How BOXT works

You answer a few questions about your home and send a few photos.


You choose a package that's tailored for you and choose an install date.


Their professional engineers will carry out the installation hassle and mess free.


What happens on the day?

What time will they arrive?

You can have a chat with your installer online and find out more about them on their profile page. They’ll walk you through what they’ll do, how they’ll do it, and keep you informed along the way.
Your installer will arrive at the time you have agreed. If you buy a boiler online by 3pm, you could get it fitted the next day and all work is usually carried out the same day. So you can relax and leave it to the experts.

What qualifications have they got? 

Every single one of BOXT’s installers are Gas Safe registered. They have the right skills, tools and experience for the job. 

Will they leave any mess?

Your installer will lay dust sheets out wherever they work to make sure your home is 100% protected. Once the job is done and dusted, your installer will take away any mess or debris from the job to be recycled, you can get to know your installer and have a chat with them here.

How else will they help?

Your installer is dedicated to you. They’ll make sure you know exactly how everything works, and you can visit the FAQ page.
So pop the kettle on, relax, and they’ll show you exactly what’s what.
