I am thatched - or, at least, my house is! Yup, things live in the thatch, sparrows nesting currently, swifts will soon be building their nests under the eaves, a bat roost, voles - brilliant and all are welcome, it is their home too.
Virtually uninsurable? Not so, one simply has to find a specialist insurer and, yes, premiums are slightly higher, but not significantly so.
Replacement? About every 20 years for straw thatch or 25 years for water reed at around £10/square foot for the finished job. And ridges ideally need replacing every 10 years.
Fire risk can be mitigated by treating with fire retardant or intumescent coatings. And regular chimney sweeping, but that should be a given anyway, regardless of whether thatched or not, if one has an open fire or woodburner.
Well insulated - cool in summer, warm(ish!) in winter and the distinct advantage of having no gutters to clean or maintain.
It's a "yes" and a 👍from me!
