Many such charges are based on guesstimated percentages of main bills. A change to the operating practices of any one consumer alters not only their percentage but everyone elses. It is unusual for a user who uses an increasing share of the supply to volunteer this information whereas if a party uses a reducing share it is unusual for all the other users percentages to be adjusted.
Entelrail advocates the use of a kilowatt hours method of charge (cubic metres in the case of water) and will be happy to assist you with this.
For central heating Entelrail advocates a “square metre of floor area” based charge.
Even where overcharges are used it is essential that the basis of the assumption (usually the power drawn in the equipment and the hours of use) are accurately assessed.
Such principles are used by several suppliers – e.g. Network Rail major stations for “exclusive areas.”
Entelrail will be happy to audit the assumption used and negotiate charges.
One train operating company has saved over £100,000 on charges assessed by Network Rail major stations.
