What our customers say
”I was thinking about getting solar for my home and stumbled upon www.solarplanet.uk. The site's super easy to get, breaking down all the solar jargon. After reading up for a bit, I filled out their quote form. The next day, I got calls and emails from three solar companies in South Wales. Chatted with all of them, got quotes, and went ahead with one. The whole experience was smooth, and all the companies seemed top-notch. Big thumbs up!

”Running a business, those rising energy bills were starting to pinch. So, we thought, 'Why not try solar?' A quick online search led us to Solar Planet. Filling out their quote form was a breeze, and guess what! The very next day, three solar experts from Bristol gave us a shout. They were all super helpful and knew their stuff. Picking one was tough since they all had great offers. And a big relief! They all had this MCS accreditation – a real peace of mind with all those dodgy stories you hear these days.

”It couldn't have been easier! Initially, we were scratching our heads trying to find a trustworthy company. Then, thanks to a quick Google search by my husband, we landed on Solar Planet. He filled out their quote form, and the next day, three different solar installers rang us up. We've been over the moon with both the installation and the ongoing support. They guided us through the whole process from installation to helping us find the best energy provider for solar power.
