Testimonials

Happy Customers

The guys at Callidus were all fantastic. We had lots of questions before we had our solar power system installed, and all our many emails were answered very efficiently. The on site team did a really tidy job, and went through how we would use the system. We were very apprehensive about having an off grid system, and had different companies come to quote for the job. We went with Callidus because of the whole package that they offered, which includes their after sales help. We are very happy with the set up and it fulfils all that we asked for, very happy bunnies.

Maxine Heard

We live off grid in Cumbria and wanted to upgrade our electricity supply. We contacted Callidus and they were very happy to work with us. With excellent two way communication they designed the perfect system for us which is easily expandable if we should need it in the future. They were happy to design the system and supply us the parts for us to install ourselves. They programmed the system and were on the end of the phone to help with installation and getting the system up and running. Their after sales service is excellent. It has improved our quality of life no end.

Jack Beach

Fantastic customer service! Such incredibly helpful staff. Can’t rate them highly enough. Highly recommend this company. So helpful and really fast service. I spoke with Chris and Dave at a time when other staff where out and they went above and beyond to help.

Isobel Nancarrow

The entire team at Callidus, from the top to the bottom, are amazing. Knowledge, support, passion to place the customer and their needs at the centre of the process, throughout all phases. Clear explanations with realistic expectations; no over inflated figures to close out a deal. I am so satisfied with their approach that I have already completed an expansion of my system; NOT because it didn’t perform as promised, but in fact we are generating more than expected so have increased the battery storage!!

Marcus Rowe

I have just had an off grid solar system fitted by Steve and his team. It has been a completely stress free experience. Everyone was so professional, helpful and obliging, kind and friendly. I would recommend Callidus to anyone.
