Cromer is a central Northern Beaches suburb with a strong family demographic, where 1960s to 70s homes on generous blocks often need modern electrical upgrades. The original estate wiring gave each house four to six circuits on a ceramic fuse board, which is why switchboard replacements, granny flat sub-boards and extra kitchen and home-office circuits make up most of the electrical quotes owners here are comparing.
Every install, switchboard upgrade and repair is performed by our team of NSW-licensed electrician partners under Quotcha's coordination.

Local context
Cromer (NSW 2099) has factors that materially affect electrical installation and repair pricing.
Cromer was developed as a family housing estate in the 1960s to 70s. Most homes have original switchboards with ceramic fuses and limited circuit numbers that cannot support modern loads. A board upgrade quote for a Cromer home should include splitting the old shared power circuits, adding dedicated circuits for the kitchen and air conditioning, and RCD protection on every circuit.
Large blocks in Cromer are popular for granny flat additions. These require separate sub-boards, metering considerations, and dedicated circuits run from the main supply. The sub-main across the backyard is usually underground in conduit, and the quote should show trench length, cable size and whether the main board has the capacity and a spare way for the new sub-main.
Proximity to Cromer schools drives renovation activity. Kitchen and bathroom electrical upgrades, additional lighting circuits, and data cabling are commonly quoted work. A modern kitchen alone can add three or four circuits for the oven, induction cooktop, dishwasher and bench outlets, so the quote should list each new circuit rather than pricing the kitchen as one item.
Cromer's relatively flat terrain makes underground cable runs and trenching straightforward, potentially reducing labour costs compared to hillside suburbs. That should be visible in the quote: a granny flat feed or garden lighting run on a flat Cromer block should not carry the access and excavation premiums that a steep Beacon Hill or Bilgola block would.

FAQs
Yes. A granny flat or secondary dwelling requires a dedicated sub-board with its own RCD protection, and may need separate metering depending on whether it's a complying development or DA-approved dwelling. If a separate meter is wanted, the Ausgrid application and meter installation are extra steps outside the electrician's own work, and the quote should identify those costs as pass-through.
A typical 3 to 4 bedroom home should have 8 to 12 circuits minimum: separate circuits for lighting, GPOs, kitchen appliances, hot water, air conditioning, and any high-draw items. Many 1960s Cromer homes have only 4 to 6 circuits. Extra circuits mean extra cable runs from the board, so a quote that lists each circuit and where it goes is easier to compare than a headline price.
In most cases, yes. The board can be replaced and RCD protection added while the existing TPS wiring stays, as long as it tests within insulation resistance limits. The electrician should test each circuit before connecting it to the new board, and the quote should say what happens if a circuit fails, since a failed lighting circuit in a 1960s home is not unusual.
A standard switchboard upgrade typically costs $1,500–$3,500 on the Northern Beaches. Add $300–$600 for asbestos backing board removal, more for three-phase upgrades or Ausgrid notification/metering changes.
