hi Cluskerm,
I have always charged the same for mobile as I do for premises. But now that I am renting 2 rooms, if someone wants a mobile treatment then I am going to charge MORE for a home visit. I have to pay rent on 2 rooms, so going to someone elses home is actually doing me no favours.
One of the rooms I rent from is a chiropody clinic, he does domicillary visits once a week and he charges a lot more for a home visit, think its £7 more.
I will add £2.50 onto any treatment of a home visit, and if its over a certain distance then I charge more anyway.
If anyone questions the price, I briefly explain that I have to pay rent, petrol, etc.
I also do talks and demos, and if the venue is a certain distance, ie I live in Durham, and I do workshops at Alnwick Gardens which is about 50 miles away, I charge petrol expenses and an extra hour work although it takes me 2 hours to travel there and back.
