When the barometric air pressure is low would this cause the sealed pressure gauge on a central heating system to fall,checked and found no leaks,thanks in advance for any answers.

If it was going to affect it at all it would cause it to rise. The pressure inside the sealed system relative to the atmospheric pressure outside would increase. however, such a difference would be minimal. For a start the difference between "High" and "Low" atmospheric pressure in the UK is no more than about 70 millibars (compared to about 2 bar in the sealed system). But as well as that, the effect of any changes in atmospheric pressure on a system sealed inside largely rigid vessels and pipes would be absolutely miniscule. 

I'm assuming this is a 'combi' system, frip?

As M'lud has said, it's miniscule, and anyway, that's why the pressure vessel is there: to 'soak up' any variations in pressure.
