"Don't Hesitate"

I recommend Libtek unreservedly. Alex is a very smart, personable and helpful professional who installed our system (5kw Arotherm) in about a week. It's too big an investment to leave to chance, and Libtek were recommended by a friend (whose five star review also appears on this page). I'm sure that otherwise very competent plumbers would struggle to optimise the performance of these systems without the necessary training and plenty of experience and I'm sure we're saving as much money on our bills as is possible. The house is always warm.

"Major retrofit of heating system plus"

I approached Libtek unsure of how I could replace an ancient gas boiler that was close to the end of its life and adapt my 1930s semi to benefit from the power from my solar panels. Alex visited and made many innovative suggestions whilst listening to my requirements. I am very happy with the air pump heating system with a Thermino heat battery for the hot water. The heat pump is above the garage roof and the controls and heat battery in the cupboard that had previously held the hot water tank. The system is working well, and I like having the house at constant temperature. This was a major project, as all the radiators were replaced, an in addition I wanted an electric towel rail and induction hob installed. Alex and his team worked effectively together and were very considerate, reliable and hard-working and I could work from home and leave them working in the house. The work was done well, including removing the redundant tanks and gas piping and covering up the holes etc. The team coped with a few hiccups, such as replacing an old mixer tap that started leaking with the higher pressure. Alex has been very good at consulting during the planning and execution, and dealing with the paperwork. I am extremely pleased that I chose Libtek.

"Air Source Heat Pump Installation On A 5 Bedroom House "

First Class Experience with Alex and the Team at Libtek. I’d been looking to get an ASHP (Air Source Heat Pump) installed as we have Solar Panels + Battery and drive EV’s. Libtek was recommended to me by a good friend of mine. With all works we get done I always obtain multiple quotes. Alex gave great advice and showed us all the options. I thought I’d give Octopus a go too for a survey and quote too. Their advice was terrible as the installer said I would need 75mm surface pipes installed and to move walls! Needless to say I decided to go with Libtek and I’m glad I did. Alex was excellent at communicating and kept us updated with any changes. During the installation there were a few curve balls (unexpected challenges) but he told us and overcame them with no problems. The team have great attention to detail and this was really appreciated. For example the old gas flue needed taking out and new bricks to seal up the hole. Alex found the right colour bricks and sealed it up nicely. We purposely had the Viessman Heat Pump installed over the Summer so we wouldn’t need the central heating and there was no disruption with the hot water as the immersion heater on the tank was used during the works. The installation took around 10 days, and I’m am very pleased with the result. I’m looking forward to seeing how the new central heating system handles the U.K. winter, but I’m very confident it will do it well - and even if there are any issues I know Alex will look after us. We would definitely recommend Libtek.

"Flexible knowledgeable heat pump expert highly recommended"

From the start looking at our house for the heat pump to the end with a successful install Libtek have been amazing. Alex had great comms answered all my many questions and was flexible to our suggestions. We had a slightly unusual install with our water tank location and there was not a problem that couldn't be solved. It was great that they are heat geek certified for that extra confidence. We had four separate surveys and every one over sized our pump which has been working well at 400% since April.

"Alex is a trusted professional"

Alex is a trusted professional. He completed a total overhaul of our plumbing system when we purchased a new property in 2020. This included a change to a combi boiler and the replacement of all pipework throughout the house. Since then he has completed ad hoc plumbing work during our house renovation and carried out the annual boiler service. Alex is a great plumber, reliable and easily contactable. I recommend him to anyone who needs a plumber.

"Ground source heat pump replacement "

We had libtek replace our ground source heat pump. They were excellent from start to finish. They kept us informed every step. This was a complicated job, made easy by libtek. They even installed their own equipment to monitor the system and have made a few adjustments to make the system run efficiently as possible. We would like to thank Alex and the team, they spent 12hrs on a Friday installing the new pump and stayed to make sure it was running smoothly
5star service brilliant company

"Great work from a heat pump enthusiast"

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.

"Very pleased with the service from Libtek"

Alex has been knowledgeable and diligent, designing a heating system that really makes the most of our heat pump. So far, the summer has been seamless, with a comfortable home and hot water available whenever needed, but I’m excited to see how it performs in the winter.

"Very honest and reliable"

"5 star installation from Libtek"

Alex and his team did a fantastic job replacing the boiler at my property with a Vaillant heat pump and water cylinder. They were very professional and their work is extremely neat, especially the amazing job that they did fitting the water cylinder into an existing cupboard in the laundry room.
