How much does it cost to upgrade from 100 amp to 200 amp service?
The cost to upgrade from 100 amp to 200 amp service varies by home and is confirmed after an on-site inspection. If a panel upgrade is needed, our page notes it typically adds $1,500 to $4,000 to the project. Total service upgrade costs depend on existing service layout and code-compliance work; our licensed, in-house electricians have resolved complex configurations, including unusual service setups. We serve Weston and surrounding Massachusetts cities.
