What is an EV charging hub?

An EV charging hub groups chargers at one location so several vehicles can charge there. Government guidance defines a charging site as multiple nearby chargepoints [S1]. A proposal for 4 assumed 50 kW outputs totals 200 kW on paper, but shared-power limits can reduce simultaneous output. Ask for an explicit site power design. Checked October 2026.

What is a charging hub?

An electric vehicle charging hub is a group of chargers at a shared location, planned for several vehicles to use. Government guidance calls multiple chargepoints in close proximity a charging site [S1]. The hub label alone does not describe its available power or layout.

For your site, ask the developer to show charging positions, vehicle circulation and power allocation. Compare destination and en-route charging to establish whether visitors are stopping to charge or charging while they visit.

How much power does a hub need?

An illustration, not a quote: assume four outputs are each rated at 50 kilowatts (kW), a measure of power. Their combined rated output is 4 × 50 = 200 kW. If the design shares a 100 kW output limit equally between four occupied bays, each would receive 100 ÷ 4 = 25 kW in this simplified example.

Those assumptions do not specify the required grid connection: equipment losses and other site loads also need assessment. Ask for the simultaneous charging capacity and the effect on existing building loads.

A distribution network operator (DNO) runs the local electricity distribution network. Government guidance explains how to approach connection planning, including assessing requirements and considering flexibility [S2]. Read the DNO application guide.

What does a hub proposal mean for your car park?

Request a drawing showing the bays affected, access hours, signage, accessible routes and any proposed electrical compound. Ask your council which planning approvals the specific design needs, and have your solicitor review land rights, liability and exit obligations.

Do not estimate host income from charger count alone. Ask for a usage-based forecast, the tariff assumptions and all deductions. Use the host agreement checklist to compare responsibilities before committing space.
