Second time these guys have knocked on my door with regards to selling a lease system for solar panels, which if you have electricity bills of +£80 per month, it could begin to make financial sense. I’d note that they take a lot of details up front such as name, address, dob, tel, and they want photos of your energy statement. There are workarounds for this as ultimately that gives them 75% of your ID. I didn’t let them take full image pics of statements… financials fine, but not the whole image to prevent fraud. Gave an alias name and a false dob. They need name to know who they’re talking to and the dob is required because they need to ensure any lease/loan of solar panels are paid off by your 80th birthday. They also want an email address to send appointment details too. They called me within 5 mins and I talked through and decided it wasn’t for me. They weren’t pushy, but there seems to be a lot of info gathered up front - i’d just suggest treading with caution to protect your identity. With that said, they have a website, there were 3 guys knocking on doors so looks legit as an operation and the caller was polite and informative. I asked them to remove all record of me based upon not going forward as is my legal right, which they confirmed they would. Hope this info helps someone
