Most attics in Meath can be converted in some form, but suitability comes down to two things above all: how much usable head height you have, and what type of roof structure sits above you. These decide not whether a conversion is possible, but which approach fits and what it is likely to cost.
The single biggest factor is head height. As a practical rule of thumb, you want roughly 2.4m from the existing ceiling joists up to the ridge to have good options. With that, a straightforward Velux conversion may give enough standing room. Where the existing roof lacks height, a dormer or a hip-to-gable conversion can create head height that is not there now.
Roof structure matters just as much. A traditional cut roof, common in older houses, tends to have an open, convertible space. A modern trussed roof, common in newer estates, fills the attic with structural timber webbing; it can still be converted, but it needs a structural engineer to design new steels and floor structure, which adds cost.
Other things shape the layout: chimneys, water tanks, and the roof pitch all affect where a room and stairs can go. The honest answer to suitability only comes from a proper look.
