Sounds ok then, we’ve had a baxi for 6 years but I seem to recall Worcester recommended a max rise of 1 bar when hot. The boiler we have now has a bigger expansion vessel so has more scope to absorb any pressure increase I guess. If it’s going above the safety relief pressure and venting out then you should look a bit deeper but sounds like yours is probably ok, worth a read of manual to see what it says though

And they haven't managed to do it properly either.
Pointless and poorly done.
Whilst a drain tap would be easier, could you not disconnect the boiler fill loop, boiler side and open the tap??

Just because I’m curious and clueless, what did they do wrong?
I suppose you could, but you’d have to get spanners out and that might be beyond the average homeowner?
On the filling loop, should both these taps be closed?

fill loop has one way flow thats why they have arrows on them
its far easier to just to fit a drain tap or as i call it a fast drain tap compared to the rubbish drain off valve type
just remember if it takes hours to drain and fill a system then your paying more if the plumber used a drain tap he can drain the system in a short time do whats needed and refil the system in less hrs
mostly fitted on rads from downflowing pipes

id rather use a proper stop tap tee'ed off from the main pipe but allows for faster drain off of the central heating system compared to the one above
