What’s involved in a boiler replacement in London?
A typical boiler replacement in London
might sound daunting, but Ninja Plumber makes the process smooth, transparent, and hassle-free from start to finish. It begins with a free, no-obligation home assessment where one of our expert engineers will inspect your existing heating system, assess your water pressure, property size, and discuss your usage needs. This ensures we recommend the best boiler type — whether it’s a combi, system, or conventional model.
Next, we provide a clear, fixed quote with no hidden charges. Once approved, we schedule your installation at a time that works for you — and in many cases, we can carry out the install the very next day. On the day of installation, we arrive on time, protect your flooring and work areas, and get to work immediately. We remove your old boiler, prepare the pipework, install the new unit, and carry out all necessary upgrades such as thermostats or flue changes if required.
After installation, we fully test your new boiler, commission the system, and provide a Gas Safety Certificate. We also register your new boiler with the manufacturer to activate your warranty, which could be up to 10 years. Lastly, we walk you through the controls and ensure everything is tidy before we leave. With Ninja Plumber, every step is handled with care, professionalism, and clear communication.
