 Trustindex verifies that the original source of the review is Google. I’d had various concerns about my aircon system at my flat in NW2 not working effectively, and was very relieved when Befix were able to offer a prompt service appointment. Communication in advance of the appointment was good and engineer Vahid  arrived punctually and worked carefully and thoroughly, ensuring the whole system was in good working order. He was clearly knowledgeable about all kinds of technical issues, friendly and adaptable, and I had confidence that he was attending to everything properly. I am not perhaps very familiar or up to date with what I should expect to pay for this kind of work. I think the price was probably fair - but I would advise checking in advance to make sure you are happy with the arrangement. I was left feeling relieved my system was now in good working order, and will certainly consider the company again for future work, including more ambitious projects.

 Trustindex verifies that the original source of the review is Google. Vahid was kind, professional, and incredibly good at his job. He came quickly and flexibly to west london/ Kensington area— and worked out the most economic and quickest way to help with a boiler that lost its pressure. Could not recommend this service more!

 Trustindex verifies that the original source of the review is Google. Excellent in every respect. If you need a top plumber in South East London then BeFix come highly recommended. A tricky job which had not been solved by previous professional, was immediately diagnosed by BeFix which has saved me money and time. Efficient, punctual, and reasonably priced.

 Trustindex verifies that the original source of the review is Google. Vahid was very fast to respond to my quote request and to set a time for his visit. He fixed our boiler in a very efficient and professional manner. He already had the replacement part with him beforehand which was very helpful. I would 100% recommend BeFix!
