Power that comes on by itself
An automatic standby generator with a transfer switch brings your London home or business back online within seconds of an outage, no extension cords, no refueling a portable in the dark. All Service London sizes, installs, and services them.
London and Middlesex weather takes the power out often enough that a standby generator is a practical investment, especially for a home with a heat pump, a business that cannot afford the downtime, or anyone running medical equipment. We size the unit to the loads that matter, install the transfer switch, and wire the connection to code.
An automatic standby setup senses the outage, starts itself, transfers the load, and shuts back down when the grid returns. Add a standby generator to a panel and service upgrade and the whole job is done by one crew.
