Electric vehicle charging starts with where the vehicle is parked, how it will be used and the electrical supply available at the property.
A homeowner charging one vehicle overnight has different requirements from a business operating a fleet or installing multiple chargepoints across a car park.
We provide electric vehicle charger installation across the UK for homes, workplaces, businesses, landlords and commercial properties.

An EV chargepoint connects an electric vehicle to the electrical installation at a property.
Choosing the charger itself is only one part of the project.
An installation also needs to consider:
Vehicle charging requirements
Available electrical supply
Property type
Parking arrangement
Charger location
Cable route
Number of vehicles
Existing electrical installation
Future charging requirements
These factors determine what needs to be installed and whether additional electrical work is required.
Home charging gives an EV driver a dedicated charging point at their property.
For many drivers, the vehicle is parked at home for several hours overnight. This creates an opportunity to recharge while the car is not being used.
The installation needs a suitable location for the charger and an appropriate connection to the property's electrical installation.
Cable routing, parking position and available electrical capacity all influence the work required.
The charger should be positioned around the way the vehicle is actually parked.
A unit installed on an external wall may work well where a driveway runs directly alongside the house.
Detached garages and parking spaces further from the building can require a different cable route.
Useful questions include:
Where is the vehicle normally parked?
Where is its charging port located?
Where is the consumer unit or electrical supply?
How will the charging cable reach the vehicle?
Could another EV need charging in future?
Planning around these questions can produce a more practical installation than selecting the chargepoint position in isolation.
Home and commercial chargepoints are available in different configurations.
A tethered charger has its charging cable permanently connected to the unit.
An untethered charger provides a socket, with a separate charging cable used between the vehicle and chargepoint.
Neither arrangement is universally better.
The choice can depend on convenience, appearance, vehicle compatibility and how the charger will be used.
Connected chargepoints can provide additional control over when a vehicle charges.
Depending on the charger and service being used, functionality can include scheduling, monitoring charging sessions and integrating charging with different electricity tariffs.
For a domestic installation, this can allow charging to be scheduled around the driver's routine.
For businesses, connected systems can provide additional management capabilities where multiple chargers or users are involved.
Workplaces create a different charging pattern from homes.
Vehicles can remain parked for much of the working day, giving businesses an opportunity to provide charging for employees or company vehicles.
A workplace installation can begin with a small number of chargers or form part of a larger parking strategy.
The project should consider:
number of parking spaces → expected EV users → charging demand → available electrical capacity → charger configuration
This helps determine how many active chargepoints the site can support and whether provision should be made for future expansion.

Commercial EV charging can cover anything from several chargers outside an office to a larger installation serving a fleet, residential development or customer car park.
The electrical requirements can increase considerably as charger numbers and charging power increase.
Commercial projects can therefore involve:
Site surveys
Electrical capacity assessment
Charger positioning
Distribution equipment
Cable routes
Groundworks
Protective equipment
Load management
Charger commissioning
Network or software configuration
The final design depends on the site rather than simply multiplying a domestic installation by the number of required chargers.
Businesses install EV charging for different reasons.
Some need to charge company vehicles.
Others want employees to charge while they work.
A hotel might want chargers for guests, while another business may want charging available to customers.
Understanding who will use the chargers is therefore one of the first design decisions.
Employees → workplace charging
Company vehicles → fleet charging
Customers → destination charging
Residents → residential charging
The use case affects the charger configuration and management requirements.
Fleet charging is built around vehicle operations.
The important question is not simply how quickly an individual vehicle can charge.
It is whether the required vehicles can receive enough energy before they are needed again.
A fleet assessment can consider:
Number of vehicles
Daily mileage
Vehicle battery capacity
Arrival times
Departure times
Dwell periods
Simultaneous charging demand
Available site capacity
Charging can then be planned around the operational schedule.
For some fleets, vehicles remain parked overnight.
Others return to a depot at different times throughout the day.
Those patterns can lead to very different charging requirements.
Car parks provide opportunities for charging across workplaces, commercial premises, residential developments and other properties.
Larger car parks introduce additional infrastructure considerations.
The chargers may be located a considerable distance from the existing electrical supply.
Installation can therefore require groundworks, distribution equipment and longer cable routes.
The project also needs to consider how charging bays fit into the existing parking layout.
Landlords can install charging infrastructure at eligible residential properties.
The requirements vary depending on whether the property has an individual parking space or shared parking serving multiple homes.
A landlord project can involve:
Individual chargepoints
Shared parking areas
Multiple charging bays
Electrical infrastructure
User access
Running-cost arrangements
Future charger provision
For larger residential developments, considering future demand at the infrastructure stage can be particularly useful.
Installing an EV charger for a flat can be more involved than installing one beside a house.
The parking space may be remote from the dwelling.
Electrical supplies can be located within communal areas.
Permission may also be required from the freeholder, landlord or property manager.
The installation therefore needs to consider both the electrical route and the legal right to install equipment within the relevant areas.
Where several residents require charging, a coordinated development-wide system may be more appropriate than treating every parking space independently.
Hotels can provide charging while vehicles are parked for extended periods.
Guest charging requirements can differ from fleet charging because arrival times, vehicle types and length of stay vary.
A hotel installation might begin with several charging bays while retaining the ability to expand as demand changes.
Where chargers are intended for guests or other visitors, payment and access arrangements may also form part of the system requirements.
Office car parks can support charging for employees, company vehicles and visitors.
The number of chargers required does not necessarily need to equal the number of EVs that may eventually use the site.
Charging demand depends on vehicle dwell time and how frequently each user needs to charge.
Load management and charging policies can help businesses manage demand across multiple vehicles.
Retail sites and other customer-facing properties have different charging patterns again.
Vehicles may remain parked for considerably less time than they would at a home or workplace.
Charger selection therefore needs to consider typical dwell time alongside available electrical capacity and the purpose of providing charging.
Commercial considerations can also include:
User access
Payment
Bay management
Signage
Charger monitoring
Ongoing operation
These requirements should be considered during the project design rather than after chargers have been installed.
Every charger ultimately places demand on an electrical supply.
The available capacity therefore matters.
A single domestic charger and a bank of commercial chargepoints present very different electrical loads.
Before installation, the existing electrical arrangements need to be considered to establish how the proposed charger or chargers can be supplied.
Where additional capacity or changes to the electrical infrastructure are required, these become part of the project.
Multiple EVs do not necessarily need to draw their maximum charging power simultaneously.
Load-management systems can distribute available capacity between chargers.
For example:
Site capacity available for EV charging
↓
Several vehicles connected
↓
Charging demand managed between vehicles
↓
Available electrical capacity allocated
This can be particularly useful for workplaces, apartment developments and fleet installations.
The appropriate arrangement depends on the charging system and operational requirements.
Discuss a Commercial EV Charging Project
The electrical supply available at a property can influence the charging equipment that can be installed.
Many domestic properties use a single-phase supply.
Commercial and industrial premises may have three-phase electrical supplies capable of supporting different charging arrangements.
This does not mean every property with three-phase power should automatically receive higher-powered chargers.
Vehicle capability, dwell time, site capacity and charging demand should all be considered together.
AC chargepoints are commonly used where vehicles remain parked long enough to charge over a period of time.
Applications can include:
Homes
Offices
Workplaces
Hotels
Residential developments
Long-stay parking
Fleet depots
The vehicle's onboard charging capability also affects the rate at which AC power can be accepted.
Installing a charger with a higher nominal output does not necessarily mean every vehicle will charge at that maximum rate.
DC charging supplies power differently from conventional AC chargepoints and can provide substantially higher charging power where the vehicle and infrastructure support it.
This can be relevant where vehicles need to receive significant energy during shorter stops.
However, higher-powered charging places greater demands on the site's electrical infrastructure.
A rapid-charging project can therefore require considerably more planning around supply capacity, distribution equipment and site layout.
The appropriate charging power should follow the operational requirement.
The distance between the electrical supply and the charging bay can significantly affect an installation.
A charger mounted directly outside a building may require a relatively straightforward cable route.
A charger positioned in the middle of a commercial car park can require underground cabling and associated groundworks.
Site design can therefore involve:
electrical supply → distribution → cable route → charger → parking bay
Planning this route early helps establish the actual infrastructure required.
The number of EVs using a site is likely to change over time.
Installing two chargers today does not necessarily mean the electrical design should ignore the possibility of ten vehicles requiring charging later.
Where appropriate, infrastructure can be considered with future expansion in mind.
This might involve planning:
Distribution capacity
Cable routes
Ducting
Charger locations
Load management
Additional parking bays
Future provision can be particularly valuable where later groundworks would otherwise require reopening completed car parks or landscaped areas.
Some homes, landlords, workplaces and other eligible applicants can receive government support towards EV chargepoint installation.
Eligibility depends on the current scheme, applicant, property and installation.
Grant requirements can also specify eligible equipment and authorised installers.
Because schemes and funding levels can change, eligibility should be checked against the current government guidance when planning the installation.
Eligible organisations can use the Workplace Charging Scheme to contribute towards the cost of EV charging at workplaces.
The scheme operates subject to eligibility requirements and limits on the number of supported sockets.
Businesses considering grant funding should establish eligibility before arranging the installation.
There is no single EV charger that is appropriate for every installation.
Selection should follow the charging requirement.
Consider:
Vehicle
What can it accept?
Parking time
How long is it normally connected?
Electrical supply
What capacity is available?
Users
One driver or many?
Location
Home, workplace, fleet or public-facing site?
Management
Is access control, monitoring or payment required?
Future demand
Will more chargers be required?
Once these are established, suitable charging equipment can be considered.
A straightforward domestic installation and a large commercial charging project have different requirements, but the underlying process is similar.
1. Establish how charging will be used
Home, employee, fleet, resident or customer charging.
2. Review the site
Consider parking, charger positions and cable routes.
3. Assess the electrical installation
Establish the available supply and proposed charging demand.
4. Select the charging equipment
Match the charger to the vehicle, site and management requirements.
5. Plan any additional infrastructure
This can include distribution equipment, cabling and groundworks.
6. Install and commission the system
Complete the electrical installation and configure the chargepoint as required.
