A practical guide for landlords on Article 4 Directions affecting HMOs in London, explaining when planning permission is required, compliance risks, and how Fraser Bond supports property investment and management.
In many London boroughs, Article 4 Directions have changed the rules for converting properties into Houses in Multiple Occupation (HMOs). Landlords and investors must understand these restrictions to avoid enforcement action, fines, or forced property reversions.
Fraser Bond provides expert advice on Article 4 compliance, HMO planning, and licensing, helping landlords protect rental income and optimise investment in London.
An Article 4 Direction is a planning tool used by local authorities to remove permitted development rights. For HMOs, this means:
Converting a single dwelling (C3) into a small HMO (C4) often requires planning permission
Applies in areas with high HMO concentration or specific housing needs
Boroughs such as Camden, Hackney, Islington, and Haringey have active Article 4 zones
Even small HMOs that previously did not require planning consent now fall under council approval.
Before converting a property or purchasing an HMO in London, landlords should assess:
Whether the property falls within an Article 4 zone
Existing HMO concentration in the area
Local planning policies and borough HMO strategies
Minimum room sizes, fire safety, and amenity requirements
Potential impact on parking, waste, and neighbours
Ignoring Article 4 rules can lead to enforcement notices, fines, or reversal of HMO conversion.
It is important to remember:
Article 4 concerns planning permission for change of use
HMO licensing (mandatory, additional, or selective) addresses property management and safety compliance
Both requirements must be met before letting the property
Fraser Bond helps landlords navigate both planning and licensing obligations to ensure full regulatory compliance.
Fraser Bond offers:
Article 4 HMO advice and risk assessments
Planning application guidance and documentation support
HMO licensing compliance checks
Portfolio-wide regulatory monitoring
Strategic investment advice for HMO properties
Proactive planning and compliance reduce risk, protect rental income, and enhance long-term property value in London’s competitive HMO market.
