Do You Need Planning Permission for EV Chargers in a Car Park?

Short answer: most EV chargepoints in a commercial car park go in under permitted development (PD) and never touch a planning application. But “most” is not “all”, and the exceptions — listed buildings, conservation areas, land near homes, large DC substations and anything that changes the use of the site — are exactly the ones that catch operators out and add months to a programme. This guide sets out what PD actually covers in 2026, where the limits bite, and when you genuinely need to apply.

Nothing here is legal advice. Planning is site-specific and your local planning authority (LPA) has the final say. Treat this as a working map, not a permission.

Permitted development: what you can install without applying

Since the rules were widened on 29 May 2025, the permitted-development allowances for electric-vehicle charging equipment in England are generous for off-street commercial car parks. In broad terms:

• Free-standing upstands (pedestals): permitted up to 2.7m in height on off-street parking. That covers the vast majority of AC bollards and most DC rapid units.
• The 1.6m rule near dwellings: where the upstand is within 2 metres of a highway, or sited close to a dwelling, the height limit drops to 1.6m. This is the single most common trip-hazard in mixed retail/residential and hotel car parks — a unit that is fine on the far side of the tarmac is not fine against the residential boundary.
• Wall-mounted outlets: permitted where the casing is under 0.2 cubic metres. Note this is a volume limit, not a height limit — a bulky wall box can breach it even when it looks small. Most domestic-style and light-commercial 7kW–22kW wall units sit comfortably under the cap.
• Equipment cabinets: you’re allowed one associated equipment cabinet (housing switchgear, metering, comms) up to 29 cubic metres under PD. That is a large allowance and covers most AC estates; it’s the DC rapid banks that tend to exceed it.

PD also carries standing conditions: equipment must be removed as soon as reasonably practicable when no longer needed, and it must be sited to minimise its effect on the external appearance of the building and on the amenity of the area. Those are qualitative tests an LPA can lean on, so siting judgement matters even inside PD.

Where permitted development stops

PD is a default, not a guarantee. It is withdrawn or restricted in several situations that are common on commercial sites:

Situation	PD status	What it usually means
Standard off-street car park, upstand ≤2.7m, away from homes	✅ Covered by PD	Proceed; keep siting evidence on file
Upstand within 2m of highway or near a dwelling, >1.6m	❌ Exceeds PD	Reduce height or apply for planning
Wall unit casing ≥0.2 m³	❌ Exceeds PD	Reposition, downsize, or apply
More than one equipment cabinet, or one over 29 m³	❌ Exceeds PD	Full application for the cabinet(s)
Listed building / within its curtilage	❌ PD removed	Planning and likely listed-building consent
Conservation area, National Park, AONB, World Heritage Site	⚠️ PD restricted	Often needs prior approval or full application
Site with an Article 4 Direction	⚠️ PD may be removed	Check the direction; assume application needed
Change of use (e.g. car park → public charging hub as primary use)	❌ Not a PD question	Separate change-of-use assessment

Two of these deserve emphasis for car-park operators. First, DC rapid and ultra-rapid banks: a 150kW+ hub often needs a customer HV substation, and the associated cabinet/enclosure frequently pushes past the 29 m³ PD allowance — so the kit charges under PD but the substation building may not. Second, change of use: bolting a few staff chargers onto a workplace car park is not a use change; turning a quiet asset into a destination public charging hub, with signage and traffic drawn in specifically to charge, can be — and LPAs are increasingly alert to it. If public charging is your commercial model, factor a use-class conversation in early. This is one of the questions worth settling before you decide between a funded versus owner-operated route, because a CPO partner will have a view on who carries the planning risk.

Building Regulations Part S — the rule people forget

Planning permission and Building Regulations are two separate consent regimes, and it’s Part S that trips up new-build and refurbishment schemes.

Approved Document S (England), in force since 15 June 2022, applies to new buildings and major renovations with associated parking. For non-residential development:

• More than 10 parking spaces → at least 1 chargepoint must be installed, and
• Cable routes (the ducting/containment for future chargers) provided for 1 in 5 of the total spaces.

There is a £3,600-per-connection cost exemption cap: where the cost of meeting the requirement for a given connection exceeds £3,600, the obligation is limited accordingly (typically relevant where grid or civils costs are exceptional). Part S bites at the point you are building or substantially renovating a car park regardless of whether the chargers themselves need planning — so a scheme can be PD for planning yet still legally obliged to provide chargepoints and passive infrastructure under Building Regs. Getting the passive cable routes in during construction is dramatically cheaper than retrofitting trenching later; it’s one of the biggest single levers on future installation cost.

The realistic decision path

For a typical existing commercial car park, the sequence is:

1. Are you altering or extending the car park (new build / major renovation)? If yes, Part S applies — design in the chargepoint(s) and 1-in-5 cable routes now.
2. Is the site listed, in a conservation area, National Park/AONB, or under an Article 4 Direction? If yes, assume you need to apply and budget the time.
3. Are all units within PD limits (upstands ≤2.7m, or ≤1.6m near homes/highway; wall units <0.2 m³; one cabinet ≤29 m³)? If yes, and there’s no change of use, you’re very likely PD.
4. Any doubt? Apply for a Lawful Development Certificate (LDC). It’s cheaper and faster than a full application, and it gives you a binding written confirmation from the LPA that the works are lawful — invaluable when a landlord, funder or future buyer asks for proof.

The LDC route is the honest answer to “are we sure?”. Many experienced installers will recommend it for anything borderline — near a residential boundary, on a mixed-use estate, or where a cabinet is close to the 29 m³ line — because it converts an assumption into a document.

A note on covered and multi-storey car parks

Planning is only half the picture in enclosed structures. Government interim fire guidance (July 2023) asks for a competent fire risk assessment before installing chargepoints in covered or underground car parks, and confirms sprinklers are effective. That’s a Building Safety / fire-safety obligation running alongside planning, not a substitute for it — and it can influence siting (and therefore whether a unit stays within PD). Retail, hotel and workplace decks with residential above them carry both the 1.6m near-dwellings planning limit and the fire-assessment duty, so they warrant the most careful design. If that’s your setting, our retail and mixed-use car park guidance goes into the layout and utilisation trade-offs in more depth.

Grants and the bigger commercial question

Planning sits inside a wider feasibility picture. The consent route affects programme and cost, but so does funding: the Workplace Charging Scheme (up to £500/socket, 75% of cost, to 31 Mar 2027) covers workplace and staff/fleet bays, while public off-street parking looks instead to commercial models and, for councils, the LEVI fund. Our grants and funding guide breaks down what your specific car-park type can access, and whether the 100% First-Year Allowance is worth more to you than a grant. Before committing to hardware, it’s worth pressure-testing whether the numbers work at all — that’s the job of our honest look at whether car-park EV charging is worth it.

Bottom line

For most existing commercial car parks, standard AC and many DC installations fall within permitted development and need no planning application — provided you respect the height (2.7m, or 1.6m near homes), wall-unit volume (0.2 m³) and cabinet (29 m³) limits, and you’re not on protected or listed land or changing the site’s use. New and renovated car parks must separately meet Building Regs Part S. When it’s borderline, a Lawful Development Certificate turns “we think so” into a legal fact.

Frequently asked questions

Do I need planning permission to install EV chargers in my car park?

Usually no. Since 29 May 2025, free-standing chargepoint upstands up to 2.7m (or 1.6m near dwellings or a highway), wall units under 0.2 cubic metres, and one equipment cabinet up to 29 cubic metres are permitted development on off-street parking. You typically only need to apply if you exceed those limits, are on listed or protected land, are within an Article 4 Direction, or are changing the site’s use.

What is the height limit for an EV charger upstand under permitted development?

2.7 metres on standard off-street parking. However, where the upstand is within 2 metres of a highway or close to a dwelling, the limit drops to 1.6 metres. Exceeding the applicable limit takes the installation outside permitted development and into a full planning application.

Does Building Regulations Part S apply to my car park?

Approved Document S (England, in force 15 June 2022) applies to new buildings and major renovations. For non-residential development with more than 10 parking spaces, you must install at least 1 chargepoint plus cable routes for 1 in 5 spaces, subject to a £3,600-per-connection cost exemption cap. It is a separate regime from planning permission and can apply even when the chargers themselves are permitted development.

What if I’m not sure whether my installation needs planning permission?

Apply for a Lawful Development Certificate (LDC) from your local planning authority. It is cheaper and faster than a full application and gives you binding written confirmation that the works are lawful — useful evidence for landlords, funders and future buyers. It’s the recommended route for anything borderline, such as units near a residential boundary or a cabinet close to the 29 cubic metre limit.

Do covered or multi-storey car parks have extra requirements?

Yes. Government interim fire guidance from July 2023 asks for a competent fire risk assessment before installing chargepoints in covered or underground car parks, and confirms sprinklers are effective. This fire-safety duty runs alongside planning and Building Regulations rather than replacing them, and can influence where units are sited.
