Section A

About This Agreement

1. Standard agreement. (a) Section A of this agreement contains the standard terms of our agreement with you. These standard terms and prices only apply to single, domestic premises with an individual meter.(b) This agreement is based on the information you have given to us, either directly or through an agent. You acknowledge that when entering this agreement you are responsible for the property, live at the property and are duly authorised to enter into this agreement. If we cannot check any important information about you or your meter or the information available is not up to date, or the information you have provided is significantly inaccurate or we cannot supply a customer with your type of meter, we may terminate this agreement. We may also terminate this agreement if your meter or metering arrangements are not suitable for the tariff or payment option you have chosen or offer you an alternative payment option. If you don't object or if you choose not to cancel your contract, we will assume your acceptance of the alternative offered. (c) If we provide you with incorrect prices in error we reserve the right to change your prices by notifying you of the correct prices. (d) We can refuse to supply premises if they are split into more than one home whether or not each home has an individual meter.

2. Commodity supply. If we supply both your gas and electricity, we do so under separate agreements, although you may receive a combined bill (which will show your gas and electricity charges separately) at our discretion.

3. (i) When this agreement starts. (a) Each separate agreement for gas or electricity starts from the date that you sign it, accept it on the phone, or enrol online. If none of these apply to you, the agreement starts when you start receiving supply of gas or electricity. (b) If we are taking over from your current supplier, we must complete the transfer within 22 days from the date you entered into the agreement, or where a cancellation period applies, within 22 days after the end of the cancellation period. (c) However, we do not have to complete your transfer within the period set out above if: (i) you ask for the transfer to take place at a later date; (ii) you inform us that you no longer want to change suppliers; (iii) your current supplier has objected to the transfer; (iv) after taking all reasonable steps, we still do not have all the information we need from you to complete the transfer; or (v) we are prevented from completing the transfer due to any other reason which is beyond our control. (d) If the transfer has been delayed for one of the reasons set out at Section 3(c) (iii), (iv) or (v) above, once that reason no longer applies we will complete the transfer within 21days of the date that the reason for the delay no longer applied. (e) You agree to your current supplier giving us all your relevant details to help with your transfer and where applicable transferring to us the right to collect any debt you owe to that supplier and passing over all relevant account information. (ii) Renewals.   If your agreement is for a fixed term, then we may only extend the term of your agreement for a further fixed term period (with or without any changes to other terms and conditions), that is no longer than your existing fixed term period, if no earlier than 49 days and no later than 42 days before the fixed term period of your agreement is due to end, we give you a copy of the applicable regulated renewal notice, which will be a separate document and will be sent separate from any other documents. You will be under no obligation to accept the proposed renewal of your fixed term agreement, we will seek your agreement in writing, and you should consider your options. If you do not accept your renewal option and you do not switch to another supplier, then we will move you to our cheapest standard tariff.

4. Changing your mind.  You can cancel this agreement within 14 days from the date you signed or accepted it. To cancel, simply write to us with your agreement number, saying you want to cancel or use the cancellation form provided to you.

5. Our charges. (a) You agree to pay our charges based on the tariff that applies to you. You can find details of all applicable charges and tariffs, and the basis on which we calculated the same, on our website We will add VAT and other required taxes, as applicable. (b) We may also charge you (at our discretion)  for all reasonable costs (including legal fees and administrative costs) that we incur in trying to collect payments from you.

6. Price changes. (a) Unless your product is a fixed rate product, we may change our prices, discounts or the way we charge forgas and electricity. If we increase our prices or make any other change to the terms of this agreement which disadvantage you (for example, we reduce our discounts), we will tell you about the changes at least 30 days before they begin to apply. If you do not accept the changes, you may terminate this agreement within the 30 days notice period so long as we also receive notice from another supplier, after you terminate this agreement, no later than 20 working days after (but not Including) the date on which the changes have effect and notifying us that the new supplier will begin to supply your home within a reasonable period of time. If you owe us money and we object to you transferring your supply to another supplier, if you still want to leave us you must pay us any money you owe within 30 working days of us telling you that we object to the transfer. If you don't pay the money you owe within 30 working days, the price changes will apply and we reserve all rights to object to the transfer. (b) When we change prices, we'll estimate the meter reading on the date the price change takes place. We'll use this reading to calculate your charges at the old prices up to the date we change the price.

7. Discounts. (a) We may offer you a discount tailored as specified to you. You will only be entitled to a discount if you meet the conditions which apply to the discount.

8. Meter readings. (a) You must give us meter readings at least every six months. This will help us to make sure your bills are as accurate as possible. We may ask you to provide more frequent meter readings depending on your method of payment. (b) When we produce your bill or statement, we will, if possible, use a meter reading that we or you have taken (this is an 'actual meter reading'). If no actual meter reading is available, we will produce a reasonable estimate of usage at your property (which may be based either on your previous usage or industry averages). You agree to pay the estimated amount or give us an actual meter reading. We will send a new bill based on this actual meter reading (unless you agree otherwise) or, if no bill is due at that time, we will use this actual meter reading when we work out your next bill. (c) If you purchase both gas and electricity from us, and you want to update your energy usage, you must give us both meter readings, even if only your gas or your electricity usage has been estimated. If we do not receive meter readings for both fuels, the fuel without an actual meter reading will be estimated when we next send you a bill. (d) If your premises shares an unmetered supply of commodity with other premises (for example, electricity used in shared parts of a building divided into flats), we may estimate the amount of commodity used and charge you an appropriate share. (e) If, in our reasonable opinion, the meter reading you provide is not accurate, we will not use it, but we will try to contact you to get a new meter reading and will inform you of the fact that we have not used the reading provided by you. (f) If, for any reason, your meter does not register any gas or electricity used, you agree to pay the amount that we reasonably estimate you have used.

9. Costs for unaccepted payments. We may charge to recover any reasonable costs we have to pay if we have to return a cheque to you, or a direct debit is rejected because there is not enough money in your account, or you send us a post-dated cheque or if we have to pay costs to give you copies of cheques or bills.

10. Costs related to your meter. We may charge you to recover any of the following reasonable costs (Please see our website for details): (a) Changing your meter if you ask us to, or when you become our customer if your type of meter is not one that we can support on our system. (b) Moving your meter. (c) Repairing or replacing a damaged meter or meter seals.(d) Disconnecting or reconnecting your meter. (e) Carrying out a meter accuracy test if you ask for this and we do not find a fault with the meter. (f) Getting a warrant to enter your home if you refuse to let us in. (g) Costs related to your breach of this agreement.

11. Costs related to your prepayment meter. We may charge to recover the following reasonable costs: (a) Replacing a prepayment device and the reasonable costs of getting it to you. (b) Visits to your premises by our agents because you have run out of credit due to a problem with your prepayment meter and/or prepayment device. (c) Fitting a prepayment meter to avoid disconnecting your supply. (d) Changing a prepayment meter to a credit meter if you ask us to make the change. (e)The reasonable costs of repairing or replacing the meter. (f) Replacing a smart prepayment meter with a traditional prepayment meter where you are switching to us from another supplier and request such meter change.


12. When payment is due. Payment is due on the date shown on your bill. If there is a genuine dispute about any amount, you must pay the amount you agree you owe. When we have settled the matter, if necessary we will adjust the bill. If you are entering into this agreement together with other people (such as your partner), you are each jointly and severally responsible for paying all amounts due. We may keep and offset any money we owe you to reduce any debt you owe us or any of our affiliates. You may not be able to switch providers if you owe us money.

13. Payment plans. If you cannot pay your bill, we may offer you an instalment plan and/or ask for a security deposit instead of fitting a prepayment meter. While you still owe us money under your instalment plan, you may not be able to change suppliers. If you move, you will have to pay us the full amount you still owe under the instalment plan, unless you ask us to transfer the amount over to your new address and you continue to take your supply from us. If you fail to make any payment due under the instalment plan, the plan will automatically end and we may install a prepayment meter on the property. We may change your payment method upon 7 working days' notice if you have not paid your bill within 28 days of the due date, and/or have failed to comply with terms and conditions relating to a payment method. We will advise you of the proposed change, reason for and effect of the change and the price that you will pay in the future.

14. Security deposits. We may ask you to pay a reasonable amount by way of a deposit as security against payment for your commodity if you don't have a prepayment meter. If we ask you for a deposit and you do not pay it, we reserve the right to terminate this agreement.

About Your Meter

15. Damage to the meter. You must take reasonable care to make sure that the meter is not interfered with or damaged. If you notice any damage to your meter, or if you suspect that someone has interfered with your meter, you must tell us as soon as possible.

16. Position of the meter. Our meter readers must have easy access to read, install, test, inspect, repair, disconnect, reconnect, remove or replace your meter when necessary. The meter must also be in a safe, secure and weather proof position. If it is not, or is not easy to get at, you must allow us to move the meter.

17. Prepayment meters. You may ask us for a prepayment meter. We will install one for you if we can. A prepayment meter may be more expensive than other ways to pay for energy. We may ask you to pay for your commodity through a prepayment meter on our prepayment terms. We may do this if you failed our credit checks, a prepayment meter is already installed, we have reason to believe that someone has tampered with an existing meter, or you owe us money.

18. Smart meters. If you agree to have a smart meter installed, we will arrange a convenient appointment for the installation. If we or our agent are not let into your property for the appointment, we may charge you the costs of that visit, unless you gave us at least 48 hours' notice of cancellation. If you had a smart meter installed by your previous supplier we will treat it as a traditional credit meter until such time as we notify you that we are able to utilise its smart functionality. If the smart meter is operating in prepayment mode and you wish to continue on a prepayment tariff then we may replace your smart prepayment meter with a traditional prepayment meter.

19. Who owns your meter? If you have chosen to fit your own meter and any related metering equipment (which must meet certain standards and be fitted in accordance with industry procedures otherwise it may be removed by us or our agent) then you own the meter. Otherwise, a service provider owns your meter and any related equipment supplied with it, even when it is installed at your property. If a service provider transfers your meter to another service provider, you agree that both you and the new service provider will continue to have the same rights and obligations as before. You will be responsible for all the pipes, wiring and equipment on your side of the property beyond the meter installed at your premises and we are not responsible for those nor for their safety. You are also responsible for the meter housing.

Ending This Agreement

20. Moving. (a) You must give us at least two (2) working days' notice before you move from the property. You must also give us details of your new address and your final meter readings so that we can send you your final bill. If you have given us the correct notice, your agreement with us will end on the date you move out of the property. If you fail to give us the correct notice, your agreement will end either two working days after you tell us that you have moved, or when someone else takes over the supply, whichever occurs first. (b) Until your agreement ends, you will still be responsible for paying for any commodity used at the property. If you delay in telling us about your move, you may have to pay for any energy used during the period when nobody else was registered as taking the supply. If you do not give us your new address and we have to pay costs to find you, we may add these costs to your final bill.

21. Your right to end this agreement.  Your agreement with us will end if and when: (a) you change suppliers and the new supplier starts to supply your home; (b) we start to supply you under a new agreement; (c) we lose our licence to supply commodity; or (d) the supply is cut off because it is no longer needed. Until then, this agreement will continue to apply and you must pay for all commodity supplied hereunder until the end of the term of this agreement. If you have a fixed term agreement, you may: (a) take steps to facilitate changing to any other supplier (but not complete the process of changing supplier) at any time without having to pay a termination fee; (b) unless you have already entered into a new fixed term agreement with us, you are entitled to switch to any other supplier without having to pay a termination fee at any time during or after the period that is 49 days before the date the fixed term period of your agreement is due to end; (c) you are not required to give any form of notice to terminate a fixed term agreement or to switch supplies, a termination fee may apply.

22. Transferring to a new supplier. (a) If you want to transfer to a new supplier, we can only prevent the transfer if: (i) you tell us that you have not entered into a contract with another supplier and you want us to prevent the transfer; (ii) you owe us money; (iii) your proposed new supplier agrees that the transfer was a mistake; or (iv) your proposed new supplier does not apply to transfer all the related meters at the property on the same day. (b)We will take all reasonable steps to send you your final bill within six weeks of the transfer to your new supplier being completed. (c) There is no administrative charge for transferring to a new supplier, and we will do everything reasonably possible to help with the transfer. You may have to pay a termination fee if it applies to your agreement and/or tariff.

23. Our right to end this agreement. We may end this agreement for any or no reason by giving you 30 days' notice in writing. We may end the agreement immediately in the following circumstances: (a) If you have failed to pay for your commodity, cannot pay your debts, or have failed a credit check, and: (i) you have refused to pay in instalments, have a prepayment meter, or pay a security deposit; or (ii) it is not possible for us to fit your property with a prepayment meter. (b) If you breach this agreement. (c) If we lose our licence to supply gas or electricity, as applicable.

24. Transferring your details to a new supplier. We may give your new supplier any relevant details to help with the transfer. If you owe us money, we may object to your transfer, or sell the debt to your new supplier for them to collect. We will give them full details of the debt. Ofgem can withdraw our supply licence in certain circumstances. To make sure you do not lose supply, Ofgem may give a 'last resort supply direction' to another supplier to take over the supply from us. If this happens, your agreement with us would end on the date the Ofgem direction takes effect.

25. Cutting off your commodity. We have the right to cut off your commodity in certain situations only. We may do this in the following circumstances: (a) If you have failed to pay for your commodity, or cannot pay your debts; and you have refused our offer of paying in instalments, through a prepayment meter, or to pay a security deposit; (ii) it is not possible for us to fit a prepayment meter; (iii) If it is not reasonable for us to supply you and we give you 7 days' notice that we are ending this agreement and cutting off your commodity. (b) If we supply you with both gas and electricity, we do so under two separate agreements. We will not cut off both your gas and electricity unless this is for a reason which applies to both gas and electricity. For example, if you have failed to pay for your electricity, but have paid for your gas, we will not cut off your gas supply for nonpayment. (c) If you are having difficulty paying, we will offer to fit a prepayment meter before we cut off your commodity. If necessary, and if you refuse us access to your property, to avoid having to cut you off we may apply for a warrant to fit a prepayment meter without your permission. Or, if you have a type of meter that we can convert from a credit setting to a prepayment setting, we may do that instead. You must then pay for commodity at our prepayment rates, which may be more expensive than your current rates. We may also set the meter to collect any money you owe us.


26.  We may cut off your supply if we have to do so by law or in an emergency, or as a result of other circumstances beyond our control. We may also cut off your gas supply if supplying gas to your home might put the public in danger and we have taken all reasonable steps to prevent that danger from arising. If we supply you with gas, we and the gas transporter who operates the network through which the gas is supplied to you also have the right to tell you to restrict or stop your use of gas if we or the gas transporter have to do so by law or in an emergency. You must then follow our instructions.

27. In an emergency, you must allow us, and anyone we authorise, safe access to your meter at any time.


28. Limitation of liability. (a) Nothing in this agreement removes our legal liability for death or personal injury caused by our negligence. If you suffer any loss or damage, our responsibility to you will be limited to the lesser of six times the average monthly payment due from you for the affected property and £1,000,000 or, if there are a number of connected events that cause you loss, our responsibility will be limited to £1,000,000 in total for these events. This agreement does not affect any rights you have by law, including your rights under the Consumer Protection Act 1987. (b)Except for liability for death or personal injury, as set out above, we are not legally responsible under this agreement for any losses that are not our fault, or that we could not have reasonably expected when we entered into this agreement, or any special, punitive, exemplary, indirect, or consequential damages, or losses or damages for lost revenue or lost profits, whether foreseeable or not, arising out of, or in connection with, this agreement.

29. Business use. (a) If you have used commodity supplied to the premises for business purposes, and we have to pay a higher rate of VAT or any other extra taxes (for example, climate change levy), you must pay these taxes in full unless you meet the HM Revenue & Customs requirements that allow you to provide us with 'exemption certificates' which cover the taxes due. (b) If you are a business customer and we have supplied you as a residential customer by mistake, these terms and conditions will not apply. We will continue to supply you under our 'deemed business terms' unless you sign up to an agreed set of business terms with us or you change to a different supplier. (Our deemed business terms are the terms that a business customer is supplied under by our Hudson Energy division. The deemed business terms may be more expensive than our other business terms.)

30. Assignment and subcontractors. We may assign or transfer any of our rights under this agreement, including this agreement, to any other person or company. We may assign or transfer any of our responsibilities to any other licensed supplier of commodity. We will tell you as soon as we reasonably can if we transfer any rights or responsibilities. We may also subcontract anything we have agreed to do under this agreement. However, we will still be responsible for our subcontractors.

31. Governing law. In any dispute, the law of England and Wales applies to this agreement if your home or property is in England or Wales, and Scottish law applies to this agreement if your home or property is in Scotland.

32. Circumstances beyond our control. You and we will not be responsible for failing to keep to the terms of this agreement (other than any failure to pay) if that failure is caused directly by circumstances beyond your or our reasonable control, or any actions required by law.

33. Service levels and complaints.  Please see our website or write to us at: Green Star Energy, Elder House 3rd Floor, 586-592 Elder Gate, Milton Keynes, MK9 1LR

Electricity Only

40. About this part of the agreement. By signing this agreement for an electricity supply or accepting it by phone or online, you are entering into two contracts. They are with us, to supply electricity to your home; and your local network operator, to distribute electricity across a network so that we can supply electricity to you. Your supplier is acting on behalf of your network operator to make an agreement with you. The agreement is that you and your network operator both accept the national terms of connection (NTC) and agree to keep to its conditions. This will happen from the time that you enter into this agreement and it affects your legal rights. The NTC is a legal agreement. It sets out rights and duties in relation to the connection at which your network operator delivers electricity to, or accepts electricity from, your home or business. If you want a copy of the NTC or have any questions about it, please write to: Energy Networks Association, 6th Floor, Dean Bradley House, 52 Horseferry Road, London SW1P 2AF. Phone: 020 7706 5100, or see the website at

41. About the electricity supply. The local network operator is responsible for the characteristics of your electricity supply. The electricity delivered to your home through the network will normally be at one of the voltages shown below. It will have the following frequency, number of phases and margins of variation associated with it:

i. connection voltage and permitted variations: at 400/230, 460/230 and 230 volts, plus 10% or minus 6%.

ii. number of phases of supply: at 400/230 volts, three; at 460/230 volts and 230 volts, one.

iii. frequency of supply and permitted variations: at all voltage levels, 50 hertz, plus or minus 1%.

If you need more explanation about these figures, please call your local electricity network operator who may be listed in your phone book under electricity distributors.

42. This Guarantee is offered by all banks and building societies that accept instructions to pay Direct Debits. If there are any changes to the amount, date or frequency of your Direct Debit, Green Star Energy will notify you 10 working days in advance of your account being debited or as otherwise agreed. If you request Green Star Energy to collect a payment, confirmation of the amount and date will be given to you at the time of the request. If an error is made in the payment of your Direct Debit, by Green Star Energy or your bank or building society, you are entitled to a full and immediate refund of the amount paid from your bank or building society. If you receive a refund you are not entitled to, you must pay it back when Green Star Energy asks you to. You can cancel a Direct Debit at any time by simply contacting your bank or building society. Written confirmation may be required. Please also notify us.

Terms and Conditions for Paperless Bills

43. To sign up for paperless bills, a valid email address must be provided and Green Star Energy informed of any changes to this email address. Only the Green Star  Energy account holder or their authorised representative can set up paperless bills. Any suspected unauthorised use should be reported immediately. Failure to advise Green Star Energy of changes to your email address may result in the paperless bills service being stopped. If problems with your email account prevent the delivery of your bill notification email, we may stop paperless bills and reintroduce normal paper bills via the post this may invalidate a discount you may be receiving. In order to maintain accurate records, you must validate the registered email address when requested to do so. Failure to respond to this confirmation request may result in the paperless bills being stopped which may invalidate a discount you may be receiving. Occasionally there may be additional information on your bill relating to payment amounts or dates. It is your responsibility to log in to view your bill and note the changes. Other notifications may continue to be sent in the post. Only those bills produced since paperless bills were set up, that you would normally have received through the post, will be viewable online. If you move, you will need to notify Green Star  Energy in the normal way, by either phoning or completing a change of address notification form on the website. You can set your new address up for paperless bills as soon as you receive your account number.

Changes to your direct debit payment amount will continue to be communicated via your bill or, in some instances, by post. This email notification constitutes 'advance notice' on the assumption that you will view your bill. It is therefore your responsibility to open all emails from us and view your bill in a timely manner, in order to be aware of changes to your payment amount.
