I finally remembered to take photos. The brick is my garage. Right up against that is neighbours driveway. I need to do a bit more work to divert the water away from the exposed corner which is where most of the water comes in.
Neighbours driveway is too high

Probably tanking the inside will be the right route to take, a single skin of brick should never be thought of as waterproof anyway no matter what the external ground level is, that's why we have cavity walls.
I suppose that's bound to be a risk when your building is right on the boundary.
You could build a dwarf wall inside your garage, with a drained cavity, but it would have been nicer to have the gap outside.
If your neighbour ever has the drive relaid you could offer to pay for a retaining wall or drain.
I have a neighbour whose gardener likes to throw compost and rubbish by my fence, but luckily doesn't mind if I rake it level. In a previous house I had concrete gravel boards going up to compost heap height so I could do that without causing damage.

Having re-read the thread, I think you would do well to cut a channel, and fill it with large cobbles or pebbles (these drain better than gravel or shingle) to stop anyone falling in the little trench. You can dress the top layer with attractive chippings. Have you got a big angle grinder? You can hire a cutter with a big wheel as used by road menders, but don't cut your foot off.
If the trench is big enough you could put perforated drain tube in the bottom.
You can treat the bottom of your wall with synthaprufe or cut dpm to reduce water transmission.
Landscape fabric will prevent mud washing in and blocking the porous fill.

All good ideas. Unfortunately I don't have the time or the money to go through proceedings to do any major work. I'm rushing to get new tenants in. I have cut channels to deepen the gulley, and just figuring out that the frontmost corner is taking the brunt of the surface runoff and the dpc and below is unrendered. I'm going to build up a cement patch there which should keep 90% of it out. Then will give the inside a good dose of waterseal. I'm also removing the plasterboard to waist height so the damp doesn't wick up the walls.
