Alex did a brilliant job at our house. We had a whole new heating system put in and Alex was always there to answer any questions we had and talk things through with us. Alex really cares about the job he does, and I would definitely recommend Libtek to others.

Had a vaillant air source heat pump fitted by libtek, can’t fault the workmanship, nice and tidy, knew what he was doing, set up and continues to help with the ongoing working of pump, I’m really pleased with everything done, especially as it is running now with solar panels and saving me loads of money compared to the oil I was having to buy, highly recommended

Excellent from start to finish. Alex and his team worked very professionally installing a Vaillant combi- boiler. My old system was updated and has substantially reduced my gas consumption. Work was carried out in good time with a minimum of disruption. Thanks Alex - no hesitation in recommending you 10 out of 10

Alex fitted a new boiler for my mother and I would recommend him to anyone because not only did he do a great job but he was really friendly and he explained everything he was doing so that she felt reassured and he wouldn’t leave until she was fully confident in how to use her new boiler.

Really happy with the work completed and the after sales service too. The system was set up according to our needs and we’re happy with the advice they continue to provide for the “fine tuning” of the system. All the guys were friendly and tidy, arrived on time and completed the work within the budgeted timescale.
