My back boiler needed replacing with a new combi. Arash came to look at the job the same day I called, talking me through the options clearly and informatively. Delays my end meant that the start date got put back several times, but Arash was never anything less than courteous and professional, answering my questions as needed. When the job was ready to start, he and his colleagues worked flat-out to finish ahead of schedule and on budget. I am very satisfied with my new heating system and would happily recommend London Heat Engineers. More...

Arash and his team have done an excellent job with our bathroom refurbishment. They were neat, tidy, efficient and accommodating and pleasant to have around. They were punctual, started the job on time and never disappeared to work on other jobs. When asked, Arash gave correct advice and did not complain if we made last minute changes. London Heat Engineers did a very professional job and I highly recommend them. Our bathroom has been transformed. More...

I have recently used London Heat Engineers on recommendation for a total bathroom refurbishment. From my first meeting to discuss my requirements through to completion Arash and his team Akbar and Masoud have shown total professionalism. The quality of their work is first class together with an ability to adapt to requests/changes without fuss. Although I initially asked Arash for help with my bathroom, he has in the process advised/helped with many other aspects - a very useful man to know!On a personal level, they are a delight to have around the house, working with minimal intrusion and always leaving everything tidy at the end of each day. I am absolutely delighted with my bathroom and have no hesitation in recommending Arash and his team. What I initially thought would be a rather uncomfortable experience has turned out to be anything but! More...

Great Service, very professional, very punctual, did the job very well, cleaned after they finished. Nobody could even tell if they were here. Because of London heat engineers ltd I have regained confidence in Plentific. We had another job done a contractor from Plentific which was a disaster. I will appreciate if Plantific does some kind of screening of their contractors. I will reccomend London Heating Engineers ltd to my friends and family More...
