Mitsubishi Electric UK Reviews 

Rubbish slow to heat the wost thing i have ever used. Always cuts out and only get little hot water for a short amount of time.

Mitsubishi Electric have just completed the annual service of the heat pump. The engineer, Robert Hausrath, did a great job. He arrived when expected then checked the entire system, reviewing the control settings and adjusting as needed. Good to have the comfort that the system is working well as we move into winter.

Excellent service from Paul the engineer who identified the problems with our Ecodan system and sorted them out. Communication with the Mitsubishi office directly is not always easy, but the engineer was worth the wait.

It is a breath of fresh air to have a truly knowledgeable engineer versed in all aspects of the system: electric, plumbing etc. Very grateful to Paul for not only fixing an issue others have failed, but also for going through a myriad of settings and optimising the system.

Steve was very thorough and explained things easily. Great service. Thanks Steve! Highly recommended.

What a great ambassador for Mitsubishi Electric UK Luke is.
Not only did he have the patience to explain EVERYTHING to a first time owner of an air source heat pump (me!), he went out of his way to make this a very enjoyable interaction which, before his visit, I had been dreading, as I was sure there would be something wrong with the system that I inherited through a house purchase. Friendly, considerate, extremely knowledgeable and an overall star. Thank you, Luke for coming such a long distance over difficult terrain with such a positive attitude. I would definitely recommend him.

It took from May when I applied to renew my service plan to 20th October for an engineer to attend. The engineer (Luke) was very knowledgeable, professional and courteous. A credit to the organisation. However the charge of nearly £500 for his attendance of less than 2 hours seems excessive to say the least given no parts or consumables were required

As I have no confidence in your Company's willingness or even ability to solve my problem, there seems little point in throwing
good money after bad.

I am totally disillusioned with all aspects of your current service, which has never been good . Your office is chaotic ,
Your engineers poorly organised and short-staffed. It would also appear that your head engineer is abrasive to put it mildly.

The Company Product is first class, The maintenance and 'customer service' is abysmal, waiting time for a real heat emergency 2 weeks for an engineer to attend with no solution effected . Avoid and keep your sanity

I have always found the engineers who visit your home to be well trained and knowledgeable however the website suggests that you will be allocated either a morning or afternoon time slot and the engineer will ring when ‘on their way’. In reality, the computerised system just allocate a day slot and the engineers sometimes don’t ring.
I have found the electronic booking system to be long winded and difficult to ring for updates. The electronic engineers report is sent out with basic notes attached or comments from the review team that aren’t always clear. I have not found the call centre staff to be particularly helpful or friendly and it is a good job that the heat pumps are efficient because there isn’t much else about dealing with Mitsubishi that is a pleasure.

Absolutely appalling service, would not recommend to anyone!
I have had a service plan for my Ecodan heating system for the past year and have not had one positive experience during this time. After a fault was discovered in December 2024 during the service, I with no contact from the company for a month unless I called and chased. It took for the system to completely fail and us to be left with no heating and hot water in January for an emergency appointment to be made to get the system running again. Shockingly, nearly a year down the line and this fault has still not been fully fixed. With long wait for appointments, no contact unless initiated by myself, parts not being ordered for the engineer visit so the full work not being able to be completed and engineers not showing up because of something in the scheduling system which meant the appointment had been cancelled without any contact telling me. I have paid extra for this work to be completed, well over £1000, and yet it has still not been completed.
I submitted a formal complaint and an urgent request for an appointment to finally complete the work over 2 weeks ago and I haven’t had a response.

The best part of being a diamond customer is always the engineer and on this occasion Steve. Excellent all round. Fantastic service. Worst is the awful and way below par customer service. Been waiting over 4 months for the service which we have tried to book so many times. Finally got a slot. Engineers didnt show and that was the fault of the customer services for apparently not completing the schedule properly. Shoddy imo. Over the last 10 years the service by the telephone team has deteriorated to poor. Their knowledge is limited. I woukd not change to anyone else because I like the peace of mind this gives me, however recommend to a Friend, ABSOLUTELY NOT. The engineers remain fantastic as was Steve today.

Paul was excellent in attending to my pump failure - replaced a failed pump under warranty and checked everything. Very insightful and recommended improved performance settings. Highly recommended.

Chris gave me a call before he arrived with a head up of timings which I really appreciated. There were a couple of minor tweaks needed, friendly, helpful and efficient.

The Engineer (Steve) provided an excellent service and was very professional and polite.

There are a number of issues with the system of booking and communication and confirmation from the Ecodan head office.

Steve Amiss came to service our heat source pump 14/10/25. He was very polite, friendly and very knowledgeable. He was able to answer any questions. He worked in a very professional manner.

We have been paying for a 3 Diamond Warranty for the past 12 years and during this time we could not fault the system and had no issues. However, this all changed on the 15th September 2025 when the boiler would not switch on, leaving us without hot water or heating. Phoned customer services at 8.05am to report the issue and since then I have heard nothing....I have phoned them multiple times to be given the same excuses "your case has been referred to the scheduling team and you have been prioritised due to being a 3 Diamond customer" The aftersales service is shockingly poor. Surely, it is fraud to take money for a service, knowing full well that you are unable to provide that service?? We have paid the full price every year and the one time our system fails, we receive no support whatsoever.
You can also tell from the way that the telephone call is handled that these representatives are fully conversed and used to receiving complaints about the service so I have no issues with them but with upper management who clearly know that there is an issue. The technicians who have previously attended to carry out the services have been absolutely brilliant and we cannot expect more from them, just a shame that the aftersales support is so poor. After doing some research ourselves (as it has now been 5 weeks since reporting the issue) we suspect we know the issue - the control panel needs to be replaced, hence why the unit keeps tripping out. This is literally a 5 minute job to replace once you have the replacement (which is readily available) Will Mitsubishi refund me the costs to replace this? After all, I think the least they can do is offer some sort of compensation for the fact that I have had to use my immersion heater which is so expensive and does contradict the whole point of having an eco system installed.
I would have recommended Mitsubishi and the heat pump to anyone who asked, now due to the service received - I would not!

Robert, the heating engineer from Mitsubishi Electric Ecodan did the annual inspection of our air source system. He was friendly, polite and answered any questions we had concerning how best to use the system. We have used this company for years and would highly recommend it.

Phil always provides an efficient service - with a friendly smile.

He had received some upsetting news regarding his health when he arrived to complete the annual service on my Air Source Heat pump. I hope all is ok and send my best wishes.

First service of our new Air Source Heating system and the engineer Steve was excellent. A detailed summary of the efficiency and potential improvements were most welcome and gave us confidence in the effectiveness of the heating for the future.

Absolute joke!! Waiting more than 2weeks for someone from Mitsubishi to book an engineer for a repair. Sent numerous emails and just getting nowhere. I would not recommend this company for your heating at all!! The guy who normally comes is very nice but just to get him booked it's a nightmare. Also the same fault with heating pump happened to numerous neighbours, probably not really quality parts were installed. At least there is a 3year guarantee on it.
