The Vaillant and the Worcester are similar qulaity and similar priced units.
This is a combi to combi exchange - TRVs may need to be fitted, the system needs to be flushed out and the new boiler should be a condensing unit.
I would think the £1350 is about right but you might not get all the right paperwork for that. The Biasi would possibly be a non-condensing unit and thus technically illegal.
The £2350 is more like a BG style quote.
IME a straight swap is half a day's work. My local fitter charges £350 labour so he's still making money hand over fist. Shop around
