Elliott Fletcher of Managementors warns that Local Government Reorganisation will only deliver its promised savings if councils tackle operational change head-on — not just structural change — or risk carrying today's inefficiencies straight into tomorrow's unitary authorities.

Local Government Reorganisation (LGR) is being positioned as a solution to widening financial gaps, fragmented service delivery and growing demand pressures. Business cases point to material savings from management delayering, service rationalisation, economies of scale and stronger strategic leadership. Those benefits are achievable.

The problem is that most councils are not operationally ready to make them real.

As Professor Steven Broomhead MBE, former Chief Executive of Warrington Borough Council, puts it: ‘There is a danger that existing inefficiencies could simply be carried over into the new unitary authorities, rather than being addressed before integration. To avoid this, it is crucial that services and corporate teams are reimagined from first principles, ensuring that today's performance issues are not built into tomorrow's structures.’

The hidden assumption in most LGR business cases

Most LGR business cases assume headline savings in four areas: a 5–15% reduction in management and support costs; economies of scale across services; improved productivity from service integration; and stronger local leadership decisions.

Our experience shows that every one of those savings depends on operational change, not structural change alone. They rely on redesigning workflows, changing roles and spans of control, improving productivity and quality, and reducing rework and failure demand.

In practice, most LGR programmes are framed as structural reorganisations, governance and TUPE exercises, and systems and programme management initiatives. Very few are underpinned by detailed service-level operating model redesign, activity and skills analysis, or capacity and productivity modelling. Without a data-led, evidence-driven understanding of how services actually run today, projected savings remain assumptions rather than deliverable plans.

The operational risks councils must not ignore

Assumed savings without a service-level plan

Headline savings targets are often not translated into service-level plans. Research across the industry has shown that splitting county councils into multiple authorities as small as 300,000–400,000 residents could result in additional costs in the hundreds of millions every year for local taxpayers. This being particularly true where management scale and specialist capabilities are diluted. Savings do not materialise because the underlying operating model has not changed.

Live service degrades as integration happens

Services are expected to merge while continuing to manage live demand. As integration ramps up, focus shifts to combining services with different case management models, different productivity levels, and different cultures and performance disciplines. This will stretch the bandwidth available to resolve existing issues in underperforming areas. Evidence indicates that breaking up high-performing county councils into substantially smaller ones could lead to a degradation in services, particularly in children's care, where larger authorities are significantly more likely to receive Outstanding or Good Ofsted ratings.

Cost reduction undermines service resilience

The pressure to demonstrate early savings can drive rapid rightsizing. Premature hiring freezes or consultations can be at the expense of service, creating backlogs and reputational risk. Reducing cost before stabilising performance increases risk precisely when resilience is most needed.

What successful transitions do differently

Stabilise critical services early. High-risk, high-cost services, Adult Social Care, for example, must be stabilised before integration begins. Having control of a service requires a clear understanding of true demand, current work in progress and available supply. Without it, dropping performance during transition is almost inevitable.

Design the future operating model bottom-up. Successful transitions start from first principles: What work needs to be done? How should it be done, and by whom? How is success measured? Are key activities better delivered in-house, outsourced or through a blended approach? The outcome should be a deliverable operating model grounded in service reality.

Have a plan to integrate in-house, shared and outsourced delivery. Combining smaller authorities often means inheriting a mix of in-house services, shared arrangements and outsourced contracts for the same service. Successful authorities create a single performance framework across all delivery models and establish clear accountability between client and service provider.

Three questions to ask before you proceed

LGR creates opportunity, but it does not deliver savings by default. Before committing to management delayering, role reductions or service consolidation, councils should ask:

1. Do we truly understand how our services perform today? Do we have reliable data on demand, capacity, productivity, backlogs and failure demand? Or are savings assumptions built on averages and high-level benchmarking?

2. Are our savings plans operationally deliverable? Have headline targets been translated into role redesign, workflow change and clear productivity improvements at service level?

3. Where are our resilience risks during transition? Which services cannot afford a performance dip? Where would regulatory failure, backlog growth or workforce attrition create unacceptable risk?

Councils that approach reorganisation with operational discipline grounded in real data on demand, capacity, skills and productivity are far more likely to realise savings while protecting service quality.
