One machine is suitable for a staff of ten to fifteen people. It costs ￡ 1300 to buy, or ￡ 11 per week to rent over 60 months.

Our company will carry out a weekly service, at a charge of ￡ 10. We can also refill the machine with drinks ingredients for an extra charge of ￡ 8. Some customers prefer to do this themselves, however.
