Maidenhead EV charging: is the listed supply enough?

Maidenhead has 7 public charging sites listed on Open Charge Map in the supplied town inventory [S1]. That sparse record deserves a local check before investment: it may miss facilities and says nothing about queues. A host should identify staff, visitor or resident demand that its parking can serve, then model fully funded income alongside part funded and self funded payback. Checked October 2026.

What might Maidenhead’s listed charging gap mean?

The supplied built-up-area extract records 7 public sites listed on Open Charge Map, containing 18 devices and 1 rapid site. [S1] With 67,391 Census-derived residents, the calculated density is 1.0 site and 2.7 devices per 10,000 residents. [S2] [S3]

A business could investigate whether its parking adds a useful location, a different opening period or access for customers poorly served elsewhere. Those are possible services to test. The count alone does not show unmet demand or prove that drivers will accept your price.

Open Charge Map is community-maintained and lists fewer points than the DfT council count. Its town listings are not an official total. Confirm provision on the ground with the local charging tool, including restrictions that a map marker may not explain.

Do A404(M) traffic and local visits support your proposal?

Maidenhead’s supplied busiest-major-road selection is the A404(M), carrying 65,651 vehicles daily in the 2025 DfT extract. [S4] That is road-link traffic, not a count of people able or willing to enter your premises. Check the route from the relevant junction before assigning any value to passing trade.

Transport for London identifies Maidenhead station as an Elizabeth line stop with a car park. [S11] Norden Farm Centre for the Arts is on Altwood Road and describes its own parking for visitors. [S12] Rail journeys and arts visits create different parking patterns: a commuter may leave a vehicle for the working day, while an event concentrates arrivals and departures.

For your own site, observe the hours when bays are occupied and when electricity demand peaks. Do not assume that nearby cultural or rail visitors can use private workplace parking. Access, walking routes and permission need checking alongside price.

Which hosts benefit, and what could an office earn?

An office can begin with repeat staff demand rather than traffic capture. Kilowatts (kW) measure instantaneous power; kilowatt hours (kWh) measure delivered energy. This hypothetical office uses alternating current (AC) charging during the working day.

An illustration, not a quote. The reference for two units is twice the published single 7 kW workplace band of £1,400–£2,500. [S7] All other inputs below are assumptions.

Extra groundworks, cable runs and connection sit outside the charger reference. Replace the assumed £2,500 with a surveyed specification. Quotations should also expose recurring charges. [S8] Amounts are modelled excluding VAT, without grant support.

The mid case delivers 3 × 16 × 250 = 12,000 kWh. Multiply by £0.50 for £6,000 sales; deduct £3,000 electricity and £600 annual costs to leave £2,400. Fully funded pays sales × 10%; part funded pays surplus × 60%. Return on investment (ROI) = net income ÷ host capital × 100. For simple payback, divide host capital by annual net income.

Fully funded makes the operator responsible for investment, ownership and operation while you provide bays. Part funded shares that initial expenditure equally in this model. Self funded retains the operating surplus and commits the full investment. A low-use office may not attract a fully funded offer at all.

The example omits borrowing, tax, replacement, energy losses, business rates and lost parking income. Use the income calculator to stress-test lower attendance or a smaller tariff.

Which grants and permissions should an office check?

WCS offers up to £500 per socket, with a 31 March 2027 closing date. [S6] Confirm parking eligibility before including any award in your budget.

HMRC’s 100% first-year allowance includes qualifying new chargepoint equipment bought before April 2027; check with your accountant. [S9] Public access adds pricing obligations under the Regulations. [S10] Seek a solicitor’s review of liability, access hours, contract duration, early exit and reinstatement.

Arrange planning and accessibility checks and a supply assessment through the distribution network operator (DNO), responsible for local electricity connections. The office’s existing connection does not itself establish spare capacity.

How does Maidenhead relate to the wider borough?

DfT’s supplied council return has 238 public chargers, including 24 rapid or above, on 1 July 2026. [S5] The Windsor and Maidenhead overview covers that wider geography. Maidenhead’s supplied population share is about 42% of the borough comparison population. [S2]

Consult the South East summary without treating regional density as a forecast for your office. The town map and council inventory have different coverage and should not be subtracted.

Review the office charging case and WCS guidance for the staff-parking proposal. Windsor’s visitor-led assessment illustrates a different use pattern within the borough.
