Martin and John were both amazing! I had full trust in their capability and was comfortable leaving them home working on the project while I was at work. They worked non stop to get the work done quickly. We had a bit of an issue with which was not related to their work, where my existing pipes could not candle the pressure from the new boiler and also, my pipes where corroded. Luckily it did not make much damage as they spotted it immediately and cut off the supply. We had to replace all the pipes from copper to plastic as they’re were many spots on the flat where the pipes were damaged. Fortunately, Martin and John were willing to add that to the job at short notice as they finished the original project way ahead of time. I now have a fantastic heating system and hot water on depend with high pressure! I will definitely recommend Martin and John to anyone and everyone. You will not be disappointed. Thank you both :)
