Wiser  Avis 419

5 star service !
Helped me with a Drayton product that was gifted to me, without a quible. Thank you.

I purchased Wiser a few years ago and installed it myself with some support from the Helpdesk which they helped me work out. My system has 13 iTRVs, 4 room units and 3 smart plugs so not small. As a heating controller it works very well and has saved me good money. At times the app can be a bit temperamental but as a pure heating controller it works very well and allows me to adjust the heating to our changing needs and climate. Would recommend to others.

I bought the Gen 1 thermostat kit in November last year (2025), right after returning a Tado setup that turned out to be an extremely poor experience overall. Between the attempt to push basic functionality behind subscriptions, a faulty TRV that would not pair properly, and slow, unhelpful chat-only support, I quickly lost confidence in the whole system. Wiser, by contrast, has been a far better experience from the outset.

What immediately stood out to me was how straightforward it was to get going. I installed it myself with my Ideal C26 boiler despite having no electrician or plumbing background, and it has been working reliably ever since.

My boiler happens to support the OpenTherm comms protocol, which lets Wiser do a very good job of holding a steady temperature without the boiler constantly firing hard, overshooting and creating noticeable temperature spikes. The heating feels smooth, more controlled and - I suspect - probably less stressful on the boiler as well.

Another big plus for me is that it works fully offline and (unlike tado) does not depend on any subscription. In the current smart home market that honestly counts for a lot. There’s none of that nagging feeling that features you already consider basic might suddenly be locked behind a monthly fee later on. It feels much more like you’re buying a product outright and not just renting access to it.

Reliability has also been very good in my case. I’ve never had the connection issues or pairing problems that some people describe. There have been a few occasional mobile app crashes here and there, but only very rarely and nothing serious enough to affect my overall impression of the system.

I also seem to differ from some reviewers in that I actually quite like the mobile app. I find it easy to use, scheduling is simple to set up, and I regularly use the pre-defined “Moments” to temporarily boost the temperature in a particular room outside its normal schedule. It only takes a couple of taps, so for everyday use it’s genuinely convenient.

The only thing I’ve found a bit inconsistent is the open window detection. It may work better with Gen 2 and the additional external sensors, I’m not sure, but either way it hasn’t been a major issue for me and certainly not enough to take away from an otherwise very positive experience.

Overall I’m very happy with Wiser and glad I switched. It has been reliable, easy to live with, and refreshingly free of the kind of nonsense that has become far too common in smart home products. More than anything, it feels like a system made by a company that still treats customers with respect rather than as cash cows to be squeezed for subscriptions and artificially restricted features.

We had issues with all the settings being wiped out and the router going to factory settings. this was done inadvertendly by a heating professional. I called up and spoke to John C who went out of his way to get all our settings for me to key in. Some of these I couldnt but i got help from someone else. the last bit didnt work so i called again and spoke to Josh who asked me to do something and hey presto it all worked and all our settings were there. The team are really good and ready to help in any way they can. thank you so much again.

Technical support are brilliant, so helpful. Any smart control will have its odd occassion where it can play up but on the whole this is very rare

I had a problem re setting my thermostat when my router changed. I rang Drayton Tech Support and Mike talked me through the process. Within minutes I was up and running again. Very professional, efficient and effective customer service. Thank you.

This system doesn't work as they told us they don't even have diagnostic system properly and temperature go beyond set temperature all the time. For each radiator

Very disappointing experience with Wiser.

Their advertising clearly suggests that applying for a debt consolidation loan will not impact your credit score and that a credit check will only occur if your application meets the criteria.

However, this was not my experience at all. My application was declined, yet Wiser still placed a credit enquiry on my file. As a result, my credit score dropped by around 51 points.

This is extremely concerning and contradicts the information presented to applicants during the application process.

I strongly recommend that anyone considering applying should be very cautious and fully understand the possible impact on their credit file before proceeding

This is probably the worst experience I had setting up a product, ever. The apps and hub connection is bugged and so poorly designed that I had to use multiple site and search up to the point when I realised that the app is not only horribly designed but also bugged. If I could I would change the whole system now. Avoid.

***UPDATE
After Wiser left the below reply - i thought i should let everyone know - I have already been in contact with customer support - they have been completely useless and not solved anything.

I have spent around £500 on the Drayton ‘smart’ heating system over an 18 months ago. This is without a doubt the worst purchase I’ve ever made. After paying for the initial installation and working for a few months, I have spent hours and hours and hours attempting to get this system to work properly over the last year. I have had the TRV’s randomly go offline, not turn the radiators on, and conversely turn the heating up dangerously high in my babies bedroom (running at over 27 degrees). I have tried contacting the support - this is incredibly slow taking days to reply and offering no real help to solve the issues. I was convinced to spend more money on an extender which has not fixed the issues. I wish I had never bought in to this echo system as it has bought me so much stress trying to fix. Avoid this as it’s a complete headache.

Just an unreliable system works ok for weeks then just decides not to connect. All down to the connectivity issue with app which seems to have a mind of its own. Frustrating 😡

So unnecessarily over complicated. Nothing ever sticks to the times ive set up on the schedule. I’d stick with the ones that work.

Poor Hub connection on too regular a basis. Very flaky operation via the Wiser app. probably due to poor hub Wi-Fi design. Home Wi-Wfi is super Fast and rugged throughout the home. Definate and without doubt poor design within the hub. Definate also THE worst electronic device I have ever purchased and after just over a year I'm for ripping it out and throwing in the recyle bin.

Worst system I’ve ever had to deal with. The company is just as useless as their heating system

This app and controls haven't changed for years. They have a very antiquated product now. Time for the bin. So many better ones available now at a fraction of the price

Don’t buy their thermostat kit. I recently bought one and spent countless hours trying to figure and setting up the wifi and each time it failed. I did some investigating and this appears to be a very common issue with this brand. Customer support will only give you generic IT wifi troubleshooting support, and will often “request a callback” just for them to email back to you with chatgpt answers. If you’re having issues like I did today don’t bother emailing or calling them. You’re honestly better off just returning the kit where you have bought it from as it e-waste junk. The installer who fitted the thermostat even reached out for help and they also didn’t help him. After the installer left I spent 6 hours trying to make it work and reached out to Drayton for help. My interaction ticket id: 260316. On the 4th call with them they was honest and told me that they’re not able to help as Ive just bought it and they have little to none information on their end and with all the screenshots I provided it looks like I was sold a faulty product. My advice is to check the reviews before to avoid this exact same mistake so your not out of pocket when calling a professional installer and left without no heating and time loss.

Would never use a complicated heating system which relies on WiFi ever again. My system disconnected the hub from WiFi for no reason and we couldnt get it reconnected. Was told to factory reset which lost all automation and we couldnt get it reconnected. Had to pay a boiler engineer to remove the system and go back to the old way with manual radiator valves. Would never use something which relies on WiFi to work ever again.

What a load of hard work I.T. rubbish that crashes and doesn’t work properly. Something as simple as turning the heating on has been made complicated by I.T. Wallies, avoid.

I have been calling a lot. The problem was determined to be a bad radiator thermostat. Then I provided a lot of additional information, which the agent Elie asked for. In the end, they said that the radiator thermostat was too old and we could not replace it. Although, as the advertisement says, Wiser radiator thermostats last 10-15 years. So why they ask to send photos and all other information, if they know that they change radiator thermostats, only that they have only been used a little? I felt that there was some kind of game with me and this left me with a very unpleasant impression of Wiser customer service.

I'm having problems connecting to my hub after having a new Internet contract and emailed 3 times now received a reply once and got no reply again .stick to old fashioned way less hassle .
