“We had just moved in to our new home and the electrics were all over the place.

Praetorius Electrical Services walked us through our options, so we could customise the house to our liking.

They replaced our lights, sockets, and fuseboard. Praetorius provided a highly professional service and I would thoroughly recommend speaking to Billy before you start work in your home.”

“I highly recommend Praetorius Electrical Services Ltd to everyone.

Although the work was already done, whenever I have a question or i require any advice, he is always there for us and gives prompt replies.

He is not just very professional but also a very freindly person. Billy has explained everything about the whole processand also supplied great customer service after the work.
