[...] ### Cost pressures\n\nCost pressures are easing compared with the 2022–23 shock, but inflation hasn’t gone away: BCIS and market trackers point to milder cost growth into 2026, while ONS output data through late-2025 showed uneven month to month movement, so prelim control still matters. \n\nAdding in tax rises, wage inflation and ongoing material cost volatility, and margins will remain tight for contractors of all sizes in 2026. Strong cash-flow control and proactive risk management will remain critical. \n\nThat said, businesses that use technology to replace lengthy manual processes such as risk assessment and method statements (RAMS), can significantly reduce administrative time and minimise avoidable risks that lead to delays or cost overruns, helping to offset some of these pressures.
