EV Charger Installation for New Homes What You Need to Know
Moving into a new home and setting up EV charging from scratch is one of the best opportunities you will get because you are starting with a blank canvas. No legacy wiring to work around. No existing installation to unpick. Just the chance to design a home charging setup that is right for your car, your parking arrangement, and your daily routine from day one.
Done well, home EV charging is one of the most convenient things about owning an electric car. You plug in when you get home, wake up to a full battery, and never think about it. Done poorly wrong charger, wrong position, wrong cable provision it becomes a daily frustration.
This guide covers everything you need to know about EV charger installation for new homes in the UK charger selection, installation requirements, groundworks, posts, cables, and the decisions that are worth getting right at the planning stage.
Why New Homes Are the Best Opportunity for EV Charging Setup
Installing EV charging in an existing home often involves working around constraints limited consumer unit capacity, existing cable runs in inconvenient locations, garden paths and driveways that need breaking up to route cables, and aesthetic considerations imposed by structures that were not designed with EV charging in mind.
New homes eliminate most of these constraints:
- Cable runs can be planned and installed during construction under floors, through walls, in conduit buried before landscaping is complete
- Consumer unit capacity can be planned with EV charging load in mind from the start
- The position of the charge point can be designed around the parking layout rather than retrofitted to an existing structure
- Groundworks for EV posts can be completed before the driveway is laid rather than breaking up a finished surface
If you are moving into a new home or if you are involved in specifying a new build the time to plan the EV charging installation is before the ground is covered and the walls are finished, not after.
Choosing the Right Home EV Charger
The EV charger is the central element of any home charging installation. The right choice depends on your car, your electricity supply, and how you use the vehicle.
Smart vs non-smart chargers
Most modern home EV chargers are smart connected to your home Wi-Fi and controllable via an app. Smart chargers allow you to:
- Schedule charging for off-peak electricity tariffs saving significant money if you are on an EV-specific time-of-use tariff
- Monitor energy usage and charging history
- Set charge limits to preserve battery health
- Integrate with solar generation where applicable
For most new home installations in 2026, a smart charger is the appropriate choice. The cost premium over a basic charger is modest, and the long-term savings from smart scheduling are meaningful.
7.4kW vs 22kW home chargers
The majority of UK home EV chargers are 7.4kW single-phase 32A units that provide a full charge overnight for most electric vehicles. For a car with a 60-75kWh battery, a 7.4kW charger delivers a full charge in eight to ten hours easily completed overnight.
22kW home chargers require a three-phase electricity supply not standard in UK domestic properties. While available, three-phase supply in a new residential property is unusual and typically requires a specific upgrade from the Distribution Network Operator. For most new homes, 7.4kW is the correct specification.
Tethered vs untethered
Tethered chargers have a permanently attached cable convenient for daily home use because the cable is always there and ready. Untethered chargers have a socket rather than a fixed cable requiring you to plug in your own EV charging cable each time, but offering flexibility if you change vehicles or want to share the charger between different cable types.
For a dedicated home installation where the same car charges daily, tethered is usually more convenient. For households with multiple EVs using different connector types, untethered with the appropriate cables provides more flexibility.
Understanding Your Electricity Supply Capacity
Before any home EV charger installation, the electrical supply capacity of the property needs to be assessed. A 7.4kW charger draws 32A continuously during charging which is a significant additional load on the household electrical system.
Most UK new homes have a 100A single-phase supply which is typically sufficient to support a 7.4kW charger alongside normal household load. However, consumer unit capacity and the installed fuse rating both need to be verified.
Key supply considerations:
- Main fuse rating the main fuse at the meter should be rated at 100A minimum for a comfortable 7.4kW installation
- Consumer unit capacity a spare double-pole MCB slot of appropriate rating is needed for the charger circuit
- Load management smart chargers with dynamic load management can modulate charging speed in response to total household load preventing the charger from overloading the supply during periods of high household demand
For new homes, the electrical installer specifying the consumer unit should account for EV charging load as part of the overall electrical design. This is significantly simpler at new build stage than upgrading capacity in an existing property.
Wall Mounted vs Post Mounted Chargers: Which Is Right for Your New Home?
The physical mounting of the charger depends on the parking arrangement at the property.
Wall mounted chargers
If the parking is directly adjacent to the house a garage, a car port, or a driveway where the car parks close to the building a wall-mounted charger is typically the most straightforward and cost-effective installation.
The charger is fixed to the external wall of the property, with the supply cable running internally through the wall to the consumer unit. No groundworks are required. Installation is typically the most straightforward configuration.
Post mounted chargers
If the parking is not adjacent to the building a detached garage, a driveway where the car parks away from the house, or a property where running a surface cable from the building to the charge point would be impractical an EV charger post provides a freestanding mounting solution.
EV posts are installed with a concrete foundation and supply cable routed underground from the consumer unit. This is where the new home opportunity is most valuable groundworks for an underground cable run and post foundation are straightforward to complete before the driveway is laid, and significantly more disruptive to carry out after the surface is finished.
Post mounted installations typically involve:
- Groundworks trenching for the underground supply cable from the building to the post location
- Conduit installation in the trench protecting the supply cable
- Cable installation through the conduit
- Post foundation concrete foundation block for the EV post
- Post installation and connection
- Charger mounting on the post and final connection
For new home installations where a post is needed, completing the groundworks at the construction stage before landscaping and driveway surfaces are laid is by far the most efficient approach.
EV Charger Groundworks: Planning at New Build Stage
Groundworks for EV charging at new build stage are modest in scope but disproportionately valuable because they are easy before the ground is covered and expensive after.
The key groundworks elements are:
Cable trench
A trench from the point where the supply cable exits the building to the charge point location. Depth requirements depend on the cable protection used armoured cable buried to appropriate depth, or standard cable in protective conduit. At new build stage, this trench can be planned and dug as part of the wider site groundworks.
Conduit installation
Protective conduit laid in the trench before backfilling provides a duct through which the supply cable can be pulled and through which future cable upgrades can be made without re-excavating. Installing conduit at the groundworks stage costs very little and provides significant long-term flexibility.
Foundation for EV post
If a post-mounted charger is the intended solution, the concrete foundation block for the post is best poured before the driveway surface is laid. A well-specified foundation ensures the post is stable and level, and avoids the need to cut into a finished driveway surface later.
Cable pull-through
Once conduit and trench are in place, pulling the supply cable through is a straightforward final step before connection at both the consumer unit and the charge point ends.

EV Charging for New Homes: What the Regulations Say
Since 2022, UK building regulations have required new homes with associated parking to be provided with EV charging infrastructure as part of the construction. This means:
- New residential properties with dedicated parking must include a charge point or cable route infrastructure as built
- The requirement applies to new build dwellings and to buildings undergoing major renovation where the number of parking spaces exceeds a defined threshold
For new homeowners taking possession of a property built under these regulations, a charge point or cable route infrastructure may already be in place. Where infrastructure is in place but a charger has not been installed, the cable route simplifies the installation of the actual charger unit significantly.
For new builds not yet completed, ensuring the developer has complied with the regulation and understanding what has been installed is worth confirming before handover.
