Core services, offering & fees

For Business

Firstly, like most business energy suppliers, Smartest Energy does not offer an estimated quote on their website to show you how much your bill might cost. However, this is only because every company requires it’s own bespoke quote. Due to the various factors that go into your energy bill.

This includes things such as the size of your business, your building’s location, how many staff you have and your consumption habits.

They do offer potential customers a brief look at their products which you can see below.

  • FlexiBase: Their fully flexible product gives you direct access to the open market, which allows you to manage your purchasing strategy to take advantage of market prices
  • Group FlexiBase: Do you have a multi-site business? With this option, you can group all of your sites into a single contract to get the benefits of their flexible products across your businesses portfolio
  • FlexiBase Dual Meter: Group all of your half-hourly and non-half hourly metered premises into one contract
  • EnviroPass: This unique electricity product passes through Government Taxes and Levies at the published rates, so you don’t need to pay more than you have to for your energy

Renewable Options

There are also renewable options that are all certificate backed so you know your power is 100% renewable.

  • Renewable Standard: 100% renewable energy from a variety of sources such as solar, hydro, wind and biomass
  • Natural Renewable: 100% renewable energy generated solely from wind, water or solar
  • Specific Renewable: 100% renewable energy generated from a particular source

Each customer of the renewable energy options will receive an annual energy label that will show you your carbon emissions and your fuel mix.

As the government expects certain larger businesses to submit information about their carbon emissions on a yearly basis, this option can help you stay within your responsibilities with the law.

For Generators

For those that are developing a new renewable energy generation project, SmartestEnergy claims that their experienced team can help you make the process easier to navigate.

  • FlexiPPA: FlexiPPA allows you to take advantage of the wholesale market with an active approach. This means having the flexibility to fix blocks of power volume on multiple occasions.
  • PPAPlus: This option is best for generators that are looking to make a secure revenue stream. Over a more extended period, with a guaranteed outcome regardless of the market.
