As above, catalytic converter is dead. Reasons for this can be collapsed monolith or poor spark from degraded ignition coils causing excess fuel to enter the cat. Or both 
Change the cat, and the ignition coils and plugs if they've not been replaced in the last 12 months. You don't want to go to the expense of changing the cat for it to become fudged again immediately from poor spark.

Can it be compression tested before spending anymore money on it?
You don't want to go down the path of replacing the cat and coils and then find out that the rotor tips are that worn that there's hardly any compression.
I was admiring one recently. The chap said that he'd bought it for what the vendor had spent fixing it.

What these guys have said, the cat has collapsed, likely through the effect of some dying ignition components.Change the cat, and the ignition coils and plugs if they've not been replaced in the last 12 months.

.I had this exact problem with my car. The CAT is dead and needs replaced. It is most likely one or more of the fuel injectors have failed and are basicaly pssing petrol through the engine.
DO NOT DRIVE the car get it trailered or towed to the garage. and tell them to check the fuel system . At least one will be knackered (you would be as well to replace them all) and you will need a new cat.
You will need to budget £1000-£1500 to fix everything.
I also had a bearing in my gearbox fail a month after this which I think was caused by the extreme heat from the burning cat which is close to the gearbox.
