrical, and fire safety compliance before occupation.
7. Build licence fees and five-year renewal costs into your cashflow model.

When buying an existing HMO, check that the current licence is valid and covers the current occupancy level. A licence does not transfer on sale: you will need to apply for a new one in your own name.
