What customers say

Based on genuine customer reviews

Warmer Energy is described by customers as handling projects from survey to completion in a joined-up way, whether the job involves air source heat pumps, solar panels, battery storage or cavity wall work. Reviewers repeatedly mention the thoroughness of the initial survey, with one household noting how much detail was gathered before anything was proposed, and quotes and documentation supplied promptly by Hugh. Communication comes up often: Solomon is named for keeping customers informed and for checking on finished work, while Sam and Tom drew praise for returning to help connect a system to a new router after installation.

The installation teams, including Mike, Eddy and Brian, are credited with working hard, staying late to finish and taking care around an elderly resident. Tidiness and clear explanation of funding, grants and hybrid systems feature in accounts, and several describe the difference in bills from the first day. Where a cylinder developed manufacturing faults, the problems were resolved without fuss, and subsequent adjustments to improve the property's energy rating were completed to schedule.

Our solar panels were installed on Thursday May 28th. The service provided by Warmer Energy from survey to installation has been excellent. Solomon kept in touch with us throughout the process and provided the required documentation. Ten days after the installation we had to contend with a new router. Nothing was too much trouble. Tom and Sam came to our rescue when we struggled to connect the WiFi to the system. We are impressed with the performance of our panels. Even on dull, rainy days our battery has powered up nicely. We would both highly recommend Warmer Energy. We have been impressed with their customer service, after care support and the quality of the product.

I've just had solar panels, a Sigenergy gateway, battery system and EV charger installed by Warmer Energy. Every person I dealt with from the business was polite, helpful and competent and the pricing is very competitive. I asked a lot of technical questions in my initial enquiry which were answered promptly and well. The installation and commissioning took 1 day and was to a high standard which I am more than happy with, and I now have a great system installed saving me money on my energy bills.

Solar panels and storage battery installation. Overall, very satisfied. I would highly recommend this company. The process right from the start was quite efficient and pleasant. Initial quote provided by Hugh promptly, via email, unlike most other companies which will annoy the customer with repeated and unnecessary phone calls. This was followed by a survey to asses our home requirements. The surveyors (Sam and Tom) were very nice and knowledgeable, they were able to answer all our questions effectively. Installation was delayed, due to equipment taking longer than expected to clear customs; at this stage there was some lack of communication by admin staff, we had to contact the company for clarification. But, we were rewarded by a very welcome upgrade to the latest battery technology, at no change to the price. Organisation and time management of the installation process was excellent. The scaffolders arrived on time and were very good and quick. Then the electricians team arrived the following day lead by Tom. For the most part, performance was excellent. A team of a few young men arrived first in the morning, they clearly had very limited experience in the technology being installed. They also rushed to make a few drill holes in the wall/ patio which were unnecessary, but when Tom arrived a bit later he was able to put everything right and the installation went smoothly. The roofers arrived later on the same day to install the solar panels and the whole job was finished in one day. The scaffolders came back a couple of days later and took the scaffolding down in no time! All in all, a well orchestrated effort, with wich we are very pleased . Suggestion - the group of young electricians could do with some more training, particularly with regads to new tech. I am sure they have a brilliant future ahead...

I have tried to contact Warmer but put on hold for 15 minutes when a message comes on too say leave your name and phone number with a message I have done that quite a few times and no reply, I am sitting in a very cold house with very high electric bill I have complained on numerous occasions but no one wants to address the situation, I have found that warmer do not communicate very well at all I would love someone to respond so I can get this resolved .
