B&Q have 15% off all Designer and towel radiators until 18th September.
As an example, the Jaga Iguana Circo radiator has been reduced from £239 to £203.15.
I know B&Q have recently had 15% off all items over the bank holiday period, however they missed out Wednesdays (i.e those offers ran from Thursdays to Tuesdays). All OAP's get a 10% discount on Wednesdays therefore the price then drops to £179.43 for the above mentioned item (which comes with a 10 year guarantee).
B&Q also have 25% off conservatories and garden buildings too!
