Smartheat London was able to answer all my questions about my broken boiler. The free quote was carefully explained and several options were given to me without any pressure. The job was booked in a short amount of time and the engineer was on time and carried out the job without much disruption. I’ve had engineers come before that made me feel slightly uncomfortable with constant phone calls but this wasn’t the case with Smartheat London. I will definitely book with them in the future and recommend them to those with any heating and plumbing issues. More...

Chris and his crew installed a new combi boiler at my house and performed a conversion from the old vented system (with the water tank in the loft) to the modern unvented system. The quality of the work they did is absolutely fantastic and they carried it out in a timely fashion, while being tidy, clean and mindful of my property. I would recommend SmartHeat London with no reservation. They do truly impressive work at a great price. More...

These guys saved the day! I found my boiler had failed the day before and although I didn't live in the London area, Jiri agreed to go out of his way to get me a boiler fitted the next day. I sent sent a few photos of the existing boiler and flue & received a professional quote -which beat local quotes hands down. I was told the plumber would come especially the next day to fit it. Alex turned up and just got on with the job! Very polite and friendly, explained everything as he went along. He showed me how everything worked, Jiri then called to ensure I was happy. Excellent! Highly recommended! More...

Heat Pump Installation
How Does An Air Source Heat Pump Work?
Air Source Heat Pump
They transfer heat from outside to inside your house at temperatures as low -20°C as there is always heat in ambient air. Also they include an internal defrost cycle system ensuring operation in all seasons.
They work similar to the technology in a refrigerator but in reverse.
