Abseloutley class. Came the same day fixed the issue. Not had any problems with my boiler since. Very quick and efficient service.
Masoud has just completed a repair and service of my Vaillant Combi boiler. He managed to fit me into his schedule at relatively short notice. He is an impressive technician; anticipating the source of my problem and having the replacement part to solve it. He completed the service of the boiler efficiently leaving my kitchen as clean as when he entered. I can highly recommend him and will definitely give him a call in the future.
Friendly, reliable and reasonably priced for boiler servicing, also very helpful and quick to come out when we had an issue. Was recommended to us by a friend, and would recommend to others.
Would definitely recommend! Called up and came to help the same day. Reasonably priced. Thanks for all your help 😁
Masoud came to our rescue when we arrived home from work to find a pigeon stuck behind our gas fire. He arrived within 10 mins of calling him - was professional, polite and very knowledgable. I would highly recommend him. Overall brilliant brilliant service - thanks Masoud.
Prompt attendance at our property for a small job as part of a kitchen refurbishment. Punctual, tidy, efficient. Would use again.
Masoud came out to see us after we'd had a bad experience with another company. He explained what might be causing the problem with our boiler, then quickly diagnosed and resolved it. We appreciated knowing what to expect throughout, the communication and professionalism. Recommended!
Masood maintains our boiler excellently and is always very polite, professional and knowledgeable when he's here. Recently we called him for an emergency removal of a live pigeon from our chimney behind the gas fire. He fitted us in, coming very quickly and then was expert in his removal of the fire and the bird - who he safely released. He really saved the day, and even capped off the fire which we had been meaning to do for ages. He's a lovely guy and top pro - we thoroughly recommend him!!
Amazing service from Masoud, service with a smile which makes a pleasant change. Did a gas boiler check for me, helpful and knows his stuff. Would highly recommend this company, first class.
Professional, polite, informative about options for what I wanted. Thank you!
Quick response and good service, very professional. We will definitely use them again.
Great service from Masoud. He answered my enquiry to fix my boiler quickly and was out within a few days as it was non urgent. I would highly recommend this company. Thank you again.
Masoud came out to look at our boiler when it wouldn't hold water pressure. He fixed it and completed a service very quickly and at a very reasonable price. Excellent customer service and we are very happy with the work done. We will be using NBM again.
Very professional.
Wow! Amazing service from Masoud. He came out straight away at really short notice when our old-ish boiler had failed overnight in a cold snap. Within about an hour of calling it was diagnosed and fixed at a very reasonable price. He repaired another faulty part for free. Really great boiler technician. Recommend to anyone with a boiler! Thank you so much.
Great service.
This is the fourth year of having our annual boiler serviced by NBM. Always a great service. Lovely to deal with. Highly recommended.
I messaged Masoud via FB, he replied out of hours which I didn't expect but greatly appreciated. He helped stop a leaking boiler. A very prompt, thorough, friendly & professional service! All at a great price, will use again! Thanks again Masoud.
First class efficient service.

Cold at the top, cold at the bottom, or one room always chilly? Where a radiator is cold tells you a great deal about what is wrong.
