Hi Rachel, The actual percentage of damp at skirting level being 'rising dampness' is quite low but it does happen . Water penetration , which could be from high ground levels or obstacles against the wall is the most common cause . Rain water penetration is next , defective plumbing comes in third , plaster thickness is fourth and rising damp is the last one to consider . You might need a to have this inspected by an I dependant party , try to find a CSRT surveyor . Are you within the M25? Can you send me pictures of the inside and outside ?
