Wondrwall Group Reviews 

If I could give Leslie at Wondrwall a thousand stars, it still wouldn't be enough!

During my recent move, I encountered several frustrating technical issues, but Leslie completely turned the situation around. She went above and beyond to support me, tackling every problem with patience, dedication, and true expertise until everything was seamlessly resolved. She truly listened to my concerns and catered to every single detail, making what could have been a highly stressful settling-in process feel completely effortless.

Leslie’s exceptional customer service didn't just fix my technical problems—it left me feeling entirely elated and genuinely valued as a customer. Thank you again, Leslie, for making my moving experience so much better. You are an absolute superstar, and I cannot recommend your support highly enough!

Wondrwall have consistently overpromised and undelivered in their service to me. I completed my application for the battery subscription in late March and I still don't have a date for installation. Worth noting that my local DNO (SSEN) said that they did not receive a G99 application until late June which suggests to me that Wondrwall sat on my application for nearly 3 months. SSEN provided a quote to Wondrwall for connection on 1st September and Wondrwall have not responded to SSEN to accept that and/or contacted me for installation date. The product is obviously a great one, but they have massively underestimated the demand and appear unable to make the necessary changes that would allow them to deal with their backlog. I didn't want to write this review, but I've been left with no choice due to the poor communication and lack of responsiveness from the company.

I signed the order in May this year for subscription battery and since then I have had to chase for any update on my order (last call I was told October for installation but here we are with no confirmation or update on that) rather than any proactive communications. I understand the CEO video explainer, but it doesn't preclude communications to customers on their specific circumstances / order.

Further to my recent comments. I received a phone call from Jonathan who explained the current situation. The CEO has also just produced a video explaining the situation. Although the company are having initial problems with the roll out of their PowrPlan I think this is due to their excellent product. They seem to be addressing the huge demand and I hope they now keep their customers up to date on the progress of the role out. I think this product is a no brainer for anyone who has an EV tariff.

When I saw this service i thought it is a great idea to be able to rent a battery for my solar panels instead of paying for it upfront.
The staff at Wondrwall were extremely helpful in explaining the technicalities of the product and the service in a way I could easily understand, and responded quickly to any queries I raised. Overall it’s been a great experience and I’d strongly recommend them.

Everyone I dealt with was really super helpful and knowledgeable. James was the person I dealt with most and he was excellent and persisted until we'd cracked my problem. Thank you.

After learning about the new strategy to support homeowners in purchasing home energy storage, I was immediately impressed by Wondrwall’s Powrplan offering. I submitted my home’s technical details and photos within a few days of the official launch.
The ability to store excess solar generation without any upfront cost made the solution particularly appealing. Additionally, the inclusion of free installation, DNO application, and a full 10-year package covering support, maintenance, and warranty provides real confidence in what is ultimately a long-term investment.

I had a number of technical questions, particularly as I was exploring the option of installing the system in my detached garage alongside my existing solar and inverter setup. I appreciate that the team has been extremely busy with enquiries, so I fully understand the response times. I would like to extend my sincere thanks to Mark, Toby, Ali, and James for their detailed and patient support throughout—I’m sure my volume of questions was no small task.

I would also like to thank the wider team for honouring the original Powrplan pricing from the time of my application. With my contract now signed and submitted for DNO approval, I look forward to the next stages.

Finally, I wish Wondrwall every success going forward and hope to see the platform continue to evolve, particularly in line with advancements in technology and dynamic energy pricing.

Kind regards,
Craig Sutherland

I recently moved into a property which had Wondrwall appliances installed. I was struggling to pair the appliances with my phone. Got in touch with technical support and James Davidson did a fantastic job of explaining to me step by step how to resolve the issue. He even called me after work hours to ensure it was resolved before the weekend. Great company and very professional staff

Fantastic, professional service

Absolutely brilliant, resolved in minutes. Thank you 😊

Very, very, very helpful and very, very, very able

I installed an additional heater to the system, and needed technical support to interface the new panel.
Thanks again for the quick support and phone call to talk me through and resolving the problem.
Many thanks Paul

A good response from James on Saturday
Thank you

So far very good. Tech support replied promptly, clarified a number of queries I had, and helped me understand what is needed so that my setup is ‘Wondrwall ready’ for their engineers to proceed with an install.
I am proceeding now with the order.

Always respond quickly and always helpful

I don't know how, but these guys always answer any questions I may have straight away.

I've had some problems with wonderwall over the years. But now the app and all the appliances work very well thanks to Toby and the team's help and guidance. Toby was quick to respond and kindly gave me a call to help me set things up when I had issues. Thank you very much!

I honestly can’t praise Wondrwall enough. From day one, their customer service, IT support, and engineers have gone above and beyond to support and maintain my new Echo House energy system.

No matter the time or the day, there is always a real person at the end of the phone — someone who listens, reassures, and actually takes ownership of any issue. That level of personal support is incredibly rare these days and makes all the difference.

What I appreciate most is that they completely understand that not everyone is an IT or electronics whizz (certainly not me!). They explain everything clearly, patiently, and in plain language that I can genuinely understand — never rushed, never condescending.

It’s reassuring to know the system is backed by a team who truly care, are highly knowledgeable, and are always there when needed. Outstanding service from a company that clearly puts people first.

Highly recommended.
