Top notch service

I had a heat pump installed in February and last week I had issue with my hot water. I phoned Tom at Trianco and it was because I had changed some settings in error he managed to change some settings online and got everything up and running again for us. Top notch service!

Activair 15kw heat pumps dont work, zero customer support

I have two Activair 15kW heat pumps installed in May 2025, and they have never worked properly. For example, the system heats the hot water as expected, but then every 90 minutes it circulates cold water from outside, stripping all the heat out of the hot water cylinder. Within about 12 hours, the water is cold again. There are other issues that break features such as weather compensation.
The real issue is the complete lack of support from Trianco. They refuse to speak to me directly and hide behind “contractual reasons,” insisting I go through the installer. After about nine months, my installer managed to arrange a Trianco engineer site visit. The engineer saw the faults for himself, and confirmed the problems were real. He said he would produce a report for the installer with steps to remedy.
Nothing happened.
When I asked for a copy of the report, Trianco refused to provide it. It’s obvious why—because they’ve effectively decided to do nothing. So I’m left with £15,000 heat pumps that don’t work and a 10-year warranty that is not worth the paper it is written on.
Avoid this company. The product doesn’t perform, and the customer support is non-existent. If you do go with Trianco, be prepared for a long, frustrating fight to get them to take responsibility. I don’t know how long a fight it will be as I have not made much progress so far.

We strongly dispute the claims made in this review and would like to provide clarification based on our records.

The heat pumps were purchased and installed by an installer independent of Trianco on 1st August 2025.

Trianco has been actively involved in supporting this installation since early in its lifecycle. Our engineer first attended site on 23/10/2025, where a full report—along with supporting photographic and video evidence—was compiled and issued to the installer, including recommendations to improve system performance. A further visit took place on 03/03/2026, with additional recommendations again provided. To date, these recommended changes have not been carried out by the installer. In addition to site visits, our engineer has provided extensive support, including 12 phone calls totalling approximately 1 hour and 45 minutes, as well as over 90 WhatsApp messages, several video calls and numerous emails offering technical guidance and troubleshooting assistance.

During both site visits, significant installation issues were identified. These included incorrect pipework sizing (35mm flow / 28mm return) and the placement of the heat pumps within a temporary lean-to structure, which restricts airflow and creates a localised microclimate. This environment directly impacts system performance and has led to recommendations such as relocating the units and repositioning the weather compensation probes. These matters relate to installation quality rather than product fault.

All findings and recommended remedial actions have been clearly documented and provided to the installer, who is responsible for carrying out the necessary corrective work. While the equipment was installed for you free under an ECO scheme, we would like to emphasise that all customers receive the same level of technical support regardless of how the product was supplied.

We also note that you attempted to contact our engineer directly on several occasions including while he was on annual leave. Our standard support process is via our head office technical team, which remains available during normal working hours. Our Engineer continues to reiterate to you that the issues identified relate to the installation and should be addressed with the installer but you have continued to raise issues with Trianco rather than address with the installer.

We remain committed to supporting a resolution and will continue to assist the installer with clear technical guidance. However, the issues identified must be addressed at installation level for the system to operate correctly.

Absolutely awful customer service.

Absolutely awful customer service.
After having a Trianco air source heat pump installed, it drops off the 4g network, rendering operation when I'm away from home impossible.
After contacting the technical team, I felt like I'd been spoken to by a brain dead moron. Telling me "Trianco aren't responsible for my 4g connection"
I've asked why the heat pump hadn't been connected via WiFi. The question must be too difficult or embarrassing for them to answer, or they just couldn't think of an excuse.
In all I'm bitterly disappointed. Mainly with the poor amateurish off hand response from the technical department all the way up to the managing director.
My advice would be do your research before parting with large sums of money. Trianco are not trustworthy or professional. Steer well clear.

Thanks for the reply.
And I agree, you offered a wifi module. You stated this was an additional cost, not only to purchase, but that it would require installation by an electrician.
Furthermore, what reviews I leave for bad service or products are entirely up to me.
I tend not to pat companies on the back with nice reviews when all they are doing is fulfilling their obligations.
What I do, and will continue to do, is slate companies and business that let me down or provide lack lustre workmanship, after sales or products.
I then hope others won't fall into the same traps as myself.
As for abuse. You seem a little over sensitive on my review.
I, like many, will react badly after being spoken in a manner inferring they are an idiot. Maybe I'm at fault for venting my frustration. But never mind. We all have our faults don't we.
At the end of the day, Trianco are clearly in denial. Still stating the obvious that they aren't responsible for the 4g network.
I don't know who wrote the response but they need to think before repeating their corporate drivel.

We’re sorry to hear about your frustration with the 4G signal. Unfortunately, mobile network coverage is outside of our control. We did investigate the matter and found that, over a 14-month period, there was only a brief interruption lasting four days.

In response to your concerns, we offered you the option of purchasing a Wi-Fi solution to help improve connectivity, but this option was declined.

We understand that technical issues can be frustrating. However, we are committed to maintaining a respectful environment for both our customers and staff, and we do not tolerate abusive behaviour in any form.

We also note from your review history that you have only ever left one star ratings for other companies. While we respect every customer’s right to share their experience, we remain confident that we acted appropriately and made reasonable efforts to assist.

Quality control in their factory or…

Quality control in their factory or warehouse is severely lacking. I ordered an inrared panel. It arrived smashed. No damage to the packaging at all. To be fair they provided a replacement quickly (hence the second star) but this arrived dented. There was a penetration through the box where the dent is but no damage on the outer packaging - so the damage must have occurred before it left their warehouse. Twice was enough - i asked for a refund that time.

I'm afraid this was due to an issue with the courier. All our products leave our premises in perfect condition but sometimes get damaged in transit.

Trianco 15 KW Air Source Heat Pump

I have a Trianco 15 KW air source heat pump which I am really pleased with. Fergal at Trianco has been very helpful (and very patient) in explaining how to adjust the settings to get my heat pump working more efficiently. Would definitely recommend.

Awful customer service

Need new glass and rope for my fire, contacted their customer service to question the size needed as their site doesn't give details and there's two different size ropes on the door, got a reply back with just a link to the site so they'd clearly not read the email, replied again saying their site doesn't give the details, nothing back, tried for the third time to get a response, still nothing, avoid if you can.

What a terrible company

What a terrible company, take your money for an inferior product, arrived with no fittings, no mention in instructions that you also need flow restrictor valve and woe betide you if you dare phone customer service as your treated and spoken to as if you're a total imbecile. Buy any make but avoid this company like the plague.

Dear Mike,

Thank you for taking the time to leave a review.

We dispute that our products are inferior, we have thousands of happy customers. On the third party site which you purchased our product the installation manual is available to download which explains how to install the boiler and what fittings are required.

You were able to purchase the fittings in question as an optional extra but declined to do so.

We are sorry you are unhappy with your experience on this occasion, if there is anything we can help with in the future please email info@trianco.co.uk

Kind regards,
Trianco

I had a electric new Trianco boiler…

I had a electric new Trianco boiler installed 8 years ago, after 4 years the circuit board failed and I had to get a new one. Now after 8 years it has gone again. I rang the company and was told it would be £300.00 for another.
I explained to Trianco this is the second time in 8 years the boilers circuit board has failed. I have a tenant without heating. They offered to do a diagnostic if i send it in and if it’s faulty may provide a circuit board at a discount. My issue is I don’t have the time to wait 2 weeks as it is 23 12 2022. My tenant needs heating now.
If i did get another circuit board how likely is to fail again.
I make it my priority to only purchase from companies that provide good customer and after sale service.
I have decided to cut my loses and buy a new boiler, but definitely not from Trianco.

Impartial expert advice

I rang Trianco to ask about replacing a gas boiler with an electric boiler. The advisor explained the technical issues involved patiently and thoroughly. He gave me information which will enable me to make an informed decision, and assured me of future help. I will certainly go back to Trianco if we decide to purchase. It's not easy to find a company that is so helpful.

Excellent--

Over the last few days I spoke to both the parts and technical departments regarding a very old boiler that's needing some attention.

Both departments were so helpful and willing to assist me.

Customer service at its best.

Many thanks

Trianco Service is Exceptional

Having a customer with a aging oil boiler requiring spares parts, I rang Trianco with my parts needs, not only were they able to supply the parts, the service was exceptionally speedy.
I might add the original part sent were not compatible with the aging unit, on calling they made the parts and replaced without quibble and again exceptionally fast.
In particular Peter in the parts department was helpful, knowledgeable and true to his work.
