Also there is a kitchen sink & a washing machine just below the boiler why on earth did they just not drill a 22mm hole in the back of your work top and simply connect the condensate to your internal waste from the sink or Washing machine is beyond me.

Apologies , I have not read all the posts but as Darren suggests this is so simple its untrue .

Would have saved lots of hassle
I have actually used these when I was on the books. the local council used to order them for the boiler swaps. They are ok but in my opinion. I prefer 21.5mm rigid pipe inside. Less to go wrong
 
I haven't seen such a poor installation before.
You need to get them back to finish the job. The water from the condense is acidic and lead flashing does not like acid. No wonder you neighbour is not happy.
Did they fill in the benchmark in your boiler book.
Was the person who installed this GSR.
They obviously didn't know the basics.
How can it be signed off?

Agree wouldn't use one even if I had no other choice

They are perfect for getting round the back of kitchen cupboards. Always best to hrd pipe where you can but the flex will get you out of a tight spot

I fine they block more easily due to the ribs and they dip very easily as there's no strength to them

Had to replace a load of them for the local council
 
Nice bit of bonding wouldn't go amiss either, looks like pants if I'm honest.

may i ask why, the case is metal, so if the pipes are bonded at source eg water and gas no need to bond at boiler
