Who are Symbio Energy?

Symbio Energy are based in Watford and are a relatively new business, having only started supplying energy in March 2019.

They pride themselves on supplying 100% renewable electricity and gas, and being the cheapest electricity supplier in the UK.

What tariffs do Symbio Energy offer?

Symbio Energy offer a range of fixed rate tariffs. Each of these tariffs have a £25 exit fee. There is also a variable rate tariff which has not exit fee.

There are no specific tariffs for electric vehicle owners and Symbio Energy does not offer a ‘feed-in’ tariff. Pre-payment tariffs are not available.

How do Symbio Energy compare price?

Symbio Energy claim that they have been the cheapest electricity provider in the UK since March 2019 and that they can save customers up to £600 per year compared to the Big Six energy suppliers.

They say that they can do this by using technology and only accepting payment by monthly direct debit to keep their costs down.

To back this claim up, they offer a price guarantee policy. If a customer can find a cheaper tariff elsewhere, Symbio Energy will match the tariff and give the customer a £10 Amazon voucher.

The reviewers on TrustPilot agree that Symbio Energy’s pricing is competitive.

What do other Symbio Energy reviews say?

Because Symbio Energy are a relatively new company with only a small number of customers, they have yet to be reviewed by Which? or Citizen’s Advice as neither organisation has sufficient data to give them a rating.

There are 430 reviews on TrustPilot where they are rated as poor with only 2.7 out of five stars. 50% of the TrustPilot reviewers rate the company as bad. The main complaint is poor customer service. However, many of the reviewers comment that Symbio Power’s prices are cheap.

How green is Symbio’s energy?

Symbio Electricity comes from 100% renewable sources. In addition, They own a number of green energy patents covering energy generation, storage and distribution.

Their gas comes from renewable sources such as farm waste.

They say that they are “on a mission to end climate change”.

What is Symbio Energy’s customer service like?

Symbio Energy doesn’t have a live chat feature on its website although customers can message them via their app. Alternatively, they can be contacted via the phone, email or post.

No information is available in terms of how quickly they answer the phone, how many complaints they receive and how quickly they deal with any complaints.

However, many of Symbio Energy’s reviewers on TrustPilot are highly critical of the customer service. Symbio’s response to criticism has been to accuse a number of the negative reviewers of cyber bullying.

What is Symbio Energy’s website/app like?

Symbio Energy’s website is poor. It isn’t obvious where to find the information that you need and quite a lot of information appears to be missing from it. The lack of a search feature does not help. There is no live chat feature, either.

There is an My Symbio, a web-based portal, but all that allows you to do is update your personal details, submit meter readings and view your previous 12 months energy consumption figures. You cannot make a payment via My Symbio.

It is a similar story with Symbio Energy’s app. This is available for Android and Apple’s iOS devices. At Google’s Play Store it only achieves 2.2 out of five stars. Apple’s App Store it yet to rate the app because nobody has downloaded it to date.

What billing options are available?

Symbio Energy prefer payment is by monthly direct debit. Symbio Energy say this helps them to keep costs low and this means that they can pass on those cost savings to their customers via lower bills.

The first bill is sent a month after the switch has taken place and the payment is taken four weeks later. The initial bills are based on estimated energy consumption. Future bills are adjusted to take actual consumption into account.

Customers can opt for a Seasonal Fixed Direct Debit. Under this scheme, the direct debits are adjusted to take into account the fact that customers use more energy during the winter months. This means that they are not overpaying during the summer months and do not go into arrears during the winter months.

Customers can also pay by bank transfer or by sending a cheque in the post. Pre-payment accounts are not available.
