EV chargers for car parks: what could your site earn?

Add chargers when your parking stays and electrical capacity support a credible demand forecast. DfT counted 121,171 public chargers across the UK in July 2026 [S1], but that does not establish demand for your bays. Compare fully funded host income with part funded and self funded returns, including displaced parking income and operating costs. Checked October 2026.

Could you make money from EV chargers in your car park?

Your site could earn charging income if enough drivers buy energy at a margin that covers operation. Parking occupancy alone does not measure that demand. Record arrival times, parking duration, repeat visitors and enquiries about charging. Check nearby availability and access restrictions during your actual opening hours.

DfT counted 121,171 UK public chargers on 1 July 2026 [S1]. Use that as national context, rather than a forecast for your car park. A busy station approach and a quiet overflow car park need different investment cases.

For a car-park operator, test the effect on pay-and-display turnover. For park-and-ride and station-car-park sites, test commuter stays and access outside transport operating hours. These business types need separate surveys; a shared postcode does not make their charging demand interchangeable.

How much does it cost to have an EV charging station?

Compare fully funded, part funded and self funded proposals using the same bay plan and connection scope. Our commercial cost guide explains the quote headings to request.

Ask each bidder to state the proposed term, exclusivity area, electricity payer, maintenance scope and termination cost. There is no assumed standard lease length here. Ask your solicitor to check access rights, redevelopment, insolvency and removal. Compare funding versus buying before signing.

An illustration, not a quote

Every input below is an assumption, not an observed installation price or offered revenue share. kW means kilowatts, a measure of power. kWh means kilowatt-hours, a measure of energy. Sessions are totals across the site.

Assume energy cost includes charging losses. Annual energy = sessions × 15 × 365. Sales = energy × £0.50. Operating net = energy × (£0.50 − £0.25) − £1,000. Fully funded income = sales × 10%. Part funded net = operating net × 50%. Simple ROI = annual host net ÷ host capital × 100%; payback = host capital ÷ annual host net.

Results are rounded after calculation. Matching ROI follows from the assumed equal capital and net split; it is not an expected feature of commercial offers. At central capital, mid-use self funded payback is £15,000 ÷ £4,475 = 3.35 years. Fully funded has no host capital to recover, so compare annual receipts and land commitment.

These figures exclude VAT, tax, borrowing, major replacements, new grid works and lost parking revenue. Deduct your displaced parking contribution before recalculating returns. Read the payback guide for sensitivity checks.

How do you charge for EV charging?

Publish a clear energy tariff alongside your parking terms. State whether charging buys any parking time, whether a driver must register the vehicle and what happens when charging ends. Test the signs with someone unfamiliar with the site. A successful charging payment should not leave them guessing about a parking ticket.

The public charging rules require price transparency in pence per kWh. Contactless duties cover new public units of at least 8 kW deployed after 24 November 2024 and existing units of at least 50 kW, subject to the regulations’ scope and exemptions [S2].

For an in-scope operator, reference and availability data must be open and machine-readable using the Open Charge Point Interface. Availability changes must appear within 30 seconds. The guidance includes a micro-business exemption from requirements other than pricing [S3]. Get a scope assessment from your solicitor; allocating work in a contract does not itself settle who is legally responsible.

What could it cost to add solar carports?

Obtain a separate canopy design and quote. Keep its foundations, drainage, lighting and lost parking costs out of the charger-only illustration until priced. Compare solar consumed on site with export income rather than valuing all generation at the retail electricity price.

England has a conditional permitted development route for solar canopies in non-domestic off-street car parks, with prior approval for siting, design and appearance [S4]. Ask the planning authority about your site; check the relevant national rules elsewhere. Review solar and battery returns.

For chargers, request a supply survey, cable route and accessible bay layout before fixing the position. Ask about lighting, cable handling and a step-free route to the payment equipment. Have your accountant assess possible business rates changes. WCS is not a general customer-car-park subsidy; check the use restrictions [S5].
