We had 24 solar panels and three storage batteries fitted by Smart Energi Ltd. of Wrexham. They quoted promptly, answered all our questions fully, arrived to fit the equipment on the promised day and then cleaned up after themselves. Since then, 8/9 months ago, we have had just one query, which they answered immediately and helpfully. The boss, Tim, is good news and they are probably the best workmen we have ever dealt with. We have no hesitation in recommending them to other potential users.
