Simply looking at a fuse board like the one pictured below, old fuse carriers with wire fuses can be seen.
The cost to upgrade to a more modern and serviceable basic 9 pole enclosure within the old box, using circuit breakers, including labour is over $1,500.
The cost of fitting a new box with a basic 9 pole enclosure, including circuit breakers would be over $3,000.
Most houses will require double this allowance of circuit breakers for a family home.
This is before any additional wiring work is required, for the house to be able to supply all the modern requirements that you will need.
It's important to realise the risks associated with old wiring, old fuses and overloading issues due to modern living requirements can cause fires.
To rewire an old home, or even to relocate the power board may cost you between $3,000 to $7,000.
Another consideration is safety switches, often existing ones are not adequate for any additional wiring and further costs may be required, that an electrician will need to assess.
A simple call out fee for an electrician to inspect your issues or minor works ranges from $75 to $150, then they charge approximately $70 to $120 per hour for work performed.
A building and pest inspection will not advise you of the costs required to upgrade a fuse box and board, but having photos of the fuse board and advising of issues is often included.
