All motorway maintenance contracts are awarded by competitive tender to contractors whose staff hold the relevant safety, quality and environmental accreditations. Most contracts include an annual lump sum which is designed to cover minor maintenance work such as hedge-cutting and fence repairs. Under some older contracts fence and hedge maintenance is procured by issuing works packages of varying sizes. The Highways Agency has specific standards for landscaping work of this type to which its agents, who manage the contract, are expected to conform. In addition, Highways Agency staff carry out periodic inspections to check the general condition of the network, where any problems with the standard of fence and hedge maintenance would be identified.
