Warrington’s Borough-Wide HMO Planning Permission: What Landlords Must Do Now

Warrington Council Targets HMO Over-Concentration with Borough-Wide Article 4 Direction

Warrington Council has announced plans to extend its Article 4 Direction borough-wide, meaning landlords must obtain planning permission before converting family homes into Houses in Multiple Occupation (HMOs). This policy, effective from September 2026, aims to address concerns such as noise complaints, parking pressures, and impacts on local character.

Why This Matters to Warrington Landlords

Currently, some areas of Warrington permit HMO conversions without planning permission, provided other licensing is in place. The new borough-wide Article 4 Direction removes this automatic right and requires planning applications for all HMO conversions.

Key points:

  • Planning Permission Not Guaranteed: Applications may be refused if the council determines the local area would be adversely affected by high HMO concentrations or related issues.
  • Emerging HMO Standards: Alongside the Article 4 Direction, a Supplementary Planning Document (SPD) is being drafted to set minimum space, facilities, and management standards for HMOs.
  • Potential Delays and Costs: Applying for planning permission can delay conversions and might involve additional professional fees.

Impact by Landlord Type

  • Single-Unit Landlords: Must apply for planning permission for any new HMO conversions from September 2026. Existing HMOs will not be affected but extensions will require approval.
  • HMO Portfolio Owners: Should factor in longer lead times and the risk of refused applications when planning growth.
  • Accidental Landlords: Need to check if their properties meet forthcoming SPD standards and prepare for potential enforcement actions.

Steps to Prepare Now

  1. Audit Properties: Identify current HMOs and potential conversions.
  2. Engage with Consultations: Review council drafts of the SPD and planning documents.
  3. Plan for Applications: Budget for fees, professional advice, and application timelines.
  4. Review Property Standards: Begin upgrading properties to meet anticipated SPD requirements.
  5. Adjust Strategies: Incorporate the planning permission process into acquisition and conversion plans.

Benchmarking and Uncertainties

While precise SPD details and application fees are pending, similar policies in other councils set standards on bedroom sizes, communal areas, and management plans. Reviewing neighbouring authorities’ SPDs, such as Cheshire West and Chester, can provide useful context.
