It appears that your office is located in Karnataka State. As I don't have much information regarding Karnataka's S & E, I am unable to give you a proper suggestion. Therefore, I would suggest you go through the S & E Act and Rules applicable in your state in detail.
Amendment Process in West Bengal
However, as per the S & E Act and Rules applicable in West Bengal, an amendment of the S & E Certificate is required due to a change in the office address. Following this change, one must obtain a new trade license from the relevant authorities. Subsequently, the amendment of the Registration Certificate can be processed. You are required to submit the original certificate along with Form-C (indicating the change of address), the trade license, and payment of the necessary fees to the Registering authorities under the Shop & Establishment Act. Upon satisfaction with the application for amendment, the concerned Inspector will amend the certificate and send it back to you.
