Need to replace central heating system and finish off double glazing but we
can't afford to do both, so which should be the priority?

Have you insulated the house, the loft and walls in particular?
Either will keep the heat in better than double glazing.

Most of the house was DG'd about 10 years ago except for (for various
reasons) 3 windows. These have got - at best - about 4 years life left in
them, but they are draughty and when the wind blows in a certain direction,
the curtains move quite considerably.

Draughtproofing strips are readily available and so is secondary
glazing. These can reduce draughts a lot for a few years.

We also have a 10-year old Baxi Bermuda 552 back boiler (rest of the
pipework and rads that make up the CH system are 33 years old - original
install when the house was built) that is kettling badly - so much so that
we have to turn up the telly volume to get over it.

Having insulated the walls and loft I would look at a new boiler and
converting the heating system to a more modern form. This would
probably be replacing the cylinder, providing a separate header tank
for the heating system and installing modern controls. Whether I
would replace the existing pipework and radiators would depend on
their condition.
