Context
Why The First 100 Days Matter
The first 100 days of a new unitary authority are critical. This is when governance structures are established, planning systems are integrated, and political relationships are formed. Evidence from recent reorganisations shows that decisions made during this period have lasting impacts on authority performance, democratic accountability, and service delivery.
Critical Window
Authorities that fail to establish clear governance and planning frameworks in the first 100 days face significantly higher risks of performance decline, political instability, and service disruption.
The framework
Key Priorities
Establish Governance Framework
Set clear decision-making structures, committee systems, and delegations. Evidence shows that authorities with well-defined governance from day one experience fewer political conflicts and faster decision-making.
Integrate Planning Systems
Merge planning teams, harmonize processes, and establish unified development management. Delays in planning integration are consistently linked to performance decline in the first year.
Build Political Cohesion
Create mechanisms for cross-party engagement and manage expectations around service levels and financial constraints. Political fragmentation during transition increases risk of strategic drift.
Secure Financial Controls
Establish unified financial systems, budget monitoring, and reserves management. Early financial control failures can lead to Section 114 notices within the first two years.
Evidence
Evidence From Recent Transitions
Analysis of recent unitary transitions reveals consistent patterns:
Authorities with clear 100-day plans experienced 40% fewer governance disputes in their first year.
Early planning integration correlated with sustained performance in development management.
Delayed financial system integration increased audit findings by 60%.
Development
The First 100 Days: A Playbook for Unitary Transition — Development in Progress
The First 100 Days Playbook is currently in active development.
It is being designed as a practical, evidence-informed framework to support councillors, senior officers and transition teams through the first 100 days following vesting day under Local Government Reorganisation.
The final publication will provide:
- A structured week-by-week governance and delivery framework
- Defined decision gateways and sequencing guidance
- Risk indicators drawn from recent reorganisation experience
- Practical tools for political cohesion, planning integration and financial control
- A monitoring structure to track transition stability
However, this is not being written in isolation. It is being built through structured engagement with those who have led, scrutinised or experienced reorganisation first hand. We are now entering the evidence gathering and consultation phase.
Your experience
Why We Are Inviting Contributions
The first 100 days after vesting day determine the operational credibility and political stability of a new authority.
Evidence from recent transitions shows consistent patterns:
- Early clarity in governance design reduces political conflict and accelerates decision making
- Delays in planning system integration correlate with service performance decline
- Weak financial consolidation increases the risk of audit challenge and Section 114 notices
- Political fragmentation during transition increases reputational exposure
The Playbook must therefore reflect real operational experience rather than theoretical design.
We are inviting contributions from those who have:
- Served as councillors during reorganisation
- Held senior officer roles in transition teams
- Worked within programme management or integration boards
- Observed reorganisation through audit, scrutiny or external advisory roles
- Represented communities navigating governance change
Our intention is to capture what worked, what failed, and what was underestimated.
Four evidence streams
Research Architecture
The Playbook is being developed through four structured evidence streams.
Structured Questionnaire Programme
A detailed questionnaire is being prepared for circulation to:
- Elected Members from newly formed unitary authorities
- Chief Executives and statutory officers
- Programme directors and transition leads
- Scrutiny chairs and audit committee members
The questionnaire will focus on:
- Governance Design — timing of constitutional adoption, committee system configuration, delegation structures, cabinet and scrutiny balance
- Planning Integration — system harmonisation, case backlog management, Local Plan continuity, development management performance
- Financial Consolidation — budget alignment, reserves management, financial systems integration, early warning indicators
- Political Cohesion — cross party engagement, member induction, expectation management, media and reputational risk
Participation will be invited shortly. Details of how to contribute will be published on this site and through direct outreach.
Structured Interviews
In depth interviews are being undertaken with selected individuals who have held senior roles during reorganisation. These interviews are designed to explore:
- Decisions that appeared minor at the time but later proved pivotal
- Governance sequencing errors
- Political tensions that were not visible publicly
- Financial or planning integration risks that escalated
- Lessons that would change the first 90 days if repeated
A further round of interviews will be opened shortly. Expressions of interest will be invited in the coming weeks.
Roundtable Events
A series of small, policy focused roundtables will be convened. These sessions will examine:
- The first 30 days: governance establishment
- The first 60 days: service integration and systems
- The first 90 days: political stabilisation and scrutiny maturity
- Risk management frameworks for new unitaries
- AI governance and digital system integration during transition
These will not be promotional events. They will be structured working sessions, Chatham House where appropriate, designed to test assumptions and refine the framework. Event dates and participation details will be announced shortly.
Data and Performance Review
Alongside qualitative evidence, we are reviewing:
- Audit findings from recent reorganisations
- Section 114 triggers and financial intervention cases
- Planning performance data pre and post vesting
- Governance dispute records where publicly available
This quantitative strand will ensure the Playbook is grounded in measurable outcomes rather than anecdote.

Publication Timeline
The full Playbook will be released in Spring.
Ahead of publication we will:
- Share emerging themes and interim findings
- Publish selected evidence summaries
- Announce event dates and participation details
- Provide opportunities for review and challenge
This is intended to be a practical tool for those leading reorganisation in real time. It will be shaped by those who have lived it.
