My walls in Brighton were generally impossible to not drill a huge wide hole in, because they were made of crumbly stuff with a random flint element, which tended to send the drill bit off sideways. My solution was a multi-stage process which went: 1) drill a big messy hole, 2) saturate the inside of the hole with diluted PVA, which binds the surface layers together a bit and eliminates dustiness, 3) once that had dried, backfill the hole with polyfilla, 4) once that had dried, drill a neat hole in the polyfilla. The whole process then took a couple of days, off and on, but seemed to produce solid enough results.
