Awful experience! Having submitted my accurate measurements for a recess blind, they have sent me a blind that does not fit. They make a 4cm assumption for mechanism and brackets...however the manufacturer suggests 3.5cm and having measured it in real life, it's actually 3cm. So my blind is 1cm too short at its maximum! I have written to Blinds4UK but they hide behind their principles and make no allowance for the contradiction with the manufacturer. They have not delivered the service contacted for and I must resort to small claims to get anything back. So please, please shop elsewhere if you're looking for recess fitted blinds. There is not much you can do with a blind that's too small! The customer service here is poor and they are nothing but a distribution arm for the manufacturer, so will never have the margins to put right any errors. Shop elsewhere!
