  Oil Boiler Installation

  Totally professional

  GMX Ltd replaced my ageing electrical system for an oil fired combination boiler and tank. Joe was extremely helpful in the whole process from quoting the price to its installation and explaining its operation. Every aspect of the task went smoothly and on time as predicted by Joe. I would highly recommend GMX Ltd if you want a consummate professional heating engineer.

  Friendly and professional

  The guys called round to figure out how to install an oil heating system in my home. Free quote / survey. They were very professional and friendly. I look forward to getting their quotes and design ideas to proceed with the project.
