If Adrian Flux know that your best quote (ie the one they try to beat) is from HIC then they will not quote you. When i told them my best quote was from Highway (through HIC, but i didn't mention that) and was asked to email them proof, the girl called back and said they couldn't continue with the quote "as i had failed to mention that the price they were beating was from HIC", their sister company. Her words were "i can get in big trouble if they find out i've beaten an HIC quote", which is pretty rediculous tbh......
