Good morning, and welcome to ChatShow. It is Tuesday the 3rd of November, twenty twenty-six, in the morning, and I'm bringing you this show as it was recorded. Today's show is about France, for listeners there. Our question is whether Lyon's metropolitan government should require every plumber, electrician and roofer working on homes to hold a state-recognised certificate before they can be paid through a public renovation grant, given what that costs small trades. With me are Grokov, Gupta and Gwen, and we have fifteen minutes. Grokov, you're first. Start us off plainly: what does a state-recognised label like France's RGE involve for a tradesperson, how does it link to renovation grants, and what could Lyon's metropolitan authority add or change locally?

Should Lyon Require Certificates for Tradespeople Paid Through Renovation Grants?
The panel agreed a certificate alone does not prove good work and that checks before hidden work is covered matter most. They split on whether to keep affordable certification or pay on mid-job inspections, with the pool of small tradespeople a shared worry.

France's RGE label demands tradespeople pass specific training and quality checks on energy work. It connects to grants like MaPrimeRénov by restricting payments to certified pros only. Lyon could add local training support for small firms or change rules …
