Navien UK Avis 

Engineer was arrogant and appeared to be lacking in knowledge of the boiler, even after he had “training”. He strongly implied that we were somehow lying about the fault and demanded that we provide video evidence of the problem! Although the problem seemed to be fixed, it was a drawn out process that involved several visits and stressful interactions between the Navien representatives and ourselves. We just hope that we won’t need to repeat this ordeal again.

Customer Service Lady Jenna was extremely helpful and Engineer was highly competent.

Please look at spelling mistake on message to me.

Great experience with Customer Service and Rhys, the engineer who repaired our Navien combo boiler. He went over and above to fix the problem in an efficient and timely manner. Thank you to all concerned.

A bit fiddly getting to speak to the right person, but once that hurdle was cleared, they arranged for an engineer to call the next day, to replace broken part. Engineer attended, and Big Red Sticker removed.

Had boiler issue called Monday sorted Wednesday great service engineer who came out was brilliant

Really nice engineer. Sean Mcdonald was really helpful and gave good advice. Would highly recommend

Diagnosed the problems with the boiler resolved the faults and repaired the unit .⭐⭐⭐⭐⭐

We have a new oil fired Navien boiler which was installed four weeks ago. So far the boiler is running fine and the Navien app is very useful in controlling it. We had a engineer from Navien out to assist the installer and he was highly competent and sorted things out quickly.

I had an issue with my new boiler and I quite quickly got through to Navien on the phone. Someone rang me back within ten minutes. The issue was more complicated so I waited for technical support, which rang within an hour. Aubrey gave really clear instructions and the fault was corrected. Thank you so much! Brilliant service.

Had problems with NCB500 boiler losing water pressure - original installer has failed to respond to 2 x emails and calls for a fortnight. Called Navien customer care this morning - couldn’t have been more helpful ! Aubrey is a credit to you. Waiting for a call from engineer but first impressions of direct contact with Navien are excellent- only 4 stars because of boiler issue - customer service is 5+ - even had ring back service after 2 minute wait

I had an issue with my boiler and stopped working. I had to make a warranty call. They sent me one of their staff (Rhys).

he provided excellent service and was friendly and very professional staff.

Had the LCB 700 for a couple of years and it’s been nothing but trouble since the start. Constant errors from water pressure to oil pump. The engineer was apparently Navien certified, they should probably be more stringent in issuing certificates as I can’t see how they’re still in business if all products perform as bad as this one.

Had a boiler installed 2 years ago by Boxt. 2 years later, the heating recirculating valve has gone!! Rang up Navien for an engineer to fix the part. 3 days later, the part is fitted. The part is faulty. Reported this daily for 2 weeks!!! Keep getting fobbed off. Keep getting told an engineer will be out and they never turned up. Paid £25 a month for over 2 years and they STILL haven’t fixed the fault. Now going to the ombudsman to complain. Apparently Navien Tech Support people “don’t have a manager to escalate this to”. Avoid Avoid Avoid.

My father had a Navien boiler installed as he's on oil fuel, not gas (scottish highlands). There are absolutely no people who can service it nearby. It's going to cost nearly £400 for a service to get someone from the next city. Absolutely disgraceful that there's no one available to service this thing. Secondly, my father has sent two messages to Navien and been ignored both times. They take absolutely no responsibility for their products when they don't allow servicing except from an extremely limited number of people.
Now, he's looking at $4000 to change boilers.

Matthew Cundill turned up on time he was very polite and cleaned up afterwards nice chap.

Matthew Cundill was an extremely knowledgeable engineer who knows Navian Boilers inside out

We had a small job needing to be done with the boiler...
A friendly lady I spoke with on the phone organised an engineer to come out.
The engineer ( John Higham ) came out first thing Monday morning.
He rang when he was about 30 minutes away just to confirm he was nearby..
And I can honestly say the service he provided was first class....
He was extremely friendly and helpful, and sorted the job out.
And if John or anybody from Navien is reading this.. I just want to say thank you very much for the great service you provided..

Unbelievable service by Rhys the technician. An email to customer service gave a swift response, and within minutes, Rhys was ready to talk me through my issues. Problem was, I was working and wouldn't be home until after his shift finished on a Friday night with a pregnant wife and no central heating. Rhys said that wasn't any bother, and said I could call him when I got him. Rhys spent nearly 45 minutes of his Friday night, making sure my family had heating for the weekend. Outstanding human, outstanding service. Navien are lucky to have him. Rhys, Aubrey, thank you.
