Mini piling - do I need to issue section 6

[Wadrian]

Hi 

 

could really do with some feedback on this. I am doing mini piling on my self build which is due to start next Wednesday! Just read that I need to issue a section 6 notice to my neighbour. The house is 4m from neighbour and I am using 150mm pile using grundomat method. It is a detached house and next door is a detached house which is 4m from my new build. 
 

my piler says I am fine and can just do the work. Any had experience of this?
