Brilliant service provided by CGE. Jack, the operative who attended was polite, friendly, sorted the issue quickly and left everything spotlessly clean. Would highly recommend.

CGE Southern carried out kitchen ventilation filter changes and catering gas works at Pangbourne Primary School, Berkshire, and the standard of work was excellent throughout. Their engineers were professional, fully compliant with commercial gas safety requirements, and worked efficiently around school hours to minimise disruption to catering operations.

I called CGE Southern for an installation of an outdoor tap, a young man called Zack arrived to carry out the job, he was very polite and personable from the outset. The job was quite awkward and required Zack to move quite a bit of equipment and various items from the shed before he could gain access to the water supply. He did this without complaint and with complete care. As I am a disabled man in a wheelchair, I was unable to clear this space in preparation. There was a difficulty in locating in the main stopcock, which is located in a different road. Zack took this in his stride and contacted the waterboard and resolved the issue. The work was completed to the highest standard. I am very grateful to CGE. Thank you

We have used CGE Southern for over a year now for callouts and servicing to all our M&E equipment. They have been consistently outstanding in the delivery of their services. Their team, both office based and engineers alike are professional, knowledgeable and flexible in their approach to all aspects of delivering a first class service. I cannot recommend CGE Southern highly enough. Their costs are always realistic with honest and comprehensive quotations.
