Replacing your boiler is one of the most important upgrades you can make to your home’s heating system. Whether your current unit has broken down or you’re upgrading to a more efficient model, it’s natural to wonder how long the process will take. While the time required can vary depending on your property, system type, and complexity, understanding what to expect helps you plan ahead and minimise disruption.
What Affects The Duration Of A Boiler Installation
The length of time needed for a boiler installation depends on several factors. A simple like-for-like replacement can often be completed within a day, but more complex upgrades or system changes may take longer.
Replacing An Existing Boiler In The Same Location
If your new boiler is going in the same place as your old one, this is usually the quickest option. Engineers can often complete this type of installation in around 4 to 6 hours, as minimal pipework or structural changes are required.
Changing Boiler Type
If you’re switching from a conventional or system boiler to a combi boiler, the process typically takes one to two days. This is because additional pipework, system flushing, and potentially removing water tanks or cylinders are involved.
Relocating The Boiler
Moving a boiler to a new location, such as from a kitchen to a loft or utility room, adds extra time. Engineers may need to reroute pipework, adjust the flue position, and ensure gas and water connections meet safety standards. In most cases, this type of job takes two to three days to complete.
System Upgrades And Power Flushing
If your home’s heating system needs cleaning or upgrading before the new boiler can be installed, expect the work to take longer. Power flushing and adding new controls, filters, or radiators can add a day or more to the overall project.
Preparation Before Installation
Before the engineer begins, they’ll carry out a survey to check compatibility and safety. This includes assessing gas supply, ventilation, and flue positioning. Having this inspection done early helps ensure the actual installation runs smoothly and avoids delays.
Post-Installation Testing And Handover
Once the boiler is fitted, your engineer will perform a series of safety and efficiency tests. They’ll check for leaks, confirm correct pressure, and demonstrate how to use your new controls. The process also includes registering your boiler’s warranty and ensuring your system meets current regulations.
Typical Installation Timeline Summary
Here’s a quick breakdown of what to expect:
- Like-for-like replacement: 1 day
- Changing boiler type: 1–2 days
- Relocation with new pipework: 2–3 days
- Full system upgrade: Up to 3 days
Planning ahead with a trusted heating engineer ensures the installation is completed efficiently and safely, with minimal disruption to your home.
