For businesses planning new or expanded charging
EV Site Surveys & Capacity Reviews in Scotland
Find out what your premises can support before committing to chargers. WB Electrical reviews the electrical supply, parking layout and charging requirement, then sets out practical options and the further information needed to move forward.
From our Larkhall base, we review commercial sites across Lanarkshire, Glasgow, Edinburgh and the Central Belt. Wider Scottish and multi-site requirements are considered by agreement.
Understand the site. Plan the next step.
An informed starting point for the investment
Know what is practical before you commit
A survey is useful when the charger requirement is clearer than the installation route. It helps turn an idea, parking plan or expansion request into a brief that can be designed and priced.
Your first chargepoints
Establish sensible bay locations, charging rates and supporting electrical work before selecting equipment or committing to a supplier.
More vehicles or users
Review existing chargers and infrastructure against the next phase, including changing staff demand, fleet shifts or customer access.
Uncertain supply capacity
Understand what needs to be checked when the available power is unclear, records are incomplete or other electrical loads are changing.
Operational needs can be developed through our workplace charging and fleet and logistics charging routes.
Agree the questions and depth of review
What an EV site survey can cover
The scope depends on the premises, available records and the decision you need to make. We agree the review and any separate investigation before work starts.
Supply and actual demand
Existing supply information, distribution, earthing arrangements and available demand records. Consider loading across phases, operating peaks and planned additions such as new plant or heating.
Parking and installation routes
Proposed bays, cable routes, containment, groundworks, distances and reinstatement. Consider pedestrian access, accessibility, vehicle movements, impact protection and maintenance access.
Charging and site interfaces
Vehicle types, time parked, energy needs, user access and communications. Identify landlord, network, planning or building-standards questions and who will resolve them.
A spare way in a distribution board is not proof of spare electrical capacity. Equipment ratings, existing demand, the agreed supply and the proposed charging load need to be considered together.
Fit the review to the working premises
Plan the review around your site
A quiet period can give an incomplete picture of demand. Tell us about busy shifts, seasonal plant and proposed new equipment so the review reflects how your premises operate.
01
Define the requirement
Share the proposed users, charging windows, site plans and records. We establish whether an initial document review, a site visit or a more detailed assessment is appropriate.
02
Review the premises
Arrange access to relevant electrical areas and parking with a site contact. Any checks needing isolation or access beyond a walkaround are agreed in advance.
03
Resolve the information gaps
Identify whether representative load monitoring, further electrical investigation, specialist design or distribution network operator (DNO) input is needed. Record what remains unconfirmed.
Not sure what information is available? Tell us about the site and we can agree a starting point.
A useful basis for the next decision
Clear findings and practical next steps
A record of the review
- The agreed requirement and the areas reviewed.
- Relevant site information and capacity considerations.
- Possible charger locations and infrastructure requirements.
- Assumptions, limitations and information still needed.
Agree the format and level of detail at the outset, including any layout notes or supporting photographs.
Options to take forward
Depending on the findings, options may include an installation using the existing supply, managed charging, a phased rollout, distribution changes or a network capacity application.
The findings distinguish what has been established from what remains subject to monitoring, design or third-party confirmation. A feasibility review does not reserve network capacity or replace a connection offer.
If funding is part of your plan, the survey can help establish technical inputs. Applicant, site and scheme conditions still need checking before installation; see our EV grant and funding guidance.
Site advice informed by delivered work
Practical EV experience behind the review
From site review to workplace charging
WB’s Procladd project in Hamilton brought ten Easee chargepoints into use in 2025. The published project records the initial review of the charging requirement, existing supply, cable routes and access at a working business premises.
That review led into the associated electrical installation, testing and controlled user setup. It is a relevant example of connecting site questions with an installation that can be delivered and managed.
Supplier assurance
Review WB’s published SELECT membership and wider contractor credentials, or ask the office for evidence relevant to your supplier assessment.
Useful answers before arranging the visit
EV site survey questions
Can you tell us how many chargers the site can support?
We review the requirement against the available evidence. The answer depends on site demand, electrical limits, vehicle charging needs and the time available. Where records are insufficient, further monitoring or network confirmation may be needed before a firm design can be agreed.
Can you start with drawings or photographs?
Yes. Existing plans and safely accessible photographs can help define the next step. They cannot verify concealed routes, equipment condition or actual loading by themselves. Do not remove electrical covers or enter restricted areas to collect information for an enquiry.
Is an EV site survey the same as an EICR?
No. This review focuses on the feasibility and requirements of EV charging. An EICR assesses the condition of the electrical installation within its agreed inspection and testing scope. Any condition inspection or additional testing needed for the project should be agreed separately.
Are load monitoring and DNO applications included?
Only where they are part of the agreed scope. We identify whether they are needed and clarify responsibility, costs and the next action. A survey visit alone is not a detailed design, a network approval or authorisation to install equipment.
How long does an EV site survey take?
The visit and findings timescale depends on the site size, access, records and depth of review. Additional monitoring, return visits or third-party responses can extend the process. Tell us about any procurement or installation deadline so we can agree a realistic programme.
Move forward with the appropriate service
Support after the site review
Ready to install?
Take the agreed requirement into electrical design, installation, commissioning and handover.
Need infrastructure changes?
Plan distribution, routes and capacity changes for additional bays or an existing system.
Need to share available power?
Develop the control arrangement around the agreed supply limit and vehicle charging priorities.

Start with the information you have
Discuss an EV site survey
Tell us what you want to establish and where the charging will be located. You can enquire before choosing the charger model or knowing every electrical detail.
Useful information for your enquiry
- Organisation, site address and property or parking ownership.
- Who will charge, vehicle types and typical parking times.
- Approximate charger numbers now and possible future phases.
- Available plans, electrical records and electricity demand data.
- Existing chargers, planned plant changes, access and target dates.
Mention any documents or photographs you hold. The office will confirm which are useful and how to share them.
What affects the survey cost?
Site size, number of supplies or boards, record quality, access and the required findings all affect the work involved. Load monitoring, specialist investigation, additional visits and network applications may need a separate allowance.
Agree the scope, fee and output before proceeding. Any installation quotation or third-party charges should be identified separately.
