Hi I am getting deaf (old age) and can no longer hear my ding dong door
bell when I am in the kitchen. I bought a cheap wireless door chime
from Lidl but it is not much use. When someone comes to the door it
makes my wireless internet drop out, also it now needs a new battery
and it costs more than I paid for the door chime.

They also tend to be not very loud.

In my kitchen cupboard just under the consumer unit is the bell
transformer, installed when the house was built so all the wiring is
cunningly hidden.

Right.

So I thought, is it possible to connect a second bell to the transformer
so that the old ding dong bell just inside the door and a new bell in
the kitchen will both ring at the same time? If when someone is
pressing the bell push at the front door and cannot hear a bell ring
they think the bell is broken and batter on the door so I want the ding
dong bell at the front door to ding dong as well. I think that is why
the battery on the wireless one does not last long because it could not
be heard at the front door.

I'd change the ding dong for an underdome bell. They are the loudest of
these sort of things.

And I worked out that the transformer's electricity usage is less than
the cost of batteries and I can get a doorbell from a friend for
nothing before they find out that their new wireless door bell will
cost them more in batteries :-)

So if it is possible how would I wire it up? Would I just disconnect one
wire from the transformer and connect it to the bell and connect a wire
from the bell to the transformer?

Yes - that will wire them in series. But depending on type one may not
work properly as it depends on how much current each takes. They really
need to be the same.

I have two of these which can be heard throughout the largish house.

Hmm. I wonder if that is meaty enough. Mine is 1 amp.
