How we help

1) Design - compliance achieved often at 50% of the cost

2) Supply - we typically achieve very good value on hardware

3) Install - outsource to Cosmic or deliver with your incumbent team

4) Adopt - we operate the system from day one

We recently worked with Cosmic Charging on a Part S compliant EV charging strategy, and the experience was excellent from start to finish. Their knowledge of the regulations and practical requirements was clear at every stage of the project.

We would highly recommend them for EV infrastructure planning and Part S compliance support.

Why EV charging is complex for shared parking?

Installing EV chargers is straightforward when parking sits next to a house.

In shared parking areas, such as apartment car parks, underground parking or courtyards, systems become more complex. Power must be shared, load managed, billing implemented and the system maintained long-term.

Cosmic designs these systems to work from the start.

What does this mean for shared parking areas, underground car parks and courtyards?

Shared parking areas introduce additional complexity because electrical capacity must be shared, equitable billing systems must be in place, and the system must be maintained and remain safe over time.

At design stage, developers need to consider these factors to avoid costly changes later:

Ongoing management

Who will manage, maintain and support the system after handover.

Adoption, Management
and Maintenance

  • Resident onboarding

  • Billing and payment collection

  • Load management software

  • Maintenance and repairs

  • Resident support

  • Ongoing system management

  • System monitoring and safety checks

Developers can complete and hand over the site knowing the EV charging infrastructure is compliant, operational and managed for the long term, without adding to the service charge or responsibility to the managing agent.

Examples of the drawings, layouts and specifications we typically produce:

A detailed site plan for a residential community showing electrical and EV charging infrastructure, including parking bays, electrical feeders, EV chargers, and key legend symbols for various electrical components.
