See Regulation 7
Under the byelaws 1986, fines levied were £400 in respect of each offence with a further fine of £40 per day after conviction (if the breach was not rectified).
However, under the 1999 Regulations things are quite different.
The 1999 Regulations states that a person who contravenes the regulations may on conviction be subject to a fine not exceeding level 3 on the standard scale. Presently (1999) level 3 means a fine of up to £1000* for each offence.
*Because of the nature of the Regulations this usually results in multiples of Regulations broken, hence this means multiples of £1000.
