What does this statement mean? A waived connection cannot retrospectively be assigned to a property after it has gone live?

If a shareholder buys 1500 shares in a block then they can claim a waived connection fee which is worth £60. This can be for their house, or they can nominate someone else’s house, – however, this must be applied for before the property gets a live connection.  For example, they can’t be connected for a month, then buy the shares and retrospectively ask for the cost of their connection to be refunded.
