How should a Windsor and Maidenhead business plan EV charging?
Windsor and Maidenhead had 238 public chargers on 1 July 2026 [S1]. The much larger licensed plug-in vehicle total is a keeper-address statistic, not a count of local customers. Test parking access and actual guest or staff requests, then compare fully funded income with part funded and self funded returns. Checked October 2026.
Can drivers actually reach an available charging bay?
The borough’s charging-bay consultation reports existing chargers being obstructed by vehicles that are not charging. Its outcome proposes dedicated bays on Albert Street and Alma Road in Windsor and College Road in Maidenhead, among other locations. It says a legal consultation is required before implementation [S3]. Do not describe these proposals as completed parking restrictions.
That makes access a useful starting point for your own business. A charger behind a locked gate, beside a delivery route or in a bay occupied all day may serve fewer people than the equipment specification suggests. Check Windsor and Maidenhead separately rather than treating the borough as a single catchment.
Does the vehicle count represent your potential customers?
In 2026 Q2, the borough recorded 267,700 licensed plug-ins, including 206,469 battery-electric vehicles. Privately kept plug-ins numbered 5,973 [S2]. Fleet vehicles are recorded at their keeper address. The total therefore cannot be converted into a local population of drivers seeking a charge at your site.
Ask employees and guests what they need instead. Record whether they can charge elsewhere, when they arrive and how long they park. A visitor asking to reserve a charger is more relevant to your access plan than a large registration total. The hotel sector and office sector address different patterns of use.
| Public provision at 1 July 2026 | Borough | South East | UK |
|---|---|---|---|
| All chargers per 100,000 people | 149.7 | 159.4 | 174.9 |
| Rapid-or-above per 100,000 people | 15.1 | 39.7 | 41.7 |
There were 24 rapid-or-above chargers [S1]. Both rates fall below the comparisons; this does not establish a commercial shortage beside your property. Regional and UK figures are approximate council-row calculations: infer population as count ÷ rate × 100,000, then divide summed counts by summed populations. Published input rates are rounded. See the South East context.
Could a small guest installation repay its cost?
Consider three 7 kW alternating-current (AC) chargers at a hypothetical accommodation site. Kilowatts (kW) describe power; kilowatt-hours (kWh) describe energy. This is an illustration, not a quote, with assumed occupancy and charging purchases rather than a borough demand forecast.
| Input | Assumption or capital basis |
|---|---|
| Sessions per charger daily, low / mid / high | 0.2 / 0.6 / 1.0 |
| Available days / energy per session | 365 a year / 15 kWh |
| Driver price / energy cost | £0.55 / £0.25 per kWh |
| Annual software and maintenance, all units | £900 |
| Three chargers at £1,400–£2,500 each | £4,200–£7,500 [S5] |
| Groundworks, cable runs and connection | Extra, excluded |
| fully funded host income share | 10% of sales |
| part funded capital / operating share | 50% / 60% |
| self funded capital / operating share | 100% / 100% |
Use the published charger range as a starting budget and obtain a separate infrastructure scope [S5], [S6]. Annual energy = 3 × sessions × 365 × 15. Surplus = energy × £0.30 − £900. Mid use gives 9,855 kWh: £5,420.25 sales − £2,463.75 electricity − £900 = £2,056.50.
| Annual host result, rounded | Low | Mid | High |
|---|---|---|---|
| fully funded income | £181 | £542 | £903 |
| part funded net income | £51 | £1,234 | £2,417 |
| part funded simple ROI | 1.4–2.4% | 32.9–58.8% | 64.5–115.1% |
| part funded payback, years | 40.9–73.1 | 1.7–3.0 | 0.9–1.6 |
| self funded net income | £86 | £2,057 | £4,028 |
| self funded simple ROI | 1.1–2.0% | 27.4–49.0% | 53.7–95.9% |
| self funded payback, years | 49.1–87.7 | 2.0–3.6 | 1.0–1.9 |
Fully funded puts installation, ownership and operation with the provider. Part funded assumes an equal capital split and allocates 60% of operating surplus to you; self funded gives you the whole operating result and cost. Contract availability is unproven. ROI, or return on investment, = host net ÷ capital × 100; payback = capital ÷ net, using unrounded results.
The model excludes VAT, finance, tax, payment fees, replacement equipment and parking value. Low-use returns are too thin to absorb much extra cost. Enter a complete quotation in the payback tool.
What should be resolved before reserving guest parking?
Use SSEN’s own local-authority coverage map to start the supply check [S4]. Your distribution network operator (DNO) manages local cables; confirm the exact address and proposed load. Ask for a managed-power design and a priced cable route rather than assuming every charger runs at full power together.
Agree booking, signage, accessible routes and what happens when a guest stays connected after charging. Put maintenance, damage, insurance and driver support into the operating agreement. Have your solicitor check planning, lease duration, break clauses, redevelopment, end-of-term removal and business-rates responsibility. Check WCS eligibility [S7] and capital allowances with your accountant [S8]; neither is deducted above. Review the public charging rules against your access policy [S9].

How many plug-in vehicles share each public charger here?
Windsor and Maidenhead has 25.1 privately kept plug-in vehicles for every public charger, ranked 92 of 357 UK councils (1 = most vehicles per charger). The UK figure is 13.1; the middle council has 17.8.
Privately kept plug-in vehicles in Windsor and Maidenhead grew 28% from 2025 Q2 to 2026 Q2 (UK: 43%).
That is more than most councils, which can point to demand that public charging does not yet meet, especially where many homes have no driveway.
Public charging funding: Windsor and Maidenhead has £927,000 of Local Electric Vehicle Infrastructure (LEVI) capital funding (approved for delivery). LEVI is aimed mainly at areas where many homes have no off-street parking, and the authority chooses the operators and sites. LEVI allocations (GOV.UK)

How much spare grid capacity is there here?
Open data from SSEN Distribution lists 9 bulk supply and primary substations in Windsor and Maidenhead. For new demand such as chargers, 8 are green (spare capacity), 0 amber and 1 red. Maidenhead BSP reports the most spare demand capacity, about 23.2 MVA.
Spare capacity varies street by street. Check the substations nearest your site with the grid capacity lookup.
Common questions
Can guests-only parking still count as public charging?
DfT includes publicly accessible hotel car parks within its examples [S9]. Restricting opening hours does not by itself remove public status. Check the access model and applicable exemptions with your solicitor.
Is a contactless terminal compulsory on a new 7 kW charger?
The contactless threshold for new public equipment is 8 kW per cable [S9]. A 7 kW unit is below that threshold, but other public charging duties can still apply.
How much workplace support is available per socket?
WCS caps support at £500 per eligible socket and 75% of eligible costs [S7]. A hotel should confirm applicant and access conditions before assuming guest charging qualifies.
Can tax relief be counted as charging income?
No. HMRC's 100% first-year allowance concerns qualifying new equipment bought before April 2027 [S8]. It is not charging sales; check with your accountant before changing the investment calculation.
Does public parking evidence show a need for overnight chargers?
The council consultation identifies obstruction of existing charging bays [S3]. It does not measure overnight hotel demand. Record guest requests, arrival times and energy needs before selecting equipment.
