United Kingdom | 04 March 2025Mantell installed a new boiler. He is competent and a hard worker. However I didn't realise he was going to be at my house until late evening. He returned the following week to install a new controller. My old one was incompatible.

United Kingdom | 09 September 2024Terrible company, quick to take your money and impossible to get hold of once they have it. Do not touch them with a barge pole, I have read the positive reviews and do not believe any of them.

United Kingdom | 10 April 2024Absolutely thrilled with the service provided by CUBESER!Not only did they efficiently fix our hot water and heating issues, but they also introduced a unique chemical solution that enhanced the performance of our boiler. The team was professional, knowledgeable, and went above and beyond to ensure everything was working perfectly fine. Highly recommend their services to anyone in need of a reliable boiler maintenance!"CUBESER is first class. They are highly skilled and run efficient business.They care about their work and customers. I was recommended to CUBESER by a few neighbours a couple of years ago and I have ceased to worry about any boiler or gas problems - I just ring and despite the work load my needs are prioritised. Thanks for the top notch service CUBESER and the chemical which saved on my energy bills.

United Kingdom | 10 April 2024Absolutely useless. No customer manners. Very rude and uses fake office responses (Amy). BE WARNED, The cubeser chemical is plain water. Nothing was added. Created a massive problem in central heating radiators. Claimed to remove dirt using a Henry hoover!!!

United Kingdom | 08 August 2023Had a Nest heating control installed...Worst ever and they absolutely refuse to return until I pay them £150 to repair their shoddy awful work! Never use them!

United Kingdom | 01 January 2023I called cubeser for a boiler and they came out straight away and done a really good job, plus they checked our radiators for free. And was nice to our cat

United Kingdom | 28 August 2022Ok service boiler working well

James Wei
United Kingdom | 20 August 2022Hired them to come out and repair the boiler. Cost £360 for one hour total. The boiler worked for less than a day before the same problem reappeared. British Gas engineer came to visit the day after and after seeing the Cubeser work report was not impressed, to say the least. Only reason I haven't given one star is that they offered me a £180 refund. Edit after reading Cubeser's reply to say that the British Gas engineer said there were multiple problems AFTER the Cubeser visit and he said he had no idea what the previous engineer even did. Ridiculous given that I've now found out that Cubeser services are double what normally is charged for emergency repairs.
