For construction, two transmission routes matter most. First, developer and contractor borrowing: the effective rate on new loans to UK private non-financial corporations had fallen from a 2024 peak of 7.26% to around 5.66% by February 2026 – a partial reprieve that had been baked into project financial models. That reprieve has now been eroded, effectively reversing months of gradual easing in a matter of weeks. [...] #### Channel 1: Input Cost Inflation\n\nEnergy is a significant direct cost for construction companies – powering plant, machinery, site facilities and transport logistics. Beyond energy itself, construction’s material inputs are heavily energy-intensive to produce: cement, bricks, steel, aluminium and glass all require substantial energy to manufacture, meaning that sustained energy price elevation feeds through into the cost of primary materials with a lag of weeks to months.",
