Just a couple of quick questions, am I allowed to work on a condensate pipe or do you have to be an RGI?

I have just got a condensing tumble drier and want to plumb the water outlet into a drain, the tumble drier is sited under the boiler as can be seen in the picture. What I want to do it 'tap' into the drain that services the condensate pipe on the left, can I trim the black flexible pipe back so I extend the white plastic drain pipe to a some sort of Y piece so I can connect the boiler and the tumble drier to the drain?

cheers for any thoughts.

Yes that's fine although the easiest way would be to cut into the white drainage pipe about 4" below the top of the dryer then use a tee to go sideways and an elbow to point it back up to take the dryer hose.

Cheers, the simplest ways are the best, don't know why I didn't think of that.

How would I know what size pipe it is? is it likely to be 21.5mm over flow pipe, its pushed into 22mm clips and then runs about 1.5 metres and joins with a larger grey soil pipe from the sink with a reducing T.

It'll have the size printed on it, and probably stamped into the fittings as well

I've just checked and there no markings at all on the pipe or the fittings, they're just glued together. I take it you cant get 22mm plastic pipe (designed for water) with glued fittings? if so I can assume its 21.5mm overflow.
 
Has a trap been considered in this modification to prevent smells from escaping the drainage system, or am I missing something?

Didn’t think I’d need one as the condensate outlet pipe I’d be cutting into would already have the trap in the boiler and the other side where the smaller pipe t’s into the sink soil pipe is at the exterior wall and the pipe only protudes about 6 inch through to the outside wall where it’s discharged into an open grid so I assume and smell would exit here rather than travel a few metres back up the condensate pipe.

Then it's been "considered", which was not detailed in your OP. (y)
