Happy Clients for Life
Amazing service! So fast, knowledgeable, professional and very good value. We had a problem with our under floor heating and not only was Vasil able to come right away and diagnose the problem, but he also found a temporary solution for our heat while we waited for the new pump he ordered to arrive. He came back the next week and installed the new pump and now everything is working perfectly again. I would absolutely recommend him to anyone! Such a trustworthy, reliable and lovely man. We are happy clients for life!

Highly professional
Having worked with Vasil over a period of a few weeks on two projects and getting to know him and his background it became clear to me that he really stands out from the crowd. He is much more of an engineer than a boiler man which can be hit and miss. He is also a very friendly man. I must admit that initially I did not fully appreciate that as I have had many not so good experiences with tradespeople but he is the real deal. I can only recommend him. And given the quality of his work he represents very good value for money.

Excellent boiler service!
I had an excellent experience with Vasil, who came to service my boiler. He was punctual, polite, and very professional throughout the visit. Vasil took the time to explain what he was doing, carried out the service efficiently, and made sure everything was working perfectly before leaving. It’s great to find someone so knowledgeable and reliable — I’ll definitely be calling him again for future maintenance. Highly recommended!

Great work
I highly recommend Vasil of Boiler Engineer 4U. I had 5 quotes for an urgently needed new boiler and am very glad I chose him. Nothing was a problem and he installed it in a few hours. He also fixed a stuck radiator valve and as a great bonus for me he found the indoor stopcock which no other plumber had bothered to find in all my years in my house- they just turned the water off at the outside mains which was not ideal. He also will be doing the annual service. He was incredibly tidy and cleaned up after he finished. I will definitely be using him for all plumbing needs in the future.

Leaking boiler immediate response.. done and tidied up within 40 min
Reached out late evening to raise issues with a leaking boiler. Shared some images via WhatsApp and Vasil was out around ours within 20 min. The boiler leak issue was sorted and cleaned up after himself which is always appreciated. Have called him out previously, highly trusted and would recommend.

New boiler
When my boiler died, Vasil visited really quickly, recommended a new model and fitted it brilliantly. I was very happy with his polite, friendly and knowledgeable service. He even hoovered afterwards.

New gas boiler installation
I was very concerned about water leaking from my gas boiler which was over 20 years old. From the moment I contacted Vasil, I felt reassured that he would sort out the problem. He has a calm, thoughtful manner and is a really good communicator. He carefully walked me through the options. I decided to have a new gas boiler installed, because I didn’t want the inevitable ongoing costs with fixing my old one. Vasil sourced the boiler and parts and arranged an early date for he and Nasko to do the work. They did a fantastic job - really neat and professional. Vasil and Nasko worked in very cramped conditions without complaint. They tracked all the pipework around the walls perfectly, without impinging on any cupboard space. They were both totally delightful and polite, and a joy to have around – lots of lovely laughter in the home. I enjoyed hearing their banter as they worked together. They were very helpful, answering all my most basic questions. I am thrilled with the outcome. They left the place immaculate, taking every piece of rubbish away. Thank you both, I love the new boiler! And thank you, Vasil, for making this such an easy process for me. I will definitely be recommending you to my friends and look forward to using your services again in the future. Cheers, Jennie :-)

Real reliable professional
I have been calling Vasil now since 2021 years for both plumbing emergencies and boiler repairs. He has been courteous, super helpful and always resolved the problem - even remotely when my lodgers experience issues and I could not attend. He replaced my radiator valves and thermostat in one property and installed a Google Nest system in another. He can perform both advanced work and maintenance. He shows up when promised - it's nice to have someone to rely on.
