A trade falls victim to technology and
changing tastes
FOR the past four decades Britons have
been hooked by “Antiques Roadshow”.
a television programme in which dusty
old chairs discovered in a corner of some-
body’s attic are occasionally revealed to be
worth thousands of pounds. Over 5m peo-
ple watched the episode on May 11th. But
while the format of the show has hardly
changed over the years, the antiques mar-
ket has. Technology, immigration and
changing tastes mean the televised ideal of
the trade is dating quickly.
Antique shops used to dot British high
streets, particularly in southern England.
Dealers-usually middle-aged men who
inherited the business from their father-
would build relationships with rich cli-
ents, selling them tasteful things they ac-
quired at country auctions.
Now many shops are closing and dealers are disap-
pearing. Between 2003 and 2009 the num-
ber of dealers fell from 8,500 to 6,600. The
guide that listed them has since gone out of
print, but falling memberships of trade i.bo~
dies like the British Antiqtie Dealers’ Asso-
ciation suggest the decline continues.
Many relied heavily on a tourist marketthat has shifted over the past decade. Be-tween 2003 and 2013 the number of Ameri-cans visiting London fell by 9%. AnthonyOutred, a dealer, remembers shippingcrates of antiques to America. That is rarernow. Tourists from Asia and Europe aremore numerous, but they are much lesskeen on English furniture.
Rising rents and business rates, espe-cially in London, have made thingstougher, says Sarah Percy-Davies, the for-mer head of LAPADA, another trade body.The internet has allowed dealers to reachmore customers, but has also increasedcompetition. And the ready availability ofauction prices online means fat markupsare harder to get away with. Older buyersin particular are becoming better at re-search, complains one dealer.
