What guarantee comes with a smart EV charger installation?
There isn’t one standard guarantee for every smart charger: the equipment warranty and cover for our installation work depend on the charger and the work agreed. We set the applicable terms out in your written quotation before installation, so you know what’s covered and who to contact if a fault develops.
The guarantee for a smart EV charger installation normally has two parts: our guarantee for the installation work and the manufacturer’s warranty for the charger. The written terms explain which part applies, how long it lasts and what it excludes. That distinction matters if the charger, cable, protection or smart function develops a fault.
If the problem comes from the way we installed or commissioned the system, the installation guarantee is the relevant cover. This can include faults involving the cable route, terminations, protective devices, mounting or commissioning, provided the issue falls within the agreed terms. We investigate the fault rather than assuming the charger itself has failed.
If the charger hardware or its internal software has failed, the manufacturer’s warranty usually applies instead. We can help establish whether the equipment warranty is relevant and explain the next step. The manufacturer’s terms control that part of the claim, including any requirements for diagnostics, replacement or return.
Smart charging adds a few boundaries that a standard installation guarantee may not cover. The charger may rely on:
- the manufacturer’s app and cloud service;
- the home’s broadband or mobile connection;
- the electricity supplier’s tariff data;
- the vehicle’s charging settings; and
- third-party software or account access.
A problem with one of those services may not indicate faulty installation. We can help separate a wiring or charger fault from a connection, account, tariff or vehicle issue, but the relevant service provider may need to resolve the latter.
Guarantee cover can also exclude damage caused by impact, flooding, unauthorised alterations, incorrect use or work carried out by another contractor. It does not normally cover the vehicle, changes to the electricity supply outside the installation, or faults in unrelated household wiring. The exact exclusions appear in the quotation and guarantee terms, so you know the limits before agreeing to the work.
Your paperwork should show the installed equipment, commissioning details and the terms that apply. Keep it with the charger information, particularly if the property changes hands or another electrician later works on the electrical system. Alterations made without checking the original installation can affect the guarantee.
When you report a fault, tell us what the charger is doing, what the app shows and whether the vehicle charges from another point. We use that information to narrow down the cause. Our NICEIC and ECA electrical work follows the standards expected for domestic electrical installations, while the guarantee gives you a clear route for dealing with a problem linked to the work itself.
If you later add solar panels, a battery or extra load management, the original guarantee may not cover changes to the charger or its wiring. We can check the existing installation before any alteration and explain whether the proposed work sits within the original terms.
That check helps keep the charger’s protection, controls and records consistent. It also means you know in advance if the alteration needs separate work or updated paperwork, rather than discovering a problem when you need to make a claim.
