Qualified and experienced in heritage electrical systems


Sydney’s specialist electricians in heritage-listed building works

Our considerations for heritage building works extend beyond safety, legality, and functionality alone. At TN Electrical, we understand just how critical it is to preserve the unique historical character of these structures.

With heritage buildings originally designed to accommodate limited services, our expertise allows us to carefully integrate present-day electrical systems into spaces for which they were never intended, while also respecting the historic character of each structure.

Heritage-listed electrical repairs

Deteriorated wiring, faulty connections… we’ll identify the fault and develop a solution that doesn’t compromise the authentic, historical charm of the building.

Heritage system rewiring

Using existing voids, holes, notches and cable runs to conceal electrical components, combined with quality components for longevity, we can upgrade your heritage building to meet present-day energy demands while also maintaining its historical integrity.

Heritage-listed system upgrades/installations

Power issues? We’ll replace damaged wiring with modern alternatives to ensure your building’s electrical system is code-compliant and reliable, while also preserving its original heritage features.

Safety upgrades for heritage buildings

Whether installing additional outlets, upgrading circuit breakers, or implementing solutions for surge protection, our safety solutions always respect the historical integrity of your building.

Heritage-compliant electrical works

At TN Electrical, we ensure electrical works meet all relevant historical and Australian building code regulations and requirements.


BMA House

BMA house was originally constructed in the 1930’s and is a beautiful 12 storey heritage listed building.

The works required replacement of the entire electrical distribution system from the incoming supply through to 60x tenancy sub boards, whilst being fully occupied by medical and legal practitioners.

Complexities were vast including retaining the heritage features of the building, ensuring power outages where kept to a minimum, extremely limited storage on site, noise / dust minimisation, confined working areas, limited access, after hours work to name a few.

This job was completed early to the delight of the client.



“The Rockfort” being a 1928 constructed heritage listed residential apartment building consisting of 21 individual units that where fully occupied presented a massive challenge for our team to perform an entire rewire of the electrical installation.

From the installation of new service mains, main switch board, metering, unit sub boards, and re wiring of all final sub circuits, we have totally upgraded this building to meet all current code requirements. Being as the project was performed “Design and Construct in house” we have been able to “Value Add” by incorporating in our design elements such as the installation of Gate Metering, Solar and Battery Array Systems that will provide energy cost savings into the future.

This showcases our ability to create innovative solutions to upgrade an original installation to today’s standards whilst preserving the buildings heritage architecture.


Quality-focused and compliant electrical works for heritage and culturally-important building projects

The additional challenges presented by heritage and buildings of cultural significance requires not only electrical expertise, but also a willingness to invest significant time and effort to ensure an optimum outcome.

TN Electrical does this with an understanding of, and a commitment to protect, the essential historical and/or cultural characteristics of each building.

From intensive research to close collaboration with local councils, community groups, heritage professionals and other government agencies, our process delivers a quality outcome every time.
