How long does commercial EV charger installation take?

Plan the whole project, not just the days spent fitting chargers. Government guidance describes connection quotations taking 5–65 working days depending on size, followed by a separate delivery programme [S1]. Existing capacity can simplify the job; network works, permissions and commissioning can extend it. Obtain dated milestones and their dependencies before announcing an opening. Checked October 2026.

How long does the whole installation project take?

Separate the programme into survey, design, permissions, connection, construction and commissioning. The time spent mounting chargers is only part of that sequence. Government guidance says smaller network connections can take weeks, while very large connections can take months or sometimes years. Those are broad descriptions, not a delivery commitment for your site. [S1]

Ask for a schedule tied to your scope. A workplace using spare capacity should not inherit the programme for a new rapid-charging hub. Equally, a short electrical installation should not be presented as the full lead time when land agreements and network work remain unresolved. Review grid queue reform and timescales when checking the proposed connection programme.

Your useful question is: what must happen before drivers can complete a session? Make that the definition of opening. Include staff access, bay availability and the charging service, rather than recording only the date the equipment arrived.

How long do the survey and grid application stages take?

A distribution network operator (DNO) manages your local electricity network. Government guidance recommends early contact for multiple workplace or depot chargers and explains what the connection application should describe. The designer needs a credible capacity request before the network can assess it. [S1]

Kilowatts (kW) measure power and kilowatt-hours (kWh) measure energy. Record the energy your vehicles need and when they leave, alongside existing site load. This helps the designer avoid requesting capacity solely from the sum of equipment labels. [S5]

The government guide describes connection quotations taking 5–65 working days depending on connection size. Treat this as a published quotation-stage range, not a promise about construction. Ask your DNO which service category applies and when it considers the application complete. [S1]

Prepare the information early:

• Supply and meter details, plus any existing connection agreement.
• A drawing showing the bays and intended cable route.
• Vehicle charging needs and departure times.
• Existing electrical drawings or access for the survey.
• Ownership details and permission to work on the proposed route.

Read what a site survey checks before booking the visit.

Which stages can hold up the opening date?

Ask the installer to identify the task that controls each milestone. A charger in stock does not resolve an unavailable electrical supply. Government guidance explains that connection delivery depends on size and complexity, and that network works can involve permissions and other infrastructure. [S1]

Use the table as a project checklist, not an official sequence for every site. Agree the dependencies with the parties responsible for your actual installation. Use the commercial installation walkthrough to prepare questions for each stage.

Where an upgrade involves meter work, UK Power Networks explains that supplier coordination is separate from its network tasks. Confirm both appointments and who books them. A cable being ready does not mean the meter and supply arrangements are ready too. [S2]

Take land rights, lease changes and consent questions to your solicitor. Allocate responsibility for planning checks explicitly and use the relevant local authority for the site. This is project information, not legal advice.

Can you shorten the programme by changing the design?

Ask for an option that uses existing capacity and another that meets your full preferred scope. Government guidance identifies reviewing load, charging more slowly where suitable and considering flexible connections as options. None removes the need to check vehicle departure requirements. [S1]

For an illustration, assume a vehicle needs 28 kWh and can remain connected for 4 hours. Its arithmetic average requirement is 28 ÷ 4 = 7 kW before losses. If those assumptions match your operation, ask whether a lower-power design changes the connection work. It is a question for design assessment, not evidence that the supply is adequate.

Read dwell time and charger speed and load management versus a grid upgrade. Request any staged installation to include the eventual cable routes and access arrangements, so later work is visible in the decision.

How do grants and funding affect the sequence?

The Workplace Charging Scheme currently offers up to £500 per eligible socket for qualifying completed installations, with the scheme extended until 31 March 2027. Its voucher and claim conditions belong in the programme. Do not use a grant deadline as evidence that the network can deliver by then. [S3]

With fully funded charging, ask which party controls the network application and what happens if approvals change the project. With part funded charging, identify the point at which your contribution becomes payable. With self funded charging, align equipment ordering with the accepted design and contract milestones.

These are contract questions, not prescribed payment terms. Review exit conditions and responsibility for delays with your solicitor. Compare fully funded charging and commercial charger costs before committing.

When is the installation ready for customers?

Define completion before the work begins. Ask for a demonstrated session, operating instructions and the agreed test and handover records. Network Rail’s infrastructure guide covers commissioning and operation, which are distinct from simply putting equipment in the ground. [S5]

For public access, check the applicable pricing, payment and support obligations. Government public charging guidance explains the requirements and their scope. Test the intended customer route, including the tariff display and getting help, before announcing that the bays are open. [S4] Include public map listing checks in your opening plan.

What should you do next?

Bring your target opening date, site drawing and supply information. Ask for a programme showing unresolved dependencies, then get matched with an installer that covers your area.
