The tradesperson is late or hasn't arrived. What should I do?

First, check the agreed start time and give the tradesperson 30 minutes — London traffic catches a lot of people out. After that, send a message through Get Trady messaging asking for an ETA. If they're more than 2 hours late with no reply: photograph the empty job site (your phone will timestamp it), keep messaging through Get Trady, and note what's happening. If they're more than 24 hours late and still haven't replied or arrived, that's a no-show — and you're entitled to raise a formal dispute from your booking dashboard.
