Can overnight EV charging work for a Bath area business?

Bath and North East Somerset had 179 public chargers on 1 July 2026 [S1]. An overnight guest or community charging offer needs a parking policy as well as equipment. Compare local alternatives, confirm power and test low use before investing. Fully funded income and part funded or self funded payback depend on the agreed costs and shares. Checked October 2026.

What must you agree before leaving the charger open overnight?

National Grid Electricity Distribution’s area map and postcode lookup are the starting point for this South West supply enquiry [S4]. Confirm the exact address with your distribution network operator (DNO), which manages local electricity cables. Ask for a load assessment before ordering equipment.

Test lighting, accessible routes, cable position, gates and emergency access. Decide whether residents can use the same bay as guests and how they find support outside reception hours. Public access can bring public charging obligations even on private land [S9].

Take planning, landlord consent, lease length, exit rights, removal, insurance, liability and business-rates allocation to your solicitor. Specify maintenance duties in writing. WCS is subject to eligibility [S7]; capital allowances need an accountant’s assessment [S8]. Neither benefit appears in the example.

Could overnight access solve a different problem from daytime charging?

The council’s parking consultation proposes removing the overnight maximum charging stay at Larkhall Square car park. It explains that this would support residents where off-street parking is limited [S3]. This is a proposed change, not confirmation of current parking terms. The council also publishes an on-street charging strategy focused on public demand and opportunities to improve provision [S10].

For your business, the useful question is whether charging can happen while someone is already parked. A guest staying overnight and a customer stopping briefly have different needs. A community venue might test evening access, but it must consider who handles faults after the building closes.

Use the Bath page for the city, then assess your own catchment. The accommodation sector and community sector suggest different operating questions.

How far below regional provision is the council area?

At 1 July 2026, chargers per 100,000 people Council area South West UK
All public chargers 89.5 156.7 174.9
Rapid-or-above chargers 17.5 49.5 41.7

The total includes 35 rapid-or-above chargers [S1]. Both population rates are below the comparison figures. This supports further investigation, not an assumption that any available bay will attract paid sessions.

Comparisons are approximate calculations from council rows. Infer population as charger count ÷ published rate × 100,000; sum populations and charger counts before calculating the aggregate rate. Rounded council rates limit precision. The South West overview provides broader context.

The area had 6,189 licensed plug-ins in 2026 Q2, including 4,130 battery-electric vehicles and 5,257 privately kept plug-ins [S2]. Vehicles are attributed to keeper addresses, including fleets. That does not measure visitor arrivals, charging requests or the number of residents who would choose your car park.

Would one overnight socket cover its costs?

Consider a hypothetical small accommodation business testing one 7 kW alternating-current (AC) charger. Kilowatts (kW) measure power; kilowatt-hours (kWh) measure energy. This is an illustration, not a quote, intended to show the sensitivity to use before expanding the installation.

Input Assumption or published budget
Sessions daily, low / mid / high 0.25 / 0.75 / 1.5
Available days / energy per session 365 a year / 20 kWh
Driver price / purchased electricity £0.50 / £0.25 per kWh
Software and maintenance £300 annually
One installed 7 kW charger £1,400–£2,500 [S5]
Groundworks, cable runs and connection Extra, excluded
fully funded host share 10% of sales
part funded capital / operating share 50% / 60%
self funded capital / operating share 100% / 100%

The charger budget is a commercial reference, not a local survey price [S5]. Itemise the additional work rather than treating the equipment figure as the whole project [S6]. Annual energy = sessions × 365 × 20. Surplus = energy × £0.25 − £300. Mid use produces 5,475 kWh: £2,737.50 sales less £1,368.75 electricity and £300 overhead leaves £1,068.75.

Annual host result, rounded Low Mid High
fully funded income £91 £274 £548
part funded net income £94 £641 £1,463
part funded simple ROI 7.5–13.4% 51.3–91.6% 117.0–208.9%
part funded payback, years 7.5–13.3 1.1–1.9 0.5–0.9
self funded net income £156 £1,069 £2,438
self funded simple ROI 6.3–11.2% 42.8–76.3% 97.5–174.1%
self funded payback, years 9.0–16.0 1.3–2.3 0.6–1.0

Fully funded assumes the provider pays, installs, owns and operates, giving you the sales share. Part funded assumes equal capital contributions and 60% of surplus to you; self funded leaves all costs and net income with you. These assumed arrangements may not be offered for a small site.

Return on investment (ROI) = host annual net ÷ host capital × 100. Payback = capital ÷ net, using unrounded figures. High use needs vehicle turnover; it cannot be assumed from overnight bookings alone. VAT, tax, finance, payment fees, equipment replacement and parking value are excluded. Add extra works in the income and payback tool before relying on these returns.

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

Bath and North East Somerset has 29.4 privately kept plug-in vehicles for every public charger, ranked 48 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 Bath and North East Somerset 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.

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: West of England CA has £6,644,000 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)

Common questions

Is the proposed Larkhall overnight change already in force?

The council page presents removal of the overnight maximum stay as a proposal [S3]. Check current signs and the adopted order before describing it as an operating rule.

Does limited opening time make a charger private?

No. DfT says a publicly accessible charger can remain public with restricted hours [S9]. Determine the applicable operator duties and exemptions before advertising access.

How much energy can the example deliver during a stay?

Its assumed 20 kWh session divided by 7 kW gives about 2.9 hours before losses or vehicle limits. The installed charger budget comes from the commercial cost reference [S5]; session size is an assumption.

Can a grant fund an overnight guest charger?

WCS applicant and access conditions must be checked. The headline support is up to £500 per eligible socket, capped at 75% of eligible costs, and the scheme ends on 31 March 2027 [S7].

Is an allowance a refund of the equipment price?

No. An allowance is a tax deduction subject to eligibility, not a cash repayment of the bill. HMRC lists qualifying new charging equipment bought before April 2027 [S8]. Check with your accountant.
