# Bulk licence checks and API — qbcc

> Check a list of subcontractors against the QBCC register, watch them for change, or query it programmatically.

## Bulk checks, watching and API

The pages here are free. What is not free is doing this for four hundred subcontractors, class by class, every quarter.

### Who does this at volume

- **Head contractors and builders.** Engaging an unlicensed
subcontractor, or one licensed for the wrong class, is a problem that surfaces
at the worst moment. The check has to be per class, not per name.
- **Insurers and lenders.** 13,546 licences sit in a graded
financial category rather than self-certification — that is the register's own
signal about the size of the business behind the licence.
- **Councils, property managers and platforms** that list or
engage trades, and have to show they checked.

The trap is the same for all three: **38.8% of licences
carry more than one class**, so “is this person licensed?”
has no useful answer. The question is always “licensed *for
what*?”

### What we can do on your list

- **Resolve a list.** Send licence numbers, names or ABNs; get
back a CSV with every class of work the licence covers, the grade, the
financial category, the postcode, and the ABN where we hold one (we hold it
for 52.8% of licences).
- **Watch your subcontractors.** Give us your list; we compare
each collection with the last and tell you what moved — a class added, a
licence gone from the register.
- **Query it.** A JSON endpoint by licence number, to put the
check inside your own onboarding.

Priced case by case: resolving 400 numbers once is not watching 4,000 every
month. Say what you need and we answer with a figure and a sample against your
own data.

### Tell us what you need to check

Describe the list or the watch. We reply with a sample run against your own data, and a price. No payment is taken on this site.

Every request is answered by hand. Your details are used to reply and nothing else — see the [privacy page](/privacy.md).

Want the register as a dataset instead? [The prepared datasets, with prices](/data.md).
