How the site owner calculates your electricity and gas bills will depend on whether residents have meters.
Metered pitches – where the supply is individually metered, residents are only required to pay for the measured amount consumed plus a standing charge. The standing charge will apply to the site and then divided by the number of residents who are supplied.
Unmetered pitches – Where there are no meters on the site then all users will pay a share of the bill.
The Office of Gas and Electricity Markets (OFGEM) outlines the different methods as to how the site owner can calculate or estimate electricity resale charges. The site owner should make best efforts to use a method that is fair.
OFGEM guidance states as follows:
If the purchaser does not have a meter, or the meter does not accurately record the number of units used within each price band, the reseller must use his reasonable endeavours to estimate what proportion of the total bill each tenant should pay.
