None in the UK for new parts - Honda penalise any
dealer who steps out of line by offering parts at less
than list price allegedly.  I have ordered some parts
from the states, but less places are shipping international
orders now.  Also, you have to watch for LHD/RHD
incompatibilities e.g. door lock actuators / window
regulators.  If it's a part that doesn't often fail, try the
scrapyard networks.

I dont live in the U.K. but looking things up for a relative there, I came
across this http://www.nipponautomotive.co.uk/ - no experiences to relate
about them.  They don't publish prices on the site -- only on request by
e-mail -- but I suspect they'll get their legs broken anyway.:-)

For new parts expect to pay dealer price. I buy mine second hand from
breakers - try www.hondaspares.co.uk. You can pick low mileage parts at
very good prices as long as you are prepared to the risk. I had my
drive shafts, alternator, ecu etc from them.
