Hypervolt Home 3 Pro Installed in Chalfont St Giles

We recently installed a Hypervolt Home 3 Pro EV charger at a property in Chalfont St Giles, SL9 9PD. This was a complex installation that required careful planning from the outset. One of our NAPIT-certified electricians carried out a free site survey and quickly identified the main challenge: the charger needed to go on a wooden outbuilding where the car parks, but the incoming electrical supply was at the front of the house by the front door. The distance between them meant we had to design a route that would be both safe and neat. The result is a fully functional, Wi-Fi-enabled charger that the homeowner can now use to charge their electric vehicle at home.

Why did this Chalfont St Giles homeowner need such a complex installation?

Many properties in the Chilterns — especially Victorian and Edwardian homes around Chalfont St Giles — have electrical supplies positioned at the front of the building, often near the main entrance. This creates a real challenge when the garage, driveway, or in this case, a wooden outbuilding where the car parks, is at the rear or side of the property. The homeowner's situation was typical of older homes in the area: the main incoming supply meter cupboard was right at the front, but the best place to charge the car was 25 metres away around the perimeter of the garden.

Without a dedicated solution, the homeowner would have had no way to charge their electric vehicle safely at home. A standard 13A socket is not suitable for EV charging — it's too slow and poses a safety risk during extended charging sessions. The Hypervolt Home 3 Pro offered the right balance of power and smart features, but getting it to the outbuilding required proper planning.

What does a Hypervolt Home 3 Pro installation involve when the charger is far from the supply?

Our installation process started with that free in-person site survey. We assessed the entire route from the incoming supply to the outbuilding and identified what needed to happen:

First, we installed a new dedicated EV consumer unit next to the live incoming meter cupboard at the front of the house. This is essential when you're running a high-power charger — it gives the installation its own circuit protection and means the charger doesn't compete with other household circuits.

Next came the cable run itself. We used EV Ultra 12mm cable to carry power through the house. The route was not straightforward: the cable ran under the floorboards in the living room, then around underneath the kitchen worktops, and out through the conservatory. At that point, we connected the cable into a whisker box — a transition point that allows us to switch from one cable type to another.

From the whisker box, we ran 25 metres of SWA armoured cable around the perimeter of the garden. We cleated this cable alongside the wooden outbuilding to keep it secure and tidy. The cable then entered the outbuilding from the rear, which kept the installation looking neat and professional.

Once inside, we mounted the Hypervolt Home 3 Pro on the wooden building. However, the weight of the charger and the cables meant the back of the wooden structure needed reinforcement. We strengthened it so that once everything was installed, we had a solid, safe connection that would last.

We also installed the Type Two cable holder — the connector that lets the homeowner plug in their vehicle — and ran an additional ethernet cable into the outbuilding. The homeowner was planning to upgrade the outbuilding with a router eventually, and wanted a hardwired connection for commissioning purposes. This flexibility is one of the strengths of the Hypervolt Home 3 Pro: you can use Wi-Fi for everyday operation, or hardwire it with a Cat6 ethernet cable for a rock-solid connection.

How did we ensure the charger would work reliably in the outbuilding?

Once the physical installation was complete, we commissioned the Hypervolt Home 3 Pro and tested the connection. The homeowner had Wi-Fi available at the time, so we connected the charger wirelessly. This means they can now monitor charging sessions, set schedules, and manage their EV charging from their smartphone — all without needing to visit the outbuilding.

The Hypervolt Home 3 Pro is a smart charger. It learns when electricity is cheapest and can automatically charge your vehicle during off-peak hours if you set it up that way. It also integrates with home energy systems, which is useful if you're considering adding solar panels or battery storage to your property in the future.

What makes the Hypervolt Home 3 Pro the right choice for a property like this?

The Hypervolt Home 3 Pro delivers 7kW of charging power, which is the standard for most UK domestic installations. This means your electric vehicle gains roughly 25–30 miles of range per hour of charging — enough for most daily commutes overnight.

But what made it the right choice for this Chalfont St Giles property was its smart features and flexibility. The combination of Wi-Fi and hardwired ethernet options meant we could install it in an outbuilding away from the main house and still give the homeowner full control. The charger is also built to last, with robust weatherproofing suitable for outdoor installations.

If you're thinking about adding renewable energy to your home — such as solar panel installation or battery storage — a smart charger like the Hypervolt makes it easy to integrate everything together. You can charge your car during the day when your solar panels are generating, or store excess energy in a battery and use it to charge overnight.
