Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 8 years on the register also points to an established business rather than a brand-new one.

2 separate delivered containers
I bought a container doing my new build. What a fantastic service, quick response, clearly communicated and delivered by an exceptional driver great value for the cost. I needed another so called George who moved this quickly for me and the same driver delivered it on a bigger lorry which worried me as its toght access. No issues for this driver Mark who had been before, a real master of the drop off not one moan. My builder cant get anyone to deliver but George can sort him out and send super driver. We'll done guys excellent customer service.

Darren came to my property at short notice to repair my boiler. The Flue was faulty meaning my gas was switched off by the warranty company. (Flue not under warranty) he replaced the Flue and explained all work carried out, for peace of mind. I would undoubtedly use this company again. Thanks for everything.

I found CHS Glasgow on a local social media group when I needed a gas safe engineer at very short notice - same day short notice! - to help me disconnect a gas appliance to allow other work we had going on in the house to take place. Darren was extremely helpful, managed to fit us in to his day and said he would come back to reinstall the appliance whenever we were ready. Friendly and polite service throughout, and really prompt to respond and arrived when expected. Can’t recommend Darren and CHS highly enough.

I was worried about getting my central heating boiler replaced. However, everything went so smoothly. Darren and his employee Robert arrived on time. They respected my property by providing protective coverings for my Amtico floors and work surfaces. They worked away for the full day. They completed all that they were contracted to do. They tidied up after the job was done. Darren explained the working of the boiler and left me the manual. He sent off my details for my guarantee and Worcester Bosch have confirmed the registration. I couldn’t have asked for a better service. I’ll use them again for my annual service. A good job well done!

Excellent from start to finish
We have recently had a new boiler installed Darren and his colleague. From the outset Darren was professional and amiable and I felt I was able to trust him to do the job right and install the right boiler for us. We didn’t have to wait, they came when they agreed and were tidy and respectful of our home. The boiler is working really well and we feel reassured that if we happen to have any issues, we can call him at any point. I whole heartedly recommend this company.

Excellent Service
Can’t recommend CHS Glasgow and Darren highly enough. We needed a boiler replacement, and from initial discussion and quote Darren explained everything well and made recommendations, tweaking to meet our requirements. The job itself was completed to a high standard - professional and friendly service - and we couldn’t be happier with the new system. Darren was also good enough to take care of an extra task on the day. Overall reliable, trustworthy and friendly.

New boiler installation
We contacted CHS Glasgow who provided a very competitive quote for a new boiler. The old system was over 20yrs old with a badly fitted flu and all needed replaced and moved. Darren recommended a Valiant boiler that ticked all our boxes. On the day of install Darren laid sheets to protect carpets and went about the job with minimal fuss. The old boiler was removed and discarded with the new boiler fitted in quick time. The flu needed to be moved for an upcoming loft conversion and Darren took time to explain the options and the relative pros and cons of where it should go. After discussion this was completed and we could not have been happier with the result. After the boiler was installed Darren recommended a power flush as the radiators were very dirty. Again this was carried out professionally and he showed us the system draining and the accompanying residue. It was obvious that this was required. Finally, Darren showed us the new Wi-Fi controls and how to get the best from the boiler. All in all we were highly delighted with Darren’s work and would most certainly recommend CHS Glasgow.

Reliable and good communications
I phoned him just before 12 noon to say I had a plumbing problem. He was on a job but said he would call at my house when he finished, probably after 5. He sent a text to me when he finished the job and was on his way. When he arrived he went under the floor and checked out the pipe work I was concerned about. He confirmed that everything was OK and charged me only his basic call out which I considered very reasonable. He was excellent at communicating with me initially, taking the initial call and explaining when he expected to be able to see me, then updating me. When he did arrive he was very polite. After he had been under the floor and checked out the pipework he explained in detail how the pipework was arranged and though the original installation was not as he would have done it would work ok and did not need further work. I thought that his call out charge was very reasonable.

CHS Glasgow: Complete system replacement
We have various quotes, including the big providers, to replace our 30+ year system, and CHS (Darren) provide the most detail about what it will require. He took all our concerns to heart, and on the day even found a work around which led to a much nicer outcome. Everything was done perfectly and in short time. Thanks Darren for your professionalism.

Great work Darren
This was the first time we have used CHS Glasgow. Our gas boiler was installed only a year ago during extension work to our house so it required its first service. We were very impressed with the way Darren explained everything he was doing and indeed I think we learned more than my husband and I knew about the workings of the boiler. We will certainly call him for the next service and would recommend his company to our friends. Excellent all-round workmanship.

Highly recommend - true professional
We were concerned that our existing 5 year old boiler was underperforming and possibly too small to cope. Darren responded very quickly to the initial query and came out to visit the same day. Having assessed the situation, (the heating system, how we used it and our house) his conclusion was that rather than a new boiler, we would be better served through trial and error adjusting the thermostat and heating settings. Although it was the end of the day and later than he had appreciated, he took his time to provide honest and helpful advice. He could so easily have simply sold us a new boiler installation. Darren’s pre-visit communication was first-rate, he was very respectful of our home whilst he was in it and he is clearly very passionate and knowledgeable about heating. Although we haven’t bought any services from him yet, he’s left us feeling like valued customers who will return to him. Thank you Darren.

Goes 'above and beyond!'
My husband came home from hospital after major surgery and despite our boiler going full blast, our house was cold. Darren had done work for my brother and I'd been very impressed with his professionalism. I left a message with his wife and he phoned me back just after 7pm. He heard how worried I was and came out to see what he could do. He advised us that we needed to renew our boiler (it was nearly 20 years old) and have our system flushed out but to still keep our present radiators and thermostats as they were ok. He re-jigged his schedule so he managed to fit us in before Christmas. The weather turned bitterly cold and his wife phoned to ask if we'd like some extra heaters which we gratefully accepted. Darren came when he said he would and we found him to be knowledgeable, conscientious and extremely hard working and our house has never been as warm. He explained what he was doing and why, and kept us in the picture all along the way. He tided up after himself and left our house the way he had found it. Our son and daughter were both here on Christmas Day and have both taken his phone number to have work done in their homes. Couldn't rate him highly enough!

A true professional-highly recommended
I'd used Darren to service my boiler two years earlier as a Which? Trusted Trader and had been impressed. I attempted to get him back a year later but it was in the middle of COVID and I was unable to reach him, so I went with someone else who came and did a cursory job. So, when it was time for another servicing, I tried CHS again and was pleased when Darren responded. The engineer that Darren sent was meticulous. He informed me, at the end of an hour of poking about, that the boiler (15 years old) was unsafe. He called Darren and informed him of the same. I was very keen to get the boiler replaced, especially as we had guests scheduled to come stay the following week. Darren was able to prove two quotes for two possible replacements in a very short timeframe and able to rejig his schedule to fit us in the very next week. Fitting the new boiler involved some unexpected challenges but Darren was able to overcome most of them until it came to commissioning the boiler late that afternoon when it turned out Vaillant had not included a key part. Darren was able to contact the Vaillant rep that evening, who appeared at my address the very next morning with the necessary part, and the installation was complete. When there was a potential problem six months later, Darren came out at 9am on a bank holiday to check the boiler out. I remain very impressed with Darren and would strongly recommend CHS Glasgow to anyone looking for a true professional.

Our heating system was 24 years old and we decided to replace before the winter. Looked up heating companies on Which for reliability and good reviews. We got a few quotes but CHS Glasgow stood out. Phoned the company number and spoke to Pamela, Darren's wife who was very helpful and said she would get him to contact us. Darren contacted us within the hour and came out later the same day. Was very thorough in assessing what we needed and listened to our preference to go with a Vaillant boiler as we had got a good run out of this make. The work was carried out by both Willie and Darren. They were very prompt and professional. We were informed the whole way the process of supplying and fitting. Efficient and tidy workers. Took away all the old radiators, boiler and rubbish. They even fitted a new kitchen sink tap that was leaking while they were doing the heating system. Darren then came back later on in the evening following completion of the job to ensure we understood how to use the thermostat. Extremely happy with the work carried out and have no complaints following a few cold snaps and high winds. System running like a dream. Would definitely use this company again.

I was very impressed with the professionalism and workmanship of Darren at CHS Glasgow from the first visit through to the testing and handover of our new Vaillant boiler. As a former owner of a plumbing and heating company I recognise good workmanship and give this company top marks.

Reliable, Trustworthy, Helpful, and Friendly
The team are so friendly and helpful. Our boiler broke down and from the initial phone call right through to the work being finished, we couldn’t have had better service. The team helped us as much as they could over the phone, arranged an appointment for a home visit promptly, and communicated clearly and openly with us through the rest of the work. He went out of his way to schedule our boiler replacement as soon as possible so we wouldn’t be stuck without heating or hot water. We are more than happy with the work done and to continue using this company for aftercare and future boiler services. Would definitely recommend CHS Glasgow to anybody and will use them again in future.

Darren was so helpful from start to finish. Above and beyond to be honest. The work was completed to a fabulous standard. Very tidy worker and extremely kind manner. Darren found a leak as pressure was dropping and this was fixed within the hour. I would have no hesitation in recommending Darren. Thank you once again for a fabulous service!

New boiler and system upgrade, top service
I needed a new boiler after my existing system decided to pack it in. Darren came around and the advice he gave me was first class. He Listed the options for me and I was able to change the boiler, upgrade the overall system and I’m really happy with the work. Darren is very professional and you can see that in his work, how he deals with his customers and how he leaves his work environment. Easy 5 stars.

Highly recommended - professional customer service
I contacted CHS based on faults encountered with a pre-exisiting, ageing boiler in a newly-purchased property that required us upgrading to future-proof the kitchen. Darren's advice on the boiler upgrade was helpful/professional and he was very good at communicating the work required both beforehand and during the installation process as well. I'd highly recommend CHS based on this pleasant, professional experience which was especially appreciated by myself as it took place around other work taking place in the property as part of the kitchen update/upgrade.

Outstanding service - Highly recommended
Our 8-month old boiler had broken down overnight leaving us with no heating or hot water. It was a Sunday during the very cold spell in February this year many people in the UK were experiencing the same problem. As our gas engineer who installed the boiler could not attend because he was self-isolating, I tried contacting the supplier's customer service emergency line, but after hours of being put "on hold" without success, our gas engineer recommended Darren. Darren answered the phone promptly, posed various questions, gave possible scenarios for the problem and advised he could be there in a few hours, giving us a price for the callout and any work. He showed up as promised and managed to get the boiler up and running but said it would need to be checked over by the supplier. Through his network, he managed to arrange for Vaillant to attend in the next day-or-two for a full service under guarantee. He also called me the following day to make sure that Vaillant had indeed contacted me to fix a time for this service. They had not, so he contacted them again and ensured I got confirmation. He followed up with me to ensure I was happy with the result. We shared findings with the gas engineer who installed the boiler, who returned to make minor adjustments. Darren is clearly knowledgeable in his field of work, passionate about it and strives to ensure top quality customer service by liaising with other professionals to get a job well done.
