Did a great job fixing our dated pipes, quick and efficient worker.
Outstanding job installing our new Vaillant boiler today, completed by Vasil and his team. Really professional approach from start to finish and our property was left spotless after the installation. Would definitely recommend their services.
Thanks to Vasil and his quick and outstanding service my boiler was fixed in a period of a hour. He come on time ( Actually 30 minutes earlier ), was professional and detailed, he cleaned afterwards ( Not really so usual like we all know ) and was in contact with me asking for updates regarding issue which he fixed. Definitely I can recommend him and his service to anyone looking for boiler engineer around SW London. 🌟 🌟🌟🌟🌟
Yes very efficient, tidy and reliable. Replace central heating pump, flush the system and service the boiler. Happy to recommend.
Fast, professional and gave good advice
