    What our clients say

    Connect Plus Services M25 Dartford Crossing

    ‘Even a short closure of the tunnel causes great congestion in the area, and if an over height vehicle were to cause that level of damage, the tunnel could be closed for hours, if not days, which would bring the whole of the South East of England to a standstill.

    When the Coeval over height vehicle detectors were first installed, we were talking about 10’s of vehicles a day that we were stopping; we are now down to low single figures, 4 or 5 vehicles a day we need to extract for being over height, so it’s a great improvement in efficiency through the crossing.’

    Platinum Electrical Ltd

    ‘Having used Coeval for the first time, we found them to be friendly and really helpful in ensuring we received the correct item we required. We were happy with the extremely quick response times and professional service they offer. We would definitely recommend their services to others.’
