What to know before buying
Listing details to confirm
Check the 35mm size and square shape against your existing firebed and appliance requirements. Position replacement coals only as directed by the appliance manufacturer, keeping burners, ports and pilot areas unblocked. The listing describes the coals for compatible gas, LPG and certain decorative displays, while another description says most standard gas and electric fires. Compatibility is therefore not confirmed for every appliance.

Aggregate ratings lean positive, with many five-star ratings, but the distribution also includes lower ratings. This offers only a broad indication of customer sentiment and does not identify specific strengths or problems. For a replacement-coal purchase, checking the stated size, shape and appliance layout is more directly useful than the overall rating.
