The vast majority of tradespeople are honest, skilled professionals who take pride in their work. But rogue traders do exist — and they tend to follow recognisable patterns. Knowing what to look for can protect you from a very expensive mistake.

They approach you unsolicited

Legitimate tradespeople don't usually knock on doors offering to fix things you didn't know were broken. If someone approaches you out of the blue — especially claiming to have 'noticed a problem' with your roof, driveway or guttering — be very cautious.

They pressure you to decide immediately

High-pressure sales tactics — 'this price is only available today', 'I have materials left over from a nearby job' — are classic warning signs. A professional tradesperson will give you time to consider a quote and won't mind you getting other opinions.

They ask for a large cash deposit upfront

A reasonable deposit for materials is normal on larger jobs. But asking for 50% or more in cash before any work starts is a red flag. Pay by bank transfer or card where possible — it gives you a paper trail and more options if something goes wrong.

They can't provide insurance or qualifications

Any legitimate tradesperson should be able to show you proof of public liability insurance and, for regulated trades, their relevant certification. If they're evasive, say they'll 'send it later', or get defensive when asked, walk away.
