An overflowing drain that takes water from the roof gutters.
The grate is not moveable but there is a drain access metal cover about a metre from it.
I don't have the poles to poke about in there though.
If you really don't fancy buying a set of rods or poking about Dynorod usually get it done for around £100.
I've seen more complicated jobs (especially internal blocked pipes) cost £3-400 and people have paid upwards of £150 just to witness someone unblock an exterior drain in seconds with a rod.
