Commercial Plumber FAQs – Everything you need to know

Posted by: Carly Temple on 4th May 2021

Last year, we expanded our range of services and invested in Commercial Services training.  One of our commercial engineers – Matthew Williams joined the programme and became a fully qualified Commercial Gas Engineer.  A year on, we asked Matt, some of the questions he gets asked most often about this new range of skills.

What is a Commercial Gas Engineer?

A Commercial Gas Engineer is specialised in working on commercial businesses, schools and housing.

There are similarities in the type of work that a domestic and a commercial plumber does, in that they both work with plumbing & heating systems including boilers, sewers, and pipes. However, a Commercial Gas Engineer will normally work on much larger sites.  These sites, will often come with a much more complex water supply, waste, water pressure and boiler systems and infrastructures that follow blueprint designs.

What type of work does a Commercial Gas Engineer do?

They would offer the following types of services:

  • The design of plumbing systems for commercial outlets
  • Replacement of entire commercial property plumbing systems
  • General maintenance (repair, piping and installation services)
  • Plumbing maintenance contracts for businesses
  • Clearing of blocked stormwater drains and sewers
  • Water supply system (installation, maintenance, and repair)
  • Drinking water lines (installation and maintenance)
  • Backflow prevention systems (installation, maintenance, and repair)
  • Fire systems (installation, maintenance, and repair)
  • Internal and external pipework (installation, maintenance, and repair)

What hours does a Commercial Gas Engineer work?

Carshalton Boilers often work outside of normal Monday to Friday 9-5 hours as there are some commercial plumbing jobs that need to be done outside of businesses hours. We also offer a range of commercial plumbing, heating and landlord packages, some of which cover emergency repairs.

What qualifications does a Commercial Gas Engineer have?

In the UK you are required to complete and pass a City and Guilds National Vocational Qualification (NVQ) Level 2 and 3 in Mechanical Engineering Services for Plumbing.
