I'd think that'd be hard to justify at those figures. I doubt you should really even be accounting for the costs of one call out per customer, as I'd certainly be hoping that the average was far less than one call out per customer.It was our accountant that suggested it and it seemed a very good option to us, just wondering what other people thought and what figures they were using. She felt between ÂŁ300-ÂŁ500 per job was justifiable.
something more like ÂŁ75-100 per customer would seem a bit more realistic and less likely to be challenged to me, unless you also warranty the equipment yourself on top of the manufacturers warranty.
