Navien UK Avis 

Very good boiler, I have one in both my houses.
I had a fault notice come up and they send an engineer out quickly, he resolved the issue while he was here.
Would certainly recommend Navien.

I had issue with my Navien boiler and was under warranty, the engineer came out and fixed my boiler great service and nice gentleman

Had an issue with my Navien Bolier , fixed under warranty, in a quick and professional manner . No issues - great service .

I had a problem with my Navien Smartplus thermostat and also had to reconnect my thermostat to my new installed broadband. I contacted Matthew Cunhill who talked me through everything, (that must have been a challenge). He was very patient and explained things really clearly and i got it sorted. I would recommend him to anyone who needs help sorting out their thermostat.

Hello I have a ncb 500 30 kw gas boiler very impressed.

Matthew Cundill(engineer) arrived on time. Very helpful and replaced parts on boiler that needed to be done. Would definitely recommend.

As a gas engineer I have been installing Navien boilers for a couple of years now and have to admit for the price you pay compared to their competitors the quality and performance of these boilers are second to none.

The trainer mat was absolutely superb at making it simple and easily understood well worth the day

We had an issue with our boiler which had only been installed in 2023.
Contacted their customer service and Genna and Chris worked together to have an engineer sent out immediately.
Within two hours he was at my address and worked till 21.30 to get my boiler up and running.
His knowledge of this boiler make was very reassuring as relatively new name to the industry.
I would highly recommend the customer service department for their reassurance and quick action resolving the problem.
Thank you Genna and Chris and all who sorted the issue. 10 out of 10

Great service from the start. I called the technical support team who guided me through what would happen and the engineer called me back the same day. Great communication, friendly, knowledgeable and sorted the issue for me. Thank you Chris.

Problem was found as soon as Matthew opened the cover which previous inspection by boiler team said differently. Very good sevice from Navien. So so pleased problem has been rectified. Many Thanks.

Contacted the Navien call centre on Wednesday as my boiler was not always firing up straight away. I had to reset it on the occasions that it didn't start first time. I was lucky enough to get an engineer appointment the following day.
The engineer was professional, knowledgeable & polite.
My Navien boiler is 4 years old now & I am very happy with it. I would definitely recommend Navien to friends & family.

Had a brand new boiler installed 2 days later it broke. Called navien they assured me would be actioned within 72hrs but most likely sooner as I was “top priority” due to having two small children, this was on Thursday, received a call Friday morning to state no one can come out to me till following Monday - left with no heating or hot water for 5 days. Told them it wasn’t good enough and they didn’t really seem to care.

Had a boiler fitted in August, already has an error code and is not working so we have no hot water, rang customer service, they were nice enough and tried to help but ultimately they told me the earliest anyone can get out to us is Tuesday next week which is simply not good enough!

The service from the initial booking agent over the phone til the engineer coming to fix our boiler was excellent. Courteous and professional...what a service should be like...well done!

Installed an ncb300 had problems with programming thermostat to boiler phoned up & Aubrey helped me connect to boiler. Now it’s on & working correctly now thank you

We had a Navien boiler installed by Boxt 3 hours after the engineers had completed the install the boiler stopped functioning. There appears to be no power going to the boiler.

I checked all obvious things such as the fuse box. And concluded the issue is somewhere in the install.

I contact Navien who made contact within an hour. Aubrey at the support team was great and understood the issue. He didn’t run through troubleshooting I said I had carried out and ensured the boiler was registered for the warranty as that had no yet been complete.

He quickly advised that they agree an engineer should attend. I received a call later that morning from the Navien customer service team to confirm my availability and that an engineer will attend today late PM.

John the engineer has since called me to confirm an eta and arrived within the time window. He was very helpful checked the install and confirmed the issue does not lie with the boiler or the gas engineers work, instead it is an issue with the electrics to the boiler which Boxt are aware and intend to replace. John also asked if it was ok to adjust some settings to make the boiler work better.

From when I have used the boiler it is functioning very well. Very impressed by the hot water and central heating output.

Phone answered quickly, easily understood questions, passed to technician, clear walk through instructions , helpful and polite. Problem resolved, excellent customer service. Thank you.

i want to thank Chris Peden, Jenna culshaw and Gareth for their excellent customer service and always helping me out in some serious situations. thank you so much team!!
