SmartestEnergy reviews, prices and tariffs

Although SmartestEnergy has been around since the turn of the century, it’s never offered domestic energy and so may not be a household name. But it does specialise in energy supply for SMEs, with a focus on renewables and tech that can help businesses cut their energy usage and costs. 

Who is SmartestEnergy? 

SmartestEnergy began life in 2001 as an aggregator of independent generation projects. This meant that it was in the business of bringing together providers who would be too small to participate in the markets individually.  

A wholly owned subsidiary of the Marubeni corporation – a huge Japanese trading and investment business with interests in everything from fashion to telecoms to energy – Smartest Energy is keen to promote net zero carbon emissions among businesses.

The Business Division of Smartest Energy supplies gas and electricity to SMEs. It also provides businesses with the products and tools they need to hit net zero targets, including smart meters and a web analyser service to help business owners better understand their energy consumption. What services does SmartestEnergy offer? 

SmartestEnergy provides gas and electricity to small and medium-sized enterprises (SMEs).  

If you’re moving business premises, you can switch to SmartestEnergy. If your new business property needs a new connection, you’ll need to arrange this with your local Distribution Network Operator (DNO).  

Once you’ve sorted your supply, you’ll get a new MPRN for your gas meter, and new MPAN, KVA and meter phase type for your electricity supply. When you have these details, you can switch to Smartest Energy. 

SmartestEnergy also offers business energy smart meters to all customers. There’s also the option to manage your account online using the SmartWeb Online service. 

What tariffs and rates does SmartestEnergy offer? 

SmartestEnergy offers a range of gas and electricity tariffs to suit the needs of small businesses in all industries. 

  • SmartFix – This offers businesses the chance to lock in rates for one, two, three, or five years to help protect against future price rises.  
  • SmartTracker – A variable rate, three-year tariff that fixes prices for the first 12 months before reviewing costs against market prices every 12 months for the final two years. 
  • SmartPay – If your business uses a prepay meter, this fixes prices for up to three years to save up to 40% against competitor variable tariffs. 

Both SmartFix and SmartPay tariffs have a monthly fixed Direct Debit repayment plan to help you budget your business finances. SmartPay can be topped up online via SmartWeb, by phone, or via Direct Debit 

The rates and tariff type you’re offered when you switch to SmartestEnergy will depend upon your business and its current circumstances. Your contract will have a minimum period of supply, which could be up to five years, during which time you won’t be able to switch suppliers during this time.  

You can compare deals once your contract enters its switching window, which can be up to six months before your contract’s end date. Customers that renew with Bionic six months before their deal finishes could save you up to 20% compared to leaving it later.
