It ****ed down here a bit today and generally seems a lot better and no leaking but still a bit of overflow (much less) making it wet under the pergola.
For whatever reason they pitched the pergola to fall back into the house guttering so it just isn't enough down pipes considering it was extended in the first place, it just can't cope with the extra square metres.
The only way I can think of sorting it out with the existing structure is to use battens to slope it away from the house or to drop the posts and beams but either way surely would need another gutter on the pergola.
Hopefully I won't get more leaking inside as that is most important but still need to sort out this pergola because it is not ideal :(

Upsize your dwelling downpipes to 100x75, I’ll put quids on them being 100x50.
Identify your stormwater plumbing and (yes, sigh) re-pitch the awning to fall the other way, tie your new plumbing in. Good solid DIY project.
