How are water charges calculated?

There are three basic charge elements which apply to most business premises – water, waste water and drainage.  These charges are further split into a fixed rate and a volumetric rate for water and waste water, and into individual elements of property drainage and roads drainage.  This makes a total of six billing elements, which are explained fully below.

If your property has a water meter, your water and waste water charges are based on consumption recorded in cubic metres (one cubic metre = 1,000 litres) by the meter.  If you don’t have a water meter, your charges are based on the rateable value (RV) of the property as determined by the Scottish Assessors Association.  If you would like a water meter, please contact us and we will liaise with Scottish Water to have a meter installed at your property free of charge. Drainage charges for all customers are based on the RV.

Fixed water charge:  this is an annual fee based on the size of your meter, and covers the upkeep of the pipes and pumps that supply your water.  If you do not have a meter, these charges are based on the RV of the premises.

Volumetric water charge: this is a charge for the amount of water you have used, measured by your meter.

Fixed waste charge: this is an annual fee based on the size of your water meter, and covers the upkeep of the pipes and pumps that remove waste water from your property and the maintenance of the waste water treatment works. If you do not have a meter, these charges are based on the rateable value (RV) of the premises.

Volumetric waste charge:  waste water is the proportion of your water that goes down the drain and this is usually charged at 95% of your recorded water usage. In some cases this figure can be reduced, depending upon your type of business, and with the permission of Scottish Water.

Property drainage charge:  as you are connected to the public water and sewerage system, you are charged for the cost of collecting and treating rain water from your property. Charges are based on the RV of your property, even if you are exempt from commercial rates.

Road drainage charge:  this covers your contribution to the public roads drainage system and keeping the roads free from flooding. Charges are based on the RV of your property, even if you are exempt from commercial rates.

VATVAT is chargeable at the standard rate on clean water charges for all customers whose main business activity falls within sections 1 to 5 of the 1980 Standard Industrial Classification (SIC) as used by Companies House.
