Sami and his team were absolute life savers. Our boiler and hot water broke down in the coldest week of 2023, with us having a newborn at home and family visiting. I was referred to Sami by the manufacturer, Worchester Bosch. Sami visited the next day and I at no point felt pressured into buying anything; in fact, Sami and his colleague spent 30 minutes fixing our old boiler (successfully so we had heating and hot water that night) without even charging us for that! Even though Sami fixed the boiler, I still decided that we needed a new one and Sami and his team came the next day (after responding to my emails up until 11pm on the day of the quote, explaining me the pros and cons of different boiler options, with a seriously impressive expertise in boilers!) and started installing the new boiler, updated our heating control and thermostat, and installed a Hive system. They worked until 7:30pm on a Friday to ensure that we have a warm and spotless house for the weekend, and came back on Monday to check everything one last time. The price we paid was very reasonable, compared to 3-4 quotes that I had obtained beforehand (also as Sami and his colleague were competent enough to install the flute without requiring scaffolding, which for some reason all the other installers said they would need (which would have been not only expensive but also an annoyance to our downstairs neighbours as we don't have access to the garden/don't own the flat downstairs). All in all, Sami and his team are the best tradesperson service I've ever received in London!
