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.Posted on 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!Posted on 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!Posted on Google![]()

Covers inspection of up to 3 gas appliances
A: While not a legal requirement for homeowners living in their own property, it is highly recommended to have an annual gas safety check for your own peace of mind and safety. Faulty gas appliances can be extremely dangerous.!
A: Landlords in the UK are legally required to have a gas safety check performed on their rental properties every 12 months. A copy of the valid certificate must be provided to existing tenants within 28 days of the check and to new tenants before they move in.
A: Only engineers who are registered with the Gas Safe Register are legally allowed to carry out gas work and issue Gas Safety Certificates in the UK. Always ask to see their Gas Safe ID card.
A: The engineer will check all gas appliances owned by the landlord (or homeowner if requested), which usually includes gas boilers, gas fires, gas cookers/hobs, and gas water heaters. They also check the visible gas pipework and flues.
A: If an appliance is deemed unsafe, the engineer will explain the problem. Depending on the severity, they might issue a warning notice or, if it's 'Immediately Dangerous', they will disconnect the appliance with your permission to make it safe. The certificate cannot be fully issued until the necessary repairs are completed. BeFix can provide a quote for any required remedial work.
A: A typical check for a standard property with a boiler, hob, and/or fire usually takes around 30-60 minutes, but this can vary depending on the number and type of appliances and the complexity of the installation.
A: Someone over 18 needs to be present to grant the engineer access to the property and the gas meter. For landlords, this could be the tenant, provided they are aware and agree.
A: A Gas Safety Certificate (CP12) is valid for 12 months from the date of issue.
