    "Omg TopFlow were AMAZING! I called up as was battling the pressure system on my boiler and could not understand why it kept dropping. Plamen, promptly returned my call and it just so happened he had a gap in his schedule to come round and view the issue. Within seconds of approaching he spotted some wet on our floorboards and discovered a hairline fracture on the pipe underneath. Whilst he he fixed the pipes, sorted out our missing thermostat and rigged everything up to an up-to-date system. Amazing workmanship, thorough, talked through everything and really reasonably priced job. I have already spoken with him about a next job to install some radiators. I couldn’t thank him enough - we are warm tonight."

    "I was first inclined to call Plamen because I could see from the uploaded photos that his work was of an obviously high standard. On my call I said I had successfully replaced a couple of tap cartridges but unfortunately both isolation valves in the pipe work were now weeping water. He said if his workload the next day went to plan he would attend, even though I had said it wasn’t by any means an emergency. He quickly followed up with a text, setting out his charging structure, which I appreciated because it demonstrated this was a plumber who was organised about both his time and his business. The rates quoted were most reasonable, even before taking into account the quality of his work I had already noticed for myself. He duly called the next day, arrived in the afternoon and swiftly swapped over the isolation valves. The work was done in exactly the manner expected and in line with my preconceived view of his plumbing skills. Highly, highly recommended. My new plumber of choice."
