Hi

i admit i know 0 when it comes to plumbing but learning bags from this
group.

when we flush the loo the plumbing seems to make a lot of noise (not the
water while refilling but near the end of the refill).

Juddering? Water hammer, whatever. Probably easiest to start with the ball 
valve. Is it old and caked up? Clean it. Simply adjusting the float will 
often alter the water flow dynamics enough to stop the juddering. Check that 
you have the correct insert for high or low pressure (mains or tank feed). 
Or replace the valve with a 'silent' valve perhaps, cost about about 6. If 
fiddling with that doesn't stop the noise, check your pipe runs. If the feed 
is from the loft tank make sure any long 'horizontal' runs actually have a 
fall away from the tank in order to prevent small pockets of air - not big 
enough to prevent flow but enough to cause noise. Are the pipes particularly 
old? Consider replacing them. If mains fed and particularly high pressure - 
consider fitting a flow limiter. Are the pipes suitably clipped? Loose pipes 
can contribute to noise. And are they suitable lagged?

Echo all of this, or perhaps experiment with closing the servicing valve
slightly to reduce the flow.  a tad easier than most of the other
alternatives,  finacially & risk free and easy to try.
