Climastar UK Reviews 263

I’m an 83 yr old widow, needed a new electric boiler, bought a Climastar combiboiler, on the promise it would be more economical than the old one. My MONTHLY electric bill is now £500+. I live in a small well insulated bungalow.
I find the operating instructions for the boiler hard to follow, the thermostat does not seem to work, ie will not turn up down or off. Consequently the heating is on 24/7. I have asked for help on 3 occasions, more paper instructions have been sent that make little sense to me as I am not very technically minded. I daresay this is part of the problem.
May I suggest more in-depth paper instructions with plenty of pictures for elderly/lo-tech customers.
Meanwhile I need help.

Why are Climastar not answering phone calls or getting in touch? I have a faulty radiator and they are supposed to be coming out to look at it next week and now I can't get hold of them. Any body help me please

Thermostat broken, doesn’t pair! And no response from Climaster.

The company were helpful in giving a quote. They made an error in their valuation of removal of old heaters which contained asbestos, although we stated this during the survey. They helped to resolve this. One heater has a broken switch after 2 months, and I am unable to get any idea from them about how long they will take to sort it. So far waiting 2 weeks, and now no one is answering their call lines. I have emailed and left messages - this is very poor service for a system still under warranty.

Would give 0 if possible.We ordered some radiators with instalation on 14th January 2026.Unfortunatley we had to cancelled the next morning due to a medical emergency which has become very serious.
We have emailed over 6 times ,not one reply .
The couple of times I have spoke to the lady at climastar she has fobbed me off with their in meetings.Now all their telephone have been put on an answering machine system.No one answers the messages either.
David Thomas who took pleasure in telling us he is now The Boss,is not answering his phone and has put it on answering machine .
Please ,please people think twice before entering into anything with this company .They have left us shattered.My health is deteriorating and they do not have the decency to even answer. I am surprised there are so many positive reviews to be honest.Feel free to answer climastar.Update
As 28th March 2026
I will now go as far as to say this company are a set of thief's. At the time I paid a £3,130 deposit these people already knew they were in financial difficulties.They never had any intention of paying any deposit back. Even to the point at end of January where David Thomas boss at climastar as he kept telling now has his name on PURE HOME IMPROVEMENTS stoke on trent on the same business park but at no7 climastar was at no.15 all closed up .So I would say avoid here too.There is no possible contact numbers now for any of the companies he has his name on at companies house.

Workmen, Punctual ,very tidy, explained operation of thermostat, The radiators ,unique design highly efficient radiators once up to the set temperature uses very little energy to keep it there . This our sixth radiator ( expensive but we think worth the money ). Not having add any problems at the time that I wrote this review but now a stat has gone faulty and the firm is in liquidation . No phones no emails ? And probably no new stat ,I'll link it to another.

In early April 2024, Climastar fitted an inverter and batteries for me - a very slick sales process. The installation process seemed rushed with little care being taken. As examples:

a) large holes in the outside wall for the wires to go through (as expected), but all the brick dust left where it fell and no attempt made to use foam or whatever to fill the gaps around the wires - so plenty of space for cold air/mice to get in.

b) an engineer from my electricity supply company later found that one of the wires in the Henley blocks fitted by Climastar had not been screwed in properly and could simply be pulled out (a fire risk, as he said).

Having said that, the system has worked well and allowed me to take advantage of lots of cheap-rate electricity.

A couple of weeks ago, one of the batteries failed. My expectation was that I would receive support from the supplier. I was very wrong!

1) An email to Climastar asking for help - completely ignored.

2) A message sent via their website - an automated response, but nothing else.

3) A very curt "is someone actually going to answer me" email resulted in a voicemail - "It's xxx [redacted] from Climastar the electric heating company, we do the heating. If you need anything give me a call back". Bear in mind that the website message I said explained exactly what I needed, I was not looking for what was sounding very much like a sales call.

4) I wasn't able to call back, so sent a mail to xxx explaining what I needed. Once again - ignored.

Fortunately the battery supplier (who I spoke to today) has been far more helpful and is coming out to investigate the issue. They also mentioned that they will do a health inspection of the whole system - I wonder what that will say. That took one phone call to get sorted - a very different experience.

So, as others on here have said - good product, good sales process, but once Climastar has your money, you might as well not exist.

==============

Update following PureDrive's visit
---------------------------------------

The battery with the issue had completely discharged and had to be replaced. One of the other batteries was almost in the same state, but recovered. The issue was caused by the original installer (ie Climastar's electrician) using incorrect communication cables to link the batteries, leading to the batteries very slowly becoming more and more discharged.

I also contacted Climastar in Spain (the parent company) to try and get a response from Climastar UK. It was interesting to see that the Spanish directors are seemingly no longer involved with the UK company. They gave me an email address for the UK director. I have sent him two emails and have two read receipts, but no response. So, it's not just the customer service people who ignore emails, it is also the director!

Readers of these reviews should appreciate that there are high scores for installation hiding the fact that after-sales service is pretty well nonexistent. Time and again we have been promised a repair visit - once they said they were en route which was patently untrue - so we will now find help elsewhere. In our case, the installers arrived 3 hours late, fitted two radiators and a Sunamp Thermino, worked into the evening and were keen to get away, which perhaps explains why the job was not completed perfectly. Dealing with this company has been so stressful that we have regrettably given up trying.

Installer arrived on time, finished neatly, and explained controls clearly all.

Excellent from start to finish low cost radiators nathan went above and beyond to make the experience a good one and many thanks to dave.

Clean look, quick warmth, ze

Communication and service are absolutely deplorable. Avoid this company. We have been trying to receive a refund for an order placed in Sept (and we are now in December) that they failed to deliver on. The company are ignoring our emails and phonecalls. We will now be seeking legal advice.

Ben from Climastar has been in touch today (08th Dec) and is investigating our complaint. Nice to speak to someone who looks to be actively seeking a resolution. Will update once this is resolved. Thankyou so far for your assistance Ben.

Update, we are now 02nd Jan 2026 and the issue is STILL not resolved. We are still waiting for a refund. We have been passed from pillar to post with the promise of returned phonecalls that have not happened. Legal appointment made for Wednesday as we are now taking this further..I have never experienced a company who take 3.5 months to issue a refund! Absolutely disgusting!

Update 08th Feb,,still no refund, still getting fobbed off by everyone, Trading Standards are now involved and we have started the process with Small Claims Court. Not answering any calls or emails. Are these guys still trading???

Another update..
Apparently they have gone bust or going into liquidation. Interestingly the director of Climastar (appointed on 10 dec 2025) David Anthony Thomas has just been made a director as of 27 Jan 2026 of yet another company called Pure Home Improvements LTD based on the same trading estate as Climastar,,gonna start spamming/calling them from tomorrow to see if we can get some answers! Absolutely disgusting service from Climastar.

I cannot praise Climastar highly enough. My whole experience with them was excellent from start to finish. The survey to assess my needs was thorough and explained to me in detail. I chose to start with two heaters downstairs and am so pleased with them. They are very efficient, it is such a joy to have the rooms at a constant temperature, plus they look amazing. I found the office easy to contact and the fitter was very polite and professional.

Climasatar offers a supposed lifetime warranty on the stone that forms the base of their entire system and is the most expensive component of their radiators. The other components have a 2 or 3 year warranty (depending on when you bought them). This seems reassuring, making you think you'll have radiators for life, especially after a significant financial outlay, as their equipment is quite expensive. The REALITY is that when, after a few years, an internal component of the radiator breaks down (something inexpensive that should, in principle, be replaceable), it turns out the radiator can't be repaired. Their response is that those components are discontinued, and their only solution is to replace the radiator WITH A NEW ONE, requiring another outlay. You're left with the stone that had the lifetime warranty, to use as a headboard and bang your head against it every night for being so foolish as to trust these swindlers.

I was recommended Climastar through a friend . Didn’t disappoint Great service and great product

We were looking for a couple of radiators to work along side the existing heating system in a couple of rooms and chose climastar for the aesthetics and performance.
We have just had them installed and are extremely pleased. The ease and speed of installation was far better than I hoped. The guys were very professional and really accommodating with my asks. Eg they went above and beyond what I expected in terms of hiding the wires...and the end result looks amazing. Early days but the performance is just what we expected and they are working a treat.
Everyone we have dealt with at climastar have been friendly and helpful...with no hard sell and a real sense they listen to what you want and offer options and advice and dont push you to something you don't want or need.
I highly recommend them.

We’ve got our new heaters in ready for the winter, smooth process and looking to having a cosy winter with them.

We recently bought our first home and needed new radiators — we’re so glad we chose this company! From start to finish, the whole process was smooth and stress-free. Dave was absolutely amazing — he went above and beyond to help us choose the right radiators for our space, explaining everything clearly and making sure we got the best value. The delivery was on time, the quality is fantastic, and our new home feels so warm and welcoming. Couldn’t recommend them highly enough, especially if you’re a first-time buyer like us. Thanks again, Dave and the team!

Boiler broke down a week ago, taken that long to get an appointment which is in another 10 days time 2 OAP's

Heater looks modern and sleek. Heats up quickly and keeps the heat in the room for a long time when turned off. Customer Service was great, Bahar helped me to pair my radiator really easily.
