Many thanks to 820 Fred
Service & repair of Vaillant Arotherm Plus. The young gentleman Vaillant sent (820 Fred) was highly knowledgeable and explained the process as he went along (there actually wasn't much wrong with the machine in the end). A very satisfactory 5-star experience; result being that the original installers are not the ones we’re going to use for servicing in the future, but rather stay with Vaillant direct. Many thanks!

Planned obsolescence- Boiler breaks down just before guarantee expires yet I still get fobbed off from a repair.
24th June 2026:
Built-in planned obsolescence could not be more evident after my Protec 28 Pro model broke down literally weeks before my 7 year guarantee expires. Fault codes 28 followed by 29, ignition fault -despite power, pressure and gas supply to thr boiler being present. This does not inspire much confidence in Vaillant and destroys what little trust that still remained with the company. Regardless, my request to have the boiler repaired was met with frustration. Apparently it was not registered. If this was true, how did the company know so much about me, my personal details, address, phone number, boiler model and when it was installed when I called them. I never provided that information. After checking my chat with my gas engineer, it turned out he registered my boiler with Vaillant and this was confirmed in the chat as well as by the fact that Vaillant had all my boiler details. So stage 2 of their attempt to excuse themselves from their guarantee obligations: They said my engineer needed to do it through their My Rewards process using a Vaillant app. This was not a requirement according to their website which clearly stated to qualify for 7 years guarantee, it simply needed to be fitted by a CORGI registered engineer. Excuse after excuse. This was the third Vaillant boiler to breakdown with me. I am a landlord and have then at my properties including at my own house. I am now considering litigation. All future boilers will now be replaced by Worcester Bosch after this experience. Watch this space as I hope to report back on the results of my litigation.
Update: 2nd July 2026:
Vaillant have responded to my review as you can see below. However, their response is disingenuous. I HAD already emailed them but got no response. It is clear to me then, that they only reply to appear to the public that they care, when this could not be further from the truth.
Also, I had to call out my own engineer who charged me £100 to replace an ignition part. This is such a small cost for Vaillant to be destroying their reputation over. Vaillant had engineers in the area and could so easily have remedied this but they chose not to. As a matter of principle, I will still be continuing with my litigation and will report here, on its progress and outcome.

Thank you for your review, we’re sorry to hear about your boiler and the guarantee. The boiler extended guarantee must be registered by a myREWARDS Loyalty Club registered installer within 30 days of installing the appliance on the myREWARDS installer portal. As you have advised your installer did register the guarantee with us, please email us at reviews@vaillant.co.uk with the installation address and boiler serial number this relates to, so that we can look into this with our customer care team.
We look forward to hearing from you.
Kind regards, Vaillant

Ryan (260) from Vaillant Service
Ryan - Engineer No 260 did an excellent job. He ran up and down stairs in boiling hot weather making sure he left nothing unchecked. He even managed to check the flue which is in a very awkward part of the roof. He was clearly a perfectionist, but at the same time very pleasant and polite. He was also very patient with my extremely yappy dog! Would highly recommend.
