I've got a small drip from the back of the pump housing on my Baxi 105e - you can just see it in the picture.

Looking at the parts list it seems there's an o-ring seal(#86) between the back of the plastic housing and the small metal flange that carries the return pipe assembly (#70). I think it's coming from here and it only happens when cold.
This morning I was able to nip-up the upper of the two plated screws on the pump housing by about an eighth of a turn so it may have helped.

However, just in case it hasn't......
Is this a DIY job or should I call in a plumber?
If it's a DIY job, how should I go about it - anything scary to watch out for?
Many thanks!

Isolate electrics, close flow and return valves, these are good and do not leak. Drain via drain valve under to the right of pump. Undo 2 screws, pull pump away enough to access the o rings, water will be still about so cover electrics/pcb, clean area, replace with new. Then reverse. Easy for a DIYer, this boiler when filled will vent itself for a while so be patient, open the auto air vent if it's shut on top of pump.
