Good communications

Good communications, good website and being able to see your energy consumption and costs updated daily is a big advantage. Smart metre does all the work and submits readings direct. The ability to review your direct debit and adjust on line is excellent.

Easy to deal with.

I've been with OVO for years. Never had a problem, billing or anything else. Pricing was always competitive, although this years new contract was a bit of a shock. I'm not going to change from them - Better the devil you know than the devil you don't!

Nov '21 will be 10 years with OVO Energy. I initially chose them on price and the fact that they paid an interest reward (until Ofgem said it was too confusing). I have stayed for the service (i.e. good website & not screwing up), their low-carbon credentials (I'd be happy with nuclear power too) and easy ability to track usage. I only wish that they would have a something that shows how much my energy usage & carbon footprint has changed since I became a customer.

My OVO

I have been with OVO for four years and don’t have any complaints about their service. One thing went wrong with my meter and an adviser talked me through how to fix it. All the advisers I have spoken to have been helpful. My tariff has worked well through the years and I have been told when there was a cheaper one. Very happy with OVO.

Why did I renew my contract with OVO?

Why did I renew my contract with OVO? Reasonable prices - but mainly because it's less hassle - and I like things simple!

The reason I stayed is because ovo has not been mentioned as one of the energy companies struggling and the fact I am paid interest in my credit balance at a better rate than any savings accounts I hold with my bank.

Glad to be back with OVO

Glad to be back with OVO. Had moved to avro what a mistake that was, just switched 2 weeks before Avros collapse. I liked the deals OVO were able to offer at that time - being able to fix energy prices for 2 years. Not having to even think about switching for 2 years. Love being able to manage my account online, really missed being able to adjust direct debit online without having bother Customer services. Replies to customer emails are prompt and within the 5 day turnaround period. Love the green energy ethos of this company, the planting of trees in the uk to help us all reach net zero carbon emissions sooner. There is no getting away from the fact that my energy contract is a lot more expensive this year (and for so many others out there.) But I now know what is critically important in choosing an energy supplier and that is the ability to contact customer service and then receiving a prompt helpful reply back. Indeed I am prepared to pay that bit extra for good customer service, especially after the past few awful months at AVRO. I think OVOs deal was competitive and I liked the fact that I didn't have to agree to a smart meter installation unlike many of the deals being offered by several of their competitors.

Fear made me stay

Fear made me stay. Fear of being unable to change to a new supplier who in all. Likelihood will go bust. The price rise is awful.

A good experience so far

Choosing your energy supplier is not easy during these difficult times. We have been with OVO for 3 years and we renewed for a further 2 years before the current crisis. We have not experienced any difficulties during our time with OVO and have found staff helpful on the rare occasions we have had to contact them. We read our meters each month and the billing system has not created any problems for us. The utility comparison systems are not without their difficulties for the layperson but as far as we can ascertain the rates are competitive.

Important information 

1 Renewable electricity is cleaner than traditional electricity sources because it produces less carbon emissions and pollution. The renewable electricity we sell is backed by renewable certificates (Renewable Energy Guarantee of Origin certificates (REGOs)). See here for details on REGO certificates and how these work.

2 By switching to OVO Energy you could reduce your carbon footprint by up to 1 tonne of carbon per year. This is based on the carbon emissions caused in the production and consumption of the 100% renewable electricity OVO provides as standard, compared to the emissions caused by the production and consumption of UK grid average electricity. Average UK household energy consumption figures were sourced from BEIS (2019). The carbon emissions factors were calculated by the Carbon Trust.

4 Saving based on the estimated annual cost for a non-economy-7, dual-fuel, high user (4300 kWhs elec. and 17000 kWhs gas) paying monthly in advance by Direct Debit. Comparisons made against the Ofgem published tariff cap for a customer on a standard variable or default tariff that comes into effect on 01/04/2021, applied to the same high user consumption values. Savings are an estimate only and your actual costs will vary according to your region and usage. All rates correct as of 05/08/2021.

5 An independent study has shown that installing and correctly using a tadoº Smart Thermostat can reduce your energy use from heating by up to 31%. The study found that the tadoº device can reduce heating energy requirements by 14-26% through controlling the heat source (e.g. boiler or heat pump). You could also save another 7% by turning down the heating based on the weather forecast, depending on the window sizes. If the window surfaces are relatively large, the energy saving will be greater. Reducing energy use from heating will result in less carbon being emitted, which can help make your home greener. Savings are an estimate only and your actual savings will vary depending on your energy use and the changes you make to your energy habits.

6 Enjoy even greener energy with OVO Beyond in comparison with our standard OVO plans. In addition to 100% renewable electricity as available with our standard plans, OVO Beyond reduces your yearly carbon emissions from the energy used in your home that is supplied by OVO to net zero by providing 100% carbon-neutral gas (15% green gas and 85% offset) and offsetting all associated lifecycle carbon emissions involved in the production and consumption of your electricity & gas, you will also get 5 trees per year in UK schools and communities and other green benefits. The renewable electricity we sell is backed by renewable certificates (Renewable Energy Guarantee of Origin certificates (REGOs)). See here for details on Renewable Energy Guarantee of Origin certificates and how these work. The green gas we sell is backed via renewable certificates (Renewable Gas Guarantees of Origin (RGGOs)). See here for details on Renewable Gas Guarantees of Origin and how these work. We offset the remaining emissions by supporting UN REDD+ carbon reduction projects that are certified to the Verified Carbon Standard or the Gold StandardSee here for more information on how we restore nature and protect rainforests with our offsetting programmes.

7 We were the first mainstream supplier to remove coal and nuclear from our fuel mix - find out more www.ovoenergy.com/about

8  Powering and heating your home can make up 28% of your carbon footprint. This is an average amount and excludes emissions from things that you cannot directly control such as supporting the NHS, defence, government bodies, etc.

9 The trees we're planning to plant this year will absorb around 54,000 tonnes of carbon in the next decade. To find out how this figure is calculated, read our blog: https://www.ovoenergy.com/blog/green/trees-natures-carbon-eating-machines.html
