Message to All Customers

Symbio Energy is ceasing to trade. Ofgem, the energy regulator, has appointed E.ON Next as the new supplier for its customers.

E.ON Next began supplying energy to all of Symbio Energy’s customers on 3 October 2021.

E.ON Next will contact customers over the coming days and again in a few weeks when the transfer has been completed and their accounts have been fully set up.

Customers don’t need to worry – their supplies are secure. Former and current customers’ credit balances are protected, and E.ON Next will contact customers if they need to determine the amount of any outstanding balance. Domestic customers will also be protected by the energy price cap when being switched to E.ON Next.

Current and former customers who are in debit to Symbio Energy should wait to hear from E.ON Next or Symbio Energy’s administrators who will talk to them about repayment arrangements.

Ofgem’s advice to Symbio Energy’s customers is not to switch, but to sit tight and wait until E.ON Next has been in touch. This will help make sure that the process of handing customers over to E.ON Next and honouring any credit balances is as hassle free for customers as possible.

How to Calculate your Electricity Usage  

To calculate your electric consumption, you will first need to understand how many units you consume in a day through the electric appliances you have within the house. You can simply multiply the consumption units of these appliances by the number of hours you use it in a day and you will have the number of watt-hours consumed each day by these appliances.   

  1. How to calculate Watt-hours Per Day  

For Example: 

Device Wattage (watts) x Hours Used Per Day = Watt-hours (Wh) per Day  

If you use a table fan that uses 20 watts for 4 hours per day, then the calculation is  

            20W x 4 hours = 80 daily watt hours (Wh) consumption  

  1. How to calculate Watt-Hours to Kilowatt 

The energy bills you receive are calculated in Kilowatt-hour consumption; you can arrive at it by dividing watt-hour usage / 1000  

For Example: 

Device Usage (Wh) / 1000 (Wh/kWh) = Device Usage in kWh, Kilowatt-hours = watt-hours ÷ 1000  

To know the kilowatt-hour consumption, divide the energy by 1000.   

The energy in kilowatt-hours is equal to the watt-hours divided by 1,000.  

A smart television using 500 Wh of electricity per day  

500 / 1000 = 0.5 kWh  

  1. How to calculate Kilowatt-hour consumption for a month  

For Example:  

Daily Usage (kWh) x 30 (Days) = Approximate Monthly Usage (kWh/Month)  

A smart television using 0.5 kWh of electricity per day  

0.5 kWh x 30 Days = 15 kWh/Month  

Let’s move to the monthly electric bill calculations  

You must know how much electricity the appliances consume on a daily and monthly basis. It may not seem a lot however when all the appliances in the house start adding up, the electric bills make a huge difference.   

How to calculate the charges towards the consumption of appliances.   

Cost per month = Monthly Usage (kWh) x Electric Rate (£/kWh)   

For Example:  

A smart television using 15 kWh/Month with an electric rate of £0.10/kWh  

15 kWh x £0.10 = £1.13/Month
