Ariston UK Arvostelua 1 564

I purchased an Ariston One boiler which was professionally installed, including a full system flush. Within the first 6 months the boiler began to fail, and over the past 5 years it has broken down around 10 times.

Various parts have been replaced over time, yet the boiler continues to be unreliable and, in my view, not fit for purpose. On average, we experience two breakdowns every winter—typically during the coldest periods—leaving us without heating for up to two weeks at a time. It often takes around 4 days just to get an engineer out, and repairs are frequently delayed further due to parts availability.

Customer service has been extremely disappointing. I raised complaints in 2024, 2025, and again in 2026, where we have already experienced two breakdowns this year alone.

To make matters worse, Ariston has now suspended the warranty due to not providing an invoice or receipt for the original power flush. This is despite the system having been flushed by a qualified installer at the time of installation, and again more recently. At no point was I clearly informed that documentation would be required to maintain the warranty.

While the boiler may be designed in Italy, it appears to rely on lower-cost global manufacturing and components, which raises serious concerns about long-term reliability based on my experience.

For context, my previous Worcester Bosch Greenstar boiler ran reliably for 20 years without these kinds of issues. I deeply regret switching.

My most recent interaction with Ariston customer service was particularly poor—dismissive and unhelpful, with little interest in resolving the situation.

I would strongly advise others to carefully consider their options before choosing this boiler, especially if reliability and aftercare are important to you. If you want no heating in winter for an average of two weeks, this is the boiler for you, I was told they will never replace the faulty boiler they will just keep replacing parts until the warranty runs out.

Prompt service friendly professional staff.

Great engineer very competent

Never again would get ariston boiler or get wm donnelly who they work with to do any work in my house

In France bought a heat pump boiler which costs 1800 euros. The electronic card failed after 9 months. Ariston refused to even replace the part as they say the installer didn't fit the required anti-corrosion dielectric on the hot water outlet. Maybe he didn't but that is nothing to do with the card failure. The company is dishonest and these products are low quality junk. Most of the advertised functionality never worked anyway such as the timer for switching on. So I take a big hit and junk this new kit.

Customer after care is not good. We were missing parts and tried asking a question. They replied asking for serial number. I sent photos of it. I also sent pictures of products. Heard nothing, I had to order these separately. Not really clear when buying the product. Wouldn’t recommend.

Hi, your engineer he doesn’t really good job. He’s very friendly. I am really appreciate for his service hidden accident. Thanks for your service.

Any excuse not to continue our warranty, boiler is only 4 years old, would never purchase again, awful boiler and awful company to deal with!!! Avoid!

Dealt with my enquiry/problem efficiently. It was hard to get over that it was not the thermostat, but the clock within the boiler, probably because despite my boiler not being old, new ones no longer have that system, so the person I dealt with was probably not aware of such a boiler. Despite that the problem was resolved with the help of their approved Heating Engineering firm. The person I spoke to was very helpful and pleasant.

Very nice engineer when he phoned and let me know he was on his way, he was fixing a boiler that is in one of my rental properties so I was not there and the tenant has not contacted me ! So no need is good news.. well done..

5 (all day appointments)visits to fix a problem that took 90 mins to repair, plus 1 day they didn't show up at all. We had to get through to management on the phone as this was getting ridiculous. All the while a 91 year old had a leaking boiler to deal with.
Whats their slogan, Ariston goes on and on and on..... they're not kidding
I'd never use them again

Knowledgeable polite young man. Even was happy to answer a question on his day off.

Excellent monitoring and information service backed up by annual service of heating system of similar quality from Status Heating.

Contacted Ariston regarding an issue with a newly installed boiler. They were very good in coming back to me promptly and arranging for a service partner to contact me for an inspection. Many thanks to Roberto and Gabriela for their prompt response and efficient reporting of this issue.

Brilliant service and warranty period

Pinar, was so very helpful and kind, she was competent and sorted my problem promptly. this company are getting customer care right.
I would reccommend Ariston

Prompt & pleasant receptionist when made the call.
Appointment arranged promptly with an engineer to visit & attend at a convenient time.
Pleasant & knowledgeable engineer provided sincere service and explained what was the probable cause of the problem. The engineer carried with him adequate spare parts to replace the defective part.
The only deficiency was no follow up calls to see if the problem is resolved completely satisfactorily or partially resolved or persists. In my case part of the issue is not resolved.
Thanks

Speedy efficient service. Engineer was extremely knowledgeable identified the problem and fixed in one go.

A good product at a fair price.Exceeds my expectations
