Under the BritishAlkali Act 1863, an Alkali Inspector and four subinspectors were appointed to curb discharge into the air of hydrochloricgas from the Le Blanc alkali works.
In 1874 the Inspector became the Chief Inspector. The Chief Inspector was statutorily responsible for the standards set and maintained by the Inspectorate, and reported directly to the Permanent Secretary of his Department. For the first sixty years of its existence, the Inspectorate was solely concerned with the heavy chemicals industry, but from the 1920s onwards, its responsibilities were expanded, culminating in the Alkali Order 1958. This placed all major heavy industries which emitted smoke, grit, dust and fumes under the supervision of the Inspectorate.

The Inspectorate has worked under the purview of many different departments:
A further Alkali Act was passed in 1906. Together with amendments, the Alkali Act became the main legislative control of industrial pollution in the UK. It was finally repealed and replaced by the Environmental Protection Act 1990.
