A 200-amp panel upgrade in London involves replacing your electrical service entrance, installing a new main breaker panel, utility coordination (your local utility requires a temporary disconnect), and a city electrical inspection before the utility reconnects service. Plan for 1–2 days of work plus 2–6 weeks for utility scheduling.
A licensed electrician handles all panel work. The permit process in London typically adds $200–$500 to the project cost but is non-negotiable — unpermitted panel work creates serious insurance and resale liability.
A straightforward 200-amp upgrade in London costs $1,500–$5,500 in most markets, $2,000–$7,000 in high-cost metros like LA and NYC. Homes that also need a meter socket upgrade or service entrance cable replacement add $500–$1,500.

How Panel Upgrade Works in London
What to expect from a licensed London electrician from first call to completion.
- 1
Load Calculation
The electrician calculates your home's total load to confirm the right amperage (100A, 200A, or 400A) and identify any circuits that need to be reconfigured.
- 2
Permit Application
A permit is required for all panel work. The electrician submits the permit and schedules both a utility disconnect and a city inspection.
- 3
Panel Replacement
Utility disconnects the service. The old panel is removed, the new service entrance and main breaker are installed, and all circuits are reconnected and labeled.
- 4
Surge Protection & Grounding
A whole-home surge protective device (SPD) is installed as required by NEC 2020. Grounding and bonding are verified and updated.
- 5
Inspection & Sign-Off
The city inspector verifies the installation. Utility reconnects service after the inspection passes. Final load test confirms all circuits are functional.
