Good boiler install, clear process

I had a Worcester Bosch combi boiler installed last month. The online quote was straightforward, giving me a fixed price. The installation team arrived on time and finished up in about a day and a half. They were tidy and explained the new controls clearly. My old boiler was removed without fuss. Everything worked fine after they left. Customer support quickly answered a question I had about the boiler's warranty registration a few days later.

New boiler, mostly satisfied

I got a new Vaillant boiler through Glow Green. The initial quote was competitive, especially with the 0% finance option. Delivery for the installation crew was prompt. The installation itself was smooth, though they did leave a bit of dust behind that I had to clean up. The boiler works well, very quiet. It's a solid service overall, but that small cleanup detail kept it from being a perfect 5-star experience.

Hey has anyone used Glow Green? Thinking about getting a new boiler for my place in New York, and wondering what the total timeline for installation looks like after I get a quote.

I just did this last month! From the quote to actually having the boiler in, it was about a week and a half. They're pretty quick once you confirm everything.

Yeah, my experience was similar. The actual installation day was just one day, pretty painless. The longest part was probably picking the boiler and getting the survey done beforehand. They won't install in the US though, they're a UK company. You'd need to find someone local.
