A workplace EV charging project should begin with the people and vehicles that will use it. The number of chargepoints matters, but so do parking patterns, dwell times, electrical capacity and the way access will be managed after installation.
Those decisions affect the hardware, cable routes, software and future expansion. If they are left until equipment has already been selected, the result can be a system that is technically installed but awkward to operate.
For facilities managers, estates teams and business owners, this guide explains the questions to resolve before appointing an installer or committing to a design.
Plan the charging requirement
A useful workplace charging design starts with a clear picture of who will use the chargepoints and how long their vehicles will remain parked. This helps the project team choose an arrangement based on real charging needs.
Define what the charging system needs to achieve
Start with the business case for workplace charging.
Some organisations want to support employees who cannot charge at home. Others need dependable charging for company cars, pool vehicles or visiting drivers. A mixed-use car park may need to serve several groups under different access rules.
Write down who the intended users are and what a successful charging session looks like for each group. That brief should cover:
- Staff vehicles and typical working hours.
- Company or pool vehicles and when they need to be ready.
- Visitors, contractors or customers who may require access.
- The number of electric vehicles expected now and over the next few years.
- Any reporting required by finance, fleet or sustainability teams.
This information gives the project team a better basis for design than choosing a number of sockets in isolation.
Use parking behaviour to inform charging speed
The highest available charging power is not automatically the most useful choice for a workplace.
A vehicle parked for most of the working day has a different charging requirement from one that returns briefly between appointments. Fleet vehicles may arrive together at the end of a shift, while staff vehicles may remain connected long after they have received enough energy for the journey home.
Review real parking and travel patterns before selecting equipment. Useful information includes arrival and departure times, average daily mileage, vehicle battery sizes and how often each bay turns over.
The power advertised for a chargepoint is also not a promise that every vehicle will receive that rate throughout a session. The vehicle, the electrical supply and any load-management rules can all affect the power delivered.
An installer can use the operating data to help establish an appropriate mix of chargepoints and explain the assumptions behind the proposal.
Plan electrical capacity and control
The proposed charging demand needs to be assessed against the site’s existing electrical infrastructure. Early capacity checks can identify whether load management, distribution upgrades or discussions with the DNO may be required.
Assess the electrical capacity early
Adding several chargepoints creates a new electrical demand. The existing incoming supply and distribution system need to be considered alongside the building’s normal loads.
A site survey may need to review:
- The incoming supply and agreed capacity.
- Existing maximum demand and patterns of use.
- The condition and capacity of relevant distribution equipment.
- Proposed cable routes and distances to the parking area.
- Other planned loads, such as new machinery, heating or solar equipment.
The survey should identify what is known, what needs measuring and whether discussions with the distribution network operator, or DNO, are required.
The Energy Networks Association explains that multiple high-demand appliances can overload a connection and that a network upgrade may be required where the local network cannot accommodate the additional load. Read the ENA guidance on connecting EV chargepoints.
Allow for this work in the programme. A connection application or supply alteration can affect the project sequence, so it is better addressed before installation dates are fixed.
Decide how electrical demand will be managed
Load management can control how the available power is shared between chargepoints. Instead of assuming every socket will operate at its maximum rating at the same time, the system can adjust charging to remain within an agreed site limit.
That can be useful, but it needs a clear design basis. Ask:
- What limit will the charging system operate within?
- Is the control based on a fixed allowance or the building’s live demand?
- How will available power be divided when several vehicles are connected?
- What happens if communications or the control system fails?
- Can the arrangement accommodate additional chargepoints later?
Chargepoints sold for private workplace use in Great Britain are generally covered by the Electric Vehicles Smart Charge Points Regulations 2021. The regulations set requirements for smart functionality, security and user information, with defined exclusions. Read the government guidance on smart chargepoint regulations.
The installer and equipment supplier should confirm which requirements apply to the proposed system and how the selected products comply.
Design workplace use and management
The charging system must work as part of the wider workplace, including its parking arrangements, pedestrian routes and access policies. Decisions about users, software and day-to-day management should therefore be made alongside the physical design.
Design the parking area for everyday use
The electrical design is only part of the user experience.
Chargepoint locations should work with the dimensions of the parking bays, pedestrian routes and the way vehicles will approach the space. Consider cable reach, the position of charging ports on different vehicles and the risk of cables crossing walking routes.
The design should also address lighting, signage, impact protection where vehicles or equipment could strike the units, and access for maintenance.
Accessibility needs to be considered from the outset. A charger can be difficult to use if controls are poorly positioned, the cable is hard to handle or there is insufficient space beside the vehicle. Where a project uses the Workplace Charging Scheme, current technical requirements say the installation must consider BS 8300. Read the current Workplace Charging Scheme installer guidance.
Ask the project team to review the complete route from arriving at the site to connecting the vehicle, not only the position of the charger on a drawing.
Agree who can use the chargepoints
Access policy affects the equipment and software specification.
Decide whether charging will be available to all staff, allocated users, fleet vehicles or a combination. If demand is likely to exceed the number of bays, set expectations around booking, time limits or moving a vehicle after charging.
The organisation should also decide whether electricity will be provided without charge, recovered through payroll or another process, or accounted for separately for company vehicles. Finance and HR teams may need to review the proposed arrangement.
If customers or the general public will be able to use the chargepoints, do not assume the system remains an exclusively workplace installation. Government guidance states that the Public Charge Point Regulations 2023 apply to chargepoints accessible to the public, while chargepoints restricted to staff or fleet use are outside that legislation. Check the scope of the Public Charge Point Regulations.
Confirm the intended access model before procurement so that any payment, reporting and operational obligations can be assessed properly.
Choose the management platform as carefully as the hardware
Many workplace charging systems use a management platform to authorise users, monitor sessions, apply charging rules and produce reports.
Before choosing a platform, identify who will administer it and what information they need. Ask the supplier to demonstrate the routine tasks that matter to your team, such as adding a driver, changing access permissions, reviewing energy use or investigating a failed session.
The commercial arrangement deserves the same attention. Establish what services are included, which functions depend on an ongoing subscription and how data can be accessed if the supplier changes.
Also ask how the chargepoints operate if their communications connection is temporarily unavailable. The answer should be clear enough for the facilities team to understand what drivers will experience and what action may be required.
Deliver and manage the installation
A workplace EV charging installation may involve electrical works, groundworks, data connections and changes to parking access. Coordinating these elements properly helps the project progress while limiting disruption to normal site operations.
Plan the installation around site operations
Workplace EV charging can involve more than mounting chargepoints. New distribution equipment, containment, trenching, ducting, protective barriers and data connections may all form part of the project.
Review the work alongside normal site activity. Parking bays may need to close in phases. Deliveries, pedestrian routes and emergency access must remain coordinated, while any electrical shutdown needs to be agreed with the people responsible for the affected services.
The programme should identify:
- Surveys and design information required before work starts.
- Landlord, planning or site permissions where applicable.
- Any DNO or metering activity.
- Civil and electrical work and the order in which they will occur.
- Testing, commissioning and user setup.
If the installation is part of a wider refurbishment or car park project, assign responsibility for the interfaces. Confirm who provides bases, duct routes, line marking, signage and final surfacing rather than allowing each package to assume another contractor will deal with them.
Prepare for expansion without overbuilding the first phase
The number of electric vehicles using the site is likely to change. Future planning does not necessarily mean installing every chargepoint immediately.
It may be sensible to consider spare capacity in distribution equipment, routes for additional cabling, empty ducts beneath new surfaces or a management platform that can support more sockets. These measures should be based on a realistic expansion plan and a technical assessment.
Set out what the next phase would require. A design described as future-ready is only useful if the project records explain which parts can be extended and which constraints would still need to be addressed.
Keep the site drawings, circuit information, load-management settings and equipment records up to date. They will shape the next phase and make future decisions easier.
Agree handover and ongoing support
Completion should include the information needed to operate and maintain the charging system.
Depending on the project, the handover may include electrical certification, commissioning records, equipment details, warranties, drawings, user instructions and administrator access to the management platform. Confirm the exact requirements before installation begins.
Nominate someone to own the system after handover. Drivers need a clear route for reporting faults, and the facilities team needs to know who monitors availability, arranges maintenance and manages user access.
Agree how remote support and site attendance work, including what information the support provider will require when a fault is reported. A simple internal process can prevent a minor issue from leaving a chargepoint unavailable for longer than necessary.
Prepare to move the project forward
Before requesting a detailed proposal, gather the information an installer will need to understand the site and the intended use of the system. This is also the right stage to check current grant criteria and identify any permissions or approvals.
Check current grant requirements before work begins
The Workplace Charging Scheme may support eligible businesses, charities and public sector organisations installing chargepoints for staff or fleet use.
As of September 2026, the scheme is scheduled to run until 31 March 2027. Eligibility, approved equipment, installer authorisation and the order of application and installation all matter. Government guidance states that the applicant applies first and an authorised installer claims on its behalf after completing eligible work. Check the latest Workplace Charging Scheme guidance.
Grant rules can change. Check the current criteria before ordering equipment or starting work, and do not base the technical design solely on the available funding.
What to prepare for the first site discussion
Gather a small amount of practical information before speaking to an EV chargepoint installer.
Provide a site plan or marked-up parking layout, current and expected vehicle numbers, typical parking durations and the proposed access policy. Include available electrical records, operating hours, known future loads and any dates linked to fleet changes or wider construction work.
Identify the people who can answer questions about the electrical installation, parking management, fleet use and IT requirements. Record uncertainties openly so the survey can address them.
This gives the installer a useful starting point for planning the site assessment and defining the information required for a proposal.
