Ohme Home Pro EV Charging Installation


Client: Domestic Customer
Project length: 1/2 Day
Completion date: February 2022
HF divisions involved: Electrical, Green Energy

Brief project description: We were contracted to install a brand new Ohme Home Pro EV charger for a customer in Glasgow. What makes the Ohme Home Pro EV charger so special is that it has full 4G capabilities. This connects the system to its own back office and allows the customer to select which energy tariff they are using when charging their electric vehicle.

The 4G connected charger then inputs the cost per unit of electricity at the time and gives the customer an accurate cost per charge (depending on the battery level of the vehicle at the time of charging, and the target charge level they are trying to achieve). This allows the customer to see when is the best time of the day to charge their vehicle, creating real cost potential to the customer over the course of the year (for example if their tariff was on a lower rate at night time to encourage overnight charging).

Project Challenges: During the initial site survey for the EV Charging Installation, our Engineers spotted that the customers supply to their home was looped. This method of supplying semi-detached and terraced properties in Glasgow was once a popular choice and means that one cable has been taken from the main supply cable in the street to one house. Then another cable ‘loops’ from this supply to the house(s) next door.

Scottish Power will not allow the connection of an EV charger with this type of supply. As a result, the customer was needing to have their home un-looped from the next-door neighbour’s electrical supply. Scottish Power were called out to install a brand new supply cable to the property – completely free of charge to the customer.

Because our engineers picked this up during the initial home survey and highlighted the problem to SP Energy Networks at the point of application, it took all the hassle away from the customer. It is this level of detail and service that we are so proud of when it comes to electrical installations such as EV Charging Point fitting.

When the property was ‘un-looped’, SP Energy Networks informed us that the works were complete and we were able to carry out our full installation of the new Ohme Home Pro EV Charger.

What the customer said

“Highly recommend HF for EV Charger installation. I got several quotes but HF were the only supplier who actually did an in-person site visit. Just as well too as they spotted I was on a looped supply. They then submitted the request to Scottish Power on my behalf to have a direct supply installed to my home and helped me navigate my way through that confusing process. Once that was done the installation of the charger was spot on – an excellent piece of work.”

As more and more car manufacturers release new Electric Vehicles with better range and more efficient, faster charging options, there is a growing wave of support from customers looking to make the switch from petrol and diesel powered vehicles. And with more and more of these car owners making the switch to electric vehicles, there is a strong demand for at home charging systems to be fitted.

The different types of EV Charger

EV charging points are not like petrol stations with universal pumps. There are multiple branded manufacturer options available and various styles of EV charging station outlets to choose from. Wall mounted 7kW EV chargers are the most common and are compatible with all current electric vehicles on sale (with exception of some hybrid models) and an average charge time for an electric vehicle will take between 6 to 7 hours (though this is getting better all the time). There are faster, more powerful charging systems and even something called ‘Rapid Chargers’ available. Our qualified EV Charger Installation team can advise you on the best fit for your EV Charging needs.

With senior-level hands-on management from initial planning to final handover, and with the opportunity to tap into a wide range of varied services and associated consultants with a skills base and command of technologies which are second to none. Working with HF Group is more than just another service contractor.
