Each and every WarmInstaller is thoroughly vetted by WarmZilla before fitting a boiler and with every boiler installation, they are required to complete a pre and post-installation checklist to ensure that each and every job is completed to very specific standards.

After a job is completed, we take multiple photographs which are sent to our engineering team in-house for review.

This is how WarmZilla ensures high standards of boiler installation, on every boiler replacement we fit.
