Joule UK Reviews 

Joule air source cylinder lasted 20 hours before the PCB blew. Spanking new install. 5 months of chasing them, they eventually reply with:

"This is a standard cylinder installed on a private supply and as such would not be covered by a manufacturer's warranty as this has been installed outside of our guidance. As a result of this we cannot arrange for an engineer to attend and resolve the issues that you've been experiencing. Please accept my apologies."

Absolutely incredible. How this company is still in existance is beyond me. It's actually criminal.

Worst heating customer care I've ever seen!
(from a 20 year plumbing and heating engineer)

This company is a joke, new built house, out of 80 houses almost 40 replaced this joule water cylinder in less then 1 year. Customare care usless. Avoid at any cost any of their products obviously poor quality.

Water cylinder leaking from PRV, manufacturer don’t want to take reaponsabilities.

Just had an air source system fitted and had to ring as I had a problem with short cycles.
I was very concerned after reading their reviews as to the service I would receive.
However it was superb !!
The guy I spoke to, Joel, was very pleasant, helpful and knowledgeable.
It seems he sorted the issue by advising me not to keep all the radiators switched off.
I’m very happy with everything so far. Any changes I’ll update 😊

Unvented cylinder less than 9 months old and not working. 2 year guarantee not worth the paper it's written on. Customer Care is a joke and needs renaming Customer NoCare. No hot water and not able to advise by phone and
no response to the email they asked me to send. Dreadful service. Go somewhere else for your heating/water appliances.

Installed air source heat pump 18 months ago - still not commissioned. Joule can always blame someone else and cover their backs. Why are builders still using this company?

We needed a new cylinder in 2017, I wanted to get a Megaflo but was persuaded to get the Joule. It was meant to last at least 25 years and has barely made 7 years. I contacted them via email and attached information pictures of the boiler and everything I had. Ellie replied ignoring everything I had already given and asked for it again. I pointed out that I have already supplied this information in the previous email and gave her answers to additional questions like it being connected to the mains. This was also ignored and I was asked to provide it again.

Considering I had sent pictures of this leaking, causing damage to our property, I was expected a less pedantic approach to a what is essentially minor details. There was no question that it is in warranty and an engineer should be sent out.

The cylinder is tight against the floor so not possible to catch the drips as I had shown in the photos I emailed but instead more time wasting from her causing more damage, very poor attitude. No customer care in sight.

I see their website is a shambles and is unavailable half the time. I would not buy anything from this company it looks like they're about to go out of business so any warranty is worthless.

Wish I could give less than one star. Indirect Unvented Storage Cylinder started leaking within 5 years. Company gave no support. Substandard product. Useless company. Do not even consider them is my advice!

I have complained until I am blue in the face about this company Joule UK. My hot water cylinder only lasted 40 months before it started leaking. No comeback because I hadn’t had it serviced, so the 25 year guarantee is useless. Is anyone interested in joining with me to take these people to court? The warranty issue is an unfair clause to get out of their duty to supply a product fit for purpose.

One star is too good for this company. Sold a faulty water cylinder, went through the warranty process to get replaced. 3 days now with no hot water. Promised delivery again and again, told lie after lie when call. Appalling customer service. AVOID THIS COMPANY

Same as everyone else here. Had plumbers fit a Stelflow cylinder - they recommended a more expensive brand but we went with Stelflow. Leaked and destroyed the ceiling below within about 8 months. Impossible to get hold of. Avoid.

Unicyl brand vented cylinder fitted in 2018, serviced in 2019 has completely disintegrated, Customer Services could not care less. Nasty cheap product. Avoid like the plague. Made by Joules UK. Who knows that you are supposed to service a cylinder every year, should be made much better. Paper thin steel, leaking through joints, Company have absolutely no interest. Other companies will not even insure these products as they are so poor.

Waited over a month for a cylinder and then they build the wrong one so go back to try again , wait another two weeks and they build the wrong one again !!! SHOCKING AVOID AND USE SOMEONE LIKE TELFORD MILES AHEAD

When a 250l water cylinder fails in less than three years and when you ask for the help the rep replies that because it hasn’t got a service history, the warranty is null and void you have to ask yourself ‘should anyone ever buy their products?’ After appalling unsympathetic and dismissive service I’d say buy from anyone but.

We moved into our house after it had been refurbished with a new hot water cylinder. Apparently, one should not expect that a basic water storage cylinder will just, you know, function. No, we were meant to read the Ts and Cs in the installation manual that we’ve never seen to say ‘service it every year’. Like you service ovens, kettles, baths, sinks every year.

The Consumer Rights act 2015 is pretty clear on ‘fit for purpose’. A qualified plumber came out and told us that the inner cylinder had failed. That’s the cylinder that is totally invisible and inaccessible. So put simply you buy from Joule at your risk. Unless you pay them to come and service something that’s in all my other houses ever has never needed servicing, because it’s a water tank, a dismissive rep will tell you that you are null and void.

Advice. Buy from a company that cares and makes decent products because Joule isn’t one of them.

Seems to me Joule have a manufacturing issue with the cylinders, like the last complaint. The fitting would not screw in & this was my 3rd in as many months. We did not get as far as fitting, as this was the first thing we tried when the cylinder turned up. Unfortunately they blamed Williams Trade for not checking this before they delivered. So we had to go back the next day at my cost to fit a Gledhill

Joule cylinder is low quality. One of the female fittings had an issue so could not be connected to. Two days of exasperating dealings with Joule saying "they could not see an issue with the thread" when clearly fitting deficient.
I purchased Joule as the most expensive and hopefully highest quality cylinder. Sadly proving not to be the case. Will get Gledhill next time

Although under warranty they will not pay out due to not having a service during 2020 and lockdown laws! No consideration for special circumstances and will try and get out of paying. Also unhelpful in trying to find suppliers to source parts needed!

Will not pay out under Warranty!

After an instalation only 3 years ago a leak started from the cylinder. It came with a 25 year warrenty but they wouldnt pay out as it needs a seperate service from the rest of the central heating every year.

They might as well offer a 1000 year warrenty they are Never going to pay out.

Supplied an Air Source Heat Pump via Heatpump Warehouse. After several hours of fault finding, it transpired that internally a plug connecting the fan to the circuit board had not been connected. At weekend so no telephone lines open so rather than leave no central heating all weekend, fixed the problem myself.
On contacting for compensation, had a very aggressive phone call suggesting I might have removed the plug myself, no apology and no thanks for saving them an engineers visit. Will never use again.

*NB So 18months after making this review, I finally get a message saying to get in touch, with no actual way of getting in touch available! Smacks to me of a company trying to look better on their appaling reviews without actually changing anything. In all liklehood it might just be a bot making an automatic reply. in the unlikely event that an actual person wrote the response, The name of the Regional Sales Manager who was aggressive, rude and accused me of lying was Adrian Thompson (Northwest and Scotland), subsequently Gary from customer services fobbed me off with contacting Samsung even though UK consumer law firmly puts the responsibility for faulty goods with the retailer!

Plummer fitted a 300l tank, worked for two years, in last year have had 3 replacement valves as water keeps leaking from cylinder overflow. Serviced as per instructions. Customer service is non existent and thoroughly disappointed at this business. All shiny on the outside rotten in middle. Go with a more prominent brand for a few more £.

After taking over the previous company which had not informed me a un vented cylinder should be serviced annually it has failed and they will not help saying the warranty is void due to the servicing not being carried out but thats hard to do if you do not know
They are unhelpful and do not have any a clue about customer service keep away from this company they are terrible
