Zsolt came and did a service for our gas boiler, he is always very helpful and quick to respond - wouldn't hesistate to recommend him to others.

Previously had great experiences with them but over the past year or 2 Zsolt has been getting more and more rude to the point where he just called me up and yelled at me about needing to change the job when I had no control over the situation (GTC not communicating with me nor their team, which then changed what Muller needed to do). I will no longer be working with them nor recommend them.

Zsolt and his team were amazing. Great communication, prompt from quoting to starting the job and quick and tidy completion. Would highly recommend.

Explained what he was doing and asked questions about where I wanted things. Found a fault with the boiler and explained I should be under warranty to get replaced. Friendly and has done good

I called Muller Gas Tech and given an appointment. They turned up on time, explained what needed to be done and carried out repair professionally and at a reasonable cost. I would definitely recommend this company.

excellent service told me the problem with boiler and problem solved will use him again
