How Long Does A New Boiler Installation Take December 22, 2025 A new boiler installation is a significant upgrade for any home, and one of the first questions homeowners ask is how long the work will actually take. While every property is different, understanding the typical timescales can help you plan around the installation and set realistic expectations. This guide explains what affects installation time and what usually happens on the day. What Influences the Timescale of a Boiler Installation In most homes, a new boiler installation can be completed within one day, but this depends on the type of system being installed and the work involved.

This is usually the quickest option and often takes between four and six hours. Pipework, flue position and controls are already in place, which keeps disruption to a minimum. Time Required When Changing Boiler Type Changing the boiler type, such as upgrading from a regular boiler to a combi boiler, takes longer.

In these cases, installation usually takes one to two days depending on the property layout and heating system design.

Moving a boiler to a loft, garage, or different room often involves extending pipework, rerouting the flue, and ensuring ventilation and access meet current regulations.

This may include upgrading old pipework, replacing outdated controls, or powerflushing the system to remove sludge and debris.
