To provide any form of instrument approach in the UK you need ATC with a validated approach controller on duty. Lydd are installing the ILS with a view to going full ATC - that's the only way they'll be allowed to use it.
I'm with Timothy on this one. Remote monitoring in countries that allow it is fine, but the runway incursion threat would be my main worry. To have that plus an unmonitored ILS starts throwing in too many variables in low vis conditions.
