Gas (Exempt Supplies) Act 1993
The Gas (Exempt Supplies) Act 1993 (1993 c. 1) is an Act of the Parliament of the United Kingdom which amended the prohibition on certain unauthorised gas supplies and amended the duties of the Director General of Gas Supply. Background 
The Gas Act 1986, which had privatised the British gas industry, had been focussed on large suppliers of gas. The associated bureaucracy and regulation costs were an impediment to smaller suppliers. These included suppliers of LPG (liquified petroleum gas, comprising butane and propane). The Gas (Exempt Supplies) Bill had started as a Private Members Bill in the House of Lords and was intended to remove the prohibition on unauthorised supply of gas from smaller operators. Gas (Exempt Supplies) Act 1993 
The Gas (Exempt Supplies) Act 1993 received royal assent on 19 January 1993. Its long title is ‘An Act to amend section 5 of the Gas Act 1986; and for connected purposes.’
