About CJ Doyle | Accredited Infrastructure Contractor Sydney

CJ Doyle Contracting Services has been a trusted name in utility and civil infrastructure since 1980. Founded and led by Christopher Doyle, the business began in sewer and water construction, establishing a reputation for reliability, quality workmanship, and consistent delivery across Sydney’s growing development sector.

In 1993, the electrical division was introduced, expanding the company’s capabilities and strengthening its position in the market. Today, CJ Doyle is recognised as a leading Accredited Service Provider (ASP), delivering electrical, sewer, and water infrastructure for residential subdivisions, industrial developments, and major projects across NSW.

Our strength lies in experienced teams, well-maintained plant and equipment, and a disciplined approach to project delivery.
