This company is dire! It is utterly useless in terms of customer service. It sends me bills and threats even though I have never ever had dealings with the, Steer clear. They are appalling. Useless. Totally incompetent. They are a joke.

Green Star/Hudson Energy is an appalling company. Steer well clear. They merged my electricity and gas accounts despite my written instructions not to. Eventually they demerged them but assigned the gas account number to the electricity account. I was given a new account number for my gas. Thankfully I left them in May. They now say I owe £355 for gas despite my having paid £365 on the new gas account number. They are so incompetent that they can't reconcile the two accounts and are sending fatuous letters headed notice of intended action and threatening me with a debt collection agency. I have emailed a complaint although I have no confidence in their ability to resolve the issue. As a back up I have written to Joanne Thornton, managing director at Hudson Energy. I can see that I may need to call in the Energy Ombudsman on this one. A rating of -5 stars if it were possible.

This is the worst energy supplier I have ever had to deal with. Switched supplier in February and 8 months later after dozens of e-mails, calls and involving the ombudsman I am still waiting for the £300.00 credit on my account to be returned.

Wish I had read some of the reviews on this company before switching to them, but have never had difficulties with previous suppliers and never dreamt what a nightmare to deal with a bad one would be - after my experience and reading that of others it is beyond me how this company is still in business.

Worst energy provider I have ever had to deal with.

- Customer service is horrific. Not only are you on hold for ages your are sure to receive different information regarding he same issue depending on who you speak to and they never respond to your queries.

- Apparently the electricity meter was faulty. Even though the previous two readings were the same Green star didnt feel the need to make this into and issue until I wanted to close my account

- Its taken months of phone calls and emails to them directly which was then followed by a complaint to the ombudsman to get this resolved with only a £75 compensation.

I will never use Green Star again and could not recommend it to anyone.
Avoid at all cost!!!!

Have been dealing with Green Star Energy on behalf of my Daughter. What a nightmare. You may think that they are ok when you join but the first time you contact them with a problem the trouble begins. Customer Service, they do not know the meaning of the words. I have finally extracated my Daughter from their clutches with the help of the Energy Ombudsman who,after investigation,ordered them to pay compensation together with a letter of apology which they did at the END of the month given to them. AVOID at all costs if you value your sanity. Pity lowest is one star rating.

I put in Gas reading wrong on App? Rang straight away about my mistake. They said no worries they'd sort it, but they didnt. They kept asking about yhe app reading on the Gas and I kept explaining about my error, despite me giving them my opening balance and recieving it officially from SSE.

Its over a year and Ive still not a proper gas bill. Ive given readings on several occasions and theyve told me, it will be sorted with the other department. They have contacted SSE again to coroberate the reading, and said it would take a month and its not. One error and a year's worth of jumping through hoops to no effect. So im changing, something tells me they'll be able to produce a bill now im leaving.

My father died two weeks ago and only when looking through his bills found he had joined them over a year ago and they set his direct debit at £38 when in fact he was using more like £85. They never increased his direct debit to cover this like most reputable energy companies do. Have now found out he racked up a bill of £925. No way can I afford to pay off his debt as on universal credit myself. Disgusting incompetent company.

This company is completely useless. I have been with them since July 2017,everything went well paying by direct debit until I moved house. I have been paying £50 a month, live on my own and work away from home two weeks out of every four so very little power used. I have now received numerous emails saying that I owe them £1,217.90!!!! Can't get through to customer service as they are constantly "upgrading" their computers. The one time I managed to speak to someone I was cut off before I even started explaining the problem. I have now been threatened with debt collection. I have sent them a lengthy email but no response. Thank goodness I cancelled my direct debit otherwise that amount would have been taken. Looks like next move is ombudsman or legal action.

Why should they expect me to continue to pay monthly direct debits when they cannot produce proper bills that can be checked.

They told me they were cheaper than Scottish energy. NO, they were not. They also did not tell me they were quarterly billing only. So thinking they were taking the money monthly, they served me a bill after three months, and was higher than I paid Scottish energy and they are not that cheap either. I have been paying the bill off slowly. Meanwhile, they are not taking for the current bills! They called me and admitted they had lied when I emailed my complaint in strong words. She stated that the agent should not have lied to me about being cheaper when they were not, and that I would not be charged the exit fee either and the block to the new provider would be lifted. My mobile automatically records all calls, so I have her recorded. Now they have emailed me to say they won't let me go until the bill I am paying off is paid, and they want the exit fee. I said I would continue to pay £6.00 a month until they were paid even when I moved to another supplier, and that is also recorded. Looks like I will have to go down the legal route.

WARNING do not use this company as you're energy supplier. Green star energy residential trading name of Hudson energy. All was fine until I wanted to leave green star energy, I had built up a credit on my account, WARNING they will do everything possible not to give you you're money back, will not issue final account, will not accept you're readings on day of switch, will not accept your new providers readings on there first account. I even offered to email details they said no. Won't let you speak to any one higher or management to resolve the problem. They have cost me time, money and hassle. I have instructed the energy/ombudsman services to try and recover my money. I will post this review everyday on sites until my money is returned as we are not just talking a few quid it's a few hundred pounds I am owed back of MY money. So stay clear of GREEN STAR ENERGY.

Have received numerous bills relating to a year ago addressed to "The Occupier", suggesting that they don't even know who they were doing business with. Despite calling them a number of times to tell them that they have not been the provider since I have owned the property (6 months ago) and asking them to stop, they haven't. Instead they have seen fit to send somebody round to my property and then post a handwritten letter, telling me that I need to call them to set up an account (fat chance). After calling them yet again and asking to speak to a manager, "David" (assuming that was actually his name) thought it better to cut me off, rather than put me through to someone to speak with. I wouldn't use this lot if they paid for the energy on my behalf.

It is absolutely horrible. I signed up to Greenstar half a year ago with a payment via direct debit. For a couple of months, I did not notice any payments for my bills. A couple of months later I received a letter stating that my case was passed to Debt collection agency. When trying to contact them to sort out the issue, I was told that I need to contact Debt collection agency and that they are not going to deal with this matter. On numeral occasions, I have tried to contact them with no response. I also had problems with my online account as they never set it up for me, and when trying to get a login, a Greenstar advisor said they would solve the issue, but they did not. I have switched to another provider, but I have no idea what to do now as I still want to pay the debt but have no idea how.

Please do not switch to these clowns.

They have achieved a level of incompetence that puts them head and shoulders above the rest.

Sending emails out in the name of my deceased Father for 10 months after his death despite being asked to change it countless times.

Complaints handlers deciding to close cases despite there being no resolution. Account managers being unable to understand that I cannot provide final bill details from another company as they are midway through an investigation into how a 2 bedroom terrace house is billed for £3,500 of gas in a two month period. Repeatedly asking for information from the other company that I do not have and cannot get, failing to take notice of emails requesting contact from them to discuss the case - being threatened with legal action if I dont pay the bill despite it being in dispute - I really can't afford to take the risk of my credit rating being ruined by these morons so I've had to settle for what I think is twice the amount that is due - it goes on and on.

NO matter how cheap they claim to be compared to your current provider do not switch to these - happy enough to take your money but totally useless at dealing with problems.

I joined Green star through a scheme by my council and I have saved money with them. I switched from the Co-op and my bills went down about 15%.

They aren't very good with people wanting to pay fortnightly or weekly via Paypoint and I'm a bit put off when they keep pushing the direct Debit scheme which I don't want.

They are okay and I'd advise other people to consider them.

I initiated a change over approx 5 weeks ago and within 24 hours had changed my mind. I informed them by email within 24 hours thatI did not wish to proceed. They contacted me twice to confirm the cancellation.
They then tell me they haven't acted within the 14 day cooling off period and they had erroneously taken over my gas!
"Don't worry it will all be resolved"

I took no action believing it would sort out.
Then I discover they have still enacted the direct debit and withdrawn nearly £200 from my bank.
My old payment was £111.00 per month. The difference I suspect is because they I think have charged me a leaving penalty for NOT informing them within 14 days. I had, within 24 hours!
They now tell me they are still supplying my gas but not electric and this will take 6+ weeks to resolve.
I cancelled the direct debit arrangement they had set up today (despite my cancelling the contract) and Green Star have today sent me a thinly veiled threatening email regarding non payment, affecting my credit rating etc etc.

I've made a formal complaint and I am getting nowhere. They have even told me that 'my complaint is now resolved' - Ha ha.
So how many mistakes have they made - I've lost count.

I've changed suppliers many times and never had any problem. This lot are entirely dreadful. Just don't be tempted at all.!

Got them to admit that they mislead us into leaving our previous company but they refuse to repay the full amount it has cost us to move away. First off they ended up being around 18% more expensive which they agreed they would honour for the first six months of new package (yay them).

They agreed they would pay for the £60 early settlement fee that is put in place to keep you in their hiked price deals. So I asked them to repay the £60 it cost me to move to their more expensive deal from the previous supplier who I would have stayed with if they had not mislead us, not a chance. They are refusing point blank to move on this.

They are using underhanded methods to get your business and then not giving a damn when they leave you out of pocket. STAY AWAY FROM THEM!

Green Star are the most unprofessional company we have ever had the misfortune of dealing with and we would advise everyone to give them a wide birth unless you want to be stitched up, insulted by they call centre staff and even accused of cancelling direct debits mandates when we hadn't.

Their administration can only be summed up as totally incompetent as they either don't communicate with you or send you multiple identical letters on the same day.

This company gives utility companies a bad name and should be closed down.

DO NOT TOUCH THEM unless you want problems.

Even the omnibudsman cannot control these cowboys so what chance do you think you have when it goes horribly wrong?

My brother switched my 83-year-old aunt onto a dual fuel fixed tariff with Green Star Energy as it estimated her monthly D/D based on usage would be approx 35/month. However, a year on and another switch attempt and Green Star say they will not allow her to be switched as she has an outstanding bill of over 1,000!! It seems her monthly d/d have not covered the amount she was using, but instead of contacting her when the bill started mounting, or increasing her d/d automatically (which my energy suppliers have always done), they allowed a year to pass so she now faces a bill she cannot possibly pay in 1 amount! It's been extremely difficult getting hold of customer service, too. I would not use GS!

They don't reply to customer service emails, as soon as you switch they get in contact.The new bill format is more confusing than the earlier simpler format. They lie about 12 months fixed rate contracts, my contract ended up over 13 months hence the customer service email they never replied to. There were cheaper tariffs but when I tried to switch something always went wrong. The annual total usage estimate was way to high in my case.There are cheaper tariffs from other suppliers.
