I drained my feeder tank in my loft yesterday to adjust the ball cock
but after re filling I have no water to my cold water taps. I guess
that debris has blocked the pipes if so how can I remove this and could
it be an air lock?

Its much more likely to be an air lock. Try putting a flexiblepipe over the
bathroom cold tap if possible and with the cold tap open try blowing back
with your mouth over the end of the flexible hose. This often clears the
problem, but shows a problem with the layout of the pipework which makes
this lekly to happen.
