• Energy Jargon Buster

    There are lots of phrases and words used in the energy industry and some are easier to understand than others. We thought we’d put together a handy list of phrases and acronyms you might not recognise straight away. Are we missing any phrases from the list? Let us know in the community:

    The Energy Industry

    (The) National Grid
    A company that connects homes to energy supplies, both gas and electric. They own the electricity transmission system in England and Wales, as well as operating 4 out of the 8 regional gas distribution networks in the UK. They are also responsible for fitting smart meters and attending meter fault callouts.

    Big 6
    The 6 largest suppliers of energy in the UK: British Gas, EDF Energy, E-ON UK, nPower, Scottish Power and SSE.

    DNO (Distribution Network Operator)
    A company that is licensed to distribute electricity to consumers in the UK and are responsible for getting the electricity to your meter. Ofgem approves the license.

    Erroneous Transfer
    When an energy supplier switches a property by mistake. If this occurs, you should always contact the supplier straight away. If an energy supplier has accidentally switched your energy, they will contact you to sort it out.

    The Office of Gas and Electricity Markets. They regulate the energy market, ensuring that all energy suppliers adhere to guidelines set out by the government.

    A company responsible for the distribution of gas to consumers in the UK. The largest Transporter in the UK is National Grid.

    Energy Usage

    Annual Quantity (AQ)
    Your gas usage forecast for the year. An EAC (Estimated Annual Consumption) is the same thing, but for your electricity usage. We use this to forecast to create your monthly statements if you do not supply meter readings.

    Estimated Annual Consumption (EAC)
    When you join a new supplier, a company may use an estimate of your usage if they do not have up to date and regular meter readings. An AQ (Annual Quantity) is the same thing, but for your gas usage.

    Energy Measurements

    Calorific Value
    This is a measurement of how much energy something produces when combusted. In the case of energy supply, this relates to how rich a gas supply is. It can vary around the country and by gas supplier.

    kilowatt hour is a way in which energy is measured. You'll see your usage on your statements labelled with how many kWh you have used.

    Unit rate
    A supplier's charge for each kWh a consumer uses. In Pure Planet's case, you can see this on your monthly statements.

    Energy Meters

    This stands for 'Meter Point Administration Number'. It's a unique electricity supply number for your property. You can find it on your statement in the ‘Electricity’ section (page 2 of 3). In the diagram below, you’ll see the MPAN on the bottom row, as it will be shown on your statement:

    This stands for 'Meter Point Reference Number'. It’s your gas supply’s unique number. You’ll find it on your statement in the ‘Gas’ section (if you have a gas supply with us that is). It will look like this:

    This stands for Meter Serial Number. This is can be found on the front of your electricity and gas meters. It’s a unique way for energy suppliers to identify your meter.

    Pre-payment meter
    A meter that allows you to pay for energy up front. For very low usage, it can be a money-saver. However, it tends to be a more expensive option for most consumers. With smart meters pre-payment will become cheaper and more likely to be a lifestyle choice similar to pay as you go in the mobile phone industry. At Pure Planet, we're not quite ready to support pre-payment meters. We're working to make this available in 2019.

    Smart Meters

    IHD - In-Home Display
    A small electrical device with a touch screen. It pairs with a smart meter to show info about your energy use.

    SMETS1 Smart Meter
    A first generation smart meter, which sends meter readings automatically to an energy supplier. Some models of SMETS1 meters only work as smart meters with the energy supplier who fitted it. If a person switches to another supplier, their smart meter will still function as a meter, but may not send readings automatically. Got a SMETS1 meter? More info here.

    SMETS2 Smart Meter
    A second generation smart meter. They send automatic readings to an energy supplier - regardless of which company it is and where a person switches to and from. More info about SMETS2 here.

    Tariffs and Charges

    Direct Debit
    An automated payment system that transfers cash from your account to a company or organisation on a regular basis. Most suppliers prefer to use this method, from energy suppliers to mobile contracts etc. We operate under the Direct Debit Guarantee.

    Dual fuel
    If have a gas and electricity supply from the same supplier, it is called dual fuel by most suppliers.

    Dual Fuel discount
    A monthly credit applied to your account if your gas and electricity are both supplied by Pure Planet. It will show on your monthly statement and in the app.

    Economy 7
    An electricity tariff where electricity is cheaper at night. Pure Planet does not currently offer an Economy 7 tariff.

    Economy 10
    An electricity tariff where electricity is cheaper at certain times of the day. It is much like an Economy 7 tariff, but a supplier can choose which times are ‘off-peak’ and it totals up to 10 hours a day, hence the name. Pure Planet does not currently offer an Economy 10 tariff.

    Standing charge
    A cost that an energy supplier charges a consumer to link their property to the mains supply. In Pure Planet's case, this is included in your membership fee.
