Buzzing consumer unit

I have recently fitted some dimmable low energy bulbs and changed the dimmer switch (link below) which I was advised was designed to be used with low energy dimmable bulbs

However, when I now have the lights on (dimmed or on full power) I get a buzzing on the breaker at the consumer unit.

Does anyone know why I get this buzzing and how I can stop it

thanks

How many bulbs are operated by the switch and what wattage are they?

the circuit is a 2 way with only one dimmer switch

thanks

It's normal for the dimmer switch to be buzzing but not the on the MCB.

I wouldn't use a dimmer on low energy lighting. Fit a normal switch and see if the buzzing stops.
