Its look like there is a double discount for Boardman bikes on halfords website.
You can have Boardman CX Comp Bike 2014 for £539.99 but price on chekout is £485.99. You can have also another 22% off using British Cycling and voucher discount so price would be around 380 pounds.http://www.hotukdeals.com/deals/22-off-any-purchase-halfords-1603626
Bought one 2 months ago for around 420 using BC and voucher discount.
Boardman Road Team Carbon Bike 2014 should cost around 630 after all discounts ;)
