Searching for Super Pitches

Does anyone know of a way to search for sites with super pitches (sometimes known as fully serviced pitches), i.e. pitches with elctricity, water and drainage. It is tedious to serch for pitches in an area, then to look at each one in turn, to see if super pitches exist on the site. Decrepit caravanners like me need all the labour saving assistance possible, to avoid spending half the holiday recovering from back strain!
