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.

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.

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!

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

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

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.

XKY Energy installed Air Source Heat Pump and Under Floor Heating in our house. The guys have been very professional, knowledgeable and helpful throughout the process and we are very happy with the results. Great attention to detail, respect for the building and can-do attitude. Highly recommended!

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!

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.
