A car park can serve hundreds of vehicles every day, but those vehicles do not all need the same type of EV charging.
Employees may remain for eight hours. Hotel guests can stay overnight. Shoppers may park for an hour, while fleet vehicles can have fixed departure times.
A successful car park charging installation starts by understanding these users before deciding how many chargers to install.
We install car park EV chargers in Canvey Island for commercial properties, workplaces, customer parking and other suitable off-street car parks.

Divide the car park into user groups.
These might include:
employees
customers
visitors
hotel guests
residents
fleet vehicles
general public
Each group creates a different charging pattern.
A staff car park may be occupied all day. A retail car park may experience constant turnover. A hotel has much longer overnight stays.
The charging network should reflect those patterns.
Dwell time is one of the most useful pieces of information when designing car park EV charging.
If a vehicle remains parked for eight hours, there is considerably more time to deliver energy than if it leaves after 45 minutes.
This creates:
energy required ÷ parking window = charging requirement
Higher charging power can become important as parking periods become shorter.
Longer stays create more flexibility.

There is no fixed percentage that suits every existing car park.
Start with current demand.
How many EV drivers already use the site?
How often are existing chargers occupied?
How quickly is demand growing?
How many parking spaces can practically be allocated to charging?
Then consider future demand.
A car park can be designed so that the number of active chargers increases over time rather than installing the anticipated long-term maximum immediately.
A charging bay should have a clear purpose.
If an EV bay is regularly occupied by vehicles that are not charging, the infrastructure cannot be used effectively.
Operators therefore need to consider how charging spaces are identified and managed.
This can involve appropriate:
Signage
Bay markings
Parking restrictions
User information
Charging policies
The exact arrangement depends on whether the car park is private, customer-facing or publicly accessible.
Charger position affects both the electrical installation and the user experience.
Spaces near the electrical supply can reduce distribution distances.
But those spaces may not always be the best operational location.
Consider:
Electrical infrastructure
Vehicle circulation
Pedestrian routes
Accessible parking
Charger visibility
Customer entrances
Staff parking
Future expansion
The cheapest location to electrify is not necessarily the best location for the charging network.
Discuss Your Car Park Charging Layout
Customer-facing car parks need charging that fits the typical visit.
A supermarket, restaurant, hotel and leisure centre all have different dwell times.
For example:
convenience retail → short stay
shopping/leisure → medium stay
hotel → long stay
That difference should influence the charging strategy.
The aim is to provide a useful amount of energy during the time customers would normally spend at the property.
Employee parking provides a long charging window.
Vehicles can remain stationary throughout most of the working day.
This can make managed AC charging appropriate for many workplace car parks.
Instead of requiring every employee vehicle to charge at maximum output simultaneously, available capacity can be distributed across the working day.
The business also needs to decide who can use the charging bays and whether charging is free, subsidised or paid.
Hotels can provide destination charging while guests sleep.
Vehicles may remain parked from the evening until the following morning.
That long dwell period can make overnight AC charging practical for many guests.
Hotels should also decide whether their chargers are:
Guest-only
Available to restaurant visitors
Available to event customers
Staff accessible
Open to the general public
This decision affects access, payment and regulatory requirements.
Retail businesses can use EV charging as part of the customer parking offer.
The appropriate charging system depends heavily on customer behaviour.
If visitors typically remain for several hours, one charging strategy may be appropriate.
If the average visit is brief, the useful charging requirement changes.
Retail operators should also decide whether the chargers are intended solely to support existing customers or operate as a wider public charging facility.
Gyms, cinemas, sports centres and other leisure facilities can have relatively predictable visit lengths.
That creates a natural charging window.
A vehicle can receive energy while its driver is already using the facility.
Charging equipment can therefore be selected around typical dwell time rather than simply installing the fastest charger available.

This is one of the most important decisions for a commercial car park.
A charger can be installed on privately owned land and still be publicly accessible.
For example, chargers available to customers in supermarket or hotel car parks can fall within the rules applying to public chargepoints.
By contrast, chargers restricted exclusively to employees or a company's own fleet are generally not treated as public chargepoints.
Establishing the intended users early helps determine the operational requirements.
Where chargepoints are available to the general public, the operator has responsibilities beyond the electrical installation.
Public charging rules cover areas of the consumer experience such as:
Pricing information
Payment
Reliability requirements for applicable rapid networks
Helpline provision
Chargepoint data
The exact obligations depend on the charging equipment and operation.
A public charging project therefore needs both suitable electrical infrastructure and an appropriate operating model.
Current public chargepoint rules require contactless payment for certain public charging equipment.
New public chargepoints of 8kW and above deployed after the relevant implementation date need contactless payment, either at the individual chargepoint or charging site.
Public chargepoints of 50kW and above are also within the contactless requirement.
This is an important equipment consideration for businesses planning customer or public charging.
A private employee-only installation does not automatically have the same requirements.
Operators of public chargepoints need to consider how charging prices are communicated.
Current regulations require the maximum price of a public charging session to be displayed clearly in pence per kilowatt-hour.
For a business, this means pricing should be part of the charging proposition from the beginning.
Questions include:
Will charging be free?
Will users pay for the electricity?
Will parking and charging be charged separately?
Who operates the chargepoints?
These are commercial decisions as well as technical ones.
Discuss a Public EV Charging Installation
Private charging networks can restrict use to authorised drivers.
This may be appropriate for:
Employee car parks
Fleet areas
Tenant parking
Private business sites
Restricted residential parking
Depending on the charging system, access can be controlled through supported authentication or management functionality.
Establishing the access policy first helps avoid paying for unnecessary public-charging functionality.
Once the charging requirement is understood, the site needs enough electrical capacity to support it.
The potential demand depends on:
number of chargers × charger output × simultaneous use
But theoretical maximum demand does not necessarily equal actual operating demand.
If vehicles remain parked for several hours, charging can potentially be distributed across that period.
That is where load management becomes particularly useful.
Imagine a car park containing 30 chargepoints.
Without management, the electrical design may need to consider substantial simultaneous demand.
With an appropriately designed managed charging system, available capacity can be distributed between connected vehicles.
As vehicles finish charging, power can become available elsewhere.
The charging network can therefore respond to utilisation rather than treating every socket as an independent maximum load.
EV charging is only one part of a commercial property's electrical demand.
The building may also be operating:
Lighting
Heating
Cooling
Machinery
Kitchens
Lifts
Other electrical equipment
Where suitable systems are used, charging demand can be managed alongside the capacity available to the wider site.
This can help reduce conflicts between vehicle charging and other building loads.

The electrical intake may be inside a building while the charging spaces are some distance away.
The installation therefore needs a distribution route.
A larger project can look like:
main electrical supply
↓
EV distribution
↓
external cable route
↓
local distribution
↓
chargepoints
↓
charging bays
The equipment required depends on the distance, charger quantity, charging power and existing electrical infrastructure.
Open car parks can require underground electrical infrastructure.
Groundworks may be needed to establish cable routes between the electrical supply and charging areas.
Depending on the project, work can include:
Excavation
Electrical ducting
Cable routes
Charger foundations
Local distribution
Surface reinstatement
Planning future charger locations during these works can reduce the need to repeatedly disturb the car park as EV demand increases.
Ducting provides a protected route through which electrical cabling can pass.
For larger charging projects, it can also form part of the future expansion strategy.
Suppose a business wants six active chargers today but expects to require 20 later.
The initial project can consider whether infrastructure routes should extend towards the future charging spaces.
The future electrical requirement still needs to be designed appropriately rather than simply installing spare empty ducts without a plan.
Suitable local electrical distribution can be useful where chargers are located away from the main building.
A feeder pillar can form part of that arrangement where appropriate.
The infrastructure might therefore become:
main distribution → feeder pillar → charging equipment
rather than running every individual charger circuit directly from equipment inside the building.
The correct distribution arrangement depends on the design of the charging network.
Car parks beside buildings can sometimes use wall-mounted equipment.
Open parking areas usually require an alternative mounting arrangement.
Free-standing chargers can be positioned within rows of parking using suitable pedestals, plinths or other designed supports.
The decision depends on the physical layout.
Equipment should be positioned so users can connect vehicles without unnecessarily stretching cables across adjacent spaces or pedestrian routes.

Car parks involve constant vehicle movement.
Drivers reverse into spaces.
Delivery vehicles manoeuvre.
Cars can overrun the intended stopping position.
Chargepoint protection may therefore need to form part of the design.
Suitable barriers or other protective arrangements can reduce the risk of vehicle impact where required.
Protection should not create another accessibility problem by making the charger difficult to reach.
Accessibility needs to be considered across the complete charging bay.
The relevant journey is:
park vehicle → exit vehicle → reach charger → handle cable → connect vehicle
The surrounding space can influence every stage.
Charger position, cable weight and reach, kerbs, bollards and pedestrian routes can all affect usability.
For public charging projects, accessible charging guidance should be considered during the layout stage rather than after equipment has already been installed.
Vehicle charging ports are not all in the same position.
They can be located at the front, side or rear of the vehicle.
Cable reach therefore matters when designing charging spaces.
A charger positioned correctly for one model should not unnecessarily restrict other compatible vehicles.
Where chargers serve general customers or the public, the range of vehicles likely to use them should be considered.
Charging infrastructure should not unnecessarily obstruct normal pedestrian movement.
Cables, charger bases, protective equipment and other infrastructure all need to fit around the routes people use through the car park.
This is especially important near:
Building entrances
Accessible spaces
Footways
Crossing points
Retail entrances
Hotel receptions
The charger is only one element of the parking environment.
Clear signage helps users identify charging spaces and understand how they operate.
Depending on the car park, signage may communicate:
Charging-space designation
Parking restrictions
User eligibility
Charging instructions
Payment information
Time restrictions
Public and customer-facing charging should be straightforward to identify without requiring drivers to search around the car park for the equipment.
AC charging can be useful where vehicles remain parked for longer periods.
This can include:
Employee car parks
Hotels
Long-stay parking
Offices
Residential parking
Some leisure facilities
The long dwell time allows energy to be delivered over several hours.
For these applications, installing substantially higher charging power may provide limited additional value if the vehicle will remain parked long after it has received the energy it needs.
Rapid and higher-powered DC charging can become more useful where drivers stay for shorter periods.
This may include:
High-turnover customer sites
Dedicated charging destinations
Transport operations
High-mileage commercial vehicles
Higher charging power can significantly increase the electrical infrastructure required.
The business case, vehicle dwell time and electrical capacity should therefore be considered together.
Not every bay needs identical equipment.
A car park can potentially provide different charging options for different users.
For example:
staff parking → longer-dwell AC charging
customer parking → charging selected around visit duration
fleet area → operational charging
short-stay area → higher-powered charging where justified
This avoids designing the entire site around its most demanding charging use.
Connected charging systems can provide useful information about how the car park is actually being used.
Depending on the selected platform, this can include:
Charging sessions
Energy delivered
Charger occupancy
Equipment availability
User activity
Fault information
This data can inform the next stage of expansion.
If every charging space is consistently occupied, more provision may be justified.
If utilisation remains low, the operator can understand that before committing to another large installation.
Plan Your Car Park Charging Network
Car park charging demand is unlikely to remain static.
The initial installation should therefore consider where additional charging spaces could be introduced.
A useful approach is to distinguish between:
active charging spaces now
and
potential charging spaces later
Electrical distribution, cable routes and physical layout can then be considered against both.
This does not mean installing unused chargepoints years before they are required.
It means avoiding infrastructure decisions that make future expansion unnecessarily difficult.
Larger projects can be divided into phases.
Install the chargers required by current users.
Use actual charging behaviour to understand demand.
Add chargepoints as utilisation and EV numbers increase.
Adjust charging management and infrastructure as the network becomes larger.
This gives the operator evidence on which to base expansion.
A new development provides an opportunity to consider charging infrastructure before the final car park surfaces are completed.
Cable routes, ducting and charging locations can be coordinated with the wider electrical and construction design.
This can be considerably different from retrofitting an established car park where finished surfaces and existing services are already in place.
Applicable building and planning requirements should be considered as part of the development.
Existing car parks can be upgraded with EV charging, but the design needs to work around what is already there.
That includes:
Existing electrical infrastructure
Surfacing
Drainage
Underground services
Parking layout
Pedestrian routes
Existing bay markings
A site survey helps establish the practical route between the electricity supply and proposed charging spaces.
Businesses should be careful with older information about EV car park infrastructure grants.
The previous staff and fleet infrastructure grant and commercial landlord chargepoint grant closed to new applications on 31 March 2026.
The Workplace Charging Scheme remains available for eligible workplace chargepoint installations.
Whether a particular car park project qualifies depends on the current scheme and intended use.
Grant eligibility should therefore be checked before the installation is arranged rather than assumed from the presence of commercial parking.
A car park charging project can be reduced to seven decisions.
Who will charge?
How long do they park?
Where should charging take place?
How much electrical capacity is available?
How will electricity reach the bays?
How will access, payment and charging be managed?
Where will the next chargers go?
Answering those questions creates a much clearer specification than beginning with a charger brand or arbitrary charger quantity.

A site or car park plan is particularly useful for larger installations.
If possible, identify the electrical intake and preferred charging area on the plan.
We install car park EV chargers in Canvey Island for businesses, workplaces, hotels, retail properties and other suitable parking facilities.
Projects can include individual charging spaces and larger managed networks incorporating electrical distribution, load management, groundworks, ducting and infrastructure for future chargepoints.
The appropriate installation depends on more than the number of parking spaces.
It depends on who uses those spaces, how long vehicles remain and how the charging network will operate.
Start with the car park users.
From there, the charging bays, electrical infrastructure and charger specification can be designed around the actual demand.
