thanks softus
not sure on the make and model of the pump but i have had a look over it and cant see anything that may look like a bleed screw.
the pipework to it is from the hot water cylinder and from the cold water header tank
the pipework then goes from my pump to feed my mixer shower
on another note, i believe i may have caused the airlock by some plumbing i did in the bathroom and had to drain both hot and cold systems down, and also the hot water taps to the bath and bathroom sink operate at a much reduced pressure than previous

Which is airlocked - hot or cold?
If hot, then do you have a bath filler? If so, then put your hand over the filler, open the hot tap, then the cold, and let the cold backfill the hot supply; close hot first, then cold, then remove hand.
Then start the shower on fullest hot setting.
If this doesn't work then switch off the pump and repeat the above trick with your finger over the shower hose (with the spray head removed).
If all that doesn't work, then remove an outlet from the shower pump and wait for water to gush out. Obviously it helps if you have valves on the inlets so that you can control the gush, but cover the pump and electrics with towels before you start and don't worry about a bit of water splashing around, as long as it's not a torrent.

with regards to the mixer shower, i have taken the shower head off and when i open the mixer nothig comes out
i have a mixer tap on my bath and sink and both these are fed by gravity fed supplies, hot and cold.
i suspect an airlock somewhere on the pump inlet side.
would a solution be to use my washing machine hoses connected across hot and cold pipes downstairs, to try and force cold mains water through my hot water system to try a free the air lock?

i will try your suggestions, but your last suggestion of removing one of the outlet hoses from the pump sounds a bit tricky because i have looked at the hoses going into and out of the pump and these look as though they may have some kind of bayonet fitting?
i forgot to mention that the inlet hoses both have gate valves connected to them and i had closed these and open these several times during my plumbing alterations, could one of these be sticking?
thanks

I know what you mean, but it's probably a pushfit connection of the John Guest variety. If there are any valves on the outlet then you could uncouple from one of these (after shutting off on the inlet), and control the flow of water using the inlet valve.nabby68 said:
Possibly - how many turns did it take to open each gate valve?
there are no valves on the outlet side
how hard or easy is it to undo the pushfit connection?
and it took abt 3 or four turns to re-open the gate valves on the inlet side
the reason i suggested trying to force mains water through the hot water side was bacause after i had finished all the plumbing work, the shower and pump initially worked ok but the hot water to the basin and the bath in particular were flowing at a very slow rate, but i found a leaky joint and had to shut off everything again, when i opened everything up again, thats when the problem with the shower ocurred
thanks again for your help
