Inside the Mahawewa workshop
Engineers who've built for Australia — now building from Sri Lanka
Since 2021, BWS Engineering has delivered high-quality switchboard solutions tailored to each client's requirements, with a relentless focus on precision, safety and durability. We started with one aim: to bring Australian standards and Sri Lankan craftsmanship together, so contractors get compliant boards at a better cost.
Our sister company E3 Power Solutions designs and installs solar and battery systems across Sri Lanka — many of them protected by BWS-built boards.
