Approved Document S compliant designs

EV infrastructure designed for compliance, cost and long-term operation.

What we do

Cosmic designs Approved Document S compliant EV charging infrastructure for residential developments. We produce designs, specifications and equipment schedules, and value engineer installations to reduce construction costs (typically saving 50% of infrastructure costs).

After practical completion, we adopt, manage and maintain EV infrastructure in shared parking areas. We provide billing, software and maintenance so the system remains operational long-term, without adding cost or responsibility to the managing agent.

Our expertise

  • Consulted on 100s of EV charging projects

  • Worked with HBF on Part S guidance

  • Senior team with 30+ years combined experience

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:

Electrical capacity

How to provide enough power for a working system without triggering unnecessary grid upgrade costs.

Value engineering

How to reduce installation costs through the right design and equipment choices.

Part S compliance

How to ensure the installation meets Approved Document S requirements from day one.

Ongoing management

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

Adoption, Management
and Maintenance

Cosmic can adopt the EV charging infrastructure after completion and take responsibility for operating the system in shared parking areas.

We provide:

  • 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.
