Alto Energy Ltd

I wanted to publicly express my gratitude to this company. I was lucky enough to qualify for a free air source heat pump, radiators. Water heater and ceiling insulated which was installed January 2025. I am not on benefits but I am a single income household. Before this system was installed I was spending £250 per month trying to heat just 1 room of my freezing cold house which had plug in electric storage heaters. I could never get the house above 11 degrees. I had a small water heater which was so old and inefficient I had to switch it on an hour before washing up or having a bath and only had about 2 inches of water before it ran out. After installation the engineers switched it all on and my house reached 20 degrees in every room with a constant supply of piping hot water. All the engineers were lovely people friendly and efficient, left no mess. Today I have had the system serviced again free of charge and again received nothing but a friendly helpful and professional service. The system has transformed my life, I have been cosy all winter with lovely deep relaxing baths. My bills have reduced to £88 per month as well. I am so happy and cannot thank you all enough. I recommend 100%

Alto Energy provided a fantastic service from the first telephone contact to the completion of a complete Air Source Heating system. All my fears and enquiries were dealt with promptly and professionally at all times. All the surveyors and plumber engineers provided a very high standard of work throughout and I now have a really toasty home with no cold areas any longer. I would and will recommend Alto Energy Ltd to one and all. Richard Holloway

We honestly can’t recommend Alto Energy highly enough. Before the installation, our home was freezing despite running multiple heaters every day, and our energy costs were extremely high. Since the new system was installed, the difference has been unbelievable. Our home is now genuinely warm throughout the day, energy usage has dropped dramatically, and the hot water performance is excellent. The installation itself was carried out by SW Eco Solutions, and the whole experience from start to finish was professional, well organised, and reassuring. Most importantly, we finally have a warm, comfortable home for our children — something that simply wasn’t possible before. This has been a life-changing improvement for our family and has given us the confidence to continue our journey towards a fully eco-friendly home. We’re absolutely delighted with the results and extremely grateful.

Brilliant service! Tech advice was excellent, fault diagnosis for a GSHP system over the phone and new control unit sent out. Advice available to help with fitting and set up. Old unit returned and immediate refund for exchange item credited to my card. All Alto staff very helpful and act immediately in the interests of customers. Very appreciative.

I am new to heat pumps after many years of using gas heating. Alto Energy has helped to make the transition smooth, simple and problem free. I have just had my first service and Ryan Birch was professional, efficient and patiently explained everything, answering my many questions. He was polite, thoughtful and understanding. I couldn't fault the company and service that I have received. Thank you.
