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.
Great service! Really quick, efficient and effective.
Very fast response time to sort an issue at one of my rental properties which is important as a responsible landlord . Georgia in the office couldn’t have been more helpful Thanks
I phoned CGE southern explained my boiler was down Andy did not hesitate to make the time to help. Talked through every step and got to work. My house was spotless when the work was complete. I coundt recommend anyone more.
Very impressed came out really quick and fixed the problem in no time very professional would definitely use them again 5 star service
Jack and Alfie were great guys who worked exceptionally hard for a full weekend to get water back on in a critical commercial situation. Would recommend CGE Southern without a moment’s hesitation.
Andy performed gas safety checks for two properties and was very profane courteous. Great service.
CGE are Always there for advice, very quick responding to quote for jobs and attending call outs, CGE have done several installs for us and very impressed with the Results,work, knowledge and professionalism of their engineers.
As a client requiring diverse gas and heating work, I couldn't be happier with CGE Southern. From emergency repairs to scheduled maintenance, they always maintain an impressive level of quality. Their team is always punctual and highly professional, showing great respect on site clients and their property. Most importantly, their technical expertise is outstanding; every job is completed correctly and if not possible to be completed first time then quotations are submitted in time, with detail and excellent value. It is a genuine pleasure to work with a contractor who is so consistently reliable.
I called CGE Southern late in the evening after our boiler packed up. I spoke with Andy, who was incredibly polite and helpful, and he arranged for an engineer to be with us by 9:30 the next morning. James, the engineer, arrived right on time. He was fantastic, quickly diagnosing that the boiler had drained itself. He serviced the unit and fixed the issue, all while clearly explaining what he was doing every step of the way. Both Andy and James are a true credit to the business. I cannot recommend CGE Southern highly enough and have already passed their details to all my friends and family. Professional, punctual, courteous, and just downright brilliant. Thank you!
CGE southern carried out the works on our restaurant all of there staff were professional, knowledgeable and concicencious. Would definitely recommend them.
Jack was amazing! Can’t thank him and his apprentice enough for all they did! Left hallway spotless! 100% recommendation
What a great find. We first used CGE when looking for a problem with low water pressure in our small hotel installing a commercial pump & tank. They came up with a housing and access solution that they installed and fitted themselves. This saved us nearly 10k and we dealt with one company when before it was builders and plumbers and gas engineers. Since then we’ve called them to help connect underfloor heating to our boiler. Matt Andy and Harry have also fixed our domestic boiler when we ran into issues. They are professional friendly and have come up with solutions to a range of issues we’ve had. Always available / even out of hours and unsociable days. They’ve had people on sight fixing things when no other company could. We are going to switch over to them for all our gas and boiler requirements and would highly recommend them to others. Thank You all. Steve & Mubi and team at Ashbys. Great Company & People - thank you.
From calling up and dealing with our heater, the service was first class. Fast, efficient and friendless service. 100% recommend 👍
Great company to work alongside, always going above and beyond to keep the projects running smoothly
Thank you Harry it was a pleasure having with with us this morning for our commercial annual gas certification. You are part of a young generation of engineers doing a brilliant job. Punctual,clean,tidy,efficient, knowledgeable and a great person to have on site - you smashed it buddy thank you! See you next year Mike
Thank you so much for your help with my boiler! Fab service with Andy, highly recommended! Will use again!
When the boiler failed at one of our rental properties, Andy had one of his team attend within the hour. GGE Southern quickly analysed the fault, repaired it and left our tenant with a fully operational system. A great team, excellent service and will be using CGE Southern whenever the need arises. Would not hesitate to recommend.
Really happy with the service provided by Matt at the RBL Fratton. Matt was polite and courteous and resolved our ongoing heating issues quickly and efficiently. Thank you.
Andy was super helpful when I had issues with my boiler pressure. Response was very quick, and had my hot water running back in no time! Highly recommend for quick and attentive service
The radiators I had removed and replaced with new ones was carried out in a very professional way The men were very polite and carried out the work efficiently and they were very clean even hoovered up after very pleased with the work highly recomend this company
I did like the follow up visit to see if all was good the following day. Would of been 5 star if it was dealt with at the first visit but was done the following evening. A great end result and a great attendance time frame. Many thanks to. James, Nathan And Alfie. Kind Regards Neale Facilities Manager Amery Hill school
Great service, polite and professional over all very pleased with the service provided. Would highly recommend these guys and would definitely use again.
Andy and he’s team carried out 1st & 2nd fix to one of our loft conversion projects. The job run very smoothly and he’s guys had a professional attitude. The job was priced before works had commenced and was on time and budget. Thanks for all your help and there will be many more in the pipeline for him and he’s team.
Needed the wood boarding beneath our gravity fed water tank replacing. Andy was great. Very professional.
Great firm, trustworthy and reliable. Trevor came and fixed our office’s air con at a very reasonable price. Very happy ☺️
CGE have been fantastic to work with as a company. We're so grateful for their professionalism and how easy they are to communicate with. Would absolutely recommend them to anyone.
CGE Southern did an amazing job with maintaining and fixing the air conditioning system at my gym. They were professional, efficient, and made sure everything was perfect for my workplace. They worked around our schedule with minimal disruption (to myself, staff and members!). Highly recommend them for top-notch service.
We experienced an issue with the boiler in our unit, and CGE Southern responded the same day. The service was incredibly fast, and their communication was excellent throughout. When parts were needed, they returned the very next morning to complete the job. Outstanding service from start to finish
Excellent service, thanks so much
Mat & Alfie were very clean & tidy, easy to get on with & did a great job
Amazing service, other service providers can't even compare. Andy and James are legends 💪
I’ve just started working with the company and I’ve never felt more welcome or supported within a role before. Not only are they great to their staff but the customers are at the core of everything they do and they well and truly put them first.
Extremely helpful throughout the whole process, would happily recommend to anyone.
Matt arrived quickly and got the job done efficiently. Great communication and cleared up when finished. Thanks for an excellent professional job.
First class service. See the job through to the very end no matter the time!
Went above and beyond to find a solution for us. Worked quickly and kept me updated until job done
The guys who came out to sort my gas pipe from CGE when it was damaged came to my property quickly, and were very good at keeping me informed about what was going on. They were lovely to have in my house at what was a stressful time, they tested everything thoroughly to ensure it all worked again, and left things as tidy as they could once they were finished. Highly recommend.
Reliable and professional. A prompt response to a request we had which was dealt with very well. The engineer that turned up was very polite and managed to pick up a couple of things that needed looking into, which is something other local companies have not done since our refurb began. Will be looking to have CGE over again if we require it.
Matt and Alfie attended today to re-hang a radiator. They were both polite and friendly and explained exactly what they were doing. They were considerate and asked if they should take off their boots. They checked our heating system was in full working order before they left and explained what to do if the pressure drops. Highly recommend them for any future work.
Reliable, trustworthy and honest company. Communicated throughout so we could manage and update our residents . Problem solved the issue and managed the remedials quickly and efficiently.
Really great service from James, he fixed my issues with my boiler promptly and answered all the questions I had. Really helpful, thank you! Also Andy was able to help me out by speaking to me on the phone late at night and talking through the issue I had.
Matt was very helpful, kept me updated and fixed my issue.
Great experience! From start to finish the job was delivered on time and with the upmost professionalism. Would highly recommend James, Andy and the team!
Fantastic service. Quick and very thorough. Sorted out my emergency at work really well and went the extra mile. Will definitely be using again. Thanks!
Mark & & Alfie were absolutely amazing. They respected my home, got on with the job and cleaned up after them. It didn't take as.long as I thought it was going to.
Great service with a bathroom repair and renovation. It was a particularly delicate job involving a macerator and hidden plumbing. The job was well executed in a timely manner. Thanks Matt! You're a legend!
Prompt, knowledgeable gas engineer, excellent communication. I would highly recommend.
excellent service! definitely recommend, they got our commercial oven running on the same day as our desperate plea went out, we`ve now arranged a yearly maintenance schedule with them.
Amazing job. After a water leak the team fixed my bathroom and it now looks fantastic. The team were friendly, professional and helpful. Brilliant workmanship. We are really pleased with the job they have done and we would highly recommend them.
Our salon boiler had a pretty serious leak. Andy from CGE southern, came straight out to assess the boiler, stopping the leak and draining the system, preventing any further damage. Andy dealt with the situation in a quick and professional manor, sourced a new boiler and parts for the next day. Matthew at GCE came the next morning to dispose and for the new boiler, leaving the place looking clean and tidy. I highly recommend GCE for their professionalism and high standards of work.
Excellent service with knowledgable engineers. Would highly recommend. ⭐️⭐️⭐️⭐️⭐️
CGE carried out the plumbing and heating to my loft conversion and I’m over the moon with the finished results! Highly recommend them.
Good communication throughout , will definitely be using again. Cheers guys
Andy turned up at very short notice very quickly. He was very professional and managed to get us sorted out.
We had our bathroom sink replaced after an accident had smashed a significant part of the sink off. NFU Mutual sent a plumber to repair the problem. The contractor was courteous and efficient and worked cleanly. The sink was replaced with a similar model of similar quality quickly without any fuss or inconvenience. Many thanks.
Excellent Plumber. Called, out out of hours, arrived within the hour. Really professional, knowledgeable and polite guy arrived called Andy. He identified the issue straight away, isolated the water and cut a piece of pipe and inserted a blanking cap as a temporary fix as the issue was with a earlier plumber from a different company who had drilled a main water pipe, filled the hole and left. I will without a doubt be recommending this company and Andy to family and friends and if you are looking for a Plumber look no further. It was so nice to have a workman respect your property, wiping his feet and doing an excellent job. 11 out of 10 Andy with a huge thank you as your swift intervention stopped what could have been a sizeable food.
CGE are very friendly and professional company

I am well pleased with the services that you have provided. Matt displayed professionalism from the minute he entered the property to trace and repair a leaking pipe. It was a tricky task given the location of the leak but his patience and evident knowledge/experience made good of this repair. Very tidy and polite; I would recommend this company. Thank you 🙏

Great, friendly service. Thanks very much
Great service again from Andy and team. Clear advice on what is needed and quick, clean and tidy work. Boiler, radiator and tap all fixed.
Andy at CGE has serviced my boiler for a couple of years, and undertaken any work needed. Standard of work is always great, his advice always puts the customer first, and I’m always happy with the end result.
Spoke with Andy who booked me in short notice for a boiler repair. Him and Matthew were really informative, considerate and friendly and did a fantastic job. I would recommend CGE to anyone looking for gas / central heating work to be carried out.
Thorough job done promptly by an extremely professional, considerate, personable young engineer.
Quick to arrive, very helpful, clean and tidy would definitely recommend
We used CGE Southern to remove our old boiler and supply & re-site a new one along with the install of several radiators plus a new toilet, sink and all plumbing involved, couldn’t of asked for a better tidier install, plus he will also service this Annually, we have and will always recommend Andy @ CGE

We had been let down by a previous company, after speaking to kirsty she organised an emergancy call out and the service we recieved was outstanding. Will definetly use them again.
Recently our carbon monoxide alarm went off which resulted in our gas having to be turned off by an emergency engineer. Andy understood that we had a family which meant that this was very challenging. He went above and beyond to get out as promptly as he could and quickly resolved the problem. He clearly explained what had happened and how he resolved the matter. Brilliant professional service which resulted in minimal stress on our family!! Highly recommend
Very professional and knowledgeable
First class service every time. Always feel very well looked after . System running great :)
Andy had to take on a very difficult job for us - boiler in awkward position, irate tenants having their say, external water supply being tardy to respond but he dealt with it all and resolved the issue.
We had a gas system we needed purging on a new industrial proper we had purchased. Andy was quick and efficient and got everything sorted and safe for us. Top service and top team!
These guys were great! Needed a safety certificate for a commercial gas installation urgently. They appreciated our situation and shuffled things around in order to squeeze us in the next working day. Informed us of reasonable cost prior to carrying out work efficiently and tidily. Now our go-to commercial gas engineers! 👌🏻
Great plumber and he knows what he’s doing i would highly recommend.

All waste from installation was taken away the next day. Good value for money, with high quality products being supplied. All in all I am very happy with the process as a whole and would highly recommend using their services.
Andy originally fixed a fault with my boiler. I was so impressed with his customer service we booked for him to return to carry out a service. New parts were needed which Andy had no issues in getting. He is incredibly knowledgeable, clean and tidy. I would highly recommend Andy to anyone need help with their boiler.
