Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Verify at the sourceCheck them yourself
Electrical work in Ireland must be carried out and certified by a Registered Electrical Contractor on the statutory Safe Electric register. Checking they're listed is free and takes a minute - do it before you hire.
Check the Safe Electric registerIn Ireland, gas work must by law be done by a Registered Gas Installer (RGI) and electrical work by a contractor registered with Safe Electric. Verify the registration on the public register before any gas or electrical job, as using an unregistered installer is illegal and dangerous.
Agree an itemised written quote with staged payments tied to completed work rather than a large cash deposit up front, and confirm the tradesperson's public-liability insurance before they start.
Look for consistent reviews across several named sources, not one polished profile.
