The Hidden Costs of Poor Indoor Signal at EV Charging Points

As electric vehicle (EV) adoption continues to grow across the UK, charging stations have become critical infrastructure and with that comes the need for reliable mobile connectivity. Unfortunately, many EV charging points located in underground car parks, multi-storey garages or remote areas suffer from weak or non-existent indoor signal. While it may seem like a minor inconvenience, the consequences can be far-reaching.

1. Failed Transactions and Lost Revenue

Most EV charging stations rely on mobile data connections for processing payments. Poor signal can cause card readers or mobile apps to time out, leaving users unable to complete their charge. This not only results in lost income, but also affects user trust and satisfaction.

2. Frustrated Drivers and Negative Reviews

EV drivers expect seamless functionality. If your site struggles with signal dropouts or app errors, frustration builds quickly, often resulting in negative online reviews or social media complaints. These can damage the reputation of your brand or facility, especially if competitors offer a more reliable experience.

3. Missed Alerts and Maintenance Issues

Many modern charging systems are monitored remotely via cloud-based platforms. Weak signal can delay or block critical alerts and diagnostics, increasing the time it takes to resolve faults. Unresolved issues can lead to longer downtimes and lost footfall.

4. Compromised Safety and Connectivity

Poor mobile coverage also presents a safety concern. Drivers unable to make calls or access emergency services are placed at unnecessary risk — especially in enclosed or poorly lit areas like underground car parks.
