Eastbourne Borough Council has introduced new planning controls designed to limit the unchecked proliferation of houses in multiple occupation (HMOs). From 30 July 2025, an Article 4 Direction has come into effect in four areas of the town, requiring property owners to obtain planning permission before converting single-family homes into small HMOs housing 3 to 6 unrelated occupants sharing amenities.

Targeting Over-Concentration in Key Areas

Councillor Stephen Holt, the Leader of the Council and a long-time campaigner for HMO reform, welcomed the change: “I have been campaigning for many years to improve the standard and quality of HMOs. Representing the Devonshire ward, I know that over 70% of registered HMOs are located in this area. I am delighted that after many years we have been able to implement an Article 4 Direction to those places where we have demonstrated an over-concentration.

“I want to be really clear, HMOs play a crucial role in Eastbourne’s housing landscape. By introducing this comprehensive planning guidance and these new controls, this council is showing its commitment to improving living conditions for HMO residents, as well as their neighbours.”

Balancing Supply and Standards

Councillor Peter Diplock, cabinet member for housing, emphasised that the move supports sustainable growth:

“This marks a significant step in ensuring that Eastbourne continues to offer diverse housing options while proactively addressing the impact of high-density HMO areas on our communities. Importantly, it also provides a framework for sustainable development in the town centre.”

What the Changes Mean

• New planning permission required: Any new conversion to a small HMO (3–6 occupants) within designated areas must now go through the formal planning process.

• Grandfathering existing use: Conversions completed before 30 July 2025 are exempt from the new requirement. However, landlords may wish to apply for a Certificate of Lawful Development to confirm their property’s continued lawful use.

• Supplementary Planning Document (SPD): The council has also adopted a new SPD outlining how planning applications for HMOs will be assessed. This includes factors such as:

  • Local HMO concentration

  • Loss of family housing

  • Impact on neighbour amenity

  • Accommodation quality and internal space standards
