I will never tire of "I got your number from..."
I will literally* never tire of the phone calls that begin with "I got your number from..." I don't have an exact figure for you, but over 90% of our work is obtained through word of mouth. That means someone somewhere is recommending us onward having had a good experience - being asked by new clients to provide a quotation is a great sign for our business.
*note this word being used correctly here - using this word incorrectly grinds my gears more than a leak on a Friday afternoon.
Not everyone can get our number from a (very kind) friend, luckily for you it's just here for you.... 020 7993 8277.
