Hi I live in a purpose built block of 15 flats built in 1974, over 4 strories, will the doors still cover the current regulations ,as they were built to regulations made in 1974

 

 

All depends some will, some won't, all the doors should be assessed and those that fail the assessment should be upgraded or replaced. The common areas are subject to a fire risk assessment under The Regulatory Reform (Fire Safety) Order 2005 and any fire doors that do not meet the required standard will be considered a significant finding and should appear in the FRA.

This is the benchmark guidance for flats - as you will see there is some leeway for smaller older blocks:
