Planning permission for a commercial EV charging hub

A commercial electric vehicle charging hub is a full planning application. The permitted development rights in Part 2 of the General Permitted Development Order cover chargepoints installed within an existing off-street parking area, subject to size and siting limits, and they were written for adding equipment to parking that already exists. A purpose-built hub with a canopy, a dedicated substation, welfare facilities and its own access is a development in its own right, and the application stands or falls on grid capacity, vehicle circulation and noise.

The grid connection is usually the long pole. Planning takes a few months. A distribution network operator connection offer can take considerably longer, and the substation it requires is a planning matter in its own right.

Where permitted development covers charging equipment

Part 2 allows a wall-mounted electrical outlet for charging vehicles and an upstand with a charging outlet, in each case within an area lawfully used for off-street parking, with limits on height and size and restrictions near highways and on land with heritage or landscape designations. The rights have been amended, most recently to widen what can be installed without an application.

What they do not cover is the thing a hub operator wants to build. Read the current text of Part 2 on legislation.gov.uk before assuming a scheme fits, and check three points specifically: whether the parking area is already lawfully used for parking, whether the equipment exceeds the stated size limits, and whether the site sits on land where the rights are restricted or removed.

Where the position is arguable, a lawful development certificate under section 192 of the Town and Country Planning Act 1990 is the only formal way to confirm that the installation is permitted development, and for a rollout across a portfolio it is worth doing once on a representative site.

When a hub becomes a full application

Four triggers push a scheme into a full application, and most hubs hit several at once.

The first is a change of use. Converting part of a retail car park to a standalone charging facility serving passing traffic, rather than customers of the store, changes what the land is used for. Whether that is material turns on the planning unit and on scale, so a handful of bays for customers is different from twelve bays with their own entrance and signage. A dedicated hub is usually treated as sui generis.

The second is operational development beyond the Part 2 limits: canopies, substations, payment terminals, welfare buildings, lighting columns and reconfigured hardstanding.

The third is highway works. A new or altered access onto the public highway needs the highway authority's agreement, usually under section 278 of the Highways Act 1980, and on a trunk road National Highways becomes a consultee.

The fourth is screening. An urban development project above the relevant area threshold in Schedule 2 to the Environmental Impact Assessment Regulations 2017 needs a screening opinion, and a hub on a larger site adjoining sensitive receptors may need one even where a formal assessment is not ultimately required. Where an Environmental Statement is needed, the regulations require it to be prepared by competent experts, and an AI-assisted draft is a starting point for those experts rather than a substitute.

Grid connection and substation siting

Start the connection application before the planning application, not alongside it.

A hub running multiple rapid or ultra-rapid chargers draws a load that most existing supplies cannot carry, so the distribution network operator will usually require a new package substation, cable routes and sometimes reinforcement works off site. That has three planning consequences. The substation needs a location, which is rarely the location the layout designer would choose. The cable route may cross third party land, requiring easements. And the reinforcement works may have their own consents and their own programme.

Site the substation where its noise and appearance do least harm, and show it on the submitted plans with dimensions and materials rather than as a dashed rectangle marked "substation, details to follow". Officers dislike that rectangle, and it invites a condition that delays discharge later.

Canopies, lighting and signage

The canopy is what makes a hub read as a petrol filling station to a case officer, and it is the element most often reduced during determination.

Height, span and fascia depth are the sensitive dimensions. A canopy designed for articulated vehicles dominates a site that otherwise sits comfortably in its setting. Where the hub is in a National Landscape, a conservation area setting or open countryside, expect the canopy to be the main design argument, and prepare elevations showing it against the surrounding built form rather than in isolation.

Lighting is assessed against obtrusive light guidance, with the Institution of Lighting Professionals guidance note the usual reference. Provide a lighting layout with isolux contours, luminaire specifications including upward light ratio, mounting heights, and a curfew regime for a site near homes. Canopy lighting recessed into the soffit performs far better than surface-mounted floodlights.

Advertisement consent is separate from planning permission and is granted under the advertisement control regulations. Illuminated totems, price displays and fascia signs each need consideration, and consent for them does not come automatically with the planning permission.

Queuing, circulation and highway capacity

Charging takes longer than refuelling, and that single fact drives the transport case.

A rapid charging bay is occupied for a period measured in tens of minutes rather than minutes, so the queuing behaviour resembles a car park more than a forecourt. The transport evidence should set out expected dwell times by charger rating, the resulting bay turnover, the queue length the site can hold internally, and what happens when the queue exceeds it. A queue that backs onto the highway is the reason highway authorities refuse these schemes.

Swept path analysis for the largest expected vehicle, including any delivery or maintenance vehicle, belongs in the submission, as does a drawing showing circulation, one-way arrangements and the relationship between charging bays and any retail or welfare building. Where trip generation is uncertain, say so and offer a monitoring condition rather than presenting a modelled figure with false confidence.

The Design and Access Statement should carry the circulation logic as a narrative, because the reasoning behind the layout is rarely obvious from the plan alone.

Noise from chargers and cooling plant

High-power chargers have cooling fans, and grouped units running at night beside housing generate complaints that outlast the planning permission.

The assessment follows BS 4142 for industrial and commercial sound, comparing the rating level of the specific sound against the background sound level at the nearest noise-sensitive receptor, with the representative background measured over an appropriate period including the quietest hours the site will operate. Transformer hum from the substation is a separate source and is often the tonal one that attracts complaints.

Mitigation options are limited once the layout is fixed, which is the argument for doing the assessment early. Orientation of the units, acoustic barriers, enclosure of the transformer, distance and a restriction on which units operate overnight all work, and all of them constrain the layout. A noise assessment is a report type where authorities expect a suitably qualified author, and professional review is strongly advised before submission.

Accessibility and assembling the application

Accessible charging is now a design expectation rather than an optional extra. The relevant guidance is the publicly available specification on accessible charging, PAS 1899, which covers bay dimensions, transfer space, kerb heights, the height and force of charging connectors, cable management and lighting levels. Provide a proportion of accessible bays, show the dimensions on the layout, and address the specification in the submission.

The core bundle for a commercial hub looks like this.

1. Application forms, ownership certificates, location and block plans.
2. Site layout with bays, circulation, swept paths, substation and canopy dimensions.
3. Elevations and sections including the canopy and any building.
4. A Planning Statement covering the principle of development, the policy case on decarbonising transport and the sequential position where relevant.
5. A Design and Access Statement.
6. A transport statement or assessment with dwell times, queuing and access design.
7. A noise assessment to BS 4142.
8. A lighting assessment with isolux contours.
9. Drainage details, since large areas of hardstanding change run-off.
10. Landscape and boundary treatment drawings.

Screening opinions, ecology surveys, contamination assessment on a previously developed site and a construction management plan follow from the site rather than from the use.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
