How do we determine the volume of washroom equiptment required?
A. We will advise of your legal requirements and the facilities that we deem to be adequate to suit your business needs, we also ensure that this is reviewed with our customers throughout the duration of the contract to reflect any increases or decreases that may occur in your washroom requirements.
