Cold house?Describe the fault. We’ll find the part.
Skip the category tree. Tell our parts assistant the appliance, the fault code or the GC number — it works back to the exact component and confirms fitment before you pay.

The parts assistant
It knows the catalogue. You don’t have to.
Trained on the full 110,000-component catalogue, fitment data and every appliance we’ve supplied. It narrows down the part — a person still signs it off.
Diagnose from a fault code
Give it the code and the appliance. It returns the likely causes in order of probability, with the parts for each.
Search by GC number
Paste the Gas Council number and it identifies the appliance, then lists every spare we hold for it.
Confirm fitment before you pay
Anything the assistant is unsure of goes to the technical team. You get a human answer, not a guess.

Our customers
Don’t just take our word for it
“Spoke to a lady at Hanicks on Monday morning to source me a Baxi burner. She later phoned me to say she had found one, ordered that day and arrived Wednesday morning. Very polite lady and excellent service.”
