filler or something similar and then paint it?

Once rot has got a hold anything like this is just a stopgap. The only way
is to cut it out and replace with new timber. Which won't cost 'lots of
fivers'.

No. that i actually not true.

If u can get the wood dry, and then apply a very runny resin to it that
soaks into the rotten fibres and stabilises (and seals against more
water ingress) then making good with another resin is fine: the issue is
a balance between when new wood and the labour to fit it is cheaper than
the filler.
