If you need to change your electrical meter in Mumbai, you can contact your local electricity distribution company or utility provider. In Mumbai, the electricity distribution is managed by BEST (Brihanmumbai Electric Supply and Transport Undertaking) and Tata Power. You can contact their customer care centers or visit their websites for more information on how to get your meter changed.
Typically, changing an electrical meter requires a qualified electrician to disconnect the old meter and install the new one. You may need to provide some documents such as your latest electricity bill and proof of identity/address to complete the process. The cost of meter replacement may vary depending on the type of meter and your electricity consumption.
It is important to ensure that the new meter is properly installed and calibrated to avoid any inaccuracies in measuring your electricity consumption. You can also consider requesting for a calibration certificate from the electrician after the installation.
