Membership of MOSL is open to companies that have the appropriate licences to operate as wholesalers or retailers in the new competitive non-household market.
Applications for membership may be made at any time and there is no limit on the number of members provided they hold the appropriate operating license.
Under its current constitution, MOSL offers two types of membership:
Membership as a Licenced Undertaker is open to organisations that hold appointments under the Water Industry Act 1991 and to new area variations (NAVs) or to their associated companies.
Membership as a New Entrant is open to organisations that hold water or sewerage supply licences under the Water Industry Act 1991 and to companies holding licences granted under the Water Services etc. (Scotland) Act 2005. If a company meeting either of these criteria is associated with a company that is, or qualifies as, a licensed undertaker it is currently unable to become a member of MOSL in its own right.
Further information is provided in the MOSL Articles of Association.
