I would say this is, actually, a cheese plant. The number and size of the holes in the leaves increase with age.

Thanks to Ojibway93 for your reply. When looking up Cheeseplant, they always seem to be climbing yet my plant doesnt want to climb at all.

An old one I used to have did a bit of climbing up a moss pole which I Kept damp and pushed the aerial roots into.

I had a cheeseplant years ago and I had to physically tie it to a moss post to keep it upright. Apparently in their native environment, they grow along the ground, hence the aerial roots hanging down, but when we put them in a pot we try to grow them upright. I had mine for many years but it never flowers, I dunno if they're supposed to.

I think that it's one of the Philodendrum species.
Here is a photo of one in bloom..................

I think it's a Monstera deliciosa, or Swiss Cheese Plant - it's more of a creeper than a climber.

We had one at work many years ago which grew fruits like rough green bananas, but I don't remember seeing it with flowers.

It's a Philodendron selloum, which we know of as Tree Philodendron, or (confusingly) Split-Leaf Philodendron. Eventually, they can develop a trunk to 4 feet tall, but that can take decades, indoors.

Thanks to all that have commented. On further investigation as a result, I agree with "Tugbrethil" that it is indeed a Philodendron selloum. I didnt go for the Cheese Plant idea as the ends of the leaf lobes are round unlike the flat cheese plant leaves.
The trunk is very much like what I have on a much smaller scale in the pot.
It has been happy yet small in the pot, should I put it in a much larger container and let it develop?
