simPRO enables us to manage & record full maintenance records of all task completion against individual assets, all of which will be preloaded at the contract mobilisation stage.

With simPRO we schedule all PPM tasks including sub-contractor visits with a live feed back to the site team, site supervisor & contract manager for completion of tasks.

All quotes are raised, tracked & issued via simPRO & if required are available to the client through their personalised customer portal.


The system automatically generates an ‘action’ for any non-conformance that is reported as well as identified faults & health & safety concerns, i.e. near miss reporting.

The customer portal provides instant online access to service & asset management information, as well as to business critical management information.


Operating from our head office in Witham, Essex we service national PPM contracts & manage projects throughout the UK.

Our reactive maintenance is delivered as far north as Peterborough & south to the coast; east to Norwich & west to Birmingham.
