The Royal Institution of Chartered Surveyors released their latest report. The BBC News picked it up:

Traditional art is proving popular for high-end buyers as prices in the UK arts and antiques market continue to rise, a survey has found. Oil and watercolours have performed well with works priced at more than £50,000 rising in value, surveyors say. But the survey by the Royal Institution of Chartered Surveyors found that the rise was driven by traditional, rather than contemporary, art. More affordable art was outperforming the higher end, it said. Prices in the first three months of the year were rising owing to a lack of supply of art, the survey found.
