Just had a massive downpour and seems the inner tube of the vertical flue lets water in .

The boiler is not connected as the plumber is doing that next week but I have put the flue through the roof hence noticing it .

It's a condensing flue for oil system.
It is new and water is only coming from the middle and no where else.

I didn't know if this is normal .

This is normal also your dectite isn’t sealed / correctly installed eg your flashing

Also your flue looks a bit close to the roof
 
The photo was taken before sealent and waterproof screws wasput on.

Regarding distance what is official measurement , plumber dint mentioned it when I said where I would put it.

Cheers

What’s the manufacturer of the oil boiler ?
 
Needs to be 750mm from the pitched roof I would say
 
Assuming that's the end of flue so could make it a lot higher .

Not really as it needs to drop as the white isn’t rated for external
 
Flue termination requirements will be found in the manual for the boiler, alternatively in the OFTEC books. They vary depending on certain scenarios.
As Simon says though you really should leave this to the installer. Safe discharge of POC is not to be compromised.
 
I wouldn't use a dectite flashing on a flat roof your better off with a spun aluminium flashing there's gonna be alot of water splashing about on a heavy down pour . Kop

Warmflow do their own flat roof flashing available through any of the main plumbers merchants just be careful it meets the manufacturers instructions ? when the boiler is installed , I use CT1 sealant to fix and seal the flashing . Best of luck . Kop
