Consistent service, as usual

Used Heatable again for a gas boiler replacement in my rental property. This is my third time using them, and the process was smooth just like the others. The fixed price guarantee is always a relief, no surprises. Installation took a day, as expected. They've been reliable for me over the years.

Good value, minor snag

I had a combi boiler installed last month. The online quote was straightforward, and the price was competitive compared to other places I checked. The installation itself went well, the engineer was professional and tidy. It took 3 days for them to schedule me, which wasn't next-day but still reasonable. My only minor issue was that the smart thermostat they included, a Hive Active Heating, took an extra day to get fully connected with my home network after the engineer left. I figured it out, but it would've been nice if that was all squared away at install.

Hey, anyone know how legit these Heatable discounts are? Like, I see stuff about referrals and seasonal sales, but can I combine a couple of those, or is it usually just one deal at a time?

B Brett 2 months ago

From what I remember when I got my boiler, the discounts are usually built into the quote. Like, you might get a seasonal deal, but you can also punch in a referral code during checkout for a little extra off. Don't think you can stack a bunch of random codes though.

J Julia Vargas 2 months ago

Yeah, pretty much what the other person said. They do fixed pricing, so the big discounts are already in there for like specific brands or seasonal stuff. The referral bonus is separate, and you use that at checkout. I used one and it worked fine.

Thinking about getting a new boiler from these guys, but I'm in Chicago. Do they even service the US or is this just a UK thing?

L Laura P. 2 months ago

Nah, pretty sure Heatable is UK only. I looked into them last year for a boiler install and everything pointed to them being based there. You'd probably need a local company.

S Sam Whitfield 2 months ago

Yeah, I think you're outta luck if you're in the US. Their website, everything about them, just screams UK. Try someone like Boxt, but check if they're in your area.
