PAS SDS Good Practice Tips for effective working between Strategic and Local Planning Authorities

The aim of the Good Practice Tips for SPA and LPA working is to complement the PAS SDS Readiness Guide and Toolkit (published Feb 2026). They should be used together with tools and templates that will support cross authority working.


Context

Between November 2025 and January 2026, PAS hosted a number of Strategic Planning Authority (SPA) and Local Planning Authority (LPA) workshops with over a hundred participants. To support Spatial Development Strategy (SDS) progress and learning, these focused on cross authority working and strategic and local plan interaction. The strategic areas represent a range of stages of maturity in terms of SDS progress, devolution and local government reform (LGR).

Workshops were held in the following areas:

  • West of England Combined Authority (WECA)
  • North-East Combined Authority (NECA)
  • Liverpool City Region Combined Authority (LCRCA)
  • West Yorkshire Combined Authority (WYCA)
  • Norfolk & Suffolk (N&S) – Devolution Priority Programme (DPP)
  • Greater Essex - Devolution Priority Programme (DPP)
  • Leicester, Leicestershire & Rutland (LLR) – As yet undecided, so SDS duty currently falls on upper tier authorities


The purpose of the sessions was to: 

  • Facilitate collaboration between tiers of local government
  • Improve SDS and Local Plan alignment
  • Identify positives, challenges, commonalties and good practice
  • Develop good practice tips and advice, and guide future focus of support and resourcing. 

Appetite for Strategic Planning at Workshops

All participants were asked how they feel about the return of strategic planning on a scale of 1 (poor) to 5 (very positive). Despite a healthy awareness of the challenges, there was overwhelming positivity from the participants about the re-introduction of strategic planning – with over 80% scoring 4 and 5.

 
Some of the most frequently used words used were - "Excited", "Needed", "Hopeful", "Fun", "Synergy", "Relieved", "Overdue", “Opportunity” and “Cautiously optimistic”.

SPA and LPA Workshop Findings and Good practice

The findings of the Strategic Planning Authority and Local Planning Authority Workshops are focused on learning, good practice tips, and support asks of Government and PAS. They are set out under the following five themes:

  • Theme 1: Governance, Leadership and Strategic Working
  • Theme 2: SDS and Local Plan Interaction
  • Theme 3: Data, Evidence and Digital Tools
  • Theme 4: Housing, Infrastructure and Spatial Strategy
  • Theme 5: SDS readiness at a time of significant uncertainty

Theme 1: Governance, Leadership and Strategic Working

The focus of this theme is leadership, member meetings/decision-making between strategic and local planning authorities along with officer meetings and collaboration. 
 

Across all areas, there was an interest in establishing:
 

  • Member-level SDS Vision groups
  • Introducing standing SDS agenda items at officer meetings
  • Clear Terms of Reference (ToR) and secretariat support form meeting arrangements, notes and actions

Good Practice Tips

Theme 2: SDS and Local Plan Interaction

The relationship between emerging Spatial Development Strategies and Local Plans is critical, particularly when they are being prepared concurrently. Some of the key issues identified were the need to support Local Plan soundness (reducing risk of Local Plan departure from emerging SDS) such as identifying housing needs, considering spatial options and major infrastructure locations at an early stage.

Theme 3: Data, Evidence and Digital Tools

The focus of this theme is the practicalities of evidence base and preparation, data and digital working through the lens of cross authority working.


Near-universal themes were the need for: 

  • Better digital infrastructure
  • Shared databases and evidence
  • Joint evidence procurement


There was a wide variance between areas in maturity and digital confidence.

Theme 4: Housing, Infrastructure and Spatial Strategy

This theme looks at key SDS policy areas through the lens of cross authority working.
Some of the challenges consistently identified in the workshops were that growth and investment need to be explained strategically and equitably, given the tensions often emerging, including:

  • Between constrained areas (e.g., Green Belt, flood zones, sea) and higher capacity growth areas
  • The perception of ‘unfair’ housing redistribution
  • Infrastructure capacity

Theme 5: SDS readiness tips for authorities going through significant change

Three of the workshops were held in areas that do not yet have a combined or strategic authority in place and will be experiencing significant change in the coming year or two – devolution, local government reorganisation (LGR) and local elections.  These areas face different challenges to areas that have existing combined authorities. These challenges to SDS preparation include:
 

  • Uncertain political leadership
  • Pressure for focus on priorities other than SDS, including Local Government Reorganisation, elections, other strategic and local issues.
  • Lack of capacity and resourcing for SDS work particularly with pressure for Local Plan preparation.
  • Lack of strategic planning skill
