Plumbing issue

Can anyone help me with this issue

When I turn my wah hand basin tap off in the bathroom, I get a glug, glug glug noise coming from underneath it, but if I flush the toilet at the same time as turning the tap off, the basin pipes do not make a noise?

would you care to elaborate

Last year we had a new bathroom suite fitted and it is just recently that the wash hand basin pipes are making a noise when the tap is turned off and the water runs away. When the toilet is flushed just after the bathroom tap is turned off there is no unusual noise. Any suggestions why or a cure?

Something is clogging up. Try cleaning the trap under the basin.

could also be you need to fit an anti vac trap to the basin
