“Richard took out my old gas fire and back boiler. He arrived on time was very polite and friendly He cleaned up afterwards and even took my old fire and boiler out to the garage for me. Will definitely use him again to service my new combi boiler”
“I've been using Chelmsford Gas Services ever since they installed my boiler several years ago, and have complete faith in them.”
“My thanks to Richard, Bam, and Conner, for the effort they put into to sort out my Baxi Brazillia wall heater, particular thanks to Bam for all his excelent work, and persistence in sorting the unit out, Chelmsford Gas Services always do a great job, and I would not hesitate to recommend them they do an excelent job, and should be the first port of call for any one requiring any work done, or a completely new heating system. Thank you again..”
Detailed reviews
Overall, I am extremely disappointed with the level of service and workmanship from this company. They have serviced my boiler twice now and immediately after each service the boiler stopped working. Based on these experiences, I would not recommend this company and will never use them again. Last year, following a routine service, the engineer left a condensation valve open, which resulted in a leak that caused water damage in my kitchen. This year, within just a few hours of servicing my boiler, it stopped working and displayed an error code. When they returned I was told that the PCB needed replacing at a cost of nearly £1,000. Thankfully, I sought a second opinion. That engineer quickly identified that the issue was not the PCB, but simply a faulty gas valve, which he replaced without issue and not at a cost of £1000.
Reply from the business
"Thank you for your feedback, it’s genuinely important to us. We value all customer comments, as providing a high standard of service is always our priority. We’re sorry to hear about your concerns and would like to clarify a few points. Last year’s condensate issue related to a loose plastic connection commonly found on certain Worcester Bosch installations. We returned promptly and resolved it at the time. The separate review referenced involved pipework boxed in too tightly, which was dislodged when repositioned, this was also rectified immediately. On the recent visit, the boiler was serviced in line with manufacturer guidelines and was operating correctly when we left. Electronic components can occasionally fail coincidentally after power has been isolated and restored, this does not mean the service caused the issue. When we returned, diagnostic checks indicated a PCB fault based on the error codes present at the time and a quotation was provided. No repair was carried out by
The usual excellent service from Chelmsford Gas Services. Bram arrived very punctually, a text informing of his arrival time and a link to track his arrival time. Bram was polite, courteous and friendly, getting on with the job (annual boiler service) efficiently and tidily (absolutely no mess). He solved an issue with our largest radiator, for no extra charge.Bram (or any of his colleagues) are welcome back any time.
So glad we’ve found this company . Arrived early , had been kept updated with arrival . Very friendly and efficient . And made sure everything was in order throughout . Wouldn’t hesitate to recommend this company and will be using again .
I would certainly use this trader again.
Offer a 2 hour window for the arrival time which is rather long for a one hour job. However on this occasion the engineer was on site within 30 minutes of appointment start time and would have been earlier if the location was easier to find from the postcode/address. Engineer was pleasant and efficient - no complaints about the speed and quality of the work.

As always great communication, professional service, would totally recommend.
Bam and Connor were excellent even though job turned out to be more complicated that we realized. They were polite, fun and very professional. The job took longer than expected but we were not charged any more than estimate Marion
Chelmsford Gas Services have been looking after our home for several years now. They are proactive in contacting us to organise our yearly service, and arrive promptly and provide excellent service. I would not hesitate to recommend them, a great local family run business.
CGS are always, prompt, efficient, engineer very pleasant and clean worker. Keep you clearly informed of timing, work done etc. happily and confidently recommend.
The guys from Chelmsford Gas are always punctual, polite & keep, us informed of what needs to be done & go through what they have done once the job is finished. Would thoroughly recommend.
Boiler Service carried out by Bam. very friendly and professional. A problem occurred toward the end of the service and as the boiler was under guarantee with Worcester Bosch he had to call them to fix. This wasn't much of a problem because they were able to send an engineer within 15 minutes. Bam returned on the 27th to complete the service and issue the necessary certificates. We were really please with the service we received from Chelmsford Gas Services. Good Company will be using them again.
Been using Chelmsford Gas for a number of years now , have had a new combi boiler . 2 new extra radiators supplied and fitted . central heating pipes moved , new gas hob fitted .plus annual service for boiler every year . I have now subscribed to there monthly plan for emergencies and servicing . As you can gather I am a very satisfied customer .. Bam serviced our boiler on weds , so nice and professional, clean tidy job ..highly recommended ..ps, you get what you pay for
Had my boilers serviced by Chelmsford Gas Services, usual knowledgeable, efficient and informed service by the very pleasant Bam Douglas, He even told me that I may need some work at the next service, it's nice to have a years notice about something that may need doing, makes budgeting easier. If you want a company that does a very good job, using reliable people, look no further.
Prompt quick and explains all processes
Having had this company replace my very old boiler in May 2024 with excellent, professional results, I received a timely reminder email for the first annual service. Their engineer, Bam, arrived at exactly the time agreed and set to work after our initial chat. Bam was friendly, knowledgeable and cheerful and I was confident that his work was carried out to Chelmsford Gas Services' very high standards. Thanks from a happy customer.
