Electrical services and costs in Renfrew
Renfrew homeowners usually start thinking about electrical work when they notice the house can’t keep up—more appliances, higher heating demands, and now EV charging. With 8,190 people in the community (Statistics Canada, 2021 Census) and 58.5% of households owning their homes, many properties are long-term homes where upgrades are planned during renovations rather than at move-in. That’s important because 76.4% of dwellings were built before 1981 (Statistics Canada, 2021 Census), and older wiring and older panel/service sizes are exactly where problems surface first.
In the Kingston–Pembroke region, pricing is shaped by a large inventory of pre-1970 housing and a common need to replace knob-and-tube and address aluminum branch wiring. Many homes were built around 60A or 100A services, and today’s loads—heat pumps, baseboard/electric heat support, induction stoves, dryers, and growing EV demand—push capacity. That capacity review work is time-consuming and often leads to a panel and service upgrade, not just a “quick fix.”
Renfrew’s colder winter swings also drive costs indirectly: contractors spend more time managing temporary heating solutions and protecting work areas so breakers and outlets can be safely installed and tested. Jobsite access can be tighter in established neighbourhoods, especially around Pembroke Street and the older housing pockets near the downtown core, where panel locations may require additional removal and patching.
Below is a realistic comparison of common electrical services you’ll see around town, and what those projects typically cost once permits and ESA inspection requirements are included.

What affects the price of electrical work in Renfrew
In Renfrew and across the Kingston–Pembroke region, two quotes for the “same” electrical job can differ by 30–50% because older wiring conditions, service capacity, and how much wall/ceiling access is required vary widely from house to house. Ontario-wide, labour and permit workflows are consistent, but the on-the-ground complexity in older homes drives the spread: one job may be a straightforward breaker swap, while another turns into a circuit re-route and a full capacity study.
Housing age is the dominant cost driver here. Many Renfrew homes are built before 1950 and were wired for a much lower electrical load; in those cases, insurance and electrical safety expectations often push projects toward knob-and-tube removal and new circuits rather than patching. Homes from the 1960s to 1970s commonly have older panel sizes—often 60A or 100A—that can’t comfortably handle today’s load mix. Add an EV Level 2 charger and modern heat-pump systems, plus typical cooking and laundry loads, and the difference between “can we add one circuit?” and “we need an upgrade” can be several thousand dollars. That’s why a panel/service upgrade commonly falls in the $2,500–$4,500 band, while rewiring projects often start around the $6,000–$20,000 band depending on how extensive the wiring replacement is.
Aluminum wiring is another major swing factor. In homes built around 1965–1976, aluminum branch wiring remediation requires licensed work and approved CO/ALR connections; if the condition is widespread, full replacement can be the safer path. EV adoption is also driving a surge in Level 2 permit applications, and dedicated 40A versus 50A charger circuits can slightly change cable and breaker selection, which affects cost.
Concrete Renfrew examples that change your quote: (1) whether the panel is in a finished basement with limited access (usually higher), (2) whether the service conductors need upgrading for a 100A-to-200A conversion (often pushes the project toward the upper end of the $2,500–$4,500 range), and (3) whether the work is in multiple rooms with plaster/lathe or older drywall that needs meticulous patching. On the other hand, jobs priced closer to the lower end are often “single-area” work with a straightforward panel location and minimal demolition.
| Price Factor |

Extra time for calculations and documentation (smaller but real cost). |
Permits & regulations in Ontario
In Ontario, all electrical work beyond changing a light bulb must be completed by a licensed electrician. That includes anything involving wiring, adding outlets, modifying circuits, changing breakers, and—most importantly—any panel or service work. Permits are required for panel upgrades, new circuits (including EV charger circuits), rewiring, and service upgrades. Permitted work must also pass inspection by the Electrical Safety Authority (ESA). ESA is the Ontario body that oversees the notification/inspection process, and their requirements are built into most properly prepared estimates.
DIY electrical is not allowed for most homeowner electrical tasks, even if the homeowner has “basic tools.” Common activities that typically do not require an ESA permit include replacing a fixture with an identical, pre-existing connection point, or swapping a lamp/cover—so long as no wiring changes are made. But if you’re touching junction boxes, running new cable, changing receptacles, or altering panel components, plan on a licensed electrician and a permit.
Step-by-step: when hiring an electrician in Renfrew, ask for (1) their Ontario licence number and verify it using the provincial licensing registry, (2) a certificate of insurance naming you as the certificate holder if needed, and (3) confirmation of WSIB/WCB coverage where applicable. Request copies before work starts. Also ask whether ESA notification/permit pulling is included in the scope and timeline, since service changes and EV charger installations require it.
When your Renfrew home needs an electrical upgrade
In Renfrew, safety-critical electrical issues often show up differently than “cosmetic” problems. First, breakers that trip regularly—especially when using a dryer, baseboards, or kitchen appliances—can point to an overloaded panel, undersized circuits, or deteriorating connections. Treat repeated tripping as an immediate safety check, because nuisance tripping can mask loose terminations or improper load balancing.
Second, knob-and-tube wiring is a key concern. It’s not just “because it’s old.” The risk is insulation condition and connection reliability, and insurers may deny coverage or require removal. If knob-and-tube is present, plan for replacement or at minimum a properly assessed remediation program, but don’t wait for a failure.
Third, a 60A or 100A service is often inadequate in today’s load reality. Many Renfrew homes are running an EV in addition to electric heat support and modern appliances. The standard solution is frequently a 200A upgrade plus a load calculation, not simply adding the charger line.
Fourth, aluminum wiring in pre-1976 construction isn’t automatically dangerous if connections are maintained, but it does require licensed remediation with approved CO/ALR connectors or replacement where appropriate. Fifth, insufficient outlets and extension cords everywhere are a code and safety warning—especially when paired with missing AFCI/GFCI protection where required.
Why the right option matters: if you’re adding a Level 2 EV charger and your panel is already near capacity, paying for a $900–$2,400 dedicated circuit may be the “cheap” first step—but if the panel must be upgraded (commonly $2,500–$4,500), that circuit work may need to be reworked or the upgrade scheduled immediately anyway. A capacity review first can prevent paying twice.

How to choose a electrical work contractor in Renfrew
Choosing the right electrician in Renfrew is mostly about verification and clarity. Start with Ontario licensing: ask for the electrician or company licence information and confirm it through the provincial licensing registry. Next, confirm liability insurance (request a current certificate of insurance) and verify coverage for workers via WSIB/WCB documentation where applicable. If they can’t provide these items up front, that’s a red flag.
Then get 2–3 itemised written quotes. Look for a breakdown of labour hours, materials, new breakers/cable, any specialty components (like CO/ALR connectors), and—crucially—permit and ESA notification/inspection handling. Avoid lump-sum quotes that don’t say what’s included. Ask whether permit pulling is included, whether disposal/patching of small openings is included, and what the scope excludes (for example, drywall repairs beyond basic access).
Warranty matters: ask for the workmanship warranty length (how long they stand behind installation), separate from manufacturer warranties on breakers, panels, or EV chargers. Also ask whether their warranty is transferable if you sell the home.
Payment schedule: never pay more than 10–15% upfront. Hold back the remainder until the job is complete and inspected. Timeline should be in writing too—start date, expected duration, and how access/permits will affect the schedule.
- Licence number provided and verified (Ontario)
- Insurance certificate current (liability coverage)
- WSIB/WCB coverage confirmation where applicable
- Itemised quote: labour + materials, not a single lump total
- Permit/ESA notification explicitly included for service changes/new circuits
- Clear scope: what’s included vs excluded (patching, disposal, repairs)
- Load calculation mentioned for service upgrades
- Compatible parts listed (panel brand/model, breakers, AFCI/GFCI where needed)
- Workmanship warranty stated in writing
- Payment schedule with a small deposit (10–15% max)
- Start date and completion window in writing

Red flags to watch in Renfrew: (1) “No permit needed” claims for EV chargers, service changes, or new circuits, (2) pressure for a large upfront payment, (3) vague scope that doesn’t list materials or breaker/panel types, (4) unwillingness to provide insurance/WSIB/WCB confirmation, and (5) a quote that ignores older wiring conditions (like aluminum or knob-and-tube) until the job is already underway.
Frequently asked questions — electrical work in Renfrew
How much does an electrician cost in Renfrew?
In Renfrew, licensed electrician labour commonly falls in the $90–$130/hour range for journeyman work, with total cost depending on how long troubleshooting and installation takes. The overall invoice often also includes materials and ESA permit/inspection handling for major work. For homeowners, the biggest cost variable is usually the condition of older wiring and the accessibility of the panel/service location. Many pre-1981 homes require more time to safely reroute circuits, replace deteriorated connections, or document capacity before adding loads like heat pump support or an EV charger. If a quote seems unusually low, ask what’s excluded—permit handling, testing, disposal, or required upgrades.
How much does a panel upgrade cost in Renfrew?
A typical panel upgrade or service change from 100A to 200A in Renfrew is commonly in the $2,500–$4,500 range, depending on panel location, wiring condition, and the work needed at the service entrance. Because many Renfrew homes are older—76.4% of dwellings were built before 1981 (Statistics Canada, 2021 Census)—it’s common to see capacity issues when adding modern loads such as Level 2 EV charging or high-demand kitchen appliances. If the panel needs more extensive service conductor changes or panel relocation, expect to lean toward the upper end. Always confirm whether the quote includes ESA notification/permit and the load calculation documentation required for service upgrades.
Do I need to upgrade to a 200A panel?
You may need a 200A upgrade in Ontario when your current service and panel capacity can’t safely handle planned loads. It’s especially common in Renfrew when a household adds a Level 2 EV charger, electric range, hot tub, or multiple heat-support devices. The right answer depends on a load calculation and what’s already on the panel, not just the age of the house. Many older homes were built around 60A or 100A services, and today’s combinations can push the system beyond safe capacity. If your electrician reviews the panel and finds you’re near limits, upgrading to 200A is often the standard solution instead of “adding one more circuit” and risking nuisance tripping or undersized wiring runs.
How much does an EV charger installation cost in Renfrew?
For Renfrew homeowners, a Level 2 EV charger installation (typically a dedicated 40–50A circuit) is commonly in the $1,200–$2,800 range, depending on cable runs, breaker selection, and whether your panel requires upgrades. If your panel is older and doesn’t have enough capacity, you may also need a panel/service upgrade in the $2,500–$4,500 band, which changes the total project cost. ESA permits are required for the new dedicated circuit and inspection is mandatory. A good installer will confirm your circuit amperage (40A vs 50A) and run a capacity/load check so the charger installation doesn’t create problems during winter when other loads are also running.
What is knob-and-tube wiring and should I replace it?
Knob-and-tube wiring is an older wiring method found in older homes, typically from the early-to-mid 20th century. It uses porcelain knobs and tubes to route conductors and separate them from surfaces. The concern isn’t only age—it’s insulation condition and connection reliability. In practice, knob-and-tube can create safety and insurance problems, and it may not perform as intended under today’s electrical expectations and protection requirements. In Renfrew and across Ontario, if knob-and-tube is present, the usual approach is to replace affected sections with modern copper wiring and appropriate breakers/devices, often including AFCI/GFCI protection where required. The exact scope can vary—sometimes room-by-room, sometimes whole-home—based on the condition and how the home is being used.
Is aluminum wiring safe in older Renfrew homes?
Aluminum wiring can be safe when it’s in good condition and when connections are installed/remediated correctly using approved methods (commonly CO/ALR connectors) by a licensed electrician. The issue isn’t aluminum as a metal alone; it’s often the way older aluminum connections were made and how they can deteriorate over time. In older Renfrew homes (many built before 1976), aluminum branch wiring is a common scenario, so professional inspection is key. If the wiring has overheating evidence, damaged splices, or widespread connection issues, remediation or replacement is recommended. If connectors and joints have been properly addressed, the risk is reduced. For major remediation work, expect Ontario permitting and ESA inspection requirements.
