Refurbishments and Upgrades

If your current vehicle needs a revamp and / or re-work, we can repair / refurbish all types of commercial vehicles.

CMGS can also build new or retrofit battery storage solutions to upgrade your fleet to hybrid.  Fitting batteries will reduce generator running times and significantly reduce fuel and service bills as well as emissions.

Bespoke designs

CMGS offers both electrical and mechanical bespoke designs to suit customers’ needs.

 

Our clients are welcome to be fully involved in the design process to ensure the product meets their needs and expectations.
