Absolutely right. I just fell into the trap and had a Worcester HE40
installed. Subsequently I found I could get spares for the old Gloworm
and as for 25% savings with a condensing boiler dream on.

That's interesting. Can you put a figure what the gas savings have been.

It depends on what you started with and the weather.

I replaced a 65% SEDBUK efficient piece of GlowWorm crap with a 90%
efficient condensing boiler and the savings average 25-28% for periods
of time of equivalent outside temperature.

This was done by making weekly gas meter readings and continuously
logged outside temperature readings and the results are quite
consistent.
