Libtek Ltd

Having spent some time researching heat pumps I found Libtek on HeatPumpMonitor.org and I was pleased to find they service North London. Libtek are one of very few installers who have a large volume of installs which facilitate public scrutiny of their performance data - 40+ installs of which 14 are currently >365 days and across many different heat pump brands. For me this spoke to their experience, confidence and credibility such that I was happy to wait for their availability to see their design. Having performed my own research and paid for a few different heat loss surveys I had a vague idea of what to expect, and the survey also provides a good opportunity to meet the installer, build an understanding of the company and therefore who your longer-term servicing relationship will be with. Alex is an excellent heating engineer and is very passionate about his specialism and squeezing efficiencies. My installation wasn't simple with the 1900s house being a terraced so all of the materials and trenching had to be taken through. That's not an easy exercise when the heat pump is 130 kilos! The wider team - Gary, Brad, Nick, Kris, Tom and Ty - were all professional and easy to speak to. The house was left tidy and I was kept informed of expectations all the way through the installation. For those considering Libtek, the team has depth across multiple brands while still maintaining high efficiencies thus demonstrating their heat engineering is sound with strong post-install support. This should mean your heating investment travels well over the life of the materials. The biggest endorsement I can provide is Libtek are currently completing an installation at my parents’ place.

Rating: ⭐⭐⭐⭐⭐ We recently had a full heating system renovation completed by Libtek, and we couldn't be happier with the results! Alex and the team installed a Kronoterm Versi Air Source Heat Pump (ASHP), a Heat Geek 300L hot water cylinder, and a castellated wet underfloor heating (UFH) system throughout our entire home (both upstairs and downstairs). From the start, Libtek went above and beyond. Navigating a large project with high stakes is stressful, but Alex was always available to answer our questions—not just about the heating, but also regarding hot & cold plumbing, MVHR, solar, and insulation. That holistic advice was hugely valuable to us. They also handled all the paperwork for the £7,500 government grant, which made the process seamless. Since the installation, the aftercare has been exceptional. The team has visited multiple times to walk us through the system, and their ability to support us remotely has been a game-changer for fine-tuning the settings. The house is now consistently warm, and the system runs efficiently and incredibly quietly—you can barely hear it inside or out! If you are looking for a company that truly cares about getting it right, I highly recommend Libtek.

Alex and his team did a brilliant job with our heat pump. Our house is nice and cosy - stays at 22 degrees and we can’t be happier. Added bonus….the hot water runs consistently and does not drop mid shower like it does with a gas boiler. It’s mid winter but the external heat pump should be fairly hidden with planting come Spring. No more gas!!!

Libtek were exceptional from start to finish. The team installed our new heat pump with real professionalism—efficient, tidy, and clearly experts at what they do. Communication was smooth throughout, and the system is performing perfectly. Couldn’t be happier with the service. Highly recommended.

Alex and his team installed our heat pump as part of a loft extension and refurbishment. After a lot of research I approached Libtek who provided the heat loss survey and design of our new system. Alex discussed options to maximise the efficiency and talked through the best set up for our needs. With any questions, Alex has been on hand to answer them and has sorted out any teething issues. His price was competitive and he's always wanting to learn more about this tech and it's application in heating our homes. Happily recommend Libtek to others wanting to move away from gas.
