What our renewable energy clients say

Zoltan fitted our biomass boiler and solar thermal system in tough weather but he was always cheerful, professional and very dedicated toward delivering a first class result. I would thoroughly recommend him.

Jason, Carlops

I can’t recommend Zoltan’s workmanship highly enough. He is hard-working and has excellent attention to detail whilst getting the job done to a tight timescale. His communication skills are first rate and he kept me as client fully informed of progress at all times. I would have no hesitation in using his services again in the future.

Robin, Glasgow

Couldn't ask for more. Zoltan debugged all aspects of my heating system from faulty controllers to undersized radiators and noisy pipes. He explained all the options making best use of existing components, happily answered all technical questions, and helped me pick and place new radiators as required. He also helped me pick the right smart thermostat and plan ahead for underfloor heating in our extension. Very thorough, great communication, highly recommended!

John

Absolutely first class in terms of knowledge and ability. Would recommend in a heartbeat. Second to none. Nice guy too!

Derek

If you want someone who is a craftsman and who takes great pride in doing the best job possible, then there is no doubt in my mind that Zoltan, XKYenergy, is the best. I have absolutely no hesitation in recommending XKY Energy. After a recent crisis with pellet store, XKY came to my rescue and solved the problem in a speedy, professional manner. Highly recommend this company as I know I can rely on XKY

Dianne, Fintry

We've used Tibor @ XKYEnergy on multiple occasions now and he always delivers professional, high quality service. From boiler installation, through servicing to upgrading our radiator valves to evohome. I couldn't recommend him enough.

Marcin Sewera

XKY Energy installed Air Source Heat Pump and Under Floor Heating in our house.

Highly recommended!

Mr Woncek

XKYEnergy Ltd are a friendly and very knowledgeable company, providing excellent customer service. We have been using them for the last 3-4 years to service our biomass boiler and have always been pleased with the standard of service they provide. We would have no hesitation in recommending them to anyone!

Dawn Galmiche

Very professional, knowledgeable, helpful and courteous service. Zoltan took the time to go round our entire system, work it all out and explain it all to me. After the boiler service the system has been working so much better, a significant improvement. I'm very impressed and will definitely be using them again.

XKY Energy are highly skilled engineers and also really lovely people to deal with. They do the routine servicing of our heat pump, any emergency works, and they fitted our PV solar panels.

We had a Vaillant 12KW Arotherm Plus heat pump fitted at our house to replace a 30 year old gas boiler. This required a heat loss calculation to be prepared for the property, specification of new radiators and specification of heat pump.
XKY performed all the preparatory work to a high standard taking care to explain the process in an easily understandable manner. This was very important to us as we were retrofitting heat pump technology to an existing property and we had to be reassured it would work. Tibor was very patient in answering all of our questions and a quote was prepared timorously.
The installation took place over two weeks and the radiator and heat pump installers were all very polite and friendly and again were always available to answer questions, clearly understanding the technology. The installers took pride in their work and were very good at leaving a tidy, clean workplace at the end of each day keeping disruption to a minimum. The Directors of the company also visited the installation works from time to time providing added confidence in the process.
Following completion of works, minor snags were attended to quickly and without complaint.
The heat pump has now been installed for two months during which time we have experienced the coldest winter for several years with temperatures dropping as low as -9C. Throughout this time, the heat pump has exceeded expectations in heating the entire house significantly more economically and efficiently than the previous gas boiler would have done.

This company recently avoided me having to pay thousands to replace a solid wood floor due to potential water damage. They quickly analysed the problem, mice gnawing through plastic water pipes, and replaced the pipes concerned with copper ones. They kept me up to date via their main office and the engineer concerned at all times. On the same day I had already contacted 4 plumbers only one of which responded to say they could not attend. I have used XKY for the installation of an Air Source Heat Pump system and they provided top quality service and follow up servicing. They pride themselves on customer service and that shines through.

The XKY team have been excellent. They managed the installation of our heat pump with care and creativity, finding ways to minimise the impact of the work on our old house. The team are courteous and friendly at all times, and willing to explain and support us as we learn how to use the new system. I highly recommend XKY.
