Oh yeah ANd you are suggesting £20 BEER MONEY, this indicates that you are not putting this through your books, should the cust try and claim on your liabillity insurance, they will find that they wont be able to because your insurers will claim that you were never at their property.
NONE OF THE ABOVE GIVES A PROFFESSIONAL IMAGE
Cost of PL Insurance for my business £1,500 per Year
Maintaining my Engineers Gas Safe £5,000 per Year
Rent of Office /Workshop £6,000 per year
Contract Hire 4 Vans £12,00 0er year
Annual road fuel Bill £8,000 per year
Business Rates £2,000 per year
Vehicle Insurance/Office insurance £4,000 per Year
Payroll £84,000 Per Year
ADD THAT LOT UP. and then tell me that £70 is unreasonable
