Navien UK Avis 

Prompt response and trustworthy warranty backup. Only real problem was boiler failure occurred at weekend outwith customer service hours so we were unable to arrange repair until it opened on the Monday. Initial engineer was going to be another 4 days but on myself contacting and suggesting another local company that could attend next day customer services were happy to sanction this. Engineer that attended promptly as arranged found defect and replaced part on the spot. Dropped a star because of myself having to look for the quicker attendance in place of the Navien engineer instead of them using a local approved.

Not impressed with the boiler or where it is installed - in the loft - as it failed several times shortly after we moved in. It was only just over 12 months from new so we had two engineers visit FOC but it failed again soon after. A third engineer - this time from Navien - turned up and correctly diagnosed and replaced a faulty valve. I am an engineer and to say this item was flimsy is no exaggeration no wonder it failed after such a short time after installation. The only good thing I have to say about Navien - hence the 4 stars- is that their engineer was good.

He came and did a good work even though he seemed to be on the run and I didn't like the fact that when he was done.He didn't even checked the water and boiler but overall it was alright

Guy came out to boiler from Navienne. Checked over boiler and found it to be ok. The problem was no oil feed. No charge was made for call out under guarantee which was a relief. The was polite and helpful.

The engineer, Mathew, turned up promptly on time and did the work in very professional and customer focused manner. It has become rare to recieve good customer service from engineers nowadays so to be able to meet someone like Mathew who is very much customer focused is a good experience. 5 stars for the engineer..

I reported that I had no hot water at 12 noon lunchtime and by 3.30pm the same day my boiler was fixed. The engineer John Higham was very nice and explained what the problem was.

We had 2 engineers come to repair our boiler. First one thought it was fixed but a couple of days later the same problem came back. Got another engineer out and thankfully 🤞🤞 we haven't had a problem again ( boiler was dropping pressure). Both engineers were very professional and polite.

Incredibly fuel efficient (our’s is oil fed)

Though we have had cocerns with one of their approved service engineers (didn't do a proper service leading to problems ) Navien themselves are extremely understanding and responsive.
We have two Navien boilers and would recommend them

Great service today by
MATHEW CUNDILL.

I contacted Matthew Cundill at Navien he went above and beyond to sort my problem, The service was fabulous this is a great combi boiler [NCB 300] for the money

Whilst our boiler was being serviced engineer noticed a damage part, contacted Navien to let them know. Within a week received a phone call from engineer to to give us time of arrival to carry out repair, the engineer was polite and courteous, and most professional. As a retired engineer myself I was interested in asking a few questions, the young engineer had no problem explaining what he was doing. This is our first experience with a Navien boiler and so far cannot fault the speed and efficiency in which they dealt with the issue. First class Navien service and the engineer Shawn.

Quick response by Zeshan to an incorrect boiler setting by the installer. Problem sorted over the phone.

Thank you John Higham
You came out today and fixed the boiler in a speedy professional manner.
A credit to Navien
Great guy

On completion of fitting a ncb 500 37kw boiler, the boiler pump was not working, the engineer Sean was able to come out that day late afternoon to change the pump over and get the boiler working, first class service couldn't ask for any better.

Had a training day on Navien products!

Matthew Cundill was very knowledgeable and we took away a lot.

Aubrey, from the customer service department, was very helpful, when I rang and said that my Navien oil boiler had a problem under warranty, and he said they would get the part fitted for me.

Had a visit from Stephen
What a lovely engineer pleasure to deal with he also had taken the time to educate me which has help with my energy consumption through navien innovative technology

Thanks Stephen

Excellent service, engineer very knowledgeable and friendly. Fitted new PCB and the boiler was back to normal working order.

Aubrey from customer care and the others I have been dealing with have been outstanding. Our boiler was never properly registered by the independent installer and now we have an issue three years later it is a problem of course. Aubrey has gone over and above with advice and support and has properly registered it and is organising a Navien UK engineer to come and repair. Fantastic support!
