Business EV charging in Thurrock: can rapid charging pay back?

Thurrock had 208 public chargers on 1 July 2026 [S1]. Public provision per resident was below the regional rate, although rapid provision was higher. A commercial site needs a clearer case than that comparison: who will charge, when they can enter, and whether its electricity supply supports the proposal. Include connection costs before judging payback. Checked October 2026.

What does a rapid charger cost once the supply is included?

A short-stop customer proposal should survive a connection-cost test. The opened cost references together give an installed range of £15,000–£45,000 for one 50 kW direct-current (DC) charger, excluding grid connection. [S8] [S9] A main supply upgrade is a separate £40,000–£150,000 budgeting line in the cost reference. [S8] A kilowatt (kW) measures power; a kilowatt hour (kWh) measures delivered energy.

The following assumes a business car park seeking public short-stop use. It is an illustration, not a quote, with no claim about actual Thurrock utilisation.

Apart from the cited equipment and upgrade ranges, these are assumptions. The capital range holds the assumed upgrade constant; a larger connection quotation increases it. Ask for separate groundworks, cable runs and connection items, and add anything outside the assumed scope. [S9]

Mid-case energy = 5 × 365 × 30 = 54,750 kWh. Net = 54,750 × (£0.70 − £0.30) − £2,000 = £19,900. Fully funded income = 54,750 × £0.70 × 10% = £3,832.50; part funded host net = £19,900 × 60% = £11,940. Simple return on investment (ROI) = host net ÷ host capital × 100; payback years = host capital ÷ host net.

At high use, the £30,000 charger-only calculation would exceed 100% annual ROI: £33,040 ÷ £30,000 × 100 = 110.1%. Including the supply upgrade reduces that to 47.2%. All returns above include the upgrade. They exclude VAT, tax, finance, losses, payment fees, rates, insurance and replacement. Recalculate using the income and payback tool.

How does Thurrock’s public charging compare with the wider market?

The 1 July 2026 public total included 104 rapid-or-above chargers, meaning rated at least 50 kW. [S1]

Aggregate rates use the supplied council dataset: infer population as chargers × 100,000 ÷ local rate, sum populations and counts, then recalculate rates. These approximations inherit rounded council rates. [S1] The rapid rate is above both benchmarks, so a lower overall rate is not evidence that any new rapid site will fill.

Thurrock recorded 5,737 plug-in vehicles in 2026 Q2, including 3,108 battery electric vehicles; 4,414 plug-in vehicles were privately kept. Registrations describe keepers, not traffic through your entrance. [S2] Compare the East of England context before narrowing your catchment.

Where could your business serve a different charging need?

The council lists standard-power charging in Grays, Tilbury, Corringham, South Ockendon and Aveley. [S3] Its public rollout prioritises residents who cannot charge at home. [S10] These locations help you test a customer proposition, but residential provision does not show fleet demand.

For a Grays business, compare entrance access, parking restrictions and actual charging availability at the hours your customers visit. For fleets and depots, begin with vehicle return times and required departure energy. For retail, measure visits long enough to charge and preserve delivery routes. Keep those uses separate when estimating sessions.

Who pays for the grid, parking and operating obligations?

Use UK Power Networks’ own coverage map and postcode checker to confirm your distribution network operator (DNO). [S4] Obtain a supply assessment before treating the assumed upgrade budget as workable.

Under fully funded, the provider pays, owns and operates while you provide space and receive the agreed share. Part funded shares capital; self funded makes you responsible for the investment and operating budget. Specify responsibility for connection overruns, repairs, vandalism, liability, rates and reinstatement. Have your solicitor check lease length, assignment, exit and redevelopment rights, plus the planning route.

For public access, the operator must meet the Public Charge Point Regulations 2023. Staff-only use has a different scope under regulation 3; check with your solicitor. [S6] Do not describe a legal duty as an optional service benefit.

What support belongs in a workplace budget?

WCS currently offers eligible installations up to £500 per socket and closes on 31 March 2027. [S5] The workplace grant guide helps distinguish workplace provision from a public customer project. No award is assumed above. HMRC’s chargepoint allowance extension runs to March 2027 for Corporation Tax and April 2027 for Income Tax; check with your accountant. [S7]
