hi
i have had a conservatory installed ,the contract was for pilkigton k glass and at the time of selling the conservatory i was told its the best hence costs more
the glass fitted though is gardian which conforms to uv levels etc but can the fitters change the glass without informing us
trading standards seems to say that we have to prove that pilkingtom k glass is moe expensive than gardian, is there any way of doing
thanks in advance for help
