I called Pimlico Plumbers as I needed someone to service my boiler. The helpdesk was super reactive and professional. The engineer, on the contrary, was a disaster: first thing he asked to view the user manual, which we didn't have. He was staring at that thing like it was the first time he saw one... Then he played a YouTube video to see how to service the boiler............. I called the helpdesk complaining about that, but I was told that it was impossible as their engineers were all super professional... I wish I had filmed that! So, he left saying that he found an air gap issue, but he rectified it and, quote, "any further issues with internal air gap, further investigation required at the hourly rate". The next morning, at 5am, the heating system kicked in and woke us up making a dreadful noise, gurgling, bubbling for almost 30 minutes! For the entire period of our holidays, every morning it was the same "concert". I eventually wrote Pimlico Plumbers, but they've never doubted for a second that their engineer was the best, that he carried out a marvellous service and that the issue was pre-existing... Total denial! The boiler was working like a swiss watch before but after the King of Plumbers job, we now live with a mumbling cylinder that wakes us up every single morning. Unreliable, unprofessional, uncaring, irresponsible, in denial, to avoid like the plague! Paid £138 for breaking my boiler, now I have to look for someone else and pay to rectify a problem that wasn’t pre-existing.
