Avoid. Used this company as they advertise an association with IKEA whom I trusted and I'm an anti fracking campaigner of some years. So trusted company alliance with renewable energy 👍. This company... See more

I am so please that hopefully I can…
I am so please that hopefully I can switch to another dual energy company, as Ollie gave me the go ahead to do just that for So Energy. But unfortunately that supply to the converted house is not clearly labelled and insofar that we cannot change until the MPAN and MPRN are supplied as the meters in question are not clearly labelled I cannot fully switch energy suppliers. But the custimer service from Big Clean Switch was so helpful and the website was user-friendly. Well done Big Clean Switch.
Great online support
Very knowledgeable and helpful online chat that gave me all the info i needed to switch my energy provider easily. Highly recommend
Supplied extra background information
Very helpful in giving us background information on an energy company. This had not been included in details of tariff by another advice/review website which we had previously found reliable for other financial matters. We reconsidered our choice as a result. Online Help very prompt and effective when we used it (during week day afternoon)

Rebecca answered my question about smart meters fully and quickly, so I signed up immediately which was also easy. I like the way they increase the dd for the cold 6 months and reduce it for the warmer months. It's like a Spring Summer bonus!

Big Clean Switch is top notch
Big Clean Switch is top notch! They made it super easy for me to switch. Being too busy (as we all are)...I was a bit hesitant to take the time to make the switch, but the website is user friendly, very clear and the choices of energy suppliers quickly identified with their unique offerings. Before I knew it, I had switched and now feel great about it.
Nothing but an easy and pleasant…
Nothing but an easy and pleasant experience with them. Affordable tariffs and the customer service is amazing. Really pleased with my switch.
Win Win
Win Win. I was keen to put my money where my environmental principles were, and the Big Clean Switch helped me do that - without spending too much of my money! Since switching to Octopus via the BCS, I've now stayed with Octopus but on an even greener tariff. I've nothing but praise for both companies.
Saving money with energy from 100% renewable sources definitely deserves a 5 star rating.
It was incredibly easy to switch; there was no inconvenience or issues in any way and I didn't need to do anything. I changed from British Gas to Octopus Energy and my monthly DD reduced by over 50% and after winter I still had credit in my account, which was refunded to me. I recommended Octopus to my parents and their switch went off without a hitch and our accounts were both credited with £50. Saving money with energy from 100% renewable sources definitely deserves a 5 star rating.
Go green and cheap!
Switching to a greener, cheaper and extremely efficient supplier was very easy. I recommend this service.
Super easy process
Super easy process! Switched with no fuss to a cheaper but, more importantly, greener supplier. Great to talk to real people too!
Really excellent service
Really excellent service. We switched and saved about £30 a month. It's so easy and gives you the confidence to take control.
Recommend!
I switched using my energy provider using the BCS platform and saved a significant amount of money - £70per month! Plus it was quick, easy and transparent. Great way to cut back on my carbon footprint.
