Units of additional expenditure

Calculation of labour and material costs on a time-and-materials basis. For a specific enquiry, please ask for the required number of units to be charged. The minimum charge for alterations to dimensions is one unit. The more precise the specifications, the higher the charge. If two dimensions are specified exactly (exactly meaning ± 0.5 cm), three units must be selected.
