    Gary got back to me fast, was professional, transparent about what needed to be done and costs were completely reasonable. The team that did the work were clean, explained everything and turned up precisely when they said they were going to. Mercury will get all my electrical work from now on.

    Fuse box tripped and this was linked to the water tank, leaving me with no electricity.

    Posted 13 October 2025

    They were very efficient. I was left with no electricity on Sunday afternoon and they attended my property first thing Monday morning. They explained what the problem in a way I could understand and dealt with it really efficiently. They were really professional and affordable. Can't fault them.
