What to know before hiring a electrician in London
In Ontario, only a licensed electrical contractor (ECRA/ESA licence) may be hired for electrical work, and the contractor files a notification of work with the Electrical Safety Authority so it can be inspected. Gas appliances and fuel lines must be handled by a technician certified by the Technical Standards and Safety Authority. Plumbing and building permits come from the municipality.
Verify the licence with Electrical Safety Authority (ESA) before work starts, and ask for the permit or inspection number afterward; your home insurer may ask for it if there is ever a claim. Older London homes with aluminum branch wiring, knob-and-tube or a 60-amp service should have the whole system assessed before you add an EV charger, heat pump or hot tub.
London has a large stock of older homes in Old East and Old South alongside sprawling newer subdivisions, humid summers that keep air conditioners busy, and heavy snow from lake effect. Basement moisture and sump-pump work is common on the clay soils across the city.

Frequently asked questions
Do I need a permit for electrical work in London?
Most alterations do: new circuits, panel changes, EV chargers and anything beyond replacing a like-for-like device. Electrical Safety Authority (ESA) is the authority in Ontario; ask the electrician which permit they are filing and keep the record.
Can a handyman do electrical work in Ontario?
Only licensed electrical contractors may do electrical work for hire in Ontario, with narrow exceptions for homeowners on their own property in some provinces. Unlicensed work can void insurance and fail a resale inspection.
How do I check an electrician’s licence?
Electrical Safety Authority (ESA) publishes a public lookup for contractors it licenses. Search the business name or licence number before you pay a deposit.
Is aluminum wiring in an older London home dangerous?
Aluminum branch wiring from the 1960s and 70s is not automatically unsafe, but connections loosen over time and it needs the right connectors and periodic inspection. An electrician can assess it and quote remediation; many insurers ask about it.
