A Cornish firm providing renewable energy solutions has been awarded the highest of accolades by its customers.

ZLC Energy, based in Penryn and St Austell, was independently assessed by an industry body that monitors quality standards. The IWA provides insurance to businesses working in the home improvement sector. Each member is vetted and continually monitored through feedback from customers on every job they carry out.

Following a recent survey, ZLC Energy was found to have a 100 per cent customer service satisfaction rating. Owner and managing director, Mark Smith, said: “The greatest commendation is the one provided by our clients. We have a great team that works incredibly hard to provide outstanding customer service and it is great to know we’re getting it right.”

Customers were asked questions about their installations of renewable energy products, carried out by ZLC Energy. The 100 per cent rating led to the IWA issuing a certificate of merit to the firm, which will be valid until next spring.

Mark added: “This is external validation of the effort we put into doing a good job. It was a lovely surprise as we didn’t know the survey was being carried out until we were notified about the award.”

ZLC Energy fitted solar panels on Katrina Walker’s house in Penryn. She said: “I couldn’t recommend ZLC highly enough. They were so helpful, even printing off the documents we needed to arrange our tariffs as our printer wasn’t working.

“They helped us along every step of the way and were very supportive. The installation was carried out quickly and cleanly, regardless of the weather as it was raining non-stop when we had the panels installed.”
