We recently replaced a 15-year-old boiler in a semi-detached home in Harrow. The old unit had become unreliable and was failing its annual service. We installed a new combi boiler in the same location, updated the flue outlet, and fitted a new smart thermostat, completing the full job in a single day. The homeowner noticed a significant improvement in heating responsiveness from the very first evening.
