Annual Local Authority Road Maintenance (ALARM) survey

Annual Local Authority Road Maintenance (ALARM) Survey Report

2024 survey highlights challenges ahead for local roads

Every year the Asphalt Industry Alliance (AIA) commissions an independent survey of local authority highway departments in England (including London) and Wales.

The Annual Local Authority Road Maintenance (ALARM) survey report provides detailed insight into the funding and conditions of the local road network, based on information provided directly by those responsible for its maintenance. Submissions received from more than 70% of local authorities in England and Wales, provide robust findings which are used by stakeholders across the sector for tracking, benchmarking and planning purposes.

ALARM 2024 data shows that more than half the local road network is reported as having 15 years or less of structural life remaining, and that £16.3 billion is now needed to tackle the backlog of carriageway repairs in England and Wales – the highest figure in 29 years of reporting.
