Electric meter reading not showing units used on invoices (caravan park)

eholt

Over the last three times site read meter then sent bill, there is no any units used shown so don’t know what we are paying .
s this legal or should there  units used should be shown 
please can any one relate to this

Yes, you should have an accurate bill based on units used - I presume the Park is sending you an invoice?

Does it show anything apart from a £xx.xx for a period?
