The energy industry is renowned for its jargon, buzzwords and acronyms. I have come across 200+ during my time at amber energy!

These buzzwords and acronyms are technical terms developed to help professionals in the industry communicate quickly and simply with one another.

On the other hand, buzzwords and acronyms are now used in our everyday language for people to appear 'cool' or to deliberately confuse an issue.

'YouGov found 75% of people find energy bills confusing?'

Hopefully this blog will shed some light on the jargon, acronyms and buzzwords found on your bill:

Calorific Value (CV)

'Calorific Value' (CV) is a scientific term used to describe how much heat is generated when a known volume of gas is completely burned away. Put simply - the CV measures how 'useful' your gas is, so your supplier can charge you based on the quality of the gas that is supplied to you.

Estimated (E) or actual (A) readings

If your meter reading has been estimated - then your energy supplier has assumed your usage for the period in question, based on your energy usage patterns in the past.

If they don't hold this information, they will use national average figures. If you've had a meter reading recently, then your usage will be marked as 'actual' and not estimated.

This isn't always obvious - and might only be denoted by a capital 'A' for 'actual' or 'E' for 'estimated'.

Kilowatt hours (kWh)

A kilowatt hour is the standard measurement of energy that your energy supplier will use to bill you. A kilowatt hour refers to a person using 1000 watts of electricity for 1 hour. Your prices will be set per kilowatt hour (kWh) of energy you use.

Meter point administration number (MPAN)

Your meter point administration number will often be referred to as your MPAN or your supply number. It can also be referred to as your 'S' number. This number is assigned to the electricity meter at your property to identify it, and can be found on your electricity bill.

Meter point reference number (MPRN)

Your meter point reference number will often be referred to as your MPRN number. This number is assigned to the gas meter at your property, and can be between 6 and 10 digits long.

Correction Factor

The volume correction factor of 1.02264 takes into account the changes in the volume of gas based on temperature and pressure.

Climate Change Levy (CCL)

CCL is a tax on the taxable supply of specified energy products (taxable commodities) for use as fuels that is for lighting, heating and power, by business consumers including consumers.
