I've just moved into a house which has a wooden floor and a Baxi
Bermuda back boiler/fire.

A vent in the floor exists already but it's on the opposite side of the
room and will be covered up by the sofa.

When I got a guy in to service the back boiler, he said he recommended
installing a vent directly in front of the fire as the one currently
installed is effectively useless.

So, is it as simple as rolling back the carpet, chopping a square out
of the floorboards and the carpet and then screwing some fancy looking
brass plate over the top?

Or is there more to it?

You'll need to find out how big it has to be -- do you have the
boiler's installation instructions? You will probably find it needs
to be much bigger than you imagined. Also, it mustn't be closable,
because someone might close it! You would also need to make sure
there is plenty of under-floor ventilation to the outside -- I think
there are some rules for this case but I don't know them off-hand.
