Note: Fines under the 1847 Act (First Scheme), 1907 Act and the 1925 Act are set at Level 1. The offences under the 1925 Act also have a maximum daily rate of £1. In London the offences attract a fine at Level 2. These are not fixed penalty notice provisions and so enforcement would be through the Magistrates’ Court.
