Domestic Tariff Switching

Why should I switch tariff?

Green House


More than 50% of the UK population pay too much for their energy bills without realising that hundreds of pounds of savings could be just a five minute phone call away. Greenvision Energy can significantly reduce your energy bills in a matter of minutes by simply switching tariffs or by replacing your old pre-payment meter. As a registered Green Deal provider, we know several ways to save every customer money without hassle, no matter their current energy provider or tariff. What’s more, every installation carried out by Greenvision will automatically get a free tariff check to make sure that you are on the best deal.

Switching tariffs is simple, painless and quick to do. We’ve saved customers over £200 a year in just 15 minutes by contacting their existing energy provider and moving them from a standard tariff to a fixed rate tariff. If we offered you £200 for a 15 minute call, we know you’d take it!



Replacing your meter

Fuel Poverty

We can also save you money by replacing your pre-payment meter with a standard one. For some people, a pre-paid meter can be more convenient if they don’t have access to a bank account and email address, or for people who like to budget strictly. However, by having a pre-payment meter, you could be paying up to 15% more for your electricity. This is because pre-payment meters normally only give you access to one tariff and they charge a premium for electricity used. As long as you don’t have any debt on the meter, replacing your pre-payment meter to a standard one is usually at no cost. Once this simple change has been made, you’ll be able to access all tariffs and start saving money!

How do I get the best deal from my energy provider?

If your building society reduced the interest on your savings, you would probably look for a better deal. So why not do the same with your energy tariffs? Tariff switching should be done every year, especially since many people forget to contact their energy provider after fixed rate deals or special offers have ended. See our Top 3 Tariff Switching Tips below.

Greenvision Energy's 3 Top Tariff Switching Tips

Number 1: Phone your existing supplier and ask for a better deal. It may sound too easy to be true, but energy suppliers will often have a tariff that suits your energy needs better than your current deal. In just a five minute phone call, you can save hundreds of pounds a year while staying with your existing supplier.

While you’re on the phone, ask your supplier if you can receive a discount by changing your paying habits; if you’re currently paying on receipt of bill, most energy providers will offer a substantial discount if you switch to direct debit or to managing your account online. People are often worried that swapping to one of these paying methods would reduce their ability to access personable customer service. In fact, most providers will still let you ask questions regarding your account and give meter readings over the phone, so you get the best of both worlds: significant energy savings with the same customer service.

Managing your energy account online does require an email address, which can put off those who are technology shy. If that’s the case, why not send your bills to the email address of a family member or friend and ask them to print off your bills for you? The difference between paper bills and managing your account online can be £100 a year – it’s worth giving it a look! Always double check with your provider before making any account changes.

Number 2:Use comparison websites such as uSwitch to compare deals from energy providers yourself. Sometimes switching tariffs isn’t enough to get the best deal – you may want to change energy provider. You will be asked to enter your postcode, existing provider, energy tariff and how much you are currently paying for gas and electricity each month. This process will take about 15 minutes, but within a few moments after searching you will be able to see all the best deals from across the entire energy market.

Number 3:Greenvision Energy include a free tariff check as standard on any installation. Thinking of making your whole home more energy efficient? We subscribe to the ‘whole house approach’ of energy saving and we can conduct a free home survey to assess which energy and water saving measures are best for your property, including insulation, energy efficient hot water cylinders and LED lighting.

We can also advise on how to maximise your budget by combining our funding and finance packages so that you can install more than one measure to reduce your home energy and water costs. We can also check if you’re eligible for benefits such as the Warm Home Discount and Winter Fuel Allowance. Check out our Money Advice pages for more information.

What is a standard tariff?

Sometimes referred to as an ‘evergreen’ tariff, this is your supplier’s ‘default’ tariff and is usually the most expensive one offered by the energy company. Over 50% of customers in the UK are on a Standard tariff, possibly because this is the tariff that you will default back to after any fixed rate deals or special offers have ended. The price of this tariff can go up and down with the market, so you’re never sure what you are going to be charged. You could even be subject to a ‘No Exit’ fee if you leave!

What is a fixed energy tariff?

A fixed energy tariff is one which offers guaranteed standing charges and unit rates over a fixed period of time. This tariff is a good option if you want peace of mind and are not planning on moving for a while. Although you won’t benefit from any price cuts while on a fixed tariff, the fixed prices that many suppliers now offer often work out much cheaper than being on a Standard variable tariff. Bear in mind that if you increase the amount of energy you use, the amount you pay will go up; fixed tariffs only guarantee the cost of the standing charge and the pence per kilowatt hour cost of gas or electricity.

Fixed rate tariffs are usually between 1 to 3 years, so it’s important that you look for a new tariff after your expiry date. Otherwise, you will revert back to a standard tariff and end up paying more for your energy. Even if you’re already on a fixed tariff, it may still be worth looking at switching, as the savings from switching can outweigh the cost of the exit fee.

What is a dual fuel tariff?

A duel fuel tariff provides gas and electricity from the same energy supplier. Energy providers usually offer discounts for using a dual fuel tariff, and this option often speeds up the process of tariff switching. Duel fuel tariffs also make managing your energy bills a lot easier as you are dealing with just one supplier.

What is an online energy tariff?

Some of the best energy deals are online tariffs as, in return for you managing your account via the internet, you’ll usually receive a discount to your gas or electricity. This involves sending meter readings online and receiving ‘paperless bills’: invoices sent as attachments to emails or available to download from your personal account area on the supplier's website. In most cases, you will still be able to contact your energy provider by phone to get information on your account and a friend or family member can receive emails on your behalf if you don’t have an email account.

What is an Economy 7 tariff?

With an Economy 7 tariff, you pay a different price for your electricity at different times of day. This can save you money as the electricity you use between 12.00am-7am costs a lot less than the electricity you use during the day - a bit like peak and off-peak phone calls. As you will pay more for day-time electricity, try to avoid running appliances that consume lots of energy between 7.00am and 12.00pm, such as a 2kwh panel heater. Instead, perhaps think about installing storage heaters; since storage heaters charge at night and then release their heat during the day, they’ll save you money as well as energy! We particularly recommend our range of Dimplex smart storage heaters as they are 27% cheaper to run than a standard storage heater, fully controllable and you can choose how long to charge them for, depending on your lifestyle, weather conditions and your pre-set times and preferred temperatures.

From standard tariffs to fixed rate deals, there are hundreds of Economy 7 options to choose from, so make sure you shop around!

What is green energy tariff?

A ‘green’ tariff can be one of two things: either the supplier will contribute to environmental schemes on your behalf or they will record the amount of energy you use and then generate the same amount from renewable sources. This tariff is a good option if you are concerned about the environmental impact of your gas and electricity use, but you should watch out as many green tariffs charge higher than average prices. However, green tariffs are not always more expensive and you can get a good deal by shopping around.

Energy Bill Guide

Typical Electricity Bill

  1. Your ACCOUNT NUMBER, sometimes called a CUSTOMER REFERENCE NUMBER, is unique to you and is used to identify your personal account details when you contact your supplier.
  2. ELECTRICITY SUPPLY NUMBER. This is your electricity supply number. It provides a unique identity reference number for your electricity meter.
  3. The CONTACT DETAILS of your electricity supplier including phone number and office opening hours.
  4. EMERGENCY CONTACT DETAILS to be used out-of-hours.
  5. The DATE your electricity bill was issued.
  6. The bill will be ADDRESSED to the person whose name appears on the account. You may wish to have more than one named person on the account in case of a change in circumstances.
  7. The PERIOD OF TIME you have been charged for the electricity you have used.
  8. The AMOUNT that was left on your bill from the previous payment. This could be a credit, a debit or a zero balance depending on how you pay.
  9. The PAYMENTS YOU HAVE MADE since the last bill.
  10. This is the TOTAL COST of the electricity you have used (or have been estimated to have used) for the billing period.
  11. Your NEW ACCOUNT BALANCE or AMOUNT OWEDwill take into account any existing credit you have on your account and will show as either a credit, a debit or a zero balance.
    • If you are a Direct Debit customer this will fluctuate throughout the year due to seasonality and the amount of electricity used.
    • If you pay each bill in full, as with standard quarterly customers, it will usually show a zero balance followed by the full amount owed for the current billing period.
  12. If you pay by DIRECT DEBIT you pay a fixed amount each month over a set period of time, usually a year. If these payments are too high and you are building up a large credit, or too low and you are building up a debt, your supplier will recalculate the amount you need to pay and will either increase or decrease your monthly payments to match your use.

Typical Electricity Bill

  1. PERSONAL PROJECTION is an estimate of your electricity use over a set period of time, usually a year. This helps your supplier set your payment plan if you are a direct debit customer, or can help people budget if they pay quarterly.
  2. Cheaper tariff options now have to be highlighted to you by your supplier. Some suppliers will even tell you of cheaper tariffs with other energy suppliers. You can use an accredited switching site to view the best deals in your area.
  3. Your PREVIOUS reading is the meter reading which is used as the starting point for this billing period.
  4. Your LATEST reading is the meter reading which is used as the end point for this billing period. It is used to generate your current bill.
  5. ESTIMATED or E readings are those supplied by your electricity supplier when they do not have an ACTUAL or ‘A’ reading supplied by either yourself or a company meter reader. Some suppliers may show readings you have provided as CUSTOMER, ‘C’ or YOUR reading. ESTIMATED readings are based on your previous use and average consumption levels.
  6. ELECTRICITY UNITS USED is the amount of electricity you have used during the set billing period. It is calculated by taking your PREVIOUS reading and subtracting it from the LATEST reading.
  7. Electricity is measured in kiloWatt hours (kWh). The kWh rate is the current amount you are paying for your electricity. You may be on a tariff that is FIXED and this will remain the same for the period of your contract, or you may be on a STANDARD tariff which means the cost of electricity will fluctuate depending on the market.
  8. The STANDING CHARGE is a fixed cost associated with providing your electricity supply such as meter reading, maintenance and the cost of keeping your home connected to the network and fees paid to other companies who operate and maintain parts of the electricity network.
  9. The CHARGE is the amount you need to pay, minus VAT which will be added to the total cost at a rate of 5%. If the VAT on your bill is more than 5% you may be being charged a commercial rate and you should contact your supplier.
  10. How you pay for your electricity and the amount you pay is called a TARIFF. There are many different tariffs to choose from offering different payment options, discounts and terms and conditions. It is worth asking your supplier if you are on the best tariff, or looking to see if there is a better tariff with a different supplier. There may be a cancellation fee if you switch tariffs or suppliers.
  11. Further information on how direct debit plans are calculated.
  12. Big energy suppliers have to offer their vulnerable customers extra services. They each have a Priority Services Register which offers free support to those with extra needs. Contact your supplier for further details.
