Records created and used by the British and Irish Magnetic Telegraph Company

The collection comprises of secretariat records, financial records and examples of telegraphs.

The British and Irish Magnetic Telegraph Company was the closest rival to the Electric Telegraph Company. It was formed in 1857 through the merger of the English and Irish Magnetic Telegraph Company and British Electric Telegraph Company, with its headquarters being based in Liverpool. It operated wires along the railway lines which had not been secured by the ETC, mainly in the north of England, Scotland and Ireland. In contrast to the other telegraph companies, many of its lines were underground.

The company was included in the Acts of Parliament which brought the telegraph system under the control of the Post Office, being paid £1,244,000.

This collection has been arranged by business function.
