How are you applying the fertiliser and how often , and what sort of soil do you have ? And what brand of fertiliser is that ? I've not seen any with a potassium feed higher than nitrogen for Spring / summer fertiliser . I assume the autumn feed is the same as the winter feed if not you should be using the winter feed from September onwards .
Not much you can do if its on the highest setting just keep on top of it, I scarify my lawn twice a year around about now and early spring March.
Scarify early Spring ( March weather pending ) when the grass is starting to grow 8'C + . If you have a garden fork you can fork the lawn going down at least 10cm or just do the worst areas ( where most moss forms or where its walked on most ) , 250m2 is a lot of lawn to fork . Over seed the entire lawn and top dress if budget allows , I use just top soil cause I am a cheap sake and because top dress is way over priced .
If you had done it earlier like mid September I would of re attack the lawn to make more of a seed bed / aerated and get the new seed down , the lawn has 6 month of recover time and time for the new grass to establish for spring , that would be renovating the lawn . It may be a tad late now for such a task but they is always spring . Lawns can be a chore at times and a lot of hard work .
Sorry it wasn’t clear but I listed the fertilisers separately - spring/summer, autumn, winter.
I have learnt a lot - thanks to all for your help!
You've accidently copied and paste the autumn feed twice that's why I were questioning it . I do have that earthway spreader myself, its to big for my own lawn unfortunately so I use a different one now .
I agree let nature take its course and revaluate the lawn in spring. Keep an eye on the grass seed it may get washed around before it germinates .
If you're somewhere that tends to have mild autumns, reseeding the bald/thin areas now might be worth a try but don't leave it any later. It would be borderline here.

And I agree, aerating by hand with a fork is bloomin' hard work. I only regularly do the bits that get most compacted - under the washing line and the route to the compost bin - and I do it in short bursts usually in the spring/early summer.

I seeded the bare patches and overseeded the rest and then covered with lawn topdressing. Used Autumn fertiliser and a few weeks on with plenty of rain and warm temps.....

there is no way I am aerating by hand, so will wait until spring and share the cost of a hire machine with a neighbour.
I live in west central Scotland - not where that photo is...

Still a way to go, but looking a lot better!
