Overheating (CIBSE TM52/TM59 metrics), surface-water and fluvial flooding, water-supply stress in eastern regions, and storm-driven roof and tree-safety risks. The UK Climate Change Risk Assessment is the back-stop reference.

TM52 sets the limits of thermal comfort in classrooms; TM59 covers bedrooms (less relevant for schools but useful for residential boarding). Most secondary classrooms in southern England fail TM52 in design summers from 2030 onward without intervention.
Fabric upgrade (reduced solar gain via external shading, insulation), MVHR (filtered fresh air with summer-bypass), and tree planting (shade plus biodiversity) all deliver both adaptation and decarbonisation benefit.
A typical secondary should budget £50k to £200k for adaptation works (overheating mitigation, SuDS), depending on building exposure. Pre-1944 stock with limited shading typically lands at the upper end.
