Some guttering advice required
Options

Hi, during heavy rainfall water pours through the drainpipe/guttering, that exits onto our kitchen roof, gets collected by another level of guttering and through a down pipe into the drain.
But the rainflow is faster than what the guttering and pipes can cope with so water is flowing over the side of the roof and all over the place.
And it's worse when windy.

How can I change my current set up to stop this issue.?
Can I add piping to connect to the existing guttering so none of splashes over the roof etc?

I know nothing about the terminology involved so could be using the wrong words to describe everything!
Hopefully the photos explains it better.
Many thanks

Well, whithout knowing the whole picture of your 'current setup', I can suggest extending the downpipe over the roof of the extension, then down around the guttering, then connecting it to the lower downpipe. This is assuming that the lower downpipe isn't blocked and can cope with the total flow.1

This is assuming that the lower downpipe isn't blocked and can cope with the total flow.Depending on the pitch & distance of the roof, the extended downpipe may need some brackets to stop it flapping around. Looks like a felt or epdm roof (unusual for a ptched roof).A spreader to extend the area over which the upper downpipe discharges on to the lower roof might help. But that does depend on the lower guttering & downpipe being able to cope with the extra flow.Is it possible to fit a new downpipe at the boundary with next door ?The slope of the guttering would need to be changed, but that would mean that you are not discharging over the extension roof. You'd also need to dig down for more underground drainage, so a lot more work.

And really the edpm should have had a dam end on the slope
Is the blue protective plastic still on the fascia.
If that fascia drip/edge is too long so the water fires over the gutter you could maybe space it out a bit. This can happen with edpm as the water accelerates well down it.0 -
Do not know if it is my screen/ eyesight but does that stack appear to have movement six courses up from neighbours flashing.0

The top section is 3.5 bricks wide, and the bottom section 3.75 bricks, so the bricks step back.1

You could try turning around the outlet at the bottom of the downpipe about 45 deg towards the right, this should slow down the speed of the water flow and spread the water over a greater length of the gutter it may not then overflow..1

You might find a deep flow gutter improves it enough.1

Might be a daft question but does it really matter if your gutters overflow when there is a proper downpour?
We have a similar set up to the OP and when it really comes down heavy the lower gutter often overflows, but as this only happens maybe 4 times a year, is it really an issue ?0 -

The wall got soaked with water running down both the outside & inside. This caused the roof timbers to swell and push the end of the wall out (big stepped crack appeared in the blockwork). Good chance the timbers started to rot as well.So yes, guttering overflowing can be a serious issue that results in some expensive repair bills.
