Service change vs. service upgrade — what's the difference?

These two phrases come up on almost every panel job, and people use them like they mean the same thing. They don’t, quite. The difference is small on the day the work happens, but it changes the paperwork, sometimes the cost, and occasionally what BC Hydro needs from you. Here’s the plain version.

The short answer

A service upgrade makes your electrical service bigger. The usual one is going from a 100-amp service to 200 amps so the house can carry more, a heat pump, an EV charger, an induction range, a suite, or all of the above.

A service change replaces the equipment at the same size. The panel, the meter base, or the service mast comes out and new gear goes in, but the amperage stays where it was. You’d do this because the existing equipment is old, damaged, or a brand with a known defect history, not because you need more capacity.

So: upgrade means more power, change means new gear at the same power. That’s the whole distinction.

Why the day looks almost identical

Here’s why the terms blur together. Whether we’re upgrading you to 200 amps or changing out a tired 100-amp panel for a new 100-amp one, the physical job is nearly the same. BC Hydro pulls the meter and disconnects in the morning, we swap the panel and service equipment, an inspector signs off, and power comes back the same afternoon in most cases. From your kitchen window it looks like one job.

The difference lives in the details. An upgrade needs a load calculation to prove the new, larger service is sized right, and heavier conductors and a bigger meter base to match. A straight change reuses the existing service size, so the math is simpler. Both are permitted and inspected either way.

When you need which

You need a service upgrade when the house is running out of room. The signs are familiar: breakers tripping when two big appliances run together, a panel with no spare slots, or a plan to add something heavy like a heat pump or a Level 2 charger. If you’re weighing whether a charger actually forces an upgrade, that often comes down to a load calculation rather than a guess, and we walk through it on the panel and service upgrades page.

You need a service change when the capacity is fine but the equipment isn’t. The most common case is an aging panel or a hazard brand like Federal Pacific or Zinsco that an insurer has flagged. The 100-amp service might be plenty for how you live, but the box it runs through is due. Swapping it for modern, inspected gear removes the hazard without touching the service size.

Plenty of jobs end up being both. If we’re opening up the service anyway and the house is close to needing more capacity, it’s often worth doing the upgrade in the same visit rather than paying for the disruption twice.

Does it change the cost?

Somewhat. An upgrade generally costs a bit more than a same-size change because of the heavier conductors, the larger meter base, and sometimes a new mast, plus the load calculation. But the biggest cost drivers are the same for both: whether your service is overhead or underground, whether the panel has to move to meet clearance rules, and what the wall between the meter and panel is made of. We break the real price drivers down in what a panel upgrade actually costs in BC.

The honest way to think about it: the label matters less to your wallet than the site conditions. A straightforward 200-amp upgrade on an easy service can cost less than a same-size change on a house where the panel has to relocate.

Why the wording still matters

If the terms are nearly interchangeable on the day, why bother sorting them out? Two reasons.

First, permits and BC Hydro. A change in service size occasionally changes what BC Hydro needs on their end, and the permit reflects which job you’re actually doing. Getting the description right keeps the paperwork clean.

Second, it keeps you from buying the wrong thing. “Service change” is the term BC Hydro and permit offices tend to use, so people sometimes ask for one when what they need is an upgrade, or the reverse. A quote that says “service change” when you’re actually adding a heat pump and an EV charger is a quote for the wrong job. We’ll tell you which one your situation calls for before anything is booked, rather than defaulting to the bigger number.

The bottom line

Upgrade means more amps. Change means new equipment at the same amps. Most homeowners come to us needing one or the other and don’t know which, which is fine, that’s our job to work out. If you’re in North Vancouver or anywhere on our route, the North Vancouver panel and service upgrade page covers the local specifics, and you can always just ask for a quote and we’ll sort out which job you actually need.
