Solarplicity promises ‘simply lower energy bills’. Find out if Solarplicity delivers on this and whether it’s the right energy firm for you.

Solarplicity, formerly called LoCO2, says it makes it easy to get cheaper energy bills, greener energy and deal with its friendly, caring staff.

It promises that its prices will always be lower than the Big Six energy companies and doesn’t charge exit fees on its tariff.

Solarplicity also offers 100% renewable electricity tariffs - it says the energy is generated from biofuels, wind, hydropower and solar power.

You can’t currently switch to Solarplicity because it is banned from taking on new customers by energy regulator Ofgem. This is owing to its poor customer service and switching processes. Read on to find out more, and what Solarplicity's customers think. Or compare gas and electricity prices to see if you can get a good-value energy deal with another firm.

Solarplicity customer score

Solarplicity was the lowest-ranked energy firm in our latest survey, which includes 30 energy companies. 

Its overall customer score was eight percentage points less than the next lowest-scoring. It was 36 percentage points behind the top-scorer, Octopus Energy.

Solarplicity was the only company to score just one star for its customer service online and on the phone, complaints handling, and its efforts to help customers understand and reduce their energy use. In fact, Solarplicity is the only company to get a one-star rating at all.

Which? verdict on Solarplicity

This is the first year we’ve had enough responses from Solarplicity customers to include it in our survey – and it’s the worst-rated supplier.

Half of its customers rated phone and online customer service either poor or very poor. Three quarters told us that it’s poor or very poor at dealing with complaints.

Plus it resolved only 14% of complaints within 48 hours in the first three months of 2018. The best firms for complaints-handling resolve 90% or more in this time.

Based on our survey results, Solarplicity needs to do more if it wants to impress its customers:

  • 58% of Solarplicity's customers said they had a problem with it in the past two years
  • 25% is the average across all companies.

Most commonly, customers said their problems were with customer service or the firm's website.

Customers were most positive about it being value for money; it scored three stars out of five for this, which is reasonable but not outstanding. The best firms are rated five stars by their customers.

Perhaps customers see value for money as its best aspect because it has offered some cheap deals over the past year. However, its standard tariff, which you’re moved onto if you do nothing when your deal ends, has been one of the priciest at times.

Two of Solarplicity’s energy deals come with energy-saving LED light bulbs. Its smart fixed tariff gives customers a £25 discount for having smart meters installed.

Though customers didn’t rate its overall phone or online customer service well, it was fast to answer the phone and to respond to emails in our snapshot undercover investigation into energy companies' waiting times in September 2018.

Pros: Offers some cheap deals

Cons: Customers rate its customer service and complaints handling poorly

Solarplicity in the news


February: Solarplicity was banned from taking on new customers for three months from 22 February. Ofgem said it must improve its poor customer service and switching process before being allowed to accept new customers again.

It is also banned from increasing direct debit payments for customers who are in vulnerable situations.

Ofgem will monitor its progress. If Solarplicity doesn’t improve, ultimately it could lose its license to sell gas and electricity.
