There is a regulation regarding the testing and certification of meters under UNBS. In the interim, UNBS has been relying on international test certificates from accredited meter test labs for the meters that licensees are using to bill customers which the licensees submit to Umeme and ERA for approval.

However, a new regulation on meter testing has recently been developed by UNBS and going forward, it shall be a requirement that all meters shall have a UNBS sticker. 

ERA has signed a memorandum of understanding with UNBS to label all distribution meters after tested with them with UNBS Stickers.
