The contract that started in 1 April 2013 aims to improve consistency in the quality of works and materials used, and to minimise disruption by sharing best practice and coordinating works.

Work under the London Highways Alliance contract is divided between four area-based joint highways contractors. The agreement includes both local and TfL road maintenance and improvement works.

Over the eight years of these contracts, London boroughs and TfL could together save as much as £450m.


By the second year of the contract, 1.4 million square metres of carriageway and 200,000 square metres of footway resurfacing had been completed.

Other improvements in 2014/15 include:

  • 87,000 defects repaired
  • 13,500km of carriageway inspected under safety inspections
  • 11.6 million square metres of grass cut
  • More than 3,000 low energy street lights installed

These boroughs had joined the Alliance by the end of the second year:

How the Alliance works

The Alliance covers a wide range of services in each of the four geographical areas of London.

The flexibility to adapt to boroughs' requirements means that the contract can be used to provide a large proportion of their existing highways services, or just one element, such as street lighting.


A collaborative approach to highway management will deliver a number of improvements, including:

  • Paying the London Living Wage for employees of participating contractors
  • Providing up to 250 apprenticeships across London to help drive the Capital's economy
  • Ensuring that all vehicles meet the latest Euro emission standards
  • Standards to ensure that all vehicles exceeding 3.5 tonnes have side guards, close proximity sensors and prominent safety signage to help improve road safety for pedestrians and cyclists
  • Ensuring all contractor vehicles meet the requirements of and hold membership within the Fleet Operator Recognition Scheme
  • Encouraging the use of local small to medium sized businesses for supplies
  • Delivering best value through collaborative procurement practices, such as jointly commissioning LED low-energy lighting
  • Sharing technical expertise around areas such as lighting, structures, drainage, contract administration, Traffic Orders and event management
  • Using innovative construction techniques and new technology for utility works to reduce traffic delays. Examples include use of road plates, quick curing materials and advanced utility location methods
  • Sharing highway management systems and resources to reduce costs
  • Improving customers' experience by coordinating works across different boroughs
  • Actively seeking out continuous improvement, for example by researching customer need and experience and feeding back into the service offering
