Sounds like you have too high of water pressure entering the home. Any plumber has a gauge that can test the pressure. If it’s over 60 psi or so, you should consider installing a pressure regulator. Once your pressure is moderated, the thumping should go away.

Dont worry, theres nothing wrong.
its only making a noise because of the water pressure varying as you turn on the tap. Try bleeding the radiators if its bugging you

Air in the pipes is a common cause
