“We accepted a quote to repaint our house. The painter now wants to increase the price. Can he do this?”

In short, no. A quote is an exact price for a job and it’s binding on both parties once accepted. If you’ve already agreed to the price, the painter can’t spring an increase on you.
The painter has to wear the cost if the job takes longer than expected or requires extra materials: they can’t ask you to pay the difference just because they’ve got the sums wrong.
The law doesn’t just cover tradies. It also applies to quotes from lawyers or any other service provider. When you agree to a quote, you’ve formed a contract and both parties have to meet their obligations under the contract.
It’s a different situation if you’ve been given an estimate for a job. Unlike quotes, estimates are approximate prices. When you agree to work on the basis of an estimate, what you pay may be different, but not wildly. You should be able to rely on the tradie to give you a figure close to the true cost of the work.
Always ask to be contacted if problems crop up during a job that could affect the cost. In our opinion, it’s worth challenging a bill that’s more than 20% above an estimate.
You’ve also got grounds to challenge a bill if you’ve agreed for work to go ahead without being given any price and the amount you’re charged is excessive. Where no cost is agreed beforehand, the Consumer Guarantees Act says the price you’re billed has to be reasonable.
For example, you can rely on the act if you need to get a plumber to do urgent repairs on your property, but then get stung with a huge bill for the work done. The best way of challenging the bill is to get estimates for the same work from several plumbers, then offer to pay your plumber the average.
