I have relied on Quigg Golden many times for numerous different matters. I have always found them to be selflessly honest in their advice; they have always advised what is in my best interest regardless of what would be best for their bank balance. When my own judgement has been clouded my emotion, I have been told this too (which is advice I am always grateful for later on down the line when the "red mist" has lifted).
I have found all of them approachable, and even their "top tier" (Mr Quigg) will take my calls, and return them if he can't.
I personally, have not found them to be overly fierce in their charges, and their have been numerous short calls where no invoices have been raised.
It is for all of the above they remain a valued consultant to us, and are relied upon solely to provide legal advice.
