Should your Wokingham workplace add chargers, solar or batteries?

Wokingham had 297 public chargers on 1 July 2026 [S1]. For your workplace, reliable access during a shift matters more than the borough total. Mereoak's proposed solar and battery scheme provides local context, but its scale is different from a staff car park. Test a charging-only budget before adding generation or storage. Checked October 2026.

How would six shared workplace sockets perform at different use levels?

Here is an illustration, not a quote, for six 7 kW alternating-current (AC) chargers. Kilowatts (kW) measure power; kilowatt-hours (kWh) measure delivered energy. Use levels below are assumptions for a working-day model, not measured Wokingham utilisation.

Input Budget basis or assumption
Sessions per socket each working day, low / mid / high 0.25 / 0.75 / 1.25
Working days / energy per session 250 a year / 12 kWh
Driver price / purchased electricity £0.45 / £0.25 per kWh
Annual software and maintenance, whole site £1,200
Six chargers at £1,200–£2,000 £7,200–£12,000 [S5]
Shared infrastructure £3,000–£8,000 [S5]
Base capital total £10,200–£20,000
Groundworks, cable runs and connection Extra, excluded
fully funded host share 8% of sales
part funded capital / surplus share 50% / 60%
self funded capital / surplus share 100% / 100%

Ask what shared infrastructure includes and separate additional works [S6]. Energy = 6 × sessions × 250 × 12; surplus = energy × £0.20 − £1,200. Mid use gives 13,500 kWh, £6,075 sales and £3,375 electricity cost: £1,500 remains after overhead.

Host result per year Low Mid High
fully funded income £162 £486 £810
part funded net income −£180 £900 £1,980
part funded simple ROI −3.5 to −1.8% 9.0–17.6% 19.8–38.8%
part funded payback, years None at a loss 5.7–11.1 2.6–5.1
self funded net income −£300 £1,500 £3,300
self funded simple ROI −2.9 to −1.5% 7.5–14.7% 16.5–32.4%
self funded payback, years None at a loss 6.8–13.3 3.1–6.1

Fully funded assumes the provider pays, installs, owns and operates. Part funded splits capital equally and gives you 60% of surplus or loss. Self funded makes you responsible for capital and leaves you the operating result. No provider offer is implied by those shares.

Return on investment (ROI) = host net ÷ host capital × 100. Payback = capital ÷ positive net. VAT, finance, tax, payment fees, replacement equipment and parking opportunity cost are excluded. Grants are not deducted. Use the income and payback calculator after adding the full infrastructure quotation.

Should a workplace copy the Mereoak solar-and-storage proposal?

Mereoak Park and Ride, just off the A33, is the council’s proposed local example of charging combined with solar canopies and battery storage. The council describes a mixture of rapid and standard charging and says the site suits both shorter and longer stays [S3]. Treat it as a proposal with its own parking pattern, not an income benchmark for your premises.

Your first task is to separate staff energy needs from a possible public charging business. Then ask whether solar output would coincide with that demand and what a battery would actually do. Request distinct budgets for charging, solar and storage so each investment can be assessed. Start with workplace charging and the site-power tool.

How much charging is already available around Wokingham?

Public chargers per 100,000 people, 1 July 2026 Wokingham South East UK
All power bands 158.7 159.4 174.9
Rapid-or-above 36.9 39.7 41.7

The borough count includes 69 rapid-or-above chargers [S1]. Overall provision is close to the regional rate, while rapid provision is below both comparisons. A borough-wide rate cannot tell you whether a staff member has charging available during their working day.

To derive the comparison rates, infer council populations as count ÷ published rate × 100,000. Sum charger counts and inferred populations, then calculate chargers per 100,000. Rounding makes these regional and UK results approximate. The South East page gives wider context, and Woodley narrows the geographical question.

Wokingham recorded 9,340 licensed plug-ins in 2026 Q2: 6,088 battery-electric and 8,175 privately kept plug-ins [S2]. Keeper-address figures can include fleets; they do not establish demand from your employees. Survey actual commute patterns and charging requests before deciding how many bays to reserve.

How do you keep shared bays useful without overloading the supply?

Check SSEN’s local-authority network map [S4], then confirm your address and supply with your distribution network operator (DNO), the organisation responsible for local cables. Ask how load management would allocate power when the building is busy. A nameplate rating does not establish spare import capacity.

Set an access and handover policy before installation. Decide how staff reserve bays, who can move a vehicle and what happens during holidays or faults. Check accessible routes and cable handling. If charging opens to the public, review the scope of the public regulations [S9].

Ask your solicitor to review planning, landlord consent, lease length, exit rights, reinstatement, insurance, liability and business-rates allocation. Write down support and maintenance obligations. Check WCS eligibility [S7] and discuss capital allowances with your accountant [S8].

Turn staff demand into a Wokingham enquiry

Collect a staff survey, supply bill, parking layout and separate solar or storage objectives. Piggy Pineapple Ltd operates this advice and referral service. We refer enquiries to installer partners and may be paid a fee. We name the recipient and disclose any owner shareholding in that company before passing details on. Read how we work and get matched with an installer that covers your area.

How many plug-in vehicles share each public charger here?

Wokingham has 27.5 privately kept plug-in vehicles for every public charger, ranked 63 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 Wokingham grew 36% 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.

Vehicles are counted where the keeper lives, and drivers with a driveway often charge at home. Use this as a first screen, not a forecast. Chargers as at 1 July 2026; vehicles as at 2026 Q2.

Public charging funding: Wokingham has £264,000 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 are commercial buildings here rated?

Of the non-domestic energy certificates lodged in Wokingham over the last ten years, 3% are rated F or G (below the minimum for letting) and 10.7% are rated E (England and Wales: 3% and 12.4%).

Certificates lodged 2016 Q3 to 2026 Q2.

See every council and the rules, or read EPC and MEES for commercial landlords.

How much electricity do businesses here use?

Wokingham had 4,753 business electricity meters in 2024, using 276 GWh between them. The middle business meter used 8,142 kWh in the year (Great Britain: 6,934 kWh); a few large users pull the average much higher.

At the end of 2025, Wokingham had 5,883 solar PV installations on homes and businesses, 58.5 MW in total: 9% more capacity than at the end of 2024. Solar cost and payback in this region.

Common questions

Does the council's project mean every site needs batteries?

No. The council proposes batteries alongside solar canopies at Mereoak [S3]. Request separate charging-only and combined designs for your site; the workplace illustration includes neither solar nor storage.

Can staff bays stay outside public charging regulation?

DfT excludes workplace charging that is never accessible to the public [S9]. Document access controls and reconsider the assessment if you later admit customers or residents.

How many sockets can one WCS applicant claim for?

The cap is 40 sockets across all applicant sites, with up to £500 per eligible socket [S7]. The award is not automatic; do not deduct it until eligibility and the application route are confirmed.

Is the WCS grant already included in the capital budget?

No. The model shows costs before grants. WCS covers up to 75% of eligible costs, subject to its caps and the scheme end date of 31 March 2027 [S7].

Does capital allowance relief shorten the quoted payback?

The table excludes tax. HMRC lists qualifying new charging equipment bought before April 2027 for 100% first-year allowances [S8]. Check with your accountant before modelling any after-tax return.
