If you get that then does it matter if the trenches get filled in?

You will have the trenches redug before the bco visits again.

 

As long as the existing footings are as deep as your new ones, you don't have to worry.

Have you considered getting friends or family to have a concrete party. One mixing at the front, barrow round, level off.   A few hours and it is done.

Just a quick update as not much has happened.  Still waiting for confirmation of "commencement" from BCO. 

Have just paid diggerman - £560  which I think is reasonable for 2 trial holes, one 8 m trench 1.2 m deep, and exposing massive roots of conifer.  Two visits in all.

Grinder coming to deal with conifer stump on 30 June so will post photos.
