MyEnergi Zappi Glo Installed in Amersham

We installed a MyEnergi Zappi Glo EV charger at a property in Amersham, HP6 6UU, and the homeowner was charging their new car within five minutes of commissioning. One of our NAPIT-certified electricians carried out a free site survey first, which revealed the property already had excellent electrical infrastructure in place. The customer had a 100 amp fuse cut out, a double pole isolate, and — crucially — a new consumer unit with a dedicated RCBO already wired and ready to accept an EV charger. This meant we could move straight to installation without any consumer unit upgrades or rewiring work.

Why did this Amersham homeowner choose the MyEnergi Zappi Glo?

The Zappi Glo is a smart EV charger that lets you track energy use in real time and control charging to match solar generation or off-peak electricity rates. For homeowners in the Chilterns area who are thinking about combining EV charging with solar panel installation, the Zappi Glo's smart features make it an ideal choice. It integrates with MyEnergi's ecosystem, so if you add battery storage later, the charger can work alongside it to maximise your energy independence.

This Amersham customer wanted a charger that would give them flexibility and visibility over their charging costs. The Zappi Glo delivered exactly that.

What does a Zappi Glo installation involve at a typical Amersham property?

Our installation started with the free site survey. We assessed the cable route from the consumer unit to the driveway — a critical step for many Chilterns properties, especially Victorian and Edwardian homes in Amersham where cable runs can be long or awkward. We checked all the existing cabling and made sure everything was safe and compliant.

At this property, the main decision was how to wire the CT (current transformer) clamp. The CT clamp monitors your home's energy flow and tells the Zappi Glo how much power is available for charging. The customer preferred a hardwired CT clamp rather than a clip-on version, so we ran the CT clamp directly from the live incoming meter to the Zappi charger. This hardwired setup is more reliable and gives more accurate readings than a clip-on alternative.

Once the CT clamp was in place, we commissioned the charger and tested the full system. Everything worked perfectly. The homeowner was able to charge their car within five minutes of us finishing — a sign that the installation was clean, safe, and properly configured.

How long did the Zappi Glo installation take?

This was a straightforward installation. A standard domestic EV charger installation takes 2-4 hours, and this job fell into that window. Because the property already had a dedicated RCBO and a new consumer unit in place, we didn't need to do any electrical panel work or upgrades. We simply ran the cable, fitted the charger, wired the CT clamp, and commissioned the system.

We managed to return the next day after the initial survey, which meant the homeowner wasn't left without charging capability for long. As soon as we switched the charger on, they were able to charge their new car immediately.

What made this Amersham installation straightforward?

Three things worked in our favour:

First, the property had modern electrical infrastructure already in place. The 100 amp fuse cut out, double pole isolate, and new consumer unit with a pre-installed dedicated RCBO meant we didn't need to negotiate with UK Power Networks (the Distribution Network Operator for the Chilterns area) for a connection upgrade. Many properties in HP postcodes are seeing increased demand for EV chargers, and upgrades can add time and cost to a project. This property was ready to go.

Second, the customer knew exactly what they wanted. They chose the hardwired CT clamp setup from the start, which simplified our planning and meant no delays or rework.

Third, the cable route from the consumer unit to the charger location was straightforward. In some Chilterns homes, especially those in the Area of Outstanding Natural Beauty, we need to plan cable routes carefully to avoid visible external runs or to check permitted development rights. This property didn't present those challenges.

Is the MyEnergi Zappi Glo the right choice for an Amersham home?

If you're an EV owner in Amersham or the surrounding Chilterns area and you want a charger that gives you control over when and how fast you charge, the Zappi Glo is worth considering. Its smart features let you:

• See real-time energy use on your phone
• Set charging schedules to match off-peak electricity rates
• Integrate with solar panels or battery storage for maximum efficiency
• Adjust charging speed based on available power

The Zappi Glo suits homes with modern electrical infrastructure and homeowners who want to optimise their energy use. If you're planning to add renewable energy to your home — whether that's solar panels or battery storage — the Zappi Glo's smart integration makes it a natural fit.

At this Amersham property, the combination of good existing infrastructure, a clear customer brief, and straightforward cable routing meant we delivered a fast, reliable installation. The homeowner was charging their car the same day we finished.
