Green Network Energy Business Energy Profile: Tariffs & Reviews

Green Network Energy is one of the UK’s fastest-growing independent energy suppliers. They serve micro, small and medium-sized businesses with gas and electricity, with 100% renewable electricity and gas available. 

They are an Italian company, founded in 2003 by entrepreneurs Piero Saulli and Sabrina Corbo. Their move into the UK market was in response to Ofgem’s investigative action into competition in the energy market, which was dominated by the big 6. 

Green Network Energy wanted to shake things up with a customer-orientated, ethical alternative to the big 6. They are a small supplier compared to the likes of EDF and E.ON, but this makes their service more personal. Their prices are competitive, and they also do a Smart Export Guarantee tariff for businesses. 

Key features:

  • 100% green electricity and gas
  • For micro, small and medium businesses
  • Contract lengths from 1 or 2 years
  • Fixed and variable tariffs
  • Smart Export Guarantee (SEG) available 

Green Network Energy Core Services

Green Network Energy supplies electricity and gas to micro-businesses and SMEs. The only limitation to becoming a customer is your annual consumption, with Green Network Energy only supplying businesses who consume up to 100,000 kWh a year. 

They offer a few different tariffs, including fixed and variable electricity and gas tariffs, with fixed tariffs fixable up to 2 years.

They also offer businesses a Smart Export Guarantee tariff, which pays a rate of 3.5p/kWh of electricity exported. 

The company is making strides towards being 100% green and currently offers 100% green electricity and gas to eligible businesses. Their traditional energy plans also source over 50% of electricity from renewable sources.

Green Network Energy Deemed Rates

You will pay deemed rates if you move into new premises and there is an existing energy supply from Green Network Energy. It means there is no contract in place, so your energy is priced at ‘deemed rates’ until you take out a contract.

Deemed rates are significantly more expensive than contract rates, so we recommend switching to a contract as soon as possible. 

Green Network Energy’s deemed rates are as follows:

Electricity deemed rates

  • Standing charge – 50p/day 
  • Unit rate – 20p/kWh

Gas deemed rates

  • Standing charge – 100 p/day
