Mo, and his boys were very professional, using top quaily materials, and finished our home Air Con install so that it looked really great. They took great care, down to taking shoes off and laying the cling film on the carpet. I am so glad we worked with Mo and his team. Highly recommend.
Absolutely amazing team. Ordered a new cylinder and it was ordered and arrived within 24 hours. Call out was free of charge. Extremely professional team, left no mess at all! Highly recommend for a fast and professional service!
Excellent service. Great communication and advice. Prompt service and the job was completed the same day. I was not there on site, so, the engineers kindly sent me several photos of the work done. All looks neat and tidy. Really pleased and will happily recommend Mo and his team. Great service. Thank you very much.
We were abroad on our honeymoon when we were told our boiler had broken down and was deemed irreparable. It was freezing back in the UK and we wanted it resolved before we arrived home but after contacting several other companies it felt like a hopeless task. We contacted Let's Heat LTD and spoke to Mo who straight away made things easy. He re-contacted us on WatsApp to discuss and arranged to call a family member to meet him at our property that day so that he could inspect the system in order to provide an accurate and very reasonable quote. He guaranteed installation within 72 hours before we arrived home, all without a deposit or a single penny paid before the work was carried out. He was left at our house un-supervised for much of the day, the work was carried out to a high standard, installing the new boiler, replacing the FLUE, flushing the system, discarding the old boiler, reconnecting the system to our HIVE thermostat and registering the new boiler with the manufacturer. The house was left clean and tidy and he had even set the system up so the house and water would be heated for our return. I can't thank Mo enough for allowing us to enjoy the rest of our honeymoon worry free. I would 100% recommend Let's Heat Ltd and we will not hesitate to use Mo again for further work.
Let's Heat Installation provided one of the best services I've ever experienced. My previous boiler was roughly 20 years old and needed to be replaced; Because of how weird the pipe layouts are in the house, I realized this wouldn't be an easy task. Furthermore, we've recently installed a new kitchen unit for the boiler, and previous engineers left me with little or no choice when it came to installing the boiler around the unit without having to fully dismantle it. I contacted Let's Heat, and they agreed to come out the next day to inspect the boiler and give me a quote. The quotation was sent through email in a digital format. It was as simple as clicking the link in the email and accepting the offer on their website. The job began the next day (day two). The boiler was installed successfully and my unit left intact. The radiators were cleaned out on day three, and all trash and debris were removed. The boiler appears to be in excellent condition (very quiet), and the pipework appears to have been professionally installed. Thank you so much for your excellent service 'Let's Heat' you deserve alot more than 5 stars.
