The strategic guide for councils: Procuring, building or reviewing your in-house SEND banding tool

A decision guide for local authorities: build, buy, or update your SEND banding and EHCP tooling.
SEND Insights

Local authorities (councils) reviewing their current banding model – or deciding whether to build or buy a new tool – can use this guide to explore the right path. This guide explains procurement trade-offs, the impact on Education, Health and Care Plan (EHCP) workflow, the benefits of benchmarking, and where AI adds value – drawing on outcomes like 1% funding accuracy, reduced admin time, and an increase in the likelihood of meeting EHCP deadlines.

When should councils upgrade an in-house banding tool instead of rebuilding?

If you already operate a local banding tool or matrix, start with a quick banding health check before committing to a rebuild or procurement. Look for:

  • Accuracy drift: Are allocations diverging from actual spend by more than 1-2%?
  • EHCP performance: Has the tool helped 20-week compliance and reduced disputes?
  • Model freshness: Are descriptors, thresholds and top-up rates aligned to current need?
  • Explainability: Can panels produce clear, defensible rationales quickly?
  • Benchmarking: Can you compare band distributions and funding patterns with peers?

If two or more areas raise concern, an upgrade/recalibration or procuring an alternative tool could deliver value in weeks, avoids a long rebuild, and preserves local control.

If you’re not sure, why not book a banding health check with one of our SEND experts to assess your upgrade/rebuild options?

Should councils build or buy a SEND banding tool?

With SEND caseloads at record levels and government reforms reshaping the landscape, many councils are questioning whether their current funding approach is fit for purpose. Should you build a bespoke banding tool, purchase an existing solution, or stick with what you have?

The answer isn't straightforward – but the costs of getting it wrong are significant.


When councils consider building their own banding tools, the initial appeal is obvious: complete control, tailored to local needs, no ongoing licence fees. But scratch beneath the surface, and a different picture emerges.

Development typically takes 12-24 months minimum, requiring dedicated senior staff time that's already stretched thin. Many councils underestimate the complexity involved – what appears to be a straightforward banding exercise often becomes an extended process of stakeholder consultation, technical development, and iterative refinement before any real cases can be processed.

Maintenance & upgrades Continuous internal effort. Included in licence.
3-year total cost Often underestimated. Predictable, with local flexibility.
Return on investment Unclear, difficult to quantify until proven. Significant savings in preventative spend including £3m for every 1k cases.
Risk level Extremely high. Low (proven success, dedicated support).

After initial development

The true cost extends beyond development. Internal teams must maintain the system, respond to changing regulations, and continuously refine the model based on outcomes – all while managing day-to-day SEND pressures.

More critically, in-house tools exist in isolation. Without benchmarking data or peer learning opportunities, councils risk developing funding models that drift from best practice or fail to adapt to emerging needs.



Not all banding tools are created equal. The gap between basic functionality and transformative impact often comes down to several critical factors that councils should evaluate when considering their options.

For councils upgrading an in-house tool, look for platforms like Funding Genie that import your current descriptors and rates, support guided recalibration, and deliver benchmarking without losing local policy control.

The hallmarks of truly effective banding solutions include:

  • Proven accuracy at scale: The best solutions demonstrate consistent precision across thousands of cases. Look for tools that can show variance rates of 1% or less between estimated and actual funding when properly calibrated – this level of accuracy transforms estimates into reliable budget planning.
  • Documented operational improvements: Effective platforms deliver measurable gains: increased EHCP deadline compliance, demonstrable return on investment, and reduced disputes. These outcomes matter because they're what senior leadership and scrutiny committees evaluate success against.
  • Practitioner-led development: Solutions developed through genuine collaboration with case officers, panel members and finance leads tend to address real workflow challenges rather than theoretical problems. This collaborative approach typically results in features that land where they're genuinely needed.
  • Built-in transparency and defensibility: The strongest tools incorporate structured needs assessment, automated rationale generation and quality checks that reduce ambiguity while building stakeholder confidence – including with parents and carers.
  • Adaptive and future-ready architecture: Leading solutions evolve continuously, reflecting regulatory changes and emerging best practice. The most advanced now include AI capabilities that accelerate document analysis and decision support while preserving professional judgement.
  • Benchmarking and peer insights: Access to anonymised cross-authority data enables councils to understand their funding patterns in context, informing both policy development and strategic commissioning decisions.
  • Comprehensive implementation support: Successful deployments typically involve structured rollout pathways with defined success criteria, configuration support, training resources, and ongoing performance review processes.
  • Robust security and compliance: Essential requirements include UK-based hosting, appropriate encryption, compliant data handling, and alignment with current Data Protection Act 2018 regulations.

These characteristics reflect the current state of the art in SEND banding technology. Solutions like Imosphere's Funding Genie – a 5th-generation SEND banding platform for councils – delivers 1% funding accuracy, cross-authority benchmarking, AI-assisted EHCP summarisation and rationale generation, and UK-hosted (Azure) infrastructure aligned with UK GDPR and the Data Protection Act 2018. It shows what’s achievable when these capabilities work together at scale.



While AI promises to revolutionise SEND processes, implementation matters enormously. The difference between transformative and disappointing lies in how technology supports rather than replaces professional judgement.

Leading-edge AI capabilities now enable:

  • Instant EHCP summarisation that highlights key needs and provision requirements
  • Automated quality checks that flag inconsistencies before they reach panel
  • Evidence-based rationale generation that creates defensible funding justifications in seconds

But here’s the crucial point: effective AI should augment professional expertise rather than replace it. The best systems ensure decision-making responsibility is retained by practitioners while eliminating administrative burden.

That’s exactly how Funding Genie is engineered. AI that does the heavy lifting (summarising, checking, drafting) while practitioners stay firmly in control, backed by a clear audit trail and outcomes councils can defend.



Smart councils are looking beyond standalone banding tools toward integrated SEND management platforms. When banding works seamlessly with EHCP drafting, review processes, and analytics, the compound benefits are significant:

  • Reduced duplication across different stages of the SEND journey
  • Consistent data that enables meaningful trend analysis and forecasting
  • Streamlined workflows that help teams focus on children rather than systems

That’s the design principle behind the modular SEND Genie Toolkit: Funding Genie for defensible banding, paired with EHCP Genie for drafting, review, and analytics modules that share one data model – so decisions, documents, and dashboards stay in sync from first referral to annual review. Each module can be purchased standalone or bundled, and they interoperate out of the box. In short: one toolkit, one source of truth, better outcomes.



Councils using established banding solutions should be able to report measurable improvements. For example, Imosphere’s partner councils are benefiting from:

  • 25% increase in likelihood of meeting EHCP deadlines
  • Reduction in administrative time for funding decisions
  • Significant decrease in funding disputes and appeals
  • Enhanced stakeholder confidence in decision-making

These aren't marketing claims – they're documented outcomes from councils facing the same nationwide pressures you are.


Making the right choice for your council

Whether you build, buy, or adapt existing approaches, several factors should guide your decision:

  • Timeline pressures: Can you afford 12-24 months (minimum) of development while caseloads continue rising?
  • Resource availability: Do you have the specialist skills and capacity for ongoing maintenance?
  • Risk tolerance: How comfortable are you with unproven approaches when statutory deadlines loom?
  • Stakeholder expectations: Can you maintain confidence while developing new systems?
  • Post-upgrade gains: Improved accuracy after recalibration and faster panel sign-off with clearer rationales.

The most successful implementations often involve councils that choose proven solutions, then configured them to reflect local priorities and approaches. This hybrid model delivers the benefits of established platforms while maintaining local control over key decisions.

That’s why Imosphere provides off-the-shelf, proven solutions that are then tailored to each council’s local descriptors, funding rates, workflows, and reporting needs. You get rapid time-to-value and lower delivery risk, without sacrificing local control or governance.

What's next?

The SEND landscape continues evolving rapidly. Government reforms, changing needs profiles, and rising demand all point toward more sophisticated funding approaches. The question isn't whether change is coming – it's whether your tools will help you navigate it successfully.
