I found Heatable through Which. To be honest, I had never heard of the company, but read through the reviews and decided to look at their website. After answering a few simple questions online, Heatable recommended a number of different boilers which would be suitable for my property. Although their price was very similar to other well known companies, when I looked through what was included in the installation, there were extras which other companies did not offer. The guarantee period for the boiler is also a lot longer than some other companies offer. I ordered my boiler and Hive through Heatable and chose my installation date. I then uploaded the photos as requested. The entire process was very simple. Heatable emailed me the night before the installation and gave me the details of my installer, Danny, along with a photo. I also received tracking information for the boiler and Danny gave me a courtesy call as well. Danny and his team arrived on time and have carried out the work to a very high standard. They were friendly and helpful, ensured that the areas they were working in were appropriately protected and cleared up after themselves. Danny talked me through the boiler and Hive and everything was completed within 4 hours. He also explained that I would need to ensure that I had the boiler serviced every year to maintain the 10 year guarantee. Heatable and Danny have been very friendly and helpful and I would certainly use them again in the future.
