HMO Planning Permission Advice - London Guidance for Landlords and Investors

Expert insight into HMO planning permission in London, covering Article 4 Directions, change of use rules, and how Fraser Bond supports compliant HMO investment and development strategies.

Do You Need Planning Permission for an HMO in London?

When converting a property into a House in Multiple Occupation, HMO planning permission may be required depending on location and size.

In planning terms:

• Small HMOs (3–6 occupants) fall under Use Class C4

• Larger HMOs (7+ occupants) are classed as Sui Generis

• A change from single dwelling (C3) to C4 may require permission in certain boroughs

In many London boroughs, Article 4 Directions remove permitted development rights. This means planning permission is required even for small HMOs.

Boroughs such as Camden, Islington, Hackney, and Haringey operate Article 4 restrictions, making planning approval mandatory before conversion.

Article 4 Directions and London HMO Planning

An Article 4 Direction allows a local authority to withdraw automatic permitted development rights.

For landlords and investors, this means:

• You cannot convert a family home into an HMO without formal planning consent

• Applications must include floor plans, occupancy details, and impact assessments

• Councils assess local housing concentration and community impact

Failure to obtain required planning permission can result in enforcement notices and reversal of the conversion.

Professional planning due diligence is essential before purchasing a property for HMO investment in London.

HMO Planning Permission vs HMO Licensing

It is important to understand that planning permission and HMO licensing are separate requirements.

You may need:

• Planning approval for change of use

• Mandatory, additional, or selective HMO licence

• Building regulations compliance

Securing one does not automatically grant the other.

Fraser Bond supports landlords with planning assessments, licensing guidance, and compliance audits to ensure full regulatory alignment.

Key Considerations Before Applying

Before submitting an HMO planning application in London, landlords should assess:

• Whether Article 4 applies in the borough

• Existing HMO concentration levels in the area

• Minimum room size standards

• Parking and waste management arrangements

• Local housing policy objectives

A strategic planning approach improves approval prospects and protects investment value.
