Yes if its in the vent part. If its in the wet part - no.

Thanks for that rosebery, samr job another question. Can I put an air admittance vale on the end instead of going aruond the eaves, mainlr because the only way I could get to the eaves is to put up scafolding, the soil pipe is external.

Hi thanks for that, can I put an air admittance valve on the top instead of going around the eaves?

You can only use an AAV on a soil vent if there is at least one other vent on your system that is venting to the outside air. If this is the only stack you have got then no you may not use an AAV.
