Just had to ring them because they booked a £400 service visit without any consent. Had nothing but issues, warranty is worthless. It doesn't cover labour or parts!

****UPDATE***** As Kingspan reached out following this review I did what they asked and contacted them on same date. As expected I've heard nothing further. And still awaiting refund 26/2/24 *****
If I could leave 0 stars I would. We are small rural housing estate (18 residents) we have platinum contract. Alarm for bio disc first went off on 26 December. Tried contacting kingspan but closed for holidays and weekend no emergency contact. Sewage was coming into a residents house. We finally made contact with our account mgr just after new year by which time we had to call out a independent company to bring in a pump. Kingspan quoted us £2300 for a repair they hadn't even came out to see it was based on photos we sent. We had to pay upfront in order to get them to agree to come however they gave us a 2 week date for engineer arrival. We had to pay £900 to get the independent company back as the sewage was coming up through a residents sink. Kingspan sent parts for a repair they still hadn't seen. But as we'd fixed the problem parts not needed. We are still chasing our refund. Apparently we can't get refund until parts returned and we need to pay to return parts which were not even needed in first place. We are now £2400 in arrears waiting to be refunded. Our account mgr has not been helpful and I can't get them to send their complaints procedure or the name of senior mgr to complain to.

Having purchased a basement pump from Kingspan i was then approached to take out a service contract with them. This contract was not cheap, was more than others but was told that if it is serviced by the manufacturer i have a warranty. Only in May 2023 was i approached to renew it again and the proposal for the scheme said - validates your warranty by servicing in line with manufacturer guidelines.
Guess what - now it needs repair work carried out they say the contract does not cover warranty work. Not sure how a large corporate entity gets away with being misleading in its approach to clients.

Installed Kinspan Connect Oil Sensor last year. It has been nothing but trouble since I install it. I have given up on this product and am going back to a manual gauge. Do not waste your money on this product.

Never their fault with any problem that arrises forklift drivers need retraining as they can't move a pallet without breaking it. If only that they had payed as much attention to the safety of people lives than they do to a cracked pallet would be a start

I have a Klargester installed since 2000. It worked fine for about five years. I got it emptied every year. Then belts started to go. Got them replaced. Then the motor went got that replaced. Then the pump went which flooded the motor and I replaced belts, motor and pump. Next the bearings went, got those replaced. I spent about €4000 on it over the years. The bearings have seized again and I replaced another pump. I am going to remove it and will not replace it with another Klargester.

My builders installed an sewage treatment plant in 2021 and I paid Kingspan for a commissioning visit and Gold warranty. There was a significant installation cost so I wanted to ensure everything was right.
Maybe I was naive in what I signed up for but it missed the large expense of the annual service visits to maintain the warranty - £323 this year!
At least I'm covered I thought - but NO. Their T&C have ensured that I've paid in full or part for the issues that have arisen. Pump failure and an issue with the sump separating from the frame. These I believe are issues with their design not how I've operated the system, but are not fully covered by the warranty.
Since installation (2021) it has cost me over £900 for the warranty and servicing and a further £530+ pound to fix issues. There still the cost of emptying on top of that.
The engineers who have come have been good, polite and knowledgeable. The customer service has been mixed sometime responsive and sometime slow and initially trying to push add ons to the system.
I have had multiple emails with customer service and have received apologies if they did not provide sufficient explanations but the one star is because I am still left feeling cheated at tie in to high cost for maintaining a system that has flaws that are not fully covered by an expensive warranty.
I chose Kingspan expecting a quality design and a company I could trust but my experience has not supported this.

After £4,000 paid to them to fix a sewage pumping station and almost 3 weeks they will be leaving us over Christmas with no working system. I have found a solicitor to help me get my money back. They are disgraceful! So after my last review I thought things may improve but I stead they are worse. Oh we lost your £2,500 pumps but it’s not us it’s a courier! Well I paid them not the courier so I hold them accountable. The engineer turned up 4 hours early and left before he was supposed to turn up. Merry Christmas Kingspan! I will not be able to shower, wash up, do my laundry. Or anything that requires me to use my water system. Never use them!!!!!

Poor quality product (immersion heater) and shockingly poor customer service.
I have had a response today but the ‘resolving the situation’ is not making a great deal of difference. I still have no hot water and no idea when this will be resolved. It hinges on a dispute about water quality.

My rain water pump has failed 3 times in 10 months. They swap it over and it just fails again and again. Avoid this junk.

i purchased a kingspan klargester in 2019 . It was installed by a reputable builder and they followed all the installation instructions regarding bedding and surround of the tank. Some moths ago during a service visit from kinsspan i noticed the water level had fallen. The service engineer suggested i invetigate and therefore i arranged for a pump out of the tank. At that point i could see that the tank had split on a circular joint of the vessel. I contacted kingspan and they asked for photos which i sent. They were completly uninterested and just said it was not thier fault. I suggested that the shoud at least investicage why the joint had failed. I asked the stockist who i bought the klargester from to see if he could get some response to at least investigate and he said he was not listened to at all and they were not interested. This will cost around £10,000 to replace.

I purchased a 1250 litre Titan oil tank 6 years ago. I went to have a delivery of oil and was refused as it was spit along the top, the split was too deep they said to risk it. Considering this tank, yes it was single skin, but surely for £1300 it should have lasted longer than 6 years. The oil tank previously at the cottage was metal and lasted me 10 years and the house had been empty for 5 prior to that. When I was getting quotes not one company quoted a Titan, as they said they are prone to splitting. Your warned.

My Kingspan Klargester was installed in 2019. In the last year there have been recurrent problems with flashing warning lights and recently the paddles stopped turning.
So I switched from a local Hampshire company who had been servicing the Klargester to Kingspan and took out an annual contract with them at the beginning of Nov 23.
I am now regretting this decision bitterly. The Klargester has been non-functional for a week and will not be functioning for at least another week.
I have had to have the tank emptied early in case an overflow happens. Also the smell is not too pleasant.
I'm not going to complain - rather to state aspects of Kingspan's business model which render them ineffectual as a provider of service:
When requesting a service call out a date and time will not be given in advance, in my case a text was sent on the day of the visit.
Admin staff frequently (according to their engineer) send engineers to incorrect addresses. In my case they sent their engineer from Southampton to the invoice address in East Sussex rather than to the address where the Klargester was sited only 10 miles from Southampton, poor man!
This visit was invoiced for and a requested credit note for the invoice has not been received.
The Klargester was finally serviced and the motor replaced. The engineer discovered a further faulty part. The Klargester stopped working immediately after he left.
He recorded the faulty part in the service record which I received 2 days later but Kingspan had not arranged a further visit although there was a fault.
I then arranged a further service visit, or so I thought! But no! A further call established that no visit had been arranged as I had not paid for it. Unfortunately I was not informed that I had to do this.
Kingspan is the only company I have heard of that requires pre payment for all visits and parts for relatively small sums. This model seems unacceptable given the environmental implications of faults with their equipment. I suspect this is because a third party is doing the servicing?
I can hardly bear to write this but only do it as perhaps it will give other customers comfort to know that they are not alone.

My sewage pumping station failed early Saturday Morning, I have a service contract with Kingspan, one yearly service and breakdowns. To my horror was met with a very rude call agent who told me off for interrupting him, we are both in our mid 70s and me a disabled person, we have no toilet facilities and left abandoned and told to call the office Monday. The call agent said there is nothing more he could do for us with our overflowing sewage pumping station, absolutely no care or empathy we are at our whits end at what to do?? Have to apologise to Kingspan on looking at my terms and conditions I do not have a breakdown contract, and contacting there office this morning are moving very swiftly to to sort out all my problems.

Absolut scam.
I hae purchased a water cylinder from Kingspan that after 1 year of use only it started leaking boiling hot water and they refused to put this under warranty.
Scammers! Avoid them like plague

No reply from Technical Services after several attempts by my builder & me to our contact by phone, email and webform messages.
Need technical advice urgently re. Installation solution for 75mm PIR boards fitted on extension currently being built.
Below is only response we've had (i.e. an Out of Office reply):
"Thank you for your General Technical enquiry.
A member of our team will be in touch as soon as possible.
Kind regards,
Kingspan Technical"
Edit: After actioning the response from Kingspan's reply to this TrustPilot review, guess what...still no response from Kingspan. Absolutely, no courtesy by this firm.

We are plumbing company who purchased a water tank from Kingspan which was installed at a brand new home build in May. Paint peeling off less than 2 months later. This issue was first raised with Kingspan on 5th July. Followed up by email on 10 July. 10 July replied asking for photos, they were sent to Kingspan the same day. I called Kingspan on 12 July they said they would raise a ticket to have a technician fix it, they would call me to schedule this. I called again on 14 July and finally managed to have an apt scheduled for 31 July first thing in the morning. We scheduled on of our plumbers to be onsite for this appointment. Kingspan then changed the appointment the day before. We rescheduled our plumbers appointments. On the day of the appointment, Kingspan called to cancel. They wanted to reschedule for 4-6 weeks away! We said this was unacceptable and got an appointment booked for 16 August. Technicians showed up and were getting ready for the job so our plumber left them to it. We then get a call from Kingspan that they did not bring the right coloured paint with them. The paint colour they would have on their records from our order, and the paint colour that was shown in our photos. Kingspan now want us to wait until 28 Sept for them to try again. This will be 12 WEEKS from the date the problem was initially raised! Kingspan is not returning our phone calls. All along the way they have spoken of the repair needed as a "valve replacement", "outlet issue" and all manner of other unrelated things. Our call today to again follow up on our request for a call back from Betty, we were fobbed off and HUNG UP ON. The paint is peeling. It should not be this difficult. Your customer service team are completely incompetent. I am now making a report to the ACCC.

This company charged me £254 for a service telling me I'd have plenty of piping hot water thereafter. I didn't. It continued to decline in efficiency until all I had was tepid water. The lady with the Polish name whose title is, confusingly, Accounts Manager, but seems to be in charge of Customer Service, said she'd ask the engineer to call me. He never did. I asked for instructions as to how the system worked and, in particular, the programmer, but I didn't receive any. I wrote a letter complaining about my experience and how the company had and was continuing to fail me. The only reply was verbal and vague and I was told my complaint would be investigated, but I never heard any more about it. I was offered an engineer's visit but when I asked how long it would take I received no response and was not willing to live any longer with my tepid water, so
in the end, I found a very good local man to come and fix my unvented cylinder. I thought, in the circumstances, Kingspan should reimburse me but they have refused.

thank you for your reply below. Sadly, predictably, i had already rung your customer service team last week who said they would get back later that day. They never did. I was not surprised as the company does not do what it says on the can in any respect. So I had to call out my own trusted plumber over the weekend to make my previously functioning system safe and workable again.
FOLLOW UP: Kingspan have now refunded me in full for their visit. I guess things happen and they did the honourable thing.
