Oilies - Reasonable rate for servicing a twin burner range

[WHPES]

As in the title, I am interested in what the going rate for servicing one of these is. I have always been unsure what to charge.

Double a normal, plus extra as they are a pain in the backside.

£180 min is my aim, unless I know the range and its history, ie is it easy to get the hot spot off and gain access etc etc.
