Yes it’s possible, but under certain conditions. The rate applied to the second meter will depend on the use that you make of the garage. For instance, if it is not used as a residential unit, your consumption will be billed at the general rate for business customers (Rate G).
In any case, you would first have to discuss your project with a master electrician. You should know that the work done by the electrician will be at your expense. Your master electrician will contact us so that we may carry out the necessary work and install a meter, if applicable. Fees will be charged to you based on the work that is done.
