Fire doors must be installed by a competent person—someone with the appropriate training, experience, and skills. Poorly fitted fire doors, regardless of their rating, may fail in as little as five minutes during a fire.
								 
				
									There are strict requirements outlined in building regulations that govern fire door installation. For example, the gap between the door and the frame should be between 2mm and 4mm—something that requires precision and expertise to achieve. These standards are difficult to meet without proper joinery skills and experience.
								 
				
									While the Code of Practice for Fire Door Assemblies does not mandate specific certification for installers, the Regulatory Reform (Fire Safety) Order 2005 states that fire doors must be installed by someone competent. This means a person who has adequate knowledge, training, and qualifications in fire door installation.
Hiring a professional fire door installer offers peace of mind to the Responsible Person or property owner, ensuring that the fire door will perform correctly in the event of a fire.
