How do you estimate my usage?

How do you estimate my gas usage?

When estimating your gas usage we base our calculations on these two key factors:

Annualised Quantity (AQ)

  • AQ is held on a centralised industry database and is reviewed yearly
  • Variations in weather
  • A typical domestic AQ is 12,000, which means that a typical domestic customer will consume 12,000 kWh yearly.

Annualised Load Profile (ALP)

ALP is how the industry adjusts your estimated usage based on seasonality.

The average customer uses 3.17% of their ALP in June and 14.38% in December. To estimate your consumption for June we:

  1. Take your AQ of 12,000 kWh
  2. Apply the ALP of 3.17% and
  3. Charge you 427.95 kWh of usage.

Please note: there is one ALP per region for domestic customers that is used in the example above. There are eight ALPs for business customers.

How do you estimate my electricity usage?

When estimating your electricity usage we base our calculations on two key factors:

The Estimated Annual Consumption (EAC)

The EAC is a calculation based on the electricity your property used over the last year and:

  • it is held in a centralised industry database
  • it is usually updated twice a year depending on how often your previous supplier submitted meter readings to the database
  • a typical yearly EAC for an UK average home is 3,100 kilowatts per hour (kWh).

Seasonality change (Profile Coefficients)

Have you even thought about how much electricity you consume in June compared with December? We adjust your estimated electricity consumption due to changes in season as follows.

On average, a domestic customer uses 6.38% of their EAC in June and 10.76% in December. To estimate your consumption for June we:

  1. Take your EAC of 3,100
  2. Apply the coefficients of 6.38% and
  3. Charge you for 210.54 kWh of usage.

Please note: there are two profile coefficients for domestic customers and six for business customers. The example above is for the most common domestic profile coefficient.
