Your boiler has a sedbuk rating of 78% so in a few words "not a lot"
Modern boilers, 90% in condensing mode.

If you kept your boiler mostly condensing then you could save about 12% plus about 4-6% because the heat exchanger is more efficient on most condensing boilers.
BUT keeping the settings so that its condensing well usually means using weather compensation control and by NOT fiddling with it. Also having somehat over sized radiators.

Unless you have a very old floor mounting boiler with a conventional flue it will never pay to replace a boiler unless your gas bill is over £1500pa.
Not yours, but those old boilers are very reliable and have very low repair costs.
Yours is reasonable efficient! But they do break down quite often so you may get your chance reasonably soon.
