Are NHS Buildings Falling Apart?

The NHS maintenance backlog — the estimated cost of returning buildings to an acceptable standard — reached £13.8 billion in 2024, more than three times the £4.3 billion recorded in 2014.^[1] Over 40% of the hospital estate predates 1978. Annual NHS capital expenditure has been roughly flat in real terms over that same decade, at £5.9 billion in 2024 versus £5.8 billion in 2014, while the backlog tripled; trusts have repeatedly surrendered capital budgets mid-year to cover revenue deficits.^[3] The RAAC concrete crisis sharpened public focus: 42 trusts have confirmed the structurally unsound 1960s–80s building material in their estate, several wards have been closed at short notice, and one in four NHS buildings is now rated high-risk for infrastructure failure.^[2] NHS IT infrastructure is equally antiquated, and the Lord Darzi review estimated the true combined capital deficit across buildings, equipment, and digital systems significantly exceeds the headline ERIC figure.^[4]

The consequences fall on patients and staff across the system. Aging diagnostic equipment increases downtime and scan wait times; crumbling wards force department relocations and reduce clinical capacity. The UK spends less per capita on health capital than the OECD average — a gap that has widened over the past decade — and the NAO has repeatedly flagged concerns about data quality, meaning the true scale of decay is likely larger than the £13.8 billion headline.^[3] Building new hospitals attracts political attention; maintaining existing ones does not, and that asymmetry has compounded year after year.
