Hi all,

We are looking at purchasing a house that has a suite and is still on 100amp electric.

What would our cost be (roughly) to upgrade? House is 2280sq ft in total (240 of that is unfinished)

The house is in Colwood, BC (near Victoria)

Hello Nicki,

Do you have certain valid reasons for requiring 200 amp upgrade? The size of your home would not require one that large unless you plan on a second kitchen, hot tub, electric heating, etc. Most homes here in Ontario range from $1600-

$3000 for that upgrade.

There is already a second kitchen and we want to add a private laundry for the suite so that there is no shared space.

We have been told the electric system is maxed out already so the extra laundry would require the upgrade.

Any licensed electrical contractor should be able to tell you what your home would require if you wish to call a few in and get some quotes. Max'ed out may not actually calculate as maximum when a qualified electrician does some math for you. We are trained to do this accurately and inform you on what is really required. But ultimately, if you want the upgrade (providing local hydro can supply it to your address), the pricing previously noted would be an idea for you depending on where you live and surrounding environment.

The cost will depend if the meter is behind the electric panel, it will be $1800.00/\.

Hi Nikki,

Colwood is a beautiful area... have some friends that live in the area...

I am curious as to the requirement as Robert. If you were going to upgrade I would be considering separating the suite from the main electrical panel and putting on a separate meter.

If it is just an issue of availability of spaces for breakers, then a panel change vice an entire upgrade to 200 amps might be considered.

As Robert indicated that there is a calculation that can be completed to determine what size your service needs to be. In general most experienced Electrical Contractors can accurately determine what the requirements will be without the calculation. Standard sizes of 100, 200 and 400 are the most cost effective for residential applications.

As for cost - there are too many variables to give any reasonable estimate; it could be $1500, it could be $5000. Call in at least three Licensed Electrical Contractors (LEC) and let them determine what your budget should be. Make sure to check their credentials and all are carrying the proper paperwork for permits, insurance, etc.
