• Different meter types

  • We've put together some information on the most common meter types and the homes they are best suited to. You can also find out how to read your meter and how to let us know your meter reading. Accurate meter readings help to ensure you only pay for what you use.

    Please be aware that any 'off peak' times will vary depending on where you live and the type of meter that you have. Some meters will automatically adjust themselves when the clocks go back or forwards, meaning that any appliances you have set on timers won't need to change. Other meters won't change automatically, so you'll need to manually adjust the timers on your appliances by an hour instead.

    If you have any questions about your meter or how it works, please contact us and we'll be happy to help.

  • If you have gas or oil-fired central heating

    What is Standard?

    Standard meters are ideal if your home has gas or oil-fired heating. The meter records all the electricity you've used at a single rate. They're also available as a Pay As You Go meter

    What is Evening and Weekend?

    Evening and Weekend meters are ideal if you’re out most of the week during the daytime.

    These meters have two readings; one for day and one for night. Energy used between 7:00pm to 7:00am Monday to Friday and from 7:00pm on Friday to 7:00am on Monday is cheaper than energy used during the day.

    These timings may vary slightly depending on a variety of factors including your postcode, timeswitch (signal strength) and Daylight Savings Time.

    This tariff is only available in some areas. Contact us if you'd like any more information.

  • If you have all electric heating

    What is Domestic Economy?

    Domestic Economy meters are ideal if your home has electric heating. Ideally, they're used with storage heaters and water immersion heating.

    These meters have two readings, a 'day' or 'normal' reading and a 'night' or 'low' reading.

    The specific day and night periods on a Domestic Economy meter vary between different regions and at different times of year. Usually the night usage is recorded between 11:30pm and 7:30am in the winter and 12:30am to 8:30am in the summer. Some regions use radio teleswitching to vary the timing. This uses data superimposed on the 198 kHz BBC Radio 4 long-wave signal.

    To find out the specific times for your meter, please contact us.

    Storage heaters usually charge automatically during the 'night' or 'low' usage times, which means you can use timers for things like dishwashers and tumble dryers. They're also available as a Pay As You Go meter.

    What is Total Heating, Total Control (THTC)?

    Total Heating, Total Control meters, or THTC for short, are great for your home if it has electric central heating and you’re at home most of the day. They’re only available in certain areas of Scotland.

    To make the most of this meter, storage heating needs to account for at least 60% of the way you heat your home - it has to be the way you heat the main parts of your home. The main way of heating your water will also need to be done electrically, which will again be on your low price. All your other electrical usage will then be recorded on a different meter.

    You'll get between five and twelve hours a day from your storage heating. We find out the best times to put it on for you by regularly checking the weather forecast. This means that you’ll have heat when you need it most, without having to worry.

    If you have any more questions about your meter, then contact us and we'll be happy to help.

    What is Storage Heating Control (SHC)?

    Storage Heating Control (or SHC) meters are designed to be that extra boost you might need by running alongside your regular heating, whether that’s electric or gas. They’re only available in certain areas of Scotland.

    You get eight hours of low cost heating include a minimum of three hours between 10pm and 10am and then a minimum of two hours between 10am and 10pm. SHC is ideal if you have one or two rooms, for example, that use storage heaters, but the rest of your home has gas central heating. The rest of your usage will go through a different meter.

    If you have any more questions about your meter, please contact us. We can have a chat about it and find out.

    What is Economy 10?

    Economy 10 is an energy tariff that gives you 10 hours off-peak electricity. These off-peak hours are charged at a lower rate. This allows you to heat your home and hot water with your cheaper rate electricity and reduce the use of the more expensive daytime rate, when your home may need less heat. The off-peak hours are spread throughout the day so they're practical too.

    How Economy 10 works  

    • Economy 10 is specifically designed for homes with direct acting electric boiler systems, fluid filled electric radiators or air/ground heat pumps.
    • In addition to your heating and hot water, all electricity you use at the off peak times is charged at the lower rate (such as washing machines, dishwashers, tumble dryers and so on).
    • You will only receive one energy bill, making payments clearer.

    Prices and times  

    Your Economy 10 tariff is made up of three prices: a fixed service charge, a standard price and a lower price for off-peak times. You can reduce your costs just by using electricity during the off peak times and avoid, when possible, using the energy during the peak times.

    Regional times may vary slightly according to the area you live in. If you'd like more information on the specific times in your area, contact us to speak to one of our advisers.

  • If you have a different type of meter

    What if I have a different kind of meter?

    You may have an older meter type which we haven’t mentioned here. A lot of these older meters have their own tariffs or plans which were created just for that type of meter. Most of these older meter types involve more than one meter; one to record your general electricity usage and another to record your heating.

    These meters aren’t available if you’re a new customer, but we still honour these ‘preserved’ meter plans if the meters are already in place in your home.

    If you’re not sure what type of meter or plan you have, then contact us and we’ll let you know.

  • I need more help with this

  • I want to know about meter changes and storage heaters

    If I change to a different type of meter, will I be charged?

    We don't always charge for changing a meter, it depends on the type of meter you intend to change.

    For example, if you wish to change from a Pay As You Go meter to a credit meter, a credit assessment is required and a £52 charge. However, there are a number of customers, including vulnerable groups, that are exempt from the charge. Please contact us for more information and one of our expert advisers will be happy to help and answer any questions.

    What if I want to change my pricing plan and it requires a meter change?

    If your meter needs to be changed when you change your price plan, we can arrange an appointment with you. Contact us to talk about changing your meter.

    How do storage heaters work?

    Check out our storage heaters page for information about how they work and advice about how to get the most out of them.

  • Switching supplier

    Can I switch energy suppliers?

    Many people whose home has a different type of meter think they're not able to switch suppliers, but this isn't true – you can switch if you want to. However, some meters are unique to us, so you might find that other energy suppliers won't match your tariff without some additional rewiring.

    What information do I need to switch suppliers?

    If you want to switch, you'll need your unique Meter Point Administration Number (MPAN), which suppliers use to register your home. Some meters might have two MPANs, and you'll need to give both numbers to the new supplier at the same time. You can find your MPAN(s) on your electricity bill, or you can contact us to find out what it is.

    How do I know which tariff I'm on?

    Your tariff should be clearly shown on your bill. If you're still not sure, please contact us and we'll tell you.

    Because your meter is specific, you might not find your tariff on energy comparison sites. If you want to switch, contact your chosen supplier to check if they will support your meter and ask for a quote. You can then compare prices and decide for yourself if switching is right for you. 

  • I have questions about Domestic Economy meters

    How does Domestic Economy work?

    Domestic Economy gives you eight hours of cheaper electricity overnight. It’s designed for homes with storage heaters and water immersion heating as you can charge them during the night. Your meter will have two rates - a day and a night rate. Each will record all electricity used during those times.

    The amount you pay per unit on the day rate is more expensive than on Domestic Standard, but the night rate is cheaper, letting you heat both your home and your water for less.

    What are the Domestic Economy ‘off peak’ hours?

    The specific day and night periods on a Domestic Economy meter vary between different regions and at different times of year. Usually the night usage is recorded between 11:30pm and 7:30am in the winter and 12:30am to 8:30am in the summer. Some regions use radio teleswitching to vary the timing. This uses data superimposed on the 198 kHz BBC Radio 4 long-wave signal.

    To find out the specific times for your meter, please contact us.

    What happens to the 'off peak' times when the clocks change?

    The 'off peak' times will vary depending on where you live and the type of meter that you have.

    Some meters will automatically adjust themselves when the clocks go back or forwards, meaning that any appliances you have set on timers won't need to change. Other meters won't change with the clocks, so you'll need to manually adjust the timers on your appliances by an hour instead.

  • I have questions about Economy 10 meters

    How does Economy 10 work?

    Economy 10 gives you ten hours of cheaper electricity in a day. It’s specifically designed for use with electrically-heated wet radiator systems.
