An EV charger that's offline earns nothing, frustrates customers and damages your brand. In 2026, reliability — not hardware price — is what separates a good charging partner from a costly mistake.
Why reliability is the metric that matters
It's easy to focus on the price of the charger. But a cheap unit that's frequently out of service is the expensive option: lost charging revenue, annoyed staff and customers, and a reputation hit when an EV driver turns up to a dead bay. Uptime is the number that actually determines return. Energy Partners targets 99.8% uptime for exactly this reason.
What to look for in a charging partner
- Guaranteed uptime / SLA — ask for the figure in writing, not a vague promise.
- Proactive monitoring — faults detected and fixed remotely, often before you notice.
- OZEV-authorised installation — required to claim grants and a baseline quality marker.
- Real accreditations — e.g. MCS, NICEIC, CHAS, Constructionline, SafeContractor.
- Fully managed service — design, install, grant claim, maintenance and support under one roof.
- Warranties and clear support — know who fixes what, and how fast.
Why "fully managed" wins
Piecing together a hardware supplier, an installer, a grant consultant and a maintenance contractor creates gaps — and when a charger goes down, everyone points at someone else. A single managed partner owns the outcome: it works, it stays up, and the grant is claimed for you.

Frequently asked questions
What uptime should a commercial EV charger achieve? Look for a high, written uptime guarantee — Energy Partners targets 99.8%. Proactive monitoring is what makes high uptime achievable.
Why does a fully managed service matter? It removes the gaps between hardware, installation, grants and maintenance — one partner owns uptime and support, so problems get fixed fast.
What accreditations should an installer have? OZEV authorisation (for grants), plus recognised marks such as MCS, NICEIC, CHAS, Constructionline and SafeContractor.
The bottom line
Choose your charging partner on uptime and accountability, not just hardware price. A reliable, fully managed partner protects the revenue and reputation your chargers are meant to build.
