Oh they are great them Sky engineers.
I have 2 come to my house and say we cannot fit as we need special equipment to Chimney mount it as it need to be high.
NO WAY i thought as it also cost an additional £50.00 so sent them away, re ordered, had to bite bullet, sky say we will send standard installers and if they need to go on roof the will charge £50.00.
One guy came didnt mention anything about previous visit and he put it up at the front of the house without question.
Sky Engineers.
