Vaillant UK Reviews 

Our Vaillant AroSTOR has broken after only 3 years and will need to be replaced. The boiler failed after a local power outage. Our heating engineer tried to fix it but couldn't. After 3 weeks of no hot water, it took a Vaillant engineer to come and set it to immersion mode to at least give us hot water again. The one star is for the engineer's service. He told me the compressor had jammed. It took a further month for a report with that information to get to our local heating engineer and I've now been told that the part is obsolete and cannot be replaced and is only covered by two years warranty anyway. I've been advised that a whole new replacement cylinder is required at our own personal cost. Vaillant, I can't tell you how disappointing this is...I expect a hot water cylinder to last longer than three years!!!

The Vaillant service engineer Tom called and right from the start he was polite and extremely through servicing my Ecotech 28 the first time that this had been done properly for several years.

He replaced gaskets and a temperature sensor then ran it up and took emission readings nothing was too much trouble.

I had availed myself of this excellent service to my Ecotech 28 through taking out insurance again with Domestic and General

In all an excellent Customer Service on one of the very best boilers available

I am in Chelmsford Essex

We’ve used Vaillant Engineers for many years to service and repair our boiler.
Another excellent service today great communication from the engineer he turned up on time and resolved a couple of minor issues during routine service. Our engineer A717 today was pleasant, helpful and efficient Top Marks !!

Undertook training on the new arotherm pro and plus range of air source heat pumps.
These things are GREAT! And the training was brilliant.
The trainer pitched the training very well for the room so everyone could understand and learn no-matter what their knowledge levels.
Shout out to Toby Collis for a brilliant session.

#508. Very helpful service today. Looked at everything and had a good attention to detail. Went out of his way to assist further. Appreciate all your help!

On boiler and very pleasant
Thankyou 10 out of 10.p

Had a Vaillant tech come out to look at an issue with cooling, and Fred was exceptional, full of good information and helped me get a grip of a new ashp system. Great service.

Engineer rang before he arrived, identified the issue, which required a pump replacement, the original pump was obsolete, so he sourced a replacement, which was difficult to fit due kitchen housing and electrics, kept me informed as he progressed and was very pleasant
What more can you ask for ?
I have used Vaillant for many years and they always deliver

I have air source pump heating. New build, been in 8 months, heating system a nightmare. Freezing in winter, during heatwave heating came on like it's never done before. For the first time in my life I'm in debt for the cost of it all, whilst still being cold in winter.
Today, Vaillant engineer #710, what a breath of fresh air. He let me explain history AND listened!!! The builders plumber kept making random adjustments whilst saying "let's try this, and see if this works" ! Not confidence building #710 answered my (many) questions with confidence and knowledge. Told me exactly what the changes he made would achieve. At last I feel heard and confident of the changes he made. Though he reassured me if things aren't quite right in winter, I can call again. What a lovely ambassador for vaillant he is. Thank you so much #710.

When I reported a problem with my hot water, I was given an appointment within a few days. The engineer identified the cause - it was a sticking valve upstairs, not the boiler at all. He made a temporary repair and I was offered an appointment the next day to have the part replaced. I call that pretty good service.

Absolute legend
Sorted all problem out with ease
Politeness and professionalism
So Pleased

#508 - Sam rang before his arrival so that knew when to expect him. He recognised the problem immediately and very efficiently carried out the repair work.

501 Ian is extremely professional in problem solving. He didn’t easy give up and try the very best to find out the cause of not having gas supplier. Finally, his professional experience helped.

#567 Fantastic service, very polite.. called prior to attending, straight to work finished the job, very thorough. Explained the issue, excellent customer service, credit to your company.

I have had a perfect customer experience from Vaillant today. Hakan, the engineer, gave me a 30 minute warning of his arrival, carried out a thorough service without leaving any mess and answered all my questions with supreme patience. That’s not the usual response to a non-technical 80 year old with a failing memory! It was a pleasure to meet such a kind, cheerful and experienced workman. Many thanks!

#412 very friendly, excellent service

These boilers are easy to use and very efficient. We've just had our 16 years old Vaillant Eco Tech boiler replaced with the newer version. Apart from routine annual safety checks we only had a couple of faults, the pressure vessel had to be replaced after about 7 years and the main circuit board developed a fault a couple of years later. Both repairs were quickly resolved at a reasonable price. During the past year the pressure has been fluctuating, going very low during the winter and very high during the summer months but the boiler continued to work as usual. After 16 years service we decided to invest in a replacement and we're very happy with the result. Thanks to HMT Plumbing Lincoln.

Commissioning Vaillant heating system,
the two engineers that commissioned our system were very professional, thorough, polite and obviously knew their job. Thank you, Matthew #566.
