How to find a trustworthy electrician in Mexico City

Electrical problems are the home repair issue expats in Mexico City feel most nervous about — and for good reason. Bad electrical work is a fire risk, and finding someone competent without local references is genuinely difficult. Here's what to look for.

The most common electrical problems in CDMX apartments

• Tripped circuit breakers that keep tripping: Usually overloaded circuits in older buildings not designed for modern appliances (air conditioners, washing machines, etc.).
• Outlets that don't work: Often a tripped GFCI (interruptor de falla a tierra) elsewhere in the apartment — check bathrooms and kitchen first.
• Lights flickering: Can indicate a loose connection or a problem with the building's incoming supply.
• No ground wire: Extremely common in buildings pre-dating the 1980s. Important if you're using sensitive electronics or appliances.

Green and red flags when hiring

A trustworthy electrician will always give you a quote before starting work, explain what they found and what needs to be done, and be honest about what falls outside their scope. Red flags include refusing to give a written quote, starting work before agreeing a price, or claiming everything needs to be replaced when a repair would do.

A note on permits and certification in Mexico

Residential electrical work in Mexico City does not require a permit for most repairs and installations. However, for new electrical panels, major rewiring or commercial work, using a certified professional is strongly advisable. For standard apartment repairs, an experienced and recommended electrician is sufficient. See our electrical service →
