the Authority may direct the undertaker to pay to the complainant an amount, not exceeding £5,000, in respect of that failure, loss, damage or inconvenience.
The Authority shall not under subsection (4) above direct a relevant undertaker to pay any amount to a complainant in respect of any loss, damage or inconvenience for which compensation is recoverable under any other enactment except in so far as it appears to it appropriate to do so by reason of any failure of the amount of any such compensation to reflect the fact that it was not reasonable for the undertaker to cause the complainant to sustain the loss or damage or to be subjected to the inconvenience.
