I have loads of the 1/4 turn in-line 15mm isolators that I was going
to fit to all the taps etc as i'm re-plumbing the bathroom, however
looking at one they seem to narrow from the 15mm of the pipe to 10mm
or so where the ball valve is.

So would it be a bad idea to fit these to the bath taps since they may
slow down the filling of a bath? I have a gravity fed HW system but am
looking in 1 or 2 years to upgrade to a combi-boiler which I believe
runs off mains pressure.

Buy full bore valves like these or it's 22mm equivalent for the bath

although having said that I have these as well and they work fine but
where I stay there is loads of water gushing through the pipes .

They'll slow down a 15mm low pressure feed too - best to use full bore
ones of the correct size for the pipe.

Many would call that a downgrade.

The reduced bore may well slow down the filling of the bath - but that
will be a good thing as it will prepare your the family for the even
slower filling you will get when you do your combi downgrade.

Are they really that bad? I rarely use the bath neither does my
girlfriend so would this be a good choice for CH / showers, wahsing up
and to save money since my boiler is 10-20yr old I guess the
efficiency is around 60% and a new one upto 95%?

RE the taps I also had bought 15mm flexi connectors that go to the
bath tap size fitting and used that as well as the isolators - flow
from the tap seems adequate but certainly not fast - the water's not
gushing out though don't know how long it would take to fill the bath?
The supply pipe is only 15mm as well which I guess may not be ideal...
