Recommended nanny agencies?

[Norfolkvillas]

Apols if I'm posting this in the wrong section, but we are sadly leaving our lovely nanny share in September and are looking for a live-in nanny. Can any Family Room-ers recommend any reputable nanny agencies who don't charge extortionate fees? I seem to remember several recommendations from a while back for a lady based somewhere outside of London (Surrey? Kent?) but think admin my have deleted the posts as they were quite old.

Any help greatly appreciated.

Thanks!
