Part S help from the people who helped write it

All new residential developments must comply with Part S Building Regulations to provide EV charging. Installing EV infrastructure in shared car parks comes with unique challenges, from managing power capacity to compliance sign-off, that can quickly increase development costs.

Cosmic helps you solve those at the design stage, before they become expensive site problems. We've saved 30–70% on installation costs through design alone. Done well, it's not just cost avoided — it's charging residents use, and value added to your development.

Our founders helped shape Part S during the Building Regulations consultation and continue to be involved in the statutory review, so you'll be working with people who know the regulation inside out.


“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.”

Ramon Seera, Head of Technical at Dorchester Group

Design decisions that cut your costs

By addressing the specific needs of shared parking environments at design stage, developers can 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.

Any hardware, any installer

Use our installation team or your own. We're charger-agnostic, so the design works with your preferred supplier.

Ongoing management

Start with a free concept design

Not ready to commit to a full project? We'll produce a free, no-obligation concept design, so you can see what's possible. We're hardware agnostic, so this works with your preferred suppliers, not just ours.

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.
3D model of a multi-level parking garage with several cars parked inside.
Electrical plan for proposed electric vehicle charging point at St. James Place, showing wiring, cable layout, and EV distribution board layout at 20 Abbey Road.
