what we do

Connect Plus Services (CPS) operates and maintains the M25 motorway network, including all adjoining trunk and slip roads on behalf of Highways England.

The M25 is one of the busiest sections of road in the UK. It is also undoubtedly one of the most significant.

Connect Plus Services carries out routine maintenance, winter maintenance, as well as managing the whole-life requirement of the asset. We also manage the operation of the network and identify ways of reducing delays and improving journey time reliability.
