Ovo excellent

I had been with ovo at my previous address, always had great service. Was easy getting a smart meter and online account simple even for someone not great at technology! Moved couple of weeks ago, new property edf energy, 3 weeks of trying sort out smart meter, still not done. 3 weeks of trying to pay by direct debit, still not done. Contacted them took 3 days for a reply. Contacted ovo, reply within 1 hour, thats why im switching to ovo!

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
