I have had no problems with Ovo after the initial transition from a very poor energy company, the coop energy. the Ovo team were prompt to address concerns and have had no problems at all with billing, online management, and have been able to reduce my direct debit to reduce the surplus created from initial estimate direct debit. very happy with Ovo and plan to stay.

I've just switched from NPower a few months back and really like their service. Its a billion times better than NPower (never again) - they tell you everything you need to know, their support is fast and helpful and their prices are pretty good. I like them.

Looking forward to switching over it seemed like it was going to be easy. This is a smaller company growing extremely FAST and like most have hiccups. We had some hiccups by OVO was very good at trying to make us happy. In fact several hiccups but they made me feel valuable and important when calling and did listen being apologetic each time quite genuinely. If it wasn't for this and the unbiased metre engenier praising this company I would have left. In the end they got everything working perfect with over one month FREE electricity. Now we have fab new meter. Waiting times at most uk call centres isnt always good but I work for a company who is helping ovo to so know they have this in hand although this will take time.

I am always able to speak to a representative, who I can understand. Polite and helpful, seems good value up to now, although I feel that they could be a little more 'upfront' with their customers. I was well over £100 in credit, and asked for a refund, my next direct debit payment due in two weeks. Was informed that could only refund excess over my DD monthly payment, and that it could take a staggering 14 days to reach my bank. WHY? my DD payments can leave my bank in 24 hours, so why this massive delay in refunds ??????

Switched from British Gas to OVO in February. Have had no issues - their mobile app is great for updating meter readings and website extremely clear and easy to use. You can change your direct debit amount easily. Have definitely been the best energy company I've had to deal with compared to British Gas (who were decent, but expensive), nPower and EDF (both of whom were horrendous).

Despite all the poor reviews on this site, the Which report (http://www.which.co.uk/switch/news/2011/01/best-and-worst-energy-companies-revealed-243074) shows that OVO was one of the best providers. Having spent many years being unsatisfied with British Gas, I'm very pleased to have changed to OVO and will be saving over £400 per year on my dual fuel.

After being with British Gas for 27 years i decided to switch, so i went on a comparison site and found Ovo were the cheapest. Had no problems with switch over and the Ovo website is good.They actually reply to my e mails and seem very helpful. I seem to be on course to save around £400 a year on my Dual fuel bill.As i am on the flexible payment option i can get a certain amount refunded each month when i go into credit, also i can reduce my next monthly Direct Debit payment.Up to now i am happy with Ovo.

Ovo were a bit disorganised to start with when I first went on supply, but other than that very good service. All queries answered. Easy bills to understand. If you contact them, you are answered straight away and very rarely get put in a queue and the staff are very polite. Online system allows you to take control of your direct debits and how much you pay. Also allows you to apply for a refund on your credit balance (although does not offer a full refund as it is their interst you stay in credit which makes sense). So far so good. Would recommend.

Easy way to deal with them, I get prompt replies, able to agree direct debit amount each other, getting % interest back my account and somehow friendly.

I switched to OVO after the other companies were forever increasing my direct debit to cover my 'increased useage'. I use an electricity meter so I know this is a lie and it is just to cover their increased wages. I found OVO to be cheap and chearful in a good way. there is no Nectar points or clubcard points to increase the cost of my power used. They do however give 3% intrest on credit balances. They do their bit for the rainforest by buying a space of rainforest per customer. This does two things. It saves that part from being cut down. And it also ofsets my personal usage of CO2. I have had my DD increased once but that was only a pound a month. I recommended OVO to my dad but he mentioned all the bad reviews online so I thought that I would come and write a positive review. Each time I submit a reading it is lower than the esimated reading. I can not imagine how much money I have saved by not using any of the big names
