That's right - No Fix, No Fee !

Experienced though I may be, Superman I ain’t.

However, my “No Fix, No Fee” policy insures you against my lack of Kryptonian powers!
Put simply, if I am unable to resolve your problem, nor adequately explain why it is irresolvable, then you pay me nothing.   

In addition, you should note that:

I charge no call-out fees within the mid-Argyll area.
My fees are very reasonable and based solely upon the time spent fixing your problem.
