L3 YR1 Unit 306 session 4 Regulations and manufacturers ins

​Unit 306
Understand relevant industry standards and regulations 
British Standards and approved codes of practice 

​British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. 

 These provide guidance on interpreting and following regulations. 

​The British Standards are not enforceable, but they set out a series of recommendations so that the minimum standard to comply with the regulations can be achieved. 

 By adhering to the recommendations within the British Standards, the regulations will be seen to be satisfied.

When was the BSI formed? 

​However important the regulations and the British Standards are, they are not our primary source of information when installing equipment and appliances. 

 Manufacturers’ guidance overrides both of these. 

​Manufacturers’ guidance 

​Manufacturers’ installation, servicing/maintenance and user instructions are the most important documents you will have access to when installing, servicing and maintaining equipment and appliances. 

​ They tell us in basic installation language what we must do for correct and safe operation of their equipment. 

 This guidance must be followed, otherwise:
  

● the terms of the warranty will be void  

● the installation may be dangerous  

● we may inadvertently be breaking the regulations. 

​ In some instances, it may seem that the instructions contradict the regulations or the British Standards.

This is because regulations are reviewed only periodically, whereas manufacturers are moving forward all the time with new, more efficient products, so their information may be more up to date.


In these cases, follow a simple but effective rule: the manufacturers’ guidance must be followed at all times.
