According to the public spending watchdog, the increasing backlog in road maintenance work hinders local authorities in undertaking preventative work that could deliver better value for money.
The Department for Transport (DfT), it appears, does not even know how bad things have got because it doesn鈥檛 want to overburden local councils by demanding complete data from them.
The National Audit Office (NAO) report, The condition and maintenance of local roads in England*, states: 鈥淒espite their importance, the condition of local roads is declining and the backlog to return them to a good state of repair is increasing.
鈥淒fT has provided between 拢1.1bn and 拢1.6bn of capital funding each year to local authorities and has set out plans for additional funding through to 2034. Given the fiscal constraints, it is essential that DfT secures maximum value from the funding it has available.
鈥淗owever, at present DfT does not have a good enough understanding of the condition of local roads, and does not use the limited data it does have to allocate its funding as effectively as possible. It does not know whether the funds it allocates are delivering improvements in road condition, and has not updated its guidance to local authorities, to share good practice and help them make the most of their limited funds, for some years.
鈥淢anaging the local road network is becoming increasingly complex 鈥� for example, as climate change and autonomous vehicles demand more from it 鈥� and the additional funding that DfT has secured provides an opportunity to equip local authorities to better meet these challenges.
鈥淚f DfT is able to address the issues in its current approach, it will be much better placed to improve the value for money of funding in this area and secure an improved and more resilient local roads network.鈥�
In 2019 the Department for Transport (DfT) estimated the cost to address the backlog in local road maintenance as between 拢7.6bn and 拢11.7bn. In 2023/24, industry estimates put the backlog at 拢15.6bn, based on a long-running Asphalt Industry Alliance survey of local authorities.
According to the NAO: 鈥淭here are currently significant gaps in DfT鈥檚 information on the condition of local roads, limiting its understanding of condition of the network. DfT requires local authorities to report the proportion of their road networks that should be considered for maintenance each year, based on a survey of a portion of the network. Local authorities do not provide all the data that DfT mandates 鈥� for example, one fifth of authorities did not share data on the proportion of their A roads that should be considered for maintenance in 2023. DfT plans to increase the response rate of local authorities by working with them more closely and recruiting a dedicated DfT specialist for road condition data collection. There is no reporting requirement for unclassified roads, which make up 62% of the local network, although around 70% of local authorities provided these data in 2023. This means DfT does not hold information for much of the network. DfT told us that it decided to limit the data it collects from local authorities to minimise administrative burdens (for local authorities).鈥�
The limited data that DfT does collect show the surface condition of local roads as stable over time, but information from industry bodies and people using roads suggests that road condition is getting worse, the NAO says.
鈥淒fT鈥檚 latest data on road surface condition show that around two-thirds (67% in 2022-23) of total local road network length was in good condition. However, a long-running survey of local authorities by the Asphalt Industry Alliance shows only half of roads (48% in 2023/24) to be in good structural condition, and that this has been largely consistent since 2015/16. Research undertaken in 2021 by the UK Roads Leadership Group 鈥� a body chaired by DfT, but whose members come from national and local government 鈥� found the condition of the network was deteriorating.鈥�
Recommendations made by the NAO to the DfT include:
- Review its approach to allocating capital funding to local authorities for local road maintenance to ensure its allocative effectiveness.
- Work with the Treasury to set out how it will provide longer-term funding certainty to local authorities that will help better support preventative road maintenance approaches.
- Update its use of incentivised funding and consider how it could use this to improve outcomes.
Responding to the report, Asphalt Industry Alliance chair David Giles said: 鈥淭he results of the National Audit Office report clearly echo those of our Annual Local Authority Road Maintenance (ALARM) survey reports across the years and confirm what we already know 鈥� the condition of our local roads is now at an all-time low and there are significant challenges ahead if we are to see significant improvements.
鈥淭he report consistently refers to the results of our ALARM survey, highlighting its importance as a credible source of data, and the AIA welcomed the opportunity to provide information for review in this process.
鈥淭he NAO report makes some strong recommendations for how the DfT can help improve its understanding of the condition of the network in England, its approach to funding and its support and guidance for local authorities to help them deliver effective and efficient highways maintenance.
鈥淲e stand by the calls made in our 2024 ALARM survey report for sustained, targeted and accountable funding for local roads, which are complementary to those NAO recommendations. Without clarity on how much money will be made available over the life of this Parliament, as well as an effective ring-fence mechanism, local authorities will be unable to carry out the proactive maintenance required to improve conditions for the benefit of all road users.
鈥淪wift action needs to be taken and we look forward to working with the new ministerial team at the DfT to support efforts to improve local road conditions and address the 拢14.4bn carriageway maintenance backlog reported in England in this year鈥檚 ALARM survey.鈥�
