Our History

Manor Marine UK Limited was formerly known as MPI Services UK Limited t/a Manor Marine. MPI Services was originally founded as a partnership in 1981 and initially concentrated on general construction work. This involved the provision of a varied range of services both on and off site with many contracts having been undertaken for well-known National construction companies.

In 1990, MPI Services founded Manor Marine, a subsidiary company with the aim of expanding the marine activities of the firm. This coincided with the return of a major ferry company restarting the UK / Channel Islands / France service. Manor Marine were awarded contracts for the refit and maintenance of these ferries. This new challenge meant additional skills and specialised equipment were required.
