On the estates you can use a toilet flusher blank from b&q. Cost a couple of quid and only come in white but a bit of spray paint and its whatever colour you choose. They have the advantage of an o ring and threaded so theres no way your going to push it through like a grommit. Wont work on the hatch as the hole on the estate is much bigger.
