How to Evaluate a Site for EV Charging Potential

Key takeaways

• Grid headroom is the first thing to check, and the one most often left until last.

• Dwell time and visitor patterns decide whether chargers will actually be used.

• Access, visibility and room to expand matter as much as the number of bays.

Start with the power you already have

Before anyone talks about charger speeds, find out what the existing grid connection can support. A site with spare capacity can go live in months; a site that needs a new connection or substation can take far longer.

A short power assessment early on gives you a realistic timeline and budget before you commit to anything else.

Look at how people use the site today

Chargers earn their keep when drivers have a reason to stay. Retail parks, leisure sites, offices and residential buildings all have natural dwell times that suit different charging speeds.

Visitor numbers, opening hours and peak periods tell you how many bays the site needs now and how quickly demand is likely to grow.

Check access, visibility and safety

Bays need to be easy to find, easy to reach and well lit. Sites where chargers sit behind barriers or in a far corner of the car park consistently see lower use.

It is also worth checking where cables can run, where equipment can be housed and whether there is room to add more bays later without digging the site up twice.

Get a second opinion before you commit

We assess every site before we propose anything, and we are open about sites that are not a good fit. A clear-eyed evaluation up front is far cheaper than a charging hub that never reaches its potential.
