Billing disputes are not uncommon when busy pub landlords are approached by sales brokers as they move into new premises.
Although the cost you were quoted must have been an estimate, they should have clearly stated during the sales process on what unit rates of usage they were basing it. No supplier should guarantee you will pay a fixed amount each month regardless of how much you use, especially as you had no consumption history for a quote. You should always request written confirmation before accepting a quote.
The supplier should bill you on actual meter readings and not estimates. Request a reading or provide them with your own immediately. An actual reading will give you and your supplier an accurate picture of your energy use.
Ask for the price of a meter check (this varies with meters and suppliers) and arrange one. This ensures your meter reads accurately and only records usage from your part of the premises. Sometimes a meter measures other premises or rooms that have nothing to do with your property, due to building remodelling where the meters were not changed.
Once you agree the amount you owe, you could ask to spread payments over a period. This helps with budgeting.
If you are unhappy with your service, ask to be released from the contract. Be aware that as you have agreed to a fixed-term contract, it is under no legal obligation to let you go until expiry and may charge an early termination fee.
Finally, remember that you cannot be held liable for any amounts owing from the previous tenant of the pub.
