Poor Data, Costly Consequences
Why weak estate intelligence continues to undermine investment, increase risk and leave schools paying the price
For more than a decade, the Department for Education has commissioned successive national condition surveys across England’s school estate, covering some 22,000 schools. The Property Data Survey Programme (PDSP) ran from 2012 to 2014, followed by two rounds of the Condition Data Collection between 2017 and 2026. In principle, this should have created a robust evidence base for investment decisions, long-term planning and informed stewardship of one of the nation’s largest public estates.
In practice, it has fallen short.
Following the National Audit Office 2023 report, Condition of School Buildings, there was clear recognition that previous data exercises had not gone far enough. Future templates were expected to capture richer, more useful information and address known shortcomings in methodology and scope. Yet events soon overtook that ambition.
The Reinforced Autoclaved Aerated Concrete (RAAC) crisis exposed a fundamental weakness in the approach. Governments had long been aware of the risks associated with RAAC in public buildings, yet identifying its presence had not formed part of the scope of the PDSP, CDC1 or CDC2 programmes. A material risk sitting within the fabric of the estate had remained largely invisible because the system was not designed to look for it.
That is the danger of high-level data collection.
The central criticism of each survey has been consistent: they were too superficial to provide the depth of intelligence required by schools, the DfE or the Treasury. Where inspections rely primarily on visual assessments and limited access, outcomes will inevitably appear more favourable than reality. Deeper, more intrusive investigations uncover hidden defects, latent liabilities and the true scale of backlog need. Without that, condition gradings become optimistic, priorities are distorted and risk is understated.
The consequences extend far beyond spreadsheets.
When the condition of the estate is underestimated, so too is the case for investment. Funding bids to the Treasury are based on incomplete evidence, and the sector is left competing for resources without a full account of its needs. This has created a painful legacy: years of underinvestment, rising deterioration and growing pressure on already stretched budgets.
Only in recent years has there been widespread public and political recognition of the age and fragility of the school estate. RAAC may have been the trigger, but it is far from the whole story. Across the country, schools are dealing with life-expired assets, compliance pressures, energy inefficiency and mounting maintenance liabilities. At the same time, responsibility for managing much of that risk sits squarely with the responsible body.
“if decision-makers still lack sufficiently accurate condition and cost data, how can resources ever be allocated with confidence or fairness”?
The current policy response has been to continue the School Rebuilding Programme, first launched in 2020. It is a significant initiative, but it is also a selective one. With only a limited number of schools benefiting directly, the vast majority must continue to manage their estates through constrained capital allocations and local decision-making. At the present pace, the programme risks becoming a long-term pipeline rather than a near-term solution.
That raises an uncomfortable question: if decision-makers still lack sufficiently accurate condition and cost data, how can resources ever be allocated with confidence or fairness?
For schools and trusts, the lesson is clear. They cannot rely solely on central datasets or await the next national survey. In an increasingly competitive environment, where organisations compete for funding, staff, pupils and opportunity, estate intelligence has become a strategic asset. Independent condition surveys, compliance reviews, sufficiency assessments and energy data are no longer optional extras. They are the foundation of sound investment decisions.
This is especially true as expectations evolve. Schools are now expected to hold Climate Action Plans and many are exploring decarbonisation strategies, including the transition away from gas-based infrastructure. New funding and delivery models such as serviced managed leases and power purchase agreements may offer practical routes forward, but they depend on credible data. Whether for governance assurance, lender scrutiny or board approval, the numbers must stand up and the evidence must be robust.
Many schools do not have the internal capacity, time or specialist expertise to do this alone. Estate management and procurement are rarely core competencies, yet they have never been more important.
That is where expert support can make the difference. Warneford Consulting, through Great Estate Management Zero (GEMZ), provides a complete service spanning data capture, estate strategy, bid development, compliant procurement and project delivery for schools, trusts and responsible bodies of every size and structure.
Because better decisions start with better data.
