We found Libtek via Heat Geek. After a detailed heat loss survey, Alex and his team installed a Vaillant Arotherm air source heat pump (ASHP) system in December 2023 with a bespoke Newark cylinder and Level 3 heat pump monitoring bundle from OpenEnergyMonitor. The system has been performing brilliantly, regularly achieving COPs of 4/5. We would have no hesitation in recommending Alex/Libtek.

Alex Winters (Libtek) did a great job of installing a 5kW Vaillant Arothem+ heat pump at my house in St Albans. He is clearly an enthusiast for his work, and has a lot of expertise in the complex field of heat pumps. He went above and beyond to leave us with a tidy, efficient install. I'm delighted with the result. I would recommend him to anyone looking to install a heat pump.

Alex and Chris of Libtek Ltd. Replaced our gas combi boiler with a Valliant heat pump and a Sunamp heat battery (instead of a hot water tank). I have encountered many contractors over the last 17 years of property ownership and numerous projects. I can say with conviction that this team is up there with the best. Excellent communication throughout, stuck to the schedule and the quote, dealt with any unusual challenge (like mounting both units at first floor level) and even helped to sort out some small issues with the various Apps at the end of it all. I can thoroughly recommend Libtek Ltd.!

I'm very pleased with Alex's workmanship. I would definitely, highly recommend Libtek Heating. Alex was always on time, professional and his work has been excellent. The ecoTEC plus boiler and pipework look impeccable, with no soldering in sight! Very neat.

Alex and his team installed a brand-new central heating system in our three-bedroom house. Before the work, the house lacked any form of central heating. They fitted a new gas boiler, water softener, nine column radiators, new pipework, and a new shower system. They also removed the old electric wall radiators, immersion heater and water tank. Throughout the works they were super professional and friendly. Alex answered all of our questions, particularly when it came to selecting the right central heating system for our needs. Genuinely couldn't be happier with the results, highly recommend!

I wanted to make the change from a gas boiler to a heat pump and libtech explained everything to me thoroughly and did the work professionally and to the highest standard, I was very impressed with the speed, tidiness and quality of the work. Thank you very much!
