OVO Energy have backed your void electricity supply with UK REGO certificates, so it's certified as 100% renewable; with no additional charges or changes to tariffs.

This means that while your property is supplied by OVO Energy, you have the potential to achieve a carbon footprint reduction of up to 80 kgCO2 from your electricity consumption within the void period (per property). That's about the same as the emissions from driving around 300 miles in a diesel car.

In addition, if tenants wish to continue on a greener path, there's a new OVO Energy AddOn called Go Green that they can take advantage of - although this does come at a small premium. More info here: https://sse.co.uk/energy/go-green
