On top of that, he's a lovely bloke!"
"Our central heating broke and I was really anxious, I rang Llandaff Heating and Plumbing and Christian came out straight away. He is lovely! He was polite, kind and very reliable. I won't use anyone else for our heating and plumbing needs now."

As someone who is clueless with boilers, plumbing etc he clearly talked through the issue, resolved it with no extra or hidden costs."
