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![]()

Choosing the right installer is crucial for maximizing the benefits of your smart heating controls. While many electricians or general plumbers offer installation, Befix brings the focused expertise of dedicated heating specialists. We understand the intricacies of London's diverse housing stock and how different heating systems (combi boilers, system boilers with tanks, underfloor heating) interact with smart technology.
Our Gas Safe registered engineers ensure not only that your Nest, Hive, or other smart thermostat is correctly wired but that it communicates effectively with your boiler and controls your heating system efficiently. We specialize in seamless integration, configuring the system for optimal performance and providing clear guidance on using all its features.
Get in Touch for Expert InstallationWe discuss your needs, existing system, and preferred smart thermostat (Nest, Hive, etc.) to ensure compatibility and suitability.
Our engineer evaluates your current heating setup and wiring to plan the installation efficiently.
We provide a clear, upfront quote detailing the work involved, with no hidden costs.
Our qualified engineer installs the smart thermostat, hub (if required), and components with minimal disruption.
We help you install and configure the app, connect your thermostat to Wi-Fi, and provide a full demo on using your new system.
The price of the smart thermostat itself (Nest, Hive, etc.) can vary depending on the model. We offer a range of options to fit your needs and budget.
If your existing heating system is compatible with smart controls, the installation process will be straightforward. For older systems or additional wiring, the cost may vary.
If modifications to your existing wiring are required to ensure compatibility with the smart thermostat, this will be reflected in the final cost.
Replacing an old thermostat with a compatible smart model is typically quicker and less expensive. We’ll provide a tailored quote based on your current setup.
Most modern heating systems (including combi, system, and conventional boilers) are compatible with leading smart thermostats. However, compatibility can depend on the specific wiring and setup. Our engineers will assess your system during the consultation to confirm compatibility before installation.
A standard installation, replacing an existing thermostat, usually takes between 1 to 3 hours. More complex installations, perhaps requiring new wiring or integration with zoned systems, may take longer. We will provide a time estimate with your quote.
Yes, a stable home Wi-Fi network is required to enable the 'smart' features, such as remote control via the app, software updates, and communication between devices (like the thermostat and hub/heat link).
While some basic installations might seem straightforward, smart thermostats interact directly with your heating system and mains electricity. For safety, correct operation, and to ensure warranty validity, we strongly recommend professional installation by qualified engineers like those at Befix, especially given the complexities of different heating systems.
Savings vary depending on your lifestyle, home insulation, and how effectively you use the smart features. Manufacturers like Nest and Hive suggest potential savings of 10-15% or more on heating bills, primarily by reducing wasted energy when you're away or asleep, and by optimizing heating schedules.
Your smart thermostat will typically continue to function as a basic thermostat, maintaining your heating schedule based on its last known settings or allowing manual adjustments directly on the device. However, remote control via the app will be unavailable until the internet connection is restored.
While Nest and Hive are the most popular choices, we have experience with various smart heating control systems. Please discuss your preferred brand with us during the consultation, and we can advise on installation.
We provide a full demonstration on how to use your new system and app. Our installations are backed by our workmanship guarantee, and we are available to answer any follow-up questions you may have about operating your smart heating controls.
