What to know

Gas work is not optional

Anyone who works on gas appliances in Cardiff must be on the Gas Safe Register. Ask to see the card. Oil boilers and unvented cylinders have their own competence schemes — ask which one applies.

Quotes and call-outs

Ask what the call-out covers, whether evenings cost more, and whether diagnosis is free if you proceed.
