Damp on internal wall and problems on external rendering


Im looking for some advice on the damp patches on one of my walls. Last year I noticed patches with the salt which made lots of the paint flake. It bubbled and in the end to make it better I scraped it all back which was falling off. Then painted over with some damp proof paint, the skirting boards were wet and mouldy too.

The damp on the walls was on a corner and also patchy on other walls. From the internal pic you can see it varies in height. It has come back and obviously the quick fix wasnt the best option. The patchy colours on the wall, its not all down to damp, there was a slight difference in colour due to the paint texture from when i repainted over the damp paint. It has got worse recently since rained so know its an issue.

The wall behind has a few exposed bricks with no rendering on. At the bottom of the wall, there is 4-6inch 'gully' between the external wall and the footpath paving. When it rained the otherday, this gully got full of water, i brushed it out and wondered if the water is getting in through here and then rising into the brickwork.

Also in certain parts of the rendering, there are cracks, from pics you can see well i think it must go up majority of the side of house.
One of the bedrooms upstairs I can see what looks like damp patch on wallpaper high up, which is on this same side of the house too, probably from the same issue.

Its difficult to know what potentially needs doing. If I just need all the rendering redone, if i had to do this side, id have to do the entire house. My previous house, I had rendered and there were none of these damp issues, cost me 5k :cb

Any experts can offer any advice on the internal and external issues, if i need to consult damp specialists or if just require the house to be rendered again. Thankyou for any advice given. Would like to know what Im looking at before getting experts aka quotes

The first problem is that someone painted the brick. Now moisture is getting trapped everywhere.
