Subfloor Ventilation on the Central Coast

What subfloor ventilation on the Central Coast actually involves

Check the contractor on the NSW Government's online licence check before signing. The licence is needed above A$5,000 for the building work, and for all specialist work, electrical wiring included, whatever it costs. Do not pay any money without a written contract: the builder or tradesperson must give you one for a job over A$5,000, a more extensive large job contract applies over A$20,000, and a deposit must not exceed 10% of the contract price.

After the electrical work

The electrician who tests the work must lodge a Certificate of Compliance for Electrical Work no later than 7 days after the test. Give the electrician your email address so a copy is sent to you once it is lodged.

What the job does not need

A passive vent replacement or a cleaning job under A$5,000, with no wiring involved, needs no licence at all: the Act excludes non-specialist work below the amount the regulation sets. Whether a particular job crosses that line is the first thing a written quote should answer. For a job over A$20,000 the builder must also have home building compensation cover, and the contract must carry a cooling-off period of five clear business days.

Which licence category covers fixed ventilation work above A$5,000 is not settled by any government page read for this site, and neither is whether installing the fan unit itself counts as separate mechanical services work, which would apply at any value. Ask the provider, and ask Building Commission NSW in writing if the answer matters to you. The costs page lists every rule against the job's value, and the suburbs page lists the areas this site covers.

Subfloor Ventilation on the Central Coast — common questions

Does my subfloor ventilation job need a licence?

It depends what is involved. Installing, altering or repairing a fixed ventilation fixture is residential building work, and over A$5,000 in labour and materials the contractor needs a NSW contractor licence. Any electrical wiring needs a licensed electrician at any value. A passive vent or cleaning job under A$5,000 with no wiring needs no licence at all.

How do I check a contractor?

Use the NSW Government's online tool to check a contractor or tradesperson is qualified and licensed for the job. A licence is needed for residential building work valued above A$5,000 in labour and materials, including GST, and for all specialist work whatever it costs.

Do I get a written contract?

For a job over A$5,000 including GST the builder or tradesperson must give you a written contract. Do not pay any money without one. A deposit must not exceed 10% of the contract price.
