It was a couple of years ago because I didn’t try with my last supplier so maybe things have changed now. Worst was British Gas as they posted the smart meter to me, then sent an engineer. He knew as soon as he came in it wasn’t an option but couldn’t take the meter back so I was left tripping over it until I finally binned in.
I have emailed customer services at Bulb directly but got no answer hence asking on here.
I also went through the FAQs and couldn’t find an answer to these questions though did see something about needing 2’ around it. All ours are in the same room and are much closer together than that.
