How to Choose an EV Charger Installer and Compare Apartment Quotes

Two apartment charging quotes are comparable only when they describe the same site, equipment, electrical assumptions, construction work, approvals, and ongoing service. A lower total can reflect a smaller scope: one proposal may include utility coordination and inspection records while another assumes that the building will arrange them separately.

Confirm the installer fits the work

Ask each bidder to identify the person or company responsible for the electrical design, permit application, utility coordination, construction, inspection, and final records. Verify the relevant licence or registration through the authority for the project location. Training, references, and experience with occupied multi-unit buildings can help you compare bidders, but they do not replace local licensing or approval.

The U.S. Department of Energy recommends involving the utility and an electrical contractor familiar with applicable codes and permits. Canada’s NRCan installation guide describes building, tenant, strata, and contractor coordination. In Ontario, ESA identifies the Licensed Electrical Contractor and ESA process. In Great Britain, an OZEV authorised-installer status is relevant when a named OZEV grant is being claimed; it should not be treated as a substitute for checking the qualifications and responsibilities required for other work.

Give every bidder the same site brief

Share the same available information and invite each bidder to identify what they still need to inspect. The brief should state:

• The parking spaces, ownership or assignment, and who can approve work on them.
• Whether the garage is underground, detached, outdoor, shared, or subject to controlled access.
• Known electrical drawings, panel schedules, service information, and prior assessments, with their dates and limitations.
• The route from the proposed equipment to the electrical supply, including walls, floors, fire-resisting assemblies, vehicle paths, pedestrian routes, and access restrictions.
• Expected current and future charging use, metering or network needs, accessibility needs, and the party that will operate and maintain the service.
• Any authority, utility, property, grant, or schedule constraints already known.

Do not ask a resident to inspect live equipment or produce an electrical calculation. The qualified bidder should survey conditions and list assumptions that cannot yet be verified.

Compare the complete scope

Scope item	Questions to ask each bidder	What to compare
Equipment	What make, model, quantity, connector, rated output, network, and payment features are included?	Same equipment class and eligibility assumptions, with model changes priced clearly.
Electrical assessment	Who checks service and panel capacity, existing loads, future demand, metering, load management, or an upgrade?	Named professional, stated assumptions, deliverables, and separately priced utility or upgrade work.
Route and construction	Which cable or conduit route, penetrations, surface work, protection, patching, signage, and access arrangements are included?	Marked route, identified exclusions, and treatment of fire, structural, water, and parking constraints.
Approvals	Who confirms property approval, utility requirements, permits, inspections, and building or fire reviews?	A responsibility matrix and a schedule that does not assume unconfirmed approval.
Commissioning	What operation, safety, network, meter, access, and support checks are included?	Named tests or demonstrations, sign-off roles, and the handover records.
Price and changes	What are equipment, labour, design, civil work, permits, network, and recurring costs? What can trigger a change order?	Itemized price, allowances, assumptions, taxes, expiry date, and written change control.
Warranty and support	Who handles equipment faults, electrical defects, software or network problems, and maintenance?	Warranty term, exclusions, response contact, service contract, and which party pays.

Request an itemized proposal that separates charger purchase from common infrastructure and from recurring network or maintenance charges. Confirm whether the quote includes drawings, service upgrades, fire or structural review, accessible-space work, permits, utility fees, tax, resident notices, inspections, and restoration of affected areas. Ask what is explicitly excluded and what will happen if the site survey changes the assumed route.

Check program requirements before comparing price

Some utilities and public funding programs require applications, eligible equipment, site assessments, particular records, or inspections on a specific schedule. Those requirements belong to that program and can change. If the building expects a rebate or grant, ask who verifies current terms and who submits the evidence. Do not assume a past award, quote, or equipment list remains valid.

Warning signs to resolve

• The bidder promises that no permit or inspection is required without naming the authority or basis.
• The proposal has no site survey, route, electrical assumptions, or equipment identity.
• A capacity or fire question is answered with an unqualified guess.
• The price omits utility work, penetrations, protection, networking, permits, or recurring charges without stating that those items are excluded.
• No party accepts responsibility for the permit, test records, commissioning, or support after residents begin charging.
• A bidder pressures the building to approve before written permission, current program approval, or required professional review is settled.

Score each proposal against the same scope and keep the open questions beside the price. Then compare total project and operating obligations, not just the charger or a single installation line. For the document list an authority may request, see the apartment permit-package guide; for a complete path through the project, see the installation sequence.
