Customer Reviews
So easy, really impressed!
anyone else used BOXT? i needed a new gas boiler and their fixed price quote was super clear, came with a Hive thermostat too which was a nice bonus. no messing about with referral codes either, just applied it at checkout. way better than trying to compare British Gas or Heatable.
Super easy boiler swap!
Anyone else used Boxt for a new boiler? I was looking at a new Worcester Bosch, and their fixed-price quote was really competitive, especially as it included a smart thermostat and magnetic system filters. I was wondering if they'd remove the old boiler too, and yep, that was all part of the service. Didn't even need to mess about with referral codes until the very end which was handy. Definitely glad I went with them over some of the others like British Gas or WarmZilla.
Reliable AC install again
This was my second time using Boxt, previously for a boiler. This time I got a multi-split air conditioning system. Just like the last order, everything was handled efficiently. The fixed price quoted was exactly what I paid, and the installation team was professional. It's why I keep coming back for these types of home projects.
Quick boiler install
Had a new Worcester Bosch boiler installed by Boxt. The process was straightforward online. Installers arrived on time and finished the job in about half a day. No issues.
New EV charger was easy
Needed an electric vehicle charger at home. Went with Boxt after looking around. The online survey part was actually pretty simple to do. They sent someone out pretty quick, took about 3 hours for the install. The guy was friendly enough. Everything works fine. Felt like a good deal overall, just kinda happened without much fuss.
