Banging/loose service cover

There is a cover in the road banging every time a car drives over it. It is extremely loud and is waking the family in the night. This has been an ongoing issue for at least the last year but only when heavier vehicles passed over it. Now it is much louder and can be as frequent as every one to two seconds when timed. There is obviously a safety issue here too for road users including cyclists and pedestrians if a car was to lose control as it becomes increasingly more unstable. Hopefully someone can review this with a matter of urgency thanks
