Not sure if I was being stupid, but had to do trial and error in the bottom left corner

So did I !!! The rest of the puzzle was relatively easy.

I gave up. I'm sure there must be some trick to doing kakuros that I don't know. I always struggle with them

There might be a better way, but here's what I did...
Let's assume you've got this far: https://imgur.com/I1YSVWk. Look at the two blanks squares in the "25" column. * They obviously can't be 3 or 8. * They can't be 9 because the 16 and 23 to the right both need a 9 somewhere (this is kind of a "mini X-Wing"). * They can't be 1, 2 or 4 because then the 1st, 2nd, 3rd and 6th squares would sum to 10, leaving 19 or 20 for the remaining two squares which is too large. * In the 29 row, the blank square can't be 7 because that would force the 3rd, 4th and 5th squares to sum to 24, leaving only 5 for the remaining three squares, which is too small!
That leaves 5 or 6 for the first square and 5, 6 or 7 for the second. If the second was 5 or 6, that would force these two squares to sum to 11, meaning the square above (in the 7 row) would need to be 3 which isn't allowed. Therefore the second square must be 7. The rest is then easy!
(Edit: Updated the image after missing some obvious numbers in the RH corner.)

Just wanted to say what an excellent explanation of that bottom-left corner you have posted! Thanks!

Thank you Pseudo, that helped a lot. I think it was the "mini X-wing" that had me stumped. I completed the puzzle in almost a third of my original time. (Still nowhere near as quick as you though!)

Just the sort of discussion I enjoy and hope for, thank you everyone, especially Pseudo. I often find Kakuro far from easy for some reason and this helps.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
