I'm writing to express my sincere appreciation for Mr. Singh's exceptional work on my new boiler installation. He was incredibly helpful, offering various options and clearly explaining the associated costs.

His work was not only fast but also remarkably clean and tidy, with everything completed to a high standard. I am thoroughly impressed with the amazing job he did.

I would highly recommend him without hesitation for any gas related works.

From start to finish, a very professional company. I had a new boiler fitted after a very cold New Year’s Eve. I was kept in the loop at every stage of the process; deciding on budget, convenience and quality and finally the timeline. I would definitely use them again. I am so pleased to have hot water and heating again.

I recently used Harmeen for a boiler installation and couldn't be happier and more satisfied with the experience. Everything was handled professionally and communicated clearly. Harmeen arrived exactly at the scheduled time and completed the installation efficiently and neatly.
Also, the first service after installation is free!
Would highly recommend them and they genuinely care about doing a good job.

Harmeen was absolutely outstanding! My tenant’s boiler broke down and he responded quickly, arriving exactly when he said he would. He diagnosed the problem straight away, explained everything clearly, and had the boiler back up and running in no time. What really stood out was how professional, polite, and considerate he was — both to me as the landlord and to my tenant who was left reassured and comfortable. It’s rare to find someone so reliable and trustworthy in this trade. I’ll definitely be using Harmeen again for any plumbing or heating issues, and I would highly recommend him to anyone looking for quality, dependable service.

Harmeen and his team were very helpful throughout the renovation of my 2 bed flat. Changing the boiler, radiators and pipe work. He did things to a high standard and was very quick in responding to any extra requests I made. I’d definitely recommend
