These two terms get used interchangeably and they shouldn't. A panel upgrade replaces the box. A service upgrade increases how much electricity your house can pull from BC Hydro. They overlap, but they're not the same job, and they have different price points and timelines.
This guide explains the difference, when you need each, and when both make sense at once.
The simplest distinction
| Panel upgrade | Service upgrade |
|---|---|
| Replaces the panel itself (the box on the wall) | Increases the amperage your home can pull from BC Hydro |
| Same total amperage (usually 100A in, 100A out) | Doubles or triples the amperage (often 100A → 200A) |
| No BC Hydro coordination required | BC Hydro must disconnect/reconnect |
| 1 day, power off 4 to 8 hours | 1 day, power off 4 to 6 hours, full process 2 to 3 weeks |
| $2,200 to $4,500 typical | $3,800 to $5,500 typical |
| Permit: $90 to $140 | Permit: $90 to $140, BC Hydro coordination |
In plain English: a panel upgrade is just a new box. A service upgrade is more electricity coming into the house.
When you need a panel upgrade only
Three common scenarios where a like-for-like panel replacement is the right move:
- You have a Federal Pioneer Stab-Lok or Zinsco panel flagged by your insurance. Replace the panel, keep the same 100A service. Fixes the safety issue without involving BC Hydro. Cost: $2,200 to $3,800.
- Your panel is full (no spare slots) but your service amperage is fine. We replace with a larger panel that has more circuit slots. Often combined with adding new circuits for an EV charger or heat pump.
- The panel is corroded or damaged but the service capacity is adequate. Common in Langley homes that had a basement flood or mouse damage to the panel.
In all three cases, BC Hydro doesn't need to come out. The work is internal. The total power coming into your home is unchanged.
When you need a service upgrade only
This is rarer but happens:
- You have a 200A-rated panel with a 100A main breaker. Some Langley homes built in the 2000s had panels installed that were oversized for the original service. Upgrading the service is just swapping the meter base, conductors, and main breaker. The panel stays.
- Your panel is in good shape but your total load needs more headroom. You're adding heat pump + electric range + EV charger and the load calculation shows you'll exceed 100A. The panel works fine; the incoming service is what needs upgrading.
These are uncommon. Usually if a service upgrade is needed, the panel also benefits from being upgraded at the same time.
When you need both
This is the typical Langley scenario for major load additions:
- You're adding multiple electric appliances (heat pump + EV charger + electric range) and your 100A service is already at 70%+ capacity per the load calculation.
- Your panel is older (Federal Pioneer, Zinsco, fuse panel, or just 30+ years old) and you're adding load. Doing both jobs together saves $500 to $900 vs splitting them.
- You're doing a major renovation or addition and the existing 100A service can't handle the new total load.
When both are needed, bundling saves money and BC Hydro coordination time. One permit, one disconnect, one inspection.
The decision tree
Use this to figure out which job applies to you:
Step 1: Is your panel a Federal Pioneer, Zinsco, or fuse panel?
- Yes → Panel upgrade required. Read Federal Pioneer Panel Replacement: Why It Matters.
- No → Continue.
Step 2: Is your panel full (no spare slots) AND you need to add a new circuit?
- Yes → Panel upgrade. May or may not need service upgrade depending on Step 3.
- No → Continue.
Step 3: Are you adding major electric load (heat pump, EV charger, electric range, hot tub) on top of existing electric loads?
- Yes → Run the load calculation. If over 80A continuous on a 100A service, service upgrade.
- No → Probably no upgrade needed. Just the new circuit.
Step 4: Is your panel showing physical signs of failure (warm, buzzing, burning smell, won't reset)?
- Yes → Panel upgrade urgent. See Signs You Need a Panel Upgrade.
- No → Continue.
Step 5: Is your home older than 40 years AND you're planning major electrical work in the next 5 years?
- Yes → Worth bundling a service upgrade with the work. Future-proofs the home.
- No → Stick with what you have.
Cost difference
Standalone panel upgrade: $2,200 to $4,500 Standalone service upgrade: $3,800 to $5,500 Bundled: $4,500 to $7,500
Notice that bundled is less than the sum of the two standalone costs. That's because:
- One permit instead of two
- One BC Hydro coordination
- One disconnect/reconnect
- Materials shared across both jobs (we replace the panel and the conductors in one trip)
If you're going to need both within the next 2 to 3 years, just bundle now.
Timeline difference
| Job | Time from quote to done |
|---|---|
| Panel upgrade | 5 to 10 business days |
| Service upgrade | 2 to 3 weeks |
| Bundled | 2 to 3 weeks (same as service upgrade alone) |
The BC Hydro coordination is the long pole on the service upgrade. Panel-only jobs don't touch BC Hydro and move faster.
How to know which you actually need
Send us photos:
- The open panel showing breakers
- The label inside the panel door
- The exterior meter base
- List of all major electric loads in the home (heat pump, water heater, range, dryer, EV charger, hot tub)
We'll run the BC Electrical Code Section 8 load calculation and tell you within 24 hours whether you need a panel upgrade, a service upgrade, both, or neither.

Frequently asked
- Sometimes. If your existing panel is rated for 200A but currently has a 100A main breaker, yes — we just swap the main breaker, the meter base, and the service entrance. If your panel is rated for 100A or less, no, you'll need both.
- Yes. Like-for-like panel replacement is common — same amperage, same location, just newer panel. This is what insurance-driven Federal Pioneer replacements usually look like.
- A service upgrade is more expensive than a panel-only upgrade because it involves BC Hydro coordination, meter base work, and service entrance conductor changes. Standalone service upgrades run $3,800 to $5,500 in Langley vs $2,200 to $4,500 for a like-for-like panel replacement.
- Often you'll need neither. Many 100A homes can support a Level 2 EV charger with no upgrade. The need for a panel or service upgrade depends on your existing total load — heat pump, electric range, electric water heater, and other major loads stack up.
- A panel upgrade. If you have a Federal Pioneer or Zinsco panel that needs replacement for safety/insurance reasons, that's a panel upgrade — the panel itself is replaced. A service upgrade doesn't address panel safety; it just increases incoming amperage.
