  Philippa was absolutely amazing and extremely professional throughout the whole process. She truly went above and beyond to help my family secure an earlier slot for our emergency, and we are incredibly grateful for all her support and kindness. Her dedication, professionalism, and willingness to help make her a real asset to the company. We sincerely appreciate everything she did for us and wish her all the very best for the future.

  Anything above 1 star would be a criminal offence. Where do I start?!? I woke up Oct 1st 2025, to find a large puddle of water that had leaked from my boiler overnight onto my kitchen worktop. I reported it to my council who have a contract with this company. I was told someone would come within 24 hours and much to my surprise someone showed up within a few hours (only reason for 1 star). He claimed there was a blockage someone and he removed the debris, he was in and out in 15-20 mins. Within 2 hours of him leaving the boiler started to leak again. I called the council the next morning and they said someone will be out to inspect. Another person came and he said and did the exact same thing as the previous engineer; he stayed for 10 mins! Shortly after he left the boiler started to leak AGAIN, so I had to report the leak AGAIN. A days/weeks later the original engineer shows up and says he knows what the issue is, he changes a part and says I promise you it is fixed, “I will even come back tomorrow after work and knock on your door to check”. Did he show up the next day?…no! Did the boiler leak again?…Yes! So I report it for a 4th time, I’m told I have to wait a some time (several days) for an engineer to attend. Due to the leakage and not being able to catch the water properly the wood boxing around the pipe work has become damp and expanded. The engineer eventually comes says he knees exactly what the issue is but he needs to order a part and was in and out of the property in 5 mins. The job then gets rebooked and the boiler was eventually fixed and he said he would log in his report that the wood boxing would need to be replaced, somebody would contact us. So, it took 8 weeks to fix a leak and 5 visits from 4 engineers to fix. Nobody contacted me about the boxing so I had to contact the council again, because of the busy Christmas period I was told the first available date was the first full week in Jan. I booked a morning appointment and nobody showed up. I call the council and they say Thermoserv have said the engineer had an emergency but someone else will be attending. The engineer shows up an hour before I had to leave to go on the school run. He said he doesn’t have the right wood or access panel to install that day but he promises he would be back to do the work. He calls his office and puts it on loudspeaker and they booked a job for the following week. The following week comes and again the timeslot is missed. We call again, the info we received is that the engineer was stuck on another job and he is on his way. Our bell rings and it is a totally different guy from the week before. He said he only started with the company the day before and he was given the job half an hour ago. He doesn’t have the tools, the wood or any info on the job to do it today. He said he could tell how frustrated I was with everything, so he personally promised to come back when someone would be at home to do the work. We booked in for the following Tuesday and guest what?…nobody showed up! I called the council yet again, thermoserv contact me directly and say they are so sorry. The engineer was unprofessional for contacting you and that they have decided to relieve him of his duties as a result. I said I don’t want anyone to lose their job but if he is going to lose his then the others need to too! The woman claims that there is a shortage of wood from their suppliers and that is why there has an issue with the previous visits. I said so you can’t pick up a piece of plywood from b&q or wickes? She said it doesn’t work like that we don’t have accounts with them. She said we can book you in for 2 weeks time on Feb 6th. I said how do you the supply issue will be fixed. She said that’s why I’m booking it for 2 weeks, so it should be sorted by then. I said I need an appointment time that factors in the school runs and if there is any reason why you can’t attend or the engineer is delayed I need immediate communication. Well guess what? Today is Feb 6th, they missed the morning slot and nobody has called me. The worst!

  1st failed to even show with no calls whatsoever to explain. On the Wednesday. Then turn up 2 hours early without a builder and when asked to leave claims he and his pal felt threatened. A week later . Then turns up with the head of some council department and burns my carpet fails to fit valves to one radiator even though the bloke had them in his hand when the head bloke left .. Left bathroom rad leaking bedroom one not working. And a gas safety test where the boiler started whistling when turned on in the evening. Would I use them no . The bloke sat here stating he was months away from being a qualified gas engineer . Yet he fitted new rads and gas safety checked my boiler according to them. Hopefully they lose the contract with Hammersmith council. And then today he is outside and swears at me because he had to pay for the carpet he burnt.

  Do not use these guys. They don't turn up during the specified time, they don't call to let you know, when you call they don't care that they didn't turn up and then lie and say you weren't home. Disgusting organisation. Dishonesty defined.

  If their drivers are a reflection of their company, then they’re worthy of no stars. The driver of their van, LF71 OVR, nearly took my front bumper off, cutting me up on the south circular through Forest Hill as he jumped a queue of traffic and cut in - all whilst sat on his phone and shouting expletives out the window. Disgusting behaviour.

  Disgusting company, sent guy to site to ensure they got paid but left without doing anything. If you're after worthless, money grabbing and incompetence definitely hire these guys. If you want a working system go elsewhere!

  Abysmal, guy turns up...gets paid and leaves without doing a single thing. Quite happy to leave an entire building including upwards of 20 flats, vulnerable adults and child without running water. Absolute fraud company. Avoid at all costs. Conmen on site and on the phone.

  Witnessed a silver Thermoserv van do a hit and run on the a2. The car tried to stop the van however they just drove off and refused to stop!! Their actions seems to not be surprising after reading previous reviews.. avoid at all costs!

  I am leaving this review on behalf of my aunt, who lives in sheltered accommodation, along with 22 elderly residents in Whitstable, Kent. They were left with NO hot water for nearly 2 WEEKS! Thanks Thermoserv!
