It will be a really generic survey spanning various issues. @York will be pretty close with his rationale. The emergency services know what their response time was and what it should have been, they know the most cost effective ways improve fire prevention, they will be able to report on issues with access. That's really a job for an inquest, enquiry, or case review. You can't really ask the public about what they think is important with things like emergency response and fire prevention, or access. When you ask Joe Public's two pence on things like that it can really muddy the water as it's an emotional response rather than an informed one. If asked I would say a sprinkler system would be the most important thing in preventing the spread of the fire and support spending a ton of money in putting them into every high-rise. In reality I have no experience with fire prevention in high-rise buildings and have no clue if it is the most cost effective way of saving lives (would spending that money on fire retardant wall insulation alongside external fire escapes be better for example). The cynic thinks this will boil down to something like "we spent £Xmillion on support for Grenfell and it's residents while decreasing your bin collections, reducing park maintenance, and increasing parking permit costs because we felt that was more important and respondents to our resident's survey agreed".
