We've just moved house and this is the cooker hood in the kitchen. 
I've never had one of these before so I'm not entirely sure how they work, but shouldn't it be venting somewhere???
The only thing at the top is the top of the cupboards. The hood sucks air when you switch it on but surely it has nowhere to go? 🤔🤨🫤

Is there a boiler in that RH wall cupboard? Is that wall an external one? Could you try standing on a chair and looking at the tops of these cupboards - any flat ducting?

Looks like a flask on top of the cupboard to me!

I really must stop using the forum on my phone :-)

no boiler, wall is internal. there's just a hole on top of the cupboard 😀

In which case, it's in 'recirculating' mode, which - as you surmise - significantly compromises performance.
It doesn't get rid of steam, and relies on carbon filters to remove odour.
I'm surprised the ceiling above that outlet isn't stained. 
I don't suppose you have an external wall to the right? If so, you could run flat, rectangular ducting sling the wall tops, and have a vent hole cut through t'wall.

The exterior wall is to the left. I just presumed it was all vented out there then I noticed there was no vent on the wall outside 😂

You could vent it through that outside wall, just don't go through the lintel holding up the wall above the window!

Again, I must stop replying to these threads on my bludy phone - I thought that was an open doorway into another room on the left, and not a window as I now see.

I've also corrected my previous reply - a recirculating hood does not remove 'steam'.

As EExile says, you could run a duct leftward along above the wall units, and exit through that wall - avoiding the lintel.

😂 thankyou everyone for your replies 😀

You're welcome.

Worth getting a quote or two - external venting is far superior to recirculating.

Happy New Year.

And using smooth bore ducting rather than flexible hosing makes for a much more efficient system. If you go for 225x25mm or 204x60mm rectangular ducting, Manrose do a wall vent (almost) the same size as a standard brick. If installed with care, you'd hardly notice it.

Used 204x60mm ducting in my kitchen, and put the vent through a fascia board (flat roof over part of the kitchen). Unless you know where to look, the vent is almost invisible

Ceiling looks clean above the cooker hood. I have a recirculating Philips one that vents out the top like the OP's. 
No problems with moisture, grease on ceiling or lingering odours from cooking and the filters are easy to change.
If it's doing the job OK, just keep as is.

Before you decide whether to spend any money on adding an external vent it might be a good idea to give it a clean and maybe replace the filter in case that's all it needs. I wouldn't be surprised if things slipped a bit when the previous owners were packing up all their bits and bobs.
There's a guide from Good Housekeeping here.
