Very quick response , knowledgeable and polite service. Will certainly be using again in the future .
Very good service - fast and reliable but most of all, genuine and kind. Thanks, Amir! Recommended for landlords and businesses!
The team at H3gs were very professional, quick and helpful. Amir went above and beyond when another issue arose and ensured that the team could come back the next day to sort it. Very satisfied.
I had a great experience with H3GS Heating! Their team was professional, punctual, and very friendly. They quickly diagnosed the issue with our heating system and fixed it efficiently. What I really appreciated was how clearly they explained everything—they made sure I understood what was being done and why. The work was neat and thorough, and their pricing was fair and transparent. I never felt like I was being overcharged. Overall, I’m very satisfied with their service and would definitely use them again in the future. Highly recommended to anyone looking for reliable and high-quality heating services!
Great service from Amir and the team, they came out quickly, communicated clearly, and were always professional. Can’t fault the work they did to replace our boiler, and repair our stopcock and radiators. Wouldn’t hesitate to recommend them.
Awesome service, fixed my leak within 24 hours, fair price, great communication. Recommended
Right from the start the service we revived was professional, friendly and totally transparent. We were looking for a complete combi boiler fit and bathroom plumbing job ASAP. Work was discussed, organised and executed quickly and very well. Communication was great throughout and the guys are very approachable and reliable. Oh, and adaptations were worked around with no fuss. Highly recommended. Took a great deal of stress of our plate.
They were simply great...gave me all options available and carefully explained all the pros and cons of each option. They changed my boiler in quick time and after they finished...they ensured everywhere was properly cleaned up and arranged.
Amir and his colleague recently installed our new Vaillant boiler, and we couldn’t be more pleased with the experience. From start to finish, they were responsive, clear, and communicative – a refreshing change from many of the tradespeople we’ve encountered in London. The quality of their work is outstanding. They took great care in the installation, and the boiler runs perfectly – it’s so quiet we hardly notice it’s on! Their professionalism and attention to detail really stood out. I wouldn’t hesitate to call them again for any boiler or plumbing work, and I’d absolutely recommend them to anyone looking for reliable and trustworthy engineers. An excellent experience all round.
H3gs were recommended to us after our boiler packed in. They were responsive and gave us a quote upfront (something we've learned to appreciate!). They sorted the problem quickly and we had hot water within no time! On their recommendation we booked in a service which was completed promptly. We will definitely be using them again!
We had an excellent experience with H3GS Heating. The heating service engineer was professional, efficient, and completed the repair without any delays. The company is highly responsive, accommodating urgent appointment requests with ease, and proving to be completely reliable. From start to finish, the service was seamless, and we felt reassured that our heating system was in good hands. We would definitely recommend H3GS Heating to anyone in need of a trustworthy and efficient heating service!
Great customer service and a fantastic job done fitting a new boiler. Very responsive and provide full detail on what they are going to do and why. Would most certainly recommend them to others
Thank you for all your help and service. I would highly recommend this company for the work they have done at my flat
Amir and his team were extremely responsive, highly professional and very helpful. They were able to sort out a replacement boiler and fix underfloor heating within less than 12 hours notice.
Amir visited my property and was able to locate the problem regarding the water pressure for both the hot and cold water. [unlike the 2 previous plumbing companies who advised to call another plumber] Having recently had a new boiler installed Amir gave a couple of suggestions to resolve the problem. Over the weekend Amir worked on a plan on the work required for a new water feed into the property. Within 4 days Amir was available to proceed with the work replacing the normal gas boiler with a combi boiler and new water feed for the property. I would recommend H3GS Heating, they gave me advise how they could resolve the problem and the work they would be doing. They were very professional, kept the property tidy whilst doing the work.
Elderly parents needed a new boiler. Visit and quote done quickly. Had text conversation about suitable thermostat. So communication was excellent. On day, arrived as agreed, stayed late to finish the job and tidy up. They were understanding of my payment delays due to Barclays. So nice people to do business with. Also, I later decided the thermostat was not in a convenient place and they came back and re positioned it the next day. Highly recommended.
We were recommended H3GS by a neighbour and their service has been incredible. Amir and his colleagues are responsive, reassuring and efficient. Amir took the time out to explain everything clearly and kindly. I would highly recommend them to anyone who needs a reliable and efficient service done to a really high standard.
Would definitely recommend H3GS and will be using them again. Our boiler stopped working and the team were super responsive. They were able to come and help me fix the issue the same day at a resonable price.
I can only mirror what has been written in the review below. H3GS is a fresh breeze of air and restored my faith in tradesman. Twice I used H3GS. Once for a real emergency of water escape, the 2nd time to replace parts of the water supply. Both times H3GS delivered professional service. Amir was quick, calm and kind. He took the time to explain the situation with such great energy and gave me great guidance in what to do if I ever experience escape of water again. Its very refreshing to learn something along the way. I can strongly recommend H3GS and wish them great success for their business. Thank you once again for arriving so quickly and fixing the situation in my emergency.
