What to check before you hire

Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
In 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.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
