You probably know this is coming, but What kind of rooms are fires likely to start in?

Yep, I know... It's a very vaguely worded regulation! The kitchen would have to be the most obvious choice, but beyond that it's open to argument.

The 23' leaves plenty of room for maneuver though. In most new British homes that would allow a detector in or near the kitchen and it would be well within that distance of the living room & dining room doors as well.

In small single-story homes, quite often just one detector would be within this range and could be within 10ft of the bedroom doors as well.

On two-story ("storey" in British), there's rarely more than one on aach floor, except for large houses.
