What is an EAB?

EAB - Estimated Annual Bill

The CRU (Commission for Regulation of Utilities) have asked all suppliers to provide an estimated annual bill as an indicator to understand the best tariff options available to customers on all their marketing and advertising materials. This information is provided to assist customers in making the most suitable choice for their energy needs.

The CRU have determined that the typical customer will consume 11,000kwhs of natural gas and 4,200kwhs of electricity per year, thus this is the figure Flogas will base the EAB on, however you should note that your actual energy usage may vary from same.

In line with guidance from the CRU the EAB does not include any value from, cashbacks, loyalty points, vouchers, gifts or any other such add ons.

The EAB is calculated by taking the average consumption figures and adding this into a calculation with the gas/electricity unit rates, standing charges, carbon tax (gas), PSO Levy (electricity) and VAT. Please see below examples:

Electricity

Unit Rate x 4200kWh 
Plus Standing Charge (Annual) 
Plus PSO Levy (Annual) 
Plus VAT

Gas

Unit Rate x 11’000kWh 
Plus Standing Charge (Annual) 
Plus Carbon Tax (Annual) 
Plus VAT

The above electricity calculation is based on an Urban customer with a standard 24 Hour meter. EABs will vary depending on customers meter type and property location. For customers with a Day and Night meter, the 4,200kWhs are apportioned as 62% Day and 38% Night.

The consumption used to calculate our Standard Smart meter EABs are apportioned 54% Day, 10% Peak and 36% Night for Urban customers and 55% Day, 11% Peak and 34% Night for Rural customers, using the CRU approved figure of 4200kWh.  

See our example below of how we calculate Smart EABs:  

Standard Smart EAB

Day Unit Rate x 2268kWh (or 54% of 4200kWh) 
Peak Unit Rate x 420kWh (or 10% of 4200kWh) 
Night Unit Rate x 1512kWh (or 36% of 4200kWh) 
Plus Standing Charge (Annual) 
Plus PSO Levy (Annual) 
Plus VAT

The above calculation is based on an Urban customer on a Standard Smart meter tariff. EABs will vary depending on a customers chosen Smart meter plan.  ban customer on a Standard Smart meter tariff. EABs will vary depending on a customers chosen Smart meter plan.
